Abstract
Orychophragmus violaceus (OV) and chicory (Cichorium intybus L., CC) can be used as fresh or dry forage for animals. To determine whether OV and/or CC have beneficial effects on performance and egg quality, a total of 1212 28-wk-old Beijing You Chicken (BYC) laying hens with similar performance were randomly allocated to 4 groups with 3 replicate pens per group, and 101 birds per pen. The birds were fed a basal diet (control), the basal diet + OV (3.507 kg/d/pen), the basal diet + CC (2.525 kg/d/pen), and the basal diet + OV + CC (OVC, 1.7535 kg/d/pen OV + 1.2625 kg/d/pen CC) for 3 wks after one wk of adaptation. The results showed that egg-laying rate was not affected by OV, CC and OVC (p > 0.05), but weekly average egg mass was significantly increased by OV and CC (p < 0.05). The feed egg ratio in the CC group (2.82) was significantly lower than that in the other three groups (p < 0.05). The eggshell thickness (EST), albumen height (AH) and Haugh unit (HU) were decreased by OV and CC (p < 0.05); while yolk color (YC) was increased in the CC and OVC groups (p < 0.05). Egg grade was decreased by OV (p < 0.05). Sensory evaluation showed that there was a trend for increased YC in OV, CC and OVC (p = 0.089). Serum total protein was significantly lower in OV group than those in the control and CC group (p < 0.05); serum albumin content was significantly decreased in OV, CC and OVC groups (p = 0.006). Serum glutathione peroxidase activity in CC and OVC groups was significantly higher than that in the control group (p < 0.05). In conclusion, the present study suggests that CC had a better effect on the performance of the native laying hens than OV. The OV and CC affected egg quality, while YC was increased in CC and OVC groups. The OVC improved YC and serum antioxidative properties of native laying hens without affecting the performance.

Abstract
Objective: To analyze the clinical characteristics of children with multisystem inflammatory syndrome (MIS-C) associated with SARS-CoV-2 in China, and to improve the understanding of MIS-C among pediatricians. Methods: Case series study.Collect the clinical characteristics, auxiliary examinations, treatment decisions, and prognosis of 64 patients with MIS-C from 9 hospitals in China from December 2022 to June 2023. Results: Among the 64 MIS-C patients, 36 were boys and 28 were girls, with an onset age being 2.8 (0.3, 14.0) years. All patients suffered from fever, elevated inflammatory indicators, and multiple system involvement. Forty-three patients (67%) were involved in more than 3 systems simultaneously, including skin mucosa 60 cases (94%), blood system 52 cases (89%), circulatory system 54 cases (84%), digestive system 48 cases (75%), and nervous system 24 cases (37%). Common mucocutaneous lesions included rash 54 cases (84%) and conjunctival congestion and (or) lip flushing 45 cases (70%). Hematological abnormalities consisted of coagulation dysfunction 48 cases (75%), thrombocytopenia 9 cases (14%), and lymphopenia 8 cases (13%). Cardiovascular lesions mainly affected cardiac function, of which 11 patients (17%) were accompanied by hypotension or shock, and 7 patients (12%) had coronary artery dilatation.Thirty-six patients (56%) had gastrointestinal symptoms, 23 patients (36%) had neurological symptoms. Forty-five patients (70%) received the initial treatment of intravenous immunoglobulin in combination with glucocorticoids, 5 patients (8%) received the methylprednisolone pulse therapy and 2 patients (3%) treated with biological agents, 7 patients with coronary artery dilation all returned to normal within 6 months. Conclusions: MIS-C patients are mainly characterized by fever, high inflammatory response, and multiple organ damage. The preferred initial treatment is intravenous immunoglobulin combined with glucocorticoids. All patients have a good prognosis.

Abstract
Objective: To perform a health economic evaluation of telemedicine diabetic retinopathy (DR) examination with a non-mydriatic fundus camera in China and to investigate the optimal examination interval. Methods: Based on 18 peer-reviewed articles related to epidemiology, clinical trial, and health economic evaluation of DR, surveys from 9 ophthalmologists in 3 tertiary hospitals in China, price lists for medical services in each province, and the negotiated price in 2021, a Markov model was conducted to evaluate the cost utility of telemedicine eye examination for diabetes mellitus patients aged 45 and older from the health system perspective. Separate analyses were performed for no examination and for examination intervals of every 1 to 5 years to predict the lifetime health gain, including cumulative days of blindness, cumulative life years, and quality-adjusted life years (QALYs), and costs for unilateral and bilateral direct medication with a 3.5% discount rate. Results: The cumulative days of blindness in the absence of a DR screening were 2 375.00 days, and ranged from 701.00 to 738.00 days for five different DR screening interval programs. The cumulative life years for no screening and five DR screening programs ranged from 27.120 34 to 28.005 00 years, with QALYs ranging from 9.502 96 to 9.875 02. The direct medication costs in the absence of a DR screening program were 72 785.00 yuan for both unilateral and bilateral scenarios. For the five DR screening intervals, the direct medication costs ranged from 52 065.00 to 52 408.00 yuan for unilateral and 79 100.00 to 79 603.00 yuan for bilateral. Comparing the incremental cost-effectiveness ratios between the DR screening intervals and no screening, the 1-to 5-year intervals were dominant in the unilateral scenario (between -56 368.54 and -55 523.75 yuan/QALY). In the bilateral scenario, the ratios ranged from 17 469.07 to 18 325.15 yuan/QALY. Using a willingness-to-pay threshold equal to the per capita GDP (80 976 yuan/QALY), the 1-year DR screening interval had an 85.9% probability of being cost-effective and a 55.2% probability of being dominant in the unilateral scenario. In the bilateral scenario, the 2-year interval held a 61.4% probability of being cost-effective. Conclusions: Analyses on the remote fundus consultation in diabetic patients and health economics based on the Markov model indicate that telemedicine DR examination through a non-mydriatic fundus camera can be effectively employed for diabetes mellitus patients in China. DR examination every two years is recommended for general diabetic patients, and DR examination every year may be chosen in developed areas.

Abstract
Objective: To explore the influencing factors of AIDS-related deaths among HIV-infected patients in Shandong Province, to help reduce the risk of death and prolong survival time. Methods: The study population was HIV-infected patients in Shandong Province from 2017-2021, and Cox proportional hazards regression model was used to analyze the influencing factors of AIDS-related deaths and deaths within one year of confirmation. Results: Among 14 700 HIV- infected patients reported in Shandong Province in 2017-2021, 351 AIDS-related deaths occurred, accounting for 2.4% (351/14 700). The results of multifactorial Cox proportional hazards regression model analysis showed that the risk factors for AIDS-related deaths among HIV-infected patients included education level of junior high school, high school, and secondary school (aHR=1.37, 95%CI:1.01-1.84), sample source from healthcare institutions (aHR=1.61, 95%CI:1.22-2.12), duration of disease in AIDS stage (aHR=9.86,95%CI:6.86-14.19), baseline CD4+T lymphocytes (CD4) undetected (aHR=3.93, 95%CI:2.69-5.75), duration of antiviral treatment (ART) <6 months (aHR=3.46, 95%CI:2.42-4.93) and no ART (aHR=1.45, 95%CI:1.02-2.07), final CD4 <200 cells/μl (aHR=3.51, 95%CI:2.18-5.65) and final CD4 undetected (aHR=10.58, 95%CI:6.15-18.19), and final viral load (VL) values of 50-999 copies/ml,≥1 000 copies/ml and undetected (aHR=2.59, 95%CI:1.07-6.26; aHR=9.50, 95%CI:5.60-16.12; aHR=15.33, 95%CI:8.91-26.36). Factors with higher risk of AIDS-related deaths within one year of confirmation of HIV-infected patients included samples originating from healthcare facilities (aHR=1.68, 95%CI: 1.19-2.36), AIDS stage of disease (aHR=10.60, 95%CI:7.13-15.75), baseline CD4 undetected (aHR=3.71, 95%CI:2.34-5.90), duration of ART <6 months (aHR=4.30, 95%CI:2.85-6.49) and no ART (aHR=2.05, 95%CI:1.35-3.13), final CD4 <200 cells/μl (aHR=5.45,95%CI:2.04-14.60) and final CD4 undetected (aHR=20.95, 95%CI: 7.69- 57.04), and final VL values of 50-999 copies/ml, ≥1 000 copies/ml and undetected (aHR=15.21, 95%CI: 2.54-91.21; aHR=42.93, 95%CI:9.64-191.20; aHR=61.35, 95%CI:13.85-271.77). Conclusions: Expanding the coverage of testing, promoting early detection and treatment, strengthening regular follow-up and the test of HIV-infected patients, grasping the progress of the disease to provide accurate management and treatment are important for reducing the disease mortality rate and prolonging the survival time of HIV-infected patients.

Abstract
CONCLUSION Upon wound formation, the wound temperature rises in the first 3-4 days until reaching its peak. It then falls at about one week after wound formation. In the second week after wound formation, the wound temperature decreases steadily to the baseline indicating a good wound condition and progression towards healing. While a continuous high temperature is often a sign of excessive inflammation or infection, which indicates urgent need of intervention and treatment.

Abstract
BACKGROUND Combinational therapy such as taking tranexamic acid while using laser treatment has been proved potential efficacy by many experiments. However, there is few research which contains large samples and consistent observations. OBJECTIVE We evaluated clinical efficacy and safety of a new systemic treatment of drug-laser-photon therapy. METHODS Retrospective and randomized investigator-blinded study of 75 patients with mixed type melasma was analyzed. At each visit, standardized photographs were taken using VISIA. Modified melasma area and severity index (mMASI) scores were marked using photographs by two dermatologists. RESULTS The mMASI score decreased significantly from 6.92 to 3.84 after the treatment. The VISIA analyze right cheek data shows: Spots (from 49.67 ± 3.43 to 56.09 ± 3.31), UV spots (from 41.39 ± 24.45 to 44.56 ± 25.86), and Brown spots (from 23.97 ± 17.89 to 28.16 ± 21.28) are statistically increased (p = 0.035, p = 0.018, p = 0.07). All patients feel varying degrees of improvement, about 10.17% felt very much improved, 30.51% felt much improved (51%-75%), 45.76% felt moderately improved (26%-50%), and 13.56% felt little improved (1%-25%). LIMITATIONS This study was no control group. CONCLUSION The efficacy and safety profile of the combination of drug-laser-photon therapy systemic treatment in melasma patients has been proved. It has potential possibility to become a new, reliable, widely suitable therapy strategy.

Abstract
Paraphlomisyingdeensis (Lamiaceae), a new species from the limestone area in northern Guangdong Province, China, is described and illustrated. Phylogenetic analyses, based on two nuclear DNA regions (ITS and ETS) and three plastid DNA regions (rpl32-trnL, rps16 and trnL-trnF), suggest that P.yingdeensis represents a distinct species in Paraphlomis. Morphologically, P.yingdeensis is similar to P.foliatasubsp.montigena and P.nana, but can be distinguished from the former by its densely villous lamina and calyx, not decurrent base of lamina and bristle-like-acuminate apex of calyx teeth, and distinguished from the latter by its significantly taller plant (15-20 cm vs. 1-5 cm) and larger lamina (6.2-16.5 × 4-11.5 vs. 2-7 × 1.5-4 cm), densely villous stem, lamina and calyx and yellow corolla.

Abstract
BACKGROUND Vaginal tightening or vaginoplasty has been gaining popularity, while validated methods of evaluation and treatment are still lacking. Herein, we describe a bilateral wall tightening technique for vaginal laxity and evaluate the feasibility of this method. METHODS From April 2020 to September 2021, 25 women with vaginal laxity underwent vaginal tightening, and 22 women were included in this retrospective observational study. The inclusion criteria were as follows: participants with at least one delivery and reported vaginal laxity, but without a history of underlying diseases. Vaginal pressure tests and questionnaires were used to evaluate vaginal laxity and sexual quality before and 6 months after the surgery. RESULTS The study included 22 women (aged 29-46 years), and the follow-up period was 14.1 ± 3.3 months. The score based on the vaginal laxity questionnaire was improved as a result of surgery (preoperative median: 2.00, interquartile range [IQR]: 1.00-2.00; postoperative median: 5.00, IQR: 5.00-6.25, p < 0.001). The vaginal pressure increased from 2.3 ± 1.8 mm/Hg to 21.4 ± 3.7 mm/Hg. Sexual distress changed from 24.2 ± 8.9-16.1 ± 4.8 after surgery (p < 0.001), and sexual dysfunction with an average score of 20.1 ± 10.6 before surgery improved after the procedure (26.0 ± 10.8, p < 0.001). Women also reported improved scores in desire, arousal, orgasm, and satisfaction. In addition, there were no intraoperative complications or significant events during the follow-up period. CONCLUSIONS Bilateral vaginal tightening without mucosal excision is a feasible and effective surgical approach for the management of vaginal laxity.

Abstract
Objective: To explore the current situation of fetal heart defects in Yunnan Province and surrounding high altitude areas and the social factors affecting pregnancy outcome. Methods: This is a retrospective study. Pregnant woman who underwent fetal echocardiography and diagnosed as fetal cardiac defects in Yunnan Fuwai Cardiovascular Hospital from June 2017 to January 2021 were included. According to the clinical prognostic risk scoring system and grading criteria of fetal cardiac birth defects, the cases were divided into grade Ⅰ to Ⅳ. The disease distribution and proportion of each prognostic grade, pregnancy outcomes were analyzed and compared. The cases were divided into continued pregnancy group and terminated pregnancy group according to pregnancy outcome. The social factors that may affect the selection of pregnancy outcomes were analyzed by multivariate logistic regression analysis. Results: A total of 4 929 fetal echocardiography examination data were collected, and 4 464 cases (90.57%) were from Yunnan Province and surrounding high altitude areas. 2 166 cases of heart defects were finally analyzed, including 998 cases of congenital heart disease (CHD), 93 cases of cardiac tumors, cardiomyopathy and arrhythmia, 1 075 cases of foramen ovale, ductus arteriosus abnormalities and normal variations. The pregnant women were (29.2±5.0) years old with (25.6±3.8) gestational weeks. The number of cases with prognostic grade from Ⅰ to Ⅳ was 1 037 (47.88%), 620 (28.62%), 314 (14.50%), and 44 (2.03%), respectively. And 151 cases (6.97%) were not classified. The cases of normal variation and thin aortic arch development accounted for 42.66% (924/2 166), 5.22% (113/2 166), respectively. The top 3 diseases of grade Ⅱ were ventricular septal defect, coarctation of aorta and mild-moderate pulmonary stenosis, respectively, and their distribution was 11.63% (252/2 166), 3.92% (85/2 166) and 2.35% (51/2 166) respectively in all cases of heart defects, and 25.25% (252/998), 8.52% (85/998) and 5.11% (51/998) respectively in cases of CHD. Among the cases rated as grade Ⅲ and Ⅳ, most of them were complicated congenital heart disease, and the disease types are scattered. The more common cases in grade Ⅲ were complete transposition of great arteries (accounting for 2.40% (52/2 166) of all cases with heart defects, 5.21% (52/998) of all cases with CHD) and pulmonary artery occlusion (type Ⅰ to Ⅲ) with ventricular septal defect (accounting for 2.17% (47/2 166) of all cases with heart defects, and 4.71% (47/998) of all cases with CHD). In grade Ⅳ, single ventricle (0.74% (16/2 166) of all cases with heart defects, 1.60% (16/998) of all cases with CHD) and left ventricular dysplasia syndrome (0.65% (14/2 166) of all cases with heart defects, 1.40% (14/998) of all cases with CHD) are more common. A total of 1 084 cases were successfully followed up, and 675 cases were born, 392 cases were terminated, spontaneous abortion occurred in 17 cases. The proportion of terminated pregnancy cases was significantly increased from grade Ⅰ to Ⅳ, accounting for 5.24% (21/401), 27.78% (70/252), 89.54% (214/239) and 95.56% (43/45), respectively. Among the terminated pregnancy cases, those with grade Ⅲ accounted for the highest proportion (54.59% (214/392)). The distribution of terminated pregnancy cases was mainly complex congenital malformations or diseases with very poor prognosis (pregnancy outcome grade Ⅲ and Ⅳ), and proportion of terminated pregnancy with pregnancy outcome grade Ⅰ and Ⅱ cases (normal variation or good prognosis) accounted for 5.36% (21/392) and 17.86% (70/392), respectively. The results of multivariate logistic regression analysis showed that pregnant women with low education (high school and below: OR=2.73, 95%CI 1.26-5.93, P<0.001; illiteracy: OR=3.27, 95%CI 1.29-7.10, P<0.001) and low family income (Annual income<100 000 yuan: OR=2.47, 95%CI 1.69-5.12, P<0.001) were more likely to choose termination of pregnancy in case of fetal heart defect. Conclusion: In Yunnan province and the surrounding high altitude areas, the disease distribution of fetal heart defect is mainly simple or low-risk disease, but the complex malformation, especially the disease with poor pregnancy outcome, accounts for a relative high proportion. Pregnancy termination also occurs in some cases with good pregnancy outcome. The education level and family income of pregnant women may affect their choice of pregnancy outcome in case of fetal heart defect.

Abstract
BACKGROUND The relict genus Rehderodendron (Styracaceae), the species of which are restricted to mostly warm temperate to tropical climate in East Asia today, is known from fossil fruits and pollen in Europe during warmer periods from the lower Eocene to Pliocene. To infer which extant species are most closely related to the fossils, new data of pollen and fruit morphologiesy of six extant species, and additional new data of fossil pollen and previously described fossil fruits of Rehderodendron, are compared. RESULTS Both fossil pollen and fruits resemble a morphological mixture of the extant species R. indochinense, R. kwantungense, R. macrocarpum, and R. microcarpum, thus implying that these extant taxa and the fossil European taxa represent an old Eurasian lineage, whereas the pollen and fruit morphology of the extant R. kweichowense and R. truongsonense differ considerably from the fossils and other extant species investigated, and are considered to have evolved independently. CONCLUSIONS The palaeobiogeographical history of Rehderodendron reveals that its fossil members of the European lineage were most prominent during climatic optima such as the Palaeocene-Eocene Thermal Maximum (PETM), Early Eocene Climate Optimum (EECO) and Middle Miocene Thermal Maximum (MMTM). However, when during the Pliocene the climate changed to colder and less humid conditions, the genus went extinct in Europe but migrated eastwards, most likely in two dispersal events along the Tethys Sea prior to extinction. One of the former most westerly stepping stones is suggested by the refugial occurrence of R. microcarpum in the southeastern Himalaya, whereas R. macrocarpum and R. kwangtungense, the taxa distributed more to the east, might have migrated eastwards already before the Miocene.

Abstract
Argostemmaehuangzhangense, a new Rubiaceae species from E'huangzhang Nature Reserve, Guangdong Province, China, is here described and illustrated. A morphological comparison between the new species and its putative relatives, A.lamxayanum, A.laotica and A.verticillatum, is presented. The new species is mostly similar to A.laotica, but they can be distinguished from each other since Argostemmaehuangzhangense presents solitary flower (vs. 2-flowered inflorescences), flower lobes 4 (vs. 5) and anthers opening by longitudinal slits (vs. apical pores). In a preliminary IUCN Red List status of Argostemmaehuangzhangense this species is assigned as Vulnerable (VU).

Abstract
Idiopathic hypogonadotropic hypogonadism (IHH) is a rare endocrine disease characterized by gonadal dysplasia. According to whether the sense of smell is affected, this disorder is classified into Kallmann syndrome (KS) and normosmic isolated hypogonadotropic hypogonadism (nIHH). In this study, we reported a case of nIHH patient and explored the pathogenic mechanism of FGFR1 in nIHH. A FGFR1 variant (c.2008G>A, p.E670K) and a CEP290 variant (c.964G>A, p.D322N) were detected by the whole exome sequencing in this nIHH patient. Bioinformatic analysis revealed that this FGFR1 variant (c.2008G>A) causes structural perturbations in TK2 domain demonstrating that this variant result in FGFR1 loss-of-function and abnormal signaling. The identification of an additional CEP290 variant (c.964G>A) indicated that CEP290 might play a potential role in developmental abnormalities and inhibition of GnRH neuron release. A protein interaction network analysis showed that CEP290 was predicted to interact with FGFR1. In summary, our study identified the potential pathogenic mechanism(s) of the novel FGFR1 variant and indicated that CEP290 might play a role in the GnRH neuron migration route. Our findings expand the mutation spectrum of FGFR1 and CEP290 and provide a reference for clinical diagnosis and treatment of IHH.

Abstract
Capsular contracture is one of the most common complications of breast implants, which often leads to secondary surgery. Patients with unconspicuous breast contracture do not need treatment, while for those with severe symptoms, a capsule revision surgery is of great necessity, including a total periprosthetic capsulectomy and replacement with a new implant. However, if the capsular contracture happens in the submuscular space, it will be very difficult to release it completely, and it may lead to more complications such as damage to surrounding tissue. The new method of pouch can create a new subpectoral plane for the insertion of a new implant instead of a total capsulectomy, but this method is unsuitable for patients who have little breast tissue or thin skin. To solve this thorny clinical problem, we invented a double-headed separating instrument and came up with a novel operation method to release the capsular contracture, which opened from the nipple by the punctiform-incision approach and caused only a mild and undetectable trauma. This operation went off without a hitch, and the postoperative breast shape was good, and the breast felt and moved naturally. In addition, there were no significant complications throughout the one-year follow-up period. This case was an excellent demonstration of the novel breast capsular contracture release surgery using our optimized double-headed capsule contracture separator.

Abstract
Paraphlomisjinggangshanensis (Lamiaceae), a new species from Jiangxi Province, China, is described and illustrated. The new species is morphologically similar to P.intermedia, but can be easily distinguished from the latter by its cordate leaf base (vs. cuneate, decurrent), stem and calyx tube with glandular hairs (vs. short pubescent), and glabrous anthers (vs. ciliate anthers). A phylogenetic analysis, based on ITS regions, suggests that P.jinggangshanensis represents a separate branch in Paraphlomis and is closely related to Clade II. It is currently known only from Jinggangshan National Natural Reserve. Because of its limited distribution and small population size, the species was assessed as Near Threatened (NT) according to the IUCN Red List Categories and Criteria.

Abstract
Coronavirus disease (COVID-19) and tuberculosis (TB) are two respiratory infectious diseases with a high incidence of transmission, mainly via respiratory droplets and both can weaken the immune system and lower the number of CD4+T cells in patients. COVID-19 can occur before, at the same time or after the diagnosis of TB. Patients with pulmonary TB are more likely to have co-infection when they have a history of epidemiological exposure to COVID-19. At present, many cases of nosocomial infection of COVID-19 caused by ineffective prevention and control measures in tuberculosis hospitals have been reported successively at domestic and overseas. Therefore, it is urgent to strengthen the prevention and control of nosocomial infections in tuberculosis hospitals. The superposition of the two diseases can lead to a worsening prognosis, aggravating the patient's condition and making treatment more difficult. In addition, in the context of the new coronavirus epidemic, early recognition of co-infection with new coronavirus should be made when TB patients in chest hospitals present with symptoms such as aggregated fever or progressive disease. At the same time, we should focus on identifying the clinical and imaging manifestations of TB and COVID-19 co-infection. At present, research on COVID-19 complicated with pulmonary TB is scarce, and there are disputes on many aspects. As a country with a high prevalence of tuberculosis, it is of great practical significance to identify the clinical characteristics, outcomes, and treatment of the two infectious diseases in China.

The conclusion is based on body weight (BW) and average daily gain (ADG), length index and weight index of small intestine, small intestinal morphology, activity of digestive enzymes in duodenum content, the concentrations of jejunal antioxidant status and cytokines. A completely randomized design with 2 treatments, the control group (CON) and early weaning (EW) group, was utilized. Eight squabs per treatment were sampled at the age of 25 d. The results showed that early weaning reduced BW (P < 0.05), ADG (P < 0.05), ileac length index (P < 0.05), and weight index (P < 0.01). Compared with the CON group, small intestinal morphology was altered in the EW group. Ileac crypt depth (CD) increased significantly (P < 0.01). The villus area was decreased in the duodenum (P < 0.05), jejunum (P < 0.01), and ileum (P < 0.05). The ileac ratio of villus height to crypt depth (VCR) in the EW group was lower than the ileac ratio of villus height to VCR in the CON group (P < 0.01). The activity of trypsin (P < 0.05), sucrase (P < 0.01) and aminopeptidase-N (APN) (P < 0.01) in the duodenum was reduced. Jejunal malondialdehyde (MDA) (P < 0.01) was increased and total superoxide dismutase (T-SOD) (P < 0.01) was reduced significantly. Early weaning decreased the concentrations of interferon-γ (IFN-γ) (P < 0.01), interleukin-4 (IL-4) (P < 0.05) and interleukin-10 (IL-10) (P < 0.01) but induced significant upregulation of interleukin-2 (IL-2) (P < 0.05). In conclusion, our results suggested that early weaning did harm the BW and ADG, intestinal length index and weight index, intestinal morphology, activity of digestive enzymes, and antioxidant and cytokine status.

Abstract
The present study was designed to fabricate a new chitosan-collagen sponge (CCS) for potential wound dressing applications. CCS was fabricated by a 3.0% chitosan mixture with a 1.0% type I collagen (7:3(w/w)) through freeze-drying. Then the dressing was prepared to evaluate its properties through a series of tests. The new-made dressing demonstrated its safety toward NIH3T3 cells. Furthermore, the CCS showed the significant surround inhibition zone than empty controls inoculated by E. coli and S. aureus. Moreover, the moisture rates of CCS were increased more rapidly than the collagen and blank sponge groups. The results revealed that the CCS had the characteristics of nontoxicity, biocompatibility, good antibacterial activity, and water retention. We used a full-thickness excisional wound healing model to evaluate the in vivo efficacy of the new dressing. The results showed remarkable healing at 14th day post-operation compared with injuries treated with collagen only as a negative control in addition to chitosan only. Our results suggest that the chitosan-collagen wound dressing were identified as a new promising candidate for further wound application.

Abstract
The healing process of diabetic wounds is typically disordered and prolonged and requires both angiogenesis and epithelialization. Disruptions of the endogenous electric fields (EFs) may lead to disordered cell migration. Electrical stimulation (ES) that mimics endogenous EFs is a promising method in treating diabetic wounds; however, a microenvironment that facilitates cell migration and a convenient means that can be used to apply ES are also required. Chitosan-Vaseline® gauze (CVG) has been identified to facilitate wound healing; it also promotes moisture retention and immune regulation and has antibacterial activity. For this study, we created a wound dressing using CVG together with a flexible ES device and further evaluated its potential as a treatment for diabetic wounds. We found that high voltage monophasic pulsed current (HVMPC) promoted healing of diabetic wounds in vivo. In studies carried out in vitro, we found that HVMPC promoted the proliferation and migration of human umbilical vein endothelial cells (HUVECs) by activating PI3K/Akt and ERK1/2 signaling. Overall, we determined that the flexible ES-chitosan dressing may promoted healing of diabetic wounds by accelerating angiogenesis, enhancing epithelialization, and inhibiting scar formation. These findings provide support for the ongoing development of this multidisciplinary product for the care and treatment of diabetic wounds.

Abstract
The underlying mechanisms of wound healing are complex but inflammation is one of the determining factors. Besides its traditional role in combating against infection upon injury, the characteristics and magnitude of inflammation have dramatic impacts on the pathogenesis of scar. Keloids and hypertrophic scars are pathological scars that result from aberrant wound healing. They are characterized by continuous local inflammation and excessive collagen deposition. In this review, we aim at discussing how dysregulated inflammation contributes to the pathogenesis of scar formation. Immune cells, soluble inflammatory mediators, and the related intracellular signal transduction pathways are our three subtopics encompassing the events occurring in inflammation associated with scar formation. In the end, we enumerate the current and potential medicines and therapeutics for suppressing inflammation and limiting progression to scar. Understanding the initiation, progression, and resolution of inflammation will provide insights into the mechanisms of scar formation and is useful for developing effective treatments.

Abstract
Fractional CO2 laser is a good option for treating acne scars. However, the clinical efficacy of this treatment modality requires further evidence. To perform a meta-analysis to assess clinical improvements in acne scars with fractional CO2 laser and non-CO2 laser therapies. Databases (PubMed, Embase, Cochrane Library) were searched using the search strategy to identify eligible studies. All statistical analyses were performed using the Review Manager 5.0, and a meta-analysis was conducted to assess the effects of fractional CO2 laser used as a treatment for acne scars. Eight studies were included for further analysis. There was no significant difference between fractional CO2 laser and non-CO2 laser therapies in terms of clinical improvement, observer assessment (P = .19), patient assessment (P = .91), and incidence of post-inflammatory hyperpigmentation (P = .69). The subgroup analyses showed that the duration of follow-up had little effect on the evaluation of treatment effect. The efficacy of fractional CO2 laser therapy in acne scars appeared to be equal to that of non-CO2 laser therapies. More well designed randomized controlled trials and more credible and standard evaluation criteria are needed, and the efficiency of combination therapy requires further analysis.

Abstract
Objective: Platelet-derived growth factor alpha (PDGFRA) mutations are respectively rare in gastrointestinal stromal tumors (GIST). Most GIST with PDGFRA exon 18 mutations including D842V mutation are highly resistant to imatinib. The treatment of GIST harboring PDGFRA primary drug-resistant mutation is a major challenge. This article aims to investigate clinicopathologic features of GIST with PDGFRA-D842V mutation and the efficacy of comprehensive treatment, providing a reference for clinical practice. Methods: A retrospective cohort study was conducted to collect the clinicopathological and follow-up data of patients with GIST harboring PDGFRA mutation who were diagnosed and treated in the GIST Clinic of Renji Hospital from January 2005 to May 2020. According to the mutation site, the enrolled patients were divided into D842V mutation group and non-D842V mutation group. The differences of clinicopathologic characteristics between the two groups were compared. Furthermore, overall survival and prognostic factors were analyzed. Results: A total of 71 patients with PDGFRA-mutant GIST were included in this study, including 47 cases of D842V mutation (66.2%) and 24 cases of non-D842V mutation (33.8%). There were 28 male patients and 19 female patients in D842V mutation group, with a median age of 60 (36-82) years. There were 16 male patients and 8 female patients in non-D842V mutation group, with a median age of 62 (30-81) years. There were no significant differences in age, gender, primary location, surgical procedure, tumor size, mitotic count, expression of CD117 and DOG1, Ki-67 proliferation index and modified NIH grade between the two groups (all P>0.05). The positive rate of CD34 was 89.4% (42/47) and 62.5% (15/24) in the D842V mutation group and the non-D842V mutation group, respectively, with a statistically significant difference (χ(2)=5.644, P=0.018). Among all the cases, 66 cases underwent R0 resection without preoperative treatment; two cases underwent emergency operation with R1 resection because of tumor rupture; 2 cases were not operated after the pathological and mutation types were confirmed by biopsy (one case received avapritinib treatment and obtain partial remission). One case was diagnosed as wild-type GIST per needle biopsy in another institute, and underwent R0 resection after preoperative imatinib treatment for 6 months. After surgery, 5 high-risk GIST patients with D842V mutation and 5 high-risk GIST patients with non-D842V mutation were treated with imatinib for more than one year. The median follow-up time was 37 (1-153) months. As of the last follow-up among the patients who received R0 resection, 4 patients with D842V mutation had relapse, of whom 1 was in the period of imatinib administration, and the 3-year relapse-free survival rate was 94.2%; none of the patients with non-D842V mutation had relapse. There was no statistically significant difference in relapse-free surivval between two groups (P=0.233). Univariate analysis revealed that mitotic count (P=0.002), Ki-67 proliferation index (P<0.001) and modified NIH grade (P=0.025) were the factors associated with relapse-free survival of patients with D842V mutation after R0 resection (all P<0.05). However, the above factros were not testified as independant prognostic facors in multivariate Cox analysis (all P<0.05). Conclusion: Clinicopathologic features and the efficacy of radical resection in patients with PDGFRA-D842V mutation are similar to those in patients with non-D842V mutation.

Abstract
PURPOSE To investigate the accuracy and efficiency of bedside ultrasonography application performed by certified sonographer in emergency patients with blunt abdominal trauma. METHODS The study was carried out from 2017 to 2019. Findings in operations or on computed tomography (CT) were used as references to evaluate the accuracy of bedside abdominal ultrasonography. The time needed for bedside abdominal ultrasonography or CT examination was collected separately to evaluate the efficiency of bedside abdominal ultrasonography application. RESULTS Bedside abdominal ultrasonography was performed in 106 patients with blunt abdominal trauma, of which 71 critical patients received surgery. The overall diagnostic accordance rate was 88.68%. The diagnostic accordance rate for liver injury, spleen injury, kidney injury, gut perforation, retroperitoneal hematoma and multiple abdominal organ injury were 100%, 94.73%, 94.12%, 20.00%, 100% and 81.48%, respectively. Among the 71 critical patients, the diagnostic accordance rate was 94.37%, in which the diagnostic accordance rate for liver injury, spleen injury, kidney injury, gut perforation and multiple abdominal organ injury were 100%, 100%, 100%, 20.00% and 100%. The mean time for imaging examination of bedside abdominal ultrasonography was longer than that for CT scan (4.45 ± 1.63 vs. 2.38 ± 1.19) min; however, the mean waiting time before examination (7.37 ± 2.01 vs. 16.42 ± 6.37) min, the time to make a diagnostic report (6.42 ± 3.35 vs. 36.26 ± 13.33) min, and the overall time (17.24 ± 2.33 vs. 55.06 ± 6.96) min were shorter for bedside abdominal ultrasonography than for CT scan. CONCLUSION Bedside ultrasonography application provides both efficiency and reliability for the assessment of blunt abdominal trauma. Especially for patients with free peritoneal effusion and critical patients, bedside ultrasonography has been proved obvious advantageous. However, for negative bedside ultrasonography patients with blunt abdominal trauma, we recommend further abdominal CT scan or serial ultrasonography scans subsequently.

Abstract
The diagnosis and treatment of gastrointestinal stromal tumor (GIST) is getting more and more standardized. In the last two decades, due to the elucidation of molecular mechanism of tumorigenesis, as well as the effectiveness of tyrosine kinase inhibitors, GIST has become well-known as one of the most classical models of targeted therapy on solid tumors in the precision medicine era. The National Comprehensive Cancer Network (NCCN) issued the latest version of clinical practice guideline on soft tissue sarcoma in February 2020. Compared with previous versions, the new version of the guideline highlighted the treatment recommendations of avapritinib, which further promoted the precise targeted treatment of GIST.

Abstract
We demonstrate with morphological characters that the species Pterostyrax burmanicus W.W.Sm. & Farrer and Parastyrax macrophyllus C.Y.Wu & K.M.Feng (Styracaceae) are best placed in the genus Rehderodendron Hu. Rehderodendron burmanicum (W.W.Sm. & Farrer) W.Y.Zhao, P.W.Fritsch & W.B.Liao, comb. nov. and Rehderodendron macrophyllum (C.Y.Wu & K.M.Feng) W.Y.Zhao, P.W.Fritsch & W.B.Liao, comb. nov., are created. We also provide a lectotype for R. macrophyllum. These revisions result in the reduction of Pterostyrax Siebold & Zucc. to three species and this genus is no longer considered to be documented from Myanmar. Further, Parastyrax W.W.Sm. becomes a monotypic genus comprising only P. lacei (W.W.Sm.) W.W.Sm., distributed in Kachin State, northeast Myanmar and Yunnan Province, south-western China.

Abstract
Studies on the effectiveness and mechanisms of reducing scar formation by interfering with the renin-angiotensin-aldosterone-system (RAAS) have been demonstrated in animals, but not in humans due to the lack of clinical support. Our aim was to investigate whether angiotensin-converting enzyme inhibitor (ACEI) and angiotensin II type 1 receptor blocker (ARB) could inhibit scar formation in humans. Thus, an observational and hypothesis-generating study using a designed questionnaire was carried out. A total of 347 patients with postoperative scars secondary to thyroid tumours were enrolled. They were divided into four groups: ACEI group, ARB group, other antihypertensive drugs control group and blank control group according to the administration of antihypertensive drugs. The width of scar was measured, and the Scar Cosmesis Assessment and Rating (SCAR) Scale was filled out. Results showed that patients of ACEI group (mean scar width 1.60 mm) and ARB group (mean scar width 1.57 mm) formed smaller scars than those of other antihypertensive drugs control group (mean scar width 2.09 mm) and blank control group (mean scar width 2.0 mm). Oral administration of ACEI and ARB may be associated with better post-surgical scar formation in humans. These two kinds of antihypertensive drugs may be active components of anti-scar medicine.

Abstract
Wound dressings are always needed after skin injury; however, most of the dressings still leave room for improvement. Here, we would like to develop an effective dressing with the ability to improve wound healing. A chitosan-Vaseline gauze (CVG) dressing was developed by coating the chitosan mixture and Vaseline on sterile gauze with subsequent drying. Infrared spectroscopy and electron microscopy were used to investigate the miscibility and structure of the dressing. The cytotoxicity and antibacterial nature were evaluated in vitro. The studies of water retention rate, wound healing, and tissue compatibility were carried out over a period of 14 days on full-thickness skin wounds of male Sprague-Dawley rats. It was observed that the CVG dressing demonstrated functional structure by miscibility, non-cytotoxicity, and good antibacterial effects against both Gram-positive and Gram-negative bacteria. The water retention rate incresased up to 25% after applying CVG for 3 hours. Besides, CVG treatment increased angiogenesis and improved microvascular density in wounds. The wounds treated with CVG showed size deduction with new collagen aggregations similar to those in the normal dermis. All the aforementioned results suggest that CVG dressing could be a promising candidate for wound treatment.

Abstract
Background: Long noncoding RNA (lncRNA) LUADT1 is a known oncogenic lncRNA in lung cancer. This study aimed to explore the roles of LUADT1 in melanoma. Materials and Methods: Sixty pairs of melanoma and nontumor tissues were obtained from 60 melanoma patients (37 men and 23 women, 38-68 years, 52.1 ± 4.9 years) at the First Affiliated Hospital of Zhejiang University School of Medicine. Gene expression was analyzed by quantitative polymerase chain reaction and western blot. Cell transfections were performed to analyze gene expression. Results: We found that LUADT1 was upregulated in melanoma and high levels of LUADT1 predicted poor survival. RNA interaction prediction showed that LUADT1 can form base pairing with miR-28-5p. In melanoma cells, LUADT1 overexpression mediated the upregulated Ras-related protein Rap-1b (RAP1B). Cell proliferation assay showed that LUADT1 and RAP1B overexpression mediated the increased proliferation rate of melanoma cells. In addition, miR-28-5p overexpression played opposite roles attenuating the effects of LUADT1 overexpression on both RAP1B expression and cancer cell proliferation. Conclusions: LUADT1 in melanoma and may sponge miR-28-5p to upregulate RAP1B, thereby promoting cancer cell proliferation.

Abstract
BACKGROUND AND OBJECTIVES Traditional surgical excision for a sebaceous cyst can completely eradicate the cyst, but the surgical processes are relatively complicated and may cause obvious scarring. Some patients are reluctant to choose this method because of the inconvenient procedures and the risk of conspicuous scarring, especially in esthetically important areas. We present a simple treatment method to prevent formation of a conspicuous scar. STUDY DESIGN/MATERIALS AND METHODS First, the cyst wall was pre-separated from the surrounding tissues by injecting a large volume of anesthetic around the cyst. Then, the cyst contents were removed through a small hole created by using a CO2 laser on the skin surface, which adhered closely to the cyst. Finally, the cyst wall was removed using a hemostat that clamps it at the base. Between August 2017 and July 2019, 32 patients with 33 sebaceous cysts (12 infected and 21 uninfected) were treated by this method to remove the cyst contents and cyst wall. Mean operative time, complications, and patient satisfaction were evaluated. RESULTS All patients were satisfied with the good esthetic outcome and the simplicity of the surgical procedure. Only two of the 33 cysts (6.0%) recurred 2 and 3 months postoperatively, including 0 of 21 uninfected cysts (0.0%) and 2 of 12 infected cysts (16.7%). No complications were found during the follow-up period. The mean operation time was 13 ± 2.1 minutes. CONCLUSIONS CO2 laser punch-assisted surgery was associated with minimal scarring and high patient satisfaction. With acceptable recurrence rates, it is a convenient, effective and minimally-invasive treatment option for sebaceous cysts. Lasers Surg. Med. © 2020 Wiley Periodicals, Inc.

Abstract
Wound scarring remains a major challenge for plastic surgeons. Transforming growth factor (TGF)-β plays a key role in the process of scar formation. Previous studies have demonstrated that truncated TGF-β type II receptor (t-TGF-βRII) is unable to continue signal transduction but is still capable of binding to TGF-β, thereby blocking the TGF-β signaling pathway. Hepatocyte growth factor (HGF) is a multifunctional growth factor that promotes tissue regeneration and wound healing. Theoretically, the combination of HGF and t-TGF-βRII would be expected to exert a synergistic effect on promoting wound healing and reducing collagen formation. In the present study, lentivirus-mediated transfection of the two genes (t-TGF-βRII/HGF) into fibroblasts in vitro and in a rat model in vivo was used. The results demonstrated that the expression of t-TGF-βRII and HGF in NIH-3T3 cells was successfully induced. The expression of both molecules significantly reduced collagen I and III expression, and also inhibited fibroblast proliferation. Furthermore, histological examination and scar quantification revealed less scarring in the experimental wound in a rat model. Moreover, on macroscopic inspection, the experimental wound exhibited less visible scarring compared with the control. Therefore, the present study demonstrated that the combination gene therapy of t-TGF-βRII and HGF promoted wound healing, with less scarring and more epithelial tissue formation, not only by suppressing the overgrowth of collagen due to its antifibrotic effect, but also by promoting tissue regeneration.

Abstract
Dressings are necessary during the process of wound healing. Since the early 1980s, several types of wound dressings have been produced, but they cannot always take into account some effects include antibacterial effect, wound healing promotion, and other properties. In this study, we would like to develop an effective dressing with the above properties, especially accelerating wound healing effect. A chitosan-calcium alginate dressing (CCAD) was developed by coating mixture of chitosan with high-low molecular weight on calcium alginate dressing (CAD). We investigated the structural characteristics of CCAD with Fourier-transform infrared spectroscopy (FTIR) and electron microscopy. The cytotoxicity and antibacterial property were evaluated in vitro using CCK-8 and inhibition zone method. Moisture retention was tested on the skin of Sprague-Dawley (SD) rats, and wound healing studies were performed on a full-thickness skin wound model in SD rats. CCAD showed good moisturizing and antibacterial properties with no cytotoxicity. CCAD could inhibit inflammation by decreasing IL-6, and it could also promote angiogenesis by increasing VEGF, resulting in better wound healing than CAD. CCAD is a better choice in wound care due to its antibacterial property, biocompatibility, moisture retention, healing promotion, and non-cytotoxicity characteristics.

Abstract
Saxifraga damingshanensis (Saxifragaceae), a new species from Damingshan Nature Reserve in Guangxi Province, is described and illustrated. A morphological comparison between the new species and its putative relatives, S. mengtzeana and S. luoxiaoensis, is presented. The new species is morphologically similar to S. mengtzeana, but it can be easily distinguished by its non-peltate leaf, both surfaces of mature leaf blade covered with white glandular trichome, petals 3-veined and margin entire. Phylogenetic analysis, based on two chloroplast DNA regions (matK and psbA-trnH), confirmed that the new species belongs to S. sect. Irregulares. The new species is currently only known from Damingshan, Guangxi and we assign it an IUCN Red List preliminary status as Data Deficient.

Abstract
Objective: To investigate the significance of monitoring imatinib mesylate (IM) plasma concentrations in patients with gastrointestinal stromal tumor (GIST). Methods: A retrospective descriptive study was carried out. Inclusion criteria: (1) patients with GIST confirmed by postoperative pathology or puncture pathology receiving maintenance therapy of IM; (2) administration of same dose of IM for at least 4 weeks (achieving steady - state plasma concentration). Patients who had severe organ dysfunction, received IM generics, or received IM simultaneously with other drugs significantly affecting IM pharmacokinetic were excluded. A total of 185 patients at the GIST Clinic of Renji Hospital, Shanghai Jiaotong University School of Medicine from August 2018 to May 2019 were enrolled, including 114 males (61.6%) and 71 females (38.4%) with a median age of 60 years old (range, 30-89 years), and 63 advanced cases. Patients receiving preoperative or postoperative adjuvant therapy were given IM 400 mg QD; patients with KIT exon 9 mutation or with disease progression during IM 400 mg QD treatment were given IM 600 mg QD. If the patient had adverse reactions such as myelosuppression during the medication, IM would be reduced or given BID per day. The peripheral venous blood was collected (22 to 24 hours after the last dose for patients who took IM QD and 2 hours before the first dose per day for those who took IM BID). IM plasma concentration was measured through high performance liquid chromatography coupled with tandem mass spectrometry (HPLC-MS/MS). Correlation analysis between IM plasma concentration results and clinical data was performed using linear regression analysis. Results: A total of 241 stable blood samples of IM plasma concentration from 185 patients were finally collected. The IM plasma concentrations were significantly different between the doses of 300 mg/d and 400 mg/d [(942.4±433.5) μg/L vs. (1340.0±500.1) μg/L, t=6.317, P<0.001], and between 400 mg/d and 600 mg/d [(1340.0±500.1) μg/L vs. (2188.0±875.5) μg/L, t=3.557, P=0.004]. Among the blood samples of 57 patients receiving IM 300 mg/d, the IM plasma concentration of the advanced patients was significantly lower than that of the non-advanced patients [(795.6±225.8) μg/L vs. (992.2±484.4) μg/L, t=2.088, P=0.042]. Among the 137 blood samples of patients receiving IM 400 mg/d, the IM plasma concentration was higher in patients aged >60 years than those aged ≤60 years [(1461.0±595.3) μg/L vs. (1240.0±380.9) μg/L, t=2.528, P=0.013] and the IM plasma concentration of cases with diarrhea was significantly lower than that of those without diarrhea [(745.8±249.6) μg/L vs. (1382.0±486.9) μg/L, t=6.794, P<0.001]. Gender, primary location, surgical procedure, mutated gene, mutation type, or time of administration was associated with IM plasma concentration no matter in patients taking IM doses of 400 mg/d or 300 mg/d (all P>0.05). Regression analysis showed that body mass (P=0.004 and P=0.019), body mass index (P=0.016 and P=0.042), and body surface area (P=0.007 and P=0.028) were all negatively correlated with IM plasma concentrations in patients taking IM doses of 300 mg/d and 400 mg/d. Within the 137 patients who received a fixed oral dose of 400 mg/d IM, 17 patients received oral 200 mg BID, whose IM plasma drug concentration was not significantly different compared with that of 120 patients who received 400 mg IM QD [(1488.0±408.3) μg/L vs. (1319.0±509.7) μg/L, t=1.307, P=0.193]. Conclusions: Monitoring IM plasma concentration is significant throughout the whole process of management of GIST patients receiving IM treatment. In particular, regular monitoring IM plasma concentration and developing appropriate treatment strategies can bring better therapeutic benefits for patients with low doses, diarrhea, advanced condition and older age.

Abstract
Apple fruit spot disease has caused serious economic losses for years in China since the widespread application of fruit bagging in production. Although the three genera Trichothecium, Alternaria, and Acremonium have been reported to be the causal agents, studies on the disease etiology and pathogen biology are still sparse. Here, we report characterization of eight fungal isolates from lesions on 126 symptomatic fruit samples collected in Shaanxi Province, China. Pathogenicity of the isolates was assessed. DNA sequences were obtained at four loci, including D1/D2 domains of the large-subunit nrRNA gene, internal transcribed spacer regions 1 and 2, 5.8S nrDAN gene, a fragment of the actin gene, and a fragment of the β-tubulin. Based on phylogenetic analysis and morphological features, three new species were found: Acremonium mali, Sarocladium liquanensis, and Sarocladium mali. In addition, we made the first report of Sarocladium terricola as a plant pathogen. Temperature and moisture significantly affected in vitro conidial germination of five Acremonium-like species, and their impact on infection of apple fruit was tested using Acremonium sclerotigenum. Conidia of five species germinated from 15 to 35°C in free water; four of the species had optimum temperature around 25°C, whereas conidia of S. terricola had an optimum temperature of 30°C. Conidial germination rate increased as relative humidity (RH) increased. The five isolates had relatively high conidial germination rates at RH > 97%, with a significant decline at 95% RH. Incidence of infection also increased in proportion to RH. In free water, conidial germination was relatively unaffected by temperature.

Abstract
Angiotensin-converting enzyme (ACE) has been found in the pathogenesis of various fibrosis diseases, and ACE inhibitor (ACEI) may affect wound healing and cutaneous fibrosis. However, there is no scientific evidence as to where the ACE is produced during scar formation. Whether it is from the cutaneous tissue or the bone marrow, or both remains unknown. In this study, we investigated the source of ACE using bone marrow transplantation in genetically modified mice, analyzed the inflammatory milieu and some growth factors in the middle of the wound healing period (4 d after the wound was induced). After having deleted the ACE from bone marrow or skin tissue, the wound/scar width in the low-ACE groups were narrower than those in wild-type (WT) controls. Loosely arranged collagen deposition and reduced vessel density were also detected in ACE-deficient mice. Lower ACE levels during scar formation were also accompanied by lower levels of TGF-β1. In the middle of the wound healing period, ACE levels affected the inflammatory cells significantly. In the mice with a deficiency in ACE, the expression of TGF-β1 and TNF-α decreased, but not that of IL-4. Our findings indicate that both bone marrow and skin tissue release ACE during scar formation. Deleting either of them can affect the inflammatory cells and growth factors and reduce the expression of TGF-β1, resulting in a decreased level of scarring.-Fang, Q.-Q., Wang, X.-F., Zhao, W.-Y., Chen, C.-Y., Zhang, M.-X., Shi, B.-H., Zhang, L.-Y., Tan, W.-Q. The source of ACE during scar formation is from both bone marrow and skin tissue.

Abstract
OBJECTIVES To evaluate the feasibility, effectiveness, and safety of computed tomography-assisted auricular cartilage grafting for treating alar base depression secondary to unilateral cleft lip. DESIGN AND SETTING For patients with obvious depression of the alar base, the difference in heights of the alar base and the piriform margin between the cleft side and the noncleft side were measured with computed tomography. If both were >3.0 mm, the cartilage was harvested postauricularly and subdivided into 2 to 4 pieces. A multiple layer graft was inserted under the depressed alar base. The procedure was performed from 2006 to 2013, and the follow-up period was 3 to 15 months. PARTICIPANTS Chinese patients with alar base depression secondary to unilateral cleft lip were selected. INTERVENTION Suture and cartilage graft techniques. MAIN OUTCOMES MEASURES Differences in bilateral alar base heights and piriform apertures. RESULTS There was no wound dehiscence, exposure of bone, or donor site morbidity. The difference in heights in the bilateral alar bases and piriform apertures decreased. There were no obvious scars in any of the cases. CONCLUSIONS This technique has several advantages including ease of operation, minimal trauma, satisfactory outcomes, and useful references for operation provided by computed tomography. It is a superior alternative for reconstruction of secondary alar depression.

Abstract
Angiotensin-converting enzyme inhibitors (ACEIs) can improve the fibrotic processes in many internal organs. Recent studies have shown a relationship between ACEI with cutaneous scar formation, although it has not been confirmed, and the underlying mechanism is unclear. In this study, we cultured mouse NIH 3T3 fibroblasts with different concentrations of ACEI. We measured cell proliferation with a Cell Counting Kit-8 and collagen expression with a Sirius Red Collagen Detection Kit. Flow cytometry and western blotting were used to detect transforming growth factor β1 (TGF-β1) signaling. We also confirmed the potential antifibrotic activity of ACEI in a rat scar model. ACEI reduced fibroblast proliferation, suppressed collagen and TGF-β1 expression, and downregulated the phosphorylation of SMAD2/3 and TAK1, both in vitro and in vivo. A microscopic examination showed that rat scars treated with ramipril or losartan were not only narrower than in the controls, but also displayed enhanced re-epithelialization and neovascularization, and the formation of organized granulation tissue. These data indicate that ACEI inhibits scar formation by suppressing both TGF-β1/SMAD2/3 and TGF-β1/TAK1 pathways, and may have clinical utility in the future.

Abstract
Background: Iron and zinc deficiencies affect human health globally, especially in developing countries. Agronomic biofortification, as a strategy for alleviating these issues, has been focused on small-scale field studies, and not widely applied while lacking of cost-effectiveness analysis (CEA). Objective: We conducted the CEA of agronomic biofortification, expressed as USD per disability-adjusted life years (DALYs) saved, to recommend a cost-effectiveness strategy that can be widely applied. Methods: The DALYs were applied to quantify the health burden due to Fe and/or Zn deficiency and health cost of agronomic biofortification via a single, dual, or triple foliar spray of Fe, Zn, and/or pesticide in 4 (northeast, central China, southeast, and southwest) major Chinese rice-based regions. Results: The current health burden by Fe or Zn malnutrition was 0.45 to 1.45 or 0.14 to 0.84 million DALYs for these 4 regions. Compared to traditional rice diets, the daily Fe and/or Zn intake from Fe and/or Zn-biofortified rice increased, and the health burden of Fe and/or Zn deficiency decreased by 28% and 48%, respectively. The cost of saving 1 DALYs ranged from US$376 to US$4989, US$194 to US$2730, and US$37.6 to US$530.1 for the single, dual, and triple foliar Fe, Zn, and/or pesticide application, respectively, due to a substantial decrease in labor costs by the latter 2 applications. Conclusions: Agronomic biofortification of rice with the triple foliar spray of Fe, Zn, and pesticide is a rapidly effective and cost-effectiveness pathway to alleviate Fe and Zn deficiency for rice-based dietary populations.

Abstract
Soil incubation experiment and pot experiment were carried out to investigate the influence of nano zeolite (NZ) and ordinary zeolite (OZ) on the soil pH, cation exchange capacity, concentration of soil Cd, soil Cd fraction and Cd uptake by Chinese cabbage when exposed to different Cd pollution levels(1, 5, 10 and 15 mg·kg-1). The results of soil incubation experiment showed that the nano zeolite and ordinary zeolite dose(5, 10 and 20 g·kg-1) increased the soil pH and cation exchange capacity, and decreased the concentration of soil exchangeable Cd, while increased the concentration of Cd in carbonate, Fe-Mn oxide, organic matter and residual fraction. The lowest EX-Cd was observed in the high nano zeolite (20 g·kg-1) treatment. The soil pH and cation exchange capacity was extremely negatively correlated with the concentration of soil exchangeable Cd(P<0.01),and extremely positively correlated with the concentration of soil Fe-Mn oxide Cd(P<0.01). The results of pot experiment showed that the FDC of exchangeable Cd in soil decreased by 6.4%-63.2%, and the FDC of water-extractable and ethnol-extractable Cd in Chinese cabbage decreased by 2.1%-56% and 11.8%-100% with zeolite application, respectively. Moreover, the reduction effect of nano zeolite on Cd concentration in soil and plant was better than that of ordinary zeolite. The FDC of Cd fraction in shoot of Chinese cabbage showed correlation with the FDC of carbonate Cd and organic matter Cd in soil(P<0.05) when exposed to 1 mg·kg-1 Cd pollution. Moreover, correlation was also found in the FDC of organic matter Cd and residual Cd in soil(P<0.05) under 5 mg·kg-1 Cd pollution.

Abstract
Pot experiment was carried out to investigate the influence of nano zeolite (NZ) and ordinary zeolite (OZ) on the growth, activities of antioxidant enzyme, Cd fraction and Cd concentration in two varieties of Chinese cabbage. The results showed that the activities of SOD, CAT and POD in the shoot and root of two varieties increased, and the dry weight of shoot and the total dry weight of Chinese cabbage increased by 4.5%-96.5% and 3.4%-88.4%, respectively. The application of zeolite effectively reduced the Cd concentration of shoot and root in the two varieties of Chinese cabbage, and the reduction range increased with the increase of the application amount of zeolite. Under the low Cd condition (1mg·kg-1 Cd), the Cd concentration of edible parts (shoots) in SD4 variety and XJC3 variety decreased by 1.0%-75.0% and 19.5%-68.9% (except the Cd1+OZ5/OZ10 processing), respectively. Under the high Cd condition (5 mg·kg-1 Cd), the Cd concentration of the edible parts (shoots) in SD4 variety and XJC3 variety decreased by 7.2%-53.2%(except Cd5+OZ10 processing) and 0.7%-63.0%, respectively. The Cd concentrations of the edible parts (shoots) in tow varieties of Chinese cabbage in the nano zeolite treatments decreased by 10.5%-65.7% compared with the ordinary zeolite treatments. In Cd contaminated soils (1 mg·kg-1 and 5 mg·kg-1 Cd),) the total extraction amount of Cd in the edible parts (shoots) of SD4 variety reduced by 12.4%-68.8% and 13.2%-55.6% (except of Cd5+OZ5 processing), and the total extraction amount of Cd in the edible parts (shoots) of XJC3 variety reduced by 9.4%-71.5% and 3.1%-38.7% (except of Cd1+OZ5 processing), respectively. The application amount of nano zeolite (NZ) and ordinary zeolite (OZ) was more, the reduction range of the total extraction amount of Cd in the edible parts (shoots) of two varieties of Chinese cabbage was greater.

Abstract
OBJECTIVE To investigate adherence and the influence factors among patients who are on antiretrovirus therapy (ART) of 3 provinces in China. METHODS This study selected 18-year-old and older AIDS patients as the survey objects who initiated anti-retrovirus therapy between April and September of 2014 and kept on the treatment for one year in Yunnan,Sichuan,and Hu'nan province. Information of demography, treatment and social support was collected by questionnaires. Adopt SSRS questionnaire to calculate the information of objective support, subjective support and utilization of social support. χ(2) test and logistic regression were performed to examine relationships between factors and adherence. RESULTS A total of 386 patients with medication were investigated. Among them, there were 365 (94.6%) cases who were compliant to the ART, and 357 (92.5%) cases can take their pills on time, and 29 (7.5%) cases take their medication in excess of the prescribed time more than two hours. Social support score was 27.2 ± 7.3, including objective support score (5.6 ± 2.7), subjective support score (16.1 ± 4.8), and utilization of social support (5.5 ± 1.9). Multivariate logistic regression analysis revealed that adherence was significantly associated with the correct cognition of medication (OR (95%CI): 3.24 (1.17-9.00)), the self-awareness of the drug regimen was not complexity (OR (95%CI): 9.34 (3.27-26.68)), taking medication 1 time a day (OR (95%CI): 4.00 (1.35-11.84)), and the batter utilization of social support (OR (95%CI): 1.49 (1.06-2.01)). Married/cohabiting or farmers tend to be nonadherenced, while the OR (95%CI) was 0.24 (0.08-0.67) and 0.23 (0.08-0.69), respectively. CONCLUSION The patients among these provinces were compliant to the ART, and most of them can take their pills on time. The social support score of these patients was lower than normal person. Participants who have correct cognition of medication, thinking their drug regimen was not complexity; Taking medication 1 time a day or have high level of utilization of social support showed a significantly higher level of self-reported adherence.

Abstract
Incubation experiments were carried out to investigate the influence of different nano zeolite(NZ) and ordinary zeolite(OZ) levels(0, 5, 10 and 20 g·kg-1) on the fraction distribution coefficient (FDC) of Cd and soil CEC at different soil pH (4, 5, 6, 7 and 8) when exposed to different cadmium(Cd) levels(1, 5, 10 and 15 mg·kg-1), and pot experiment were carried out to investigate the effects of nano zeolite(NZ) and ordinary zeolite(OZ) on the growth, Cd concentration and Cd accumulation of Chinese cabbage. The results showed that nano zeolite and ordinary zeolite decreased the concentration and FDC of exchangeable Cd (EX-F), and increased the concentration and FDC of carbonate(CAB-F), Fe-Mn oxide(FMO-F), organic matter (OM-F) and residual fraction(RES-F) in incubation experiments. At the end of incubation, the FDC of soil exchangeable Cd decreased from 72.0%-88.0% to 2.4%-10.7%. The decreasing effect of zeolite on the concentration and FDC of exchangeable Cd (EX-F) increased with the increase of zeolite, and the decreasing effect of nano zeolite (NZ) was better than that of ordinary zeolite (OZ). During the culture of 28 d, the concentration of different Cd fractions in soil was in order of EX-F>RES-F>FMO-F>CAB-F>OM-F under different pH conditions. Exchangeable fraction Cd was the dominant fraction of Cd in soil during the whole incubation. Soil CEC had significant negative correlation with soil exchangeable Cd (EX-F) (P<0.01), and significant positive correlation with the concentrations of Fe-Mn oxide(FMO-F) and organic matter (OM-F) in soil(P<0.01). Nano zeolite and ordinary zeolite effectively increased soil CEC, and soil CEC increased with the increase of the pH value of soil in the zeolite treatments. Significant negative correlation was found in soil pH with soil exchangeable Cd (EX-F)(P<0.01). The dry weight of plant tissues in Chinese cabbage increased by 14.3%-131.4% in the presence of nano zeolite(NZ) and ordinary zeolite(OZ), and Cd concentration of shoot and root decreased by 1.0%-75.0% and 3.8%-53.2%, respectively. Higher concentration and accumulation of Cd were observed in XJC3 variety than those in SD 4 variety. Compared with ordinary zeolite (OZ), nano zeolite (NZ) was better in increasing the biomass of Chinese cabbage as well as decreasing accumulation of Cd in Chinese cabbage.

Abstract
The characteristics of scattering due to interface roughness are usually described by the backscattering matrix for reverberation modeling. The backscattering matrix based on the Bass perturbation theory has significant differences from that based on the empirical scattering rule (Lambert's rule), especially at low grazing angles. In a waveguide environment with a point source, it is very difficult to extract the quantitative characteristics of the backscattering matrix at low grazing angles from the experimental data because of the difficulties in acquiring low-grazing-angle scattering data and separating the scattering data between different modes (grazing angles). In contrast, the use of single-mode excitations as sources in shallow-water waveguides enables acquisition of good quality low-grazing-angle scattering data. In this paper, the characteristics of the backscattering matrix were obtained from different single-mode reverberation experiments in shallow-water. The experiments were carried out at different sites during different seasons off the coasts of China. Model-data comparisons were made and the results showed that at low grazing angles (2°-5°), the backscattering matrices based on the Bass perturbation theory were in good agreement with the experimental data, but the backscattering matrices based on Lambert's rule were not.

Abstract
INTRODUCTION A combination of cervical and intradural aneurysm in children in the absence of systemic disorders has previously not been reported. CASE REPORT We report two boys with an identical combination of fusiform cervical internal carotid aneurysm and ipsilaterally located vertebrobasilar aneurysm. They had no history of trauma, they did not display any personal or familial signs of systemic disease, and the testing for collagen disease was negative. The location and appearance of the aneurysms and the identical anatomical disposition in the patients indicated a non-randomly distributed segmental vulnerability. CONCLUSION The cases demonstrate primary morphological signs of a developmental error being expressed in two seemingly separate segments but linked by the hypoglossal artery. It suggests a segmental error related to this embryonic vessel. They also show that few phenotypes are specific for a genotypic disorder and highlight the importance of analysing different etiologies for aneurysm formation and anatomical disposition when taking treatment strategy decisions.

Abstract
SUMMARY Within the group of giant and large aneurysms the subgroup of the so-called "partially thrombosed" aneurysms can be differentiated according to clinical and neuroimaging findings. The present study was carried out to determine the site of bleeding of these aneurysms and what implications concerning their pathomechanism can be drawn from these findings. Twenty patients aged two to 77 (mean 44) years who exhibited a partially thrombosed aneurysm that had recently bled were included. Images (MRI including T1 pre- and postcontrast and T2 weighted images in multiple planes, CT and digital subtraction angiography) and patients' charts were reviewed. MRI showed an onion-skin appearance of the thrombus in 19 patients, rim enhancement of the aneurysm wall (either partial or complete) in 17, and a perifocal edema in 16 patients. The acute hemorrhage was typically crescent-shaped and located at the periphery of the aneurysm, distant from the perfused lumen of the aneurysm within the thrombosed part of the aneurysm. The current denomination "partially thrombosed" intracranial arterial aneurysms leads to the presumption that thrombus is present endoluminal whereas in fact the site of hemorrhage is within the vessel wall. A more accurate nomination would, therefore, be "aneurysms with intramural hemorrhage". The enhancing wall and the edematous reaction of the adjacent brain parenchyma might be a sign for an inflammatory pathomechanism which is reinforced by histological and pathophysiological studies. This disease should be regarded as a clinical entity separate from saccular or non-thrombosed giant or large aneurysms.

Abstract
INTRODUCTION Haemorrhagic intracranial vertebrobasilar dissection is an uncommon cause of nontraumatic subarachnoid haemorrhage (SAH) and accounts for only 1-10% of non-traumatic SAH. Treatment in the acute phase is considered to be essential because of the high risk of rebleeding and the consequent unfavourable outcome. However, the location, the potential for involvement of eloquent vessels and the histopathological characteristics of the vessel wall make treatment demanding from both a technical and anatomical point of view. We report our experience in the management of this disease. PATIENTS AND TREATMENTS: From 1989 to June 2006, we managed 21 patients with spontaneous haemorrhagic dissection located in the intracranial vertebrobasilar system, 13 patients were treated using an endovascular approach, 1 by surgical clipping, and 7 were managed conservatively. RESULTS Among the 13 patients treated endovascularly, 7 underwent proximal occlusion, 4 underwent parent artery embolization at the site of dissection, and 2 underwent endovascular trapping. Severe, treatment-related complications due to dislodgement of the thrombus during the procedure occurred in 1 patient, who then died from brainstem ischaemia. One patient died from severe pneumonia and one patient was left disabled from vasospastic ischaemia resulting from severe initial SAH. The remaining 10 patients had satisfactory outcomes: none rebled after treatment and when discharged they had Karnovsky scores of 80-100. Of the 7 conservatively treated patients, three died of rebleeding and four were discharged with Karnovsky scores of 50-100. One patient, who was treated surgically, was discharged with a Karnovsky of 90. CONCLUSION The high rate of rebleeding and consequent mortality among the patients treated conservatively argues for treatment in the acute phase. Treatment should be guided by each patient's angiomorphology, clinical condition and the experience of the neurosurgical/neuroradiological team. Options include endovascular or surgical trapping of the dissection and proximal occlusion and embolisation of the parent artery at the site of the dissection.
