Abstract
Objective: To investigate the effect and satisfaction of using the postauricular tongue-shaped flap combined with deep fascia suspension in correcting severe cup ear malformation. Methods: Between August 2018 and November 2019, nine cases (10 ears) of Tanzer type Ⅲ severe cup ear malformation were treated with postauricular tongue-shaped flap combined with deep fascia suspension in this study. Results: Nine cases primary healed without hematoma, infection or skin necrosis, except one case with postoperative incision dehiscence. The cup ear deformity was significantly improved after the operation, the helix was intact, and the anti-helix was visible. The length, width, and circumference of the auricle were significantly enlarged three months following surgeries. There were no other complications except 1 patient recurrence 12 months after surgery. The patients were highly satisfied with the results of the surgery. Conclusions: Although the aesthctic of the reconstructed auricle is insufficient, this new technology makes full use of the autologous auricle tissue to correct severe cup ear malformation with good results.

Abstract
BACKGROUND Solitary fibrous tumors (SFTs) occurring in the parapharyngeal space are rare, and their final diagnosis depends on pathological and immunohistochemical analyses. Once the tumor is diagnosed, complete resection and regular postoperative follow-up are required.
CASE SUMMARY A 40-year-old male patient with a right parotid gland mass discovered 8 years ago was admitted to hospital. The mass showed no tenderness or local skin redness. Imaging was carried out as the patient had stable vital signs and showed that the mass was a dumbbell-shaped tumor comprising a superficial tumor approximately 5 cm long and 3 cm wide in size that compressed the right parotid gland and a deep tumor located in the right parapharyngeal space approximately 4.5 cm long and 2.5 cm wide in size. Both tumors were connected in the middle. Prior to surgery, the tumors were considered to be parapharyngeal schwannomas. During surgical dissection, the tumors were found to be smooth and tough, without obvious adhesion to the surrounding tissues. The tumors were revealed to be a SFT following postoperative pathological analysis.
CONCLUSION SFTs in the parapharyngeal space are rarely reported, and complete resection of such tumor is recommended. Adjuvant chemoradiotherapy is used in patients with extensive tumor invasion to lower the recurrence rate. Postoperative long-term follow-up is required.

Effects of physical forms of starter feed on growth, nutrient digestibility, gastrointestinal enzyme activity, and morphology of pre- and post-weaning lambs. Animal 2020; 15:100044. [PMID: 33516036 DOI: 10.1016/j.animal.2020.100044] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2019] [Revised: 07/26/2020] [Accepted: 08/03/2020] [Indexed: 11/27/2022] Open
Abstract
The physical form of starter feed may affect the gastrointestinal development and the performance of ruminant. However, little information is available on how changes in the physical forms of starter feed influence the performance of lambs, especially during the pre- and post-weaning periods. The aim of this study was to investigate the effects of different physical forms of starter feeds on growth performance, nutrient digestibility, gastrointestinal enzyme activity, and morphology of pre- and post-weaning lambs. Twenty-four 8-day-old male Hu lamb (5.04 ± 0.75 kg BW) were randomly assigned to one of two dietary treatments: 1) a pelleted starter (PS) feed and 2) a textured starter (TS) feed, which included coarse mashed steam-flaked corn. From eight to thirty-five days of age (pre-weaning), the lambs were bottle-fed milk replacer (MR) at 2% of BW measured on day 8. All lambs were weaned at day 35 when feeding of MR was stopped. Six lambs for each treatment were euthanized at 21 or 42 days of age for sampling. The following results are obtained by variance analysis: TS lambs had a greater (P < 0.05) final BW, higher apparent digestibility of starch and ether extract, activities of α-amylase pre- or post-weaning, and higher (P < 0.05) average dry matter intake and lipase post-weaning in small intestine contents and had a trend of significantly higher average daily gain post-weaning (P = 0.07). Rumen development analysis of TS lambs showed a significantly higher (P < 0.05) relative weight of rumen post-weaning, greater papillae length, increased circular and layered muscle, increased sectional area pre- and post-weaning, and increased rumen papillae width post-weaning. Textured starter treatment increased the villus height and villus width (except jejunum pre-weaning) of the whole small intestine and villus height to crypt depth ratio of jejunum and ileum during the whole period and tended to increase the relative weight of the rumen pre-weaning (P = 0.07). The results indicated that TS feeding is more beneficial to lambs over the weaning transition than PS in promoting gastrointestinal development, intestinal enzyme activities, nutrient digestibility, and growth performance. The findings provide new insights into the selection of physical forms of starter feeds in lamb production. Further research with more animals and female lambs is needed to obtain a more complete conclusion.

Abstract
Abstract Objective To estimate sex based on patella measurements of Sichuan Han population by computed tomography three-dimensional volume reconstruction technique, and to explore the application value of patella in sex estimation. Methods CT three-dimensional volume reconstruction images of patella of 250 individuals were collected, the four measurement indicators including patellar length, patellar width, patellar thickness, and patellar volume were measured. The t-test was used to determine measurement indicators with sex differences. Fisher discriminant analysis was used to establish the sex discriminant function and the prediction accuracy was calculated by leave-one-out cross validation. Results The sex differences of the four measurement indicators had a statistical significance (P<0.05). The accuracy rate of the univariate discriminant function established by the patellar length was the highest (82.0%). The accuracy rates of the all indicators discriminant function and the stepwise discriminant function were 80.4% and 81.6%, respectively. Conclusion It is feasible and accurate to estimate sex of Sichuan Han population by patella measurements with CT three-dimensional volume reconstruction technique. The method may be used as an alternative for sex estimation of Sichuan Han population when other bones with higher accuracy are not available.

Abstract
PURPOSE Docosahexaenoic acid (DHA) plays an essential role in brain, and its status is dependent on dietary intakes. School-aged children in rural China, who consume diets low in omega-3 polyunsaturated fatty acids, may benefit from DHA supplementation. Therefore, this trial was performed to examine the effect of 6-month DHA supplementation on executive functions (EFs) among healthy school-aged children in rural China. METHODS A randomized, double-blind, placebo-controlled trial was conducted among 106 primary school children aged 7-12 years in rural China. Participants were randomized to receive either 300 mg/d DHA or placebo for 6 months. EFs including working memory and cognitive flexibility were evaluated at baseline, at 3 months and at 6 months, using Digit Span Backwards and Wisconsin card sorting test, respectively. Socio-demographic data were collected at baseline, and erythrocyte membrane fatty acids and serum neurotransmitters were measured at baseline and after 6-month intervention. RESULTS Ninety-four children (88.7%) completed the study according to the protocol. Changes in erythrocyte membrane fatty acids indicated good compliance of the participants. There was no significant intervention effect on serum neurotransmitters. In two-factor ANCOVA, both groups showed a significant improvement in the Digit Span Backwards and the Wisconsin card sorting test from baseline to endpoint. However, no significant intervention effect was found on any EF scores. Linear regression analysis suggested no significant association between changes in erythrocyte DHA level with changes in any EF scores. CONCLUSIONS Supplementation with 300 mg/d DHA for 6 months had no benefit on EFs including working memory and cognitive flexibility among healthy school-aged children. This trial was registered at clinicaltrials.gov as NCT02308930 on December 5, 2014.

Abstract
Objective: To investigate the feasibility and safety of minimally invasive radical prostatectomy for prostate cancer patients without preoperative prostate biopsy in the new era of the continuous development of comprehensive new imaging diagnostic mode and minimally invasive surgery technology. Methods: From August 2018 to October 2019, 17 patients with prostate cancer were enrolled in this study in the Cancer Hospital, Chinese Academy of Medical Sciences. All patients were highly suspected of prostate cancer by PSMA-PET/CT-based imaging diagnostic techniques and underwent 3D laparoscopic radical prostatectomy without prostate biopsy. The perioperative data, postoperative pathology, postoperative complications and follow-up results were recorded and analyzed. Results: The average age of 17 patients with prostate cancer was (65±7) years. The body mass index (BMI) average was (24.4±3.0) kg/m(2). The American Society of Anesthesiologists (ASA) score was 1 (1-2) and the Charlson comorbidity index (CCI) score was 1 (0-4). The preoperative value of PSA was (19±11) μg/L. The PSMA PET/CT showed abnormally high expression foci and the great possibility of prostate cancer for all the 17 patients. Prostate puncture biopsy: the results of prostate biopsy were negative in 3 cases. The digital rectal examination found that the prostate volume was Ⅰ or Ⅱ degree large, 10 cases touched hard and the nodule was touched in two cases. Three patients had undergone a previous prostate biopsy, but prostate cancer was not found. All the 17 operations were successfully performed without conversion to open surgery. The surgery time was (85±21) (range from 45 to 120) min, the estimated blood loss was (25±18) (range from5 to 100) ml, the time of intake of liquid diet was (14.3±4.4) h, the intestinal recovery time was (23±10) h, the postoperative activity time was (22±7) h, the drainage duration was (3.7±0.8) d, the postoperative hospital stay was (4.9±1.2) days, and the catheter removal time was (7.4±1.5) days. In the early postoperative period (within 30 days after surgery), no obvious complications occurred. The postoperative final pathology confirmed that all the 17 specimens were prostate cancer. After a median follow-up of 6.5 months, the patient's urinary control rate reached 81.3% at postoperative 1 month, 92.3% at postoperative 3 months after surgery, and the urinary control rate reached 100% at postoperative 6 months. Postoperative PSA value was (0.08±0.08) μg/L, significantly lower than preoperative PSA level (P<0.001). There was significant difference between the preoperative and postoperative QOL (Quality of life) score (57±5 and 47±5 respectively, P<0.001) which indicated that the patients' postoperative quality of life was greatly improved. Conclusions: It is safe and feasible to perform minimally invasive radical prostatectomy without preoperative prostate biopsy for patients with highly suspected prostate cancer by comprehensive diagnostic mode based on modern new imaging technology.

Direct quantitation of free, encapsulated, total doxorubicin and doxorubicinol in stabilized frozen human plasma to support a BE study of liposomal doxorubicin. J Pharm Biomed Anal 2020; 189:113388. [PMID: 32663760 DOI: 10.1016/j.jpba.2020.113388] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2020] [Revised: 05/10/2020] [Accepted: 05/18/2020] [Indexed: 11/25/2022]
Abstract
Regulatory guidance requires the quantification of encapsulated and free doxorubicin for a liposomal doxorubicin injection bioequivalence study. Due to the instability of liposome formulations in plasma samples, the release of free drug from the liposomal encapsulated doxorubicin during sample handling would result in elevation of measured free doxorubicin concentration. To prevent the potential release of free drug, stabilizer reagents and procedures were successfully developed and validated to adequately stabilize liposomal drugs in plasma samples during sample collection, storage and extraction. Three LC-MS/MS methods were developed and fully validated for direct quantitation of free, encapsulated and total doxorubicin concentrations in human plasma according to relevant regulatory guidance: Method 1: Quantitation of free doxorubicin and doxorubicinol at a linear range of 1-400 ng/mL and 0.5-10 ng/mL, respectively, from stabilizer treated plasma samples using solid phase extraction (SPE); Method 2: Quantitation of encapsulated doxorubicin at a linear range of 50-50,000 ng/mL from the stabilizer treated plasma sample using SPE followed by PPE extraction method; Method 3: Quantitation of total concentration of doxorubicin from untreated plasma samples at a linear range of 50-50,000 ng/mL using PPE. All three methods were successfully used to support a bioequivalence study between Caelyx® and Duomeisu® (Doxorubicin Hydrochloride Liposomal injection, generic doxorubicin formulation produced by CSPC). Incurred sample reanalysis (ISR) passing rate for total doxorubicin, free doxorubicin/doxorubicinol, and encapsulated doxorubicin methods were 100 %, 84.7 %/100 %, and 98.5 %, respectively. The measured total doxorubicin concentrations matched the sum of free and encapsulated doxorubicin concentrations.

Abstract
PURPOSE This retrospective study aimed to assess the association between obesity, gender, and specific clinicopathological features in patients with papillary thyroid cancer (PTC) and whether diagnostic ultrasonography (US) is adversely affected by obesity in these patients. MATERIALS AND METHODS This study retrospectively analyzed 13,995 adult patients with PTC from a single medical center in China. Data stratification was performed to assess the association of obesity with US features and aggressive clinicopathological features in different models according to the World Health Organization Body Mass Index (WHO-BMI) and Chinese BMI classification (CN-BMI). The odds ratio (OR) of malignant US features and aggressive clinicopathological features was calculated from binary logistic regression models. RESULTS The BMI, obesity ratio, malignant US features, and aggressive pathological characteristics of males were significantly higher than those of females. After adjusting for confounding factors, the association of obesity with malignant US features and aggressive pathological characteristics was found to be sex-dependent. Next, obesity (WHO-BMI) was found to have an "interfering effect" on the US assessment of PTC (OR = 0.754, 95% CI 0.609-0.932, P = 0.009) in women. Among both sexes, obesity (WHO-BMI) increased the risk of tumor size (ORmale = 1.539 and ORfemale = 1.521) and multifocality (ORmale = 1.659 and ORfemale = 1.449). However, obesity did not increase the risk of capsular invasion or tumor staging in males. The above results are consistent with the CN-BMI. In addition, age was found to have an "interfering effect" on the US evaluation of malignant nodules in both sexes. CONCLUSION The results of our study confirm that higher BMI is significantly associated with aggressive clinicopathological features of PTC. Gender differences were present with obesity ratios and aggressive clinicopathological features being significantly higher in men.

Abstract
BACKGROUND We report a rare case of first branchial cleft anomaly (FBCA) accompanied by bony atresia of the external auditory canal, middle ear malformation, and location malformation of the facial nerve according to the intraoperative findings.
CASE SUMMARY A 19-year-old male patient presented to our department with a mass behind the right earlobe and recurrent postauricular swelling and pain since childhood, he also had severe hearing loss in the right ear since birth. The patient underwent surgery including mass removal, mastoidectomy, and simultaneous meatoplasty and ossiculoplasty under microscopy. No facial palsy or recurrence was noted during postoperative follow-up.
CONCLUSION FBCAs are rare, and to our knowledge, this is the first report of FBCA accompanied by external auditory canal bony atresia, middle ear malformation, and location malformation of the facial nerve. An effective postauricular approach under microscopy facilitated complete lesion removal and simultaneous otologic reconstruction.

Abstract
Objective: To Summarize the experience of pump-controlled retrograde trial off (PCRTO) in the process of veno-arterial extracorporeal membrane oxygenation (VA-ECMO) withdrawal in adult patients. Methods: Adult patients who received ECMO assistance in Intensive Care Unit for Cardiac Surgery from March to July 2019 were collected. According to our strategies, PCRTO was used if the patients can wean from VA-ECMO and hemodynamic indexes were recorded during the process. The statistics data was collected, including the 48 hours survival rate, ECMO re-assistance rate, thrombus complications, Intensive Care Unit (ICU) stay time and hospital stay time after weaning from VA-ECMO. The patients who failed in the test were continued to be assisted by ECMO. Results: There were 46 patients assisted by VA-ECMO in our center. In total, 21 adults who met the offline test standard underwent 26 PCRTOs, including 10 male adults (47.6%), with an age of 65 (55, 68) years old. Eighteen adults passed the withdrawal test. No new thrombus was found in the arteriovenous ultrasound of the lower extremity after weaning from ECMO, and no pulmonary embolism was found in the chest X-ray. The success rate of weaning from ECMO was 69.23%(18/26). The D-dimer decreased [584(348,2 107)μg/L vs 1 440(631,2 916)μg/L, P=0.014] and the left ventricular ejection fraction (LVEF) increased (51.4%±8.5% vs 46.9%±10.6%, P=0.013) on the next day after weaning. There were significant differences in heart rate (HR), central venous pressure (CVP), oxygenation index and lactate (Lac) during the PCRTO in the group which involved the cases of the 8 failed experiments (all P<0.05). Compared with the failure group, there were significant differences in age, blood flow rate, CVP before the test, HR, pulse oxygen saturation(SpO(2)), CVP, Lac and oxygenation index after the test, and the variations of SpO(2), CVP and Lac. Conclusion: PCRTO is a simple, reversible, safe and effective weaning method. It can be used in the process of VA-ECMO withdrawal in adult patients.

Abstract
Objective: To establish Chinese diet balance index for preschool children(DBI_C), and evaluate the dietary quality of Chinese preschool children. Methods: DBI_C was established according to the methods establishing DBI_16 and the recommended intake of different kinds of food for preschool children. Three scoring methods [low bound score (LBS), high bound score (HBS), diet quality distance (DQD)] were used to evaluate the dietary quality of preschool children selected from the 2010-2012 China National Nutrition and Health Surveillance. Scores [P50(P25, P75)] were compared to reflect the diet quality of preschool children in different regions. Results: DBI_C scores for cereals of preschool children from big city, middle and small city, normal rural area, and poor rural area were 0.0 (-2.0, 6.0), 0.0 (0.0, 6.0), 4.0 (0.0, 10.0), and 10.0 (2.0, 12.0), respectively (P<0.001), indicating that the intakes of cereals of preschool children were adequate. Scores for animal food of preschool children from four types of location were 0.0 (-2.0, 2.0), 0.0 (-6.0, 2.0), -4.0 (-6.0, 0.0), and -6.0 (-8.0,-2.0), respectively (P<0.001), indicating that the intakes of animal food of rural preschool children were inadequate. Scores for vegetable and fruit, milk and soybean were both less than 0 (P<0.001), indicating that the intakes of these food were insufficient in both urban and rural area. Scores of LBS, HBS and DQD were 24.0 (18.0, 30.0), 8.0 (3.0, 13.0) and 33.0(26.0, 39.0). Children without diet insufficient problem in four type of location accounted for 30.8%, 7.8%, 4.3% and 1.1%, respectively (P<0.001). Children without diet excessive problem accounted for 54.0%, 57.3%, 52.9% and 32.6%, respectively (P<0.001). Children without diet imbalance problem were 10.6%, 1.1%, 1.3% and 0.3%, respectively (P<0.001). Conclusion: Diet quality of urban preschool children is better than that of rural preschool children. Dietary imbalance is the main problem among Chinese preschool children.

Abstract
BACKGROUND Mycophenolate has been shown to be effective in glomerular disease. However, the role of mycophenolate in the first-line treatment of adult-onset idiopathic minimal change disease (MCD) has not been systematically studied in a randomized fashion. AIM To evaluate the therapeutic efficacy of enteric-coated mycophenolate sodium combined with low-dose corticosteroid as first-line treatment for MCNS. DESIGN A prospective, open-label, randomized clinical trial. METHODS Twenty adult patients with biopsy proven MCD were recruited and randomly assigned to receive either enteric-coated Mycophenolate Sodium (EC-MPS) plus low-dose prednisolone (Group 1: Prednisolone 0.25 mg/kg/day, n = 10) or standard-dose prednisolone (Group 2: Prednisolone 1 mg/kg/day, n = 10). RESULTS After 24 weeks of therapy, eight patients in Group 1 vs. seven of patients in Group 2 achieved complete remission (P = 0.606). Both groups showed a significant reduction of urine protein excretion (P < 0.05) and increased serum albumin (P < 0.001) vs. baseline levels. However, no significant between-group differences were demonstrated. The relapse rate was also similar in both groups. Both treatment regimens were well tolerated but there were more patient reported adverse effects in the standard-dose prednisolone group. CONCLUSION EC-MPS plus low-dose prednisolone is non-inferior to standard-dose prednisolone therapy in inducing clinical remission and preventing relapse in adult-onset idiopathic MCD and is associated with better tolerability and less adverse effects. This trial is registered with the ClinicalTrials.gov number NCT01185197.

Abstract
PURPOSE To explore whether probiotic supplementation could attenuate serum trimethylamine-N-oxide (TMAO) level and impact the intestinal microbiome composition. DESIGN Forty healthy males (20-25 years old) were randomized into the probiotic group (1.32 × 1011 CFU live bacteria including strains of Lactobacillus acidophilus, Lactobacillus rhamnosus GG, Bifidobacterium animalis, and Bifidobacterium longum daily) or the control group for 4 weeks. All participants underwent a phosphatidylcholine challenge test (PCCT) before and after the intervention. Serum TMAO and its precursors (TMA, choline and betaine) were measured by UPLC-MS/MS. The faecal microbiome was analyzed by 16S rRNA sequencing. RESULTS Serum TMAO and its precursors were markedly increased after the PCCT. No statistical differences were observed in the probiotic and the control group in area under the curve (AUC) (14.79 ± 0.97 μmol/L 8 h vs. 19.17 ± 2.55 μmol/L 8 h, P = 0.106) and the pre- to post-intervention AUC alterations (∆AUC) (- 6.33 ± 2.00 μmol/L 8 h vs. - 0.73 ± 3.04 μmol/L 8 h, P = 0.131) of TMAO; however, higher proportion of participants in probiotic group showed their TMAO decrease after the intervention (78.9% vs. 45.0%, P = 0.029). The abundance of Faecalibacterium prausnitzii (P = 0.043) and Prevotella (P = 0.001) in the probiotic group was significantly increased after the intervention but without obvious differences in α- and β-diversity. CONCLUSIONS The current probiotic supplementation resulted in detectable change of intestinal microbiome composition but failed to attenuate the serum TMAO elevation after PCCT. CLINICALTRIALS.

Abstract
OBJECTIVE To analyze the endemic situation of schistosomiasis in Hunan Province in 2019, so as to provide insights into the achievement of transmission interruption of schistosomiasis in the province in 2020. METHODS The data pertaining to Schistosoma japonicum infections in humans and livestock and snail status were captured from Hunan Province in 2019 and analyzed. RESULTS Schistosomiasis was endemic in 281 townships (towns) from 41 counties (districts) of 6 cities in Hunan Province by the end of 2019. A total of 991 900 persons received blood testing in Hunan Province in 2019, and 22 773 were positive for the blood testing, with sero-prevalence of 2.30%. All stool examinations were negative in 22 933 individuals detected. The high sero-prevalence was seen in Nanxian County, Anxiang County and Ziyang District. Currently, there were 5 034 cases with advanced schistosomiasis detected in Hunan Province, and they were predominantly identified in Yuanjiang City, Heshan District and Yueyang County. There were 44 963 bovines fenced in schistosomiasis-endemic villages in Hunan Province in 2019, which were predominantly distributed in Yuanjiang City, Hanshou County and Ziyang District, and no positives were detected in 1 996 bovines receiving blood testing or 20 684 bovines receiving stool examinations. In 2019, there were snail habitats of 1.73 billion m2 found in Hunan Province, which were mainly found in Yuanjiang City, Hanshou County and Yueyang County. CONCLUSIONS The endemic situation of schistosomiasis further decreases in Hunan Province in 2019; however, there is still a risk of schistosomiasis transmission in local areas of the province.

Abstract
Objective: To investigate the differences in efficacy between drug-eluting beads transbronchial arterial chemoembolization (DEB-BACE) combined with systemic chemotherapy and systemic chemotherapy alone for unresectable lung squamous cell carcinoma. Methods: Totally 60 cases of unresectable lung squamous cell carcinoma undergoing systemic chemotherapy in Yancheng Third People Hospital were retrospectively selected as the research object. According to patients' wishes, they were divided into chemotherapy-only group (group A) and combined treatment group (group B). Group A received gemcitabine combined with cisplatin chemotherapy. DEB-BACE was applied in the first half, and systemic chemotherapy was administered in the second half (starting 3 d after BACE). The first half and the second half of the chemotherapy dose were 1/2 of the drug dose in the chemotherapy alone group. The short-term efficacy, incidence of toxic side effects, peripheral blood T lymphocyte subsets, serum vascular endothelial growth factor (VEGF) levels, and survival time were compared between the two groups. Results: After 2 cycles of treatment, the total effective rates of group A and group B were 50.0% (15/30) and 76.7% (23/30) (P<0.05), the incidence of nausea and vomiting (63.3% vs 20.0%), decreased appetite (76.7% vs 43.3%), hair loss (86.7% vs 40.0%), and bone marrow suppression (40.0% vs 10.0%) in group A were higher than in group B (all P<0.05). After 2 cycles of treatment, the levels of CD3(+), CD4(+)and CD4(+)/CD8(+)in the two groups were higher than before treatment (group A: 47.7%±6.6% vs 52.3%±7.7%, 31.5%±4.9% vs 34.7%±5.8%, 1.05±0.24 vs 1.18±0.32; group B: 49.2%±7.0% vs 62.0%±14.0%,29.2%±5.5% vs 42.2%±7.3%, 1.07±0.26 vs 1.39±0.42; all P<0.05), while the level of CD8(+)was lower than before treatment (group A: 30.4%±5.4% vs 24.5%±4.8%; group B: 29.5%±4.1% vs 21.1%±4.5%; all P<0.05). The CD3(+), CD4(+), and CD4(+)/CD8(+) levels in group A were lower than those in group B (P<0.05), while CD8(+)level was higher than in group B (P<0.05). After 2 cycles of treatment, the VEGF levels in the two groups were lower than before treatment (group A: (423±85) vs (352±64) ng/L; group B: (404±114) vs (296±66) ng/L; P<0.05), and the VEGF level in group A was higher than that in group B (P<0.05). The 1-year survival rates of groups A and B were 54.9% and 77.9%, and the 2-year survival rates were 17.2% and 41.7% (Log rank χ(2)=4.750, P=0.029). Conclusion: DEB-BACE combined with systemic chemotherapy is superior to systemic chemotherapy in the treatment of unresectable lung squamous cell carcinoma. It can reduce toxic and side effects, improve immune function and prolong survival time, which is worthy of clinical application.

Abstract
OBJECTIVE To evaluate the effects of water body environments on the microbial community of Oncomelania hupensis snails in marshlands of the eastern Dongting Lake where natural extinction of O. hupensis snails are found, so as to explore the correlation between the natural extinction of O. hupensis snails and the microbial community in snails. METHODS Snails were caged water bodies in the Qianliang Lake marshland (Qianliang Lake regions) where natural extinction of snails was found and in the Junshan Park marshland (Junshan Park regions) in the eastern Dongting Lake for 30 days, and then all snails were collected and identified for survival or death. DNA sequencing of the fungi and bacteria was performed in snails before and after immersion in waters, and the biodiversity and abundance were analyzed. RESULTS The survival rates of O. hupensis snails were 28.0% (70/250) and 64.8% (162/250) in Qianliang Lake regions and Junshan Park regions 30 days after immersion in waters, respectively (χ2 = 81.365, P < 0.01). The number of the fungal community and the biodiversity of the bacterial community were both greater in snails caged in Qianliang Lake regions post-immersion than pre-immersion, and there was a significant difference in the structure of the fungal and bacterial communities. The microbial community with a significant difference included Flavobacteriaceae,which was harmful to O. hupensis snails. CONCLUSIONS The water body environment affects the composition of the microbial community in O. hupensis snails in marshlands with natural snail distinction around the eastern Dongting Lake; however, further studies are required to investigate whether the natural distinction of snails is caused by water body environments-induced changes of the microbial spectrum in O. hupensis snails.

Abstract
Polycrystalline Co2Ti1-xCrxO4 (0 ≤ x ≤ 0.2) inverse spinel ceramics have been synthesized via a sol-gel technique. The dc magnetization measurement in the field-cooled mode shows that negative magnetization could be observed until x reaches 0.2. The exchange constants are calculated using the ferrimagnetic Curie-Weiss fitting and the mean-field theory. This reveals that the strength of the inter sublattice magnetic interaction presents a non-monotonic trend with the increase in Cr content and reaches the minimum at x = 0.1, giving rise to the highest compensation temperature in the x = 0.1 sample. The applicability of the x = 0.1 sample is investigated in light of two prominent magnetic effects: (i) the stable magnetic switching effect indicates the potential applications in magnetic switching and data storage and (ii) the coexistence of normal and inverse magnetocaloric effects suggests a potential application in a constant temperature bath at 54 K.

Abstract
In this retrospective study, we compared the efficacy and safety of mechanical adjuvants in mucosal-sparing, mechanical endoscopic dacryocystorhinostomy (MMED) for primary acquired nasolacrimal duct obstruction (PANDO). 116 adult patients (90 female) aged 61 ± 11 received one of the following after MMED without topical mitomycin: no stenting or packing (group 1, n = 25), 1-week ostium packing by ribbon gauze (group 2, n = 29) or non-medicated absorbable gelatin sponge (group 3, n = 25), 8-week bicanalicular stenting (group 4, n = 28). 104 patients(92%) provided 12-month outcomes. Number of patients, age, gender, surgeon, and osteotomy size were comparable among groups (p = 0.4-0.9). Marginal significance was found in anatomical (group 1:80%, group 2:96.6%, group 3:96%, group 4:96.4%, p = 0.05) but not functional success (group 1:85%, group 2:85.7%, group 3:83.3%, group 4:88.9%, p = 0.75) at postoperative 12-month. Patients receiving any packing or stenting achieved better anatomical (96% versus 80%, p = 0.015) but not functional success (85% versus 86%, p = 0.90) compared to those receiving none. More patients receiving stenting developed postoperative granuloma than those who did not (87% versus 63%, p = 0.04). 1-week ostium packing was found to be as effective as 8-week bicanalicular intubation in improving anatomical outcome after MMED for PANDO. Functional outcome, however, did not differ among patients receiving mechanical adjuvant or not.

Abstract
Objective: To evaluate the clinical efficacy of endovascular treatment for non-thrombotic right iliac vein compression syndrome with intravascular ultrasound. Methods: The clinical data of 40 patients with non-thrombotic right iliac vein compression syndromereceiving intravascular ultrasound-assisted balloon dilatation combined with stent implantation from January 2012 to December 2018 were retrospectively analyzed. There were 32 males and 8 females, the average age of whom was 63 (46-81) years old. The patients were classified according to the CEAP (Clinical-Etiology- Anatomy-Pathophysiology) classification: 7 cases as C3, 18 as C4, 10 as C5 and 5 as C6. All patients underwent percutaneous right femoral vein puncture, intravascular ultrasound, and balloon dilatation combined with stentimplantation in the right iliac vein lesion location. Results: The success rate of clinical operations was 100%. There were no serious complications during the perioperative period. All patients were followed up for 4-58 months. During the follow-up period, the relief rate of limb edema was 88.6% (31/35), the pain relief rate was 86.7%(13/15), and the healing rate of ulcers was 100% (6/6). After the stent implantation, the endovascular area of the compression site was significantly enlarged (34.5mm(2)± 11.1mm(2)vs129.8 mm(2)±17.2 mm(2), P<0.001). The follow-up of color Doppler and/or anterograde angiography for deep veins of lower limb with digital subtraction angiography showed that the blood flow in the stentsweres mooth in all patients. Three cases were observed that the intimal hyperplasia led to mild in-stent restenosis, no obvious in stent restenosis (>50%). The abdominal X-ray plain film showed no obvious displacement and fracture of the stents. The venous clinical severity score (VCSS) was statistically significant (13.0±2.4 vs 6.2±2.0, P<0.001). The statistical results of short-form health surver SF-36 showed that the scores of life quality in all dimensions of the affected limb were significantly improved after operation (P=0.000). Conclusion: Intravascular ultrasound-assisted balloon dilatation combined with stent implantation is not only a safe and effective treatment for non-thrombotic right iliac vein compression syndrome, but also has a good mid-term patency rate.

Abstract
AbstractMicroencapsulated phase change materials (MicroPCMs) were fabricated using n-octadecane as PCM and melamine-formaldehyde as shell via in situ polymerization. They were coated with polypyrrole (PPy) to fabricate conductive microcapsules. The structure, morphology, thermal properties and the electrical conductivity of the microcapsules were characterized using the scanning electron microscope (SEM), the Fourier transformed infrared spectroscopy (FTIR), the thermo gravimetric analysis (TGA), the differential scanning calorimetry (DSC) and the standard four-probe method. The results show that, n-octadecane is well encapsulated in rough and compact spherical composites. The melting and freezing the composites latent heats are 90.2 and 92.0 J/g, respectively, while the mass percentage of the n-octadecane in the composites is 49.7%. The melting and crystallizing peak temperature of PPy/MicroPCMs is 24.6°C and 17.9°C, respectively. The addition of PPy improves the thermal stability of the composites. The conductivity of the PPy/MicroP-CMs increases from 0.1 S‧cm–1 to 0.33 S‧cm–1 as the PPy concentration increases from 3 to 10 wt%.
