Abstract
Objective: To preliminarily examine the feasibility and outcome of single-port laparoscopic radical prostatectomy with full-length urethral preservation (FLUP-SPRP). Method: This study was a prospective case series study. A total of 25 patients with prostate cancer who met the enrollment criteria and agreed to this surgical procedure from March 2022 to December 2022 were collected at the Department of Urology, the Second Affiliated Hospital of Nanjing Medical University. The age of the patients was (67.2±7.6) years (range: 61 to 76 years). This novel procedure was performed by an experienced surgeon who performed single hole radical prostatectomy skillfully. Patient urinary control, tumor control, and related surgical complications after surgery were regularly monitored. Postoperative urinary control was evaluated using the daily amount of urine pad, 0 to 1 piece of urine pad was to restore urinary control, and 0 to 1 piece of pad within 24 hours after catheter removal was immediate urinary control. Result: All prodecures were successfully completed without transit to open surgery. The surgical time was (128.4±22.4) minutes (range: 100 to 145 minutes), the intraoperative blood loss was (68.2±13.7) ml (range: 50 to 120 ml). The urethral injury occurred in 4 cases during surgery and was repaired by sutures. The urinary control recovery rates within 24 hours, 1 week, 4 weeks, and 7 weeks after surgery were 80.0%, 84.0%, 92.0% and 100%, respectively. Postoperative large section pathology revealed 1 case with a positive basal margin of the prostate and negative margins of all prostate glands around the urethra. Postoperative complications included urinary tract infection in 3 cases, urodynia in 2 cases, and acute urinary retention in 1 case. MRI follow-up 3 months after surgery showed normal anatomy of the bladder and urethra. The follow-up values of prostate specific antigen at 3 and 6 months after surgery were less than 0.1 μg/L. Conclusions: The preliminary results of this study indicate that the FLUP-SPRP procedure is safe and feasible. The early results of postoperative urinary control and oncology are as expected.

Abstract
Zhongguo Yixue Dacidian(The Dictionary of Chinese Medicine,«») is the first comprehensive dictionary of traditional Chinese medicine in China. The dictionary, edited by Xie Guan()and compiled for several years by the teachers and students of Shanghai Special School of Traditional Chinese Medicine, was first published by The Commercial Press in 1921. In 1919, Lu Simian() joined The Commercial Press to assist Xie Guan who is his old friend in compiling the contents on medical books for the dictionary . In the same year, Lu Simian wrote a book called YiJi ZhiJin(«»). Recently, some scholars believe that Xie Guan disassembled YiJi ZhiJin and compiled it into Zhongguo Yixue Dacidian. Through a comparative study of these two, it can be seen that YiJi ZhiJin and Zhongguo Yixue Dacidian do use homologous materials in the interpretation of some medical books, but YiJi ZhiJin as a whole is not compiled into Zhongguo Yixue Dacidian, and the idea of there is a plagiarism relationship between them is incorrect.

Abstract
OBJECTIVE To investigate the prevalence of obstructive sleep apnea syndrome (OSAS) risk and related risk factors among children and adolescents of Hong Kong with cleft lip and/or palate (CL/P). DESIGN Retrospective survey study adopting three questionnaires, obstructive sleep apnea-18 (OSA-18), pediatric sleep questionnaire-22 (PSQ-22), and modified Epworth Sleepiness Scale (ESS). SETTINGS Multicenter study in two public hospitals. PATIENTS A total of 351 Chinese children and adolescents with non-syndromic CL/P (6-18-year-old, 57% males) visited between September 2017 and November 2019, with primary palatal repair surgery done before 3-year-old. MAIN OUTCOME MEASURE Positive OSAS risk was determined based on cut-off ≥60 for OSA-18, ≥8 for PSQ-22, and >8 for ESS. Age, sex, overweight presence, cleft type, embryonic secondary palate involvement, palatal repair surgery, palatal revision surgery, and orthodontic treatment were analyzed as possible risk factors. RESULTS A total of 9.5% of patients had positive OSAS risk based on OSA-18, 13.6% based on PSQ-22, and 13.2% according to ESS. A higher prevalence of patients with positive OSAS risk was of younger age (OSA-18, p = .034), had cleft involving embryonic secondary palate (PSQ-22, p = .009), and history of fixed orthodontic treatment (ESS, p = .002). The regression model identified only involvement of embryonic secondary palate as a risk factor (PSQ-22, odds ratio = 3.7, p = .015). CONCLUSIONS OSAS risk among children and adolescents of Hong Kong with CL/P was 9.5% to 13.6%. Patients at higher risk were those with cleft involving embryonic secondary palate. OSAS risk assessment may be influenced by different aspects of the disease spectrum, and a multimodal approach should be considered for such assessment.

Abstract
OBJECTIVE Triple-negative breast cancer (TNBC) is the most malignant form of breast cancer with increasing incidence and mortality worldwide. The progesterone receptor membrane component-1 (PGRMC1) is a well-identified hormone receptor with unknown functions in TNBC. The current study aims to explore the involvement of PGRMC1 in regulation of glutathione metabolism and ferroptosis during development of TNBC, providing new therapy options for TNBC patients. METHODS Bioinformatic analysis, cell proliferation assay, western blot assay and other biochemistry methods were performed in TNBC cells. RESULTS Our results revealed that the expression of PGRMC1 is higher in TNBC than the other subtypes of breast cancer. Interestingly, as an iron binding protein, increased PGRMC1 expression in TNBC cells leads to resistance to ferroptosis inducer. On the contrary, silenced PGRMC1 expression enhanced sensitivity of MDA-MB231 cells to Erastin. Mechanistically, overexpression of PGRMC1 decreased the intracellular free iron concentration, which was reduced by AG205 treatment. CONCLUSIONS PGRMC1 increases the possibility of TNBC development through binding to intracellular iron and suppressing ferroptosis, providing the molecular basis of combined treatment for TNBC.

Abstract
OBJECTIVE Triple-negative breast cancer (TNBC) is highly aggressive and leads to a poor prognosis. microRNA-181a (miR-181a) exhibits strong antineoplastic effects in many types of cancer. In this study, we examine the responses of human miR-181a-transfected TNBC cells and explore the mechanisms underlying the observed effects. METHODS A series of cellular assays were conducted using cells from the MDA-MB-231 TNBC line to assess the impact of miR-181a overexpression. The extracellular acidification rate, lactate production and glucose uptake were evaluated as a measure of aerobic glycolysis (i.e. the Warburg effect). The expressions of glycolysis-related gene were analyzed. RESULTS Viability, migration and survival of miR-181a-transfected MDA-MB-231 cells were all significantly reduced. miR-181a inhibited glycolysis in TNBC cells by reducing the rates of glucose uptake and lactate production and a substantial downregulation of factors known to contribute to the Warburg effect, including the serine/threonine kinase, AKT3, hypoxia-inducible factor-1α (HIF-1α) and progesterone receptor membrane component 1 (PGRMC1). CONCLUSION Our results demonstrate that miR-181a may regulate glycolysis in MDA-MB-231 TNBC cells, potentially via interference with components of the AKT3-HIF-1α and PGRMC1 pathways. These results suggest that miR-181a might be developed as a therapeutic agent for use in antineoplastic regimens directed at TNBC and PGRMC1-overexpressing breast cancers.

Abstract
Liao Ping, a famous scholar for Confucian classics in modern times has made great contributions to the field of Confucian classics. In particular, he interpreted Chinese medicine with the thinking of Confucian Classics. He delved into Inner Canon of Huangdi (Huang Di Nei Jing) and focused on recovering the methods of ancient diagnosis in this publication. He believed that the diagnostic measurement in Inner Canon of Huangdi were taken "to diagnose through cubit skin" and he then created such a diagnose method as his own. He put forward the theory of "Pi Luo Tong Zhen" which means "to diagnose diseases through cubit skin and what was shown on the skin holistically" and the theoretical framework of "Wu Zhen Fa" which means "to diagnose diseases by examining the skin, flesh, tendons, bones and veins comprehensively". While some contradictions and mistakes existed in terms of constructing the theories about the 'diagnosis through skin', Liao Ping interpreted the significance of cubit skin examination in Inner Canon of Huangdi and provided methodological enlightenment for later scholars to trace back to the origin of medical classics, and further explore the diagnosis and treatment system in Inner Canon of Huangdi.

Abstract
OBJECTIVES The prognostic value of preimplantation nutritional status is not yet known for older diabetic patients that received right ventricular pacing (RVP). The study aimed to investigate the clinical value of the four malnutrition screening tools for the prediction of heart failure hospitalization (HFH) in older diabetic patients that received RVP. DESIGN Retrospective observational cohort study. SETTING AND PARTICIPANTS This study was conducted between January 2017 and January 2018 at the Fuwai Hospital, Beijing, China, and included older (age ≥ 65 years) diabetic patients that received RVP for the first time Measurements: The Prognostic Nutritional Index (PNI), Geriatric Nutritional Risk Index (GNRI), Naples Prognostic Score (NPS), and the Controlling Nutritional Status (CONUT) score were used to estimate the preimplantation nutritional status of the patients. Univariate and multivariate Cox proportional hazard regression analyses were performed to investigate the association between preimplantation malnutrition and HFH. RESULTS Overall, 231 older diabetic patients receiving RVP were included. The median follow-up period after RVP was 53 months. HFH was reported for 19.9% of the included patients. Our results showed preimplantation malnutrition for 18.2%, 15.2%, 86.6% and 66.2% of the included patients based on the PNI, GNRI, NPS, and CONUT score, respectively. The cumulative rate of HFH during follow-up period was significantly higher for patients in the preimplantation malnutrition group based on the PNI (log-rank = 13.0, P = 0.001), GNRI (log-rank = 8.5, P = 0.01), and NPS (log-rank = 15.7, P < 0.001) compared to the normal nutrition group, but was not statistically significant for those in the preimplantation malnutrition group based on the CONUT score (log-rank = 2.7, P = 0.3). As continuous variables, all the nutritional indices showed significant correlation with HFH (all P < 0.05). However, multivariate analysis showed that only GNRI was independently associated with HFH (HR = 0.97, 95% CI: 0.937-0.997, P = 0.032). As categorical variables, PNI, GNRI, and NPS showed significant correlation with HFH. After adjustment of confounding factors, moderate-to-severe degree of malnutrition was an independent predictor of HFH based on the PNI (HR = 4.66, 95% CI: 1.03-21.00, P = 0.045) and GNRI (HR = 3.02, 95% CI: 1.02-9.00, P = 0.047). CONCLUSION Preimplantation malnutrition was highly prevalent in older diabetic patients that received RVP. The malnutrition prediction tools, PNI and GNRI, showed significant prognostic value in accurately predicting HFH in older diabetic patients with RVP.

Abstract
This paper introduced and summarized the ways and skills of promoting the circulation of air in the human body (Dao Yin Xing Qi) in Dao Yin Tu and Yin Shu and compared them with the way of breathing in Qu Gu Shi Qi. It was found that early Dao Yin drew on breathing thinking (Qi theory) and was meaningful for human health and helpful in examining how Qi theory was shaped and developed. It was also found that Dao Yin treated diseases based on meridian theories because Dao Yin for disease treatment in Dao Yin Tu and Yin Shu was related with the eleven meridians and their main symptoms in Mai Shu. The methods of practicing Dao Yin were likely to take references from the transmission routes of human meridians. The relationship between Dao Yin, Qi and meridians indicated that Qi and meridians were taken as the focus for people to understand the human body. Qi and meridians theories, widely accepted in ancient times, were taken as theoretical guidelines by stone needle, moxibustion and Dao Yin to maintain health and disease treatment.

Abstract
Veno-venous extracorporeal membrane oxygenation (VV-ECMO) is mainly used for reversible acute respiratory failure that is difficult to correct with mechanical ventilation and other conventional measures or preparation of lung transplantation. Acute respiratory distress syndrome (ARDS) is a typical clinical syndrome of acute respiratory failure. The timing of starting VV-ECMO in severe ARDS still face many controversies and challenges. This paper we discuss the current feasible assessment methods of when to start VV-ECMO in ARDS, such as, optimization of mechanical ventilation parameters, monitoring of respiratory dynamics and hemodynamics, assessment of lung recruitability and electrical impedance tomography (EIT) real-time monitoring, etc.

Abstract
AIM To determine whether the injection of haemocoagulase into the biopsy tract can reduce pneumothorax and pulmonary haemorrhage after computed tomography (CT)-guided percutaneous transthoracic lung biopsy (PTLB). MATERIALS AND METHODS A retrospective study was performed involving patients with undiagnosed pulmonary lesions scheduled for PTLB between January 2020 and March 2021. Patients were assigned to the haemocoagulase group or the non-haemocoagulase group. After CT-guided biopsies were performed with a 17 G coaxial system, patients in the haemocoagulase group received a haemocoagulase injection (0.2-0.5 units) in the biopsy tract as the sheath was withdrawn. Postoperative image studies were performed to evaluate complications, including pneumothorax and pulmonary haemorrhage. Factors, including the patient's position, lesion location, and pathological results, were evaluated to determine their associations with the complications. RESULTS A total of 100 patients were included, with 44 men and a mean age of 53 years old. The overall incidences of pneumothorax and pulmonary haemorrhage were 15% and 13%, respectively. The incidences of pneumothorax and pulmonary haemorrhage were statistically significantly lower in the haemocoagulase group (8% and 6%, respectively) than in the non-haemocoagulase group (22% and 20%, respectively; p=0.04 and 0.03, respectively). There was no statistically significant difference in haemoptysis between the haemocoagulase (6%) and non-haemocoagulase (2%) groups (p=0.23). There were also no statistically significant associations of pneumothorax or pulmonary haemorrhage with the patients' positions, lesion location, or pathological results. CONCLUSION Biopsy tract haemocoagulase injection reduced the incidences of postoperative pneumothorax and pulmonary haemorrhage after PTLB.

Abstract
OBJECTIVE This article reports the first live birth after cryopreserved ovarian tissue transplantation to prevent premature ovarian insufficiency in China. METHODS A patient with myelodysplastic syndrome received ovarian tissue cryopreservation before hematopoietic stem cell transplantation, and six ovarian cortex strips were thawed and transplanted into her peritoneal pocket 2 years later. RESULTS Pregnancy occurred spontaneously 27 months after grafting, and a healthy girl was born at 38 weeks gestation. Until now, the child has developed normally without any major diseases. CONCLUSIONS We report the first live birth resulting from ovarian tissue cryopreservation and transplantation in China.

Abstract
Limited therapeutic options are available for treating deep caries. Those materials with potential of a dual effect to remineralize hard tissue and regenerate defective dentin tissues could be used as a new strategy for deep caries treatment. However, the application of the single component remains a challenge mainly because they lack calcium and phosphorus, are easily degraded, and are difficult to retain in the intricate body fluid environment. Considering the abundant source of calcium and phosphorus as well as the delivery performance of mesoporous bioactive glass (MBG), an amelogenin-derived peptide (QP5), which has a significant role in hard tissue remineralization, was loaded to fabricate a novel composite. After the synthesis of highly ordered MBG using a sol-gel method, the QP5 peptide was loaded increasingly by its extensive porous structure and enhanced electrostatic absorption. When used in an acidic environment, the MBG/QP5 composite presented pH-responsiveness, releasing therapeutic ions and functional peptides in a sequential cascade, and eventually adjusted the pH to a neutral state. The composite was internalized by dental pulp cells through a clathrin-mediated pathway and influenced by cell membrane lipid raft regulation. It could be also transported through the macro-pinocytotic pathway. Compared to the single treatment of peptide QP5 in 48 h, the composite facilitated a higher level of retention of the intracellular peptides. The composite further promoted migration and odontogenesis of dental pulp cells, including the improved activity of alkaline phosphatase, increased formation of mineralized nodules, and upregulated expression of mineralization-related genes compared to using MBG or QP5 alone. The composite further induced the dentin-like layer in a rat pulp capping model. The results suggested that this intelligent material with pH-responsiveness provides a promising alternative treatment method for biomimetic restoration of deep caries.

Abstract
OBJECTIVE This study aimed to find evidence that progesterone receptor membrane component 1 (PGRMC1) promotes estradiol (E2) + norethisterone (NET)-induced breast cancer proliferation through activation of the phosphatidylinositol-3-kinase (PI3K)-AKT pathway. METHODS PGRMC1-mediated breast cancer cellular proliferation and phosphorylation of PGRMC1 were studied using wild-type (hemagglutinin [HA]-tagged) MCF-7 cells, which were stably transfected with expression vector containing HA (MCF-7-HA cells), PGRMC1 (MCF-7-PGRMC1 cells) and Ser181 point mutated PGRMC1 (MCF-7-PGRMC1-S181A cells). Bioinformatics, cell proliferation, western blot, isobaric tags for relative and absolute quantitation (iTRAQ)-based RNA sequencing, real-time quantitative polymerase chain reaction (RT-qPCR) and cell cycle in vitro assays were performed to indicate the function of PGRMC1 and its possible mechanisms in breast cancer. RESULTS NET + E2 elicited a significant proliferation in MCF-7-Vec at 10-6 M and 10-10 M, respectively. MCF-7-PGRMC1 did increase the phosphorylation of AKT or ERK, which can be blocked by treatment with casein kinase 2 (CK2) inhibitor quinalizarin or in MCF-7-PGRMC1-S181A cells. Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis revealed that the PI3K-AKT pathway is upregulated in MCF-7-PGRMC1 cells. Importantly, upregulation of the PI3K-AKT pathway mainly through promotion of cell cycle regulation strongly promoted cell proliferation in MCF-7-PGRMC1 cells. CONCLUSIONS CK2 is involved in phosphorylation of PGRMC1 at S181. The mechanism for the action of PGRMC1 for mediating proliferative progestogen effects obviously starts with promotion cell cycle regulation, and then activation of the PI3K-AKT pathway.

Abstract
Tanksuqnameh (Yi Li Han) as the earliest Persian transcription of traditional Chinese medicine for the west, has great value in the history of Sino-Iranian medical cultural exchanges. The eleven drawings attached to Tanksuqnameh concerning meridians and pulse diagnosis were compared to relative paintings attached to some ancient Chinese medical books. It was found that eight of the drawings attached to Tanksuqnameh came from the paintings attached to The Zhuan Tu Ju Jie of the Yellow Emperor Eighty-One Nan Jing by Li Jiong. The sources of the three paintings have not been identified. However, based on the comparison between the three paintings attached to Tanksuqnameh and the paintings in the medical books in the Ming Dynasty in terms of outlines, names and the content, they might come from the same medical book as a reference.

Abstract
Objective: To explore the consistency of peripheral whole blood and venous serum procalcitonin (PCT) levels, and the value of peripheral whole blood PCT in evaluating pediatric bacterial infection. Methods: This multicenter cross-sectional parallel control study was conducted in 11 children's hospital. All the 1 898 patients older than 28 days admitted to these hospitals from March 2018 to February 2019 had their peripheral whole blood and venous serum PCT detected simultaneously with unified equipment, reagent and method. According to the venous serum PCT level, the patients were stratified to subgroups. Analysis of variance and chi-square test were used to compare the demographic characteristics among groups. And the correlation between the peripheral blood and venous serum PCT level was investigated by quantitative Pearson correlation analysis.The PCT resultes were also converted into ranked data to further test the consistency between the two sampling methods by Spearman's rank correlation test. Furthermore, the ranked data were converted into binary data to evaluate the consistency and investigate the best cut-off of peripheral blood PCT level in predicting bacterial infection. Results: A total of 1 898 valid samples were included (1 098 males, 800 females),age 27.4(12.2,56.7) months. There was a good correlation between PCT values of peripheral whole blood and venous serum (r=0.97, P<0.01). The linear regression equation was PCTvenous serum=0.135+0.929×PCTperipheral whole blood. However, when stratified to 5 levels, PCT results showed diverse and unsatisfied consistency between the two sampling methods (r=0.51-0.92, all P<0.01). But after PCT was converted to ordinal categorical variables, the stratified analysis showed that the coincidence rate of the measured values by the two sampling methods in each boundary area was 84.9%-97.1%. The dichotomous variables also showed a good consistency (coincidence rate 96.8%-99.3%, Youden index 0.82-0.89). According to the severity of disease, the serum PCT value was classified into 4 intervals(<0.5、0.5-<2.0、2.0-<10.0、≥10.0 μg/L), and the peripheral blood PCT value also showed a good predictive value (AUC value was 0.991 2-0.997 9). The optimal cut points of peripheral whole blood PCT value 0.5、1.0、2.0、10.0 μg/L corresponding to venous serum PCT values were 0.395, 0.595, 1.175 and 3.545 μg/L, respectively. Conclusions: There is a good correlation between peripheral whole blood PCT value and the venous serum PCT value, which means that the peripheral whole blood PCT could facilitate the identification of infection and clinical severity. Besides, the sampling of peripheral whole blood is simple and easy to repeat.

Abstract
OBJECTIVE The aim of this study was to investigate genitourinary syndrome of menopause (GSM) in a large cohort, analyzing the dependency on age and menopausal status and possible differences between non-hysterectomized and hysterectomized women. METHODS Data were assessed by validated questionnaires, collected over 2 years for all eligible women attending our 'Menopause Clinic' from 31 Chinese provinces. Simple and unconditional logistic regression analysis was used with adjustments by all analyzed factors. RESULTS A total of 4063 women (mean age 50.53 ± 6.57 years), 2107 perimenopausal and 1956 postmenopausal, were included. Almost all GSM symptoms were more frequent and severe in postmenopausal women. GSM was more frequent in hysterectomized women compared to non-hysterectomized women. Independent of menopausal status, low sexual interest (92.78%), urinary incontinence (91.65%) and vaginal dryness (91.60%) were the top three GSM symptoms. Most severe were low sexual interest (21.01%), vaginal pain (20.10%) and decreased sexual pleasure (17.13%). Prevalence and severity of GSM were not related to age, but were related to menopausal status and increased with time since menopause. CONCLUSIONS Within 2 years, more than 4000 women with GSM traveled from all over China to our specialized clinic, indicating the great importance of GSM. Hysterectomy can increase the risk of GSM, and GSM symptoms increase from perimenopause to postmenopause and with an increase of time since menopause, pointing to the dependency on the loss of ovarian function.

Abstract
We numerically investigate the nonequilibrium behaviors of classic particles with competing interactions confined in a two-dimensional logarithmic trap. We reveal a quench-induced surprising dynamics exhibiting rich dynamic patterns depending upon confinement strength and trap size, which is attributed to the time-dependent competition between interparticle repulsions and attractions under a circular confinement. Moreover, in the collectively diffusive motions of the particles, we find that the emergence of dynamic structure transformation coincides with a diffusive mode transition from superdiffusion to subdiffusion. These findings are likely useful in understanding the pattern selection and evolution in various chemical and biological systems in addition to modulated systems, and add a new route to tailoring the morphology of pattern-forming systems.

Abstract
Nanoscale optical writing using far-field super-resolution methods provides an unprecedented approach for high-capacity data storage. However, current nanoscale optical writing methods typically rely on photoinitiation and photoinhibition with high beam intensity, high energy consumption, and short device life span. We demonstrate a simple and broadly applicable method based on resonance energy transfer from lanthanide-doped upconversion nanoparticles to graphene oxide for nanoscale optical writing. The transfer of high-energy quanta from upconversion nanoparticles induces a localized chemical reduction in graphene oxide flakes for optical writing, with a lateral feature size of ~50 nm (1/20th of the wavelength) under an inhibition intensity of 11.25 MW cm-2 Upconversion resonance energy transfer may enable next-generation optical data storage with high capacity and low energy consumption, while offering a powerful tool for energy-efficient nanofabrication of flexible electronic devices.

Abstract
BACKGROUND The regulator of cullins-1 (ROC1) is an essential subunit in the cullin-RING ligase (CRL) protein complex and has been shown to be critical in bladder cancer cell survival and progression. This study aimed to explore the molecular mechanism of ROC1 action in the malignant progression of bladder cancer. METHODS This study utilized ex vivo, in vitro, and in vivo nude mouse experiments to assess the underlying mechanisms of ROC1 in bladder cancer cells. The expression of the components of the sonic hedgehog (SHH) pathway was determined by western blot analysis. ROC1 expression in human tumors was evaluated by immunohistochemistry. RESULTS ROC1 overexpression promoted the growth of bladder cancer cells, whereas knockdown of ROC1 expression had the opposite effect in bladder cancer cells. Mechanistically, ROC1 was able to target suppressor of fused homolog (SUFU) for ubiquitin-dependent degradation, allowing Gli2 release from the SUFU complex to activate the SHH pathway. Furthermore, knockdown of SUFU expression partially rescued the ROC1 knockdown-suppressed SHH activity as well as cancer cell growth inhibition. In ex vivo experiments, tissue microarray analysis of human bladder cancer specimens revealed a positive association of ROC1 expression with the SHH pathway activity. CONCLUSION This study demonstrated that dysregulation of the ROC1-SUFU-GLI2 axis plays an important role in bladder cancer progression and that targeting ROC1 expression is warranted in further investigations as a novel strategy for the future control of bladder cancer.

Abstract
Complex-valued neural networks have many advantages over their real-valued counterparts. Conventional digital electronic computing platforms are incapable of executing truly complex-valued representations and operations. In contrast, optical computing platforms that encode information in both phase and magnitude can execute complex arithmetic by optical interference, offering significantly enhanced computational speed and energy efficiency. However, to date, most demonstrations of optical neural networks still only utilize conventional real-valued frameworks that are designed for digital computers, forfeiting many of the advantages of optical computing such as efficient complex-valued operations. In this article, we highlight an optical neural chip (ONC) that implements truly complex-valued neural networks. We benchmark the performance of our complex-valued ONC in four settings: simple Boolean tasks, species classification of an Iris dataset, classifying nonlinear datasets (Circle and Spiral), and handwriting recognition. Strong learning capabilities (i.e., high accuracy, fast convergence and the capability to construct nonlinear decision boundaries) are achieved by our complex-valued ONC compared to its real-valued counterpart.

Abstract
Abstract
Background
His-bundle pacing (HBP) is recognized as the most physiological way of pacing but with less study focused on electrical characteristics in different site.
Purpose
We aimed to evaluate the differences of pacing and echocardiographic parameters between atrial and ventricular side His-bundle pacing.
Methods
Patients who successfully underwent HBP implantation from September 2018 to August 2019 were retrospectively analyzed. All patients were assigned to atrial-side HBP (aHBP) group or ventricular-side HBP (vHBP) group according to the location of the His-bundle pacing lead, which was confirmed by two methods including postoperative echocardiography and visualization of tricuspid valve annulus (TVA). The pacing and echocardiographic parameters were compared between two groups during the procedure and at 3-month follow-up.
Results
A total of 71 bradycardia patients who successfully underwent HBP implantation and confirmed lead position were included. Among them, twenty-seven were assigned to aHBP group and the other 44 were assigned to vHBP group with no significant differences in baseline clinical characteristics between two groups. During the procedure, the proportion of selective HBP was significantly higher (77.8% vs. 11.4%; P<0.01) and the intra-procedural HV intervals was significantly longer (50.85±6.53 ms vs. 42.95±6.02 ms, P<0.01) in aHBP group than in vHBP group. The capture threshold in vHBP group was significantly lower than in aHBP group at implantation (0.92±0.22 V/1.0ms vs. 1.05±0.26 V/1.0ms, P=0.03) and remain significantly difference after 3-month follow-up (0.98±0.23 V/1.0ms vs. 1.15±0.44 V/1.0ms, P=0.03). The R-wave amplitude was significantly higher in vHBP group than in aHBP group at implantation (5.82±2.52 mV vs. 3.74±1.81 mV, P<0.01), and these differences still persisted during follow-up (5.88±2.51 mV vs. 3.67±1.61 mV, P<0.01). During 3-month follow-up, an increase in the capture threshold >1 V/1.0ms was seen in 2 cases in aHBP group while all patients remained stable in vHBP group. One patient developed a pocket hematoma in aHBP group compared to none in vHBP group. None of deterioration of tricuspid regurgitation and other procedure-related complications were observed during 3-month follow-up.
Conclusions
Ventricular side His-bundle pacing can achieve favourable pacing parameters including a lower pacing threshold and a higher R-wave amplitude than atrial side His-bundle pacing, which may be an ideal pacing strategy for patients in need of ventricular pacing.

Abstract
Abstract
Background
Atrial fibrillation (AF), one of the most common comorbidities with heart failure (HF), is associated with worse prognosis in HF patients receiving cardiac resynchronization therapy (CRT). However, there is still no convenient tool to evaluate and identify patients with high risk of mortality and hospitalization due to heart failure in CRT candidates with AF.
Methods
We included 152 consecutive patients with AF for CRT in our hospital from January 2009 to July 2019. Multivariate Cox regression was applied to derive a nomogram, using multiple imputation for missing values and backward stepwise regression for variable selection.
Results
Five predictors were incorporated in the nomogram, including N-terminal pro brain natriuretic protein (NTproBNP) >1745pg/mL, history of syncope, previous pulmonary hypertension (PHP), moderate or severe tricuspid regurgitation (TR), thyroid stimulating hormone (TSH) >4mIU/L. Concordance index (0.70, 95% CI 0.62–0.77), corrected concordance index (0.67, 95% CI 0.59–0.74) and calibration curve showed optimal discrimination and calibration of the established nomogram. Significant difference of overall event-free survival was recognized by the nomogram-derived scores in patients with high risk (>50 points), intermediate risk (21–50 points) and low risk (0–20 points) before CRT.
Conclusion
Our nomogram may be an applicable tool for early risk stratification among CRT candidates with AF.

Abstract
Shennong is the founder of cultivation, inventor of medicine. There are various recordation and legends about Shennong regional culture around the whole Chinese nation. The author studied the source of Shennong and Jingchu culture by comprehensively sorting relative literature recordation, citing unearthed materials in recent years as evidence, and found that the legends of Shennong is wide-spread in both western and southern China which corresponding to the origin of farming. What is more, a lot of delicate cultural relics and bambooslip and silk manuscripts have been found in Hubei and Hunan in recent years, which proved that Chu was not a land of barbarians in traditional view but an area with developed culture, and Shennong had a deep historic relation with Jingchu culture.

Abstract
OBJECTIVE The aim of this study was to investigate the role of microRNA-625-3p in the occurrence and progression of oral squamous cell carcinoma (OSCC) and its underlying mechanism. PATIENTS AND METHODS Expression levels of microRNA-625-3p, SCAI and E-cadherin in OSCC tissues and paracancerous tissues were detected by quantitative real time-polymerase chain reaction (qRT-PCR). MicroRNA-625-3p expression in OSCC tissues with different tumor stages and lymph node metastasis stages was analyzed. Survival analyses were conducted to access the diagnostic values of microRNA-625-3p and SCAI in OSCC. The effect of microRNA-625-3p on regulating cell migration of OSCC was detected by transwell assay. Luciferase reporter gene assay was conducted to verify the binding condition between microRNA-625-3p and SCAI. Rescue experiments were performed by co-transfection of microRNA-625-3p inhibitor and si-SCAI, followed by cell proliferation detection. RESULTS MicroRNA-625-3p was highly expressed in OSCC tissues than that of paracancerous tissues. OSCC patients with T3+T4 presented higher expression of microRNA-625-3p than those with T1+T2. Similarly, OSCC patients with N1+N2 presented higher expression of microRNA-625-3p than those with N0. Luciferase reporter gene assay identified that SCAI is the target gene of microRNA-625-3p. Furthermore, we found that SCAI and E-cadherin are lowly expressed in OSCC tissues than that of paracancerous tissues. ROC curve showed that microRNA-625-3p and SCAI exert certain values in diagnosing OSCC. MicroRNA-625-3p promoted migration of OSCC cells, which was reversed by SCAI knockdown. CONCLUSIONS MicroRNA-625-3p is highly expressed in OSCC, which promotes cell migration of OSCC by regulating SCAI expression.

Abstract
Lipoprotein lipase (LPL) is a key enzyme for lipid metabolism, playing a fundamental role in the composition of fat in adipose tissue and milk. The LPL gene has been seldom investigated in dairy ruminants and barely studied in river buffalo (Bubalus bubalis). The aim of this work was to explore the genetic diversity of LPL and its promoter and to identify functional mutations, using a combined approach based on sequencing, dual-color electrophoretic mobility shift assay, and quantitative PCR. Thirteen consensus sequences for transcription factors were found in the promoter. Eleven SNP were detected, and the attention was focused on the SNP with potential functional effects: g.-446A>G, because the presence of G created a consensus motif for the transcription factor Sp1, and g.107A>G, which was the only exonic SNP. We developed PCR-RFLP methods for genotyping the 2 SNP and calculated the allele frequencies. A strong linkage disequilibrium (D' = 1; r2 = 0.903) was found between the 2 SNP. The dual-color electrophoretic mobility shift assay demonstrated that only genotype g.-446GG allowed the binding of the Sp1 transcription factor, resulting in overexpression of the gene (~2.5 fold), as confirmed by the quantitative PCR results. Haploinsufficiency is proposed as a regulation mechanism. This study adds further knowledge on the structure of the LPL gene and its expression in river buffalo, with potential effects on milk qualitative and quantitative production.

Abstract
OBJECTIVES Monocyte-derived macrophages, as the predominant immune cell type that is increased in inflamed synovium, play a vital role during knee osteoarthritis (KOA) progression. However, the mechanisms underlying the recruitment of circulating monocytes to osteoarthritic knees remain uncertain. Based on previous data obtained from plasma, we investigated the contributions of CCL2, CCL3, CCL4 and their cognate receptors in circulating monocyte chemotaxis and KOA development. METHODS Using flow cytometry staining, we characterized the expression patterns of the chemokine receptors in CD14+CD16- circulating monocytes from KOA patients and healthy volunteers. The expression of chemokines in synovial fluids, synovium and cartilage was investigated in KOA patients and in patients without KOA. The role of chemokines and their cognate receptors in the chemotaxis of CD14+CD16- circulating monocytes was assessed using chemokine neutralizing antibodies (NA) and receptor antagonists in vitro and in vivo. RESULTS The majority of CD14+CD16- circulating monocytes were CCR1-and CCR2-positive. CCL2, CCL3 and CCL4 were elevated in synovial fluid of KOA patients compared with that of controls. The most likely source of these chemokines is inflamed synovium and cartilage in the osteoarthritic knee. The CCL3/CCR1 and CCL2/CCR2 axes showed substantial ability to recruit CD14+CD16- monocytes in transwell assays. Similar results were confirmed in a mouse model of collagenase-induced KOA (CIA) in which blocking either the CCL3/CCR1 axis or the CCL2/CCR2 axis reduced synovial hyperplasia and F4/80+ macrophage infiltration. CONCLUSIONS Our findings suggested that, analogous to the CCL2/CCR2 axis, CCL3 produced in osteoarthritic knees can chemoattract circulating monocytes to the inflamed synovium through CCR1.

Abstract
Neijing Tu(, Chart of Inner Landscape), collected by the Museum of Chinese Medical History, is a colored drawing which is used to guide Taoist internal alchemy training pattern. It belongs to the inheritance of the immortals in the Tao Yin(physical and breathing exercise) of traditional Chinese medicine in folk. It is the essence for nurturing vitality of the traditional Chinese medicine. Its core tenet is that one practices with both Shen(spirit) and Qi(pneuma) and makes both to fuse in perfect harmony way. The specific practice process includes four phases: refining Jing and converting it into Qi, refining Qi and converting it into Shen, extracting and then restoring Xu(void)from Shen, purifying Xu to fit Dao. This process contains the contents of the Secret Alchemy such as sub-Meridian Circle Vessel, overcoming the roadblock and entering Primary Meridian Circle Vessel, getting Yangshen (highest level spirit) and harmonizing the body and spirit. Its important value lies in being able to treat the disease which has not yet completely developed and the disease developed already.

Abstract
OBJECTIVE To observe the effects of different doses of propofol on the growth of transplanted liver tumor in BALB/C mice and check the expression of PCNA, CD34 and pAKT proteins to clarify the mechanism on molecule level. METHOD Human primary liver cancer cells SMMC-7721 were subcutaneously cultured in BALB/C mice, and the transplanted tumor model of BALB/C mice was constructed. Forty mice successfully modeled were randomly divided into 5 groups (n = 8): the blank control group (group C), low-fat milk group (group I), low-dose (50 mg/kg) propofol group (P1), middle-dose (100 mg/kg) propofol group (P2) and high dose (150 mg/kg) propofol group (P3). Tumor volume changes were observed at 3, 6, 9, 12, 15 and 18 days (T1, T2, T3, T4, T5, T6 and T7) before and after administration of the drug, and tumor growth curves were plotted. After 19 days of administration, all mice were killed for tumor collection, tumor weight was measured, and the tumor inhibition rate of propofol was calculated. The protein expression of cluster of differentiation 34 (CD34) in transplanted tumor was detected by immunohistochemistry, and the protein expression of proliferating cell nuclear antigen (PCNA) and phospho-Akt (pAKT) was detected by immunofluorescence. RESULTS Compared with group C, there was no significant difference in tumor volume in group I. At T2 ~ 7, the tumor volume of group P1, P2 and P3 decreased successively (P < 0.05). There was no significant difference in the inhibitory rate of tumor in group I, and the inhibitory rate of tumor in group P1, P2 and P3 increased successively (P < 0.05). There was no significant difference in PCNA, CD34, and pAKT protein expression in group I, while PCNA, CD34, and pAKT protein content in P1, P2, P3 groups were successively decreased (P < 0.05). CONCLUSION Propofol had a dose-dependent effect on the growth of liver cancer xenografts in mice, inhibiting the expression of PCNA, CD34 and pAKT proteins, and the effect was most obvious in the 150 mg/kg propofol group.

Abstract
The drug Fei Lian() in the unearthed medical book the Prescription for Nurturing Vitality () has been interpreted as Fei Lian(, an insect medicine) in Shennong Bencao Jing(, Shennong's Classic of Materia Medica). This article interprets it as herbal medicine Fei Lian(), not insect medicine Fei Lian() in Shennong Bencao Jing, based on the mutual evidence of unearthed documents and handed down documents, also the methods of phonology and exegesis. The word "Fei Lian" has rich cultural connotations, its etymology is related to "wind" , its semantics has the meaning of "light and fast speed" . It is used as the name of related totem image, legendary figures, historical figures, medicines, architecture and so on.

Abstract
BACKGROUND As a reliable biomarker of breast cancer, breast microcalcification has been reported to be correlated with poor prognosis. Bone morphogenetic protein 2 (BMP-2) plays an important role in microcalcification of breast cancer. Studies in other tissues have shown an association between BMP-2 and AKT/mTOR pathway, while their relationship in breast cancer still remains largely undetermined. To clarify the relationship of these three factors, we collected patients of invasive breast cancer with/without microcalcification and immunohistochemical examination was performed. METHOD/PATIENTS A total of 272 patients with primary invasive breast cancer were selected from the First Hospital of China Medical University from January 2010 to January 2012. Immunohistochemical examination of the BMP-2, p-AKT and p-mTOR was performed on 4-µm tissue microarray (TMA) sections. Then, we analyzed the relationship of BMP-2, p-AKT, and p-mTOR and their correlation with disease-free survival (DFS) in breast cancer with/without microcalcification. RESULTS We found that breast cancer patients with microcalcification were correlated with HER-2 positive expression and poor prognosis. Immunohistochemical examination showed that the expressions of BMP-2 and p-mTOR were increased in breast cancer with microcalcification and the expressions of BMP-2, p-AKT, and p-mTOR were correlated with each other. Moreover, the high expressions of BMP-2, p-AKT, and p-mTOR were significantly correlated with poor prognosis. CONCLUSIONS Based on the abovementioned findings, we hypothesized that the high expression of BMP-2 not only played a vital role in the formation of microcalcification, but also activated the AKT/mTOR pathway. Collectively, breast cancer patients with microcalcification were more likely to be resistant to targeted or endocrine therapy and be correlated with poor prognosis.

Abstract
OBJECTIVE To evaluate the impact of systemic lupus erythematosus (SLE) on health-related quality of life (HRQoL) assessed with SF-36 and explore factors associated with HRQoL in SLE patients. METHODS A random-effect meta-analysis was performed to calculate extracted data. Sensitivity and subgroup analyses were performed to distinguish sources of heterogeneity. RESULTS A total of 36 articles were finally included in this meta-analysis, including 6510 patients. The pooled mean scores of SF-36 physical component summary and mental component summary were 46.10 (95% confidence interval (CI): 43.09-49.10) and 50.37 (95% CI: 47.78-52.87), respectively. Spearman's correlation analysis found that mean age, proportion of female participants, and publication decades were negatively associated with some of the SF-36 domains. Sample size and SLEDAI were positively associated with some of the SF-36 domains. Patients with SLE have lower HRQoL in comparison to the general population. CONCLUSIONS SLE has a significant impact on HRQoL, which proves that the necessity of improving HRQoL in SLE patients cannot be ignored. Measuring HRQoL should be considered as an indispensable part of the overall evaluation of health conditions of SLE patients.

Abstract
High glucose (HG) induces vascular injury in diabetes. Hydroxysafflor yellow A (HSYA) has been used to ameliorate ischemic cardiovascular diseases in China for many years. In the present study, we assessed whether HSYA has a potential protective role in HG-induced human umbilical vein endothelial cell (HUVEC) injury. Cell viability was determined with an 3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium (MTS) assay. Cell apoptosis was detected by fluorescein isothiocyanate/propidium iodide staining assay. The endothelial cell permeability was measured with a permeability assay. Cell adhesion molecule (CAM) expression, vascular endothelial growth factor, and basic fibroblast growth factor levels were detected with an enzyme-linked immunosorbent assay. Reactive oxygen species (ROS) formation was measured with a DCF-DA assay. Protein expression of NADPH oxidase 4 (NOX4) was measured by Western blotting. Our data indicated that HG increases HUVEC apoptosis, vascular permeability, monocyte adhesion, the level of CAMs, the formation of ROS, and NOX4 expression. Our data revealed that HG increases vascular injury, which is attenuated by HSYA. Because vascular inflammation has a key role in the development of diabetes mellitus, our results implied that HSYA is considered as a potential agent for diabetic vascular injury treatment.

Abstract
Objective: Previous studies have shown that progesterone receptor membrane component 1 (PGRMC1) expressed in breast cancer tissue can predict a worse prognosis for breast cancer patients. Moreover, we demonstrated that PGRMC1 can increase the proliferation of progestogens. However, the role of PGRMC1 in terms of estrogen-induced proliferation and comparing different estrogens is still unclear. Methods: Non-transfected and PGRMC1-transfected T-47D cells were stimulated with estradiol (E2), with equilin (EQ), or with ethinylestradiol (EE) at 1, 10, and 100 nmol/l. Increase of proliferation was compared with a control (without estrogens) and with the estrogen-induced stimulation in empty vector cells vs. PGRMC1-transfected cells. Results: The empty vector cells showed significant proliferation (12-15%) with all three estrogens only at the highest concentration, with no relevant differences between the estrogens. PGRMC1-transfected cells showed about three-fold higher proliferation (29-66%), whereby E2 elicited the strongest and EE the lowest proliferating effects, significantly lower compared to E2 and also compared to EQ. No significant differences were seen between E2 and EQ. Conclusions: PGRMC1 increases strongly the estrogen-dependent breast cell proliferation. The proliferating effects of EE may be lower compared to E2 and EQ. This could have importance in comparing hormone therapy and contraception. Thus, PGRMC1 not only could predict the risk using progestogens but also of different estrogens.

Abstract
OBJECTIVES To investigate the distribution of alleles in 19 autosomal short tandem repeat (STR) loci in Jiangsu Han population. METHODS Goldeneye® 20A kit was used to detect 9 025 samples. Genetic analysis was performed on typing data of 19 autosomal STR loci, and genetic distance with other 17 populations was analyzed. RESULTS All the 19 autosomal STR loci were consistent with the Hardy-Weinberg equilibrium (P>0.05), with the heterozygosity 0.616 1-0.916 3, probability of match 0.012 8-0.202 6, discrimination power 0.797 4-0.987 2, probability of paternity exclusion 0.310 8-0.828 8, and polymorphic information content 0.561 7-0.913 6. The cumulative discrimination power and cumulative probability of exclusion were 0.999 999 999 999 999 998 434 1 and 0.999 999 989, respectively. The Jiangsu Han population had close genetic distances with the Han population in Tianjin, Hunan and Jilin, and significant difference with Han population in Aletai region in Xinjiang (P<0.05). CONCLUSIONS The STR allele polymorphism data and population genetic parameters of Jiangsu Han population can provide data support for the forensic application of these STR loci in Jiangsu Han population.

Abstract
The stearoyl-CoA desaturase (SCD) gene has been investigated in depth in ruminants because of its effect on milk fat composition. In river buffalo, the single nucleotide polymorphism (SNP) g.133A>C in the gene promoter has been associated with milk quality and yield. However, the biological reason for such effects remains unexplored. In this study, we combined mRNA profile analysis, an electromobility shift assay, and quantitative PCR to elucidate the role of this SNP on gene transcription and its effects on milk fat traits. A preliminary genotyping of g.133A>C was carried out on a group of 303 river buffaloes to choose individuals for the downstream applications. Analysis of allele frequencies showed an increase in the minor allele C (0.25) compared with previous findings (0.16). Six animals (2 for each genotype) were chosen for cloning and 216 positive cDNA recombinant clones for SCD (72 per genotype) were analyzed by PCR. All clones showed the same length on agarose gel; therefore, random clones were chosen for sequencing. No qualitative differences were found and all gene transcripts assembled correctly. An electrophoretic mobility shift assay was performed to evaluate the binding of the transcription factor Sp1 to DNA sequences including g.133A>C. Genotype CC showed a higher binding (mean ± standard error of the mean) than genotype AA in 2 different conditions [Enzo buffer (EB), Enzo Life Science Inc., Farmingdale, NY: 201.77 ± 4.06 vs. 141.65 ± 3.77 band intensity values and Poletto buffer (PB): 95.90 ± 1.15 vs. 67.30 ± 2.14 band intensity values]. The subsequent quantitative PCR confirmed the upregulation of the CC genotype compared with the AA and AC genotypes. The association study with milk fat traits revealed a favorable effect of allele C. The heterozygous genotype had the highest values for monounsaturated fatty acids, oleic acid (C18:1 cis-9), polyunsaturated fatty acids, and odd- and branched-chain fatty acids, and the lowest values for saturated fatty acids and atherogenic and thrombogenic indices; the heterozygous genotype differed significantly from the AA genotype. The AC genotype has previously been associated with higher milk yield. Therefore, the g.133A>C SNP is a marker with dual effects and is an interesting candidate for assisted selection programs in river buffalo. These data clarified the biological role of the SNP g.133A>C in the SCD promoter and how it affects gene function, providing important knowledge on the genetic background of lipid metabolism, including the future possibility of selecting alleles with quantitatively or qualitatively favorable effects.

Abstract
In various versions of Mai Shu(), "Chong head()" or "Chong headache()" is a disease of Foot-Taiyang Meridian. "Chong()" cannot be interchanged with "swell()" , and it does not have the meaning of "upward" . In ancient medical records, the headache due to "reversing Qi uprush" has nothing to do with Foot-Taiyang Meridian. The word "Chong()" is commonly used before the Han Dynasty as "collide" or "strike" . "Chong head()" or "Chong headache()" can be interpreted as a striking pain in head. which can reasonably solve the problems of disparate explanations in all versions of Mai Shu(), as well as the some internal problems of traditional medical principles.

Abstract
BACKGROUND Currently, there is no dedicated equation to estimate glomerular filtration rate (GFR) for transplanted kidneys. This study aimed to compare the performance of serum creatinine (Scr)- and cystatin C (CysC)-based equations in Chinese renal transplant recipients. METHODS A total of 252 stable renal transplant recipients were enrolled in this study. The plasma clearance of 99mTc-DTPA (rGFR) was used as a reference standard. The Scr, CysC, and rGFR of the patients were measured on the same day. The bias, precision, accuracy (percentage of estimates within 10%, 30%, and 50% of rGFR), and agreements of 8 Scr and 5 CysC eGFR equations were assessed. The factors affecting the accuracy were also evaluated. RESULTS Among the Scr-based equations, the Japanese Society of Nephrology-Chronic Kidney Disease Initiatives (JSN-CKDI) equation had the best overall performance with a bias of -6.2 mL/min/1.73 m2, and 96.1% of its estimates were within 30% of the rGFR. For the CysC-based equations, the Filler equation had the best performance with a bias of -3.9 mL/min/1.73 m2, and 93.7% of its estimates were within 30% of the rGFR. Overall, the CysC-based equations showed better performance than the Scr-based equations. In addition, significant differences were observed between bias and gender and between bias and rGFR value in some equations, whereas transplantation time and immunosuppressive regimens were not correlated with the bias. CONCLUSION The JSN-CKDI equation provides the best estimation of the GFR equations, and the CysC-based equations performed better than the Scr-based equations in this population.

Abstract
OBJECTIVE To test the reliability of the modified Huddart-Bodenham (MHB) numerical scoring system and its agreement with the GOSLON Yardstick categorization for assessing the dental arch relationships in unilateral cleft lip and palate (UCLP) cases. DESIGN A retrospective study. SETTING Faculty of Dentistry, The University of Hong Kong. PATIENTS Forty-one nonsyndromic UCLP consecutive patients attending the Joint Cleft Lip/Palate Clinic at Faculty of Dentistry in the University of Hong Kong were selected. INTERVENTIONS Study models at 8 to 10 years old (T1) and 10 to 12 years old (T2) were obtained from each patient. MAIN OUTCOME MEASURES Models were rated with the MHB scoring system and GOSLON Yardstick index. The intra- and interexaminer reliabilities as well as correlation of both scoring systems were evaluated. Furthermore, to investigate the outcome measurements consistency, the MHB scoring system and GOSLON Yardstick were independently used to compare the dental arch relationships from T1 to T2, with the samples split into intervention and nonintervention groups. RESULTS The MHB scoring system presented good intra- and interexaminer agreement, which were comparable to those of the GOSLON Yardstick. The correlation between the MHB scoring system and GOSLON Yardstick scores was good. Both scoring systems showed similar results when assessing the change in the dental arch relationships from T1 to T2. CONCLUSIONS The MHB scoring system can be used as an alternative method to the commonly used GOSLON Yardstick for assessing dental deformities in UCLP patients. Both scoring systems showed similar results in assessing the improvement in dental arch relationships.

Abstract
OBJECTIVES To investigate the genetic information of 30 insertion/deletion (InDel) loci in Han population from Jiangsu Province, and to explore the application values of Investigator® DIPplex kit for guiding the forensic analysis in Han population from Jiangsu Province. METHODS The autosomal InDel loci of 305 unrelated healthy Han individuals from Jiangsu Province were genotyped and analysed by Investigator® DIPplex kit, and the allelic frequencies and forensic parameters of 30 InDel loci were statistically analysed. RESULTS The distribution of 30 InDel loci in Han population from Jiangsu Province conformed to Hardy-Weinberg equilibrium. The minor allele frequencies of 21 InDel loci were above 0.3. The polymorphism information content ranged from 0.089 to 0.375, while the discrimination power distributed from 0.093 to 0.500. The paternity exclusion in duo cases and trio cases were 0.047-0.250 and 0.046-0.219, respectively. The linkage disequilibrium analysis of 30 InDel loci showed that all loci were independent from each other. The combined discrimination power was 1-7.369×10⁻⁸, whereas the combined mean exclusion chance in duo cases was 0.998 933 978, in trio cases was 0.997 806 392. The Fst values were all less than 0.06 except HLD118 and other four loci, which showed small differences between groups. CONCLUSIONS The InDel loci of Investigator® DIPplex kit can be used as complementary genetic markers for the cases associated with forensic genetics.

Abstract
Buffalo DGAT1 (diacylglycerol O-acyltransferase 1) was mainly investigated for the characterization of the gene itself and for the identification of the K232A polymorphism, similar to what has been accomplished in cattle, although no information has been reported so far at the mRNA level. The importance of DGAT1 for lipid metabolism led us to investigate the transcript profiles of lactating buffaloes characterized as high (9.13 ± 0.23) and low (7.94 ± 0.29) for milk fat percentage, and to explore the genetic diversity at the RNA and DNA level. A total of 336 positive clones for the DGAT1 cDNA were analyzed by PCR and chosen for sequencing according to the differences in length. The clone assembling revealed a very complex mRNA pattern with a total of 21 transcripts differently represented in the 2 groups of animals. Apart from the correct transcript (17 exons long), the skipping of exon 12 is the most significant in terms of distribution of clones with 11.6% difference between the 2 groups, whereas a totally different mRNA profile was found in approximately 12% of clones. The sequencing of genomic DNA allowed the identification of 10 polymorphic sites at the intron level, which clarify, at least partially, the genetic events behind the production of complex mRNA. Genetic diversity was found also at the exon level. The single nucleotide polymorphism c.1053C>T represents the first example of polymorphism in a coding region for the DGAT1 in the Italian Mediterranean breed. To establish whether this polymorphism is present in other buffalo breeds, a quick method based on PCR-RFLP was set up for allelic discrimination in the Italian Mediterranean and the Romanian Murrah (200 animals in total). The alleles were equally represented in the overall population, whereas the analysis of the 2 breeds showed different frequencies, likely indicating diverse genetic structure of the 2 breeds. The T allele might be considered as the ancestral condition of the DGAT1 gene, being present in the great part of the sequenced species. These data add knowledge at the transcript and genetic levels for the buffalo DGAT1 and open the opportunity for further investigation of other genes involved in milk fat metabolism for the river buffalo, including the future possibility of selecting alleles with quantitative or qualitative favorable effects (or both).
