ABSTRACT
Objective: To establish a nested recombinant enzyme-assisted polymerase chain reaction (RAP) technique combined with recombined mannose-binding lectin protein (M1 protein)-magnetic beads enrichment for the detection of Candida albicans (C. albicans) and Candida tropicalis (C. tropicalis) in blood samples for the early diagnosis of candidemia albicans and candidiemia tropicalis. Methods: The primer probes for highly conserved regions of the internal transcribed spacerregions of C. albicans and C. tropicalis were deigned to establish RAP assays for the detections of C. albicans and C. tropicalis; The sensitivity and reproducibility of nucleic acid tests with gradient dilutions of standard strains and specificity of nucleic acid tests with common clinical pathogens causing bloodstream infection were condcuted. M1 protein-magnetic bead enriched plasma C. albicans and C. tropicalis were used for RAP and PCR in with simulated samples and the results were compared. Results: The sensitivity of the established dual RAP assay was 2.4-2.8 copies/reaction, with higher reproducibility and specificity. M1 protein-magnetic bead enrichment of pathogen combined with the dual RAP assay could complete the detections of C. albicans and C. tropicalis in plasma within 4 hours. Fie the pathogen samples at concentration <10 CFU/ml, the number of the samples tested by RAP was higher than that tested by PCR after enrichment. Conclusion: In this study, a dual RAP assay for the detections of C. albicans and C. tropicalis in blood sample was developed, which has the advantages of accuracy, rapidity, and less contaminants and has great potential for rapid detection of Candidemia.

Objective: To understand the detection rate, epidemic pattern of respiratory syncytial virus (RSV) in hospitalized children with acute lower respiratory tract infection (ALRTI) in China. Methods: From June 2017 to March 2020, a prospective multi-center study on the viral aetiology among hospitalized children with ALRTI was conducted in six pediatrics hospital of North China, Northeast, Northwest, South China, Southeast, and Southwest China. A total of 2 839 hospitalized children with ALRTI were enrolled, and the respiratory specimens were collected from these cases. A multiplex real-time RT-PCR assay were employed to screen the respiratory viruses, and the molecular epidemiological and clinical characteristics of children infected with RSV were analyzed. Results: The positve rate of RSV was 18.6% (528/2 839), and the positive rate of RSV in different regions ranged from 5.5% to 44.3%. The positive rate of RSV in male was higher than that in female (20.2% vs 16.3%), and there was a significant statistically difference between two groups (χ2=6.74, P=0.009). The positive rate of RSV among children under 5 years old was higher than that among children older than 5 years old (22.3% vs 4.5%), and there was a significant statistically difference between two groups (χ2=97.98,P<0.001). The positive rate of RSV among the <6 months age group was higher than that of other age groups (all P<0.05). During January 2018 and December 2019, RSV was detected in almost all through the year, and showed peaks in winter and spring. RSV-positive cases accounted for 17.0% (46/270) among children with severe pneumonia, including 36 cases infected with RSV alone. Conclusion: RSV is an important viral pathogen in children under 5 years old with ALRTI in China. The virus can be detected almost all through the year and reached the peak in winter and spring. RSV could lead to severe pneumonia in children and caused huge threaten to children's health.

Lower lip hypoesthesia is the most common complication following osseous genioplasty. Concentrated growth factor (CGF) has recently been shown to improve neural regeneration. The aim of this study was to evaluate the effect of concentrated growth factor on neurosensory recovery after osseous genioplasty. Patients who underwent osseous genioplasty between June 2017 and February 2020 were enrolled. CGF was applied to the mental nerve on one side. The treatment side was randomized, and the other side was considered as the control. Lower lip hypoesthesia was assessed preoperatively and postoperatively (1 week, 1, 3, 6, and 9 months) using the two-point discrimination test and a 10-point visual analogue scale (self-reported paresthesia). The assessor was blinded. Twenty-six female patients completed the study. At 1 and 3 months, both the mean two-point discrimination value and mean visual analogue scale score were significantly lower in the CGF group than in the control group (P < 0.001). At 3 months, the percentage of patients with lower lip hypoesthesia in the CGF group was significantly lower than that in the control group (P < 0.001). Both groups showed resolution of lower lip hypoesthesia at 6 months. Concentrated growth factor may accelerate the recovery of long-standing sensory nerve impairment following mental osteotomy.

Objective: To explore the clinical utility of bronchoscopy and transbronchial cryotherapy in children with tracheobronchial tuberculosis (TBTB). Methods: Retrospective study was conducted to collect the clinical data of 10 hospitalized children who underwent bronchoscopy and were diagnosed as TBTB and in the Department of Pediatrics of Peking University First Hospital and the Department of Pediatric Respiratory Medicine of the Second Affiliated Hospital and Yuying Children's Hospital of Wenzhou Medical University from January 2011 to October 2019. The clinical characteristics of TBTB in children, and the efficacy and safety of bronchoscopy and transbronchial cryotherapy were summarized through descriptive analysis. Results: The onset age of 10 children (6 males and 4 females) ranged from 1-14 years. The clinical manifestations included fever (8/10), cough (7/10) and hemoptysis (2/10). Purified protein derivative test and interferon-γ release assay were performed in 9 and 10 patients respectively, the results were all positive. Chest CT examination was performed in all patients, and 8 patients had hilar and mediastinal lymphadenopathy. All patients underwent pediatric bronchoscopy in time, in 9 patients bronchus was found to be blocked in varying degrees by granulation tissue and caseous necrosis and in the remaining patient, obvious congestion and edema in bronchial mucosa. The bronchoscopic manifestations included 8 cases of lymph node fistula type, 1 case of granulation proliferative type and 1 case of inflammatory infiltration type. Pathological biopsies were performed in 7 cases, the findings were consistent with the pathological characteristics of tuberculosis. Nine patients were treated by pediatric bronchoscopic intervention, with 8 transbronchial cryotherapy by flexible bronchoscopy, and among them, 2 patients were treated by simultaneous rigid bronchoscopy. After 1-3 times of transbronchial cryotherapy, the blocked bronchial lumina in 8 cases were all recanalized, and the curative effect was significant without any serious complications. Conclusions: Bronchoscopy plays an important role in the diagnosis of TBTB in children and is helpful for its classification. Also, transbronchial cryotherapy has good efficacy and safety for TBTB in children, especially for the granuloproliferative type or lymph node fistula type.

Portal hypertension treatment has always been regarded as complex and diverse. With the innovation of concepts and technologies, its treatment model has been transformed from a single-disciplinary diagnosis and treatment model to a multidisciplinary collaborative diagnosis and treatment model. In the multidisciplinary diagnosis and treatment model, the surgical treatment of portal hypertension is not a treatment that is about to disappear soon, but one of the indispensable treatment methods under the multidisciplinary diagnosis and treatment model, and it will play an increasingly important role. Surgeons should formulate individualized, standardized, and minimally invasive treatment methods under the input of new concepts, master the surgical indications and individualized surgical methods for different populations, and maximize the optimization surgical treatment methods for portal hypertension. Therefore, it is necessary to re-examine the role of surgical treatment in the diagnosis and treatment of liver cirrhotic portal hypertension.

OBJECTIVE: To summarize and analyze the clinical characteristics of primary hyperpara-thyroidism (PHPT) with normocalcemic parathormone elevation (NPE) after surgical treatment, so as to improve the therapeutic ability and standardized post-operative follow-up of PHPT patients. METHODS: Nine patients who were diagnosed with PHPT in the Department of Endocrinology of China-Japan Friendship Hospital from August 2017 to November 2019 were selected as the subjects. They all developed NPE within 6 months after surgical treatment. The clinical features and outcomes were collected and analyzed retrospectively, in addition, the related literature was reviewed. RESULTS: Clinical features: among the 9 patients, 6 were middle-aged and elderly females and 3 were male. The main clinical manifestations were bone pain, kidney stones, nausea and fatigue except for one case of asymptomatic PHPT. Pre-operative examination showed high serum calcium [(3.33±0.48) mmol/L], low serum phosphorus [0.76 (0.74, 0.78) mmol/L], high 24-hour urinary calcium [8.1(7.8, 12.0) mmol/24 h], obviously elevated intact PTH [(546.1±257.7) ng/L], vitamin D deficiency [25-hydroxyvitamin D3 (21.0±5.7) nmol/L]. Serum levels of bone alkaline phosphatase [7 patients 41.3(38.6, 68.4) µg/L, 2 patients >90 µg/L] and N-terminal midcourse osteocalcin (>71.4 µg/L) were significantly elevated. The estimated glomerular filtration rate decreased in 2 patients. Imaging examination: 7 patients had osteoporosis. Renal calculi were found in 3 patients by renal ultrasound. Imaging examination of parathyroid glands found definite lesions in all the patients, including 2 cases of multiple lesions and 7 cases of single lesions. TREATMENT AND OUTCOME: two patients underwent parathyroidectomy, while other patients were treated with microwave thermal ablation. PTH increased 1 month after therapy [(255.0±101.4) ng/L], and no recurrent lesions were found by parathyroid ultrasound. After combined treatment with cal-cium and vitamin D for six months, PTH decreased significantly and the level of serum calcium remained normal at anytime during the follow-up period. CONCLUSION: The occurrence of postoperative NPE may be related to the higher pre-operative PTH, vitamin D deficiency and lower creatinine clearance. However, NPE may not predict recurrent hyperthyroidism or incomplete parathyroidectomy. Adequate calcium and vitamin D supplementation after surgery seems to be beneficial for patients with NPE. Post-operative follow-up of PHPT patients should be standardized to prevent and treat post-operative NPE.

Objective: To evalutate the safety and efficacy of infrahepatic inferior vena cava clamping robot-assisted laparoscopic liver resection. Methods: All data about 24 patients with robotic liver resection at Hepatic Surgery Center,Tongji Hospital,Tongji Medical College,Huazhong University of Science and Technology between February 2015 and December 2017 were collected and analyzed. These patients were divided into two groups based on different methods to decrease central venous pressure. Eight patients(6 males and 2 females,aged 49 years(range:50 to 56 years)) were applied with infrahepatic inferior vena cava clamping,and the other 16 matched cases (15 males and 1 female,aged 53 years(range:38 to 69 years)) were categorized into lowering central venous pressure group. Intraoperative blood loss,blood transfusion,intraoperative hemodynamic parameters,postoperative complications,and renal function were compared by t-test,non-parametric test,χ2 test,or Fisher exact test. Results: There was significantly difference in the intraoperative blood loss between the infrahepatic vena cava clamping group and the lowering central venous group(200(220) ml (range:100 to 400 ml) vs. 750(800) ml (range:100 to 2 000 ml),Z=â2.169,P=0.030). The clamping time of portal triad and infrahepatic inferior vena cava were 24 (18) minutes and 29 (20) minutes in the infrahepatic inferior vena cava clamping group, and portal triad clamping time was 23 (23) minutes in the low central venous group. There was no significant difference between the two groups (Z=â0.323, P=0.747). There was no intraoperative blood transfusion in the infrahepatic inferior vena cava clamping group, and 5 cases in the low central venous group, with a transfusion volume of 1.5(1.5)U. The difference between the two groups was statistically significant (Z=â3.353, P=0.001). However, the mean arterial pressure in the infrahepatic vena cava clamping group decreased from (88.6±4.9) mmHg to (67.4±3.8) mmHg(1 mmHg=0.133 kPa), which was lower than that of lowering central venous group (72.4±3.3) mmHg (t=2.315,P=0.003). And there were no significant differences related to postoperative complications rate or hepatic and renal function in both groups. Conclusion: The infrahepatic inferior vena cava technology is safe and feasible to decrease central venous pressure during robotic liver resections,which will not affect the recovery of hepatic and renal functions.

In the information age, teaching methods are undergoing tremendous changes, and the traditional teaching methods are difficult to draw students' attention. As the core course of stomatology, oral histopathology is an important foundation for oral students. Along with the rapid development of medical science, it is imperative to deepen the reform of teaching. This article discussed the diversified teaching methods conducted in oral histopathology course in Zhejiang University School of Stomatology in the past 10 years with the core teaching theory of "learning before teaching" including the exploration design course, case based learning, journal club, etc. Diversified teaching methods activated students' subjective initiative, which laid a foundation for the next stage of clinical study, and provided a guiding framework for the future teaching reforms.

COVID-19 is a Public Health Emergency of International Concern (PHEIC). Direct economic loss is expected to be much more than that of SARS outbreak in 2003. The risk factors of COVID-19 epidemic at the early stage included the misjudgment of the epidemic, delay in reporting this emerging infectious disease, nosocomial infection-caused transmission of the virus into local communities, and weak public health interventions. The infection rate (or the incidence) reflects the prophylactic effect in population. Case fatality reflects the therapeutic effect of clinical intervention. There were sufficient medical resources at the national top levels accumulated in Wuhan. Furthermore, medical professionals and sufficient medical supplies from other provinces have been assigned to join in the fighting against the epidemic in Wuhan. However, the case fatality in Wuhan has been kept the highest in China, indicating that clinical treatment for this virus-caused emerging infectious disease, whose pathogenesis remains to be elucidated, with limited effect in controlling this epidemic. The unusual, extremely costly public health interventions including the temporarily city quarantine and transportation ban issued by the central government are crucial in controlling this epidemic. The control of epidemic indicates the importance of public health measures but also reflected its insufficient capacity in China. Recently, profit-seeking mechanism run in Chinese health service system disorganized the balance of clinical service and public health service patterns in China, promoting the vicious circle of "attaching importance to clinical treatment and despising disease prophylaxis" , damaging the infrastructure of public health capacity, thus contributing to the formation of the inevitability in various fortuities of public health emergency. To strength the capacity of our medical service system to respond to public health emergency efficiently, two key issues should be considered. First, public health service, which should be fixed as the health section of the governments' public services by the law, must be greatly improved to meet the increasing health needs of the publics. Second, the vicious circle of profit-seeking-caused "attaching importance to clinical treatment and despising disease prophylaxis" should be immediately broken to optimize the national health service system in China by increasing the investment in public health service.

BACKGROUND: In China, ethnic minorities often live in frontier areas and have a relatively small population size, and tremendous social transitions have enlarged the gap between eastern and western China, with western China being home to 44 ethnic minority groups. These three disadvantages have health impacts. Examining ethnicity and health inequality in the context of western China is therefore essential. METHODS: This paper is based on data from the 2010 China Survey of Social Change (CSSC2010), which was conducted in 12 provinces, autonomous regions and province-level municipalities in western China and had a sample size of 10,819. We examined self-rated health and disparities in self-rated health between ethnic minorities and Han Chinese in the context of western China. Self-rated health was coded as poor or good, and ethnicity was coded as ethnic minority or Han Chinese. Ethnic differences in self-rated health was examined by using binary logistic regression. Associations among sociodemographic variables, SES variable, health behaviour variable, health problem variables and self-rated health were also explored. RESULTS: Fourteen percent of respondents reported their health to be poor. A total of 15.75% of ethnic minorities and 13.43% of Han Chinese respondents reported their health to be poor, indicating a difference in self-rated health between ethnic minorities and Han Chinese. Age, gender, marital status, education, alcohol, and health problems were the main factors that affected differences in self-rated health. CONCLUSION: In western China, there were obvious ethnic disparities in self-rated health. Elderly ethnic minorities, non-partnered ethnic minorities, ethnic minorities with an educational level lower than middle school, and ethnic minorities with chronic disease had higher odds of poor self-rated health.

The five-year overall survival rate with liver cancer currently ranks the second lowest among seventeen common malignant tumors in China. The occurrence and development of liver cancer is a process of progressive exacerbation. Nowadays, the clinical research is mainly aimed at the intermediate stage, that is, the exploration of the principle and method of diagnosis and treatment in the hospital. Notably, the research on the precancerous stage and the recovery stage after treatment of liver cancer are still seriously inadequate. We put forward a stepwise strategy to emphasize that only the full course of prevention and treatment study on liver cancer patients can significantly improve the overall efficacy of liver cancer in China.

ABSTRACT
Objective: To investigate the safety and feasibility of longitudinal transpancreatic U-sutures invaginated pancreatojejunostomy (Chen's pancreaticojejunostomy technique) in laparoscopic pancreaticoduodenectomy (LPD). Methods: Clinical data of 116 consecutive patients who underwent LPD using Chen's pancreaticojejunostomy technique in Hunan Provincial People's Hospital from May 2017 to December 2018 were retrospectively analyzed. Among these patients, 66 were males and 50 were females. The median age was 58 years old (32-84 yeas old). All 116 patients underwent pure laparoscopic whipple procedure with Child reconstruction method, using Chen's pancreaticojejunostomy technique. The intraoperative and postoperative data of patients were analyzed. Results: All 116 patients underwent LPD successfully. The mean operative time was (260.3±33.5) minutes (200-620 minutes). The mean time of pancreaticojejunostomy was (18.2±7.6) minutes (14-35 minutes). The mean time of hepaticojejunostomy was (14.6±6.3) minutes (10-25 minutes). The mean time of gastrojejunostomy was (12.0±5.5) minutes (8-20 minutes). The mean estimated blood loss was (106.0±87.6) ml (20-800 ml). Postoperative complications were: 11.2%(13/116) of cases had postoperative pancreatic fistula (POPF), including 10.3% (12/116) of biochemical fistula and 0.9%(1/116) of grade B POPF, no grade C POPF occurred; 10.3%(12/116) had gastrojejunal anastomotic bleeding; 3.4%(4/116) had hepaticojejunal anastomotic fistula; 3.4%(4/116) had delayed gastric emptying; 4.3% (5/116) had localized abdominal infection; 12.1%(14/116) had pulmonary infection; postoperative mortality were 0(0/116) and 1.7%(2/116) within 30 days and 90 days, respectively. One patient died of massive abdominal bleeding secondary to Gastroduodenal artery pseudoaneurysm rupture, the other patient died of extensive tumor recurrence and metastasis after surgery. Conclusions: Chen's pancreaticojejunostomy technique is safe and feasible for LPD.It is an option especially for surgeons who have not completed the learning curve of LPD.

Nasopharyngeal carcinoma (NPC) is the most common primary malignancy that originates from the nasopharynx. Some regulatory networks involved in nasopharyngeal carcinoma have been reported, but the relevant genes have not been fully identified. We have used mRNA microarray to identify differential expression genes between NPC tissues and adjacent normal tissues. Then high-content shRNA screening was carried out to screen the genes that may control proliferation in nasopharyngeal carcinoma. Cell proliferation was monitored by MTT assays and Celigo image cytometry in vitro and subcutaneous transplantation model in vivo. Flow cytometric analysis was carried out to detect the distribution of cell cycle stages and apoptosis. Transwell assay was performed to measure the migratory and invasive capacities of NPC cells. We identified 20 genes that potentially play an important role in the proliferation of nasopharyngeal carcinoma by mRNA microarray and functional analysis. The result of high-content shRNA screening indicated that STIL had the greatest effect on reducing the proliferation rate of NPC cells. The analysis of The Cancer Genome Atlas (TCGA) data showed that STIL was upregulated in several human cancer tissues, and higher STIL expression level was correlated with shorter survival time. STIL knockdown also inhibited NPC cell migration and invasion, promoted G1/S phase transition and apoptosis. Three genes including ITGA2, SMAD2, JAK1, associated with molecular mechanisms of cancer were influenced by downregulating STIL. Our study confirmed STIL as a key regulator that promotes the proliferation of NPC, providing insight into the molecular mechanisms of nasopharyngeal carcinoma and suggesting a novel therapeutic strategy.
