[ABSTRACT]OBJECTIVETo study of the relationship of age and climate with the nasal mucosa lesions.METHODSAll the patients met with the inclusive criteria were registered and followed-up once a month and their nasal mucosal lesions were observed through nasal speculum and/or nasal endoscope. The recording data was analyzed by SPSS17.0 software.RESULTSA total of 259 patients, 555 person-times and 957 lesion spots were observed. The nasal mucosa was injured by airflow with the highest incidence rate from October to next year April. Patients numbers gradually increased after August, and significantly increased at November, December (P<0.05). Children aged from 2 to 12 years old and the adults aged from 40 to 80 years old were susceptible population (P<0.05), the incidence rate had a negative relation with humidity (P<0.05). The susceptible spots of the lesion were ranked as follows: Little area, inferior turbinate, mucosa of the both side of the deviated nasal septum, inferior meatus, middle meatus, middle turbinate and olfactory area. CONCLUSIONNasal mucosal injury relates to age and seasons. The nasal cavity airflow may be a factor of these lesions.

Objective To judge the effect of plasma exchange (PE) to the patients with severe hepatopath of nonage according to evaluating the change of the liver function of reserve with 13C-methacetin breath test. Methods There are two groups: the case group and the control group. Each group has 30 patients. The patients in the case group were treated by PE. All the patients received 13C-methacetin breath test at before or one week after treatment. MVmax40, CUM40 and CUM120 were present. At the same time, clinical symptoms, glutamate-pyruvate transaminase (ALT), total bilirubin (TBiL) and prethrombin active (PTA) were observed. Results MVmax40, CUM40, CUM120 and PTA were higher, ALT and TBiL were lower in the case group after treatment (t=4.679, 4.752, 5.048, 5.413, 6.208, 7.413, P=0.000,P<0.01). After a week, MVmax40, CUM40, CUM120 and PTA were higher, ALT and TBiL were lower in the case group than that in the control group (t=2.260, 2.247, 2.476, 4.017, 3.250, 3.658, P<0.05). The total effective rates in the case group and the control group were 83.3 % (25/30) and 43.3 % (13/30),which are significant different(χ2 10.335,P<0.01). Conclusion PE can im-prove the liver reservation functionin the severe hepatopath of nonage.

［18F］6-fluoro-3, 4-dihydroxy-L-phenylalanine(［18F］F-DOPA)has been used as a radiotracer for Parkinson′s disease over 30 years. The previously reported electrophilic synthesis method has low radiochemical yield(RCY), low specific activity(SA)and other defects. Recent reported nucleophilic synthesis of ［18F］F-DOPA could overcome the disadvantages. In this paper, the nucleophilic synthetic methods for ［18F］F-DOPA are reviewed.

Objective To isolate the glioblastoma multiforme stem cells (GBM-SCs) from GBM specimens and to investigate the biological role ofmiR-153 in GBM-SCs so as to explore the application of gene therapy of GBMs.Methods CD133+ cells were separated using magnetic cell sorting technique (MACS) after primary culture.Immunofluorescence staining was employed to detect the CD133,nestin,glial fibrillary acidic protein (GFAP),microtubule-associated protein 2 (MAP2) expressions; real time-PCR was used to analyze miR-153 mRNA expression in CD 133-cells and CD 133+ cells.Lipofectamine RNAiMAX was used to transfect MiR-153 mimic (miR-153 group) and scrambled control oligonucleotides (NC group) into GBM-SCs; 7 d after that,sphere formation assay was performed to determine the self-renewal ability of GBM-SCs.Real time-PCR and immunofluorescence were carried out to examine the CD133,nestin,GFAP,MAP2 mRNA and protein expressions.At last,the proliferation ability of miR-153 treated GBM-SCs and NC cells was determined by CCK-8 at 24,48,72,96 and 120 h after the transfection and the apoptosis ratio was detected by flow cytometry 3 d after the transfection.Results GBM-SCs isolated from GBM specimens could express stem cell markers CD133 and nestin; after differentiation,the cells could express astrocyte marker GFAP and neuron marker MAP2; miR-153 expression in CD133+ cells was signficantly down-regulated as compared with that in CD133-cells (P＜0.05).Seven d after transfection,the number of spheres in the NC group was significantly larger than that in the miR-153 group (P＜0.05); real time-PCR indicated that the mRNA expressions of CD 133 and nestin in the miR-153 group were significantly decreased,and the GFAP and MAP2 mRNA expressions were statistically increased as compared with those in the NC group (P＜0.05).The results detected by immunofluorescence were in accordance with those by real time-PCR; 48,72,96h after the transfection,cell viability in cells from miR-153 group was statistically significant lower than that in the NC group (P＜0.05); flow cytometry showed that the apoptosis rate of cells from the miR-153 group (9.4 1％±1.98％) was significantlyhigher than that in the NC group (4.28％±0.31％,P＜0.05).Conclusion Reactivation of miR-153 expression suggests novel therapeutic strategy for GBM-SCs.

Objective:To study the use of laparoscopic hepatic vein guided anatomic hepatectomy in the treatment of hepatocellular carcinoma.Methods:The clinical and follow-up data of 62 patients who underwent laparoscopic anatomic hepatectomy at the Department of Hepatobiliary Surgery of Southwest Hospital of the Army Medical University from January 2015 to February 2018 and met the inclusion criteria of the study were retrospectively analyzed. The operation procedure as to whether the main hepatic vein was exposed or not was determined. The patients were divided into the hepatic vein-oriented hepatectomy (HVOH) group when the main hepatic vein was exposed, and the traditional anatomic hepatectomy (TAH) group when the main hepatic vein was not shown. The perioperative and follow-up data of the two methods were compared.Results:A total of 31 cases were included in the HVOH group, there were 28 males and 3 females, age ranged from 29.0-70.0 (49.9±11.2) years. A total of 31 cases were included in the TAH group, there were 27 males and 4 females, age ranged from 22.0-73.0 (51.4±12.1) years. There were no significant differences in operation time, intraoperative blood loss, postoperative hospital stay, intraoperative conversion to open, and perioperative blood transfusion rates between the two groups ( P>0.05). The incidence of postoperative complication was significantly lower in the HVOH group than in the TAH group [9.7% (3/31) vs. 32.2% (10/31)] ( P<0.05), but no serious complications occurred (Clavein Level IV) in this study. The one-year tumor-free survival rate in the HVOH group was significantly higher than that in the TAH group (77.4% vs. 51.6%), ( P<0.05). There were no significant differences in the 1- and 3-year overall survival rates and tumor-free survival rates between the two groups ( P>0.05). Conclusion:Laparoscopic hepatic vein-guided anatomic hepatectomy for hepatocellular carcinoma had the potential advantages in reducing the perioperative complication rate, and enhanced the early tumor-free survival rates.

BACKGROUND: As one of the most common endocrinal disorders for women at childbearing age, the diagnostic criteria of polycystic ovary syndrome (PCOS) have been defined differently among different international health organizations. Phenotypic heterogeneity of PCOS also brings about difficulties for its diagnosis and management assessment. Therefore, more efficient biomarkers representing the progression of PCOS are expected to be integrated into the monitoring of management process using metabolomic approaches. METHODS: In this prospective randomized controlled trial, 117 PCOS patients were enrolled from December 2016 to September 2017. Classical diagnostic parameters, blood glucose, and metabolome were measured in these patients before and at 2 months and 3 months of different medical interventions. The receiver operating characteristic (ROC) curves were built based on multivariate statistical analysis using data at baseline and 3 months' management, and combinational biomarkers with appreciable sensitivity and specificity were selected, which then validated with data collected at 2 months. RESULTS: A set of metabolites including glutamic acid, aspartic acid, 1-methylnicotinamide, acetylcarnitine, glycerophosphocholine, and oleamide were filtered out with high performance in representing the improvement through 3-month management of PCOS with high sensitivity and specificity in ROC analysis and validation with other two groups showed an appreciable area under the curve over 0.96. CONCLUSIONS: The six metabolites were representative of the remission of PCOS through medical intervention, making them a set of potential biomarkers for assessing the outcome of PCOS management.

Objective:To investigate the differences in understanding and diagnosis of polycystic ovary syn-drome(PCOS)among obstetricians and gynecologists with different clinical experiences,in order to promote com-munication and improve medical quality.Methods:This was a multi-center cross-sectional survey.Information on participants'basic information and their knowledge of PCOS comorbidities and treatment management was col-lected online.Physicians were divided into two groups according to their experience:experienced(>200 consulta-tions/year)and inexperienced(≤200 consultations/year).The differences in the diagnosis and treatment of PCOS among different groups were compared.Logistic regression analysis was used to explore other factors that might influence the diagnosis and treatment of PCOS.Results:1689 questionnaires were finally included,among which 95 were experienced and 1594 were inexperienced.①In the comparison of basic conditions,the proportion of experienced persons in tertiary hospitals and reproductive endocrinology specialties was higher than that of in-experienced persons(P<0.05);The percentage of experienced persons who predicted patients with comorbid insulin resistance(proportion>30%)and predicted comorbid overweight/obesity(proportion 30%-50%)was higher than that of less experienced persons(P<0.05).②There was no significant difference in the evaluation of PCOS and its complications among different groups(P>0.05).Logistic regression suggested that different expe-riencers did not significantly affect the assessment of androgens,OGTT and lipid testing(P>0.05).③There was no statistical significance in the choice of treatment for those with no fertility need(P>0.05).For those with fertili-ty needs,metformin and letrozole were more actively selected by experienced group than inexperience(P<0.05).In terms of weight loss,experienced participants were more active in using metformin(P<0.05)and were more likely to choose1.0 or1.5 g/d(P<0.05)than those with inexperience.Conclusions:There was no signifi-cant difference in PCOS assessment among participants with different experience,but in treatment,experienced participants were better able to take into account the multi-system abnormalities brought by PCOS,and at the same time,they give more comprehensive and accurate treatment opinions on patients with or without fertility needs.

Objective:To investigate the clinical, endoscopic and pathological features, and treatment and prognosis of gastric adenocarcinoma of fundic gland type of chief cell predominant type (GA-FG-CCP).Methods:Data of 40 GA-FG-CCP patients with 41 lesions diagnosed by histopathology at Ningbo Medical Center Lihuili Hospital and Shanghai East Hospital from January 2018 to May 2023 were collected. Their clinical and endoscopic features, pathological features, immunohistochemical results, endoscopic treatment, and prognosis were analyzed.Results:Among the 40 GA-FG-CCP patients, there were 15 males and 25 females, and the mean age was 60.03 years. Most of them had no obvious clinical symptoms or family history of tumor. Except one case, others had no helicobacter pylori infection. The endoscopic features of white light observation were: ① the main location was the upper part of the gastric body (63.41%, 26/41); ② faded or whitish mucosal surface (56.10%, 23/41); ③ dilated vessels with branch architecture (78.05%, 32/41); ④ no background mucosal atrophy (100.00%, 41/41). The features of magnifying endoscopy with narrow band imaging (ME-NBI) were: ① no obvious demarcation line (85.37%, 35/41); ② enlargement of the crypt opening (87.80%, 36/41); ③ widening of the intervening part (92.68%, 38/41); ④ lack of irregular microvascular pattern (95.12%, 39/41). All patients were confirmed gastric adenocarcinoma of the fundic gland by biopsy. The glands showed a low degree of dysplasia, similar to the differentiation of chief cell predominant pattern, also with scattered parietal cells, forming irregular and anastomosing cords. In the 40 patients, 20 did not receive endoscopic therapy. Twelve out of 21 lesions in 20 cases treated with endoscopic resection infiltrated into the submucosa (20-520 μm), 9 cases were intramucosal carcinoma. There was no lymphatic or venous infiltration, and horizontal and vertical margins were negative. Immunohistochemical staining results showed that the tumor was postive for pepsinogen-Ⅰ and MUC 6, with scattered postive for H +-K +-ATPase, but negative for MUC5AC, MUC2 and CD10, and the Ki-67 labeling index was low. No patients had recurrence or metastasis during mean follow-up of 15.85 months. Conclusion:GA-FG-CCP is rare and very well differentiated. Its clinical symptoms are not obvious, but there is endoscopic characteristics. The detection rate of GA-FG-CCP can be improved by white light and ME-NBI, and the diagnosis can be confirmed by pathology and immunohistochemical staining.
