Gastric cancer is one of the most common malignant tumors in China, and its pathogenesis is complex. At present, there is no good method for the diagnosis and treatment of gastric cancer. However, studies have shown that microRNA (miRNA) has abnormal expression in gastric cancer, which participates in the regulation of gastric cancer related genes, and has an impact on the occurrence, development, diagnosis and treatment of gastric cancer. This paper aims to review the relationship between miRNA and the diagnosis and treatment of gastric cancer, as well as the drug resistance in the treatment, so as to lay the foundation for the follow-up research and clinical diagnosis and treatment.

Objective:To investigate the efficacy of microsurgical treatment in cavernous sinus tumors.Methods:The clinical data of 87 patients with cavernous sinus tumor treated by microsurgery from January, 2010 to August, 2019 were analysed retrospectively. The surgical approaches and microsurgical skills for common tumors in Cavernous Sinus region were discussed. The follow-up included outpatient and telephone follow-ups, and the follow-up results were evaluated by KPS score.Results:Among the 87 cases, 57 were totally resected (65.5%), 14 were subtotal resected (16.1%) and 16 were major resected (18.4%). Hospitalisation ranged from 14 to 98 days, with an average of 29 days. Postoperative complications occurred in 30 cases with cranial nerve injury, 2 brain stem injury, 4 postoperative bleeding, 5 cerebrospinal fluid leakage, 4 infection, 1 Pituitary damage and 1 death. Prognosis and follow-up analysis showed 68 cases with KPS>60 and 66 with KPS>80 at 1 month after surgery; 74 with KPS>70 and 72 with KPS>80 at 3 months after surgery; 78 with KPS>80 by 12 months after surgery. During the follow-up period of 6-120 months, 3 cases died. Recurrence: 6 of incomplete resection of meningioma, were in 1-6 years after the surgery, 4 of incomplete resection of schwannoma in 1-8 years, 2 of pituitary adenoma respectively in 13 and 16 months after the surgery. There was no recurrence after reoperation. Two cases of chondrosarcoma, 3 of chordoma and 3 of germinoma were treated with radiotherapy, and during the follow-up, there was no progress of the focus. No tumor progression or recurrence was found in other cases during follow-up.Conclusion:Surgery of cavernous sinus tumor is difficult due to frequent postoperative complications. Reasonable preoperative plan, surgical approach and precise microsurgical techniques are the keys in reduction of postoperative complications and in the improvement of prognosis.

To compare transient elastorgaphy (FibroTouch) and acoustic radiation force impulse (ARFI) in diagnosis of liver fibrosis in patients with chronic hepatitis B.One hundred and forty five patients with chronic hepatitis B underwent FibroTouch and ARFI examinations in Xixi Hospital of Hangzhou from January to November 2015. The liver stiffness (LSM) was detected by FibroTouch and the liver shear wave velocity (VTQ) was detected by ARFI; liver biopsy was performed in all patients. With biopsy results as gold standards, the diagnostic values of FibroTouch and ARFI for liver fibrosis were analyzed with Spearman correlation analysis and receiver operating characteristic (ROC) curve.The correlation coefficient of FibroTouch and ARFI was 0.746 (<0.01). FibroTouch and ARFI were significantly correlated with pathological stage determined by liver biopsy(=0.705 and 0.727, all<0.01). When 8.4 kPa was taken as the cut-off value of LSM and 1.49 m/s was taken as the cut-off value of VTQ, the areas under ROC (AUCs) were 0.857 and 0.836 (>0.05) in diagnosis of fibrosis S≥2 stage; when 10.8 kPa of LSM and 1.49 m/s of VTQ were used as cut-off values, the AUCs were 0.872 and 0.881 (>0.05) in diagnosis of S≥3 stage; when 12.3 kPa of LSM and 1.81m/s of VTQ were used as cut-off values, the AUCs were 0.875 and 0.888 (>0.05) in diagnosis of S=4 stage.Both FibroTouch and ARFI can be effectively used in evaluation of liver fibrosis in patients with chronic hepatitis B.

OBJECTIVE:
To explore the clinical value of virtual touch tissue quantification (VTQ) technique and the PGA index [prothrombin time (P), γ-glutamyl transpeptadase (GG) and apolipoprotein A1 (ApoAl)] in evaluating the degree of liver fibrosis in alcoholic patients.
METHODS:
A total of 64 patients with long-term alcohol history were enrolled for this study. The liver ultrasonography elasticity was examined by VTQ techniques, the VTQ value was assessed in the liver target region, and then the PGA index was calculated. According the liver biopsy biological results, a golden standard, the patients were divided into a non-fibrosis group (n=11), a fibrosis group (n=10), a significant fibrosis group (n=14) and a cirrhosis group (n=29). The diagnostic value of VTQ and PGA index were compared in alcoholic patients following the classification of liver fibrosis.
RESULTS:
The elastography VTQ values were (1.38±0.33), (1.49±0.30), (1.76±0.22) and (2.28±0.53) m/s; while the PGA indexes were 2.09±0.94, 2.30±1.06, 3.57±1.09, and 2.21±1.99 in the non-fibrosis group, the fibrosis group, the significant fibrosis group and the cirrhosis group, respectively. The VTQ value and PGA index were positively correlated with the classification of liver fibrosis (VTG: r=0.719, PGA: r=0.683; both P<0.01).
CONCLUSION
The alcoholic liver fibrosis can be assessed by noninvasive VTQ technology and PGA index. As a real-time ultrasound elastography technique, VTQ is more accurate than the PGA index. Combination of the two methods is helpful for early diagnosis and treatment in the patients with alcoholic liver fibrosis.

8.Meta-analysis of aspirin-heparin therapy for un-explained recurrent miscarriage.
Chinese Medical Sciences Journal 2016;31(4):239-246
Objective This study was designed to evaluate the efficacy and safety of aspirin-heparin treatment for un-explained recurrent spontaneous abortion (URSA). Methods Literatures reporting the studies on the aspirin-heparin treatment of un-explained recurrent miscarriage with randomized controlled trials (RCTs) were collected from the major publication databases. The live birth rate was used as primary indicator, preterm delivery, preeclampsia, intrauterine growth restriction, and adverse reactions (thrombocytopenia ) were used as the secondary indicators. The quality of the included studies was evaluated using RCT bias risk assessment tool in the Cochrane Handbook (v5.1.0). Meta-analysis was conducted using RevMan (v5.3) software. Subgroup analyses were conducted with an appropriately combined model according to the type of the treatments if heterogeneity among the selected studies was detected. Results Six publications of RCTs were included in this study. There were a total of 907 pregnant women with diagnosis of URSA, 367 of them were pooled in the study group with aspirin-heparin therapy and 540 women in the control group with placebo, aspirin or progesterone therapy. Meta-analysis showed that the live birth rate in the study group was significantly different from that in the control group [RR = 1.18, 95% CI (1.00-1.39), P=0.04]. Considering the clinical heterogeneity among the six studies, subgroup analysis were performed. Live birth rates in the aspirin-heparin treated groups and placebo groups were compared and no significant difference was found. There were no significant differences found between the two groups in the incidence of preterm delivery [RR=1.22, 95% CI (0.54-2.76), P=0.64], preeclampsia [RR=0.52, 95% CI (0.25-1.07), P=0.08], intrauterine growth restriction [RR=1.19, 95% CI (0.56-2.52), P=0.45] and thrombocytopenia [RR=1.17, 95% CI (0.09-14.42), P=0.90]. Conclusion This meta-analysis did not provide evidence that aspirin-heparin therapy had beneficial effect on un-explained recurrent miscarriage in terms of live birth rate, but it was relatively safe for it did not increase incidence of adverse pregnancy and adverse events. More well-designed and stratified double-blind RCT, individual-based meta-analysis regarding aspirin-heparin therapy are needed in future.

Objective:
To analyze and assess the current status of high blood pressure and associated factors among primary and secondary school students in Xinjiang in 2023, so as to provide a scientific basis for prevention and control decision making of high blood pressure among students.
Methods:
From September to November 2023, a total of 94 205 primary and secondary school students aged 8-17 from 14 prefectures and cities in Xinjiang, were selected for physical measurement and questionnaire survey using a stratified clustering random sampling method. The χ 2 test was employed to compare differences in high blood pressure rates among students with varying characteristics. Additionally, a Logistic regression model was developed to analyze associated factors with high blood pressure among primary and secondary school students.
Results:
The overall high blood pressure rate among primary and secondary school students in Xinjiang was 8.18%, with simple systolic hypertension being the main type at 52.16%. By educational stages, high blood pressure rates for elementary school (grades 4-6), middle school, high school and vocational high school were 8.04%, 8.59%, 7.65%, and 9.72% respectively ( χ 2=29.16, P <0.01). The high blood pressure rates among obese and overweight students were 9.93% and 17.88% respectively, significantly higher than 5.32% among normal weight students ( χ 2=1 643.14, P < 0.01 ). The high blood pressure rate among urban students (8.73%) was higher than that of rural students (7.15%) ( χ 2=71.58, P <0.01). Logistic regression model analysis showed increased high blood pressure risk for girls than boys ( OR = 1.06 ); middle school, high school, and vocational high school students had increased high blood pressure risk compared to elementary school students ( OR =1.22, 1.16, 1.70); rural students had lower high blood pressure risk than urban students ( OR =0.90); the risk of high blood pressure in overweight and obese groups was higher than that in the normal group ( OR =1.54, 3.00), and the risk of high blood pressure in boarding students was lower than that in non boarding students ( OR =0.71)( P <0.01).
Conclusions
In Xinjiang in 2023, primary and secondary school students have a certain rate of high blood pressure, mainly characterized by elevated systblood pressure lower. The main prevention and control targets are females, urban residents, those in higher academic stages, non boarding students, as well as overweight and obese primary and secondary school students.
