Objective To explore influence of JAK/STAT3 signaling pathway on the apoptosis of HCC cells.Methods DNA-vector-based RNAi approach silence was used to down-regulate STAT3 expression in Bel-7402 cells.According to the STAT3 cDNA sequence in the GeneBank database,the plasmid pGCsi.U6/neoRFP-STAT3 that was designed for expression of STAT3 siRNA was constructed and synthesized,and then transfected into the Bel-7402 cells with iipofectamine 2000.The apoptotic rate was measured with flow cytometry (FCM) and annexinV/PI apoptosis detection kit staining.The mitochondrial membrane potential (BΨm) was visualized by the JC-1 fluorescence staining and the inverted fluorescence microscope.Moreover,the expression of caspase-3 protein was analyzed by Western blotting.Results The apoptotic ratio of STAT3-siRNA group was (38.82 ± 0.88) ％,which was significantly higher than that in other group [control group (9.22 ± 0.38) ％,scramble-siRNA group (16.47 ± 1.04) ％,P ＜ 0.05].The mitochondrial membrane potential of STAT3-siRNA group observed by the JC-1 fluorescence staining was decreased significantly[(91.33 ± 1.78) ％] and [(89.90 ± 1.92) ％ vs (59.06 ± 1.89) ％,P ＜ 0.05].The Western blot results showed that the protein expression of active caspase-3 in STAT3-siRNA group was significantly higher than other groups (0.48 ± 0.05 vs 0.22 ± 0.04 and 0.26 ± 0.06,P ＜ 0.05).Conclusions STAT3 gene silencing significantly improves the apoptotic effect in the Bel-7402 ceils.

Objective To assess the wall elasticity of the common carotid artery using echo-tracking in healthy children and children with hyperlipidemia.Methods The study included 68 normal healthy children and 25 children with hyperlipidemia.All the subjects were 3-18 years old.They were divided into three groups according to ages 3-6 years old group,7-13 years old group and 14-18 years old group.Echo-tracking was used to measure the pressure-strain elastic modulus (E?),stiffness parameter(?)and arterial compliance (AC) of the common carotid artery.Results The average values of E? were different among the three age groups in normal healthy children (all P

OBJECTIVETo observe the clinical effects of acupuncture method of "Huoxue Sanfeng, Shugan Jianpi" (activating blood and eliminating wind, soothing liver and strengthening spleen) on morning blood pressure in patients with cerebral infraction combined with essential hypertension.

METHODSSixty-eight patients were randomly divided into an observation group and a control group, 34 cases in each one. The patients in the two groups were treated with acupuncture method of "Xingnao Kaiqiao" (consciousness-restoring resuscitation) and oral administration of nifedipine. In addition, patients in the observation group were treated with acupuncture method of "Huoxue Sanfeng, Shugan Jianpi" that met the criteria of standard manipulation, in which bilateral Renying (ST 9), Quchi (LI 11), Hegu (LI 4), Zusanli (ST 36) and Taichong (LR 3) were selected. The treatment was given once a day, five times a week, for totally six weeks. The improvement and control rate of morning blood pressure in the two groups were observed.

RESULTS(1) After treatment, the morning blood pressures were decreased significantly in the two groups (all P < 0.05); after 15 treatments, the reduction of systolic pressure and diastolic pressure in the observation group was superior to that in the control group, but the difference was not significant (both P > 0.05); after 30 treatments, the reduction of systolic pressure and diastolic pressure in the observation group was significantly superior to that in the control group (both P < 0.05). (2) After 30 treatments, the control rate of morning blood pressure in the observation group was significantly higher than that in the control group [82.4% (28/34) vs 58.8% (20/34), P < 0.05].

CONCLUSIONAcupuncture method of "Huoxue Sanfeng, Shugan Jianpi", characterized with standard manipulation criteria, can effectively control morning blood pressure in patients with cerebral infraction combined with essential hypertension.

OBJECTIVE: To investigate the allergens in patients with allergic rhinitis in Yichang, so that to find common allergens of Yichang and to provide statistic basis for a reasonable prevention and treatment to allergic rhinitis. METHOD: 1,979 patients with allergic rhinitis in Yichang were detected for allergens by skin prick test and the distribution of positive rates to inhaled allergens was compared between different genders and ages. RESULT: 1,545 (78.1%) of 1,979 suspected allergic rhinitis patients presented positive reaction. The positive rate in male was significantly higher than in female, and that in juvenile group was significantly higher than in adults. Among positive cases in inhalation group, the most common allergen was flour mite (80.4%), followed by house dust mite (64.9%), cockroach (13.3%) and artemisia pollen (8.2%). CONCLUSION The study shows that the flour mite and house dust mite are the most common inhaled allergens causing allergic rhinitis in Yichang. We should pay more attention to the prevention and treatment for the juvenile patients.

OBJECTIVE: To present a new approach for the research of effective components extracted from compounds of traditional Chinese medicine and their action mechanisms by high-throughput screening assay. METHODS: We observed the anti-oxidation activities of 240 sequential components (L1-L120 and A1-A120) extracted from Xiaoxuming Recipe, the effects of these components on SH-SY5Y cells with H(2)O(2)-induced and L-glutamic acid-induced damages and the levels of resting calcium ion in neurocytes of rats. RESULTS: Some components (L1-L40, A100-A120) extracted from Xiaoxuming Recipe had the corresponding effects listed above. The combination of these components was regarded as the groups of effective components of Xiaoxuming Recipe in treating sequelae resulting from brain ischemia. CONCLUSION: Xiaoxuming Recipe has protective effect on brain-ischemia-induced damages through the actions of multiple components with multiple targets.

Acute pancreatitis (AP) is the most common severe disease of digestive system, with high morbidity and mortality. In 2019, the latest version of guidelines for the management of acute pancreatitis (Shenyang, 2019) was launched. Starting from the etiology and classification of AP, the guidelines proposed 30 statements on the diagnosis and treatment of AP. The guideline fully reflected the level of evidence and consensus level of experts and provided suggestions for the clinical management of AP in the future. This review summarizes the key points of updating the guidelines, focusing on the classification principle of AP, the change of etiology, the unification of diagnostic name, the strategy of fluid resuscitation and antibiotic use to strenthen the understanding of the guidelines for better clinical practice.

China is a country with high incidence of gastrointestinal (GI) cancer. Gastric cancer, esophageal cancer and colon cancer seriously threaten the health of people, and leads to heavy medical burdens. This review discusses the current screening protocol of GI cancer and pancreatic cancer. It also interprets the relevant policies issued by the state in recent years, and evaluates the effects of new technologies such as serum pepsinogen combined with gastrin in detecting gastric cancer, fecal and blood gene detection for colon cancer, and "serum liquid biopsy" of pancreatic cancer for early cancer screening. We also point out the difficulties and challenges in cancer screening at early stage, and the significance of promoting early cancer screening to reduce the mortality of GI cancer in China.
