OBJECTIVE To investigate the effects of celastrol （CSL） on drug resistance of liver cancer cells. METHODS Human liver cancer lenvatinib （Len）-resistant cells Huh7/Len were constructed and divided into control group， CSL low-， medium- and high-concentration groups （1， 2.5， 5 μmol/L）， and CSL high-concentration+Zn27 [focal adhesion kinase （FAK） inhibitor] group （5 μmol/L CSL+2 nmol/L Zn27）， with 6 holes in each group. The proliferation （by absorbance） and cloning ability， apoptotic rate， the number of invasion cells and migration cells， the level of reactive oxygen species（ROS） as well as the protein expressions of phosphorylated FAK （p-FAK）， phosphorylated mitogen-activated protein kinase kinase （p-MEK）， phosphorylated extracellular signal-regulated kinase （p-ERK）， B-cell lymphoma-2 （Bcl-2）， Bcl-2 associated X protein （Bax） and caspase-3 were detected. RESULTS Compared with control group， cell absorbance， clone count， invasion count and migration count ， and the protein expressions of p-FAK， p-MEK， p-ERK and Bcl-2 were significantly reduced in the CSL low- ， medium- ， high- concentration groups； the apoptosis rate， ROS level， and protein expressions of Bax and caspase-3 were significantly increased， in a concentration-dependent manner （P＜0.05）. Compared with CSL high-concentration group， the changes of above indexes were all reversed significantly in CSL high-concentration+Zn27 group （P＜0.05）. CONCLUSIONS CSL can enhance oxidative stress， promote cell apoptosis， inhibit malignant progression and chemotherapy resistance of liver cancer cells， and its mechanism may be related to the inhibition of the FAK/MEK/ERK signaling pathway.

Objective:To investigate the clinical value of abdominal adipose volume in predicting early tumor recurrence after resection of hepatocellular carcinoma (HCC).Methods:The retrospective case-control study was conducted. The clinicopathological data of 132 HCC patients with tumor diameter ≤5 cm who were admitted to The First Affiliated Hospital of Army Medical University from December 2017 to October 2019 were collected. There were 110 males and 22 females, aged (51±4)years. All patients underwent resection of HCC. Preoperative computer tomography scanning was performed and the visceral and subcutaneous fats of patients were quantified using the Mimics Research 21.0 software. Based on time to postoperative tumor recurrence patients were divided to two categories: early recurrence and non-early recurrence. Observation indicators: (1) consistency analy-sis; (2) analysis of factors influencing early tumor recurrence after resection of HCC and construction of prediction model. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribu-tion were represented as M( Q1,Q3) or M(range), and comparison between groups was conducted using the Mann-Whitney U test. Count data were expressed as absolute numbers, and comparison between groups was conducted using the chi-square test or Fisher exact probability. Consistency analysis was conducted using the intragroup correlation coefficient (ICC) test. Multivariate analysis was performed using the binary Logistic regression model forward method. Independent risk factors influencing early tumor recurrence after resection of HCC were screened. The area under curve (AUC) of receiver operating characteristic (ROC) curve was applied to select the optimal cut-off value to classify high and low risks of recurrence. The Kaplan-Meier method was used to draw survival curve and calculate survival time. The Log-Rank test was used for survival analysis. Results:(1) Consistency analysis. The consistency ICC of abdominal fat parameters of visceral fat volume (VFV), subcutaneous fat volume, visceral fat area, and subcutaneous fat area measured by 2 radiologists were 0.84, 1.00, 0.86, and 0.94, respectively. (2) Analysis of factors influencing early tumor recurr-ence after resection of HCC and construction of prediction model. All 132 patients were followed up after surgery for 662(range, 292-1 111)days. During the follow-up, there were 52 patients with non-early recurrence and 80 patients with early recurrence. Results of multivariate analysis showed that VFV was an independent factor influencing early tumor recurrence after resection of HCC ( odds ratio=4.07, 95% confidence interval as 2.27-7.27, P<0.05). The AUC of ROC curve based on VFV was 0.78 (95% confidence interval as 0.70-0.85), and the sensitivity and specificity were 72.2 % and 77.4 %, respectively. The optimal cut-off value of VFV was 1.255 dm 3, and all 132 patients were divided into the high-risk early postoperative recurrence group of 69 cases with VFV >1.255 dm 3, and the low-risk early postoperative recurrence group of 63 cases with VFV ≤1.255 dm 3. The disease-free survival time of the high-risk early postoperative recurrence group and the low-risk early post-operative recurrence group were 414(193,702)days and 1 047(620,1 219)days, showing a significant difference between them ( χ2=31.17, P<0.05). Conclusions:VFV is an independent factor influen-cing early tumor recurrence of HCC after resection. As a quantitative indicator of abdominal fat, it can predict the prognosis of HCC patients.

Objective To investigate the risk factors and preventive strategies of pancreaticoduodenectomy postoperative hemorrhage.Methods A total of 208 patients who underwent pancreaticoduodenectomy in the Department of Hepatobiliary Surgery of the 904th Hospital of Joint Logistics Support Force,PLA from January 2017 to December 2021 were enrolled.Twenty-one patients with postoperative hemorrhage were retrospectively analyzed.Results Univariate analysis indicated that postoperative hemorrhage was mainly associated with pancreatic leakage,biliary leakage,abdominal infection,hypoproteinemia,diabetes,improper use of ultrasound knife,skeletonization,intraoperative blood loss,preoperative jaundice,etc.(P<0.05),but not gender and age(P>0.05).Among the 21 patients with postoperative hemorrhage,4 cases recovered after conservative treatment such as hemostasis and blood transfusion,6 cases underwent interventional treatment,11 cases underwent abdominal exploration,and 2 cases died of postoperative multiple organ failure.Pancreatic leakage(OR=3.963,95%CI:1.120-14.025),biliary leakage(OR=4.013,95%CI:1.173-13.734)and abdominal infection(OR=7.545,95%CI:1.833-31.051)were independent risk factors for postoperative hemorrhage.Conclusions The improvement of anastomotic manipulation,reduction of anastomotic leakage,and control and prevention of abdominal infection are important to prevent postoperative hemorrhage of pancreaticoduodenectomy.Surgical treatment should be performed as soon as possible for the patients with poor conservative treatment effect.

Objective:To explore the clinical efficacy of arthroscopic repair of ulnar tear of triangular fibrocartilage complex (TFCC) by loop stitch using a suture anchor.Methods:A retrospective case series study was used to analyze the clinical data of 46 patients with TFCC ulnar tear admitted to Ningbo Sixth Hospital from February 2019 to October 2020, including 28 males and 18 females; aged 18-64 years [(35.9±10.3)years]. All the patients had unilateral tears, including 18 on the left side and 28 on the right side, and all of them had Palmer type IB injuries. During the operation, one anchor was placed in the proximal end of the ulnar styloid process, and the ulnar side tear of the TFCC was repaired using arthroscopic anchor loop suture method. The visual analogue score (VAS), modified Mayo wrist score, disability of the arm, shoulder and hand (DASH) score, hand grip strength, wrist flexion and extension, and forearm rotation range of motion were compared before operation, at 3 months after operation, and at the last follow-up. The healing of surgical incisions and postoperative complications were observed.Results:All the patients were followed up for 13-35 months [24.0(17.5, 28.0)months]. The VAS, modified Mayo wrist score, DASH score and hand grip strength were improved from preoperative (4.2±0.9)points, (72.9±8.1)points, (27.9±4.7)points and (17.4±3.6)kg to (2.6±1.7)points, (82.1±6.1)points, (15.3±4.2)points and (20.3±3.5)kg at postoperative 3 months, and to (0.7±0.3)points, (91.8±4.2)points, (12.3±3.8)minutes and (23.6±4.1)kg at the last follow-up ( P<0.05 or 0.01), which were further improved at the last follow-up when compared to those at postoperative 3 months (all P<0.05). Based on the modified Mayo wrist score, the results were excellent in 28 patients, good in 14, and fair in 4 at the last follow-up, with an excellent and good rate of 91.3% (42/46). No significant differences were found in the wrist flexion-extension or forearm rotation range of motion before operation, at 3 months after operation, or at the last follow-up (all P>0.05). All surgical incisions achieved phase I healing. The postoperative complications included hypoesthesia and numbness of the skin on the ulnar side of the hand dorsum and the dorsal proximal section of the little finger in 3 patients and tenderness at the anchor in 2. No anchor loosening or prolapse occurred at the last follow-up. Conclusion:Arthroscopic repair of TFCC ulnar tear by loop stitch using a suture anchor can effectively relieve ulnar-sided wrist pain, improve the function of the wrist joint and upper limbs, and increase the grip strength of the hand, with fewer postoperative complications, making it an effective treatment method for TFCC ulnar tear.

Influenza is a worldwide infectious disease caused by influenza virus. It has posed great challenges on public health and social stability since 1918. At present, vaccination is the most effective way to prevent and control influenza epidemics. Broad-spectrum antiviral drugs and neutralizing antibodies against influenza virus have been widely studied in recent years. Hemagglutinin (HA), which is on the surface of influenza virus, plays an important role in the stage of viral invasion into host cells. It is the main effective antigenic component of current influenza vaccines, as well as the main target of broad-spectrum neutralizing antibodies and broad-spectrum antiviral drugs. This review summarized the progress in the development of novel influenza vaccines, neutralizing antibodies, and antiviral drugs based on influenza virus HA, as well as other prevention and control measures, hoping to present new ideas for future influenza prevention and control.

Objective:To investigate the effects of urinary nickel exposure on insulin resistance, islet function and diabetes risk in adults aged 18 years and above in China.Methods:Based on the China National Human Biomonitoring from 2017 to 2018, a total of 500 diabetes patients were randomly selected as the case group, and the matched euglycemic control were selected by 1∶1 matching ratio. The urinary and venous blood samples of the subjects were collected, and the urinary nickel levels and serum glucose metabolism indexes such as fasting blood glucose and fasting insulin were detected, and the insulin resistance index (HOMA-IR), β cell function index (HOMA-β), and adjusted HOMA-β were calculated by using homeostasis model assessment. A multivariate logistic regression model was used to analyze the association between urinary nickel level and diabetes risk. Multiple linear regression models were used to evaluate the association of urinary nickel level with HOMA-IR, HOMA-β and adjusted HOMA-β.Results:The sex ratio of controls and cases was 1∶1. The multivariate logistic regression model showed that after adjusting for factors such as education level, smoking status, alcohol consumption, rice and meat intakes, family history of diabetes, BMI, total cholesterol level, hypertension, and urinary creatinine, compared with T1 group, the ORs of diabetes risk in the T2 and T3 groups were 1.36 (95% CI: 0.98-1.89) and 1.60 (95% CI: 1.14-2.24), respectively. The multiple linear regression model showed a positive association between urinary nickel levels and the elevated HOMA-IR, the β value of HOMA-IR in the T3 group was 0.12 (95% CI: 0.01-0.25) compared with the T1 group and each one-unit increase in the log-transformed urinary nickel level (2.71 μg/L) was associated with a 0.06 elevation in HOMA-IR (95% CI: 0.02-0.10). Meanwhile, the urinary nickel levels were negative associated with the adjusted HOMA-β, the β value of adjusted HOMA-β in the T3 group were -0.26 compared with the T1 group (95% CI: -0.41- -0.11), and each one-unit increase in the log-transformed urinary nickel level (2.71 μg/L) was associated with a -0.09 decrease in adjusted HOMA-β(95% CI: -0.14- -0.04). Conclusion:Higher urinary nickel level is positively correlated with elevated insulin resistance and diabetes risk while negatively correlated with the function of pancreatic islet β cells in adults in China.
