Purpose To explore the application and clini-copathological significance of molecular classification in endome-trial cancer(EC)of WHO(2020)tumors of the female repro-ductive system.Methods Sixty-two EC patients were collected and categorized into four subgroups,namely POLE mutation type,mismatch repair deficient(MMRd)type,non-specific molecular spectrum(NMSP)type,and p53 mutation type,based on WHO molecular classification tested by PCR and im-munohistochemistry.The correlation among four molecular sub-groups and their clinicopathological features were analyzed.Re-sults The molecular classification was distributed as follows:3(4.8％)cases were POLE-mutated,15(24.2％)cases MMRd,36(58.1％)cases NSMP and 8(12.9％)cases p53 abnormal expression.There were no significant differences a-mong POLE-mutated and infiltration depth,grade,lymph vascu-lar space invasion and other pathological factors such as lymph node metastasis and FIGO stage(P＞0.05).Among 15 patients with MMRd,the proportion of FIGO stage Ⅱ+Ⅲ significantly increased.One case showed abnormal overexpression of p53 pro-tein,while two cases showed complete loss of expression in MMRd subgroup.36 cases of NSMP were associated with low histopathological grade(Grade Ⅰ+Ⅱ)(P＜0.05),and no significant differences were observed among NSMP and other clinicopathological factors(P＞0.05).The p53 abnormal ex-pression in 8 cases was related to high histopathological grade(Grade Ⅲ)(P＜0.05),and the rate of lymph node metastasis and FIGO stage Ⅱ+Ⅲ significantly increased in patients with p53 abnormal expression,and although the difference was not statistically significant(P＞0.05).Conclusion The molecu-lar subgroups of EC have certain clinical application value,the cases with MMRd and p53 abnormal expression may have poor prognosis than these with POLE-mutated and NSMP.

Objective To observe the therapeutic effect of extracorporeal shock wave therapy combined withsurface electromyography biofeedback training(ESW-sEMGBF)on post-traumatic elbow joint stiffness.Methods A total of 80 patients with post-traumatic elbow stiffness admitted to the Rehabilitation Department of Hangzhou Fuyang Hospital of Orthopedics of Traditional Chinese Medicine from January 2021 to December 2021 were randomly assigned into control group(n = 40)and treatment group(n = 40)using a lottery method.The control group received conventional rehabilitation treatment(including soft tissue release,joint mobilization,continuous passive motion and cold therapy),and the treatment group received conventional treatment combined with ESW-sEMGBF.Both groups underwent training once daily for five days a week over eight weeks.The visual analogue scale(VAS),active range of motion(AROM)of the elbow joint,and Mayo Elbow Performance Score(MEPS)were evaluated before and after treatment.Results After 8 weeks of treatment,significant improvements were observed in all outcomes for both groups.The treatment group showed better improvements in VAS scores,AROM,and MEPS after treatment compared with the control group(P<0.05,P<0.001,P<0.001).No side effects or adverse reactions were observed in either group after treatment.Conclusion Extracorporeal shock wave therapy combined with surface electromyography biofeedback training effectively alleviated pain in patients with post-traumatic elbow joint stiffness,improved elbow joint function,and increased active range of motion of the elbow joint.

The laccase (PpLAC) gene family members in peach fruit were identified and the relationship between their expression pattern and chilling induced browning were investigated. The study was performed using two varieties of peaches with different chilling tolerance, treated with or without exogenous γ-aminobutyric acid (GABA) during cold storage. Twenty-six genes were screened from the peach fruit genome. These genes were distributed on 6 chromosomes and each contained 5-7 exons. The PpLAC gene family members shared relatively similar gene structure and conserved motifs, and they were classified into 7 subgroups based on the cluster analysis. Transcriptome sequencing revealed that the expression levels of PpLAC7 and PpLAC9 exhibited an increasing pattern under low temperature storage, and displayed a similar trend with the browning index of peach fruit. Notably, GABA treatment reduced the degree of browning and inhibited the expression of PpLAC7 and PpLAC9. These results suggested that PpLAC7 and PpLAC9 might be involved in the browning of peach fruit during cold storage.

Objective: To investigate the risk factors affecting the short-term prognosis of patients with hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF), and establish a new scoring model to predict the short-term prognosis of patients. Methods: This study enrolled 222 patients with HBV-ACLF. According to their clinical outcomes during hospitalization and 90 days after discharge, they were divided into survival and death group. Clinical data were collected to calculate the Child-Turcotte-Pugh (CTP), model for end-stage liver disease (MELD), albumin-bilirubin (ALBI), and age-bilirubin-international normalized ratio-creatinine (ABIC) scores for prognosis. Multivariate logistic regression analysis was used to analyze the independent risk factors affecting 90-day mortality in HBV-ACLF patients. Cox regression model was used to establish a new prediction model. Area under the receiver operating characteristic curve was used to calculate short-term prognostic value of the models. K-M survival curve was used to predict the prognosis of patients. Results: CTP and ABIC scores were independent risk factors for 90-day mortality in HBV-ACLF patients, and the risk of death from liver failure had increased with increase of score. Cox regression model established a new predictive model CTP-ABIC = 0.551 × CTP + 0.297 × ABIC. Area under the receiver operating characteristic curve of all three scoring models (CTP, ABIC and CTP-ABIC) were 0.878, 0.829, 0.927, respectively. CTP-ABIC score was superior to the CTP and ABIC score (P value < 0.001). Patients with CTP-ABIC score ≥9.08 had higher mortality rate than patients with CTP-ABIC score < 9.08, and the difference was statistically significant (P < 0.001). Conclusion All three scoring systems can predict short-term prognosis in patients with HBV-ACLF, but the accuracy of CTP-ABIC is superior.

Objective To investigate the safety,feasibility and clinical application effect of upper arm totally implantable venous access port (TIVAP) inserted by the combination of oncologists and nurses in patients with tumor.Methods A total of 34 patients,who needed long-term transfusion treatment,were included in this study with upper arm TIVAP from March 2017 and December 2017.There were 20 males and 14 females.The median age was 63 (35 ～ 83) years.Upper arm TIVAP was implanted by both doctors and nurses into the patients with tumor,and the TIVAP related success rate,complications and patients satisfaction were recorded.Results 34 patients all succeeded in TIVAP implantation with the operation success rate of 100％.The average operation time was about 40 minutes (30 to 60 minutes) from the disinfecting cloth to the end of the suture.The operations of all patients were successful.After the operation two patients died of cancer progression,one patient had soft tissue infection around capsular bag,None of the patients had other complications such as blocked infusion,catheter shift,port reversal,and so on,and the incidence of complication was 2.94％ (1/34).Conclusions Upper arm TIVAP has the advantages of safe puncture,shorter operation time,few intra-operative and post-operative complications and higher feasibility for operation by both oncologist and nurse,which can supplement the limitations and deficiencies of the chest wall port and PICC in a certain extent,therefore is a good choice for clinical application.

To investigate the correlation of different types of urinary abnormalities or different proteinuria and hematuria with the pathological injury of kidney in IgA nephropathy with isolated hematuria and/or mild proteinuria.
 Methods: Patients with primary IgA nephropathy, isolated hematuria and/or mild proteinuria were enrolled in the Department of Nephrology, the Second Xiangya Hospital, Central South University from January 2013 to January 2018. According to the difference of red blood cell count in urinary sediment and quantitative of 24-hour urinary protein (24 h-UP) during renal biopsy, the patients were grouped in 3 ways: a simple hematuria group, a hematuria and proteinuria group, and a simple proteinuria group; a proteinuria I group, a proteinuria II group, and a proteinuria III group; a hematuria I group, a hematuria II group, and a hematuria III group. The clinical parameters such as age, mean arterial pressure, blood urea nitrogen, serum creatinine, blood uric acid, 24 h-UP, and renal pathological damage were compared.
 Results: A total of 157 patients met the inclusion criteria, including 71 males and 86 females. The most common pathological type was focal and/or segmental glomerulosclerosis. The Lee's classification were dominated by grade III and IV, and the renal pathological injury was heavy. Immunoglobulin deposition was dominated by simple IgA deposition. The most common fluorescence intensity of IgA deposition was +++. 97 (61.78%) patients were accompanied by complement deposition and were mainly composed of simple complement C3 deposition. There were 18 patients (11.47%) in the simple hematuria group, 111 patients (70.70%) in the hematuria and proteinuria group, and 28 patients (17.83%) in the simple proteinuria group. Compared with the simple hematuria group, the proportion of patients with mild injury was lower in the simple proteinuria group, and the proportion of patients with moderate-to-severe injuries was increased (χ2=7.053, P=0.008). Compared with the hematuria and proteinuria group, the proportion of patients with mild injury was lower in the simple proteinuria group, and the proportion of patients with moderate-to-severe injury was increased (χ2=4.294, P=0.038). Compared with the proteinuria I group, the proportion of patients with mild injury was lower in the proteinuria III group, and the proportion of patients with moderate-to-severe injury was increased (χ2=5.433, P=0.020). There was no significant difference in the proportion of patients with renal pathological injury among different hematuria groups (P>0.05).
 Conclusion: The clinical manifestations of patients with IgA nephropathy with hematuria and/or mild proteinuria are inconsistent with renal pathological damage. Some patients with mild clinical manifestations have severe renal pathological damage and the renal pathological damage is more serious in simple proteinuria. The more proteinuria, the heavier the renal pathological damage.

Objective To investigate the correlation between Hcy and blood lipid level and its diagnostic value in patients with cerebral infarction.Methods 218 patients with cerebral infarction were divided into the cerebral infarction group and no cercbral infarction group,based on the diagnosis results of head CT or MRI,and 60 healthy individuals were used as the control group.The levels of serum TC,TG,HDL-c,LDL-c and serum Hcy were determined in each group.The level of serum Hcy was used as a diagnostic-test and the criterion of cerebral infarction which was diagnosed by using head CT or MRI was used as a gold standard.Meanwhile,the sensibility,specificity,predictive value and likelihood ratio of Hcy were measured in patients with and without cerebral infarction.Results Levels of TC and Hcywere significantly elevated (P ＜ 0.01),but HDL-c level was significantly decreased in patients with and without cerebral infarction compared with the healthy people (P ＜ 0.05).Hcy level was shown negatively correlated with HDL-c (r =-0.144,P ＜ 0.05).The sensibility and specificity of Hcy in both two groups of patients with and without cerebral infarction were 42.20％ and 54.13％,the positive predictive value and negative predictive value of Hcy were 47.92％ and 48.36％,the positive likelihood ratio and negative likelihood ratio of Hcy were 0.92 and 1.07,respectively.Conclusion Hcy and blood lipid have definite correlation,but Hcy has low diagnostic value for cerebral infarction and may not be used as a biological marker for the cerebral infarction diagnosis.

Objective To investigate the expression of FZD7 (frizzled homolog protein7,FZD7) and IL-6 (interleukin-6,IL-6) in primary hepatocellular carcinoma(HCC) and the impact on the prognosis.Methods Immunohistochemistry(IHC) was used to detect the expression level of FZD7 and IL-6 in 68 HCC tissues,30 para-carcinoma tissues and 10 healthy controls from patients with hepatic hemangioma.Patients were followed-up for survival analysis.Results The expression ratio of FZD7 in HCC tissue,paracarcinoma tissue and healthy controls were 72％,53％ and 0 (P ＜ 0.001),the ratio of IL-6 expression was respectively 69％,57％ and 0 (P ＜0.001).The expressions of FZD7 were positively correlated with that of AFP level (x2 =7.059,P =0.035),pathology classification (x2 =4.732,P =0.043),and the infection of HBs (x2 =3.508,P =0.032).The overall survival (65 ％ vs.84％,x2 =5.525,P ＜ 0.05) and the disease free survival (33％ vs.75％,x2 =5.991,P ＜0.05) of HCC patients with co-positive was significantly lower than that with co-negative expression of FZD7 and IL-6.Conclusion FZD7 and IL-6 play a critical role in development and progression of HCC.

To observe different expression patterns of β-catenin and its clinical significance in colorectal cancer (CRC).Methods A total of 181 cases of CRC tissues and 30 cases of normal colorectal tissue were investigated by immunohistochemistry for the expression of β-catenin.Results The expression rate of β-catenin was 56.9％ (103/181) in CRC,and higher than that in normal colorectal tissue (P ＜ 0.05).The overexpression of nuclear β-catenin was significantly correlated with histological differentiation,lymph node metastasis and Dukes' stage in CRC (P ＜ 0.05),and no relationship with other pathological parameters,such as age,gender and the depth of infiltration.The incomplete membranous expression of β-catenin was significantly correlated with histological differentiation,the depth of infiltration,lymph node metastasis and Dukes' stage in CRC (P ＜ 0.05).The high expression of nuclear β-catenin related to histological differentiation and Dukes' stage in CRC (P ＜ 0.05).In the follow-up data of 82 cases of CRC,the expression of nuclear β-catenin was associated with poor prognosis,and the 5-year survival rate was significantly lower than that of self-control groups (P ＜ 0.05).Conclusion β-catenin plays important roles in colorectal carcinogenesis.Abnormal expression of β-catenin was related to the aggressive progression of CRC and may be helpful for evaluating the prognosis of patients with CRC.β-catenin is expected to become a new target for diagnosis and treatment of CRC in future.
