Fuzheng Huayu preparation (/) combined with tenofovir disoproxil fumarate on hepatitis B: a systematic review and Meta-analysis.

OBJECTIVE: To systematically evaluate the effectiveness of Fuzheng Huayu preparation (/, FZHY) plus tenofovir disoproxil fumarate (TDF) on hepatitis B. METHODS: Numerous databases - PubMed, Embase, Cochrane Library, China National Knowledge Infrastructure Database, WanFang Database, China Science and Technology Journal Database, and China Biological Medicine Database - were searched to identify the randomized controlled trials published from the inception of the database to November 2021. Two researchers independently conducted literature screening, data extraction, and bias risk assessment. RevMan 5.4 software was used for Meta-analysis. RESULTS: Eight studies involving 990 patients met the inclusion criteria in the current Meta-analysis. Levels of alanine transaminase, aspartate aminotransferase, total bilirubin, hyaluronic acid, type III procollagen, laminin, and type IV collagen after combination therapy were significantly lower than those after TDF therapy alone. However, albumin levels did not differ significantly between the two regimens. Subgroup analysis based on disease progression suggested that the combination therapy improved albumin levels in patients with chronic hepatitis B but not in patients with hepatitis B-related cirrhosis. Moreover, subgroup analysis based on treatment duration suggested that the albumin levels were increased and the type III procollagen levels were decreased with the > 24-week combination therapy but not with the ≤ 24-week combination therapy. CONCLUSIONS: A combination regimen of TDF and FZHY is more effective in treating hepatitis B than TDF alone. The combination therapy can effectively alleviate hepatic fibrosis and improve liver function. However, more standardized, high-quality studies with larger sample sizes are warranted to validate the study results.

Application of OrVil TM in patients with recurrent or denovo esophagogastric junction cancer / 中华普通外科杂志

Objective:To investigate the effect of transorally inserted anvil (OrVil TM) in patients with relapsed or denovo carcinoma at the esophagogastric junction. Methods:The clinical data of 60 patients who underwent radical intent resection for locally relapsed or denovo esophagogastric junction adenocarcinoma at Zhengzhou University Cancer Hospital from Jan 2011 to Jun 2021 were retrospectively analyzed. The patients were divided into two groups according to whether transorally inserted anvil was used. Twenty-six patients who had used the system were assigned to the experimental group. Thirty-four patients without transorally inserted anvil were set to control group.Results:The incisor distance of the experimental group was shorter than that of the control group [36(34-40)cm vs. 39(36-41)cm, Z=-4.948, P<0.05]. Operation time in experimental group was 177 (145-260) min, compared to control group of 172 (140-225) min ( Z=-0.735, P=0.463). Intraoperative blood loss was 200 (100-900) ml in the experimental group and 300 (100-800) ml in the control group ( Z=-1.244, P=0.213). Postoperative upper margin distance of the experimental group was (3.6±1.7) cm compared to control group of (1.8±1.1) cm ( t=-0.735, P<0.01). The positive rate of margin in the experimental group was 4% vs. 15% in the control group ( χ2=1.931, P=0.165). The length of postoperative hospital stay in the experimental group was (18.6±5.2) d vs. (20.5±4.7) d ( t=-1.455, P=0.151). Surgery-related complications developed in 19% in the experimental group vs. 27% in the control group ( P>0.05). Conclusion:The application of the transorally inserted anvil in the operation of patients with locally relapsed or denovo esophagogastric junction cancer after initial operation reduces the difficulty of operation and decreases the positive rate of margin.

The Role and Mechanism of CREBH Regulating SIRT3 in Metabolic Associated Fatty Liver Disease.

AIMS: To investigate the effect of cAMP response element-binding protein H (CREBH) on metabolic associated fatty liver disease by regulating sirtuin 3 (SIRT3). MAIN METHODS: Two mouse models of fatty liver induced by a methionine-choline deficient (MCD) diet and a high-fat (HF) diet and an in vitro model of palmitic acid (PA) induced lipid-overloaded hepatocytes were constructed to detect the expression of CREBH, SIRT3, total acetylation, and downstream protein interactions and lipid metabolism phenotype, which were further validated in CREBH-/- mice and lentivirus-overexpressing CREBH hepatocytes. KEY FINDINGS: In fatty liver and lipid overload models, the expressions of CREBH and SIRT3 were down-regulated and their expression was positively correlated, accompanied by an increase in the level of total protein acetylation. Overexpression of CREBH alleviated excess lipid accumulation, impaired viability, and the ability to metabolize energy through the fatty acid oxidation pathway in hepatocytes in vitro. Furthermore, overexpression of CREBH restored the interaction of the deacetylase SIRT3 with the molecules carnitine palmitoyl-transferase 2 (CPT2) and long-chain acyl CoA dehydrogenase (ACADL) involved in the fatty acid oxidation pathway and their deacetylation status. However, CREBH-/- aggravated the damage of lipid metabolism in the liver tissue of mice. SIGNIFICANCE: CREBH increased the enzymatic activity of downstream factors by positively regulating the expression of SIRT3, which promoted the oxidative decomposition of fatty acids in hepatocytes and played an important role in fatty acid oxidation in MAFLD.

Object:To investigate the impact of carbon nanoparticle tracing on the number of lymph nodes harvested in obese patients during radical gastrectomy for gastric cancer.Methods:Clinical data of 127 patients undergoing D 2 radical gastrectomy in the Affiliated Tumor Hospital of Zhengzhou University from Jan 2015 to Dec 2019 were retrospectively analyzed. According to whether the patients were injected with carbon nano particles during operation, they were divided into two groups: 64 patients without carbon nano particles during operation served as control group; 63 patients with carbon nano particles were included into experimental group. Results:The operation time of the control group was (160±31) min and that of the experimental group was (168±28) min ( t=-1.521, P=0.445). Intraoperative blood lose in the control group was (234±82) ml and that in the experimental group was (238±84) ml ( t=-0.295, P=0.846). The number of lymph nodes harvested in the first station, in the second station, the number of total lymph nodes and the number of lymph nodes with diameter <5 mm in the control group were less than those in the experimental group(10.4±3.8 vs. 24.5±10.6, t=-10.054),(6.6±2.8 vs. 16.8±7.3, t=-10.381),(17.1±6.4 vs. 41.2±17.6, t=-10.293),(3.9±2.5 vs. 21.2±9.1, t=-14.662) (all P<0.05), while the number of positive lymph nodes was not statistically different between the two groups all (5.9±6.2 vs. 4.2±3.4, t=-1.963, P>0.05). Black staining of lymph nodes in nano carbon group: 1 542 black stained lymph nodes were detected in the experimental group, the black staining rate of lymph nodes was 59.44% (1 542/2 594). Conclusion:Intraoperative application of carbon nanoparticles can significantly increase the number of harvested lymph nodes in obese (BMI≥25 kg/m 2) gastric cancer patients after radical resection.

MRI dynamic enhancement in defining the upper edge of adenocarcinoma of esophagogastric junction / 中华普通外科杂志

Objective:To investigate the clinical significance of MRI dynamic enhancement in defining the upper edge of adenocarcinoma of esophagogastric junction.Methods:The clinical data of 73 patients with adenocarcinoma on the esophagogastric junction operated from Jul 2018 to Aug 2019 in the Affiliated Cancer Hospital of Zhengzhou University were retrospectively analyzed. All patients underwent MRI examination within one week before surgery. First, the T 2WI, diffusion-weighted imaging and dynamic enhanced images of each patient were carefully observed to define the tumor location, size, shape, signal and enhancement mode, then the distances between the upper edge of the tumor and the cardiac incisure on MRI dynamic enhancement were measured independently, and compared with the measured distance in surgical fresh specimens. Results:The mean location of tumor upper edge measured in MRI of 73 patients was (1.75±1.98)cm, while measured in the surgical specimen was (1.72±1.97)cm. There was no significant difference between the two groups ( t=0.572, P=0.569). The intraclass correlation efficient between the two groups was excellent (ICC=0.974, 95% CI: 0.959-0.984, P<0.01). Conclusion:The measurement result of tumor upper edge in MRI is basically consistent with that of surgical specimens. MRI can be used to locate the tumor upper edge for adenocarcinoma of esophagogastric junction before operation.

A study on candidates benefiting from adjuvant chemotherapy in patients with pT1N1M0 gastric cancer / 中华普通外科杂志

Objective:To investigate whether adjuvant chemotherapy could be beneficial for patients with pT1N1M0 (stage ⅠB) gastric cancer.Methods:From Jan 2010 to Dec 2016, 185 patients with pT1N1M0 gastric cancer who were surgically resected at Henan Cancer Hospital were retrospectively analyzed. The patients were divided into chemotherapy group ( n=100) and non chemotherapy group ( n=85). Results:For disease-free survival (DFS) analysis, univariate survival analysis showed that age, examined lymph nodes, vascular invasion, nerve invasion and adjuvant chemotherapy were associated with DFS (all P<0.05); multivariate analysis showed that lymph node resection ≥ 16 ( HR=0.363, 95% CI: 0.160-0.827, P=0.016), vascular invasion ( HR=4.117, 95% CI: 1.796-9.436, P=0.001) and postoperative chemotherapy ( HR=4.530, 95% CI: 1.932-10.622, P=0.001) were independent risk factors for DFS. For disease-specific survival (DSS) analysis, univariate survival analysis showed that lymph node resection, vascular invasion, nerve invasion and adjuvant chemotherapy were associated with DSS; multivariate analysis showed that lymph node resection ≥ 16 ( HR=0.344, 95% CI: 0.144-0.822, P=0.016), vascular invasion ( HR=5.113, 95% CI: 2.029-12.887, P=0.001) and postoperative chemotherapy ( HR=4.694, 95% CI: 1.854-11.888, P=0.001)were independent risk factors for DSS. According to examined lymph nodes and vascular invasion , pT1N1M0 patients were divided into three risk categories (high, medium and low). DFS and DSS were significantly different among the three risk groups (all P<0.001, respectively). Conclusion:pT1N1M0 gastric cancer patients are expected to benefit from adjuvant chemotherapy. Patients with less than 16 lymph nodes and vascular invasion may be particularly suitable for adjuvant chemotherapy.

Objective:To investigate the application value of one-stitch prophylactic ileostomy in late ileostomy closure.Methods:The prospective randomized control study was conducted. The clinicopathological data of 141 patients with rectal cancer who underwent low anterior resection combined with prophylactic ileostomy in the Affiliated Tumor Hospital of Zhengzhou University from January 2016 to July 2020 were selected. There were 127 patients being selected after excluding 14 cases who did not undergo ileostomy closure. Patients undergoing one-stitch prophylactic ileostomy were divided into observation group, and patients undergoing traditional ileostomy were divided into control group. Observation indicators: (1) grouping situations of the enrolled patients; (2) surgical situations of ileostomy closure; (3) postoperative situations; (4) follow-up. Follow-up was conducted using outpatient examination and telephone interview once a month after low anterior resection combined with prophylactic ileostomy to detect complication and death of patients. The end point was at 3 months after ileostomy closure. The follow-up was up to July 2020. Measurement data with normal distribution were represented as Mean±SD, and comparison between groups was conducted using the independent sample t test. Measurement data with skewed distribution were represented as M( P25, P75) or M (range), and comparison between groups was conducted using the Mann-Whitney U test. Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test. Comparison of ordinal data between groups was conducted using the Mann-Whitney U test. Results:(1) Grouping situations of the enrolled patients: a total of 127 patients were selected for eligibility, aged from 31 to 83 years, with a median age of 64 years. Of 127 patients, there were 66 cases in observation group and 61 cases in control group. (2) Surgical situations of ileostomy closure: all patients from the two groups underwent ileostomy closure successfully. The incision length, operation time, volume of intraoperative blood loss, cases with abdominal adhesion degree as slight adhesion or obvious adhesion were 4.25 cm(4.00 cm, 5.00 cm), 48.00 minutes(33.75 minutes, 58.00 minutes), 30 mL(20 mL, 50 mL), 34, 32 of the observation group, versus 7.50 cm(7.00 cm, 8.50 cm), 70.00 minutes(57.00 minutes, 80.00 minutes), 30 mL(30 mL, 50 mL), 13, 48 of the control group, showing significant differences between the two groups ( Z=-9.549, -6.133, -2.758, χ2=12.405, P<0.05). (3) Postoperative situations: cases with incision infection of the observation group and the control group were 5 and 13, respectively, showing a significant difference between the two groups ( χ2=4.917, P<0.05). (4) Follow-up: all the 127 patients were followed up for 6-21 months, with a median follow-up time of 10 months. During the follow-up, 3 cases of the control group had postoperative incisional hernia and were cured after conservative treatment. None of patient had anastomotic leakage related complications or died during the follow-up. Conclusion:The one-stitch preventive ileostomy has the advantage of ileostomy closure, which can reduce the operation time, volume of intraoperative blood loss and shorten the incision length effectively, so as to reduce the incidence of postoperative incision infection related complications.

Surgical methods and clinical efficacy of different types of cesarean scar pregnancy / 中国基层医药

Objective:To compare surgical methods and clinical efficacy among different types of cesarean scar pregnancy (CSP).Methods:A total of 158 patients with CSP who received treatment in Yuncheng Central Hospital from January 2016 to June 2019 were included in this study. According to Expert Consensus on Diagnosis and Treatment of Cesarean Scar Pregnancy (2016 version), type I CSP was found in 55 patients, type II in 86 patients and type III in 17 patients. These patients were divided into groups A (ultrasound-guided suction curettage), B (uterine artery chemoembolization + ultrasound-guided suction curettage) and C (laparoscopic scar pregnancy lesion resection + scar repair) according to different surgical methods. The amount of intraoperative blood loss, the difference in human chorionic gonadotropin (HCG) level between before and after surgery, the time to postoperative HCG level returning to normal level, menstruation recovery, and re-pregnancy were compared between groups.Results:The amount of intraoperative blood loss in the groups A, B and C was (43.33 ± 72.31) mL, (34.41 ± 17.16) mL, (65.71 ± 70.52) mL, respectively. There was significant difference between groups ( F = 8.51, P = 0.014]. The difference in HCG level between before and after surgery in groups A, B and C was (0.64 ± 0.18), (0.79 ± 0.10), (0.76 ± 0.19), respectively. There was significant difference in the difference in HCG level between groups ( F = 19.21, P < 0.001). There was significant difference in the incidence of postoperative menstrual volume reduction between group B and the other two groups ( χ2 = 6.73, P = 0.003). After surgery, intrauterine pregnancy occurred in 12 patients, including 8 patients in group A (type I CSP in 2 patients, type II CSP in 3 patients, type III CSP in 3 patients), 4 patients in group B (type I CSP in 3 patients, type II CSP in 1 patient). Finally, full-term fetus delivery by cesarean section was performed in 6 patients (4 patients in group A and 2 patients in group B). Conclusion:Uterine artery chemoembolization combined with uterine curettage had less blood loss, during surgery and leads to an obvious decrease in HCG level, but it can result in reduction of menstrual volume. Ultrasound-guided suction curettage is preferred for type I and type II CSP. Balloon compression can be used to stop bleeding if massive bleeding occurs. Laparoscopic scar pregnancy lesion resection plus scar repair is recommended for type III CSP.

Mutant construction of HDA9 and its interactions with promoters of flowering integrator SOC1 and AGL24 in Brassica juncea / 生物工程学报

HDA9, a member of the deacetylase family, plays a vital role in regulating plant flowering time through flowering integrator SOC1 and AGL24. However, it remains elusive how HDA9 interacts with SOC1 and AGL24 in flowering time control. Here, HDA9 was cloned in Brassica juncea and then its three active sites were separately replaced with Ala via overlap extension PCR. Thus, mutants of HDA9(D172A), HDA9(H174A) and HDA9(D261A) were constructed and fused into the pGADT7 vector. The yeast one-hybrid assays indicated that HDA9 mutants remained the interactions with the promoters of SOC1 and AGL24. Furthermore, the aforementioned results were confirmed in the dual luciferase assays. Interestingly, the DNA-protein interactions were weakened significantly due to the mutation in the three active sites of HDA9. It suggested that flowering signal integrator SOC1 and AGL24 were regulated by the key amino acid residues of 172th, 174th and 261th in HDA9. Our results provide valuable information for the in-depth study of the biological function and molecular regulation of HDA9 in Brassica juncea flowering time control.

Efficacy and perioperative safety of FLOT regimen in neoadjuvant chemotherapy for gastric adenocarcinoma / 中华普通外科杂志

Objective:To evaluate the efficacy and perioperative safety of FLOT regimen in neoadjuvant chemotherapy for gastric adenocarcinoma.Methods:Data of 128 cases of neoadjuvant chemotherapy for gastric adenocarcinoma at the General Surgery Department of He′nan Cancer Hospital from Jan2018 to July 2019 were divided into FLOT group and SOX/XELOX group.Results:The disease control rate in the FLOT group was 81%, while that in the SOX/XELOX group was only 60% ( P=0.040). In terms of TRG classification and ypT staging, the proportion of TRG0 / 1 in the FLOT group was 49%, which was significantly higher than 21% in the SOX / XELOX group ( P=0.001). In the FLOT group, ypT 0-4 was 2, 10, 8, 17 and 6, respectively, while in the SOX/XELOX group, ypT 0-4 was 1, 9, 15, 26 and 34, respectively, ( P=0.022). In the FLOT group, ypTNM stages Ⅰ, Ⅱ, and Ⅲ were 11, 20, and 12, respectively, while in the SOX/XELOX group, ypTNM stages Ⅰ, Ⅱ, and Ⅲ were 12, 30, and 43, respectively ( P=0.040). Complications occurred in 10 patients (23%) in the FLOT group and 18 patients (21%) in the SOX/XELOX group ( P>0.05). Conclusions:FLOT neoadjuvant chemotherapy for advanced gastric adenocarcinoma does not increase the incidence of perioperative complications while effecting tumor regression and downstaging compared to SOX/XELOX regimen.

Fluorescent staining for the rapid diagnosis of rare invasive fungal infections / 中华微生物学和免疫学杂志

Objective To evaluate the performance of an enhanced fluorescent staining for the rapid diagnosis of invasive mycosis, especially rare cases, considering the traditional culture method always leads to delays in clinical diagnosis for its time consuming. Methods Cases of invasive mycosis identified by fluorescent staining in our hospital from September, 2017 to September, 2018 were retrospectively analyzed. Three rare in-vasive infections were reported in this study. Clinical specimens were pretreated using standard procedures and then smeared on slides along with the enhanced fluorescent dye. Species of the pathogens were identified accord-ing to their morphology under fluorescent microscope. The traditional culture method was used as a standard method to identify the pathogenic species based on their colony morphology, followed by PCR and sequencing analysis for further confirmation. Results Three cases of invasive mycosis caused by rare pathogens of Talaro-myces marneffei, Mucorales and Prototheca were rapidly diagnosed with the fluorescent staining method. Sequen-cing results indicated the species were Talaromyces marneffei, Rhizopus arrhizus and Prototheca wickerhamii. Conclusions Fluorescent staining is a rapid, economic and direct method for the diagnosis of invasive mycosis. The morphology of fungi is clear and easy to identify after fluorescence staining, which could be used for indica-tive diagnosis of highly suspected invasive mycosis and serve as an important complement to the traditional cul-ture method, especially for the diagnosis of rare or uncultured fungal pathogens.
