ABSTRACT

Objective To evaluate nPEP willingness and uptake among MSM in Shanghai. Methods MSM were recruited through a NGO-based HIV voluntary counseling testing clinic and several virtual communities using snowball sampling. Results A total of 606 MSM were successfully recruited in which 82.8% (502/606) had heard of nPEP and 81.2% (492/606) were willing to use nPEP. MSM who had been diagnosed with sexually transmitted diseases (STD) were more likely to hold willingness in using nPEP. High cost was the most common reason for being unwilling to use nPEP. 9.9% (60/606) had used nPEP in which 51.7% (31/60) had used twice or more, and 50%(30/60) had missed medication in the last nPEP. MSM who were heterosexual or with other sex orientations except for being bisexuality (OR=2.943, 95%CI: 1.057‒8.191), being receptor in anal intercourse (OR=3.361, 95%CI: 1.552‒7.282), having 2 or more sexual partners in the last 30 days (OR=2.242, 95%CI: 1.225‒4.105), having been diagnosed with STI (OR=2.317, 95%CI: 1.223‒4.389), and using drugs (OR=2.177,95%CI: 1.052‒4.503) were more likely to use nPEP. Conclusion MSM in Shanghai have a relatively high willingness to use and uptake of nPEP. Comprehensive strategies need to be developed on improving adherence and reducing HIV-risk behaviors.

ABSTRACT

Chimeric antigen receptor T (CAR-T) cell has achieved excellent efficacy in hematological tumors, especially for lymphoma. Many products have been approved to market all over the world, and 2 products targeting CD19 have been approved to treat relapsed and refractory large B-cell lymphoma in China. The current experiences of using CAR-T cells come from previous clinical studies. How to use CAR-T cells in a standardized and rationalized way is still a challenge faced by our clinicians. Based on the CAR-T cell treatment experiences from Peking University Cancer Hospital and the latest research progresses in CAR-T in China and abroad, this article will elaborate on patient screening, peripheral blood mononuclear cell collection, bridging treatment, lymphocyte depletion chemotherapy, CAR-T cell infusion, the monitoring and treatment of adverse events after infusion, and long-term follow-up after infusion, in order to guide clinicians to better use CAR-T cell and to bring maximum benefits to patients.

ABSTRACT

Objective:To investigate the effects of Huanglian Jiedutang on learning and memory ability and the cholinergic system in Alzheimer's disease(AD) rats induced by amyloid <italic>β</italic>-protein(A<italic>β</italic>)<sub>1-42</sub>. Method:Sixty male SD rats were divided into normal group, model group, huperzine A group (2.1×10<sup>-5</sup> g·kg<sup>-1</sup>), high-, medium- and low dose of Huanglian Jiedutang groups (6,3,1.5 g·kg<sup>-1</sup>). AD rat model was replicated by hippocampal injection of A<italic>β</italic><sub>1-42</sub>. After 4 weeks of treatment, Morris water maze test was performed. Hematoxylineosin (HE) staining was used to observe the pathological changes of rat hippocampus. Sampling blood from abdominal aorta was taken. Acetylcholine (ACh), acetylcholinesterase (AchE) and choline acetyltransferase (ChAT) in serum and hippocampus were detected by enzyme-linked immunosorbent assay (ELISA). The expression of hippocampal <italic>α</italic>7 nicotinic acetylcholine receptor (<italic>α</italic>7nAChR) protein was detected by Western blot. The expression of hippocampal <italic>α</italic>7nAChR mRNA was detected by Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR). Result:Compared with the normal group, there were obvious pathological changes in the model group,such as neuron necrosis in the cerebral cortex,pyramidal cell or granular cell necrosis in the hippocampus,disorder of arrangement and inflammatory cell infiltration,prolonged escape latency,decreased escape platform times,decreased residence time in the effective area and swimming path in the effective area (<italic>P<</italic>0.05,<italic>P<</italic>0.01). The contents of <italic>α</italic>7nAChR mRNA,ACh,AchE,ChAT,<italic>α</italic>7nAChR in the hippocampus decreased (<italic>P<</italic>0.01). Compared with the model group,the escape latency of the middle dose group was shorter (<italic>P<</italic>0.05), the escape platform times,the swimming path in the effective area and the residence time in the effective area increased (<italic>P<</italic>0.05,<italic>P<</italic>0.01), the contents of serum ACh,ChAT, hippocampal AchE,ChAT and <italic>α</italic>7nAChR increased (<italic>P<</italic>0.05,). The expression of hippocampal <italic>α</italic>7nAChR protein significantly increased (<italic>P<</italic>0.01), the residence time of effective area in high dose group was prolonged (<italic>P<</italic>0.01), the times of escape platform increased,and the contents of serum ACh,ChAT and hippocampal ACh,AchE,<italic>α</italic>7nAChR protein and <italic>α</italic>7nAChR mRNA increased (<italic>P<</italic>0.05). Conclusion:Huanglian Jiedutang can significantly improve the learning and memory ability of AD rats induced by A<italic>β</italic><sub>1-42</sub>,and its mechanism may be related to the improvement of cholinergic system damage and enhancement of cholinergic system function induced by A<italic>β</italic><sub>1-42</sub>.

ABSTRACT

Background@#Type 2 diabetes mellitus (T2DM) is characterized by elevated fasting glucagon and impaired suppression of postprandial glucagon secretion, which may participate in diabetic complications. Therefore, we investigated the associations of plasma glucagon with estimated glomerular filtration rate (eGFR), albuminuria and diabetic kidney disease (DKD) in T2DM patients. @*Methods@#Fasting glucagon and postchallenge glucagon (assessed by area under the glucagon curve [AUCgla]) levels were determined during oral glucose tolerance tests. Patients with an eGFR <60 mL/min/1.73 m2 and/or a urinary albumin-to-creatinine ratio (UACR) ≥30 mg/g who presented with diabetic retinopathy were identified as having DKD. @*Results@#Of the 2,436 recruited patients, fasting glucagon was correlated with eGFR and UACR (r=–0.112 and r=0.157, respectively; P<0.001), and AUCgla was also correlated with eGFR and UACR (r=–0.267 and r=0.234, respectively; P<0.001). Moreover, 31.7% (n=771) presented with DKD; the prevalence of DKD was 27.3%, 27.6%, 32.5%, and 39.2% in the first (Q1), second (Q2), third (Q3), and fourth quartile (Q4) of fasting glucagon, respectively; and the corresponding prevalence for AUCgla was 25.9%, 22.7%, 33.7%, and 44.4%, respectively. Furthermore, after adjusting for other clinical covariates, the adjusted odds ratios (ORs; 95% confidence intervals) for DKD in Q2, Q3, and Q4 versus Q1 of fasting glucagon were 0.946 (0.697 to 1.284), 1.209 (0.895 to 1.634), and 1.521 (1.129 to 2.049), respectively; the corresponding ORs of AUCgla were 0.825 (0.611 to 1.114), 1.323 (0.989 to 1.769), and 2.066 (1.546 to 2.760), respectively. Additionally, when we restricted our analysis in patients with glycosylated hemoglobin <7.0% (n=471), we found fasting glucagon and AUCgla were still independently associated with DKD. @*Conclusion@#Both increased fasting and postchallenge glucagon levels were independently associated with DKD in T2DM patients.

ABSTRACT

Objective:To evaluate the efficacy of comprehensive anti-cancer treatment for lung metastases after liver transplantation (LT) for hepatocellular carcinoma (HCC).Methods:From March 2012 to July 2016, A total of 36 patients with lung metastasis after LT were divided into comprehensive anti-cancer treatment group (rapamycin + radioactive I 125 seed implantation + pulmonary artery infusion chemotherapy + sorafenib, n=22) and maintenance supportive care group ( n=14). The survival profiles of two groups were evaluated. Results:No significant inter-group differences existed in preoperative basic data, tumor pathology, time of pulmonary metastatic tumor after operation and lung metastasis tumor burden.In comprehensive anti-cancer treatment group, there were partial remission ( n=3), disease stability ( n=12) and disease progression after treatment ( n=7). In maintenance supportive care group, there were disease stability ( n=3) and disease progression after treatment ( n=11). And comprehensive anti-cancer treatment was superior to maintenance supportive care ( χ2=7.901, P=0.019). The median survival time after metastasis was 23 months (95%CI: 19.68-26.32) in comprehensive anti-cancer treatment group and 7 months (95%CI: 3.33-10.67) in maintenance supportive care group; 1-year survival rate 91% and 9%, 2-year survival rate 45% and 0% and 3-year survival rate 10% and 0% respectively.The survival rate of comprehensive anti-cancer treatment group was significantly better than that of maintenance supportive care group ( P<0.001). Conclusions:Comprehensive anti-cancer treatment (rapamycin + radioactive I 125 seed implantation + pulmonary artery infusion chemotherapy + sorafenib) can improve the survival time of patients with lung metastasis after liver transplantation for HCC.

ABSTRACT

Objective:To evaluate the therapeutic effect of 177Lu-prostate specific membrane antigen (PSMA)-I&T on prostate cancer. Methods:The culture medium of 1.85, 18.50, 185.00, 555.00 and 925.00 MBq/L 177Lu-PSMA-I&T was added into LNCaP cells (200 μl/well, 5 experimental groups and 1 control group, 3 replicates in each group) for 24 h, and the cell viability in each group was detected. The culture medium of 3.7 MBq 177Lu-PSMA-I&T was added into LNCaP cells (1 experimental group, 1 control group, 3 replicates in each group) for 48 h to detect the changes of cell cycle. LNCaP cells (3 experimental groups and 1 control group, 3 replicates in each group) were added into the culture medium of 3.7, 19.5 and 37.0 MBq 177Lu-PSMA-I&T for 48 h to detect cell apoptosis. Tumor-bearing mice models were established (BALB/c-nu/nu nude mice, n=32). The changes of tumor volume and body mass of tumor-bearing mice were observed within 20 d after treatment. On the 7th day after treatment, tumor tissues of tumor-bearing mice were stained with HE staining and fluorescently stained with Ki-67 protein, and apoptosis was detected by TdT-mediated dUTP nick end labeling (TUNEL) assay. On the 20th day after treatment, pathological analysis was performed on the main viscera of the tumor-bearing mice. One-way analysis of variance, the least significant difference t test and paired t test were used to analyze the data. Results:Compared with the control group ((100.00±12.35)%), the cell survival rates were significantly decreased after 177Lu-PSMA-I&T intervention in 185.00, 555.00, 925.00 MBq/L groups ((57.56±6.35)%, (38.65±3.39)%, (27.95±4.48)%; F=78.91, t values: 8.312-14.106, all P<0.01). Cell survival rates were significantly reduced in 185.00 MBq/L group at different time points (24, 48 and 72 h; F=78.28, t values: 6.628-14.384, all P<0.01). The proportion of LNCaP cells in G2/M phase was increased from (12.36±0.28)% to (19.92±0.48)% ( t=17.180, P<0.01). The apoptosis rates of cells were significantly increased in 18.5 and 37.0 MBq groups ( F=71.86, t values: -6.138, -13.050, both P<0.05). The difference of relative tumor volume (RTV%) was statistically significant among 3.7, 14.8 and 29.6 MBq groups and control group (136.7±7.4, 59.2±23.8, 47.3±13.8 vs 240.3±3.7; F=78.20, t values: 7.549-13.345, all P<0.01). But there was no significant difference in body mass of tumor-bearing mice among groups. Compared with the control group, the positive rates of Ki-67 staining cells ((37.23±3.04)% vs (14.89±3.80)%, (5.60±1.83)%, (3.46±0.71)%) and TUNEL-fluorescein isothiocyanate (TUNEL-FITC) staining ((0.74±0.18)% vs (1.61±0.30)%, (3.19±0.44)%, (3.54±0.47)%) in tumor tissues of 3.7, 14.8 and 29.6 MBq groups were statistically significant ( F=103.91, t values: 10.429-15.762; F=38.66, t values: from -9.312 to -2.881, all P<0.01). Conclusions:177Lu-PSMA-I&T has a good therapeutic effect on prostate cancer, with no obvious therapeutic side effects. Therefore, 177Lu-PSMA-I&T is expected to be an ideal drug for treating prostate cancer.

ABSTRACT

Objective:To compare the treatment outcomes of neoadjoint therapy combined with liver transplantation versus radical hepatectomy for patients with surgically resectable hilar cholangiocarcinoma.Methods:A retrospective study was performed on the data of 64 patients with resectable hilar cholangiocarcinoma operated from January 2009 to December 2014 at the Organ Transplantation Department of the First Central Hospital of Tianjin. There were 43 males and 21 females, with an average age of 61.2 years. There were 45 patients who underwent radical hepatectomy in the liver resection group, and 19 patients who underwent combined neoadjuvant therapy (radiotherapy combined with 5-fluorouracil intravenous drip, transcatheter lumen radiotherapy, capecitabine oral administration) and liver transplantation in the liver transplantation group. The recurrence rates and survival rate were compared between groups.Results:The 1, 3 and 5 years cumulative survival rates of the liver transplantation group were 89.5%, 73.7% and 63.2%, respectively, which were significantly better than those of the liver resection group (80.0%, 53.3% and 35.6%) ( P<0.05). The postoperative tumor recurrence rate in the liver transplantation group was 31.6% (6/19), which was significantly lower than that in the liver resection group of 60.0% (27/45) ( P<0.05). Subgroup analysis using postoperative pathological results showed the cumulative survival rates of patients without lymph node metastasis (N 0) and those with negative resection margins (R 0) were not significantly different between groups ( P>0.05). However, for patients with regional lymph node invasion (N 1) and with R 0 resection margin, the cumulative survival rates at 1, 3 and 5 years after liver transplantation were 83.3%, 66.7% and 50.0%, respectively, which were significantly superior to the 64.3%, 28.6% and 14.3% of the liver resection group ( P<0.05). Conclusion:Hepatectomy is recommended for patients with N 0 R 0 resectable hilar cholangiocarcinoma. For patients with hilar cholangiocarcinoma with marginally resectable N 1R 0, neoadjuvant therapy combined with liver transplantation resulted in significantly better long-term overall survival than resection.

ABSTRACT

BACKGROUND@#It has been a global trend that increasing complications related to pelvic floor surgeries have been reported over time. The current study aimed to outline the development of Chinese pelvic floor surgeries related to pelvic organ prolapse (POP) over the past 14 years and investigate the potential influence of enhanced monitoring conducted by the Chinese Association of Urogynecology since 2011.@*METHODS@#A total of 44,594 women with POP who underwent pelvic floor surgeries between October 1, 2004 and September 30, 2018 were included from 22 tertiary academic medical centers. The data were reported voluntarily and obtained from a database. We compared the proportion of each procedure in the 7 years before and 7 years after September 30, 2011. The data were analyzed by performing Z test (one-sided).@*RESULTS@#The number of different procedures during October 1, 2011-September 30, 2018 was more than twice that during October 1, 2004-September 30, 2011. Regarding pelvic floor surgeries related to POP, the rate of synthetic mesh procedures increased from 38.1% (5298/13,906) during October 1, 2004-September 30, 2011 to 46.0% (14,107/30,688) during October 1, 2011-September 30, 2018, whereas the rate of non-mesh procedures decreased from 61.9% (8608/13,906) to 54.0% (16,581/30,688) (Z = 15.53, P < 0.001). Regarding synthetic mesh surgeries related to POP, the rates of transvaginal placement of surgical mesh (TVM) procedures decreased from 94.1% (4983/5298) to 82.2% (11,603/14,107) (Z = 20.79, P < 0.001), but the rate of laparoscopic sacrocolpopexy (LSC) procedures increased from 5.9% (315/5298) to 17.8% (2504/14,107).@*CONCLUSIONS@#The rate of synthetic mesh procedures increased while that of non-mesh procedures decreased significantly. The rate of TVM procedures decreased while the rate of LSC procedures increased significantly.@*TRIAL REGISTRATION NUMBER@#NCT03620565, https://register.clinicaltrials.gov.

ABSTRACT

Objective To investigate and analyze the incidence of hepatitis B virus (HBV) infection and related cirrhosis in a certain area. Methods A retrospective investigation was performed on 365 patients with HBV infection in a certain area from October 2018 to October 2020. The relevant data of the patients and the incidence of HBV infection-related cirrhosis were analyzed to explore the influencing factors for liver cirrhosis caused by HBV infection. Results The age of patients with HBV infection was mainly 31-50 years old (61.92%), who were mainly males (80.00%). The symptoms included yellow urine (66.30%), loss of appetitte (57.53%) and fatigue (46.85%). There was abnormal increase of aspartate aminotransferase and alanine aminotransferase, and hyperbilirubinemia in patients. 35 patients developed liver failure, of whcih 31 patients survived and were discharged, 3 patients underwent liver transplantation and 1 patient died after discharge. Among the 365 patients, there were 82 cases with HBV-related cirrhosis, mainly aged between 31 and 50 years old (63.41%), who were mainly males (80.00%). The main symptoms included abdominal distension (46.34%), liver palm (39.02%) and jaundice (34.15%), and all were accompanied with abnormal liver function indexes. Of the 365 patients, 35.37% of them were complicated with primary peritonitis, and 25.61% with electrolyte imbalance. In addition, 87.80% of the patients improved and were discharged. The incidence rates of upper gastrointestinal bleeding, hepatic encephalopathy and death were 7.32%, 3.66% and 1.22%, respectively. The results of univariate and multivariate analysis showed that drinking history, HBV-DNA level and exercise were the influencing factors of HBV-related cirrhosis (P<0.05). Conclusion Patients with HBV infection and related cirrhosis are mostly middle-aged men. Drinking history, HBV-DNA level and exercise are important influencing factors for HBV infection progression to cirrhosis.

ABSTRACT

Purpose@#The aim of this study was to compare the efficacy of liver transplantation (LT) and liver resection (LR) for hepatocellular carcinoma (HCC) patients with portal vein tumor thrombus (PVTT) and to investigate risk factors affecting prognosis. @*Materials and Methods@#A total of 94 HCC patients with PVTT type I (segmental PVTT) and PVTT type II (lobar PVTT) were involved and divided into LR (n=47) and LT groups (n=47). Recurrence-free survival (RFS) and overall survival (OS) were compared before and after inverse probability of treatment weighting (IPTW). Prognostic factors for RFS and OS were explored. @*Results@#Two treatment groups were well-balanced using IPTW. In the entire cohort, LT provided a better prognosis than LR. Among patients with PVTT type I, RFS was better with LT (p=0.039); OS was not different significantly between LT and LR (p=0.093). In subgroup analysis of PVTT type I patients with α-fetoprotein (AFP) levels >200 ng/mL, LT elicited significantly longer median RFS (18.0 months vs. 2.1 months, p=0.022) and relatively longer median OS time (23.6 months vs. 9.8 months, p=0.065). Among patients with PVTT type II, no significant differences in RFS and OS were found between LT and LR (p=0.115 and 0.335, respectively). Multivariate analyses showed treatment allocation (LR), tumor size (>5 cm), AFP and aspartate aminotransferase (AST) levels to be risk factors of RFS and treatment allocation (LR), AFP and AST as risk factors for OS. @*Conclusion@#LT appeared to afford a better prognosis for HCC with PVTT type I than LR, especially in patients with AFP levels >200 ng/mL.

ABSTRACT

Objective:To investigate the rehabilitation resources of community health centers in Shanghai. Methods:December, 2018, all 247 community health centers in 16 districts of Shanghai were investigated with Health Institution Questionnaires, including the number of rehabilitation personnel (physiatrician, physical therapists) and the number of rehabilitation beds, etc. Results:There were 152 physiatrician and 597 physical therapists in community health centers in Shanghai. The numbers of physiatrician and physical therapists per 1000 registered population were 0.01 and 0.04, and were 0.03 and 0.12 for per 1000 registered elderly population. There were 17 484 beds in community health centers, in which the rehabilitation beds were 1425, accounting for 8.15%. Besides, the numbers of rehabilitation beds per 1000 registered population and registered elderly population in Shanghai were 0.10 and 0.30. Conclusion:The development of community-based rehabilitation in Shanghai is unbalanced. There is lack of community-based rehabilitation resources, the supply of service is insufficient, and there is gap between supply and demand. It is suggested to strengthen the support to community-based rehabilitation, and improve the supply of community-based rehabilitation resources.

ABSTRACT

Objective::To explore the effect of Erjingwan on the biological basis of kidney yin deficiency Alzheimer' s disease(AD)rats induced by ovariectomy+ D-galactose combined with amyloid beta1-40 (Aβ1-40). Method::After ovariectomy, rats were randomly divided into five groups: model group, positive group, Erjingwan high, medium and low dose group, 11 rats in each group, and 11 rats in sham operation group. One week after operation, D-galactose was injected intraperitoneally for 7 weeks, and four weeks after operation, Aβ1-40 was injected unilaterally into hippocampus. The rats in model group and sham-operation group were given saline by intragastric administration 3 weeks after operation. The rats in high, middle and low dose groups of Erjingwan were given corresponding concentration (9.0, 4.5, 2.25 g·kg-1). The rats in positive control group were given Donepezil 1.0 mg·kg-1 with dosage of 10 mL·kg-1 once a day for 35 consecutive days. After 30 days of administration, the learning ability of the rats were examined using a Y-maze. The hippocampus tissues of rats were isolated. The morphology of hippocampus was observed by Nissl staining.The proteins were detected by Nanol-ESI liquid-mass spectrometry system and identified by protein Discovery software. Relative quantitative and qualitative analysis of differential proteins in hippocampus was performed by SIEVE software, and Gene Ontology of differential protein was performed by PANTHER Classification System database. String analysis and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway enrichment were performed on the differential proteins. Result::Compared with model group, the correct rate of Y maze in the high and middle dose groups of Erjingwan was significantly raised(P<0.05), and the number of neurons in the hippocampal CA1 area was significantly increased(P<0.01).115 differential proteins (Ratio>1.5 or Ratio<0.5) such as Insulin-like growth factor 1 receptors(IGF-1R) were found in the high-dose group of the Erjingwan group as well as 94 differential proteins such as Synaptophysin expressed in the middle-dose group of the Erjingwan. And there are 87 differential proteins such as Acetyl-CoA acetyltransferase-cytosolic in the positive drug group. It showed that these proteins were mainly divided into tubule-related proteins, heat shock proteins, energy metabolism-related proteins and AD-related proteins with GO analysis. It was found that the above differential proteins involved 93 signaling pathways such as Dopaminergic synaps by KEGG analysis. Conclusion::Erjingwan can improve cognitive impairment and neuronal damage in rats with kidney yin deficiency, possibly by altering the expression of multiple pathway-associated proteins such as phosphatidylinositol 3-kinase/protein kinase B signaling pathway(PI3K/Akt), insulin signaling pathway, and adenylate-activated protein kinase (AMPK)signaling pathway, estrogen signaling pathway, and Dopaminergic synapse.

ABSTRACT

<b>Objective::To study whether Sanhuang Xiexintang (SHXXT) can restore endothelial function by inhibiting the activation of NOD-like receptor protein 3 (NIRP3) induced by 7-ketocholesterol (7-keto) in vascular endothelial cells. <b>Method::The aortic rings of mice were cultured in normal group, model (7-keto) group, SHXXT groups (1%, 2% and 5% drug-containing serum). Vasodilation function of mice was observed. Microvascular endothelial cells were cultured according to the above experimental groups, and NIRP3 inhibitor isoglycyrrhizin (ISO) group, was also set. Western blot was used to detect the expressions of endothelial nitric oxide synthase (eNOS), NIRP3, cysteinyl aspartate specific proteinase-1 (Caspase-1), interleukin-1<italic>β</italic> (IL-1<italic>β</italic>) protein. In addition, nitric oxide (NO) quantitative kit was used to detect the concentration of NO. <b>Result::Compared with the normal group, the endothelium-dependent vasodilation function of vascular rings was significantly reduced in model group (<italic>P</italic><0.01), and the drug group significantly restored the endothelium-dependent vasodilation function in a concentration-dependent manner (<italic>P</italic><0.05, <italic>P</italic><0.01). Meanwhile, microvascular endothelial cells were also studied. Compared with the normal group, the content of eNOS protein in the model group decreased (<italic>P</italic><0.05), while the concentration of NO decreased significantly (<italic>P</italic><0.01). After treatment with SHXXT serum, eNOS and NO could be restored, with significant differences in the concentration of NO with 5% (<italic>P</italic><0.05) and 10% (<italic>P</italic><0.01) SHXXT serum. At the same time, the expressions of NIRP3 (<italic>P</italic><0.05), cle-Caspase-1 activation (<italic>P</italic><0.01) and IL-1<italic>β</italic> production (<italic>P</italic><0.01) in endothelium were significantly increased under 7-keto stimulation, and the SHXXT serum could significantly inhibit the expression and activation of relevant proteins. Subsequently, endothelial cells were treated with NIRP3 inhibitor ISO. Compared with the model group, eNOS expression increased, and NO concentration increased significantly (<italic>P</italic><0.01) after treatment with ISO, but ISO had no synergistic effect on SHXXT serum. <b>Conclusion::SHXXT can improve endothelium-dependent vascular dysfunction induced by 7-keto, which is achieved by NO signaling pathway mediated by inhibiting the activation of endothelial NIRP3-related proteins.

ABSTRACT

To scientifically evaluate the intervention effect of Chinese medicine preventive administration(combined use of Huo-xiang Zhengqi Oral Liquid and Jinhao Jiere Granules) on community population in the case of coronavirus disease 2019(COVID-19), a large cohort, prospective, randomized, and parallel-controlled clinical study was conducted. Total 22 065 subjects were included and randomly divided into 2 groups. The non-intervention group was given health guidance only, while the traditional Chinese medicine(TCM) intervention group was given two coordinated TCM in addition to health guidance. The medical instructions were as follows. Huoxiang Zhengqi Oral Liquid: oral before meals, 10 mL/time, 2 times/day, a course of 5 days. Jinhao Jiere Granules: dissolve in boiling water and take after meals, 8 g/time, 2 times/day, a course of 5 days, followed up for 14 days, respectively. The study found that with the intake of medication, the incidence rate of TCM intervention group was basically maintained at a low and continuous stable level(0.01%-0.02%), while the non-intervention group showed an overall trend of continuous growth(0.02%-0.18%) from 3 to 14 days. No suspected or confirmed COVID-19 case occurred in either group. There were 2 cases of colds in the TCM intervention group and 26 cases in the non-intervention group. The incidence of colds in the TCM intervention group was significantly lower(P<0.05) than that in the non-intervention group. In the population of 16-60 years old, the incidence rate of non-intervention and intervention groups were 0.01% and 0.25%, respectively. The difference of colds incidence between the two groups was statistically significant(P<0.05). In the population older than 60 years old, they were 0.04% and 0.21%, respectively. The incidence of colds in the non-intervention group was higher than that in the intervention group, but not reaching statistical difference. The protection rate of TCM for the whole population was 91.8%, especially for the population of age 16-60(95.0%). It was suggested that TCM intervention(combined use of Huoxiang Zhengqi Oral Liquid and Jinhao Jiere Granules) could effectively protect community residents against respiratory diseases, such as colds, which was worthy of promotion in the community. In addition, in terms of safety, the incidence of adverse events and adverse reactions in the TCM intervention group was relatively low, which was basically consistent with the drug instructions.

ABSTRACT

OBJECTIVE@#To transinfect SD adipose tissue-derived stem cell (ADSC) in vitro with a recombinant adenoviral vector containing human B-domain-deleted FVIII (BDDhFⅧ), so as to lay the foundation for the treatment of hemophilia A by using ADSC combined with BDDhFⅧ gene.@*METHODS@#ADSCs were isolated from the inguinal adipose tissue of SD rats and passed to third passage for identification. Third passage ADSCs were transfected in vitro with recombinant adenovirus vector Ad-BDDhFⅧ-GFP. The experiments were divided into Ad-BDDhFⅧ-GFP-transfected ADSCs group (A), Ad-GFP-transfected ADSC group (B), and untransfected ADSC group (C). CCK-8 method was used to detect the proliferation of transfected cells in three groups, and the expression level of hFⅧ antigen in cell supernatant was detected by ELISA. RT-PCR and Western blot respectively were used to detect the mRNA and protein expression of BDDhFⅧ in the three groups after transfection.@*RESULTS@#The growth curve of third passage cells isolated and cultured showed an inverted "S" shap; the flow cytometry detection showed the positive expression of CD29, CD90, CD44, and the negative expression of CD45 in third passage cells. After the adipogenic and osteogenic induction, the cells could transformed to adipogenic and osteogenic directions. CCK-8 detection showed that the proliferation of cells in 3 groups not was influenced. ELISA showed that the expression of hFⅧAg in group A was significantly higher than that in group B and C (P<0.05). RT-PCR showed that compared with group A, there was no target band in B and C groups, and BDDhFⅧ gene was not expressed. The results in group A were consistent with the length of amplified fragments, and BDDhFⅧ target gene was expressed. Western blot analysis showed that the expression of hFⅧ protein in group A was significantly higher than that in group B and C. (P<0.05).@*CONCLUSION@#Recombinant adenovirus Ad-BDDhFⅧ-GFP can effectively transfect rat ADSC in vitro, which lays an experimental foundation for gene therapy of hemophilia A.

ABSTRACT

Objective To compare the difference of clinical efficacy between surgical magnifying glass and surgical microscope assisted hepatic artery reconstruction in living donor liver transplantation (LDLT). Methods Clinical data of 272 donors and recipients undergoing LDLT were retrospectively analyzed. According to different patterns of hepatic artery reconstruction, all recipients were divided into the magnifying glass group (n=189) and microscope group (n=83). The operation time, intraoperative blood loss, hepatic artery reconstruction site, diameter of anastomosis, incidence of postoperative complications and survival rate of recipients were statistically compared between two groups. Results Compared with the microscope group, the operation time, hepatic artery reconstruction time and intraoperative blood loss were significantly less in the magnifying glass group (all P < 0.001). The most common site of hepatic artery reconstruction was the right hepatic artery in two groups, and the diameter of anastomosis was (2.1±0.9) mm in the magnifying glass group and (2.1±0.8) mm in the microscope group, with no statistical significance between two groups (P > 0.05). The 1-, 2- and 3-year survival rates of recipients in the magnifying glass group were 88%, 86% and 85%, which did not significantly differ from 89%, 87% and 86% in the microscope group (all P > 0.05). The incidence of postoperative complications did not significantly differ between two groups (all P > 0.05). Conclusions The efficacy and safety of hepatic artery reconstruction in LDLT under surgical magnifying glass are equivalent to those under surgical microscope, with less operation workload and intraoperative blood loss. For experienced transplantation surgeons, it is recommended to perform hepatic artery reconstruction assisted by surgical magnifying glass.

ABSTRACT

Liver transplantation is the most effective method for hepatitis B-related liver failure, liver cirrhosis and hepatocellular carcinoma. However, the reactivation of hepatitis B virus (HBV) after liver transplantation is not conducive to the recovery of liver function and leads to poor clinical prognosis. The prevention and treatment of HBV reactivation is currently the focus of research by physicians and surgeons. The current viral suppression strategies can not completely eradicate HBV nor completely prevent the recurrence of HBV infection in the future. This article aims to explore the molecular mechanism of HBV reactivation after liver transplantation, in order to more effectively prevent the recurrence of hepatitis B after liver transplantation.

ABSTRACT

Objective To explore the epidemiological characteristics of notifiable respiratory infectious diseases in Beijing from 2015 to 2018. Methods Descriptive epidemiological method was used to analyze the monitoring data of notifiable respiratory infectious diseases, and to describe the main characteristics of the diseases. Results Average annual reported incidence was 227.64/100 000, accounting for 36.24% of the total reports and deaths of notifiable infectious diseases. Class B and C respiratory infectious diseases showed a downward and upward trend respectively. The epidemic trend and risk population of the six major infectious diseases were different. Conclusions The incidence and mortality of legal respiratory infectious diseases in Beijing increases year by year due to the sharp increase of influenza from 2015 to 2018, and the responsibility of prevention and control is great. Respiratory infectious diseases have different epidemic season and predisposing population. Different prevention and control measures should be taken according to the different epidemic characteristics of different diseases.

ABSTRACT

Objective To analyze the spatial epidemiological characteristics of measles in Taizhou from 2009 to 2017, so as to provide theoretical basis for measles prevention and control. Methods The spatial autocorrelation analysis and trend surface analysis of measles epidemics data from 2009 to 2017 in Taizhou were performed using ArcGIS 10.0 software. The dynamic characteristics of measles epidemics in Taizhou were analyzed. Results Among 2009-2017 years, the incidences of measles in Taizhou ranged from 0.83/1 million to 65.43/1 million. The results of global autocorrelation analysis showed that there were spatial correlations of the incidence of measles among 2012, 2013, 2015, and 2016 in Taizhou with a high-value clustering distribution. Local autocorrelation analysis indicated that the hot spots of measles incidence in Taizhou from 2009 to 2017 were mainly concentrated in the central towns of Taizhou. Trend surface analysis suggested that the measles incidence in the south towns of Taizhou was higher than that in the north in 2010, and the incidence in the central region was higher than those in other regions in 2013 and 2015. Conclusions According to the spatial analysis, autocorrelation was observed for the spatial distribution of measles incidence in Taizhou from 2009 to 2017, and there are hot spots in the central township. Targeted preventive measures should be taken based on these characteristics.
