Abstract
Disturbances in intestinal immune homeostasis predispose susceptible individuals to type 1 diabetes (T1D). G-protein-coupled receptor 41 (GPR41) is a receptor for short-chain fatty acids (SCFAs) mainly produced by gut microbiota, which plays key roles in maintaining intestinal homeostasis. In this study, we investigated the role of GPR41 in the progression of T1D. In non-obese diabetic (NOD) mice, we found that aberrant reduction of GPR41 expression in the pancreas and colons was associated with the development of T1D. GPR41-deficient (Gpr41-/-) mice displayed significantly exacerbated streptozotocin (STZ)-induced T1D compared to wild-type mice. Furthermore, Gpr41-/- mice showed enhanced gut immune dysregulation and increased migration of gut-primed IFN-γ+ T cells to the pancreas. In bone marrow-derived dendritic cells from Gpr41-/- mice, the expression of suppressor of cytokine signaling 3 (SOCS) was significantly inhibited, while the phosphorylation of STAT3 was significantly increased, thus promoting dendritic cell (DC) maturation. Furthermore, adoptive transfer of bone marrow-derived dendritic cells (BMDC) from Gpr41-/- mice accelerated T1D in irradiated NOD mice. We conclude that GPR41 is essential for maintaining intestinal and pancreatic immune homeostasis and acts as a negative regulator of DC maturation in T1D. GPR41 may be a potential therapeutic target for T1D.

Abstract
OBJECTIVES To investigate the mechanism of electroacupuncture (EA) at "Neiguan" (PC6) in impro-ving myocardial electrical remodeling in rats with acute myocardial infarction (AMI) by enhancing transient outward potassium current. METHODS A total of 30 male SD rats were randomly divided into control, model and EA groups, with 10 rats in each group. The AMI model was established by subcutaneous injection with isoprenaline (ISO, 85 mg/kg). EA was applied to left PC6 for 20 min, once daily for 5 days. Electrocardiogram (ECG) was recorded after treatment. TTC staining was used to observe myocardial necrosis. HE staining was used to observe the pathological morphology of myocardial tissue and measure the cross-sectional area of myocardium. Potassium ion-related genes in myocardial tissue were detected by RNA sequencing. The mRNA and protein expressions of Kchip2 and Kv4.2 in myocardial tissue were detected by real-time fluorescence quantitative PCR and Western blot, respectively. RESULTS Compared with the control group, cardiomyocyte cross-sectional area in the model group was significantly increased (P<0.01), the ST segment was significantly elevated (P<0.01), and QT, QTc, QTd and QTcd were all significantly increased (P<0.05, P<0.01). After EA treatment, cardiomyocyte cross-sectional area was significantly decreased (P<0.01), the ST segment was significantly reduced (P<0.01), and the QT, QTc, QTcd and QTd were significantly decreased (P<0.01, P<0.05). RNA sequencing results showed that a total of 20 potassium ion-related genes co-expressed by the 3 groups were identified. Among them, Kchip2 expression was up-regulated most notablely in the EA group. Compared with the control group, the mRNA and protein expressions of Kchip2 and Kv4.2 in the myocardial tissue of the model group were significantly decreased (P<0.01, P<0.05), while those were increased in the EA group (P<0.01, P<0.05). CONCLUSIONS EA may improve myocardial electrical remodeling in rats with myocardial infarction, which may be related to its functions in up-regulating the expressions of Kchip2 and Kv4.2.

Abstract
Objective: To investigate the prevalence of syphilis in HIV-infected patients with transmission risk and influencing factors in Zhejiang Province. Method: The information about the HIV-infected patients, who were alive, had been diagnosed with HIV for >1 year, had received no antiviral treatment or had HIV viral load ≥50 copies/ml, and were aged ≥15 years, reported in Zhejiang as of December 31, 2018 were collected from China Information System for Disease Control and Prevention. The information included general demographic characteristics, sexual behavior characteristics and antiretroviral therapy and syphilis serological test results. The prevalence of syphilis and the influencing factors were analyzed by logistic regression model. The SPSS 19.0 software was used for statistical analysis. Results: A total of 2 275 HIV-infected patients were at risk of HIV transmission, and 75.5% (1 717/2 275) of them were tested for syphilis, the prevalence rate of syphilis was 8.7% (150/1 717). Among the HIV-infected patients with syphilis, 11.3% (17/150) received no antiviral treatment, 38.7% (58/150) had viral load of 50-999 copies/ml and 50.0% (75/150) had ≥1 000 copies/ml. Multivariate logistic regression analysis showed that being men (aOR=2.04, 95%CI:1.06-3.96), homosexual transmission (aOR=1.53, 95%CI:1.04-2.27), history of sexually transmitted diseases (STDs) before HIV diagnosis (aOR=1.98, 95%CI:1.35-2.92) and HIV viral load ≥1 000 copies/ml (aOR=1.90, 95%CI:1.09-3.30) were the risk factors for syphilis. Marriage (aOR=0.47, 95%CI: 0.29-0.76) was a protective factor for syphilis. Conclusions: The prevalence of syphilis was high in HIV-infected patients with transmission risk in Zhejiang. It is urgent to carry out classified management and targeted intervention in HIV-infected patients, explore multi-disease prevention and treatment mechanism, strengthen syphilis screening and treatment in HIV-infected patients to reduce the transmission of HIV and syphilis.

Abstract
Objective: To identify the transmission relationship between HIV infection cases the non-marital non-commercial heterosexual contact in Zhejiang Province. Methods: When HIV positive was informed during January 2020 to January 2022, the staff conducted an epidemiological investigation to collect cases information on sociodemographic characteristics, mobility information, past HIV testing history, high-risk sexual behaviors, sexual partners, and etcetera. At the same time, 6-8 ml of blood from the new diagnosis of people infected with HIV before antiviral treatment was collected to separate the bleeding plasma. pol gene was amplified by nucleic acid extraction and PCR, sequenced by Sequencer 5.0 software, and Cytoscape 3.6.0 software was used to draw HIV molecular transmission network. Results: From January 2020 to January 2022, 88 HIV infected individuals were found in Pujiang County, of which 74 were transmitted through heterosexual transmission, of which 31 were infected through non-marital non-commercial heterosexual contact. Preliminary case studies have found that three female cases have engaged in unprotected non-marital non-commercial heterosexual contact with one male case. Among the 4 infected individuals, 2 of their spouses tested positive for HIV antibodies. Molecular transmission network monitoring was carried out on 65 newly diagnosed cases of heterosexual transmission with acquired sequences, forming 9 transmission clusters. The largest cluster contained 10 cases. A total of 11 HIV-infected individuals were involved in this HIV cluster epidemic. They were 3 males and 8 females, all over 50 years old and were farmers or rural housewives. They were traced to 7 sexual partners (6 negatives of HIV, 1 undetected). Among the 18 respondents' sexual social network relationships, there were 6 couples, 8 permanent partners, and 3 temporary partners. Among 11 HIV infected individuals, there were 9 cases of non-marital non-commercial heterosexual transmission and 2 cases of intramarital transmission. The epidemiological association between 7 non-married non-commercial heterosexual partners and case 2 (56-year-old male farmer), 3 cases confirmed by epidemiological investigation and molecular transmission cluster results, 3 cases confirmed by molecular transmission cluster and epidemiological investigation results, and 1 case confirmed by epidemiological investigation results. Conclusions: The transmission mode of this cluster epidemic was to spread HIV through heterosexual sex with a male case as the core, then cause the transmission within marriage and between fixed sexual partners. The combination of epidemiological investigation and molecular transmission network traceability survey supports the conclusion of this study.

Abstract
Articular cartilage (AC) is most susceptible to degeneration in knee osteoarthritis (OA); however, the existing treatments for OA do not target the core link of the pathogenesis-"decreased tissue cell function activity and extracellular matrix (ECM) metabolic disorders" for effective intervention. iMSC hold lower heterogeneity and great promise in biological research and clinical applications. Rps6ka2 may play an important role in the iMSC to treat OA. In this study, the CRISPR/Cas9 gene editing Rps6ka2-/- iMSC were obtained. Effect of Rps6ka2 on iMSC proliferation and chondrogenic differentiation was evaluated in vitro. An OA model was constructed in mice by surgical destabilization of medial meniscus (DMM). The Rps6ka2-/- iMSC and iMSC were injected into the articular cavity twice-weekly for 8 weeks. In vitro experiments showed that Rps6ka2 could promote iMSC proliferation and chondrogenic differentiation. In vivo results further confirmed that Rps6ka2 could improve iMSC viability to promote ECM production to attenuate OA in mice.

Abstract
Long-term treatment with adriamycin (ADR) is associated with higher incidences of cumulative cardiotoxicity manifest as heart failure. ADR-induced cardiomyopathy is characterized by extensive fibrosis that is caused by cardiac fibroblast activation. To date, however, no specific treatment is available to alleviate ADR-induced cardiotoxicity. Protein arginine methyltransferase 5 (PRMT5), a major enzyme responsible for methylation of arginine, regulates numerous cellular processes such as cell differentiation. In the present study we investigated the role of PRMT5 in cardiac fibrosis. Mice were administered ADR (3 mg/kg, i.p., every 2 days) for 2 weeks. We showed that aberrant PRMT5 expression was largely co-localized with α-SMA-positive activated cardiac fibroblasts in ADR-injected mice and in ADR-treated cardiac fibroblasts in vitro. PRMT5-overexpression exacerbated, whereas PRMT5 knockdown alleviated ADR-induced cardiac fibrosis in vivo and TGF-β1-induced cardiac fibroblast activation in vitro. We demonstrated that PRMT5-overexpression enhanced methylated-Smad3 levels in vivo and in vitro. Pretreatment with a specific PRMT5 inhibitor EPZ015666 (5 nM) or overexpression of a catalytically inactive mutant of PRMT5, PRMT5(E444Q), reduced PRMT5-induced methylation of Smad3, thus suppressing PRMT5-mediated cardiac fibroblast activation in vitro. Furthermore, ADR activated cardiac fibroblasts was depending on autocrine TGF-β1. Taken together, our results demonstrate that PRMT5 promotes ADR-induced cardiac fibrosis via activating cardiac fibroblasts, suggesting that it may be a potential therapeutic target of ADR-caused cardiotoxicity.

Abstract
The microbial‑induced carbonate precipitation (MICP), as an emerging biomineralization technology mediated by specific bacteria, has been a popular research focus for scientists and engineers through the previous two decades as an interdisciplinary approach. It provides cutting-edge solutions for various engineering problems emerging in the context of frequent and intense human activities. This paper is aimed at reviewing the fundaments and engineering applications of the MICP technology through existing studies, covering realistic need in geotechnical engineering, construction materials, hydraulic engineering, geological engineering, and environmental engineering. It adds a new perspective on the feasibility and difficulty for field practice. Analysis and discussion within different parts are generally carried out based on specific considerations in each field. MICP may bring comprehensive improvement of static and dynamic characteristics of geomaterials, thus enhancing their bearing capacity and resisting liquefication. It helps produce eco-friendly and durable building materials. MICP is a promising and cost-efficient technology in preserving water resources and subsurface fluid leakage. Piping, internal erosion and surface erosion could also be addressed by this technology. MICP has been proved suitable for stabilizing soils and shows promise in dealing with problematic soils like bentonite and expansive soils. It is also envisaged that this technology may be used to mitigate against impacts of geological hazards such as liquefaction associated with earthquakes. Moreover, global environment issues including fugitive dust, contaminated soil and climate change problems are assumed to be palliated or even removed via the positive effects of this technology. Bioaugmentation, biostimulation, and enzymatic approach are three feasible paths for MICP. Decision makers should choose a compatible, efficient and economical way among them and develop an on-site solution based on engineering conditions. To further decrease the cost and energy consumption of the MICP technology, it is reasonable to make full use of industrial by-products or wastes and non-sterilized media. The prospective direction of this technology is to make construction more intelligent without human intervention, such as autogenous healing. To reach this destination, MICP could be coupled with other techniques like encapsulation and ductile fibers. MICP is undoubtfully a mainstream engineering technology for the future, while ecological balance, environmental impact and industrial applicability should still be cautiously treated in its real practice.

Abstract
OBJECTIVE The study explores the effects of electroacupuncture (EA) at the governing vessel (GV) on proteomic changes in the hippocampus of rats with cognitive impairment. METHODS Healthy male rats were randomly divided into 3 groups: sham, model and EA. Cognitive impairment was induced by left middle cerebral artery occlusion in the model and EA groups. Rats in the EA group were treated with EA at Shenting (GV24) and Baihui (GV20) for 7 d. Neurological deficit was scored using the Longa scale, the learning and memory ability was detected using the Morris water maze (MWM) test, and the proteomic profiling in the hippocampus was analyzed using protein-labeling technology based on the isobaric tag for relative and absolute quantitation (iTRAQ). The Western blot (WB) analysis was used to detect the proteins and validate the results of iTRAQ. RESULTS Compared with the model group, the neurological deficit score was significantly reduced, and the escape latency in the MWM test was significantly shortened, while the number of platform crossings increased in the EA group. A total of 2872 proteins were identified by iTRAQ. Differentially expressed proteins (DEPs) were identified between different groups: 92 proteins were upregulated and 103 were downregulated in the model group compared with the sham group, while 142 proteins were upregulated and 126 were downregulated in the EA group compared with the model group. Most of the DEPs were involved in oxidative phosphorylation, glycolipid metabolism and synaptic transmission. Furthermore, we also verified 4 DEPs using WB technology. Although the WB results were not exactly the same as the iTRAQ results, the expression trends of the DEPs were consistent. The upregulation of heat-shock protein β1 (Hspb1) was the highest in the EA group compared to the model group. CONCLUSION EA can effect proteomic changes in the hippocampus of rats with cognitive impairment. Hspb1 may be involved in the molecular mechanism by which acupuncture improves cognitive impairment.

Abstract
SCOPE Dietary fibers can alter gut microbiota and microbial metabolite profiles. SCFAs are produced by bacterial fermentation of fiber, mediating immune homeostasis through G-protein-coupled receptors (GPCRs). GPR109a, a receptor for niacin and butyrate, expressed by immune cells and non-immune cells, is a key factor regulating immune responses. However, the role and underlying mechanisms of GPR109a in type 1 diabetes (T1D) remain unclear. METHODS AND RESULTS Experimental T1D was induced by streptozotocin in GPR109a-deficient (Gpr109a-/- ) and wild type mice. The study found that Gpr109a-/- mice were more susceptible to T1D with dysregulated immune responses, along with increased M1 macrophage polarization (from 10.55% to 21.48%). Further, an adoptive transfer experiment demonstrated that GPR109a-deficient macrophages promoted the homing of intestine-derived type 1 cytotoxic T cells to pancreas (from 18.91% to 24.24%), thus disturbing the pancreatic immune homeostasis in non-obese diabetic mice. Mechanistically, GPR109a deficiency promoted M1 macrophage polarization associated with the activation of suppressor of cytokine signaling 3-signal transducer and activator of transcription 1 signaling pathway. CONCLUSION The findings reveal that macrophage GPR109a deficiency accelerates the development of T1D. Activation of GPR109a on macrophage by dietary components may provide a new strategy for preventing or treating T1D.

Abstract
Objective: To identify the status and determinants of sharing personal HIV information with sexual partners among men who have sex with men (MSM) meeting their casual sexual partners on the internet. Methods: A cross-sectional study was conducted in five cities (Hangzhou, Ningbo, Wenzhou, Taizhou and Shaoxing) in Zhejiang province. The recruitment was enrolled by MSM social organization and in voluntary counseling and testing clinics, with a sample size of 793. A self-designed network questionnaire collected essential characteristics, HIV knowledge, sexual behavior, and sharing personal HIV status. SPSS 20.0 software was used for statistical analysis. Results: Among 767 MSM enrolled 302 MSM who reported finding casual sexual partners on the internet were enrolled in the analysis. MSM reported finding casual partners on the internet only, finding sexual partners online and in places were 62.6% (189/302) and 37.4% (113/302), respectively. Among those reporting web-based sexual behavior in the last six months, 54.6% (165/302) informed their partners of their HIV status, 49.2% (146/297) inquired about HIV status, and 42.9% (82/191) knew HIV status before sex intercourse, 75.8% (113/149) reported consistent condom use with HIV negative partners. The multivariable logistic regression analysis showed that related factors of inconsistent inquired HIV status of partners included 25-34 years old (aOR=2.17, 95%CI: 1.20-3.91), >2 partners on the internet in the last six months (aOR=2.13, 95%CI: 1.27-3.57), low-risk perception of HIV infection with online partners (aOR=1.96, 95%CI:1.14-3.35), numbers of HIV testing >1 times (aOR=0.38, 95%CI: 0.22-0.66). Conclusions: The willingness to know the HIV status of partners among MSM who met sexual partners on the internet was high but with a low rate of knowing their sex partner's HIV status in Zhejiang province. However, the successful implementation proportion was low. Therefore, it is necessary to pay attention to people who are elderly, with less conscience about the risk of the sex partners on the internet, have more sex partners, and have received few HIV tests. In addition, peer education was needed to promote related intervention programs.

Abstract
BACKGROUND In most cases, it is not difficult to differentiate common left ventricular (LV) cardiac myxomas from fibromas because they are different disease entities and have different imaging findings. Herein, we present a case of a tumor with histological characteristics of a LV cardiac myxoma even though its imaging and macroscopical views were similar to that of fibroma. CASE PRESENTATION A 65-year-old woman was admitted to the hospital with chest tightness and palpitations which persisted for 2 years. Transthoracic echocardiogram and transesophageal echocardiography revealed a 23 mm × 8 mm, polyp-like-shaped, homogeneous, firm, solitary, mobile and solitary LV mass, which protruded into the left atrium during systole, resulting in mild mitral regurgitation. LV contrast-enhanced echocardiography revealed that there was little contrast agent filling in the LV mass. To further clarify the nature of the mass, non-enhanced and contrast-enhanced coronary computed tomography (CT) angiograms showed a 19 mm × 8 mm relatively homogeneous low density with punctate calcifications mass and no significant enhancement. Thus, we preoperatively diagnosed her condition as a LV fibroma and performed excision of the tumor under cardiopulmonary by-pass by using port-access approach through right mini-thoracotomy. The postoperative pathological diagnosis of the tumor was in fact a LV myxoma. CONCLUSIONS LV cardiac myxomas mimicking fibroma makes diagnosis difficult, and sonographers should be aware of this imaging changes.

Abstract
Objective: To investigate the impact of the iris and ciliary body morphology on the central vault after phakic posterior chamber intraocular lens (pIOL) implantation. Methods: This research was based on the retrospective analysis of 123 patients (123 eyes) who underwent pIOL implantation in the Department of Ophthalmology, Affiliated Hospital of Qingdao University between June 2018 and June 2020. The anterior segment structure was observed with an ultrasound biomicroscope before surgery, and all morphological parameters of the iris and ciliary body were measured manually using the ImageJ software, including iris span (IS), iris convexity (IC), iris-ciliary body contact distance (ICCD) and iris-lens contact distance (ILCD). The ICCD was divided into Q1, Q2 and Q3 groups according to the equidistant distance of 0.36 mm. The lens thickness was measured with the IOLMaster. The horizontal corneal diameter and anterior chamber depth were measured using the Pentacam. The central vaults were measured by optical coherence tomography at 1 week, 3 months and 1 year after surgery. The relationships between vault values and preoperative parameters of the anterior segment were evaluated using the Pearson correlation analysis, Spearman correlation analysis, and multiple linear regression. The repeated measures ANOVA was applied to identify changes of vault values over time. Results: The mean values of the vaults at 1 week, 3 months and 1 year after surgery were (723±265) μm, (642±255) μm and (613±280) μm, respectively. The difference among them was statistically significant (F=50.143, P<0.001). The vaults continued to decline within 1 year after pIOL implantation, and the total decline was (122±86) μm. The vaults declined by (69±98) μm from postoperative 1 week to 3 months and by (52±54) μm from postoperative 3 months to 1 year. The regression formula showed that the pIOL size and ILCD were positively related with the vault, while the LT, IS and IC were negatively related with the vault at 1 week postoperatively (adjusted R²=0.404, P<0.001). The pIOL size and ILCD were positively related with the vault, while the IS and IC were negatively related with the vault at 3 months postoperatively (adjusted R²=0.342, P<0.001). The pIOL size was positively related with the vault, while the IS and IC were negatively related with the vault at 1 year postoperatively (adjusted R²=0.661, P<0.001). The vault values were higher in group Q3 compared to group Q1 at every timepoint, and the vault value was higher in group Q2 compared to Q1 at 1 year postoperatively. Conclusions: In the early postoperative period, eyes with a larger pIOL, shorter iris span, longer contact distance between the iris and ciliary body, and longer contact distance between the iris and lens were associated with a higher rate of excessive vaults. Meanwhile, eyes with a thicker lens and larger iris reverse convexity were more likely to obtain insufficient vaults. Within one year after surgery, the pIOL size, IS, IC and ICCD continued to impact on the vault. The ICCD, ILCD and IC can reflect the posterior chamber volume and change the haptic location and force, thus affecting the vault.

Abstract
AIMS Treatment for delayed wound healing resulting from peripheral vascular diseases and diabetic foot ulcers remains a challenge. A novel surgical technique named 'tibial cortex transverse transport' (TTT) has been developed for treating peripheral ischaemia, with encouraging clinical effects. However, its underlying mechanisms remain unclear. In the present study, we explored the potential biological mechanisms of TTT surgery using various techniques in a rat TTT animal model. METHODS A novel rat model of TTT was established with a designed external fixator, and effects on wound healing were investigated. Laser speckle perfusion imaging, vessel perfusion, histology, and immunohistochemistry were used to evaluate the wound healing processes. RESULTS Gross and histological examinations showed that TTT technique accelerated wound closure and enhanced the quality of the newly formed skin tissues. In the TTT group, haematoxylin and eosin (H&E) staining demonstrated a better epidermis and dermis recovery, while immunohistochemical staining showed that TTT technique promoted local collagen deposition. The TTT technique also benefited to angiogenesis and immunomodulation. In the TTT group, blood flow in the wound area was higher than that of other groups according to laser speckle imaging with more blood vessels observed. Enhanced neovascularization was seen in the TTT group with double immune-labelling of CD31 and α-Smooth Muscle Actin (α-SMA). The number of M2 macrophages at the wound site in the TTT group was also increased. CONCLUSION The TTT technique accelerated wound healing through enhanced angiogenesis and immunomodulation.

Abstract
OBJECTIVE To evaluate the effects of interactive dynamic scalp acupuncture (IDSA), simple combination therapy (SCT), and traditional scalp acupuncture (TSA) on motor function and gait of the lower limbs in post-stroke hemiplegia patients. METHODS A total of 231 patients with post-stroke hemiplegia was randomly divided into IDSA (78 cases), SCT (78 cases), and TSA (75 cases) groups by a random number table. Scalp acupuncture (SA) and lower-limb robot training (LLRT) were both performed in the IDSA and SCT groups. The patients in the TSA group underwent SA and did not receive LLRT. The treatment was administered once daily and 6 times weekly for 8 continuous weeks, each session lasted for 30 min. The primary outcome measures included Fugl-Meyer assessment of the lower extremity (FMA-LE), berg balance scale (BBS), modified barthel index (MBI), and 6-min walking test (6MWT). The secondary outcome measures included stride frequency (SF), stride length (SL), stride width (SW), affected side foot angle (ASFA), passive range of motion (PROM) of the affected hip (PROM-H), knee (PROM-K) and ankle (PROM-A) joints. The patients were evaluated before treatment, at 1- and 2-month treatment, and 1-, and 2-month follow-up visits, respectively. Adverse events during 2-month treatment were observed. RESULTS Nineteen patients withdrew from the trial, with 8 in the IDSA and 5 in the SCT groups, 6 in the TSA group. The FMA-LE, BBS, 6MWT and MBI scores in the IDSA group were significantly increased after 8-week treatment and 2 follow-up visits compared with the SCT and TSA groups (P<0.05 or P<0.01). Compared with pre-treatment, the grade distribution of BBS and MBI scores in the 3 groups were significantly improved at 1, 2-month treatment and 2 follow-up visits (P<0.05 or P<0.01). The SF, PROM-H, PROM-K and PROM-A in the IDSA group was significantly increased compared with the SCT and TSA groups after 8-week of treatment (P<0.05 or P<0.01). Compared with the SCT group, ASFA of the IDSA group was significantly reduced after 8-week of treatment (P<0.05). SF, SL, PROM-K and PROM-A were significantly increased at the 2nd follow-up visit whereas the ASFA was significantly reduced in the IDSA group compared with the SCT groups at 1st follow-up visit (P<0.05 or P<0.01). The SF was significantly increased in the SCT group compared with the TSA group after 8-week treatment (P<0.05). Compared with the TSA group, PROM-K, PROM-A were significantly increased at the 2nd follow-up visit (P<0.05). CONCLUSIONS The effects of IDSA on lower-limb motor function and walking ability of post-stroke patients were superior to SCT and TSA. The SCT was comparable to TSA treatment, and appeared to be superior in improving the motion range of the lower extremities. (Registration No. ChiCTR1900027206).

Abstract
Objective: To investigate the relationship between HIV-infected men who have sex with men and their sexual partners in Zhejiang province. Methods: A cross-sectional survey was conducted to recruit newly confirmed HIV/AIDS among MSM from 2015 to 2017, including sexual partner identification and molecular epidemiological study. Plasma was collected to extract RNA, and the pol gene of HIV-1 was amplified by RT-PCR/nested PCR. Phylogenetic tree and molecular transmission cluster were analyzed to identify the transmission relationship between sexual partners. Results: A total of 937 HIV/AIDS among MSM were recruited to promote HIV testing for their sexual partners, and 173 positive sexual partners were identified. 50.8% (61/120) of the gene sequences were clustered among the positive sex partners. Seven pairs of clustered sex partners combined with the results of recent infection preliminarily determined the transmission direction. In the clusters, there were statistical differences between the partners who were diagnosed in the same year (OR=12.190, 95%CI: 1.563-95.054) or with current residence in the different districts (OR=17.054, 95%CI: 1.742-166.982). Conclusions: Combined with a molecular transmission network, HIV test for the sexual partners of HIV/AIDS among MSM can improve the accurate tracking of cases and preliminarily determine the direction of transmission, according to the results of recent infection. It is suggested that after HIV is confirmed for HIV/AIDS among MSM, HIV tests should be carried out as soon as possible for their sexual partners, including a cross-regional sexual partner tracking test, which is helpful to improve the tracing procedure.

Abstract
Objective: To analyze the relationship between infection and transmission of HIV/AIDS, explore the characteristics of the HIV-1 transmission network, and provide evidence for formulating targeted prevention and control measures. Methods: The newly confirmed HIV/AIDS in Jiaxing from 2017 to 2018 were selected for the study. The sociodemographic and infection transmission-related information was gathered. The blood samples were collected and RNA was extracted, RT-PCR and nested PCR amplified the pol gene of HIV-1. The phylogenetic tree was constructed by Mega 6.0 software for subtype analysis. The genetic distance between strains was calculated, and the molecular transmission network was drawn by using Cytoscape 3.6.0 software. The results of the epidemiological study based on the molecular transmission network were analyzed. Results: There were fifteen HIV-1 gene subtypes in 517 cases of HIV/AIDS. The main subtypes were CRF01_AE (37.1%)、CRF07_BC (36.2%) and CRF08_BC (11.8%). Under the 1.0% gene distance threshold, 87 molecular clusters were established, and the total clustering rate was 45.8% (237/517). The cluster risk factors were 60-81 age group (compared with 14-24 age group, OR=2.690, 95%CI:1.058-6.844), married (compared with unmarried, OR=1.698, 95%CI:1.003-2.875), CRF07_BC subtype (compared with CRF01_AE, OR=2.203, 95%CI:1.426-3.404). The largest molecular cluster, CRF07_BC-1, consisted of 50 cases (including 21 cases confirmed in 2017 cases and 29 confirmed in 2018). Multivariate analysis showed that characteristics of unmarried (compared with married, OR=2.482, 95%CI:1.140-5.402), gays (compared with heterosexual, OR=3.163, 95%CI:1.543-6.483), cases with high-risk transmission (compared with other cases, OR=7.631, 95%CI:1.783-32.654), confirmed in Nanhu and Pinghu districts of Jiaxing (compared with other districts, OR=2.225, 95%CI:1.074-4.608) were risks for entering the largest molecular cluster. There were seven suspected high-risk transmission MSM in the largest molecular cluster. The first debut of homosexual behavior was from 2010 to 2018, and the median number of gay partners was 20 (P25, P75:10, 100) within two years before being diagnosed. Six reported a recent history of looking for gay partners in an MSM dating place in Nanhu district. Conclusions: The HIV-1 subtypes of newly confirmed HIV/AIDS were diverse, mainly sporadic in Jiaxing from 2017 to 2018. There were geographical aggregation characteristics and suspected some high-risk transmission cases, suggesting that rapid transmission and targeted intensive intervention are needed.

Abstract
OBJECTIVE To compare the clinical effects of interactive dynamic scalp acupuncture (IDSA), simple combination therapy (SCT), and traditional scalp acupuncture (TSA) on cognitive function, depression and anxiety in patients with post-stroke cognitive impairment. METHODS A total of 660 patients with post-stroke cognitive impairment who were admitted to 3 hospitals in Shenzhen City between May 2017 and May 2020 were recruited and randomly assigned to the IDSA (218 cases), SCT (222 cases) and TSA groups (220 cases) according to a random number table. All the patients received conventional drug therapy for cerebral stroke and exercise rehabilitation training. Scalp acupuncture and computer-based cognitive training (CBCT) were performed simultaneously in the IDSA group, but separately in the morning and in the afternoon in the SCT group. The patients in the TSA group underwent scalp acupuncture only. The course of treatment was 8 weeks. Before treatment (M0), 1 (M1) and 2 months (M2) after treatment, as well as follow-up at 1 (M3) and 2 months (M4), the cognitive function of patients was assessed using the Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment Scale (MoCA) Scales; depression, anxiety, sleep quality, and self-care ability of patients were assessed using Hamilton Depression Rating Scale (HAMD), Hamilton Anxiety Rating Scale (HAMA), Pittsburgh Sleep Quality Index (PSQI), and Modified Barthel Index (MBI), respectively. During this trial, all adverse events (AEs) were accurately recorded. RESULTS There were no significant differences in the MMSE, MoCA, HAMD, HAMA, PSQI, and MBI scores among the 3 groups at M0 (all P>0.05). In the IDSA group, the MMSE, MoCA and MBI scores from M2 to M4 were significantly higher than those in the SCT and TSA groups, while the HAMD, HAMA and PSQI scores were significantly reduced (all P<0.01). The changes of all above scores (M2-M0, M4-M0) were significantly superior to those in the SCT and TSA groups (all P<0.01, except M4-M0 of HAMD). At M2, the severity of MMSE, HAMD, HAMA, PSQI and MBI in the IDSA group was significantly lower than that in the SCT and TSA groups (all P<0.01). There was no serious AE during this trial. CONCLUSIONS IDSA can not only significantly improve cognitive function, but also reduce depression, anxiety, which finally improves the patient's self-care ability. The effect of IDSA was significantly better than SCT and TSA. (Trial registration No. ChiCTR1900027206).

Abstract
Objective: To understand the epidemiological characteristics and transmission routes of newly reported HIV/AIDS cases with non-martial and non-commercial (NMNC) heterosexual behaviors in Zhejiang province. Methods: A retrospective survey was conducted among HIV/AIDS cases that had NMNC heterosexual behavior history and diagnosed with HIV infection in Zhejiang between January 1st, 2017 and September 30th, 2019. The multiple correspondence analysis (MCA) was used to explore the association of social demographic characteristics with NMNC heterosexual partner types in the cases. Results: A total of 406 participants with NMNC heterosexual behaviors before HIV diagnoses were recruited in this study. Most of them were males (67.2%, 273/406), aged 25-49 years at HIV diagnoses (59.1%, 240/406). Prior to HIV infection confirmation, 36.0% (146/406) participants only had casual sexual partners, 52.0% (211/406) only had regular sexual partners, and 12.0% (49/406) had both. Statistical differences in marital status, occupation and income level were found among participants with different types of NMNC heterosexual partners (all P<0.05). Result of MCA indicted that monthly income ≤3 000 yuan RMB, self-employed, being married were only associated with casual NMNC heterosexual partner; working in service industry, education level of junior high school were only associated with regular heterosexual partner; working in enterprise, high school education level or above, monthly income ≥5 000 yuan RMB were associated with both casual and regular sexual partner. Conclusion: The HIV/AIDS cases with NMNC heterosexual behaviors before HIV diagnoses accounted for a large proportion in Zhejiang province during 2017-2019. Active intervention efforts should be made to improve the health awareness of the public to reduce the risk behaviors for HIV transmission.

Abstract
Troxerutin (TRX), a semi-synthetic derivative of the natural bioflavonoid rutin, is a bioactive flavonoid widely abundant in various fruits and vegetables. Known as vitamin P4, TRX has been demonstrated to have several activities including anti-inflammation, anti-oxidants, vasoprotection, and immune support in various studies. Although rutin, the precursor of troxerutin, was reported to have a protective role against bone loss, the function of TRX in skeletal system remains unknown. In the present study, we found that TRX promoted osteogenic differentiation of human mesenchymal stem cells (MSCs) in a concentration-dependent manner by stimulating the alkaline phosphatase (ALP) activity, calcium nodule formation and osteogenic marker genes expression in vitro. The further investigation demonstrated that TRX stimulated the expression of the critical transcription factor β-catenin and several downstream target genes of Wnt signaling, thus activated Wnt/β-catenin signaling. Using a femur fracture rats model, TRX was found to stimulate new bone formation and accelerate the fracture healing in vivo. Collectively, our data demonstrated that TRX could promote osteogenesis in vitro and facilitate the fracture healing in vivo, indicating that TRX may be a promising therapeutic candidate for bone fracture repair.

Abstract
Objective: To analyze the willingness of post-exposure prophylaxis (PEP) to prevent HIV transmission and related factors in men who have sex with men (MSM). Methods: Cross sectional survey design was used in this study. After informed consent, MSM aged 18 years or above and having had homosexual anal or oral sex in the past 6 months were recruited through "i WeChat" official account between September and November, 2019. Results: Of 1 517 MSM were surveyed, the proportion of MSM who had ever heard of PEP were 72.5% (1 100/1 517) and 87.9%(1 333/1 517) of the MSM said they would like to use PEP if it is needed.Multivariate logistic regression analysis suggested that aged above 25 year (OR=1.807, 95%CI: 1.090-2.995), HIV test history (OR=1.953, 95%CI: 1.171-3.256) and being aware of PEP (OR=2.163, 95%CI: 1.468-3.186) were the positive factors for PEP use, but an aware of the HIV status of sexual partner was the negative factor for PEP (OR=0.602, 95%CI: 0.407-0.890). Among MSM who had ever heard of PEP, the positive factors for PEP use included living in Zhejiang (OR=1.942, 95%CI: 1.097-3.438), aged above 25 years (OR=2.431, 95%CI: 1.331-4.439), being aware of PEP (OR=3.714, 95%CI: 1.532-9.007) obtaining information about PEP service from MSM organization/volunteer/health organization. Conclusions: MSM's willingness to use PEP services was relatively high. Age, awareness of PEP related knowledge, and awareness of sexual partner's HIV infection status were the related factors. MSM organization/volunteer/health organization were the main forces for PEP promotion in MSM.

Abstract
Potentiation of receptor activator of NF-κB ligand (RANKL)-induced osteoclastogenesis by IgG immunocomplexes (ICs) is generally considered an important pathway leading to cartilage and bone destruction in rheumatoid arthritis (RA). However, whether IgG ICs possess pro-osteoclastogenic potential independent of RANKL and inflammatory cytokines is unclear. Here we demonstrate that by fully cross-linking human FcγRIIa (hFcγRIIa) or co-ligating hFcγRIIa and TLR4, IgG ICs alone could drive the differentiation of human blood monocytes into nuclear factor of activated T cells cytoplasmic 1 (NFATc1-negative nonclassical osteoclasts (NOCs). Surprisingly, IgG ICs could also overrule RANKL-induced classical osteoclast (COC) differentiation in vitro. In mouse model of collagen-induced arthritis, hFcγRIIa-transgenic, but not nontransgenic control, mice suffered from cartilage/bone destruction accompanied by the presence of NFATc1- NOCs lining the eroded cartilage surface in affected joints. Our results not only identify a novel subset of IC-induced NOCs but also provide a possible explanation for the uncoupling of FcγR-mediated cartilage destruction from RANKL-related bone erosion in autoinflammatory arthritis. © 2021 American Society for Bone and Mineral Research (ASBMR)..

Abstract
OBJECTIVE To compare the efficacy of scalp acupuncture combined with lower-limb intelligent feedback training and lower-limb intelligent feedback training alone for lower-limb motor dysfunction after stroke. METHODS A total of 154 patients with lower-limb motor dysfunction after stroke were randomly divided into an observation group (76 cases, 6 cases dropped off) and a control group (78 cases, 8 cases dropped off). The patients in both groups were treated with conventional medication and exercise rehabilitation training. In addition, the patients in the observation group were treated with scalp acupuncture combined with lower-limb intelligent feedback training. The scalp acupuncture was given at upper 1/5 of the anterior oblique line of parietal temporal area and upper 1/5 of the posterior oblique line of parietal temporal area. The patients in the control group were treated with lower-limb intelligent feedback training alone. All the treatment was given once a day, 6 days a week, totaling for 8 weeks. The affected-side lower-limb Brunnstrom stage and modified Ashworth scale (MAS) grade, 6-minute walk test (6MWT), Berg balance scale (BBS) score and modified Barthel index (MBI) score were evaluated before and after treatment in the two groups. The plantar pressure was measured by gait function evaluation system. RESULTS Compared before treatment, the Brunnstrom stage in the two groups was improved after treatment (P<0.01); the MAS grade in the observation group was improved after treatment (P<0.01); the Brunnstrom stage and MAS grade in the observation group were superior to those in the control group (P<0.01, P<0.05). After treatment, the 6MWT, BBS and MBI scores in the two groups were increased (P<0.05), and those in the observation group were higher than those in the control group (P<0.05). After treatment, the touchdown area of health-side hind foot, affected-side front-hind foot and bilateral full foot in the observation group was increased (P<0.05), and the touchdown area of affected-side front-hind foot and full foot in the observation group was larger than that in the control group (P<0.05). The weight-bearing ratio of health-side forefoot and full foot in the observation group was decreased after treatment (P<0.05), and the weight-bearing ratio of affected-side forefoot, hind foot and full foot was increased after treatment (P<0.05). The weight-bearing ratio of health-side forefoot and full foot in the observation group was lower than that in the control group (P<0.05), and the weight-bearing ratio of health-side hind foot, affected-side forefoot and affected-side full foot in the observation group was higher than that in the control group (P<0.05). CONCLUSION The scalp acupuncture combined with lower-limb intelligent feedback training could reduce the muscle tension of lower limbs, promote the separation movement mode of lower limbs, improve the plantar pressure distribution, and improve the balance ability and walking ability in stroke patients, and the curative effect is better than lower-limb intelligent feedback training alone.

Abstract
OBJECTIVE To observe the effect of acupuncture plus hyperbaric oxygen (HBO) on cerebral blood perfusion in patients with delayed encephalopathy after carbon monoxide poisoning (DEACMP). METHODS Twenty-eight patients with DEACMP were randomly divided into acupuncture group (n=14 cases) and control group (n=14 cases). Patients of the acupuncture group were treated by using "Xingnao Kaiqiao" needling technique (specific set of acupuncture points as Yintang [EX-HN3], Shangxing [GV23], Baihui [GV20], Sishenchong [EX-HN1], Fengchi [GB20], Taichong [LR3], etc., and strong stimulation) combined with HBO in an air pressurized tank, and those of the control group treated by simple HBO. The treatment was conducted once a day, 5 days a week for 6 weeks. All the patients underwent head routine magnetic resonance imaging (MRI) and intravoxel incoherent motion imaging(IVIM) scan before and after the treatment. The values of pseudo-diffusion coefficient D (D*) and perfusion fraction (f) of the bilateral semi-oval centers were measured by using MITK software package to calculate the ave-rage fD* value (f×D*). The Barthel index (BI) score was used to assess the patients' daily living ability, and the correlation between parameter values was evaluated by Pearson method. RESULTS After the treatment, the values of f, fD* and BI scores were significantly increased in both acupuncture group and control groups (P<0.05). The values of the 3 indexes were significantly higher in the acupuncture group than those in the control group (P<0.05). The values of f and fD* were positively correlated with BI score (P<0.05), with the correlation coefficients being 0.822, 0.636 and 0.601, respectively between the fD* and f, BI and f, and BI and fD*. CONCLUSION Acupuncture combined with HBO can significantly improve the low-perfusion of bilate-ral semi-oval center and daily living ability in patients with DEACMP, being significantly superior to simple HBO therapy in the curative effect.

Abstract
In this work, green-emission carbon dots (CDs) were prepared for detecting mercury ions (Hg(II)) and iodine ions via a facile hydrothermal method using ethylenediamine and methyl red as nitrogen and carbon sources, respectively, without any other complex reagents. The bacteriostasis experiment showed that the CDs were not toxic to the growth of four kinds of bacteria: Staphylococcus aureus (S. aureus), Bacillus subtilis (B. subtilis), Escherichia coli (E. coli), Pseudomonas aeruginosa (P. aeruginosa), which indicated that the CDs had good security and could be used for analysis and detection. The CDs exhibited excitation-independent emission, the fluorescence of which could be quenched by Hg(II), and could be recovered by iodine ions. An approach was established to detect Hg(II) based on the fluorescence quenching of CDs by the synergistic action of a photo induced electron transfer (PET) mechanism, and iodine ions were detected based on the fluorescence recovery of CDs by a HgI₂ precipitate formation mechanism. The detection limits for Hg(II) and iodine reached 0.89 μM and 0.50 μM, respectively. Compared to most methods, the method mentioned in this paper has good selectivity, a wider linear range, a lower detection limit and higher security. The synthesized CDs could be probes for sensing Hg(II) and iodine ions.

Abstract
Objective: To understand the situation and influencing factors related to the promotion of HIV testing program among sex partners in newly diagnosed HIV positive MSM in Zhejiang province during 2015 to 2017. Methods: Newly diagnosed HIV positive MSM in Zhejiang province from 2015 to 2017 were collected and provided four rounds of testing services to their sexual partners so as to study the consequences. Chi-square test was conducted to compare the difference between groups while multivariate logistic regression was conducted to analyze the related influencing factors. Results: A total of 6 269 HIV positive MSM were provided with four rounds of testing services to their sexual partners. 1 925 HIV positive MSM (30.7%, 1 925/6 269) were successfully persuaded in mobilizing their sexual partners to participate in the HIV testing services. However, 4 344 HIV positive MSM (69.3%, 4 344/6 269) refused to do so. A total of 2 126 sexual partners received HIV testing and the HIV positive rates of those sexual partners appeared as 13.0% (277/2 126, 95%CI:11.6%-14.5%) and 78.7% (218/277, 95%CI: 73.8%-83.6%). Results from the multivariate logistic regression analysis indicated that factors as: HIV positive MSM that participated in the study in 2016 (compared with participated in the study in 2015, OR=1.581, 95%CI: 1.370-1.823), in 2017 (compared with participated in the study in 2015, OR=1.394, 95%CI: 1.208-1.608), living in the reporting city (compared with lived outside the reporting city, OR=1.518, 95%CI: 1.320-1.745), being married (compared with unmarried/divorced/widowed, OR=4.449, 95%CI: 3.837-5.160), having education level of junior high school or below (compared with education level of senior high school or above, OR=1.203, 95%CI: 1.058-1.367), numbers of homosexual partners >5, (compared with numbers of homosexual partner from past between 1-5, OR=1.236, 95%CI: 1.095-1.395), active detection (compared with passive detection, OR=1.340, 95%CI: 1.193-1.506) were more likely to relate to the successful persuasion on their sexual partners to receive the HIV testing. There was no statistical difference noticed between HIV-infected homosexual partners and their corresponding HIV positive MSM, in terms of socio-demographic situations. Conclusions: HIV positive MSM should promote their sexual partners to receive HIV testing. This seemed an important role in expanding the HIV testing in this population. However, the program needs to be further improved and included in daily work, focusing on those partners with similar social and demographic characteristics with those infected MSM.

Abstract
Objective: Using field epidemiological investigation and molecular analysis to construct the molecular transmission network of human immunodeficiency virus/acquired immunodeficiency syndrome cases (HIV/AIDS) newly diagnosed in Huzhou in 2017, Zhejiang Province. Methods: A total of 160 participants were obtained through a web-based system from Chinese Center for Disease Control and Prevention (CCDC) with the features of diagnosed in Huzhou in 2017 who also had been collected samples for the first follow-up. The basic information of demographic characteristics and risk factors was extracted from the website. RNA was extracted from plasma samples of untreated cases, followed by RT-PCR and nest-PCR for pol gene amplification, sequencing. Phylogenetic tree was constructed by MEGA software for HIV gene subtyping. TN93 model was used for calculating the distance between two sequences. Cytoscape software was used for drawing molecular transmission network. And then an epidemiological survey was conducted to cases in the primary cluster. Results: A total of 138 sequenced individuals (86.3%) were acquired from 160 individuals. Among which, 123 (89.1%) were male. The highest proportion of subtype was CRF07_BC (60, 43.5%), followed by CRF01_AE (46, 33.3%), and with four cases of Unique Recombinant Form (URF, CRF01_AE and CRF07_BC) and one case of URF (subtype B and C). A total of 18 molecular clusters included 56 individuals (40.6%) were found in the transmission network under the optimal genetic distance threshold (1.0%). The clustering proportion of CRF07_BC (66.1%, 37 cases) was higher than that of CRF01_AE. There were 9 clusters formed among CRF07_BC, including 37 cases (accounting for 61.7%, 37/60). The primary transmission cluster contained 11 cases, among which 9 cases were transmitted by homosexual sex. The first time of the cases to have homosexual behavior is range from 2010 to 2016, whose media number (P(25), P(75)) of partners was 6 (3.5, 8.5). Most of the cases come from Anhui Province and engaged in garment industry (5 cases), between which there were 8 cases used Blued software to seek for casual partners, 1 case seeking for casual partners in garden. Conclusion: With CRF07_BC and CRF01_AE predominantly circulating, HIV genetic diversity had been noticed in this area. The primary cluster was consisted of high proportion of locally new infections, and a specific population aggregation in limited place existed.

Abstract
Background Several reports indicated that the expression of Yes-associated protein (YAP) was associated with multi-drug resistance. Acidic microenvironment increased by the overexpression of vacuolar-ATPase (V-ATPase) was also observed in tumor growth and drug resistance. We hypothesize that proton pump inhibitors (PPIs), currently used in the anti-acid treatment of peptic disease, could inhibit the acidification of the tumor microenvironment and increase the sensitivity of tumor cells to cytotoxic agents. Thus, our objective is to explore the reversal of drug resistance by the inhibition of YAP through specific PPIs in the epithelial ovarian carcinoma (EOC) cells. . Results We found that V-ATPase D1 was a positive regulator of YAP. Sub-lethal doses of the proton pump inhibitor esomeprazole (EMSO) in combination with paclitaxel (PTX) increased the PTX sensitivity in PTX-resistant EOC cells, as compared to PTX single treatments by inhibiting YAP and reserving pH gradient created by the V-ATPase D1. Moreover, sub-lethal doses of EMSO combined with PTX decreased autophagy and improved caspases independent apoptosis of PTX-resistant EOC cells. Conclusions These results suggested that sub-lethal doses of esomeprazole reverse YAP-mediated PTX resistance through the inhibiting of both YAP expression and acidic tumor microenvironment created by the V-ATPase D1. Therefore, we think the use of PPIs represents a promising strategy to improve the effectiveness of anti-EOC.

Abstract
Lactoferrin (LF) is a soluble glycoprotein of the transferring family found in most biological fluids, functioning as a major first line defense molecule against infection in mammals. It also shows certain anti-tumor activity, but its clinical application in tumor therapy is limited because high dosage is required. In this study, we demonstrate that M860, a monoclonal antibody against human LF (hLF), could significantly increase the anti-tumor potential of low dosage hLF by forming LF-containing immune complex (IC). Human monocytes primed with LF-IC, but not hLF or M860 alone, or control ICs, showed strong tumoricidal activity on leukemia cell lines Jurkat and Raji through induction of secreted Granzyme B (GzB). LF-IC is able to colligate membrane-bound CD14 (a TLR4 co-receptor) and FcγRIIa (a low affinity activating Fcγ receptor) on the surface of human monocytes, thereby triggering the Syk-PI3K-AKT-mTOR pathway leading to GzB production. Our work identifies a novel pathway for LF-mediated tumoricidal activity and may extend the clinical application of LF in tumor therapy.

Abstract
Objective: To identify the status and risky factors of anal sexual intention in casual sex behavior in Zhejiang province. Methods: Stratified cluster sampling was conducted among college students in 13 colleges in 11 cities between October to November, 2018. 482 students were enrolled who self-reported "heterosexuality "and" ever had casual sex behavior". A self-designed network questionnaire was complimented containing basic information, knowledge of HIV, sexual behavior. Chi-square test was used to compared the difference of anal sex intention between different characteristic. The multivariate logistic regression methods was used to analyze the influence factors. Results: Among 482 students, the age was (20±1.442) years old. And 87.3% (421) were male and 29.0% (140) were from other province. The rate of anal sex intention were 19.4% (94/482) in total, with the rates of 38.1% (24/63) and 14.4% (53/367) in students with sexual number more than 5 and less than 5 (P<0.001), separately. Compared with students searching casual sexual partner with non-internet access (17.0%, 16/201), students searching sexual partner with internet access had higher risk of anal sex practice (27.8%, 78/281) (P<0.001). The rate of anal sex practice among students reporting "ever had casual sex after drinking "and" never had casual sex after drinking" were 30.5% (64/210) and 9.4% (25/266) (P<0.001). The multivariate logistic regression results revealed that compared with students searching casual sexual partner with non-internet access and reporting "never had casual sex after drinking", subjects searching sexual partner with internet access(OR (95%CI)=2.65 (1.34-5.23)) and "ever had casual sex after drinking" OR (95%CI)=3.02 (1.65-5.33) were more likely had higher risk of anal sex practice. Conclusion: Heterosexual college students in Zhejiang Province tend to have anal intercourse with causal sexual partners. Searching for causal sexual partners on internet or mobile phone dating software and having temporary sexual behavior after drinking were correlated factors.

Abstract
OBJECTIVE To explore the specificity of the relevant points along the governor vessel in chronic gastritis through the synchronous observation of the tenderness reaction and tenderness threshold on the back along the governor vessel in the volunteers with chronic gastritis and make the comparison with healthy volunteers. METHODS A chronic gastritis group and a healthy volunteer group were prepared, 30 cases in each one. Using synchronous comparison, the tenderness reaction at the point inferior to each of the spinous processes from T1 to L3 along the governor vessel was observed. The mechanical pressure pain threshold was determined. RESULTS Regarding the tenderness reaction at the point inferior to each spinous process on the back along the governor vessel, the occurrence rate was different significantly between the chronic gastritis group and the healthy volunteer group (P<0.01). The tenderness threshold at the point inferior to each spinous process from T1 to L3 along the governor vessel in the chronic gastritis group was lower than the healthy volunteer group, the tenderness thresholds from T4 to T9 and T12 were different significantly between the two groups (P<0.01, P<0.05). The tenderness reaction at the point inferior to each spinous process on the back along the governor vessel presented the significant negative correlation with the tenderness threshold in the chronic gastritis group (P<0.01), and the correlation was not displayed in the healthy volunteer group (P>0.05). CONCLUSION The point inferior to the spoinous process of T4 on the governor vessel, Shendao (GV 11, T5) and Lingtai (GV 10, T6) are the points with the high specificity in chronic gastritis, which provides the reference to clinical treatment with acupuncture and moxibustion. The occurrence rate of high tenderness reaction and the low tenderness threshold may be the important manifestation of the point specificity on the back along the governor vessel in chronic gastritis.

Abstract
Objective: To understand the epidemiological characteristics of one large HIV molecular transmission cluster in Jiaxing city, Zhejiang province, 2017 in order to select those people under high-risk and providing basis for programs on prevention. Methods: During 2017, newly diagnosed HIV/AIDS cases in this city were recruited. Plasma samples were collected from subjects, followed by RNA extraction, RT-PCR and nest-PCR for pol gene amplification, before being sequenced and aligned. Mega 6.0 software was used to construct phylogenetic tree, and Cytoscape 3.6.0 software was used to identify HIV molecular transmission clusters. Cases within the large transmission clusters were investigated, using a field-epidemiology-questionnaire. Data related to socio-demographics and previous sexual behaviors were collected and EpiData 3.0 and SPSS 20.0 software were used. Results: In the large transmission cluster with subtype identified as CRF07_BC, in Jiaxing, 2017, 26 cases of the total 30 cases were investigated. A total of 80.8% (21/26) could be identified as newly infected within the last two years and 30.8%(8/26) could be identified as newly infected within the last one year, including 22 cases infected locally. Among several infected cases who were at age 45 years or older, they admitted that they had experienced unprotected sexual contacts in local city for long time and having had more than 10 disclosed sexual contacts within the last two years at the local venues. Conclusions: This molecular cluster had been formed and scaled up quickly in recent two years, it has played an important role in promoting and scaling up the HIV transmission. Three cases identificed as high risk played an importantrde role in scaling up this cluster.

Abstract
OBJECTIVE To explore the effect of electroacupuncture (EA) on learning-memory ability and its correlation with miR-664-3p levels in the hippocampus in cerebral ischemia-reperfusion injury (CI/RI) rats. METHODS A total of 27 male SD rats were randomly divided into sham operation, CI/RI model and EA groups (n=9 in each group). The CI/RI model was established by occlusion of the middle cerebral artery (MACO) according to the modified Longa methods. EA was applied to "Baihui" (GV20) and "Shenting" (GV24) for 20 min, once a day for 7 days. The Morris water maze tests (place navigation tasks and spatial probe trials) were used to evaluate the rats' learning-memory ability. After EA intervention, the hippocampal tissue was collected to measure the mRNA and miRNA expression profiles by using high-throughput next generation sequencing. Bioinformatics analyses including Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses were performed to screen the most abundant differentially-expressed miRNAs and mRNAs, particularly the target genes of miR-664-3p. Their biological functional categories including the key biochemical metabolic pathways and signaling pathways involved in CI and EA effect in the left hippocampus tissue were analyzed. RESULTS The average escape latency of place navigation tests was significantly longer in the CI/RI model group than in the sham operation group (P<0.01), and obviously shorter in the EA group than in the model group (P<0.01); and the times of escape-platform quadrant crossing of the spatial probe trials were considerably fewer in the CI/RI model group than in the sham operation group (P<0.05), and markedly more in the CI/RI EA group than in the model group (P<0.05). Combined analysis of miRNA and mRNA showed that the differentially-expressed target genes of miR-664-3p were significantly up-regulated after CI/RI relevant to the sham operation rats (P<0.05) and notably down-regulated in the EA group relevant to the CI/RI model group (P<0.05). The GO analysis displayed that the target genes of miR-664-3p were significantly enriched in the category of cell transportation activity, ion binding,and transmembrane transporter activity, the production of precursor metabolites and energy, transportation, signal transduction,localization, etc. KEGG analysis showed that the target genes of miR-664-3p in this study were mainly enriched in the thyroid hormone pathway, Hippo signaling pathway, MAPK signal transduction pathway,cAMP signaling pathway, neurotrophic factor signal transduction pathway, etc. CONCLUSION EA of GV20 and GV24 can improve the learning-memory ability of CI/RI rats, which is closely related to its effect in down-regulating the levels of hippocampal target genes of miR-664-3p involving cellular transmembrane transportation,cell to environment interaction,cell-cell communication, etc.

Abstract
Acupuncture is widely used in the treatment of ischemic diseases of the central nervous system in different clinical stages and has achieved a good clinical effect. The current research showed that acupuncture can improve cerebral blood flow perfusion via increasing blood flow volume, blood flow velocity, the levels of vasomotor substances and reduction of blood viscosity and erythrocyte aggregation index. In recent years, many studies focused on the pathophysiological mechanism of acupuncture in improving cerebral ischemia via triggering the cholinergic vasodilatation, up-regulation of expression of vascular-related proteins and genes,attenuation of inflammatory reaction, etc. Currently, the methods for evaluating the effect of acupuncture are mostly noninvasive functional magnetic resonance imaging in healthy subjects. Future studies should include united selection of acupoints and acupuncture needle manipulations, more reasonable combination of different acupoints, united outcome evaluative standards, better repeatability, employment of big data, etc.

Abstract
The list of late complications after calcaneal fracture that can be treated through arthroscopic and/or endoscopic approach continues to expand. The late complications of calcaneal fractures can be classified into 3 groups: (1) those causing focal hindfoot or ankle pain, (2) those causing functional deficit, and (3) those present with diffuse and poorly localized pain. Many group 1 and some group 2 complications can be managed arthroscopically and/or endoscopically. There are usually multiple coexisting sources of the pain. Careful evaluation and analysis of a problem and detailed surgical planning with combination of arthroscopic/endoscopic and open procedures are key to success.

Abstract
Objective: To assess the prevalence of HIV infection and related factors in men who have sex with men (MSM) living for ≤5 years in Wenzhou of Zhejiang province. Methods: MSM who were aged ≥16 years, had lived in Wenzhou for ≥3 months and had anal sex and/or oral sex with men in the last 12 months were recruited through respondent-driven sampling (RDS) from February to October in 2015. The MSM recruited completed a questionnaire for the information collection on socio-demographic characteristics, sexual behavior, awareness of HIV and related intervention, mental health status. Blood samples were collected from them for serological detection of HIV and syphilis antibodies. Software SPSS 18.0 was used to analyze HIV infection and related factors. Results: A total of 454 MSM were investigated, 108 of them (23.7%) were HIV positive. There were 267 MSM who lived in Wenzhou for ≤5 years, and 73 of them (27.3%) were HIV positive. Most of them were workers and commercial servants aged ≥25 years with personal monthly income <4 000 yuan and educational level of junior high school or below. According to multiple logistics regression analysis, age of 25-68 years old (OR=12.19, 95%CI: 2.29-65.02), heterosexual behavior in recent 6 months (OR=0.42, 95%CI: 0.18-0.96), believing it was possible to be infected with HIV (OR=0.06, 95%CI: 0.01-0.95), believing it was impossible to be infected with HIV (OR=0.03, 95%CI: 0.01-0.35) and syphilis status (OR=3.32, 95%CI: 1.05-10.52) were the risk factors associated with HIV infection. Conclusion: Compared with MSM who lived in Wenzhou for >5 years, MSM who lived in Wenzhou for ≤5 years had higher HIV infection rate and higher prevalence of risk behavior. It is necessary to conduct targeted intervention among them.

Abstract
Objective: To understand the distribution of HIV-1 subtype diversity and its transmission characteristics in Zhejiang province. Methods: A total of 302 newly diagnosed HIV-1 positive patients were selected through stratified random sampling in Zhejiang in 2015. HIV-1 pol genes were sequenced successfully with reverse transcription PCR/nested PCR and phylogenetic analysis was conducted for 276 patients. Then a molecular epidemiologic study was performed combined with field epidemiological investigation. Results: Of 276 sequence samples analyzed, 122 CRF07_BC strains (44.2%), 103 CRF01_AE strains (37.3%), 17 CRF08_BC strains (6.1%), 9 B strains (3.2%), 6 CRF55_01B strains (2.2%), 5 C strains (1.8%), 1 CRF59_01B strain (0.4%), 1 CRF67_01B strain (0.4%), 1 A1 strain (0.4%), and 11 URFs strains (4.0%) were identified. Phylogenetic analysis revealed 16 clusters with only 15.1% (34/225) sequences involved among CRF07_BC and CRF01_AE strains. The clustered cases in MSM were higher than that in populations with other transmission routes. And clusters existed between the populations with different transmission routes. Conclusion: The major strains of HIV-1 in Zhejiang are CRF07_BC and CRF01_AE. The HIV subtypes showed more complexity in Zhejiang. It is necessary to strengthen the surveillance for HIV subtypes, carry out classified management and conduct effective prevention and control in the population at high risk.

Abstract
Objective: To understand the related factors on previous HIV testing behavior among MSM who visit gay bathroom in Hangzhou, Zhejiang province. Methods: Through time-location sampling (TLS) survey, men who had oral sex or anal sex with men in past 6 months were interviewed in the gay bathroom in Hangzhou from October 2015 to January 2016. Software SPSS 22.0 was used to analyze the HIV testing acceptance, sexual behaviors and condom usage of MSM during past 6 months, and χ(2) test and logistic regression model were used for univariate and multivariate analyses. Results: Our study planned to recruit 480 gay bathroom MSM, due to the unwilling or other factors, 465 MSM were surveyed. A total of 47.3% (220/465) gay bathroom MSM received HIV testing during past 6 months. Multivariate analysis indicated that being married (OR=0.35, 95%CI: 0.18-0.69), peer education (OR=4.31, 95%CI: 1.32-14.09), homosexual behavior during past 6 months (OR=1.85, 95%CI: 1.08-3.14), extramarital heterosexual behavior during past 6 months (OR=4.12, 95%CI: 2.45-6.91) might be positive factors related with HIV testing acceptation in MSM. Conclusion: Being married, homosexual behavior during past 6 months, extramarital heterosexual behavior, partner education might be the positive factors related with acceptance of HIV testing among gay bathroom MSM. Therefore, peer education needs to be strengthened. HIV testing after high risk sexual behavior needs to be promoted in MSM.

Abstract
Objective: To investigate the effect and mechanism of the antibacterial peptide cathelicidin secreted by tumor associated macrophages on the growth of colorectal cancer in mice. Methods: Azoxymethane (AOM)/ dextran sodium sulfate (DSS) method was used to establish a mouse model of colitis associated colon cancer. To induce tumor formation, cathelicidin antibody, IgG antibody (positive control) or PBS (negative control) was respectively injected into mice once every 3 days and lasted one month. Then the pictures of mice colon were taken, and the numbers of tumor were counted and evaluated. Expressions of cathelicidin in tumor associated macrophages isolated from tumor and adjacent normal tissues of mice were examined by quantitative RT-PCR (qRT-PCR) and Western blot. Expressions of the tumor proliferating antigen Ki-67, macrophage marker CD68 and cathelicidin in tumor and non-tumor tissues were determined by immunohistochemistry analysis. Apoptosis of cells from tumor tissues was analyzed by using TdT-mediated dUTP nick-end labeling (TUNEL). Results: In colon tumor tissues, cathlicidin strongly expressed in inflammatory cells (macrophages), but weakly expressed in tumor cells. The tumor number and size in mice injected with cathelicidin neutralizing antibody were 4.50±1.18 and (1.74±0.18) mm, respectively, significantly lower than 13.88±1.98 and (3.74±0.38) mm of mice injected with PBS (t=4.07, t=4.72; P< 0.01) and 15.25±1.82 and (3.40±0.36) mm of mice injected with IgG antibody (t=4.96, t=4.08; P<0.01). The Ki-67 positive rate of cells in tumor tissues of mice injected with cathelicidin neutralizing antibody was (28.20±3.44) %, significantly lower than (68.20±3.51) % of mice injected with PBS (t=8.135, P<0.01) and (69.20±3.41) % of mice injected with IgG antibody (t=8.461, P<0.01). Immunohistochemistry analyses showed that the expression of CD68 in tumor tissues of mice injected with cathelicidin antibody was significantly lower than that of mice injected with IgG antibody or PBS. TUNEL result showed that treatment with cathelicidin neutralizing antibody had negligible effect on the apoptosis of tumor cells. Conclusions: Cathelicidin secreted by tumor associated macrophages can promote the growth of colorectal cancer in mice, and neutralizing cathelicidin activity can inhibit the growth and proliferation of colorectal cancer. Cathelicidin mediated promotion of colon cancer proliferation may mainly be exerted by recruiting inflammatory cells such as macrophages into the tumor microenvironment.

Abstract
Objective: To understand the characteristics of distribution on HIV-1 subtypes and the transmission clusters in Yiwu in Zhejiang province. Methods: A cross-sectional study of molecular epidemiology was carried out on newly reported HIV/AIDS cases in Yiwu. RNA was extracted from 168 plasma samples, followed by RT-PCR and nest-PCR for pol gene amplification, sequencing, phylogenetic tree construction used for analyzing the subtypes and transmission clusters. Mutations on drug resistance was analyzed by CPR 6.0 online tool. Results: Subjects were mainly males (86.3%, 145/168), with average age as (39.1±13.4) years old and most of them were migrants (66.7%, 112/168). The major routes of transmission included homosexual (51.2%, 86/168) and heterosexual (48.8%, 82/168) contacts. The rate of success for sequence acquisition was 89.9% (151/168). The dominant subtypes showed as CRF01_AE (74, 49.0%) and CRF07_BC (64, 42.4%), followed by CRF08_BC (5, 3.3%), CRF55_01B (3, 2.0%), each case of subtype B, CRF45_cpx, CRF59_01B, CRF85_BC and URF (B/C). CRF45_cpx and CRF85_BC were discovered the first time in Zhejiang province. Twenty-six transmission clusters involving 65 cases were found, with the total clustered rate as 43.0% (65/151), in which the CRF01_AE clustered rate appeared as 54.1% (40/74), higher than that of CRF07_BC (21/64, 32.8%). The average size of cluster was 2.5 cases/cluster, with average size of cluster in CRF01_AE patients infected through heterosexual transmission as the largest (3.5 cases/cluster). The prevalence of transmitted drug resistance was 4.6% (7/151). Seven cases with surveillance drug resistant mutations (SDRM) were found, including 5 cases of M46L (3.3%), and one case of F77L or Y181C. Conclusion: HIV genetic diversity and a variety of transmission clusters had been noticed in this study area (Yiwu). Programs on monitoring the subtypes and transmission clusters should be continued and strengthened.

Abstract
Distraction osteogenesis (DO), one of effective therapies for bone regeneration, has been received more attention in recent years. However, the underlying mechanism remains elusive. Recently, microRNAs (miRNAs) have been reported to play important roles in regulating osteogenesis and bone formation. We therefore provided the hypothesis that miRNAs could involve in the DO-mediated bone regeneration. After successfully established the DO model of rats, a miRNA microarray was performed to find the differently expressed miRNAs in DO and control groups in this study. As one of the most downregulated miRNAs, miR-144-3p was found to be decreased during osteogenic differentiation in mesenchymal stem cells of rats (rBMSCs) and DO model. And miR-144-3p overexpression suppressed the osteogenesis while its inhibitor promoted osteogenesis. Furthermore, Connexin-43, an essential regulator for osteogenesis, was validated to be a novel target for miR-144-3p. Finally, miR-144-3p inhibitor modified MSCs promoted mineralization of distracted bone in rat DO model. In conclusion, miR-144-3p was found to regulate osteogenesis and inhibition of miR-144-3p resulted in acceleration of mineralization of DO, which not only give clues to understanding the mechanism of DO but also provide a potential therapeutic target in clinical practice.
