Type 2 diabetes mellitus （T2DM） and hypertension are common and frequent chronic non-communicable diseases， which often coexist in clinical practice， resulting in a large number of cardiovascular events and deaths， and their case fatality rate far exceeds that of other factors such as dyslipidemia and obesity. Based on the diagnostic standards， guidelines， and animal model evaluation methods of T2DM with hypertension at home and abroad， this study summarized， evaluated， and analyzed the characteristics of the existing animal models of T2DM with hypertension based on the clinical symptoms in traditional Chinese and Western medicine. The animal models showing high fitting degrees with the clinical symptoms in Western medicine are mainly established by injection of streptozocin （STZ） in SHR rats in the surgical induction and chemical induction methods and feeding a high-fat and high-salt diet combined with STZ injection in SD rats in the dietary induction methods. The models showcasing high fitting degrees with the clinical symptoms in traditional Chinese medicine （TCM） are mainly established by the surgical induction method. Considering the fitting degrees and the advantages and disadvantages， the ideal modeling method for T2DM with hypertension is the two-kidney， one clip （2K1C） method （a surgical induction method） combined with feeding a high-fat and high-sugar diet and STZ injection. However， the available models lack the characteristics of TCM and the evaluation indicators have poor specificity. This study found that there are few animal models of T2DM with hypertension considering the characteristics of both disease and syndrome， which may be related to the identification and attribution of TCM syndromes in animal macroscopic information. In view of this problem， it is suggested that the evaluation criteria should be established and improved for the animal models combining disease and syndrome， which can help to evaluate the fitting degree of the pathological characteristics of different syndromes in the animal models of T2DM with hypertension. In this way， ideal animal models of T2DM with hypertension can be established to simulate the disease occurrence and development in the human body. The animal models are expected to provide an ideal approach for the further research on the pathogenesis of T2DM and its prevention and treatment with TCM， which is of great significance for the treatment and prevention of T2DM with hypertension and the prognosis of its complications. At the same time， breakthroughs in the basic syndrome models of comorbidities are expected to lay a foundation for the leapfrog development of TCM research.

The rupture of carotid vulnerable plaques is the core pathological basis for major cardiovascular and cerebrovascular events. However， the insufficient alignment between existing animal models and the clinical disease and syndrome characteristics of traditional Chinese and western medicine has limited research progress. In this study， biomedical databases in China and abroad were systematically searched， and the modeling mechanisms and evaluation systems of carotid vulnerable plaque animal models were systematically assessed based on diagnostic criteria of both traditional Chinese and western medicine. Analysis of the clinical correspondence indicated that existing animal models can be categorized into four types： simple high-fat diet， surgical induction combined with high-fat feeding， genetic engineering combined with high-fat feeding， and drug induction combined with high-fat feeding. Among these， the compound strategy of surgical induction combined with high-fat feeding has become the current mainstream approach， showing good concordance with western medicine. The study found that the double balloon injury rabbit model and the ApoE^-/- mouse carotid artery tandem constriction combined with high-fat feeding model demonstrated a high degree of clinical correspondence with both traditional Chinese and western medicine in terms of vulnerable plaque imaging and pathological features. Nevertheless， existing models still face significant technical limitations in faithfully simulating plaque pathology and in translating findings to clinical applications. To address these challenges， integrating complex comorbidity mechanism construction， multimodal dynamic mechanism monitoring， and collaborative evaluation systems of traditional Chinese and western medicine could enable the development of highly concordant carotid vulnerable plaque disease-syndrome combination animal models. Such models would provide a reproducible experimental platform for targeted drug development to regulate plaque stability and for individualized precision treatment， as well as a theoretical basis for innovation in clinical diagnostic and therapeutic strategies.

This study investigated the primary pathogenesis and syndrome evolution of different heart failure with preserved ejection fraction(HFpEF)stages based on the classical and clinical experience of traditional Chinese medicine(TCM),combined with the clinical characteristics of pre-heart failure,symptomatic heart failure,and advanced heart failure.This study summarizes and refines the three core syndrome factors:water,deficiency and blood stasis.Water-fluid retention was observed throughout these three stages,from the beginning to the end.With the advancement of the disease,the heart yang changes from stagnation to deficiency,water-fluid retention gradually increases,blood stasis becomes increasingly prominent,and the disease location develops dynamically from the upper to the middle and lower jiao.This study proposes three methods of treating HFpEF.The main pathogenesis of pre-heart failure is lung qi dysfunction-induced water retention,which can be treated by dispersing lung qi and transforming water retention using Fuling Xingren Gancao Decoction.The primary pathogenesis of symptomatic heart failure is yang and qi deficiency-induced water retention,which can be treated with tonifying yang,supplementing qi,and transforming water retention using Shengxian Decoction combined with Linggui Zhugan Decoction.The primary pathogenesis of advanced heart failure is yang deficiency with blood stasis and water retention affecting the heart,which can be treated with tonifying yang,circulating blood,and expelling water retention using Zhenwu Tingli Decoction.Chinese medicine can be flexibly added or subtracted according to the patients'concurrent patterns.However,the daily care of patients should be considered.This study explores the staging treatment of HFpEF from water,deficiency and blood stasis to provide a TCM clinical reference for treating HFpEF.

ObjectiveTo understand the experience， knowledge and attitudes of e-cigarette users in Shanghai， and to provide evidence for the development of intervention programs for e-cigarette use. MethodsThe Respondent-Driven Sampling （RDS） method was used to recruit 40 e-cigarette users for qualitative interviews from November 2020 to February 2021. NVivo （11.0） software was used to code interview records， and the thematic pattern and relationship analysis were conducted. ResultsIn terms of the reasons and user experience of e-cigarette use， most respondents used e-cigarettes for the first time after recommendation of friends； The reasons for the current use of e-cigarettes focus on the subjective feelings generated by the use of e-cigarettes （easy to use， replacing traditional tobacco， and having many flavors）. Compared with traditional tobacco use， respondents said e-cigarettes tasted good and had no physical impact （they could be used all the time without making them uncomfortable）. In terms of the awareness of e-cigarette use related knowledge， the respondents' opinions on whether e-cigarettes caused health risks were mostly based on their own experience of using them， and they said it was difficult to identify real information online. As for whether they were interested in relevant knowledge， most respondents said they wanted to learn about the professional knowledge related to e-cigarettes. Regarding the attitude related to the use of e-cigarettes， most respondents believed that e-cigarettes are addictive， e-cigarettes are not a safe alternative to traditional tobacco， ande-cigarettes couldn't help them quit smoking. Three out of ten respondents said they supported including e-cigarettes in the Regulation on Smoking Control in Public. ConclusionThere are certain characteristics of e-cigarette users' feelings， related knowledge and attitude towards e-cigarette use that should be targeted to carry out publicity， education and intervention.

OBJECTIVE To investigate whether electroacupuncture(EA)ameliorates abnormal trigeminal neuralgia(TN)orofacial pain and anxiety-like behavior by altering synaptic plasticity in the hippocampus CA1.METHODS A mouse infraorbital nerve transection model(pT-ION)of neuropathic pain was established,and EA or sham EA was used to treat ipsilateral acu-puncture points(GV20-Baihui and ST7-Xia-guan).Golgi-Cox staining and transmission elec-tron microscopy(TEM)were administrated to observe the changes of synaptic plasticity in the hippocampus CA1.RESULTS Stable and per-sistent orofacial allodynia and anxiety-like behav-iors induced by pT-ION were related to changes in hippocampal synaptic plasticity.Golgi stain-ings showed a decrease in the density of dendritic spines,especially mushroom-type dendritic spines,in hippocampal CA1 neurons of pT-ION mice.TEM results showed that the density of synapses,membrane thickness of the postsynap-tic density,and length of the synaptic active zone were decreased,whereas the width of the synap-tic cleft was increased in pTION mice.EA attenu-ated pT-ION-induced orofacial allodynia and anx-iety-like behaviors and effectively reversed the abnormal changes in dendritic spines and syn-apse of the hippocampal CA1 region.CONCLU-SION EA modulates synaptic plasticity of hippo-campal CA1 neurons,and reduces abnormal oro-facial pain and anxiety-like behavior,providing evidence for a TN treatment strategy.

Objective To explore the effects of transcutaneous electrical acupoint stimulation (TEAS) on upper limbs function in chronic stroke patients. Methods From March, 2016 to May, 2018, 53 patients were randomly divided into control group (n = 27) and research group (n = 26). All the patients received conventional rehabilitation, and the research group received additional intervention of TEAS, for six weeks. They were assessed with Manual Muscle Test (MMT) on upper limbs, modified Ashworth Scale (MAS), Fugl-Meyer Assessment-upper extremities (FMA-UE), Hand Motor Status Scale and modified Barthel Index (MBI) before, at the end of 6-week treatment and twelve weeks after treatment. Results There was no significant difference in all the scores between two groups at the end of 6-week treatment (t < 1.511, P > 0.05). The scores of MMT of wrist dorsal extension, FMA-UE and MBI were better in the research group than in the control group twelve weeks after end of treatment (t > 2.312, P < 0.05). Conclusion TEAS may promote the recovery of hands and upper limbs function in chronic stroke patients.

OBJECTIVETo investigate the effects of PPARγ overexpression on steatosis in mouse primary hepatocytes.

METHODSPrimary hepatocytes isolated from C57BL/6J mice were infected with either Ad/LacZ or Ad/PPARγ for 48 h. Steatosis of the primary hepatocytes was checked by Oil Red O staining. The mRNA and protein expression of adipocyte-specific genes PPARγ, aP2 and CideA were analyzed by using RT Real-time PCR and Western Blot.

RESULTSPrimary hepatocytes were small and even. Hepatocyte nuclei were round with dispersed chromatin and prominent nucleoli. Accumulated lipid droplets were observed in Ad/PPARγ-infected hepatocytes, but in Ad/LacZ-infected hepatocytes. Moreover, compared with Ad/LacZ-infected hepatocytes, the mRNA expression of PPARγ, aP2, FGF21 and CideA in Ad/PPARγ-infected hepatocytes were significantly induced, the protein expression of PPARγ and its target aP2 strongly increased.

CONCLUSIONover expression of PPARγ induces adipogenic steatosis in mouse primary hepatocytes.

OBJECTIVETo explore the distribution of serum antibodies against human papillomavirus (HPV) 16/18 among women at high-risk for cervical cancer.

METHODSAll women when tested positive for anyone of the cervical cancer screening programs, from Xinmi county of Henan province in 2011, were recruited as the subjects of this study. Cervical exfoliated cells were collected, using cervical brush for HPV DNA testing, and 10 ml venous blood was drawn for HPV-16, 18 serum antibodies testing, by enzyme-linked immunosorbent assay.

RESULTSAmong the 952 women under study, 230 cases (24.2%)showed HPV DNA positive, with positivity rates of HPV16 and 18 L1 virus-like particle (VLP)antibodies as 23.2% and 6.5%, respectively. The overall positivity rate of any type of HPV16, 18 VLP antibodies was 26.8% . Geometric means of HPV16, 18 VLP antibody titers were 79.1 (Yangshengtang Unit,YU/ml) and 125.0(YU/ml). Positivity rate of HPV16 antibody was significantly associated with age, viral load of HPV DNA, and cervical lesion severity (P < 0.05). Seropositivity of HPV18 was also increasing with the increase of viral load (P < 0.01) with different cervical lesion significantly showing different titer of HPV18 antibody (P < 0.01). Based on the results of HPV DNA detection among the two years of study, women with HPV persistent infection showed significant higher positive rate of HPV16/18 antibodies than women who did not have HPV infection or emerging infection (P < 0.001). When comparing to those women without HPV infection, the ones with transient infection showed higher seropositivity rates on both HPV16 antibodies and titer of HPV16 antibody (P < 0.001).

CONCLUSIONSeroprevalence rates on HPV16 and 18 among the unvaccinated high-risk women in Henan were high. Prevalence of both HPV16 and 18 antibodies were correlated with age, viral load, cervical lesion and history of infection.Women with high viral load, high grade cervical lesion or history of infection would more likely to be seropositive.

OBJECTIVEInvestigating the distribution of anti-hepatitis E virus (HEV-IgG), anti-human papillomavirus (HPV L1-IgG) and risk factors among female residents in Xinmi County, to explore the influencing factors of HPV vaccine study using HEV vaccinated population as a control.

METHODSA screening study of cervical cancer in Xinmi County, Henan Province, was performed. The information of demographic characteristics and risk factors was collected using standard questionnaire. Nine ml blood was drawn from each woman for enzyme-linked immunosorbent assay to detect HEV-IgG and HPV L1-IgG antibody. Percentile, histogram and binary logistic regression model were used to describe the distribution of risk factors and their correlation to HPV and HEV infection.

RESULTSThe average age of the Xinmi female residents was 47.2 years, their positive rate of HPV L1 antibody was 26.8%, and that of HEV-IgG antibody was 31.0%, both of which were raised with age (P < 0.001). Single factor analysis showed that non-education, low-income and growing age were associated with HEV-IgG antibody positivity, and non-education, lowering ages of first sexual life and growing age were associated with HPV L1-IgG antibody positivity. Multivariable analysis showed that growing age, low-income and work as peasantry were independent risk factors for HEV-IgG antibody positivity, and lowering ages of first sexual life, non-education and growing age were independent risk factors for HPV L1-IgG antibody positivity.

CONCLUSIONSBoth the HEV-IgG and HPV L1-IgG antibodies positive rates increase with age. Age is the common risk factor of HEV-IgG and HPV L1-IgG antibodies in female residents in Xinmi County. The risk factors of HEV-IgG and HPV L1-IgG antibodies have no statistical association, neither cross reaction was found in the HEV-IgG and HPV L1-IgG detection.
