Objective:To evaluate the protective effect of Diclipterachinensis polysaccharide P2B on liver cell line L-02 injury in-duced by carbon tetrachloride ( CCl4 ) . Methods:The human liver L-02 cells were cultured, and the injury model was built by CCl4 . The L-02 cells were divided into the normal control group, the CCl4-damaged group, and the P2B sample groups (0. 125, 0. 250 and 0. 500 mg· ml-1 ). The contents of alanine aminotransferase ( ALT), aspartate aminotransferase ( AST), superoxide dismutase (SOD) and malondialdehyde (MDA) were determined by MTT assay. Results:Compared with the CCl4-damaged group, P2B could improve the activity of L-02 cells, and the activity of AST and ALT in the supernatant was significantly reduced, and the content of SOD in the cells was increased and that of MDA was decreased. Conclusion:P2B can significantly prevent L-02 cells from the damage induced by CCl4 in a dose-dependent manner, and the mechanism may be related with the anti-oxidative activity of P2B.

Objective To investigate the reasons of blood pressure not reached standard in community outpatients with hypertension.Methods During January 2001 to December 2006,2798 patients fitting the China hypertension guide standard providing prevention and curing were involved in this study.From them,1574 cases were treated repeatedly,and the blood pressure did not continuously reach the controlled standard.The reasons were analyzed by regular visiting and correspondence with patients.Results The reasons of blood pressure not reached controlled standard related with chiefly the following factors:patient had bad compliance,and not positively intervened the way of life,and not took medicine according to the doctor's advice;doctors were not familiar with the methods of preventing hypertension and the treatment was nonstandrad.Conclusion The reasons of blood pressure not reaching standard in community outpatients with hypertension mainly are that the patients have poor knowledge about hypertension and compliance,and the treatment is nonstandrad.

Objective To investigate the relationship between the genetic polymorphisms, which played roles in the pathogenesis of metabolic syndrome (MS), and susceptibility of non-alcoholic fatty liver disease (NAFLD) in Han people in Guangdong province. Methods The subjects were selected from an epidemiologie survey in Guangdong province. Fifty to 117 adult NAFLD patients, who met the criteria of Chinese guideline for diagnosis of NAFLD and had typically clinical, biochemical signs and abdominal ultrasonography, were recruited in the study. By using 1 : 1 matched method of nested case-control study, same numbers of people without NAFLD were included as controls. The genetic analyses was performed by using genomic DNA extracted from peripheral blood. Polymerase chain reaction (PCR)-restriction fragment length polymorphism (RFLP) was applied to detect the single nucleotide polymorphisms (SNPs) at 9 sites in 7 candidate genes. Results Most SNPs of the genes were related to the susceptibility of NAFLD. Some of them had positive relation (increasing the risk) such as tumor necrosis factor (TNF)-α-238, adiponectin-45, leptin-2548, peroxisome proliferator-activated receptors (PPAR) γ-161 and phosphatidylethanolamine N-methyltransferase (PEMT)-175. Some had negative relation (decreasing the risk) including adiponectin-276 and hepatic lipase-514. And some had no relation (TNF-α-380 and PPAR g coactivator-1α-482). Conclusion Most cytokines' SNPs of candidate genes discovered in MS patients are related to the susceptibility of NAFLD.

Objective To explore the difference in ocular biologically effective ultraviolet irradiance in two areas with different altitudes ,Xichang and Shaoxing,and provide a reference basis for ocular UV protection. Methods A self?designed rotating mannequin and dual?detector spectrome?ter were used to monitor the intensity of ocular exposure to UV irradiation under clear skies in Xichang and Shaoxing. Monitoring data were pro?cessed and analyzed with AvaSoft 7.4 USB2 software and OriginPro 8.0 software. Results The diurnal variations of ocular biologically effective ul?traviolet irradiance exhibited bimodal distribution in Xichang and Shaoxing. The maximum UVBEcorn,UVBEconj,and UVBElens of Xichang were about 1.7 times,2 times,and 1.8 times that of Shaoxing,respectively. Under the same solar elevation angle,the biologically effective ultraviolet irra?diance of the cornea,conjunctiva,and lens in Xichang were higher than those of Shaoxing. Conclusion The diurnal variations of ocular biologi?cally effective ultraviolet irradiance exhibit bimodal distribution in areas at two different altitudes. Under the same solar elevation angle ,the biologi?cally effective ultraviolet irradiance of the cornea,conjunctiva,and lens of Xichang are significantly higher than those of Shaoxing.

Tuberculosis(TB) caused by the Mycobacterium tuberculosis(Mtb) is a worldwide public health threat.Microbiota in body affects human health and is involved in human diseases, and its clinical importance is begi-nning to be understood.In this review, studies on the relationship between the establishment of Mtb infection and microbiota as well as the development and antibiotic treatment of Mtb infection were discussed.Studies have shown that: (1) microbiota influences the establishment of Mtb infection; (2) co-infection of Helicobacter pylori alters susceptibility to Mtb infection and progression of active TB; (3) microbiota influences the progression of TB by regulating the nutritio-nal, metabolic and immune status of the host; (4) susceptibility to reinfection increases in TB patients treated with antibiotics, possibly due to T-cell epitope depletion of common intestinal non-Mtb Mycobacterium, the effects of antibio-tics are long-term in patients; (5) the occurrence of childhood TB is age-related and many factors such as co-infection and vaccine inoculation increase risk.An in-depth study of the relationship between the microbiota and TB will provide a new perspective on the prevention of TB.

Objective To summarize the characteristic of muscle MRI of lower limbs in patients with GNE myopathy and to explore the correlation between the fatty degenerative score of muscle MRI and clinical phenotype.Methods This was a prospective study. Seventeen patients with genetically confirmed GNE myopathy,having lower limb muscle MRI test and completed clinical and laboratory data.The degree of fatty degeneration in 18 muscles of lower limbs in each patient was grading.According to the GM-W score, these patients were divided into two groups.GM-W score≤3 were divided into mild group(n=8)and GM-W score≥ 4 were divided into severe group(n=9). Kruskal-Wallis test was used to compare the fatty degenerative score in different muscles of the thigh and the calf level;Mann-Whitney U test was used to compare score of the same muscle between mild and severe group;Spearman rank correlation test was used to analysis the relationship between fatty degenerative score and the course of disease (year), GM-W score, creatinine kinase (IU/L), respectively.Results At the thigh level, the most severely involved muscle of GNE myopathy was semi-tendinosusand adductor, followed by semi-membranous, biceps femoris and gracilis. There was no statistically significant difference in the fatty degenerative score of the above-mentioned muscles (P=0.058). At the calf level, the most severely involved muscle was medial of soleus which score was 4.0(3.0, 4.0), followed by tibialis anterior,extensor digitorum longus and lateral of soleus. There was no significant difference of the above (P=0.259).The fatty degenerative score showed difference between the mild and severe group at sartorius and adductor(P<0.05).At the calf level,the fatty degenerative score in peroneus longus, medial of soleus, lateral of soleus, medial of gastrocnemius and lateral of gastrocnemius showed difference between groups(P<0.05).The total score of fatty degenerative of Lower limb muscles was positively correlated with GM-W score(r=0.730, P<0.05). There were positive correlations between the score of fatty degenerative of the sartorius,peroneal longus,lateral of soleus,medial of gastrocnemius, lateral of gastrocnemius and the GM-W scores( r=0.630,0.845,0.569,0.591,0.640, 0.659,P<0.05).The total score of fatty degenerative of Lower limb muscles was not correlated with the level of creatine kinase(P=0.582), course of disease(P=0.601) and age of onset(P=0.850). Conclusions GNE myopathy in the thigh level within the adductor muscle and posterior muscle involvement, calf level to the tibial anterior muscle early involvement. The total score of fatty degenerative of lower limb muscles is positively correlated with GM-W score,but not correlated with the level of creatine kinase,course of disease and age of onset.

This work investigates the effects of Guilingji (GLJ) on D-galactose-induced aging and changes in serum metabolites by UHPLC-Q exactive orbitrap-MS in rats. The rat model of aging by subcutaneous injection of D-galactose (300 mg·kg^-1) was used to analyze the effect of different concentrations of GLJ (37.5, 75, 150 mg·kg^-1) on an open field test in aging rats. Rat serum was collected after 8 weeks and subjected to LC-MS to analyze the anti-aging effect of GLJ. Animal experimentation was approved according to the Committee on the Ethics of Animal Experiments of Shanxi University (SXULL2014032). GLJ significantly improved the autonomous activity of rats. Compared with the control group, 23 metabolites in the treated group changed significantly, involving three main pathways. The group that was given GLJ had altered regulation of 4 serum metabolites in two pathways. Our results indicate that GLJ can delay aging behavior in rats; the mechanism of this anti-ageing effect remains to be determined.

Objective To put forward suggestions for improving the scheme of general practice for functional communities from the perspective of supply and demand,guide the efficient use of the resources of general practice by the communities,and incorporate the general practice of communities into hierarchical diagnosis and treatment management. Methods In July 2021,stratified random sampling was employed to conduct the questionnaire surveys of the young and middle-aged (demand side) and the general practitioners (supply side),respectively.SPSS 20.0 was used for data analysis. Results The two sides had the same cognition about the main reasons for not signing a contract with a family doctor,which were the lack of knowledge about general practitioners and the lack of face-to-face communication opportunities.They had the same response about the form of services,with high acceptance of medical services via WeChat,outpatient consultation,and the internet.There were differences in service content between the two sides.The top three demands of the young and middle-aged were appointment registration and referral in superior hospitals,medication guidance,and massage,acupuncture,and moxibustion.The top service self-rated by general practitioners was personalized guidance and report interpretation of physical examination,and the bottom was massage,acupuncture,and moxibustion. Conclusions The general practice varies between the demand and supply sides.General practitioners should be encouraged to enter and learn functional communities and provide personalized services,thus improving the general medical service in functional communities.
