Transcuataneous electrical nerve stimulation (TENS) analgesia as a non-drug method has received people's more and more attention recently. Considering problems of existing products, such as unstable performance and unsatisfied effectiveness, we developed a new analgesia therapy system for delivery based on bio-feedback TENS in our laboratory. We proposed a new idea for stimulation signal design, that is, we modulated a middle frequency signal by a traditional low frequency TENS wave in the new system. We designed different prescription waves for pain relief during a uterine contraction or massage between contractions. In the end, a bio-feedback TENS method was proposed, in which the waveforms of stimulation signals were selected and their parameters were modified automatically based on feedback from uterine pressure, etc. It was proved through quality tests and clinical trials that the system had good performance and satisfied analgesia effectiveness.

ObjectiveTo observe the influence of mitochondrial cytochrome c oxidase(COX) decrease on cholinergic and dopaminergic system in brain of model rats.MethodsRats were administrated with 1mg/kg/h or 2mg/kg/h subcutaneously via an Alzet minipump for 30 days. Choline-acetyl-transfertase(ChAT) and acetylcholinesterase(AChE) activity in hippocampus and cortex of rats were measured by radiochemical method and hydroxylamine colorimetry separately. The contents of Norepinephrine(NE), dopamine, 5-hydroxytryptamine(5-HT) and their metabolic products in striatum were measured by HPLC.ResultsChAT activity was significantly inhibited in hippocampus and cortex of model rats, however, the activity of AChE increased in hippocampus and was not affected at the cortex. Therefore, the ratio of ChAT/AChE decreased in model rats. The content of NE, dopamine, 5-HT and their metabolic products in striatum were not different among all groups.ConclusionsCOX deficiency can induce abnormality of ChAT and AChE activity in model rats. Dysfunction of neurotransmitter-acetylcholine would be account for learning-memory deficiency. Model rats indicated cholinergic system deficit without any dopaminergic system abnormality, so chronic infusion of sodium azide via minipump may specially serve as a tool for developing the experimental model of Alzheimer's disease.

Tau protein, a kind of microtubule-associated protein, plays an important role in the pathogenesis of Alzheimer's disease (AD) and other tauopathies, and has drawn more and more attention of scientific researchers. Appropriate animal models of mutated tau protein are important in the studies of the pathogenesis and drug therapy of tauopathies. So far, some transgenic animal models expressing human tau protein have been established, among which the transgenic animal model overexpressing P301L mutated form of tau protein has been widely used because of its obvious pathological changes. In this review, we will review the research progress in the pathological manifestations of the P301L tau transgenic animal model and its applications in pharmacological studies.

OBJECTIVETo explore the changes in HBsAg titer and HBV DNA load and their correlation in patients with chronic hepatitis B (CHB) and HBV-related liver cirrhosis (HBV-LC).
METHODSForty-six patients with mild to moderate CHB (CHB-LM), 24 patients with severe CHB (CHB-S), and 28 patients with HBV-LC at admission, and 51 patients with HBV-LC at 4.08 ± 3.06 months during antiviral treatment were tested for serum HBsAg titer and HBV DNA load using Abbott chemiluminescence and fluorescence quantitative PCR, respectively.
RESULTSThe serum HBsAg titer and HBV DNA load gradually decreased with increased disease severity (from CHB-LM, CHB-S to HBV-LC; χ(2)=12.537 and 8.381, respectively, P<0.05). HBsAg titer and HBV DNA load were significantly higher in CHB-LM and CHB-S groups than in HBV-LC group (P<0.05), but comparable between CHB-LM and CHB-S groups (Z=-0.649 and 0.032, respectively, P>0.05). Among HBeAg-positive patients, HBsAg titer and HBV DNA load tended to decrease with increased disease severity (from CHB-LM, CHB-S to HBV-LC; χ(2)=6.146, P=0.046 and χ(2)=1.017, P>0.05; respectively), and CHB-LM group had significantly higher HBsAg titer than HBV-LC group (Z=-2.247, P=0.025). Among the HBeAg-negative patients, serum HBsAg and HBV DNA load gradually declined with the disease severity (χ(2)=8.660 and 13.581, respectively, P<0.05), and were obviously higher in CHB-LM and CHB-S groups than in HBV-LC group (P<0.05). Positive correlations were found between serum HBsAg and HBV DNA levels in CHB-LM (r=0.389, P=0.009) and HBV-LC groups (r=0.431, P=0.022), but not in CHB-S group (r=0.348, P=0.104). After antiviral therapy, the serum HBsAg titer was slightly decreased (Z=-1.050, P=0.294) while HBV DNA load markedly reduced (Z=-5.415, P<0.001), showing no correlation between them (r=0.241, P=0.111) or between the measurements before and after treatment (r=0.257, P=0.085).
CONCLUSIONSerum HBsAg titer and HBV DNA load decreases progressively from CHB-LM to CHB-S and HBV-LC in both HBeAg- positive and -negative patients. The serum HBsAg titer is positively correlated with HBV DNA load, but their levels are not consistently parallel.

Objective:To investigate the relationship between inherited dysplasminogenemia and cerebral infarction (CI) by phenotype and gene mutation analysis of 2 inherited dysplasminogenemia pedigrees.Methods:Retrospective analysis was carried out on clinical data of 2 patients diagnosed with CI who were treated in the Department of Neurology, the First Affiliated Hospital of Wenzhou Medical University in January and March 2021, and peripheral venous blood samples were collected from proband 1 and his family members (8 subjects, 4 generations in total) and proband 2 and her family members (5 subjects of 3 generations in total), and their plasminogen (PLG) activity (PLG:A), protein C activity, protein S activity, antithrombin activity and the content of PLG antigen (PLG: Ag), fibrinogen, D-dimer and fibrinogen degradation products were measured for definite diagnosis. All 19 exons,5′ and 3′ untranslated regions of PLG were amplified with polymerase chain reaction, and the amplification products were analyzed by direct DNA sequencing. The results were compared with human PLG reference sequences published in the National Center for Biotechnology Information database using Chromas software to find the mutation sites, and confirmed by reverse sequencing.Results:Both of the 2 patients with confirmed CI had a young onset, and PLG: A was reduced to 21% in the proband 1 and to about 50% in 4 family members; PLG: A was reduced to about 50% in the proband 2 and 2 family members; PLG:Ag and the above tests were essentially normal in both probands and family members. Gene analysis showed that the proband 1 had the homozygous mutation of c.1858G>A in exon 15, the 4 family members of the proband 1, proband 2 and her 2 family members had the heterozygous mutation of c.1858G>A in exon 15, which resulted in a mutation of alanine at position 620 in PLG to threonine (p.Ala620Thr).Conclusions:The decrease of PLG:A was caused by the p.Ala620Thr missense mutation of PLG gene. Proband having CI may be related to the inhibition of fibrinolytic function in the organism due to the p.Ala620Thr missense mutation.

Objective:To evaluate the value of shear wave elastography (SWE) in skin assessment of Systemic sclerosis (SSc).Methods:A total of 58 SSc patients admitted to Peking University Third Hospital from May 2021 to October 2022 and 41 healthy volunteers were included in the study. Skin shear wave elastography (SWE) was performed at 17 sites defined in modified Rodnan skin score (mRSS) measurement, and shear wave velocity values were recorded to evaluate skin hardness. SPSS 22.0 software was used to analyze the skin hardness of SSc patients and healthy controls, and the correlation between skin hardness of SSc patients and clinical data was analyzed. A logistic regression model was constructed to evaluate the diagnostic efficacy of skin hardness at different sites of SSc patients, and to further select the most practical measurement site.Results:The SWE value of SSc patients was significantly higher than that of healthy control group ( P<0.05). There was a positive correlation between SWE and mRSS in the measurement of bilateral fingers, bilateral dorsal hands, bilateral forearms, fore-chest, abdomen, bilateral thighs, and bilateral dorsal feet. Skin stiffness measured by SWE was significantly correlated with SSc disease activity score (EScSG-DAI), ( r=0.71, P<0.001), disease injury score (SCTC-DI), (P=0.55, P=0.005) and functional score (HAQ-DI), ( r=0.46, P=0.003). Reducing the number of measurement sites to 12 (bilateral fingers, bilateral hands, bilateral forearms, bilateral upper arms, forehead, fore-chest, bilateral dorsum of feet) performs as well as all 17 measurement sites simultaneously in assessing disease activity. Conclusion:SWE is a good evaluation tool to reflect the skin lesions of SSc, which is of great value for the diagnosis and evaluation of the disease. We can further standardize the measurement sites and select the most appropriate evaluation strategy, so as to achieve better clinical application.
