Objective To study the activation of Janus protein tyrosine kinase (JAK)/signal transducer and activator of transcription 1 (STAT1) signaling pathway and its inhibitor-signal transducer and activator of transcription-1(SOCS-1) in patients with systemic lupus erythematosus. Methods A total of 45 patients with active systemic lupus erythematosus (SLE) and 30 healthy controls were randomly selected. Western blot was performed to measure the expression of Stat1 protein and phospho-Stat1 protein (an activated form of Stat1 protein) in the monocytes after stimulation with recombinant high mobility group box1 (rHMGB1) at various time points. Expression of Stat1 protein in the skin or lesional skin was also detected. Phasic expressions of SOCS-1 mRNA in the monocytes after rHMGB1 stimulation were detected by real-time reverse transcription-polymerase chain reaction. SOCS-1 gene expression in the skin or lesional skin was also detected. Results The expression level of Stat1 proteins in the monocytes from patients with SLE was higher than that from healthy controls (t=9.16,P＜0.01) and positively correlated with SLE disease activity index (SLEDAI) (r=0.59,P＜0.01). Expression of phospho-Stat1 in the monocytes from SLE patients was time-dependently upregulated after stimulation with rHMGB1 at various time points, while expression of SOCS-1 mRNA remained unchanged(all P＞0.05). Expressions of phospho-Stat1 protein and SOCS-1 mRNA in the monocytes from healthy controls were increased transiently after stimulation with rHMGB1(all P＜0.05). Both expressions of phospho-Stat1 protein and SOCS-1 gene in the lesional skin from patients with SLE were upregulated compared with those in normal skin from healthy controls (all P＜0.01). Conclusion There are hyperactivation of JAK-STAT1 signaling pathway and negative feedback down-regulation of SOCS-1 in patients with systemic lupus erythematosus. HMGB-1 may be partly involved in the pathogenesis of SLE by the abnormal mediating function of JAK-STAT1 signal transduction pathway.

Objective To explore MRI manifestations of incomplete healing of the uterine incision after abdominal delivery.Methods Nine patients with clinical suspected incomplete healing of the uterine incision after abdominal delivery underwent cavitas pelvis MRI scans with 3.0T MRI.Results According to the characteristics of the MRI images,healing conditions of the uterine incisions were divides into 2 groups.GroupⅠwas showed that the uterine incision healed well,the uterine junctional zone and myometrium were continuous,and the incision scar was linear low signal intensity on T2 WI (2 cases,22%).GroupⅡwas showed that the uterine incisions healed incompletely,the uterine junctional zone and myometrium were discontinuous,and the myometrium edema was in some cases with high signal intensity on T2 WI (7 cases,78%).Conclusion MRI could directly displays incomplete healing of the uterine incision after cesarean section,provide the basis for clinical diagnosis and treatment.

Objective: To observe the clinical efficacy of DZWJY-1 type electronic moxibustion apparatus and traditional moxibustion in treating knee osteoarthritis (KOA). Methods: A total of 76 eligible patients were randomized into an electronic moxibustion apparatus group and a traditional moxibustion group, with 38 cases in each group. The electronic moxibustion apparatus group was intervened by DZWJY-1 type electronic moxibustion apparatus, and the traditional moxibustion group received moxa stick moxibustion for treatment. Neixiyan (EX-LE 4), Dubi (ST 35), Xuehai (SP 10) and Liangqiu (ST 34) were selected for both groups and the treatment was conducted 3 times a week for a total of 12 times. The visual analog scale (VAS) and the Western Ontario and McMaster Universities osteoarthritis index (WOMAC) scores were observed before treatment and after 6 and 12 sessions of treatment, respectively. Results: There were 4 dropout cases in the traditional moxibustion group. Therefore, this trial had 72 valid cases, including 38 cases in the electronic moxibustion apparatus group and 34 cases in the traditional moxibustion group, the differences in the baseline data between the two groups were statistically insignificant (P>0.05). After 6 and 12 sessions of treatment, the VAS scores decreased significantly with the increase of treatment sessions in both groups (all P<0.01), and the betweengroup differences were statistically insignificant at the same time points (both P>0.05). The pain intensity was evaluated using the weighted value of VAS score. The markedly effective rate was 47.4％ and the total effective rate was 89.5％ in the electronic moxibustion apparatus group, versus 50.0％ and 94.1％ in the traditional moxibustion group, and the betweengroup differences were statistically insignificant (both P>0.05). After 6 and 12 sessions of treatment, the total score and the component scores including pain, stiffness and difficulty moving in the WOMAC decreased significantly with the increase of treatment sessions in both groups (all P<0.01), and the between-group differences were statistically insignificant (all P>0.05). Conclusion: Electronic moxibustion apparatus and traditional moxibustion both are effective in reducing joint pain and improving joint function in KOA patients, and they are equivalent comparing the clinical efficacy.

Abstract: Schistosomiasis, an important zoonotic parasitic disease, is one of the six major tropical diseases identified by WHO, and also one of the most important parasitic diseases for prevention and control in China. After more than 70 years of efforts, the prevention and control of schistosomiasis in China has made great achievements, and the current epidemic of schistosomiasis in China has entered an extremely low epidemic state, but the distribution base of the only intermediate host of schistosomiasis, Oncomelania hupensis, is still large. For now, the techniques used to monitor schistosomiasis have shortcomings such as time-consuming, laborious and low sensitivity, which cannot meet the current needs of China. Environmental DNA (eDNA) refers to DNA that can be extracted from environmental samples (such as soil, water or air) without isolating any target organisms, which is a complex mixture of genomic DNA and its degradation products from different organisms in the same environment. eDNA technology can reflect the community or species composition information in the ecosystem through DNA extraction and detection of environmental samples. Compared with traditional biological monitoring methods, eDNA technology has the advantages of high efficiency, high sensitivity and environmental friendliness. eDNA has been successfully used for the specific detection of Schistosoma mansoni, Schistosoma haematobium and Schistosoma japonicum. This paper reviews the current detection methods of eDNA, the application and technical limitations of eDNA technology in schistosomiasis monitoring, aiming to provide scientific reference for research in the field of schistosomiasis surveillance.

Objective: To analyze the relationship between inflammatory factors and relevant risk factors in patients of essential hypertension (EH) combining acute coronary syndrome (ACS) with its clinical significance. Methods: Our research included 3 groups: EH group, n=79 patients with standard criteria, EH+ACS group, n=85 and Control group, n=48 normal subjects. Blood levels of lipoprotein-associated phospholipase A2 (Lp-PLA2), tryptase (TPS) and relevant clinical, biochemical parameters were measured; risk factors for cardiovascular disease were examined and the relationship between above parameters, risk factors and ACS occurrence in EH patients was studied by Logistic regression analysis. Results: The OR values were all greater than 1 in fibrinogen (Fbg), high-sensitivity C-reactive protein (hs-CRP), TPS, atherosclerotic plaque, Lp-PLA2 and EH grading. Fbg was the most significant independent risk factor (OR=22.242, 95% CI 6.458-76.609, P<0.0001), the standardized partial regression coefficient b'as absolute value (b') was 1.079 which was the highestone in above 6 variables with the strongest impact for ACS occurrence in EH patients. Conclusion: Fbg, hs-CRP, TPS, atherosclerotic plaque and EH grading were the independent risk factors for ACS occurrence in EH patients; Fbg was the highest risk factor for ACS occurrence with the strongest impact, which provided a new direction for ACS prevention and treatment.
