Objective To confirm the optimal tissue sampling location of current injury combined with the histopathological observation in specific parts of electrocution based on previous animal experiments. Methods Twenty-three human cases from the autopsy through the hand-to-foot circuit pathway were analyzed. Additional ten autopsy patients who died from traffic accidents and sudden cardiac attacks were used as the control group. All cases were extracted the soft tissues from the upper anterior wrist and medial malleolus to further observe and analysis the L/S axis ratio of the nuclei of the skeletal muscle cells (SkMCs) and artery smooth muscle cells (ASMCs). Results The age of the 23 eligible electrical deaths ranged from 19 to 59 years, including 19 cases were male and 4 cases were female. 3 cases were high-voltage 20 cases were low voltage. The occurrence rate of electric marks averaged 31.18% in all cases. The incidence of the classical arborizing pattern of fine branching was 36.4%, appearing on the pleura in 5 cases (22.7%). The nuclei of the SkMCs and ASMCs nuclei in the anterior wrist and medial malleolus within the electrical current pathway were obviously stretched, narrowed, and coalesced, presenting a nuclear polarization and arranging as line-like and moniliform patterns. The L/S axis ratio of those nuclei in the anterior wrist and medial malleolus were markedly increased as compared with the control group (p < 0.001). Through the ROC curve analysis, the critical diagnostic values of the L/S axis ratio of those nuclei were respectively 4.84 and 3.81. Conclusion These findings suggest that the soft tissues of the anterior wrist and/or the medial malleolus, as the narrowest parts of the limbs, could be used as the sites for tissue sampling and considered as necessary locations for histopathological examinations to determine the electrocution in medicolegal identification.

ObjectiveTo evaluate the clinical and radiographic efficacy and safety of the combination of recombinant human tumor necrosis factor-αt receptor Ⅱ IgG Fc fusion protein (rhTNFR:Fc) and methotrexate (MTX) in patients with rheumatoid arthritis (RA). MethodsThirty patients with highly active RA were treated with rhTNFR:Fc (25 mg subcutaneously twice weekly) and oral MTX (up to 15 mg weekly). Clinical efficacy was assessed using ACR response criteria and the disease activity score in 28 joints (DAS28).Radiographs of the hands and wrists were assessed with the modified Sharp score. Chi-square test, Fisher is exact test and paired t-test were performed. ResultsAt week 52, ACR20, ACR50 and ACR70 responses were achieved by 90%, 87% and 67% respectively. At week 52, mean DAS28 was 3.4±1.1 compared to 6.4±0.6 at base-line(P<0.01), with 23% patients achieving clinical remission and 17% patients in low disease activity. Similarly, the HAQ was improved significantly, declining from 1.18±0.56 at base-line to 0.25t±0.34 at week 52 (P<0.01). No radiographic progression was found in 22 cases. Adverse events were mild in general.ConclusionTreatment with rhTNFR:Fc plus MTX has shown good efficacy throughout 52 study period in reducing disease activity, improving function, and retarding radiographic progression. Combination therapy for 52 weeks can achieve disease remission and no radiographic progression, which are the two goals of therapy for RA.

Objective:
To learn the epidemiological characteristics of coronavirus disease 2019(COVID-19)in Huzhou,so as to provide reference for prevention and control of COVID-19.
Methods:
All the confirmed cases of COVID-19 in Huzhou,diagnosed according to the COVID-19 Diagnosis and Treatment Plan(Sixth Version Trial)and reported from January 25 to February 7,2020,were recruited. The process of diagnosis and treatment,clinical manifestation,exposure history and close contacts were collected to analyze the epidemiological characteristics.
Results:
On January 25,the first confirmed cases of COVID-19 in Huzhou was reported. By February 7,totally 10 confirmed cases were reported and no asymptomatic infection was found. They were all imported,including three Wuhan residents,two with a trip to Wuhan,three with a trip to Suizhou,one with a trip to Hangzhou and one with a trip to Thailand(two Wuhan passengers on the same flight). The ratio of male to female cases was 1∶1. The median age was 32 years old. Seven cases were found when they went to a doctor by themselves,and three cases were found during the quarantine. The main clinical manifestations were fever,dry cough and fatigue. The median time from onset to diagnosis was 3 days. By March 3,all the cases were discharged,with median course of 24 days. There were 312 close contacts,and all of them were released after 14 days of quarantine.
Conclusions
To prevent imported cases from outside and stop spread inside taken by Huzhou government was proved to be effective. All the COVID-19 cases in Huzhou were imported,mostly from Wuhan. No local cases were reported.
