Objective To establish the quality standard for Qingxin Anshen Soft Capsules. Methods Rhizoma Coptidis and Cortex Cinnamomi in Qingxin Anshen Soft Capsules were identified by TLC. Berberine hydrochloride and cinnamaldehyde were determined by HPLC. Results The characteristic identification by TLC was distinct and highly specific. The results of quantitative evaluation showed that berberine hydrochloride had the linear range of 0.6412 ?g~6.412 ?g(r=0.999 7,n=7),and the average recovery was 97.57 %(RSD=0.81,n=6);cinnamaldehyde had the linear range of 0.2148 ?g~2.148 ?g(r=0.999 8,n=7),and the average recovery was 97.70 %(RSD=0.88,n=6). Conclusion The method is reliable,accurate and specific. It can be used for the quality control of Qingxin Anshen Soft Capsules.

Objective :
To investigate the clinical and molecular epidemiological characteristics of 10 patients with enterovirus (EV)-D68 infections in the respiratory tract in Shaoxing City, Zhejiang Province, so as to provide insights into formulation of control interventions for EV-D68 infections.
Methods:
Clinical specimens were sampled from patients with acute respiratory tract infections (ARTIs) admitted to sentinel hospitals in Shaoxing City from 2021 to 2022, and EV-D68 was detected using real-time fluorescent PCR assay and sequencing of the VP1 region of enterovirus. The epidemiological and etiological characteristics of EV-D68 infected cases were descriptively analyzed.
Results:
A total of 3 009 specimens were sampled from patients with ARTIs from 2021 to 2022, and the detection of EV-D68 was 0.33%. Of all EV-D68-infected patients, there were 6 men and 4 women, and 5 cases under 18 years of age, 2 cases at ages of 18 to 60 years and 3 cases at ages of over 60 years. EV-D68 infection predominantly occurred in summer (5 cases detected between May and July) and autumn (5 cases detected between September and October). The main clinical symptoms included fever (10 cases), sore throat (9 cases) and cough (8 cases), and all 10 cases recovered well, with no deaths reported. Sequencing identified D3 subtype in all 10 specimens positive for EV-D68.
Conclusions
The ARTIs caused by EV-D68 occurred predominantly among children under 18 years of age in Shaoxing City, and was highly prevalent in summer and autumn. D3 was the predominant enterovirus subtype.

Objective:To probe into the mechanism of the formation of neuroma and stump pai n,and the development of nerve fibres after the proximal ends of peripheral nerv e were bridged by pedicled skeletal muscle.Methods:Forty Wister white rats were randomly divided into experimental group an d control group.The left sciatic nerves of all the rats were transected at the s ame level,and the distal parts of nerves were cut off. The proximal end of the t ransected sciatic nerve in th experimental group was longitudinally divided into two parts,and the two ends were bridged by pedicled skeletal muscle.The proxima l ends of sciatic nerves were left in situ.The sciatic nerves were detected afte r 16 weeks.Results:In experimental group,the regenerated nerve fibres grew into skeletal mu scle bridge via anastomosis and distributed among the skeletal fascicle,and ther e was no formation of neuroma.Conclusion:The pedicled skeletal muscle bridging of the proximal ends of the amp utated peripheral nerves may prevent the formation of neuroma.

Objective To observe the effects of enriched environment on cognitive function in mice with sepsis-associated encephalopathy and to study the neuron PAS domain protein 4 (NPAS4)/brain deprive neurotrophic factor (BDNF)related mechanisms.Methods Sixty adult male mice were divided randomly into three groups:sham operation with standard environment group (group SS,n =12),cecal ligation and puncture with standard environment group (group CS,n =24),cecal ligation and puncture with enriched environment group (group CE,n =24).All mice were reared in standard environment or enriched environment for 28 days.The fear condition test was conducted on day 29 af-ter operation in mice.The change of NPAS4 and BDNF,the density of dendritic spine were detected by western blot or golgi staining.Results Compared with group SS,the context freezing time, NPAS4 and BDNF expression and the density of dendritic spine in hippocampus decreased significantly in group CS (P < 0.05).Compared with group CS,the context freezing time,NPAS4 and BDNF expression and the density of dendritic spine in hippocampus increased significantly in group CE (P <0.05).No significant difference was observed in the conditional freezing time among three groups.Conclusion Enriched environment can obviously improve cognitive function impairment induced by sepsis-associated encephalopathy,which may be related with up-regulated expression of NPAS4/BDNF,and promoted synaptic plasticity.

Incidence of cancer is increasing year by year,diagnostic techniques are continually advanced,and the numbers of anti-cancer drugs are growing,but the efficacy has not been fundamentally improved.Surgery,chemotherapy and radiotherapy can only kill the part of mature tumor cells,but can not kill the cancer stem cells,and eventually leading to tumor recurrence.While acupuncture,qigong,psychology comprehensive treatment can inhibit tumor growth and reduce metastasis and recurrence,improve quality of life and prolong survival.We should update our recognition,to carry out the study on the treatment of tumor by TCM with large sample and multiple centers,to demonstrate its low toxicity,low costs and efficiency.
