Medical institutions, with their clinical practice foundation and abundant human use experience data, have become important carriers for the inheritance and innovation of traditional Chinese medicine(TCM) and the "cradles" of the preparation of new TCM. To effectively promote the transformation of new TCM originating from the TCM clinical practice in medical institutions and establish an effective evaluation index system for the transformation of new TCM conforming to the characteristics of TCM, consensus experts adopted the literature research, questionnaire survey, Delphi method, etc. By focusing on the policy and technical evaluation of new TCM originating from the TCM clinical practice in medical institutions, a comprehensive evaluation from the dimensions of drug safety, efficacy, feasibility, and characteristic advantages was conducted, thus forming a comprehensive evaluation system with four primary indicators and 37 secondary indicators. The expert consensus reached aims to encourage medical institutions at all levels to continuously improve the high-quality research and development and transformation of new TCM originating from the TCM clinical practice in medical institutions and targeted at clinical needs, so as to provide a decision-making basis for the preparation, selection, cultivation, and transformation of new TCM for medical institutions, improve the development efficiency of new TCM, and precisely respond to the public medication needs.

OBJECTIVES: To evaluate the ability of the ForenSeq^TM DNA Signature Prep kit (ForenSeq kit) in analyzing the sequence information of STRs in Zhejiang She ethnic group and its forensic application efficacy. METHODS: A total of 50 Zhejiang She ethnic group samples were sequenced with the ForenSeq kit on the MiSeq FGx platform. The data was analyzed using ForenSeq^TM universal analysis software to obtain the motif structure and flank regions of the 58 STRs, then compared with PCR-CE typing results to test the consistency. At last, the allele frequency and population genetic parameters were calculated. RESULTS: A total of 448 sequence polymorphic alleles were detected in 50 samples of Zhejiang She ethnic group. Compared with fragment length polymorphism detected by PCR-CE, 82 alleles were increased by MPS detection based on ForenSeq kit, and 7 SNPs variation were detected in the flanking regions of 6 loci. The 22 male individuals were genotyped, and total 19 haplotypes were detected in 24 Y chromosome STRs of these 22 males. The cumulative discrimination power of the 27 autosomal STRs was 1-8.87×10^-30, the cumulative probability of exclusion of duo-testing was 0.999 999 962 640 657, the cumulative probability of exclusion of trios-testing was 0.999 999 999 999 633. CONCLUSIONS Based on MPS typing technology, using the ForenSeq kit greatly improves the detection efficiency. In addition, the 58 STRs have good genetic polymorphisms in Zhejiang She ethnic group, which are suitable for individual identification and paternity identification in forensic application.

Objective To study the genetic polymorphism of whole mitochondrial DNA （mtDNA） genomes in She population in Zhejiang and to explore the maternal genetic structure of the She population. Methods Whole mtDNA genomes of 231 unrelated individuals from She population in Zhejiang Province were sequenced. The number of mutations and population genetics parameters such as, the haplotype diversity （HD）, discrimination power （DP）, and random match probabilities （RMP） were analyzed. The mtDNA haplogroups of Zhejiang She population were classified, and the maternal genetic relationships between She and nine other Chinese populations were estimated. Results In 231 Zhejiang She samples, 8 507 mutations （702 types） were observed and the samples were classified into 94 haplogroups. The HD, DP and RMP values were 0.998 6, 0.994 2 and 0.005 8, respectively. The lowest genetic differentiation degree （F_st=0.006 89） was detected between Zhejiang She population and southern Han population. Principal component analysis （PCA） and median-joining network analysis showed that the genetic distance of Zhejiang She population with Guangxi Yao, Yunnan Dai and Southern Han populations was relatively close, but the population still had some unique genetic characteristics. Conclusion The whole mtDNA genomes are highly polymorphic in Zhejiang She population. The Zhejiang She population contains complex and diverse genetic components and has a relatively close maternal genetic relationship with Guangxi Yao, Yunnan Dai and Southern Han populations. Meanwhile, Zhejiang She population has kept its unique maternal genetic components.

The aim of this paper was to investigate the effect of Schizonepetae Herba and Saposhnikoviae Radix(wind medicine) on the expression of AQP4 and AQP8 in colonic mucosa in rats with ulcerative colitis(UC). A total of 35 healthy SD male rats were randomly divided into normal group(gavaged with normal saline), DSS model group, as well as low, middle, and high dose wind medicine groups(Schizonepeta and Saposhnikovia 1∶1, gavaged at dosages of 6, 12, and 24 g·kg~(-1)·d~(-1)), with 7 in each group. UC rat model was established by free drinking of 3% dextran sulphate sodium(DSS) solution for 10 days. At the end of the 10 th day after the treatment, mice were put to death to collect colonic mucosa. The length of colon was measured; the colonic mucosal injury index(CMDI) and pathological changes of colon were observed. ELISA method was used for measuring the content of serum IL-1, IL-8, and immunohistochemical method was used to measure AQP4, AQP8 protein expressions in colon mucosa. The expressions of AQP4, AQP8 mRNA were measured by Real-time PCR. As compared with the normal group, the length of colon tissue was significantly reduced(P<0.01), CMDI scores and pathological scores were significantly increased(P<0.01), the levels of serum IL-1 and IL-8 were significantly increased(P<0.05) in model group; the immunohistochemical results showed that the protein expressions of AQP4, AQP8 were lower; the color was light yellow or brown; AQP4, AQP8 mRNA expressions in colon mucosa were significantly decreased in model group(P<0.01). CMDI scores, pathological scores, and the levels of serum IL-1, IL-8 in high, middle, low dose wind medicine groups were obvious lower than those in the model group(P<0.01 or P<0.05); the protein expressions of AQP4, AQP8 were higher; the color was chocolate brown or dark brown; the length of colon tissue, and the expressions of AQP4, AQP8 mRNA were obvious higher in wind medicine groups(P<0.01 or P<0.05). Schizonepetae Herba and Saposhnikoviae Radix could significantly improve the symptoms and histopathology of UC model rats and accelerate the intestinal mucosal healing. The mechanism may be related with up-regulating the expression level of AQP4 and AQP8 in colonic mucosa.

Objective To validate the accuracy and reliability of structured-light three-dimensional （SL-3D） scanning in measuring the length and area of the regular and irregular scars on body surface and discuss its value in forensic practice. Methods The lengths of 30 cases of simulated linear scars and 50 cases of linear scars after injury were measured using soft ruler, vernier caliper + thin line method, and SL-3D scanning. The areas of 35 cases of simulated patchy scars and 15 cases of patchy scars after injury were measured using length × width, film tracing with coordinate paper method, pixel method, and SL-3D scanning, and then statistically analyzed. Results The differences between the length of the simulated linear scars measured by SL-3D scanning and standard length had no statistical significance. When simulated patchy scars and patchy scars after injury were measured with high surface curvature and large irregular areas, the differences between the results of SL-3D scanning measurement and the standard area had no statistical significance. When the length of 50 cases of linear scars after injury were measured using SL-3D scanning, the correlation coefficient between the measurement results of two different investigators was 0.998, and the correlation coefficient between the two measurement results by the same investigator was 1.000. The correlation coefficient between the results of SL-3D scanning and that of vernier caliper + thin line method was 0.996. Conclusion The three-dimensional information of the scars on the body surface can be acquired using SL-3D scanning. The measurement of the length and area of the scars is not influenced by the location of scars, curvature of surface, and human factors. The measurement results are accurate, reliable and has unique advantages.

Objective To explore the influencing factors and correlation of positive surgical margin (PSM) and biochemical recurrence (BCR) in men after robot-assisted radical prostatectomy (RALP).Methods The clinical data of 190 patients with local or locally advanced prostate cancer who underwent RALP by single surgeon in the Department of Urology of Changhai Hospital from January 2016 to September 2017 were collected.Age was (67.5 ±6.9) years old;median body mass index (BMI),preoperative PSA,prostate weight were 24.2 kg/m2 (16.6-34.2 kg/m2),15.0 ng/ml (1.41-393.94 ng/ml) and 36.9 g (8.65-207.58 g) respectively.The group of surgical margin was divided into negative surgical margin,apex-only PSM,base-only PSM as well as apex and base PSM.Characteristics between patients stratified by surgical margin or BCR were compared using x2 test.The influencing factors of PSM were analyzed by logistic regression.Cox regression was used for the analysis of predictive factors of BCR.Log-rank test and Kaplan-Meier curves were used for comparing the BCR rate between the groups of surgical margin.Results Of all the 190 enrolled patients,total PSM rate was 24.7％ (47/190),apex-only PSM rate was 13.2 ％ (25/190),base-only PSM rate was 5.8％ (11/190),apex and base PSM rate was 5.8 ％ (11/190).Multivariate analysis showed the independent predictive factors influencing PSM were preoperative PSA (P =0.048) and pathological stage (P =0.004).The median follow-up period was 7.3 months (0.9-26.6months) and BCR happened in 19.5％ (37/190) patients.The rates of BCR were 15.4％ (22/143),16.0％ (4/25),27.3％ (3/11) and 72.7％ (8/11) in the patients with negative surgical margin,apexonly PSM,base-only PSM and both apex and base PSM respectively.Log-rank test revealed that the rate of BCR in patients with apex and base PSM was higher than that in patients with negative surgical margin (P ＜0.001) or patients with apex-only PSM(P =0.002).Cox analysis indicated that higher preoperative PSA (P =0.040),higher pathological stage (P =0.041) and higher pathological Gleason score (P =0.004) were the independent predictors of BCR.PSM was not a predictive factor of BCR (P =0.257).Conclusions Preoperative PSA and pathological stage are the influencing factors of PSM.Higher preoperative PSA,higher pathological stage and higher pathological Gleason Score are the predictive factors of BCR.PSM may not be a predictive factor of BCR.The relationship between PSM and BCR needs further study.

A retrospective analysis was performed for the clinical data of four children with Epstein-Barr virus (EBV)-related acute liver failure. There were two boys and two girls with a median age of 10 months (range 8.5-44 months). Of the four children, three were diagnosed with infectious mononucleosis (IM), among whom two met the diagnostic criteria of hemophagocytic lymphohistiocytosis (HLH), and one was diagnosed with past EBV infection. All the children had positive EBV DNA in blood and all had pyrexia, hepatomegaly, and jaundice on admission. Three children had the symptom of splenomegaly, ascites, or vomiting. Two children had enlargement of cervical lymph nodes, skin rash, or pleural effusion. One child had gastrointestinal bleeding or stage 2 hepatic encephalopathy. All the children had an abnormal lymphocyte count of <10%, and only one child had leukocytosis and thrombocytopenia. Among the four children, alanine aminotransferase level increased by 10-100 times; total bilirubin level increased by 3-5 times; lactate dehydrogenase level increased by many 10 times; prothrombin time prolonged significantly. All the children were given antiviral therapy with intravenously injected acyclovir or ganciclovir, as well as hepatocyte growth factor to promote hepatocyte growth and hormone to alleviate inflammatory response. Two children were given plasma exchange in addition, among whom one was given the combination of continuous venovenous hemodiafiltration. Two children with HLH were given chemotherapy according to the HLH-2004 regimen. Three children survived, and one child with HLH died of multiple organ failure. It is concluded that EBV infection can cause acute liver failure and that early use of multimodality therapy including blood purification may be beneficial for prognosis in these children.

OBJECTIVETo investigate the association between rs9722 polymorphisms in the S100B gene and hand, foot and mouth disease (HFMD) caused by enterovirus 71.

METHODSA total of 124 HFMD children with enterovirus 71 infection were enrolled as subjects, and 56 healthy children were enrolled as control group. The rs9722 polymorphisms in the S100B gene were detected for both groups, and the serum level of S100B protein was measured for 74 HFMD children.

RESULTSThe rs9722 locus of the S100B gene had three genotypes, CC, CT, and TT, and the genotype frequencies were in accordance with Hardy-Weinberg equilibrium. Compared with the control group, the HFMD group had significant increases in the frequencies of TT genotype and T allele (P<0.01). Children with severe HFMD caused by enterovirus 71 infection had significantly higher frequencies of TT genotype and T allele than those with moderate or mild HFMD (P<0.05). Compared with the cured patients, the patients with poor prognosis had significant increases in the frequencies of TT genotype and T allele in the rs9722 locus of the S100B gene (P<0.05). Among the 74 children with HFMD, the children with TT genotype had the highest serum level of S100B protein, and those with CC genotype had the lowest level (P<0.01).

CONCLUSIONST allele in the rs9722 locus of the S100B gene might be a risk factor for severe HFMD caused by enterovirus 71 infection.
