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.

Objective To explore the standardized process and method of atrial septum puncture(ASP)in swine guided by X-ray fluoroscopy and make ASP more safe and effective.Methods ASP was performed in 48 Pudong swines guided by X-ray fluoroscopy.Three protocols for precise location of atrial septal puncture points were recommended.(1)Site of atrial septal puncture point in cranial-caudal direction was determined under posterior-anterior projection,which was confined to the cranial side of the coronary sinus(CS)orifice at a distance of 1 cone body height along the midline of spine.(2)With 10° intervals,the fluoroscopy of the CS catheter was completed according to the right anterior oblique 10°～60° and the left anterior oblique 10°～60°,and the connection line of the CS 5-6 and 7-8 electrodes was perpendicular to the oval fossa,so as to confirm the perspective angle of the CS 5-6 and 7-8 electrodes in the same straight line.(3)The arch feature of puncture needle and distal part of sheath turned into a straight line under the perspective angle,of which the CS 5-6 and 7-8 electrodes were in the same straight line.Results ASP was successfully performed in 48 Pudong swines without any complications.Echocardiography showed left to right shunt through atrial septum after ASP.The average time of ASP was(25.7±11.5)minutes,the average X-ray exposure time is(14.0±3.4)min and the average radiation dose was(47.6±20.2)Gmy.Conclusions Using the coronal sinus electrode as a reference,atrial septal puncture in swine guided by X-ray fluoroscopy was safe and reliable.

Objective To understand the contamination status of common food-borne pathogens in foods sold in Changzhou, and to provide evidence for food safety risk assessment and prevention of food-borne diseases. Methods From 2010 to 2020 , 2 513 samples of 17 types of foods were collected in Changzhou area. The detection of pathogenic bacteria was carried out in accordance with the standard operation procedure specified in the ^“Workbook for Surveillance on Food Microorganisms and Pathogenic Factors in Jiangsu Province^”. Results A total of 260 positive samples of common food-borne pathogens were detected in all 2 513 samples with an overall detection rate of 10.30%. Single factor analysis showed that the detection rate of pathogenic bacteria in non-ready-to-eat samples was higher than that in ready-to-eat samples (χ²=148.875，P =0.000). The detection rate of pathogenic bacteria in bulk samples was higher than that in prepackaged ones (χ²=70.956，P=0.000). There is a difference in the detection rate of food-borne pathogens from different types of sampling sites (χ²=65.017，P=0.000). Logistic regression analysis showed that ready-to-eat food, packaging type, and sampling season were significantly correlated with the detection rate of food-borne pathogens. The detection rate of pathogenic bacteria in samples collected in the third or fourth quarters was higher than that in the first quarter. Conclusion The commercial foods sold in Changzhou have a relatively high level of contamination of food-borne pathogenic bacteria, and they should be fully heated and sterilized before consumption. The relevant departments should strengthen supervision and health education in summer and autumn.

Objective:To investigate the combination of internal fixation for periprosthetic fractures of the proximal femur (PFFF) after hip arthroplasty.Methods:The data of 58 patients with periprosthetic fractures after hip arthroplasty from May 2008 to March 2022 were retrospectively analyzed, including 31 males and 27 females. The average age was 75.5±18.2 years (range, 35-95 years). There were 39 total hip arthroplasty and 19 hemiarthroplasty; 37 biological prosthesis and 21 cemented prosthesis. Intraoperative periprosthetic fractures occurred in 6 cases and 52 cases postoperatively. Unified classification system (UCS): UCS IV.3A1 type 2 cases, 3A2 type 1 case, 3B1.1 type 19 cases, 3B2.1 type 25 cases, 3B3 type 2 cases, 3C type 9 cases. Fracture site: 3 cases in zone A (greater trochanter), 46 cases in zone B (around the femoral stem), and 9 cases in zone C (distal to the tip of the femoral stem. Internal fixation is composed of primary and secondary fixation, the main fixation method was the cerclage of steel wire or titanium cable, locking compression plate, and locking attachment plate fixation. The secondary fixation method was the cerclage of titanium cable, which was required to cover three zones A, B and C to form an overall balanced fixation. The modified Harris hip scores (mHHS), plate length, working length and screw number of different internal fixation combinations were compared.Results:The follow-up time was 54.2±21.6 months (range, 11-86 months). All patients showed signs of fracture healing at 10.2±1.5 weeks (range, 7-13 weeks) after operation, and bony union was observed at 19.6±1.3 weeks (range, 17-22 weeks) after operation. No delayed union or nonunion was observed. After operation, one case had a stress fracture and was revised with double-plate internal fixation; one case had a failed internal fixation and was revised with double-plate internal fixation and a large allograft bone graft. The mHHS score of UCSIV.3B2.1 group (80.3±4.6) was the lowest at 6 months after operation, and the difference between the groups of different types was statistically significant ( F=256.72, P<0.001). The score of simple internal fixation group (91.6±4.2) was higher than that of revision combined with internal fixation group (81.9±4.1), and the difference was statistically significant ( t=8.32, P<0.001). The plate length and working length were 24.9±2.5 cm and 12.6±1.7 cm for UCS IV.3B1.1, 25.4±2.6 cm and 13.6±1.8 cm for 3B2.1 and 28.1±2.5 cm and 4.9±1.9 cm for 3C, respectively ( F=5.33, P=0.005; F=6.78, P<0.001). The number of screws in zone A was significant difference among different UCS types ( F=52.67, P<0.001); UCS IV.3B1.1 (6.5±2.3) and 3B2.1 (6.7±2.2) were more than 3B3 (3.5±1.5) and 3C (3.7±1.6). The number of screws in zone B was significant difference among different UCS types ( F=42.15, P<0.001); The number of UCS IV.3B1.1 (2.3±1.6) and 3B2.1 (2.8±1.9) were significantly more than that of 3B3 (1.0±0.5) and 3C (1.2±0.6). The number of screws in zone C was significant differences among different UCS types ( F=39.62, P<0.001); The number of UCS IV.3B1.1 (3.8±1.9) and 3B2.1 (3.9±1.7) were more than that of 3B3 (2.0±0.5), the difference was statistically significant ( P<0.05). Conclusion:The function of hip after simple internal fixation of proximal femoral periprosthetic fractures was better than that of those who underwent revision at the same time; the number of screws of UCSIV.B1 and B2 is more than that of B3.

This study explored the genetic characteristics of the whole genome sequences of coxsackie virus A6 strains in Jiangsu province from 2013 to 2022,and analyzed the genetic evolution of each coding region of the full-length genome.To in-vestigate why coxsackievirus A6 has replaced enterovirus A71 and coxsackievirus A16 as the most predominant etiological agent for HFMD in Jiangsu province,we selected 35 CVA6 isolates circulating in Jiangsu province during 2013-2022 for whole ge-nome sequence amplification and analysis.Sequence alignment,homology analysis,phylogenetic analysis and genetic recombi-nation were performed with the DNASTAR,MEGA7.0 and similarity plots 3.5.1 software packages.We analyzed the impor-tant amino acid sites of CV-A6 in the Pl region and 3D region.The nucleotide and amino acid similarities of 35 CV-A6 full-length genomes were 87.5％-99.6％ and 97.0％-99.8％,respectively,and the nucleotide and amino acid sequence identity with the CV-A6 prototype strain was 80.3％-81.0％ and 94.7％-95.3％,respectively.On the basis of phylogenetic analysis of VP1 region sequences,the 34 CV-A6 strains in this study belonged to the D3a genotype,and only one strain belonged to the D2 genotype.According to the phylo-genetic analysis of 3D region sequences,four recombinant forms(RFs),RF-A,RF-L,RF-K and RF-C,appeared primarily in 2013-2022 in Jiangsu province.Recombination analysis demonstrated that CVA6s,which was prevalent in Jiang-su from 2013 to 2022,had high similarity to the CVA6 prototype strain Gdula in the structured protein sequences.However,in the non-structured protein sequences and noncoding regions,similarities were higher among CVA6s and prototype strains of other EV-A types.Amino acid mutation site analysis showed that multiple amino acid sites in the Pl and 3D regions varied fre-quently with respect to the prototype strain Gdula.These differences might have resulted in small changes in the capsid struc-ture and potential receptor-binding sites.In conclusion,by analyzing the whole genome sequence of CV-A6,this study advances understanding of the gene recombination and genetic evolution relationship of CV-A6 in Jiangsu Province;in addition,it may explain possible reasons why CV-A6 has become the main pathogen of HFMD in recent years,and it provides basic data for the prevention and control of CV-A6.

Objective:To explore the efficacy of elective nodal irradiation (ENI) and involved field irradiation (IFI) combined with chemotherapy in treatment of esophageal cancer.Methods:A total of 104 patients with esophageal cancer in Affiliated Hospital of Jiangnan University from May 2018 to May 2020 were selected as subjects for prospective study. All patients were randomly divided into observation group and control group by lottery method with 52 cases in each group. The target volume of observation group was delineated with IFI, and the control group was delineated with ENI. The curative effects, the levels of serum tumor markers [carbohydrate antigen 50 (CA50), squamous cell carcinoma (SCC) and carcinoembryonic antigen (CEA)] before and after treatment, the 1-year overall survival (OS) rate, the incidence of adverse reactions and the scores of various dimensions of health survey summary (SF-36) after treatment were compared between the two groups.Results:The total effective rate in the observation group was 90.38% (47/52), the total effective rate in the control group was 84.62% (44/52), and the difference was not statistically significant ( χ2 = 0.79, P =0.374). There was no statistical difference in CA50, CEA, SCC levels between the two groups before and after treatment (all P > 0.05). After treatment, the CA50, CEA and SCC levels in the two groups were lower than those before treatment, and the differences were statistically significant (all P < 0.05). The 1-year OS rate of the observation group was 94.23%, the control group was 90.38%, and the difference in OS between the two groups was not statistically significant ( χ2 = 0.54, P = 0.462). The incidence of acute radiation esophagitis in the observation group was lower than that in the control group, and the difference was statistically significant ( P < 0.001). There was no statistical difference between the two groups in SF-36 scale scores of physical functioning, role-physical, bodily pain, mental health, vitality, social functioning, role-emotional, and general health after treatment (all P > 0.05). Conclusions:Both ENI and IFI are effective treatments for patients with esophageal cancer. There is no significant difference in the quality of life of patients between the two delineation methods, but the incidence of acute radiation esophagitis is lower in patients with IFI regimen.

OBJECTIVE: To explore the effect of lenalidomide on human fibroblast-like synovial cells (HFLS) and the therapeutic efficacy on hemophilic arthropathy in hemophilia A mice model. METHODS: In vitro, to remodel the inflammatory environment of synovial tissue after hemorrhage, ferric citrate and recombinant TNF-α were added into the cell culture medium of HFLS. Cell Counting Kit-8 (CCK-8), Enzyme-linked immunosorbent assay (ELISA), Quantitative Real-time PCR (RT-qPCR) and flow cytometry were employed for detection of the effects of lenalidomide on the proliferation ability, pro-inflammatory cytokines release and apoptosis of HFLS cells. In vivo, hemophilia arthropathy was remodeled in hemophilia A mice by induction of hemarthrosis. A series of doses of lenalidomide (0.1, 0.3 and 1.0 g/kg) was administrated intra-articularly. Tissues of knee joints were collected on the 14th day after administration, and the protective effect of lenalidomide on arthritis in hemophilia A mice were evaluated by RT-qPCR and histological grading. RESULTS: In vitro, compared with the untreated control group, lenalidomide could significantly inhibit the proliferation of HFLS cells (P<0.05), and the effect was the most significant when the concentration was 0.01 μmol/L (P<0.001). Compared with the control group, lenalidomide could significantly inhibit the expression levels of TNF-α, IL-1β, IL-6 and IFN-γ in HFLS cells (P<0.05). The flow cytometry results showed that lenalidomide could enhance the apoptotis of HFLS cells (P<0.05). The results of RT-qPCR showed that lenalidomide could significantly reduce the mRNA expression levels of TNF-α, IL-1β, IL-6,MCP-1 and VEGF in the joint tissues (P<0.05). Histological results showed that compared with the injured group, lenalidomide could significantly reduce the pathological sequela after hemarthrosis induction, e.g. synovial thickening and neo-angiogenesis in the synovium. The protection displayed a dose-response pattern roughly. CONCLUSION In vitro, lenalidomide can inhibit the proliferation of HFLS cells, promote their apoptosis, and inhibit the expression of pro-inflammatory cytokines. In vivo, lenalidomide can significantly decrease the expression of pro-inflammatory cytokines in the joints of mice, and prevent the development of inflammation and neo-angiogenesis. The results provide a theoretical and experimental basis for the clinical application of lenalidomide in the treatment of hemophilic arthropathy.

OBJECTIVE: To examine whether the combination of Naoxintong Capsule with standard care could further reduce the recurrence of ischemic stroke without increasing the risk of severe bleeding. METHODS: A total of 23 Chinese medical centers participated in this trial. Adult patients with a history of ischemic stroke were randomly assigned in a 1:1 ratio using a block design to receive either Naoxintong Capsule (1.2 g orally, twice a day) or placebo in addition to standard care. The primary endpoint was recurrence of ischemic stroke within 2 years. Secondary outcomes included myocardial infarction, death due to recurrent ischemic stroke, and all-cause mortality. The safety of drugs was monitored. Results were analyzed using the intention-to-treat principle. RESULTS: A total of 2,200 patients were enrolled from March 2015 to March 2016, of whom 143 and 158 in the Naoxintong and placebo groups were lost to follow-up, respectively. Compared with the placebo group, the recurrence rate of ischemic stroke within 2 years was significantly lower in the Naoxintong group [6.5% vs. 9.5%, hazard ratio (HR): 0.665, 95% confidence interval (CI): 0.492-0.899, P=0.008]. The two groups showed no significant differences in the secondary outcomes and safety, including rates of severe hemorrhage, cerebral hemorrhage and subarachnoid hemorrhage (P>0.05). CONCLUSION The combination of Naoxintong Capsule with standard care reduced the 2-year stroke recurrence rate in patients with ischemic stroke without increasing the risk of severe hemorrhage in high-risk patients.

Objective: To investigate the incidence and risk factors of deep venous thrombosis (DVT) of lower extremity in patients with stage Ⅲ and Ⅳ pressure ulcer on admission. Methods: A retrospective case series study was conducted. A total of 241 patients with stage Ⅲ and Ⅳ pressure ulcers who met the inclusion criteria and were discharged from the Department of Wound Repair of the First People's Hospital of Zhengzhou from January 1, 2015 to December 31, 2019 were enrolled in this study, including 134 males and 107 females, aged 22 to 93 years, with a median age of 68 years; 37 patients were with stage Ⅲ pressure ulcers and 204 patients were with stage Ⅳ pressure ulcers. The DVT occurrence of patients was recorded. According to whether DVT of lower extremity veins was diagnosed by color Doppler ultrasound within 48 h after admission or not, the patients were divided into DVT group (n=37) and non-DVT group (n=204). Data of patients in the two groups were collected and compared, including gender, age, duration of pressure ulcer, time in bed, and combination with diabetes, hypertension, coronary heart disease, cerebral infarction, pneumonia, sepsis/septic shock, and paraplegia, and the plasma D-dimer level and Caprini score within 24 h after admission. Data were statistically analyzed with independent sample t test, Mann-Whitney U test, chi-square test, and Fisher's exact probability test. The indicators with statistically significant differences between the two groups were analyzed with multivariate logistic regression analysis to screen the independent risk factors influencing the DVT of lower extremity in 241 patients with stage Ⅲ and Ⅳ pressure ulcers on admission. Results: The incidence of DVT of lower extremity was 15.4% (37/241), of which 86.5% (32/37) were asymptomatic DVT. Among the DVT of 46 lower limbs, only 29 involved the inferior genicular veins, accounting for 63.0%. There were no statistically significant differences in gender, duration of pressure ulcer, combination with diabetes, hypertension, coronary heart disease, cerebral infarction, pneumonia, and sepsis/septic shock of patients between the two groups (P>0.05), while there were statistically significant differences in age, time in bed, combination with paraplegia, the plasma D-dimer level and Caprini score of patients between the two groups(t=-3.19, Z=-2.04, χ²=4.44, Z=-3.89, t=-2.14, respectively, P<0.05 or P<0.01). Multivariate logistic regression analysis showed that age and plasma D-dimer level were independent risk factors influencing the DVT of lower extremity in 241 patients with stage Ⅲ and Ⅳ pressure ulcers on admission (with odds ratios of 1.03 and 1.18, respectively, with 95% confidence intervals of 1.00-1.06 and 1.05-1.33, respectively, P<0.05 or P<0.01). Conclusions: The patients with stage Ⅲ and Ⅳ pressure ulcers have a higher incidence of DVT on admission, with age and plasma D-dimer level being the independent risk factors for DVT of lower extremity. It is necessary to pay attention to the targeted screening of DVT and education of its prevention.

Bivalves are species-rich mollusks with prominent protective roles in coastal ecosystems.Across these ancient lineages,colony-founding larvae anchor themselves either by byssus produc-tion or by cemented attachment.The latter mode of sessile life is strongly molded by left-right shell asymmetry during larval development of Ostreoida oysters such as Crassostrea hongkongensis.Here,we sequenced the genome of C.hongkongensis in high resolution and compared it to reference bivalve genomes to unveil genomic determinants driving cemented attachment and shell asymmetry.Importantly,loss of the homeobox gene Antennapedia(Antp)and broad expansion of lineage-specific extracellular gene families are implicated in a shift from byssal to cemented attachment in bivalves.Comparative transcriptomic analysis shows a conspicuous divergence between left-right asymmetrical C.hongkongensis and symmetrical Pinctada fucata in their expression profiles.Especially,a couple of orthologous transcription factor genes and lineage-specific shell-related gene families including that encoding tyrosinases are elevated,and may cooperatively govern asymmet-rical shell formation in Ostreoida oysters.
