The performance appraisal (PA) system establishment in scientific research institutes on traditional Chi-nese medicine (TCM) plays an important role in the management of TCM research work, which can set up both well-defined guidance and favorable appraisal regimen for scientific researchers, so that leads to the accomplishment of the scientific objectives. However, current PA system establishment has fallen seriously behind the real demand in most TCM research institutes. As a result, there is a serious lack of a mature, efficient, standardized, propagable PA system in TCM research field. In this paper, we tried to discuss the current situation and key issues in building modern PA system in TCM research institutes. The PA system development in scientific research institutes on TCM was pointed out. The PA system should be based on existed referenced similar platforms, with full consideration on professional features and Chinese culture. The PA system establishment should be with most science, systematicness, objectivity, and guidance. The PA system should also be established to evaluate the scientific researchers equitably, guide the scientific trend, provide proper institute, and promote scientific research.

Objective To seek the predictive value of pudendal nerve function that need preventive anti-incontinence surgery at the same time following pelvic prolapse surgery in severe pelvic organ prolapse (POP) patients. Methods Seventy women completed this study from January 2014 to June 2015 in Fuzhou General Hospital of Nanjing Military Command, dividing into four groups: POP with or without coexisting occult stress urinary incontinence (OSUI) in preoperation, women with persistent stress urinary incontinence (SUI) in postoperation, women without SUI in postoperation. The pudendal nerve function in preoperation was measured by using Solar Urodynamic Neuro Module, including pudendal nerve terminal motor latency (PNTML), and amplitude. Results There were statistical significance on bilateral PNTML between POP coexisting OSUI group and only severe POP group [(2.62±0.23) versus (2.40±0.26) ms in right of PNTML, (2.55 ± 0.21) versus (2.37 ± 0.30) ms in left of PNTML; all P<0.05], but no statistical significance on bilateral amplitude (P>0.05). Compared de novo SUI group with POP group in postoperation, de novo SUI group′s right of PNTML was significantly increased [(2.74 ± 0.16) versus (2.47 ± 0.26) ms; P<0.05]; and the right of PNTML was extending 2.5 standard deviation at least compared with the health′s [(2.10±0.20) ms]. Conclusions The PNTML of pudendal nerve of POP coexisting OSUI is severe than only severe POP, the velocity of nerve conduction is slowing, and PNTML extension has a predictive value for postoperative urinary incontinence. When the right of PNTML of preoperative POP increased by at least 2.5 standard deviations than health′s, the risk of SUI postoperative strongly increased, and a anti-incontinence surgery at the same time following pelvic prolapse surgery should be adviced.

Objective To investigate the correlation between the expression levels of semaphorin3A and MMP14,and their subsequent prognostic significance in nonsmall cell lung cancer(NSCLC).Methods The expression of semaphorin3A and MMP14 protein levels was analyzed in 94 cases of NSCLC tissues and in 80 cases of normal lung tissues,using immunohistochemistry(IHC).Correlation and survival analysis were used to further investigate their association and prognostic value.The correlation analysis using Pearson test,and log-rank test for survival analysis.Results The NSCLC tissues exhibited a lower expression of semaphorin3A and a higher expression of MMP14 than in the control lung tissues.The downregulation of semaphorin3A and upregulation of MMP14 may promote pleural invasion,lymph node metastasis,vascular invasion and proliferating cell nuclear antigen expression.The expression of semaphorin3A was correlated with the maximum diameter of tumor.There was a negative correlation between the protein expression levels of semaphorin3A and MMP14 in NSCLC tissues.Conclusion The data suggest that lower expression of semaphorin3A and a higher expression of MMP14 may promote occurrence and development in NSCLC and that the combined detection of semaphorin3A and MMP14 protein may be a helpful tool in predicting the prognosis of NSCLC.

In this study, the formulation and preparation process of curcumin nanocrystalline injection were optimized to improve curcumin dissolution rate and bioavailability in vivo.Media grinding method was used to prepare curcumin nanocrystals, and the particle size was used as the evaluation index.The Box-Behnken experimental design was used to optimize its formulation and preparation process, and to characterize its physical and chemical properties.In addition, the dissolution of nanocrystal with different particle sizes was investigated by the paddle method, and the pharmacokinetics in rats were studied.The experimental results showed that the optimal formula and process were obtained through Box-Behnken experimental design, and that uniform curcumin nanocrystals with an average particle size of 223.1 nm were obtained.The results of X-ray diffraction and differential scanning calorimetry analysis showed that the crystal form was stable during the preparation of nanocrystals. In vitro dissolution experiments with different particle sizes showed that the dissolution rate and the degree of dissolution would increase if the particle size was smaller.Pharmacokinetic studies in rats showed that cmax and AUC0-∞ of curcumin nanocrystal injection were 4.9 and 4.1 times that of curcumin raw materials, respectively.In summary, the curcumin nanocrystal injection developed in this research have a stable preparation process and can significantly improve the dissolution rate and bioavailability of the drug, which provides some ideas for the research on curcumin preparation.

Objective To evaluate the predictive values of albumin-bilirubin (ALBI) and easy albumin-bilirubin (EZ-ALBI) scores for early survival (postoperative 3 months) of recipients with liver failure after liver transplantation. Methods Clinical data of 137 recipients diagnosed with liver failure and underwent liver transplantation were retrospectively analyzed. The optimal cut-off values of preoperative ALBI, EZ-ALBI and MELD scores to predict early survival of recipients with liver failure after liver transplantation were determined by the area under the receiver operating characteristic (ROC) curve. The risk factors of early death of recipients with liver failure after liver transplantation were identified by univariate and multivariate Cox regression analyses. The effects of different ALBI and EZ-ALBI levels upon early prognosis of recipients with liver failure after liver transplantation were analyzed. Results The optimal cut-off values of ALBI, EZ-ALBI and MELD scores were 0.21, -19.83 and 24.36, and the AUC was 0.706, 0.697 and 0.686, respectively. Univariate Cox regression analysis showed that preoperative alanine aminotransferase(ALT)≥50 U/L, aspartate aminotransferase(AST)≥60 U/L, ALBI score≥0.21 and EZ-ALBI score≥-19.83 were the risk factors for early postoperative death of recipients with liver failure after liver transplantation (all P < 0.05). Multivariate Cox regression analysis demonstrated that preoperative ALBI score≥0.21 was an independent risk factor for early postoperative death of recipients with liver failure after liver transplantation (P < 0.05). According to the optimal cut-off value of ALBI score, the early survival rates in the ALBI < 0.21 (n=46) and ALBI≥0.21(n=91) groups were 93.5% and 64.8%, and the difference was statistically significant (P < 0.05). According to the optimal cut-off value of EZ-ALBI score, the early survival rates in the EZ-ALBI < -19.83(n=60) and EZ-ALBI≥-19.83(n=77) groups were 88.3% and 63.6%, and the difference was statistically significant (P < 0.05). Conclusions Preoperative ALBI score is of high predictive value for early survival of recipients with liver failure after liver transplantation, which could be utilized as a reference parameter for selecting liver transplant recipients.

Objective:To investigate the drug resistance and pathogenic mechanism of a uropathogenic Escherichia coli (UPEC) strain UPEC132 at the genome-wide level. Methods:The susceptibility of UPEC132 strain to 16 antimicrobial agents was determined by minimum inhibitory concentration (MIC) assay. The UPEC132 strain was genotyped by multilocus sequence typing (MLST). The three-generation sequencing platform was used to sequence and assemble the whole genome of the UPEC132 strain. Drug resistance and virulence gene function annotations were predicted by Prodigal software and screened by using genome database. Genome sequences of the UPEC132 strain and 23 other UPEC strains collected from GenBank were phylogenetically analyzed, and a phylogenetic tree was constructed by RAxML software.Results:The UPEC132 strain was resistant to ampicillin, ampicillin/sulbactam, tetracycline, erythromycin, chloramphenicol and cefazolin. Its genotype was ST10522 by MLST. The whole genome of the UPEC132 strain included one complete genome (chromosome) and two plasmid sequences. The sequence sizes of the chromosome and plasmids 1 and 2 were 5 234 468 bp, 117 139 bp and 101 356 bp, and the guanine-cytosine (GC) content was 50.48%, 49.05%, and 54.04%, respectively. There were 4 856, 140 and 116 genes annotated in the chromosome and plasmids 1 and 2, respectively. Drug resistance genes were mainly distributed in the chromosomal genome, mainly including the multidrug resistance efflux pump gene clusters. Only blaTEM-1 and tetG genes were carried in the plasmid 2. Virulence genes were also mainly distributed in the chromosome genome, including nine pilus adhesins, five iron uptake systems and three secretory toxins. Gene clusters encoding Afa and type Ⅳ fimbriae were located on plasmids 1 and 2, respectively. The phylogenetic tree showed that the UPEC132 strain was not in the same branch with either of the 23 UPEC strains. Conclusions:The UPEC132 strain belonged to ST10522, which was a newly named ST type of Escherichia coli and first reported at home and abroad. The genome-wide genetic information of the UPEC132 strain was fully revealed. The multidrug resistance genes and virulence genes carried by the UPEC132 strain were associated with its drug resistance and pathogenicity.

Objective:Based on UPLC-Q-TOF/MS, to screen a panel of plasma metabolite biomarkers for TB diagnosis and evaluate its diagnostic efficacy.Methods:102 active TB patients [49 males, 53 females, age 40.0(24.0, 48.5) years] from Shanghai Pulmonary Hospital and Shanghai East Hospital from January 2017 to January 2018, 100 TB-IGRA positive patients [55 males, 45 females, age 44.0(37.0, 52.0) years] and 96 healthy controls [55 males, 41 females, age 43.0(32.2, 52.8) years] from Shanghai East Hospital were randomly enrolled. UPLC-Q-TOF/MS technology was used to detect small molecule metabolites in plasma. Combined with multivariate statistical methods VIP and univariate statistic analysis Student's t-test, the main differential metabolites in the plasma of patients with active tuberculosis were filtered. The ROC curve was analyzed for the differential metabolites, and the AUC value, specificity, and sensitivity for diagnosis were used to screen metabolic biomarkers with diagnostic potential. Results:All the samples examined resulted in 10 266 variables, and 1 153 substances were identified by qualitative retrieval through the human metabolome database. After pairwise comparison of samples from the three groups, differential metabolites that simultaneously satisfied VIP > 1 and P<0.05 were plotted into a Venn diagram, and the resulting intersection set contained 38 major differential metabolites. The ROC curve analysis of 38 major metabolites showed that the area under the curve of lactic acid, dopamine, 9-pentadecenoic acid, and 12,13-dihydroxy octadecadienoic acid in the diagnosis of active tuberculosis were 0.92, 0.98, 0.94, and 0.94, respectively, the specificity was both more than 90% and the sensitivity was both more than 80%. The specificity and sensitivity of four metabolites in the combined diagnosis of active tuberculosis were both 94%. Conclusion:Lactic acid, dopamine, 9-pentadecenoic acid, and 12, 13-dihydroxy octadecadienoic acid can be used as potential metabolic biomarkers for tuberculosis diagnosis.

OBJECTIVETo explore the relationship between DNA mismatch repair (MMR) and clinicopathologic features and prognosis in patients with stages II and III colon cancers.

METHODSThe clinical and pathological data of 440 patients with stage II/III colon cancer after radical resection were retrospectively reviewed and analyzed. Immunohistochemical staining was used to assess the expression of MMR proteins (MLH1, MSH2, MSH6 and PMS2), and the correlation between DNA MMR and clinicopathological features and prognosis of colon cancers was analyzed.

RESULTSOf the 440 tumor samples tested for DNA mismatch repair status, 90 (20.5%) demonstrated defective DNA mismatch repair and 350 (79.5%) had proficient DNA mismatch repair. Defective DNA mismatch repair (dMMR) was associated with young patients (≤ 60), proximal colon cancer, stage II, poorly differentiated adenocarcinoma and mucinous adenocarcinoma (P<0.05 for all). Among the 440 patients, 126 (28.6%) cases had recurrence or metastasis and 93 (21.1%) died during the median follow-up of 61.0 months. The five-year disease-free survival (DFS) rate was 82.2% among the patients with tumor exhibiting dMMR, significantly higher than that in patients with tumors exhibiting pMMR (68.9%, P=0.02). The univariate and mutlivariate analyses showed that the MMR status is an independent factor affecting 5-year disease-free survival and overall survival (OS) in colon cancer patients (P<0.05 for both).

CONCLUSIONSDefective DNA mismatch repair (dMMR) is associated with patients with proximal colon cancer, stage II and poorly defferentiated adenocarcinoma and mucinous adenocarcinoma. The prognosis for patients with dMMR is better than those with pMMR. dMMR may be a useful biomarker for the prognosis of colon cancer.

Objective To evaluate transperineal sonography for lower urinary tract symptoms after pelvic floor reconstruction. Methods Eighty-three patients with severe pelvic organ prolapse received surgeries in Fuzhou General Hospital from September 2014 to September 2015, dividing into two groups:27 patients were selected to receive transvaginal mesh (TVM) pelvic floor reconstruction surgery with tension-free vaginal tape-Abbrevo (TVT-Abbrevo) incontinence surgery, named TVM+TVT-Abbrevo group;56 patients were selected to receive TVM pelvic floor reconstruction surgery only, named TVM group. The ultrasonic parameters at rest, on contraction and Valsalva condition respectively were observed and measured, including the bladder neck descent (BND), urethral rotation angle, retrovesical angle, levator urethra gap (LUG), the existence of bladder neck funneling, position of the tape, by using 2D and 3D transperineal ultrasound. Results The two groups were compared with the ultrasonic parameters before and after operation: two groups of patients with postoperative BND [(2.3 ± 0.5) versus (3.1 ± 0.7) cm, (1.6 ± 0.4) versus (3.6±0.4) cm] were significantly reduced, the difference was statistically significant (P=0.02, P<0.01). The two groups of LUG before and after operation [(3.62 ± 0.45) versus (3.26 ± 0.92) cm, (2.96 ± 0.47) versus (2.72 ± 0.38) cm] both had significant difference by maximum Valsalva (P<0.01, P=0.04). There was statistical significance difference of urethral rotation angle in TVM+TVT-Abbrevo group by maximum Valsalva (P=0.01). Observation of morphology:(1) 2 patients with difficulty in urination in TVM+TVT-Abbrevo group, ultrasound showed when the position of the bladder down the urethra discount;4 patients with stress urinary incontinence (SUI), ultrasound showed slings off or release. (2) One patient with difficulty in urination in TVM group, but ultrasound showed lower urinary tract anatomy were normal; 5 patients with SUI, ultrasound showed the position of the bladder neck were significantly lower in 3 patients, showing high mobility, and the other 2 patients had a larger urethral diameter, showing a tendency of natural deletion. Conclusions Anatomy of lower urinary tract could be clearly showed by transperineal sonography. This could provide imaging support for the diagnosis of lower urinary tract symptoms after pelvic floor reconstruction.
