OBJECTIVETo evaluate the efficacy of Chinese medicine (CM) combined adjuvant chemotherapy in postponing relapse and metastasis of radical resected Ib-IIIa stage non-small cell lung cancer (NSCLC) patients, and to explore its effect in improving their quality of life (QOL) and clinical symptoms.

METHODSWe designed a cohort study of 336 radical resected Ib-IIIa NSCLC patients by analyzing disease free survival (DFS) using Log-rank test. They were randomly assigned to the control group (155 cases, treated by adjuvant chemotherapy group) and the test group (181 cases, treated by adjuvant chemotherapy combined CM). By using controlled method, 60 radical resected NSCLC patients undergoing NP/NC program in 2012 (vinorelbine 25 mg/m2, combined with cisplatin 75 mg/m2 on day 1 and day 8/on day 1 or on day 1, 2, and 3; or carboplatin AUC = 5 on day 1) were assigned to the control group (29 cases) and the test group (31 cases). QOL scores (using EORTC QLQ-LC43 questionnaire) and TCM symptoms scores were compared between the two groups before chemotherapy, peri-chemotherapy (one day before the 2nd course of chemotherapy) , and after chemotherapy (20 days after ending the 4th course of chemotherapy).

RESULTS(1) The median DFS was longer in the test group than in the control group, but with no statistical difference between the two groups (42.73 months vs 35.57 months , P = 0.179). In the subgroup analysis, there was statistical difference in IIIa stage DFS. The median IIIa stage DFS of was longer in the test group than in the control group with statistical difference (27.87 months vs 19. 93 months, P = 0.047). (2) In the control study, repeated measured data indicated there was significant difference in physical functions between the two groups (P < 0.05). Total scores for health states decreased more in the test group than in the control group, but with no statistical difference (P > 0.05). Scores for constipation and CM syndrome scores were higher in the test group than in the control group (P < 0.05).

CONCLUSIONSCM had advantages in postponing DFS of radical resected NSCLC patients, especially in IIIa stage. CM could improve their QOL and clinical symptoms during adjuvant chemotherapy.

TNKSs are members of poly ( ADPribose) polymera-ses, which are different from other members of the PARP family with two unique structures: SAM domain and ankyrin repeat re-gion. TNKS participates in a variety of cellular function regula-tion, including telomere’ s dynamic balance, Wnt signaling pathways, glucose metabolism and spindle formation during mi-tosis. TNKS, as a very attractive drug target, regulates the sta-bility of target proteins via poly ( ADP-ribosylation). In recent years, the significant progress has been made for PARP inhibi-tors in cancer treatment. Multiple PARP inhibitors have entered different clinical evaluation stages. AstraZeneca's Olaparib, Clo-vis's Rucaparib, Merck's Niraparib come into existence in the market. This paper summarizes the recent studies of TNKS and its related inhibitors.

OBJECTIVETo investigate the correlation between nonalcoholic fatty liver disease (NAFLD) and three anthropometric indices, namely waist to hip ratio (WHR), body mass index (BMI) and waist to height ratio (WHtR).

METHODSThis retrospective case-control study involved 77 NAFLD patients and 50 patients without such disease, and their data of the 3 anthropometric indices were collected. Risk correlation analysis and Mantel-Haenszel chi-square test were used for correlation analysis.

RESULTSNAFLD was significantly correlated to WHR (chi(2)(MH)=59.609, P<0.001; odds ratio=30.522, 95% CI 12.815-72.695), WHtR (chi(2)(MH)=45.316, P<0.001; odds ratio=21.037, 95% CI 8.665-51.072) and showed a dose-response relationship with BMI (chi(2)=25.017, P<0.001).

CONCLUSIONThese results support a close correlation between NAFLD and the 3 anthropometric indices, indicating that BMI, WHR and WHtR can be significant predictors of NAFLD and have potential value for evaluating and predicting NAFLD.

OBJECTIVETo investigate the antimicrobial resistance and penicillin resistance-associated genes (TEM and pbp2B) of Streptococcus pneumoniae (S. pneumoniae) isolated from sputum specimens of Guangzhou children with respiratory tract infection.

METHODSE-test and Kirby-Bauer methods were applied to detect the antibiotic susceptibility of 44 strains of S. pneumoniae. PCR was used to detect resistance genes pbp2B and TEM, followed by DNA sequence analysis of pbp2B gene. The sequence results were compared to those of penicillin-susceptible S. pneumoniae R6.

RESULTSOf the 44 isolates of S. pneumoniae, only 5 (11.4%) were susceptible to penicillin. All strains were resistant to erythromycin but susceptible to ofloxacin and vancomycin. The resistance rate of the isolates to clindamycin and trimoxazole was more than 90%. The S. pneumoniae isolates showed a high susceptibility to amoxicillin, imipenem and ceftriaxone, with a resistance rate of 0, 2.6% and 3.9%, respectively. The sequence analysis showed that more than 99% nucleotide sequence of pbp2B gene of five penicillin-susceptible isolates was the same as penicillin-susceptible S. pneumoniae R6, without any amino acid replacement. Site mutation was found in the remaining 39 penicillin-nonsusceptible isolates with a nucleotide mutation rate ranging from 13.2% to 23.1% and amino acid replacement rate from 6.5% to 10.9%. The 39 penicillin-nonsusceptible isolates were classified into 4 types according to the mutation site between Ser391 and Thr492 of pbp2B: type I (n=30), type II (n=7), type III (n=1) and type IV (n=1). No TEM gene was detected in all the 44 S. pneumoniae isolates.

CONCLUSIONSThe S.pneumoniae isolates from Guangzhou children with respiratory tract infection are resistant to penicillin and erythromycin. Amoxicillin and the third generation cephalosporin may be recommended for treating S. pneumoniae infection. The mutation of pbp2B gene plays an important role in the development of S. pneumoniae resistance to penicillin.

Objective To study the bactericidal efficacy of hospital commonly used disinfectants such as ethanol,3" chlorine tablets,iodophor,glutaraldehyde,and avagard instant hand antiseptic on Staphylococcus aureus (S.a ureus) from different sources of hospital,and provide scientific basis for effective control of healthcare-associated infection(HAI).Methods A total of 48 strains of S.aureus from inpatients,hands of health care workers,and environment surface in the First Affiliated Hospital of Nanchang University were collected.Disinfectant was directly contacted with bacteria,in vitro killing efficacy of disinfectant on S.aureus from different sources at different diluted concentrations,and different contact time were studied.Results The killing rate of 5g/L iodophor,20g/L glutaraldehyde,and avagard instant hand antiseptic(0.5％ chlorhexidine + 70％ ethanol) to S.aureus with a 5-minute contact time was 100％;killing rates of 70％ ethanol and 1g/L 3" chlorine tablets to S.aureus with a 5-minute contact time were 96.5 ％-99.8 ％;but highly diluted iodophor,glutaraldehyde,and avagard instant hand antiseptic still could not completely kill S.aureus even the contact time was extended.Conclusion The routine use of disinfectants in the hospital can meet the clinical bactericidal efficacy,it is necessary to monitor concentration routinely,avoid decreasing sterilization ability.

BACKGROUNDIsocitrate lyase (ICL) was previously demonstrated to play a pivotal role in the intracellular metabolism of Mycobacterium tuberculosis (MTB). Presently several lines of evidence suggest that ICL from MTB (MTB-ICL) may play some roles in the interaction between MTB and host macrophage. However, there has been no research on the interaction between MTB-ICL and host macrophage.

METHODSMTB-icl and M. smegmatis (MS)-icl genes were amplified by polymerase chain reaction (PCR) and cloned into the E. coli-mycobacterium shuttle plasmid pUV15 to obtain recombinant shuttle plasmids pMTB-icl and pMS-icl. Following transformation into MS by electroporation, the expression of pMTB-icl and pMS-icl was verified by reverse transcriptase (RT)-PCR. The expression of recombinant plasmids derived from pUV15 when rMS was phagocytized by macrophage was also verified via fluorescence microscope. Ms 1 - 2c, rMS-pUV15, rMS-pMS-icl and rMS-pMTB-icl were used to infect RAW264.7 cells and the survival of intracellular MS was monitored by bacterial culture at 0, 24 and 48 hours after infection. The culture supernatants from macrophage infected by Ms 1 - 2c, rMS-pUV15, rMS-pMS-icl and rMS-pMTB-icl were collected and the interferon (IFN)-gamma and nitric oxide (NO) concentrations were measured by ELISA or by Griess assay, respectively. The apoptosis of macrophage was assayed by the in situ TUNEL technique.

RESULTSRT-PCR showed that both pMTB-icl and pMS-icl could be expressed in MS. Fluorescence microscopic observation showed that recombinant plasmids derived from pUV15 (pUV15-IG) could also be expressed in MS when MS were phagocytized by macrophage. Bacterial culture data demonstrated that rMS-pMTB-icl exhibited significantly increased intracellular survival in the murine macrophage cell line RAW264.7 compared with Ms 1 - 2c, rMS-pUV15 and rMS-pMS-icl. This increased intracellular survival was not accompanied by the upregulation of IFN-gamma and NO in host macrophage. But a lower apoptosis rate of macrophages infected with rMS-pMTB-icl was observed when compared with macrophages infected with other strains of MS.

CONCLUSIONSMTB-ICL could promote the intracellular survival of MS. Suppressing the apoptosis of host macrophage may be one of the important mechanisms involved in this increased intracellular survival.

OBJECTIVETo discuss the diagnosis and treatment of penile carcinoma in circumcised men.

METHODSWe reviewed 17 cases of penile carcinoma detected 1 month to 16 years after circumcision performed in our hospital from January, 1997 to December, 2004.

RESULTSOf the total number, 11 cases were diagnosed as penile carcinoma 1 - 12 months and the others 3 - 16 years after the circumcision. Sixteen of them were treated by partial penectomy, anti 1 first by extensive circumcision and later by partial and total penectomy successively after recurrence. Cloquet nodes biopsy showed 16 cases to be pathologically well-differentiated and I case moderately differentiated penile squamous carcinoma. One died of extensive metastasis, but the other 16 remained disease-free survivals.

CONCLUSIONCircumcised adult men, especially those over 40 years of age, are likely to develop penile carcinoma. Patients with inflammation, plaque or ulcer in the prepuce should be checked by pathological biopsy and followed up closely. For Stage-I penile squamous carcinoma, partial penectomy is shown to be an effective therapeutic option, and Cloquet's nodes biopsy is necessary for all patients.

OBJECTIVETo investigate the clinical features, pathology, diagnosis and treatment of inverted urothelial papilloma.

METHODSA total of 151 cases of urothelial inverted papilloma were analysed retrospectively. Of the cases, 134 were male and 17 were female, with a mean age of 54 years old. Most patients complained of painless gross hematuria. The diagnosis could be established mainly by ultrasonic, intravenous urography, retrograde pyelography, cystoscope and pathology. Among them, 7 cases who had the papilloma at upper urinary tract underwent nephroureterectomy except one. One hundred and forty-four cases had the papilloma at low urinary tract, with 124 treated by transurethral bladder tumor resection (TURBT), among which 11 cases accompanying benign prostatic hyperplasia were treated by transurethral prostatic resection, 3 by transurethral resection of prostatic urethral tumor, 15 by partial cystectomy, 2 by total cystectomy.

RESULTSOne hundred and eighteen cases were followed up 1 year to 12.5 years (mean 6.3 years). Intravesical recurrence was found in 5 cases. Of them 2 cases developed malignance in 8 and 30 months postoperatively, and 1 case underwent total cystectomy.

CONCLUSIONSInverted urothelial papilloma is a benign tumor, which appears male predominant. Most of the lesions are found in the bladder. TURBT is the preferred treatment choice for inverted papilloma of the bladder. Although this disease has a good prognosis, regular follow-up observations are necessary.
