Objective To know the expression of 47 kD protein of orientia tsutsugamushi(Ot) Karp strain and test its immunogenicity and antigenicity.Methods Forty-seven kD protein gene that code the whole mat peptide was amplified from the genomic DNA of Ot.Karp strain by PCR and constructed to a recombinant plasmid pGEX-47.The E. coli cells BL21 were transformed with pGEX-47,then the transformants were induced to express the recombinant 47 kD protein by IPTG. The antigenicity and immunogeni-(city) were identified by Dot Blot method and the experiment of immunizing mice respectively.Results 1. The PCR product of 47 kD protein gene of Ot.Karp strain was obtained and its sequence was the same as the published 47 kD protein gene.2. The E.coli expression plasmid pGEX-47 constructed was identified containing the 47 kD protein gene fragment by restrication analysis and PCR identification,and an expression band about 47 kD was detected by SDS-PAGE of the purified product from GST-fusson protein expressed by pGEX-47. 3.Dot Blot analysis and the experiment of immunizing mice testified its antigenicity and immunogenicity.Conclusions The 47 kD protein gene of Ot Karp strain is amplified that code the whole mat peptide, which can be expressed in prokaryotic cells and the expressed protein has antigenicity and immunogenicity.

OBJECTIVE To compare the bacterial resistance of wounds and clinical features in burned patients in intensive care unit (ICU) with those in general wards (GW) in the same period so as to provide basis for clinical prevention and treatment. METHODS Nineteen cases with wound infection admitted to the burn unit during June and July in 2005 were included in the retrospective study, 4 cases with 114 bacterial strains were from ICU and 15 cases with 47 bacterial strains were from GW respectively. The clinical features, bacterial culture and sensitivity test to antibiotics were analyzed. RESULTS Susceptibility to bacterial infection in ICU patients was significant than those in GW. The prevalent bacterial strains in ICU were Pseudomonas aeruginosa (PAE), Staphylococcus aureus (SAU) and Acinetobacter baumannii (ABA). In contrast, SAU, ABA, Klebsiella pneumoniae (KPN) and PAE prevailed in GW. Drug resistance of PAE, ABA and KPN to some kinds of antibiotics in ICU was severer than those in GW. CONCLUSIONS There is relatively great difference in bacterial constitution and drug resistance ratio between ICU and GW. To take certain disinfection and isolation measures could effectively prevent bacterial strains from transmitting among the wards.

Proteins extracted from two varieties of Chinese roses leaves were separated by two- dimensional polyacrylamide gel electrophoresis (2-DE) with immobilized pH gradient (IPG). Many difference proteins were isolated with molecular weights ranging 10-30 kDa and pI5-6. Three proteins of high levels observed in a gel were excised and identified using peptide mass fingerprinting and MS-MS. A summary of the identified proteins and their putative functions are presented. They are identified as eIF-5A、LEA protein and Hsp17. 5. Functions of these proteins in plant tolerance to high temperature were discussed.

Objective To assess the incidence and prognosis of the bronchial anastomosis complications following lung transplantation.Methods Between January 2003 and July 2016,all 81 cases after lung transplantation at Department of Thoracic Surgery of Shanghai Pulmonary Hospital,Tongji University were retrospectively analyzed.We analyzed the incidence and prognosis of postoperative complications of bronchial anastomosis in lung transplant recipients.Results The overall incidence of bronchial anastomotic complications was 30.9％,including anastomotic infection (18.5 ％),anastomotic fistula (4.9 ％),stenosis (6.2 ％),and bronchomalacia (1.2 ％).One case died of infection,and 3 cases died of anastomotic fistula.Conclusion The main bronchial anastomosis complications occurred early,and the prognosis was acceptable.

AIMTo compare the TAOC of quercetin, rutin, vitamin C, vitamin E in vitro and examine the effect of quercetin on TAOC of rat plasma after intragastric administration.

METHODSFe3+ reducing ability assay, UV spectrum analysis and HPLC analysis were used to measure TAOC of plasma and the contents of quercetin and rutin after intragastric administration.

RESULTSThe TAOC of quercetin was stronger than that of rutin and roughly equal to vitamin C and vitamin E in vitro. After intragastric administration of quercetin (40 mg/kg bw), the TAOC and content of quercetin in rat plasma increased significantly. Vitamin C also increased plasma TAOC significantly, but rutin and vitamin E didn't after intragastric administration. However, there was no remarkable absorption peak of quercetin on HPLC chromatograms and on the other hand, the peak areas of two unknown peaks near quercetin peak were increased after intragastric administration of quercetin.

CONCLUSIONThe antioxidant capacity of quercetin was stronger than rutin and comparable to vitamin C both in vitro and in vivo. After absorption, quercetin is metabolized to its derivatives.

OBJECTIVETo evaluate the applicability of immune-related response criteria (irRC) in treating non-small cell lung cancer (NSCLC) by Chinese medicine (CM).

METHODSTotally 97 stage III a-IV NSCLC patients were predominantly treated with comprehensive CM. Curative effects were evaluated by three methods such as Response Evaluation Criteria in Solid Tumors (RECIST), Oncologic Curative Effect Evaluation Criteria of Chinese Medicine in Solid Tumor (draft, abbreviated as CM criteria), and irRC. The correspondency and consistency between irRC, RECIST and CM criteria were analyzed and compared. The objectivity of irRC in evaluating curative effect of Chinese medical treatment for NSCLC was assessed.

RESULTSThe correspondency rate of irRC to RECIST was 59. 79% with Kappa value of 0. 379 (U test, P <0. 01). The two criteria had certain correspondence, but with an unsatisfactory consistency. The correspondency rate of irRC to CM criteria rate was 83. 51% with Kappa value of 0.751 (U test, P <0. 01). The two criteria had good correspondence and consistency.

CONCLUSIONSCM criteria had good consistency with CM criteria in evaluating curative effect for Chinese medical treatment of advanced NSCLC. Its results could objectively reflect features and advantages of CM for treating advanced NSCLC.

OBJECTIVETo explore methods and clinical effects of composite external fixtor in treating adult patients with unstable middle 1/3 of clavicular fractures.

METHODSFrom March 2008 to March 2011,36 patients with unstable middle 1/3 of clavicular fractures were treated with composite external fixtor. There were 24 males and 12 females, aged from 18 to 55 years old with an average of 43 years old. Twenty cases on the left side and 16 cases on the right side. Time from injury to operation was 2 to 6 days (averaged 3.5 days). According to Robinson classification, there were 7 cases with type 2A2, 18 cases with type 2B1, and 11 cases with type 2B2. No vessels and nerve damage occurred before opreation. The clinical effects were evaluated according to Neer scoring.

RESULTSAll cases were followed up from 6 to 12 months with an average of 8 months. The mean Neer score was 88.3 +/- 6.2, which included pain 31.6 +/- 3.2, functional score 25.7 +/- 2.2, range of motion score 21.1 +/- 1.7, and anatomy score 8.8 +/- 0.8. There were 22 cases in excellent, good in 13, fair in 1. Two cases occurred pin tract infection.

CONCLUSIONComposite external fixtor is an optional method in treating unstable middle 1/3 of clavicular fracture, and can obtain a good clinical effects.

Objective To study the efficacy and toxicity of gensenoside-Rg3 (Rg3) combined with radiotherapy on non-small cell lung cancer ( NSCLC ) at advanced stages (Ⅲ and Ⅴ ).Methods Sixty-three patients with stage Ⅲ or Ⅳ NSCLC were divided randomly into two groups:treatment group ( n =35 ) treated with Rg3 combined with radiotherapy and control group ( n =28 ) treated with radiotherapy alone.The efficacy and side effects were compared after the treatment.Results The response rate ( CR + PR) of the treatment group was 57.14％,significantly higher than that of the control group (32.14％,x2 =3.91,P ＜ 0.05).The median survival time of the treatment group was 14.2 months,significantly longer than that of the control group ( 11.2 months,x2 =2.07,P ＜ 0.05 ).The one-year survival rate of the treatment group was 62.86％,significantly higher than that of the control group (39.29％,x2 =4.40,P ＜0.05).The incidence rates of side effects of the treatment group were all lower than those of the control group,but there were not significant difference. Conclusions Gensenoside-Rg3 combined with radiotherapy is effective for advanced stage NSCLC,with attenuation and synergistic effects.
