The bile was collected from fro patients with biliary infections, with the bacterium isolated to study the sensitivity of each kind of the bacterium to several antibiotics in common use. Except G- bacterium, we also found some kinds of G+ bacterium in infection bile. G- bacterium were not sensitive to Clindamycin, G+ bacterium were sensitive to Ciprofloxacin. Escherichia coli, Xanthomonas maltophilia, Enterobacter cloacae, Pseudomonas aeruginosa were sensitive to Ampicillin. G+ bacterium were not sensitive to Azactam. Enterococcus faecalis, Enterococcus faecium, Enterobacter cloacae were not sensitive to Ceftazidime. Enterococcus faecalis, Staphylococcus coagulase negative, Staphylococcus epidermidis, Pseudomonas aeruginosa were not sensitive to Ceftriaxone Sodium. We didn't found any bacterium resistance Imipenem. The possibility of the existence of G+ bacterium as well as drug resistance should be considered n patients with biliary infections. The value of susceptibility test should be respected to avoid drug abuse of antibiotics.

Objective To identify and investigate B(A)02 allele in a patient. Methods Serological tests were performed with standard serological methods in a patient with B(A)02 allele. DNA sequences of all seven exons and exon-intron boundaries of ABO gene were analyzed by polymerase chain reaction (PCR), direct DNA sequencing and sequencing after gene cloning. In order to analyze the allele, PyMOL software was used to establish 3D model of Glycosyltransferases B (GTB). Results The serological results showed the characteristics of B(A) phenotype. DNA analysis revealed that ABO gene of the individual was heterozygous of B(A)02/O01 allele. 700C>G mutation was identified in B101 allele, which resulted in the amino acid substitution P234A in GTB. Through the analysis of the 3D structure of GTB, it was speculated that the P234A replacement affected the intermolecular forces of the 234 amino acid and Met-266, thus changed the conformation of the donor-binding pocket of GTB,that made GTB capable of recognizing and tranferring the GalNac to the H antigen, which can lead to the formation of the weak A antigen on membrane of red blood cells. Conclusion The P234A replacement can affect the spatial conformation of the specific recognition region conformed by Met-266 and Ala-268 residues, which leads to the antigenicity change of the ABO blood group.

To study the chemical constituents of Nervilia fordii (Hance) Schltr., various chromatographic methods were used, including D101 macroporous resin, silica gel, ODS and preparative HPLC chromatographic techniques. A new labdane diterpenoid glycoside named as nervilifordoside A was isolated from 60% EtOH extract of Nerviliafordii. The structure of compound 1 was elucidated as 12, 17-epoxy-3-hydroxy-17-methoxy-labdan-13-en-16, 15-olide 3-O-alpha-rhamnopyranosyl-(1 --> 2)-O-beta-glucopyranoside on the basis of HR-MS, 1D and 2D NMR spectroscopic data as well as chemical methods.

Objective To investigate the expression and significance of human TREM-1 mRNA in patients with (biliary) infection. Methods Peripheral blood of 32 patients with biliary infection and 7 healthy volunteers were (collected). TREM-1 mRNA was determined by semi-quantitative RT-PCR. TNF-? was determined by ELISA method. Results The values of TREM-1/?-actin of control group was 0.48?0.072, while those of biliary infection group in 1d, 2d, 3d, 7d were 0.93?0.070,0.90?0.060,0.82?0.092,0.66?0.062 respectively (P

Objective To study the intervention effectiveness of intensive training in medical interns’occupational exposure protection.Methods Medical interns in seven colleges and universities in Wuhan between 2011 and 2015 were chosen and divided into control group (675 medical interns in 2011 - 2013,comprehensive training about healthcare-associated infection control was conducted for once before internship )and intervention group (682 medical interns in 2014 - 2015,hospital-department-tutor three steps of intensive training was conducted),the occurrence of occupational exposure and exposure knowledge awareness between two groups were compared. Results The awareness rate of knowledge about occupational exposure protection and the implementation rate of protective measures in intervention group were both higher than control group (all P <0.05).Incidence of occupa-tional exposure in intervention group was lower than control group (21 .70%[n=148]vs 65.33%[n=441 ],χ2 =262.91 ,P <0.01);percentage of interns who conducted active serological virus detection and intensified vaccination of hepatitis B virus were both higher than control group (14.66%[n=100]vs 2.96%[n=20];11 .73%[n=80]vs 2.67%[n=18],respectively).Occupational exposure before and after intervention occurred most frequently when interns were preparing medicine,occupational exposure reporting rate in intervention group was higher than control group (72.97%[108/148]vs 50.11 % [221/441 ],χ2 =52.78,P <0.01 ).Conclusion The intensive training of occupational exposure protection among medical interns can improve the awareness and skills of occupational protec-tion,and reduce the occurrence of occupational exposure.

Objective To compare efficacy of female sterilization by modified Uchida technique and silver clips and to evaluate the influence on operation procedure and clinical effect with or without surgery training of service providers. Methods A comparative, multicenter clinical trial was performed in 18 county and township-level service centers. Totally 2198 women underwent sterilization from these 18 study center were divided into 1116 women sterilized by modified Uchida technique and 1082 women by silver clips.Those 18 centers were classified into 9 training groups which provide surgical skills of sterilization and other contents and 9 non training groups. Clinical documents of sterilization were recorded. All women were followup at 3, 6 and 12 months after surgery. Results There were no complications during surgery by both sterilization. The failure rate was 2.03% (22/1082) in silver clip method and the mean operative time were ( 12. 4 ± 6. 4 ) minutes in training group and ( 14. 4 ± 8. 1 ) minutes in non training group. In modified Uchida method, the failure rate was 0. 18% (2/1116) and the mean operative time were (16. 2 ± 4. 9)minutes in training group and (19.0 ±8.6) minutes in non training group. The mean operative time between two groups reached statistical difference ( all P ＜ 0. 05 ). Total ended rate in modified Uchida technique were 2. 2/hundred women year in training group and 2. 5/hundred women year in non training group, and the rate of silver slips were 3. 9/hundred women year and 4. 8/hundred women year, which did not show significant difference ( all P ＞ 0. 05 ). There was no significant difference in acceptability and side effects of all women between two methods (P ＞ 0. 05). The training of service providers could influence acceptability of women (P ＜ 0. 05). Conclusions Clinical efficacy was not influenced by those two methods. The operative time and acceptability were improved by training surgeons in silver clips method.

ObjectiveTo explore the effect of osteoclasts and osteoprotegerin/receptor activator of nuclear factor-kappa B ligand (OPG/RANKL) system on bone destruction of psoriatic arthritis.MethodsThe peripheral blood mononuclear cells from 41 psoriatic arthritis (PsA) patients,20 osteoarthritis (OA) patients and 24 healthy controls were cultured to become osteoclasts.After 14 days,cytochemistry method was used to detect tartrate-resistant acid phosphatase (TRAP) expression.At the same time,enzyme-linked immuno sorbent assay(ELISA) was used to measure the levels of serum OPG and RNAKL for all cases.At the same time,the clinical and laboratory examinations of the PsA were collected.Statistical analysis was conducted with one-way ANOVA and Spearman's correlation.ResultsSignificantly higher OC production was observed in the peripheral blood of PsA patients[(17.7±4.8)/view field] than that of the healthy controls[(6.4±1.6)/view field] and OA patients [(6.5±l.6)/view field].The levels of RANKL were significantly higher in PsA patients [(178±38) pg/ml] than those in the other two groups [(32±4) pg/ml and (67±17) pg/ml].There was significant difference between the PsA group with bone destruction and without destruction in the levels of OC and RANKL [(17.6±0.9) /view vs(7.9±1.3) /view and(199±72) pg/ml vs(128±44) pg/ml,P＜0.01].Imaging scores was positively correlated with the levels of OC and RANKL in PsA patients (P＜0.05).ConclusionIn PsA,there are significantly more OC and higher RANKL in the peripheral blood than those of the controls.The high levels of OC and RANKL are closely related with bone destruction.OC and RANKL are useful in identifying bone destruction.

Objective To review the efficacy of bisphosphonates in reducing skeletal events in patients with multiple myeloma. Methods Two hundred and five patients with newly diagnosed MM were enrolled in this retrospective study,with bisphosphonates or not.Skeletal-related events,therapeutic reaction of myeloma bone disease and patient survival were analyzed. Results The occurrence of skeletal-related events (SRE) per patient year (P＜0.01) and the time to first SRE (P＜0.05)were significantly lower in the reatment group than in the untreated group. After 6 cycles of treatment, a significant higher percentage of effective and marked effect patients were observed through X ray in the treatment group (80.0 ％) compared to the untreated group (48.7 ％), P＜0.001. There was no overall significant difference in the level of serum calcium between the two groups (P=0.278). After 6 cycles of treatment, the patients who received bisphosphonates had significant decreases in bone pain and lower ECOG score (ECOG≤2) compared to the untreated group (P＜0.05). Bisphosphonates were tolerated well, and the common adverse reaction including gastrointestinal reaction (3 cases,3.3 ％),fever (lcase,1.1％) and skin rash (2 cases,2.2 ％).There was no significant difference in overall survival between the two treatment groups,(P=0.580).Conclusion Infusions of Bisphosphonates could reduce the occurrence of skeletal- related events (SRE), prolong the time to first SRE and improve the quality of life of patients with multiple myeloma. Bisphosphonates could not prolong survival time of myeloma patients.

Objective To investigate the difference of clinical characteristics and outcomes between different isoforms of BCR/ABL in adults with Philadelphia-positive acute lymphoblastic leukemia (ALL).Methods The data of 106 adults with Ph+ALL diagnosed in our hospital from January 1, 1996 to December 31, 2007 were reviewed. The difference of clinical characteristics between different subgroups of BCR/ABL was compared and their relation with outcomes was studied. Results The median age of the 106 patients was 34 years and the median white blood cell count at baseline was 28. 5 × 109/L. Comparative analysis demonstrated that patients in p210 group had an older age, higher blood platelet count (BPC) and more frequent occurrence of splenomegaly. Referring to the outcomes, the complete remission (CR) rate of the two groups were 92. 2% and 93.9%, respectively. The median overall survival (OS) and relapse free survival (RFS) in p190 group were 13 months and 10 months, the 1,3-year estimated OS were (54. 7±6. 7)% and (5.5±5.2)%, and the 1,3-year estimated RFS were (40. 2±6. 8)% and (7. 8±6. 7)%,while in p210 group, the median OS and RFS were 15 months and 10 months, respectively, the 1,3-year estimated OS were (65.8±8. 9)% and (14. 5±7.4)%, and the 1,3-year estimated RFS were (48. 3±9. 4)% and (12. 9±7. 7)%. All of the above data had no statistic significance between the two groups.Conclusion Majority of the adults with Ph+ALL is p190 positive and patients with p210 have older age, higher BPC and more frequent occurrence of splenomegaly, while there is no significant difference between p190 group and p210 group in CR rate, RFS and OS.
