This study aims to assess if adverse drug reactions (ADRs) to Kudiezi injection are allergic in origin. Hospital information system (HIS) data from 18 hospitals in China were used to carry out a nested case control design study. Included were patients who received dexamethasone for suspected allergic reactions after receiving Kudiezi injection. These were compared with non-allergic reaction people. Single factor logistic regression and multiple factor logistic regression were used to analyze data. Condition on admission, allergic history, dosage, disease status and drug combinations were taken into account in cases of suspected allergic reactions. After analysis in two subgroups we found that the condition on solvents had a significant effect, P values were 0.005 5 and < 0.000 1 on suspected cases of allergic reactions. For the first subgroup analysis, we found using other eight injections at the same time as Kudiezi injection could be risk factors in suspected cases of allergic reactions. For the second subgroup analysis combining using mannitol or fructose could increase risks. Based on this current research, condition on admission as well as the concomitant use of some other drugs may be the risk factors in suspected cases of allergic reactions. However, further research for verification is required. This study can provide guidance for safe clinical practice in using Kudiezi injection.

OBJECTIVETo retrospectively analyze the causes of death in elderly patients with hypertension in a hospital-based population from 1993 to 2012.

METHODSDuring the study period of over 19 years, a total of 2866 cases of death in 25238 hospitalized hypertensive patients with the age of 60 years or older were documented. Age, gender, complications, cause of death and other relevant variables were collected. All patients were divided into different subgroups according to gender, age or hypertension stage and risk stratification. The mortality of elderly hypertensive patients was analyzed using chi-square test.

RESULTS(1) Target organ damage (TOD) associated with hypertension was present in a substantial proportion of elderly patients. The complications related to death were heart disease (45.15%), stroke (34.37%), renal failure (11.88%), infective disease (4.58%), and cancer (4.06%). (2) Mortality in male elderly hypertension was higher than in women (53.31% vs 46.69%). The percentage of deaths from heart disease and stroke were higher in men than those in women (heart disease: 46.73% vs 43.35%; stroke: 37.04% vs 31.32%). (3) Age-specific constituent ratio of cause of death showed that deaths from stroke were significantly lower in very old patients (> or = 90 years) than in patients with 60-79 years of age (P < 0.01). In addition, deaths from heart disease, renal failure and infection disease were significantly lower in patients with more than 90 years than other patients. Deaths from cancer were highest in patients with 70-79 years of age (P < 0.01). (4) When compared with patients at stage 1 and 2 hypertension, subjects at stage 3 were more likely to die from stroke (P < 0.01) and renal failure (P < 0.05), while less likely to die from heart disease and cancer (P < 0.01). Patients in high and very high risk stratification of hypertension, compared with subjects in low and medium risk were likely to die from renal failure (P < 0.01) whereas less likely to die from heart disease (P < 0.05) and stroke (P < 0.01).

CONCLUSIONPrevalence of complication and TOD is high in elderly hypertensive inpatients, especially in deaths. The male patients and 60- 79-year-old patients have a higher percentage of causes of death. The stage and risk stratification of hypertension are associated with constituent ratios of the causes of death.

ObjectiveTo construct ompW- and ompW+ mutants of Salmonella paratyphi A with λRed system,and then study the function of the gene preliminarily.Methods Homologous regions were amplified from the genome Salmonella paratyphi A 50973,and then connect with kana fragment from plasmid pET22b-kan to construct a recombinant vector.The resultant fragments were amplified and transferred into 50973 with the help of λRed system after its concentration.Then the ompW- mutant was obtained PCR identification.Connect the recombinase expression plasmid pACU184 with full fragment of ompW regulatory region and coding region,then transfer the connection product into the mutant,the ompW+ mutant was obtained after double digest identification.Full cells of the wild,ompW- and ompW+ mutants were samples for SDS-PAGE and Western blot to detect the expression of protein OmpW.Biochemical identification of wild strain and mutant strains was conducted,so did the growth curves of the wild and the ompW- mutant.Choose BALB/c mice as a model to determine median lethal dose LD50 of the wild and mutant strains in order to observe the correlation between ompW gene and bacterial virulence.ResultsompW gene was knocked out in Salmonella paratyphi A 50973,also the ompW+ mutant was constructed; The wild and ompW+ mutant express the protein OmpW,while the ompW- mutant lost the protein.Each of the wild and mutant strains was Salmonella paratyphi A,and no obvious difference could be observed for their growth curves.LD50 for each strain was also similar.Conclusion The ompW gene has no correlation with the virulence in S.paratyphi A 50973,but the contribution of the mutants made an important foundation for the further study of functions of the gene ompW in Salmonella paratyphi.

Objective To evaluate systematically whether administration of hypertonic saline transfusion affects clinical outcomes with compared to standard fluid in the early stage of resuscitation for traumatic shock patients.Methods Seven English and Chinese routine biology and medicine databases were searched for randomized controlled trials (RCTs) published from January 2002 to August 2012,and established inclusion and exclusion criteria to evaluate these RCTs.The quality assessment was based on the Cochrane Handbook for Systematic Reviews of Interventions Version 5.0.1 and Jadad' s score scale.RevMan 5.0 statistical software was used for meta-analysis.Results After evaluated 211 related literatures,five RCTs met all the inclusion criteria and were enrolled for meta-analysis.The meta-a nalysis demonstrated that early hypertonic transfusion did not decrease short-term (first 48 hours after admission) mortality (RR =1.04,P =0.74); nor did it decrease later-term (7day to 3month after injury) mortality (RR =0.97,P =0.72).It also did not decrease the total volume of fluid and blood transfusion required during the first day (P =0.38).Similarly,it did not affect the incidents of infections (RR =1.04,P =0.70),the length of stay in ICU (P =0.2) and total length of stay in the hospital.Conclusions Compared to standard fluid,there was no advantage on mortality and hospital infection by using hypertonic supplement transfusion in the early stage of resuscitation for traumatic shock patients.Hypertonic transfusion did not have any significant effect on the volume of total fluid and blood transfusion required the first day,and no trend of reduction for the length of ICU and hospital stay.Further well-designed randomized controlled trials are needed to demonstrate the cost effectiveness of hypertonic transfusion to traumatic shock patients while in ICU.

OBJECTIVETo explore clinical significance of rotational axis of distal femur on Chinese adults in total knee arthroplasty (TKA).

METHODSThere were 86 Chinese adults (106 normal knees) including 47 males (53 knees) and 39 females (53 knees), 54 knees were on left and 52 on right. The CT scan was employed in the distal femur. The scan direction was aligned to be on the plane perpendicular to the mechanical axis of the femoral. The CT images of cross sections across lateral and medial femoral epicondyle were moved to personal computer,lateral angle between anterior posterior line (APL) and surgical transepicondylar axis (STEA) (ATA),lateral angle between posterior condylar line (PCL) and APL (APA), angle between perpendicularity of APL and PCL (A-PA), posterior condylar angle (PCA), condylar twist angle (CTA), angle between clinical transepicondylar axis (CTEA) and STEA (CSA) were measured. These values were divided into different groups according to gender and side, the values of CTA, PCA, A-PA, angle PT (varus of tibia plateau), constant 3, ATA, APA and constant 90° were compared by statistically. A-PA and PCA, and CTA were analysed statistically with the liner regression, the relationship among CTEA, STEA ,PCL, APL and PLP were performed to assess by liner regression.

RESULTSATA was (89.79 ± 1.22)°, APA was (84.84 ± 1.83)°, A-PA was (5.16 ± 1.83)°, PCA was (4.80 ± 1.23)°, CTA was (8.23 ± 1.40), CSA was (3.45 ± 0.68)°. All the parameters had no differences on sex and side,but CSA had difference on male and female. There was no difference among angle PT, PCA, A-PA. There was significant difference in CAT, constant 30 and angle PT, PCA,A-PA. There was no difference between ATA and constant 90°, but there was difference between APA and constant 90°. There was relativity between PCA and CTA, and also PCA and A-PA, CTA and A-PA. There was significant relativity between STEA and CTEA, between STEA and APL, between STEA and PCL, and also between APLP, APL and PCL, but there was no significant relativity between PCL and CTEA.

CONCLUSIONTKA for Chinese, the section of femoral posterior condyle should be external 5° to obtain the optimum rotational orientation. The property is different entirely between STEA and CTEA, the rotational alignment is not performed according to parallel to the CTEA in distal femur. Among STEA, APL, PCL, the STEA is the most reliable mark ofrotational alignment of the distal femur, and the PCL is the less reliable mark.

Objective To summarize the effect of en bloc kidney transplantation (EBKT) from cardiac deceased infant donors into adult recipients and to share a new simplified EBKT technique.Methods Fourteen dual kidneys from infant donors (9 males,and 5 females) were transplanted into adult recipients (3 males,and 11 females).The donor ages ranged from 17 days to 8 months,and the recipient ages ranged from 19 years to 61 years.The recipients were categorized into 2 groups in terms of the microvascular surgical techniques.Case 1 to case 9 was given traditional techniques and case 10 to case 14 simplified techniques.In detail,the dual kidneys were recovered en bloc with the aorta and inferior vena cava.After splitting the rear wall of the donor aorta and inferior vena cava,suitable size of patches were made by cutting along the vascular openings of renal arteries and renal veins.We anastomosed the aorta patch to the external iliac artery in an end-to-side fashion.The donor inferior vena cava patch was anastomosed to the external iliac vein in an end-to-side fashion.The distal ends of ureters were implanted into the bladder separately.Results In traditional group,two cases underwent peri-operative graft loss because of renal artery thrombosis,and one patient died of pneumonia 16 days post-operation.During the follow-up period,graft loss was seen in 2 patients caused by irreversible drug-induced nephrotoxicity and donor-derived malignant tumor respectively.The mean serum creatinine level was 81.7 ± 27.4 μmol/L and eGFR level was 82.5 ± 22.2 mL/min/1.73 m2 in the other EBKT recipients at 24th week post-operation.In simplified group,no vascular complications post-operation occurred.Conclusion En bloc infant kidneys could be transplanted into adult recipients successfully with excellent graft function and survival outcome while censored perioperative patient death and surgical failure.Instead of traditional EBKT technique,simplified EBKT technique could decrease the incidence of surgical vascular complications and should be applied to more recipients.

Through review of the major databases in English and Chinese, it is found that there is an absence of articles on special coverage of compliance of research fellows and testees in acupuncture clinical trials. Therefore, the author proposed (1) The compliance of research fellows should be guaranteed through proper work division with reasonable, standard and strict research designation as well as comprehensive systems of selection, supervision and estimation. (2) The compliance of testees should be guaranteed through enhancing of the right to know, improving of the medical environment and constructing a better doctor-patient relationship. Therefore, the compliance of clinical trials can be improved, the quality of clinical research enhanced and the reliability of the research results can be guaranteed.

Objective To investigate the efficacy and safety of domestic oseltamivir in patients with influenza. Methods A randomized, single-blinded, controlled clinical trial was performed.Patients in the study group received domestic oseltamivir, while the patients in control group received foreign oseltamivir. The doses were both 75 mg every time, twice a day. The treatment durations in both groups were 5 days. Chi square test was performed to compare baseline characteristics and the difference of side effects. Paired t test was used to compare the efficacy. Results Two hundred and nine patients were enrolled in this study (98 cases in study group. 111 cases in control group). The trend in body temperature change was similar in the two groups (t = 0. 061, P>0. 05). The score of symptom severity decreased more quickly in patients treated with foreign oseltamivir compared to those treated with domestic oseltamivir during the period from 24 h to 48 h. However, the difference between the two groups diminished gradually and was not statistically significant at 72 h (t=0. 875,P>0. 05). The safety of the domestic and foreign oseltamivir were comparable(X2 = 0. 197,P>0. 05). Conclusion The domestic oseltamivir is as effective and safe as the foreign oseltamivir.
