The short-term and long-term effects were compared in the three groups. [Results] Total effective rate was 98.3% in group A, 88.0% in group B and 74.0% in group C ( P

OBJECTIVE: To study the situation and the related factors of ADR occurred in our hospital and to provide references for rational use of drug. METHODS: A total of 246 ADR case reports collected in our hospital from Nov. 2007 to Oct. 2008 were analyzed statistically. RESULTS: Of the 246 ADR cases, 120 kinds of drugs were involved. 64.63% of ADR were induced by intravenous drip infusion; 42.28% were antimicrobial,13.01% were drugs for central nervous system, 10.57% were for circulation system, 7.32% were TCM preparation; ADR-inducing TCM injection accounted for 50.00% in TCM preparations. The main clinical manifestation represented as lesion of skin and its appendants (51.63%). 11 severe cases accounted for 4.47% and 1 new cases only 0.41%. CONCLUSION: ADR may be caused by many factors. The most attention should be paid to monitoring ADR in the clinic so as reduce or avoid occurrence of ADR.

Objective To correlate vWF expression in the endothelium of transitional pulmonary arterioles from lung biopsy in patients with pulmonary hypertension (PH) secondary to left-to-right shunt congenital heart defects (CHD). The results will be compared to vWF expression in peripheral venous plasma pre-operatively and the early post-operative outcome. Methods Consecutive 70 cases of left-to-right shunt congenital heart defects were involved in the study, the age ranged from 4 months to 63 years. Pulmonary systolic pressure/systemic systolic pressure (Pp/Ps) was calculated from Swan-Ganz floating catheter monitoring before corrective operation. PH was found in 62 cases, with slight PH in 16, moderated PH in 24 and severe PH in 22. Non-PH in 8 cases. Twenty-six cases of non-heart and lung disease were involved in as control. Lung biopsy tissue was stained for routine pathologic classification and quantitative vWF expression, with testing vWF in the peripheral venous blood. Post-operative complication was noted. Results There was a statistically difference of vWF expression in the endothelium of pulmonary transitional arterioles between PH group and non-PH group, with reducing intensity in order of non-PH, slight Ph, moderate PH and severe PH. A negative relationship was statistically noted between Pp/Ps and vWF expression in the arteriole endothelium (=61.88-33.30x, r=-0.701, P

Objective To evaluate regenerative nerve and functional recovery of target muscle in rats with sciatic nerve defect bridged by acellular nerve allograft made through chemical extraction.Methods Sciatic nerve of SD rats was processed in a volume fraction of 3％ Triton X-lO0 solution and 40 g/L sodium deoxycholate solution.Morphology of myelin sheath,axons and basal lamina tubes of sciatic nerve segments was observed under the light microscopy before and after the chemical processing.Twenty-five Wistar rats were divided into acellular nerve allograft group (n =10),autograft group (n =10) and normal control group(n =5) according to the random number table.A 1 cm sciatic nerve defect was created in acellular nerve allograft group and autograft group,and was respectively bridged by acellular nerve allograft and autograft.Sciatic nerve function index (SFI) was measured every two weeks.Twelve weeks after surgery,nerve conduction velocity (NCV),recovery rate of compound muscle action potential (CMAP) and recovery rate of muscle force were measured in each group.Results Cellular components including myelin sheath and axons were removed thoroughly,but the basal lamina tubes were preserved completely.At postoperative 2,4,6,8,10 and 12 weeks,SFI in normal control group (-1.7±5.9,-0.3 ±2.5,0.8 ±4.1,-1.4±3.6,-2.5 ±5.7 and-2.1±3.2) was superior over autograft group (-94.3±3.7,-90.1±4.1,-63.7±7.8,-51.9±8.2,-48.8±8.6 and -44.3 ± 10.5) and acellular nerve allograft group (-97.1 ± 5.3,-91.2 ± 6.1,-70.6 ± 5.5,-60.4±6.2,-58.2 ±10.2 and-56.4 ±8.0) (P ＜0.01).At postoperative 6,8,10 and 12 weeks,SFI in autograft group were better than those in acellular nerve allograft group (P ＜0.05).NCV [(61.6 ± 8.1) m/s],recovery rate of CMAP[(98.7 ± 5.9) ％] and recovery rate of muscle force [(101.8 ± 6.6) ％] in normal control group were higher than those in acellular nerve allograft group [(22.3 ± 4.7) m/s,(40.3 ± 9.2) ％ and (43.8 ± 9.3) ％] and those in autograft group [(29.0 ±5.5) m/s,(52.5 ± 10.6) ％ and (54.3 ± 10.5) ％] (P ＜ 0.01).NCV,recovery rate of CMAP and recovery rate of muscle force in autograft group were better than those in acellular nerve allograft group (P ＜ 0.05).Conclusions Acellular nerve segments are harvested satisfactorily by chemical extraction.Sciatic nerve defect in rats can be cured with the acellular nerve allograft,but the repair effect of autograft is relatively better.

Objective:To analyze the level and related factors of burden of care,quality of life in family members of patients with schizophrenia.Methods:Totally 312 family members of patients with schizophrenia in 5 blocks of Jing'an District,Shanghai,who consented the investigation,were investigated.Burden of care were evaluated with the Zarit Caregiver Burden Interview (ZBI),and quality of life of the relatives by World Health Organization Quality of Life BREF (WHOQOL-BREF) and Chinese Residents SWB abridged (SWBS-CC20).ZBI score equal or higher than 39 indicated a heavy burden of care,while the score less than 39 indicated a low burden of care.Results:Totally 199 cases (63.8％) were in a heavy burden,whose ZBI score was (52.1 ± 10.8),and 113 cases (36.2％) were in a low burden with a mean score of (23.1 ± 10.4).Their WHOQOL-BREF score and SWBS-CC20 score were lower than normal model (Ps ＜ 0.001).The burden was heavy to those whose spouse was involved (β =-7.76).Patient's age was negatively correlated with quality of life (β3 =-0.18).Relationship with the patient,education level and monthly family income were positively correlated with quality of life (β =1.65,1.68,1.66).Conclusion:Those families of patients with schizophrenia,who are aged,low educated,low paid,or whose spouse have been diagnosed with schizophrenia,may have a heavy burden of care,and low quality of life.

Objective To study the correlation between the mental health of family members of patients with schizophrenia and their coping style. Methods From December, 2014 to January, 2015, a total of 312 family members of patients with schizophrenia in 5 blocks were included. They were surveyed with self-made questionnaire, Self-rating Depression Scale (SDS), Self-rating Anxiety Scale (SAS) and Simplified Coping Style Questionnaire. The results were compared with the national normal model, and the correlation between SDS, SAS and the coping style was also analyzed. Results Compared with the normal model, the SDS (t=34.39, P<0.001), SAS (t=73.09, P<0.001) scores were higher in schizophrenia families, and they used positive coping style (n=128, 41%) less (t=-16.70, P<0.001), and more often used negative coping style (n=184, 59%) (t=-66.24, P<0.001). The SDS (r=-0.14, P<0.05), SAS (r=-0.15, P=0.01) scores were negatively correlated with positive coping style, the SAS score was positively correlated with negative coping style (r=0.27, P<0.001). Multivariate Lo-gistic regression analysis showed that women were prone to be anxiety and depressed compared with men (P<0.05); the divorcees were prone to be depressed compared with thoses not divorced. Education level and average monthly household income were factors influencing their coping style (P<0.05). Conclusion The mental health of family members of patients with schizophrenia is not optimistic, the female family members are more likely to be depressed and anxious than males. People with low education level and poor economic conditions more often use negative coping style, which need to be focused on, and to take appropriate and effective intervention.

BACKGROUND: Tendon injury is common in clinic, which is mainly treated by surgical anastomosis. Postoperative tendon healing is usually assessed through surgeons' experience due to high cost and application restrictions of MRI examination. Thus there is still a lack of a convenient and objective imaging support. With the advancement and widespread application of high-frequency ultrasound, the diagnosis rate of tendon injury has been improved remarkably; thereafter, high-frequency ultrasound used for assessing tendon injury and repair has become an issuehas become an issue of concern.OBJECTIVE: To clarify the ultrasonic imaging features of tendon repair through high-frequency ultrasound scancombined with histological examination.METHODS: This was a single-central, preoperative and self-controlled animal experiment and finished in the Central People'sHospital of Siping, China. 130 adult male Highbrow chickens were selected and were then randomized into 13 groups (n=10per group). One side of each chicken hind foot was randomly selected as experimental limb to undergo achillotomy followedby repair using the modified Kessler method (groups 2-13) or no treatment (group 1); the contralateral limb served as control.Moreover, passive flexion-extension functional training targeting the experimental limbs was performed in the groups 8-13beginning at the 1st day after surgical anastomosis, several times a day. The high-frequency ultrasound and hematoxylineosinstaining were conducted before and after chillotomy (group 1), and at 3 (groups 2 and 8), 7 (groups 3 and 9), 14 (groups4 and 10), 21 (groups 5 and 11), 35 (groups 6 and 12) and 42 (groups 7 and 13) days after surgical anastomosis, respectively.RESULTS AND CONCLUSION: The primary measurement outcomes were the repair and healing of the injured tendonas assessed by high-frequency ultrasound; the secondary outcomes were the pathological manifestations of the injuredtendon detected by hematoxylin-eosin staining. Our findings will provide preclinical proof for high-frequency ultrasounduse in the assessment of tendon injury, repair and healing as well as for the rehabilitation therapy that promotes functionrecovery in the future.

Objective To confirm the safety and nutritional efficacy of high branched-chain amino acids through a pragmatic study allowing its use as an alternative to 15AA in patients with liver dysfunction. Methods The study was performed as a randomized, prospective trial. Eighty two patients with liver dysfunction undergoing operation were randomly assigned to receive high branchedchain amino acids or 15AA as part of their TPN regimens for 7 days. Daily parenteral intakes of energy nitrogen and lipid were equal in the two groups. Results Efficacy analysis showed that high branched-chain amino acids were as efficient as 15AA in avoiding protein catablosim. No serious adverse event was reported in the two groups. For hematology, renal, hepatic safety criteria and for the vital signs,no significant difference was observed between the 2 groups. No significant difference was observed concerning nitrogen balance and protein catablosim. For peripheral immunoglobulin and lymphocytes, a statistically significant difference was observed between the high branched-chain amino acids and the 15AA groups. Conclusion High branched-chain amino acids is new, safe and efficient amino acids for parenteral nutrition.
