OBJECTIVE:To evaluate the clinical efficacy of Shuanghuanglian injection in the treatment of acute exacerbation of chronic obstructive pulmonary disease (AECOPD),and to observe its effects on the plasma levels of C-reactive protein (CRP),procalcitonin(PCT)and interleukin-6(IL-6). METHODS:A total of 100 AECOPD patients were randomly divided into observation group and control group,with 50 cases in each group. Control group received routine treatment,such as controlled oxygen therapy,intravenous dripping of moxifloxacin,bronchodilator for relieving asthma,mucolytic for eliminating phlegm,nu-tritional support. Observation group was additionally given Shuanghuanglian injection 1 ml/(kg·d)added into 5% Glucose injec-tion 250 ml intravenously,qd,on the basis of control group. Treatment course of 2 groups lasted for 10 d. Clinical efficacies of 2 groups were compared as well as the changes of serum levels of CRP,PCT and IL-6 before and after treatment and the occur-rence of ADR. RESULTS:After treatment,total effective rate of observation group was 96.0%,which was significantly higher than 82.0% of control group,with statistical significance(P<0.05). Before treatment,there was no statistical significance in se-rum levels of CRP,PCT and IL-6 between 2 groups (P>0.05). After treatment,serum levels of CRP,PCT and IL-6 were de-creased significantly in 2 groups,and those of observation group were significantly lower than those of control group,with statis-tical significance (P<0.05). There was no statistical significance in the incidence of ADR between 2 groups (P>0.05). CON-CLUSIONS:Shuanghuanglian injection can effectively improve serum inflammatory factors of AECOPD patients,and shows good clinical efficacy and safety.

Objective To study the integration and expression of HLA-B2704 gene in HLA-B2704 transgenic mice. Methods HLA-B2704 gene was introduced into fertilized eggs of C57BL/6?Kunming and Kunming?Kunming by microinjection. The founder mice were screened by PCR for integration of HLA-B2704 transgene and were then further confirmed by southern blot. RT-PCR and flow cytometry were carried out to detect the expression of HLA-B2704 gene at mRNA and protein level. Results Ten F0 hybrid mice carried HLA-B2704 gene in 101 F0 hybrid mice, 3 of 64 (4.7%) hybrid mice from Kunming?Kunming and 7 of 37 (18.9%) hybrid mice from C57BL/6?Kunming background carried HLA-B2704 gene. Statistical analysis showed that there was significant difference in the integration rate between the two groups (P

Objective To study the gait of children with spastic cerebral palsy (SCP) using plantar pressure measurement (PPM).Methods Twenty SCP children and 84 healthy children were recruited,and PPM was used to compare their gait cycle time,cadence,and standardized gait cycle parameters.Results Compared with the control group,gait cycle times in the SCP group were obviously prolonged,and their cadence was significantly slower.The side support phase and swing time in the SCP group were shorter,while the double support phase was longer than that of children in the control group.Conclusion PPM can be used to assess the gait of SCP children efficiently.

Background and purpose:It is difficult to diagnose gastric cancer at an early stage,thus the resectable probability of gastric cancer is low.This study was to explore the efficacy of neoajuvant chemotherapy in terms of resectablity for the patients with advanced gastric cancer.Methods:Eighty-six patients with advanced gastric cancer were randomly divided into routine surgical operation group and neoajuvant chemotherapy+surgical operation group.The patients were examined by CT before surgery.The patients in neoajuvant chemotherapy+surgical operation group received two cycles of neoajuvant chemotherapy,and then were evaluated by CT.Results:In routine surgical operation group,the overall resectability rate was 83.7%(36/43),and the curative resection rate was 46.5%(20/43), 16.3%(7/43)was done by exp.lap.In neoajuvant chemotherapy+surgical operation group,the overall resectability rate was 93.0%(40/43),and the curative resection rate was 69.8%(30/43),only 7.0%(3/43)was exp.lap.No mortality was observed.There were no significant difference between both groups in terms of toxicities.Conclusions:The overall resectability rate and the curative resection rate are increased in patients with advanced gastric cancer aider neoajuvant chemotherapy.

OBJECTIVETo investigate results of total knee arthroplasty using the long-stem tibial component combined with metallic wedge of knee prosthesis for the treatment of proximal defects.

METHODSFrom January 2011 to May 2013, 10 patients (11 knees) were treated with total knee arthroplasties using the long-stem tibial component with metallic tibial wedge of knee prosthesis. All the patients were female and the average age was 67 years old (ranged, 60 to 77 years old). All the patients were osteoarthritis. All the patients were classified as T2A style. The patients were evaluated according to knee score system (KSS).

RESULTSAll the patients were followed up for 12 months on average (ranged 3 to 29 months). The clinical outcome was assessed using KSS score, including knee pain score, knee stability score, knee range of motion score and knee walking score, knee stairs score. There were significantly differences at 6 weeks, 3 months, 6 months and 12 months between pre-and postoperative KSS score.

CONCLUSIONThe mechanical stability of tibial fixation in primary TKA is significantly increased by using the long-stem tibial component with metallic wedge of knee prosthesis, even in the presence of poor proximal bone.

Objective To confirm the predictive value of diaphragm thickening fraction (DTF) on successful weaning by bedside ultrasound in patients with myasthenia gravis crisis. Methods A prospective study was conducted. The patients with myasthenia gravis crisis undergoing mechanical ventilation admitted to Department of Critical Care Medicine of the Affiliated Hospital of Qingdao University from March 2015 to February 2017 were enrolled. All patients underwent a low level pressure support mode of spontaneous breathing test (SBT), and rapid shallow breathing index (RSBI) was recorded. The indicators of right diaphragm thickness at the end of inspiration (DTei) and expiration (DTee) were determined by bedside ultrasound at 5 minutes and 60 minutes of SBT, and DTF was calculated, the changes in above parameters were observed during SBT. The patients were divided into successful weaning group and failure weaning group, and the differences in above indexes were compared between the two groups. Receiver operating characteristic curve (ROC) was used to evaluate the predictive value of DTF and RSBI at 60 minutes of SBT on successful weaning. Results A total of 37 patients were enrolled in the study. Ultrasonic measurement data of 63 person-times at 5 minutes of SBT and 50 at 60 minutes of SBT were obtained. There were no statistical differences in RSBI, DTei, DTee, and DTF at 5 minutes of SBT between successful weaning group (n = 33) and failure weaning group (n = 30). At 60 minutes of SBT, compared with successful weaning group (n = 33), the patients in failure weaning group (n = 17) had a higher RSBI (times·min-1·L-1: 80.41±29.08 vs. 63.94±23.84, t = 2.146, P = 0.037), and lower DTee, DTei and DTF [DTee (mm): 22.00±6.25 vs. 25.45±4.99, t = 2.127, P = 0.039; DTei (mm): 27.94±6.19 vs. 38.48±6.15,t = 5.731, P = 0.000; DTF: (24.46±14.11)% vs. (62.04±30.21)%, t = 4.845, P = 0.000]. There were no statistical differences in RSBI, DTei, DTee, and DTF between 5 minutes and 60 minutes of SBT in 33 person-time successful weaning (all P > 0.05). In 17 person who had 60 minutes of SBT but failed weaning, the RSBI at 60 minutes of SBT was significantly higher than that at 5 minutes (times·min-1·L-1: 80.41±29.08 vs. 57.29±22.46, t = 2.400, P = 0.029), and DTei and DTF were significantly decreased [DTei (mm): 27.94±6.19 vs. 35.35±6.84, t = 3.024, P = 0.000; DTF:(24.46±14.11)% vs. (61.89±23.97)%, t = 5.810, P = 0.000], but the change of DTee during SBT showed no statistical significance. ROC curve analysis showed that the area under ROC curve (AUC) of DTF at 60 minutes of SBT for predicting successful weaning was 0.898; when DTF ≥ 27.9% as the cut-off point, the sensitivity was 93.9%, specificity was 70.6%. The AUC of RSBI for predicting successful weaning was 0.669; when RSBI ≥ 86.50 times·min-1·L-1 as the cut-off point, the sensitivity was 81.8%, specificity was 52.9%. Conclusion DTF at 60 minutes of SBT is the effective index of successful weaning prediction in mechanical ventilation patients with myasthenia gravis crisis.

Objective To compare the effects of biphasic square waveform (BSW) with low or high energy on external defibrillation.Method Adult swine model of closed chest ventricular fibrillation induced by electricity was established.Eighteen swine,weighing (30?3.3) kg were randomly divided into three groups:50-50-50 J group (n=6),30-50-75 J group (n=6),120-150-200 J (n=6).After three minutes of ventricular fibrillation without treatment,the pigs in the three groups were defibrillated accordance to the above sequences. Results 30 J BSW didn't succed to external defibrillate.The first defibrillation successful rate of 50 J and 120 J BSW was 5/6.The total defibrillation successful rate of every group was 100%.All pigs quickly had spontaneous circulation after defibrillation and survived more than 24 hours.ST-T change of low-energy was less than that of high-energy.After resuscitation,myocardial function decreased,but there had not significant differences between groups.Conclusions In the study,30J BSW could not reach successful defibrillation,and 50 J and 120 J BSW had similar defibrillation efficacy.The ideal energy of BSW external defibrillation was 50 J.

Objective To observe Meissner's corpuscles in prepuces of different shapes and ages. Methods The Meissner's corpuscles were detected with immunohistochemical stain in 204 prepuce sam- ples of different shapes and ages (3-59 years),and the density of Meissner's corpuscles in every sample was obtained as well.The difference of Meissner's corpuscle densities between phimosis and redundant pre- puce,and correlation between Meissner's corpuscle densities and ages were analyzed with Chi-square test and linear regression,respectively.Results The density of Meissner's corpuscles in redundant prepuce has begun to increase since infancy and reached the peak at the age about 15 years.No significant difference in densities of Meissner's corpuscles between phimosis and redundant prepuce was observed till the age of 20 years,and then there was a trend of disappearance of Meissner's corpuscles in redundant prepuce.A signifi- cantly negative correlation between the densities of Meissner's corpuscles and ages was revealed in redundant prepuce (r=-0.236,P=0.009),whereas an insignificantly positive correlation between the densities of Meissner's corpuscles and ages was shown in phimosis (r=0.193,P=0.084).Conclusions The den- sities of Meissner's corpuscles in redundant prepuce develop synchronically with genital differentiation and accord with the status of sexual function in adult males.The persistent high level of Meissner's corpuscles in adult phimosis might be a mechanism of physiological compensation.
