To evaluate the clinical efficacy and safety of Qinghouyan lozenge in the treatment of acute pharyngitis due to Lung-heat and Yin-deficiency, and compare with Qinghouyan oral Liquid. Totally 144 subjects were enrolled and randomly divided into two groups (72 in the test group and 72 in the control group). The participants in the test group were given Qinghouyan lozenge for 5 days, and those in the control group were given Qinghouyan oral Liquid for 5 days. The effectiveness evaluation indexes were pharyngalgia/odynophagia disappearance rate, overall efficacy of TCM syndromes, TCM syndrome scores, and single syndrome and sign disappearance rate. During the test, the safety was evaluated by vital sign, lab examination indexes and adverse events. The results for the full analysis set showed that the couth disappearance rate, the incidence rate of TCM syndromes, and the throat/uvula congestion disappearance rate of the test group were higher than that of the control group (P < 0.05), with significant differences in the changes in syndrome scores between the two groups (P < 0.05). Altogether 3 adverse events were observed in the test group while 6 adverse events in the control group, without significant differences in the adverse event rate between the two groups (P < 0.05), serious abnormal laboratory examinations and vital signs. In conclusion, Qinghouyan lozenge has better efficacy in treatment of acute pharyngitis due to Lung-heat and Yin-deficiency than Qinghouyan oral liquid, with good safety.

Background Salivary transplantation or duct transposition can provide continuous physiological secretion of tear substitutes.This may be an ideal method in treatment of dry eye.But the relative anatomical literatures is few,and some of the conclusions in the literatures are still controversial,which limit its clinical application.Objective This study was to discuss the possibility and the advantage and disadvantage of applying three major salivary glands to treat xerophthalmia.Methods The relationship between the branches of the facial nerve out of the parotid gland and the salivary glands,the salivary glands size,origin of blood supply,out diameter of vessels and adjacent relation were observed in 34 sides pate specimens perfused with red latex under the operating microscope.To find the vessels in recipient site to anastomose,the vessels around fossa orbitalis and forehead were anatomized and observed.The parotid gland duct transfer operation,the submandibular gland free transplantation surgery and sublingual gland free transplantation surgery in the human anatomy specimens were simulated.Results The position of parotid duct was constant.The duct length was(4.20± 1.10) cm,duct diameter was (O.60±0.30) cm.The stensen's duct was likely to be prolonged by the cheek mucous membrane or venous andthe damage of buccal branch,zygomatic branch and temporal branches of facial nerve should be avoided during the operation of transplanting stensen' s duct.When submandibular gland was transplanted,facial vessel was taken as its pedicle,whose outside diameter was (2.70 ± 0.28) mm,and the length of the transplant vascular pedicle was (1.90 ± O.30) cm.Thc anastomosed vessel was superficial temporal vessel in recipient site.When sublingual gland was transplanted,sublingual(88.2％,30 sides) or submental vessel(11.8％,4 sides) was taken as its pedicle,whose outside diameter was(1.92±0.36) mm and (1.96±0.54) mm,and the length of the transplant vascular pedicle was(2.60± 1.10) cm and(3.50±0.40) cm,and the anastomosed vessel was the frontal branch of superficial temporal vessel in recipient site.Three sides of specimens lacked sublingual glands.Conclusions It is feasible that treating severe xerophthalmia by the operation of grafting the major salivary glands or transplanting stensen' s duct on the point of anatomical view.Parotid duct inversion and the submandibular gland transplantation have been applied to clinic.However,sublingual transplantation remains to be further confirmed by the animal experiments.

Objective To investigate effectiveness of anthropometric parameters and body composition analysis for the screening and prediction of metabolic syndrome and explore the best indicator for predicting metabolic syndrome in the elderly. Method A cross-sectional study of 763 (406 men and 357 women) elderly people who participated in the annual health check-up was conducted. Clinical data of all participants were obtained including anthropometric parameters, body composition, lipid profiles, fasting blood glucose, and high sensitivity C-reactive protein. Receiver operating characteristic (ROC) curve was used to determine the optimal cutoff points for waist circumference, waist-to-hip ratio, waist-to-height ratio, percent body fat and fat mass index in relation to the area under the curve (AUC), sensitivity and specificity in the screening and prediction of metabolic syndrome. Result In total subjects, compared with non-metabolic syndrome group,the ROC curve analysis showed that parameters including waist circumference, waist-to-height ratio, waist-to-hip ratio, percent body fat and fat mass index had a significant potential for predicting metabolic syndrome (P<0.001). It was determined that waist circumference of 87.5 cm and 77.5 cm, waist-to-hip ratio of 0.89 and 0.87, waist-to-height ratio of 0.51 and 0.52, percent body fat of 24.1%and 31.7%and fat mass index of 5.00 kg/m2 and 7.80 kg/m2 were the optimal cutoff points for screening and predicting the presence of metabolic syndrome among men and women with a sensitivity of 81.3%,78.8%,87.5%, 51.3%and 83.8%(in men) and 85.1%,79.8%,71.3%, 70.2%and 80.9%(in women) and a specificity of 57.7%,62.6%,50.0%, 75.5%and 51.8%(in men) and 38.0%,53.2%,55.1%, 50.6%and 52.5% (in women),respectively. The area under the ROC curve (AUC) was 0.728, 0.755, 0.716, 0.671 and 0.725 in men and 0.652, 0.707, 0.658, 0.619 and 0.675 in women,respectively. Waist-to-hip ratio showed the highest AUC in all the parameters in men and women. Conclusion Anthropometric parameters and body composition analysis play important roles in the screening and prediction of metabolic syndrome, and waist-to-hip ratio seems to be the best parameter in the screening and prediction of metabolic syndrome in the elderly.

Objective To investigate the mechanisms of Mieyou Decoction in the treatment of Hp-associated gastritis of spleen-stomach damp-heat syndrome. Methods Seventy BALB/c mice were randomly divided into control group, model group, high concentration of Mieyou Decoction group, low concentrations of Mieyou Decoction group, and gastric triad group, with 14 rats in each group. BALB/c mice of Hp-associated gastritis of spleen-stomach damp-heat syndrome models were established by composite factor. After the success of modeling and continuous 14-day administration, the expressions of TLR2, TLR4 protein, TLR2 mRNA, and TLR4 mRNA were detected by immunohistochemistry and qPCR. ELISA was used to detect the expressions of IL-6 and IL-8 in the serum. Results Compared with control group, the expressions of TLR2, TLR4 protein, mRNA, IL-6, and IL-8 in model group significantly increased (P<0.01);the expressions of TLR2, TLR4 protein, mRNA, IL-6, and IL-8 in high concentration of Mieyou Decoction group, low concentrations of Mieyou Decoction group, gastric triad group were lower than model group, with statistical significance (P<0.01);the expressions of TLR2, TLR4 protein, mRNA, IL-6, and IL-8 in high concentration of Mieyou Decoction group were higher than gastric triad group, but the differences were not statistically significant (P>0.05). Conclusion Mieyou Decoction may play a role in the treatment of Hp-associated gastritis of spleen-stomach damp-heat syndrome through intervention in the expressions of TLR2 and TLR4.

Conclusion Mieyou Soup may play a role in treatment of H.Pylori-associated gastritis mice of Pi-Wei hygropyrexia syndrome by raising the expression of HSP70, and reducing the expression of AQP4 protein expression.

Objective To evaluate the cardioprotection induced by ischemic preconditioning ( IPC) and hypoxic preconditioning ( HPC) which were carried out by using the double cardiopulmonary bypass ( CPB) circuits in in vivo hearts of dogs. Methods Eighteen healthy male dogs, weighing 17?5-24?5 kg, aged 13-24 months, were divided into 3 groups ( n=6 each) using a random number table: my?ocardial ischemia?reperfusion group (group I∕R), IPC group and HPC group. The double CPB circuits were established as follows: systemic and coronary circulation, and independent systemic and coronary cir?culation was carried out. In group IPC, the aorta was clamped, and the coronary circulation pump was sus?pended for 5 min followed by 5 min opening, repeating for 3 cycles. In group HPC, the aorta was clamped, the coronary circulation was started, and pure nitrogen was insufflated for 5 min followed by 5 min of oxygen insufflation, repeating for 3 cycles. CPB was performed for 1 h starting from the time point immediately after IPC or HPC. Before splitting of sternum ( T1 ) , after establishment of double CPB circuits ( T2 ) , at the end of preconditioning ( T3 ) , and at 60 and 120 min after restoration of spontaneous heart
beat ( T4,5 ) , heat rate, mean arterial pressure, central venous pressure, left ventricular end?systolic pres?sure, left ventricular end?diastolic pressure and the maximum rate of increase∕decrease of left ventricular pressure were recorded. Blood samples were collected from the right internal jugular vein at T1 and T4,5 for determination of serum cardiac troponin I concentrations. The animals were sacrificed after determination of the parameter or after blood sampling at T5 , myocardial specimens were obtained for examination of the ul?trastructure and for detection of apoptosis in cardiomyocytes, and apoptosis index was calculated. Before aortic clamping, immediately after aortic unclamping and at 30 min after aortic unclamping, myocardial specimens were obtained for determination of ATP contents in cardiomyocytes. Results Compared with I∕R group, left ventricular end?systolic pressure was significantly increased, and the serum cardiac troponin I concentrations were significantly decreased at T4,5 , the myocardial ATP contents were significantly in?creased immediately after aortic unclamping and at 30 min after aortic unclamping, apoptosis index was sig?nificantly decreased ( P<0?05 or 0?01) , and the pathological changes were significantly attenuated in IPC and HPC groups. Compared with group IPC, the myocardial ATP contents were significantly increased (P<0?05), and the pathological changes were attenuated in group HPC. Conclusion Both HPC and IPC can exert cardioprotection when carried out by using the double CPB circuits, and HPC provides better cardioprotection than IPC in in vivo hearts of dogs.

Objective To study the mid-and long-term outcomes and prognostic risk factors of mitral valve replacement (MVR) in children.Methods Retrospectively studied the cases(＜ 14 years) receiving MVR between July 2003 and March 2014 in our hospital,and recorded the gender,age,operation related data and the results of echocardiography,electrocardiogram and chest X-ray in the out-patient department.Results A total of 48 patients were followed up.Age was 8 months 15 days-13 years 9 months and 22 days,the average was (9.5 ± 3.9) years.24 cases were original operations,others were second operations.43 mechanical valves were used,as well as 5 tissue valves.The mortality was 8.3 ％ and the incidence of complications was 25.0％ during the hospitalization or within 30 days after the operations.Follow-up time was 4.7-150.7 months,the average was(62.0 ± 42.3) months.The long-term mortality was 9.1％,and the incidence of complications was 9.4％.Follow-up of left ventricular ejection fraction was 0.30-0.77,the average was 0.61 ±0.08.There was no redo-MVR or implantation of pace maker.The survival rates of 1 year,5 years and 10 years were (89.5 ± 4.5) ％、(83.0 ± 6.1) ％、(77.8 ±7.6)％,respectively.Children younger than 5 years was the risk factor for perioperative mortality or complications (OR =8.47,95％ CI:1.36-52.61).Children with perioperative complications was the risk factor for long-term mortality or complications(OR =9.97,95％ CI:1.39-71.76).Conclusion The results of children with MVR were satisfactory.To perform MVR in children older than 5 years if possible and to reduce the incidence of perioperative complications could improve the prognosis.

Laparoscopic curative gastrectomy has been widely adopted because it is minimal invasiveness.The efficacy of laparoscopic gastrectomy is comparable to that of open gastrectomy for patients with early or advanced gastric cancer,but few studies of laparoscopic total gastrectomy combined with distal pancreatectomy and splenectomy for patients with advanced gastric cancer have been reported.Seven patients with advanced gastric cancer received laparoscopic total gastrectomy combined with distal pancreatectomy and splenectomy at the First Hospital of Jilin University from September 2010 to September 2011.The mean operation time,blood loss,postoperative hospital stay and the nunber of lymph nodes resected were (218 ± 24) minutes,(366 ± 174) ml,( 14.6 ± 2.8 ) days and 32 ± 15,respectively.Two patients were complicated by pancreatic juice leakage and were cured with drainage. No anastomotic leakage,abdominal bleeding or mortality was observed. With the development of techniques and equipments,laparoscopic total gastrectony combined with distal pancreatectomy and splenectomy is safe and feasible in selected patients.

Purpose To explore the immunohistochemical ( IHC) expression of ALK antibodies with different clones in anaplastic lym-phoma kinase ( ALK) gene fusion non-small cell lung cancer ( NSCLC) . Methods ALK expression in 60 NSCLCs were detected by IHC including autostainer (D5F3, Ventana+BenchMark) and manual staining using 4 different antibodies of D5F3 (Ventana), D5F3 (Cell Signaling), 1A4/1H7 (OriGene), 5A4 (Abcam), and all cases were verified with ALK FISH. Their expressions with 4 anti-bodies were compared with those by D5F3 (Ventana+BenchMark). Results 32 ALK gene rearrangement NSCLCs and 28 negative cases were identified by FISH and D5F3 (Ventana+BenchMark). The sensitivity of D5F3 (Ventana), D5F3 (Cell Signaling), 1A4/1H7 (OriGene), 5A4 (Abcam) was 93. 8%, 84. 4%, 93. 8%, 56. 3%, and all the speciticity was 100%. The consistency with D5F3 (Ventana+BenchMark) was 96. 7%, 91. 7%, 96. 7% and 76. 7%, respectively. The validity of immunohistochemical staining in surgical resection specimens was better than in small biopsies. Conclusion Effective routine manual immunohistochemistry with high-affinity antibody clone may provide a more economic and widespread pre-screening technique.
