Objective To compare the clinical efficacy and safety of Qingyi Decoction (a preparation of Chinese herbal medicine) between two different routes of the administration by using nasogastric tube or nasojejunal tube for treatmnent of severe acute pancreatitis (SAP).Methods A total of 79 SAP patients enrolled were randomly divided into nasogastric tube group (n =41) and nasojejunal tube group (n =38) according to the random number table method.In addition to the conventional therapy,they were treated with Qingyi Decoction administered by using nasogastric tube or nasojejunal tube.Results After treatment for 14 days,the levels of C-reactive protein (CRP),procalcitonin (PCT) and white blood cell count (WBC),urinary bladder pressure,and APACHE Ⅱ score in nasojejunal tube group were significantly lower than those in nasogastric tube group (P ＜ 0.05).The time required for the recovery of bowel sounds,length of abnormal serum amylase persistence,the duration of abdominal pain,the time necessary for mechanical respiratory support in nasojejunal tube group was significantly shorter than those in nasogastric tube group.The blood fungus infection rate and pulmonary fungus infection rate in nasojejunal tube group were significantly lower than those in nasogastric tube group,and 28-day survival rate in nasojejunal tube group was significantly higher than that in nasogastric tube group (P ＜ 0.05).Conclusion The nasojejunal tube route for the administration of Qingyi Decoction for the treatment of SAP can effectively alleviate the severity of patient's condition,shorten the time required for improving clinical symptoms,reduce the incidence of morbidity and mortality,and it is worthy of further popularization in clinical practice.

Objective To study the MRI signs of primary central nervous system lymphoma(PCNSL).Methods MRI features of PCNSL in 44 patients proven by pathology from January 2004 to September 2005 were analysed retrospectively.There were 29 men and 15 women,the age ranged from 12~76 years old with mean 53.Results The lesions localized at brain in 41 patients and spinal cord in 3.The lesions were multiple and single.The lesions were hypointense on T1WI and isointense or hyperintense on T2WI mostly.Nearlly all the lesions had parenchymatously massive or nodular enhancement,the minority has ring-like enhancement post contrast-enhanced scan.Conclusion PCNSL has certain MRI characteristic.The solitary or multiple lesions with obviously nodular enhancement,especial contact with cerebrospinal fluid space,the possibility of PCNSL diagnosis should be consider.

Objective To investigate the clinical effect of blocking nail in treatment of hypertrophic nonunion after interlocking intramedullary nailing of femoral shaft fractures.Methods A retrospective case series study was made on 11 patients with hypertrophic nonunion following interlocking intramedullary nailing of femoral shaft fractures from January 2006 to February 2016.There were 8 males and 3 females,aged (32.4 ± 6.8) years (range,19-48 years).Comminuted fractures were noted in three patients,long oblique or spiral fractures in two,multi-segment fractures in two,and transverse fractures in four.Time interval between this surgery and intramedullary nailing of femoral shaft fractures was (11.5 ±3.1) months (range,6-18 months).All blocking nails were inserted into pulp cavity of distal ends of the site of the bone nonunion.Fracture healing time,wound healing and postoperative complications were detected.Outcome was evaluated using the Visual Analogue Scale (VAS) and Oswestry Disability Index (ODI).Results All patients were followed up for (27.2 ± 4.6) months (range,24-36 months).Bone union was observed within (9.8 ± 3.4) months except that bone nonunion occurred in two cases requiring locking plate fixation and autologous bone grafting to provide union,with the healing rate of 91％.No wound infection,nail breakage and nail loosening occurred after operation.At postoperative 3 months,4 months,5 months,6 months,12 months and 24 months,VAS and ODI differed significant from the preoperative detections (P ＜ 0.05).Conclusion Blocking nail technique is associated with increased stability of intramedullary nails and fracture ends,low incidence of complications and high bone healing rate in treatment of hypertrophic nonunion after femoral interlocking intramedullary nailing.

Diabetic rats were induced by intraperitoneal injection of streptozotocin.TUNEL and immunohistochemistry results showed that the renal tubular cell apoptosis index(AI)and Bax protein expression were significantly reduced,and the Bcl-2 protein expression in glomeruli was significantly increased in diabetic rats with stable hyperglycemia treated by benazepril compared with diabetic rats with stable hyperglycemia treated by vehicle(all P

Objective To investigate the clinical characteristics of cervical spine injury associated with chest injury by contrast with simple cervical spine injury.Methods A retrospective analysis was performed on records of 116 patients with cervical spine injury hospitalized from March 2009 to September 2014.There were 65 patients with simple cervical spine injury (simple injury group) and 51 patients with associated chest injury (associated injury group).Data recorded were the causes of injury, injury segment, treatment choices (tracheotomy rate, mechanical ventilation use and non-operative treatment), treatment time (operation rate at different time, time from injury to operation and length of hospital stay) , complications (electrolyte disorder, respiratory infection, respiratory dysfunction or failure, urinary tract infection, gastrointestinal bleeding and multiple organ dysfunction syndrome), and treatment outcome.Results The main cause of injury for the two groups was high falling.Lower cervical segment was the most likely to be affected.Significant differences were detected between the simple injury group and associated injury group with regard to tracheotomy rate (63％ vs.42％), rate of mechanical ventilation (41％ vs.25％), rate of early surgery (29％ vs.58％), rate of delayed surgery (69％ vs.30％), time from injury to operation [(7.2 ± 3.7) d vs.(3.1 ± 1.3) d], length of hospital stay [(22.6-± 5.5) d vs.(17.3 ± 3.7)d], electrolyte disorder rate (35％ vs.17％), incidence of respiratory system infection (55％ vs.35％), and respiratory dysfunction (43％ vs.25％) (P ＜0.05).After treatment, American Spinal Injury Association (ASIA) scale for grade D was significantly lower in associated injury group than in simple injury group (25％ vs.39％ P ＜ 0.05).Conclusion Cervical spine injury associated with chest injury is severe injury, often requiring tracheotomy and mechanical ventilation, and demonstrates difficulties to be effectively treated in the early phase, long hospitalization, various complications and high morbidity.

Objective To study effects of early non-invasive ventilation (NIV) application in treating elderly patients with acute left ventricular failure induced respiratory failure. Method Totally 32 elderly patients with acute left ventrieular failure induced respiratory failure, admitted from August 1997 to February 2007, received NIV treatment, and were retrospectively studied. There were 22 male and 10 female, aged (81.5?8.6) yearsdd. The changes of rahs, respiration rate, heart rate, arterial blood gas, cardiac function before and after NIV application were compared. According to the application time of NIV, 32 patients were divided into two groups: group A (early NIV application group, n=17) and group B (non-early NIV application group, n= 15). The time to improve the symptoms, the application time of NIV, cure rates, tracheal intubation rates and mortality were compared between the two groups. Results Thirty of the 32 patients survived, cardiac function was improved from New York classⅣtoⅠ～Ⅱ, respiratory rate, heart rate and blood pressure significantly decreased, PaO_2 and SaO_2 significantly increased and PaCO_2 significantly decreased. The tracheal intubation was performed in 4 patients. The time needed to improve the symptoms and the application time of NIV were significantly different between group A and group B (P

Objective To retrospectivel y analyze the abdominal CT findings and pathological results of the chronic schist osomiasis so as to improve the diagnostic accuracy of the disease. M ethods The plain abdominal CT scanning was performed in 103 cases an d enhanced CT scanning in 81 cases. The pathological specimen which was consist ent with the section of CT scan was obtained in each cases. Results On CT scanning, liver cirrhosis was seen in 84 cases, various calci fication in liver in 71 cases, liver cancer in 12 cases, enlargement of sple en in 78 cases, calcification in spleen in 13 cases, wall-thickening in colon i n 27 cases, calcification in colon in 31 cases, and colon cancer in 9 cases. Pa thological examination revealed various fibrosis and formation of pseudolobule. The eggs and calcification could be seen in pseudolobule and septa, colonic sub mucosa, and regional lymph nodes. Fibrous hyperplasia in colonic wall and hyper plasia in mucous membrane were obvious. Fibrous hyperplasia and calcification w ere seen in spleen, but the eggs were not found. Conclusion The liver and colon are the major organs affected by chronic schistosomias is in abdomen, and the CT findings are obvious too. The pathological features o f spleen are accompanied with liver cirrhosis. CT is the important imaging meth od in diagnosing chronic schistosomiasis and pathological changes.

Aim To investigate whether D-galactose cause osteoporosis and the difference compared with the osteoporosis induced by ovariectomy, and to deter-mine whether ovariectomy coupled with D-galactose ac-celerated the progress of osteoporosis and whether es-trogen had a preventive effect on these osteoporosis models. Methods Sixty SPF mice were randomly divided into six groups , namely sham-operated group, D-galactose group, OVX group, OVX + D-galactose group, OVX + D-galactose + diethylstilbestrol group and D-galactose + diethylstilbestrol group. Seventy days later, the right tibia was processed with undecal-cified sections for bone histomorphometric analysis. Results Compared with the sham-operated group, %Tb. Ar, Tb. Th and Tb. N decrease by 50. 4%, 25. 4%, 50. 9% ( P <0.01 ) respectively, Tb. Sp in-creased by 169. 4% (P <0.05), Oc. pm, Oc. No. ,%Oc. S, Oc. N/mm which reflected bone absorption significantly increased ( P < 0.01 ) , and % L. Pm, MAR, BFR/TV, BFR/BV, BFR/BS which reflected bone formation significantly decreased ( P <0.01 ) in OVX group. %Tb. Ar decreased by 30. 4% in D-ga-lactose group, but there was no statistically significant difference. However, the four parameters reflected the bone absorption in D-galactose group increased signifi-cantly ( P<0.05 ) , while the four parameters reflected bone formation decreased significantly ( P < 0.05 ) . OVX+D-galactose group has obvious performance of osteoporosis, but there was no significant difference compared to OVX group, nor to D-galactose group. Estrogen had significant preventive effect on related pa-rameters of osteoporosis induced by D-galactose and o-variectomy coupled with D-galactose. ConclusionsOsteoporosis model of mice can be established by OVX, D-galactose and OVX +D-galactose. Estrogen can effectively prevent bone loss induced by D-galac-tose and OVX+ D-galactose.

Congenital cataract is a highly heterogeneous disorder at both the genetic and the clinical-phenotypic levels. A unique cataract was observed in a 4-generation Chinese family, which was characterized by autosomal dominant inheritance and late-onset. Mutations in the 13 known genes (CRYAA, CRYAB, CRYBB1, CRYBB2, CRYGC, CRYBA1/A3, CRYGD, Connexin50, Connexin46, intrinsic membrane protein LIM2, cytoskeletal protein BFSP2, the major intrinsic protein-MIP and the heat shock factor HSF4) have previously been demonstrated to be the frequent reason for isolated congenital cataracts, but the exact molecular basis and underlying mechanisms of congenital cataract still remain unclear. This study was designed to find whether these 13 genes developed any mutation in the family members and to identify the disease-causing gene. Polymerase chain reaction (PCR) and direct DNA sequence analysis were carried out to detect the 13 genes. The results showed that no mutation causing amino acid alternations was found in these potential candidate genes among all patients in the family, and only several single-nucleotide polymorphisms (SNPs) were identified. A transitional mutation in the fourth intron of CRYBB2 and some silent mutations in the first exon of BFSP2 and CRYGD were found in the cataract family, but further study showed that these mutations could also be found in normal controls. It was concluded that some unidentified genes may underlie the occurrence of late-onset cataract in this family. A genome-wide screening will be carried out in the next study.

OBJECTIVETo evaluate the therapeutic effects of mitral valve repair for the treatment of the anterior leaflet prolapse of mitral valve.

METHODSFrom November 1998 to October 2007, 210 patients with severe anterior leaflet prolapse of mitral valve underwent valve repair. The condition of valve was preoperative, intraoperative, and postoperative assessed with echocardiography.

RESULTSEdge-to-edge repair technique was used in 134 cases (63.8%). The cardiac function was NYHA class I in 168 cases and class II in 40 cases after operation. Patients were followup for 1 - 150 (25.7 +/- 29.0) months, two patients (0.95%) died of postoperative low cardiac output syndrome. Echocardiography examination indicated that the mean JP2 postoperative left atrial diameter was (37.7 +/- 9.2) mm against the preoperative value of (47.5 +/- 12.7) mm (P < 0.05), the mean postoperative left ventricular end-diastolic diameter was (51.7 +/- 7.9) mm against the preoperative value of (67.7 +/- 10.3) mm (P < 0.05), the mean postoperative left ventricular ejection fraction was (62.2 +/- 3.2)% against the preoperative value of (52.2 +/- 6.4)% (P < 0.05), and the mean preoperative regurgitation area was (10.4 +/- 4.1) cm(2) against the postoperative value of (4.1 +/- 1.7) cm(2) (P < 0.01).

CONCLUSIONSOptimal outcome was achieved by appropriate edge-to-edge technique or other mitral valve repair techniques for anterior leaflet prolapse of mitral valve. Edge-to-edge technique is a reliable and efficient surgical technique.
