Objective To evaluate the effectiveness of spiral stone dislodger combined with pneumatic lithotriptor under ureteroscopy for managing upper ureteral stones. Methods 106 patients with upper ureteral stones with spiral stone dislodger combined with pneumatic lithotriptor under ureteroscopy were treated. The transverse diameter of the stones was 4～12mm and the vertical length 6～15mm. Results 87.7% (93/106) stones were fragmented for one session of treatment. 8 cases were pushed upward then undergoing extracorporeal shock wave lithotripsy(ESWL) after surgical operations. Operations in 5 cases had to be changed to open surgery,and ureteral perforations happened in 1 case. Conclusion Successful entrance of the uretersocop is a prerequisite for crushing the stone,appropriate fixation of the stone is the key to their crushing,spiral stone dislodger is an effective means of fixing ureteral stones.

OBJECTIVETo verify the pharmacological hypothesis of prescriptions by studying the targeted distribution of major components in stewed rhubarb in the rat model with acute pancreatitis (AP).

METHODNormal SD rats (control group, n = 5) and the AP model induced with intraperitoneal cerulein (model group, n = 5) were taken as the experimental objects. Rats of the two groups were orally administered with stewed rhubarb granules (20 g x kg(-1)). Their heart, liver, spleen, lung, kidney and pancreas were collected two hours after the administration. Such constituents as emodin, chrysophanol, physcion, rhein and aloe-emodin and their concentrations in each tissue homogenate were detected by high performance liquid chromatography-mass-mass.

RESULTAloe-emodin and physcion in stewed rhubarb whose concentrations in liver and kidney of normal rats were higher than that in pancreatic tissues, while the distribution spectrums and concentrations of the remaining components in pancreatic tissues had no significant difference with that of other organs. The concentrations of emodin, aloe-emodin, rhein and chrysophanol in stewed rhubarb in pancreatic tissues of the AP model group were higher than that in other tissues and organs, while their concentrations in pancreatic, renal and splenic tissues were notably higher than that in the normal group.

CONCLUSIONIn the conditions of AP, effective components in stewed rhubarb show a targeted distribution feature in pancreas, which provides experimental basis for the pharmacological hypothesis of prescriptions.

OBJECTIVETo discuss the effect of surgical staging and using craft bone with vancomycin for the treatment of calcaneal fractures.

METHODSFrom January 2006 to December 2012,13 patients with open calcaneal fractures were treated including 9 males and 4 females with an average of 35.2 years old ranging from 23 to 66. All cases were emergency cases. According to Sanders classification of calcaneal fractures, 2 cases were type II, 7 cases were type III, 4 cases were type IV. According to Gustilo-Anderson soft tissue injury classification, 8 cases were type II, 2 cases were type III A, 2 cases were type III B, 1 case were type III C. Firstly a thorough debridement or VSD procedures were applied,secondly calcaneal fracture were treated with open reduction, plate fixation and bone graft complex with antibiotics. Based on clinical examination, radiographic evaluation, and American Foot and Ankle Surgery Society (AOFAS), ankle function were evaluated after operation.

RESULTSOpen wounds were headed after dressing and repairing,, lateral calcaneal wound were healed during the first period. All patients were followed up for 6 to 36 months (means 14.5 months). Fracture healing time was 14 to 20 weeks (means 16.2 weeks). Last follow-up AOFAS ankle-hindfoot score was (80.0 +/- 7.4) ranging from 55 to 95.

CONCLUSIONFor patients with open fractures, through reasonable clinical evaluation, staging operation, using bone graft with antibiotics can reduce the incidence of postoperative wound infection and promote fracture healing.

The expression levels of IL-12 and IL-12 mRNA in gastric mucosa were determined by ELISA and RT-PCR.Results Inflammation of gastric antral mucosa was more severe in Hp-positive mucosa .The expression levels of IL-12 and IL-12 mRNA in Hp-positive mucosa were (66.42?15.15) ng/g and (59.21?15.03)%,which were more than those in (Hp-negative )(22.22?8.79) ng/g and (17.94?7.39)%(P

Objective To investigate clinical characteristics of relapsing polychondritis(RP)and to improve early recognition for it.Methods Clinical and laboratory data of 56 patients with RP were analyzed retrospectively.Results Ratio of number of male patients to female ones was 1.2.Age at onset was(46?11)years(ranging from 27 to 71)and average interval between onset and diagnosis was(21? 35)months,(8?6),(16?31)and(29?37)months for patients initial onset with auricle,respiratory tract and joints involved,respectively.Site involved included airway in 40 patients(71.4%),auricle in 32 (57.1%),joints in 32(57.1%),eyes in 27(48.2%),nasal chondritis in 25(44.6%)and inner ear in 13(23.2%).At initial stage of the course,17 patients were misdiagnosed as respiratory infection (30.4%),nine as perichondritis(16.1%),six as pulmonary tuberculosis(10.7%),five as rheumatoid arthritis(8.9%).Seven of 40 patients with airway involvement received metallic stents for their tracheobronchial stenosis.Four patients whose condition never improved after regular therapy all had respiratory involvement.Conclusions Patients of RP with initial onset at non-auricle,non-nasal sites tended to be misdiagnosed.Prevalence of airway involvement was not so low with a poor prognosis in patients of RP.

pH, affects of different alkaline materials KOH, K 2CO 3, NaOH, Na 2CO 3 on the growth, and NaCl, KCl tolerance of 29 isolates from the saline and alkaline soils in Xinjiang and Qinghai Provinces of China and 1 type strain were studied. Results showed that only a few alkaliphilic actinomycetes were Na +-obligately dependent, and K +-sensitive. Some alkaliphilic actinomycetes were CO 3 2- -sensitive, and NaCl, KCl could inhibit their growth. 4 kinds of alkaline materials had no affect on growth of alkaliphilic Nocardiopsis, and these strains showed high tolerance to NaCl, KCl. So it was presumed that only K + and CO 3 2- obligately dependent alkaliphilic Actinomycetes maybe exist in alkaline environments.
