BACKGROUND:There was a variety of surgery treatment method in senile patients with unstable intertrochanteric fractures, such as hip replacement and internal fixation, but there was a great deal of controversy about advantages and disadvantages of different methods.
OBJECTIVE:To evaluate clinical effect and safety of total hip replacement, hemiarthroplasty and proximal femoral nail in senile patients with unstable intertrochanteric fractures.
METHODS:103 senile patients with unstable intertrochanteric fractures were selected, including 43 males and 60 females at the age of 62 to 80 years old. There were 28 cases of total hip replacement, 34 cases of hemiarthroplasty and 41 cases of proximal femoral nail. Perioperative complications and recovery of hip function after repair were compared among three groups.
RESULTS AND CONCLUSION:(1) The incidence of postoperative complications of internal medicine was higher in the proximal femoral nail group than in the total hip replacement and hemiarthroplasty groups (P < 0.05). No significant difference in the incidence of complications was found between the hemiarthroplasty and total hip replacement groups. (2) The incidence of prosthesis complications was lower in the total hip replacement group than in the hemiarthroplasty and proximal femoral nail groups (P < 0.05). No significant difference in the incidence of prosthesis complications was detectable between the total hip replacement and hemiarthroplasty groups. (3) The recovery of hip function was better in the total hip replacement and hemiarthroplasty groups than in the proximal femoral nail group during 12-month folow-up (P < 0.05), and no significant difference in the recovery of hip function was found between the total hip replacement and hemiarthroplasty groups. These results showed that total hip replacement and hemiarthroplasty had good curative effect on unstable intertrochanteric fractures in senile patients, and could effectively restore the hip function and reduce complications.

Objective:To evaluate the clinical effects of amended concave position in gynecological laparoscopy surgery.Methods: Eighty ASAⅠ~Ⅱ patients with gynecological laparoscopy surgery were randomly divided into two groups, the patients in group A were adopted Trendelenburg position; the patients in group B were adopted amended concave position. The Ppeak and PETCO2 in the two groups were recorded during surgery, the time of extubation and the adverse effects as nausea, vomiting, shivering was recorded after surgery.Results: The Ppeak and PETCO2 of group A were higher than that of group B(t=2.526,t=2.838, t=2.881;P<0.05). The time of extubation of group A were higher than that of group B after surgery(t=2.515,t=2.436;P<0.05).Conclusion: Adopting amended concave position can reduce Ppeak and PETCO2 in gynecological laparoscopic surgery, and it is helpful for postoperative recovery of the patients with gynecological laparoscopy surgery.

Objective To evaluate the postoperative analgesic effects of parecoxib for laparoscopic urological surgery.Methods Forty patients with ASA scale ofⅠto Ⅲ underwent laparoscopic urological surgery were randomly divided into two groups: the flurbiprofen group(group Ⅰ,n=20) with IV flurbiprofen 100 mg at 2 hours after operation,and 100 mg twice a day during 3 days after operation;and the parecoxib group(group Ⅱ,n=20)with IV parecoxib 40 mg at 2 hours after operation,and 40 mg twice a day during 3 days after operation.The VAS score at 2,4,16,24 and 48 hours after operation and the adverse effects were recorded.Results The average VAS score of the two groups was 4 to 5 at 2 hours after operation,and was 0~3 at other time points.There was no significant difference among two groups in the VAS score.Conclusion Parecoxib can provid effective postoperative analgesia for patients underwent laparoscopic urological surgery as flurbiprofen.

OBJECTIVETo study the role of Mycobacterium tuberculosis in the pathogenesis of sarcoidosis.

METHODSArchival material of 22 patients with a histologic diagnosis of sarcoidosis were retrieved. Real-time fluorescent polymerase chain reaction (PCR) was used to detect DNA fragments of the complex-specific insertion sequence IS6110 of Mycobacterium tuberculosis in formalin-fixed and paraffin-embedded biopsy samples.

RESULTSAmong the 22 samples studied, Mycobacterium tuberculosis DNA was detected in 11 cases. The sequence of PCR amplified IS6110 DNA fragments completely matched with the related sequence in Mycobacterium tuberculosis gene.

CONCLUSIONSMycobacterium tuberculosis DNA is identified in a certain proportion of patients with a clinicopathologic diagnosis of sarcoidosis. Mycobacterium tuberculosis may be an important etiologic agent, at least in some of these patients.

Objectives To investigate the impact of ischemic preconditioning (IPC) on dynamics of homing of endothelial progenitor cells (EPCs) after renal ischemia reperfusion injury (IR).Methods Sixty male Sprague-Dawley rats were randomly divided into three groups after right-side kidney nephrectomy:for sham-operated rats,lumbotomy without vascular clamping was performed; IR rats were clamped renal blood vessels for 40 minutes while IPC rats were pre-treated with 15 min ischemia and 10 min reperfusion.At 3,12,24 h,and 3 days after reperfusion,the pool of circulating,kidneys,lungs and spleens were harvested.The extent of renal injury was assessed by biochemical and histological examination.The dynamics of homing of EPCs was observed by flow cytometry.Results The rats in IPC group exhibited significant improvements in renal function and morphology.Compared with IR group and sham group,the number of EPCs in blood was increased in the IPC group at 12 h and 24 h after reperfusion (P ＜ 0.05).The number of EPCs in kidney was increased at all times pointin the IPC group and IR group as compared to the sham group (P ＜ 0.05.In addition,EPCs number was increased in IPC group compared with the IR group at 12 h and 24 h [(11.36±0.66)％ vs (6.37±0.69)％,(6.31±0.70)％ vs (4.40±0.60)％,all P＜ 0.05].Compared with IR group and sham group,the number of EPCs in the lung was increased in the IPC groups at 12 h after reperfusion [(2.95±0.66)％ vs (1.78±0.59)％,(1.66±0.61)％,all P ＜ 0.05].The number of EPCs in spleen was increased in the IPC group at 72 h as compared with the IR group and sham group [(0.55±0.06)％ vs (0.34±0.07)％,(0.31±0.06)％,all P ＜ 0.05].Conclusions Endogenous EPCs may home to injured kidney after IPC.EPCs can also gather in the lungs and spleen.

Objective To observe the variations in intraocular pressure(IOP)in vocal cord polyp resections supported by pedestal Iaryngoscope with Tono-Pen tonometer.Methods The IOP of patients (grade Ⅰ-Ⅱby ASA)who underwent vocal cord polyp resections supported by pedestal laryngoscope were detected by Tono-Pen tonometer 5 minutes later on supine position before the operation(T1),5 minutes later on cervical hyperextension position before the operation(T2),5 minutes later on cervical hyperextension position after the operation(T3),5 minutes lateron supine position after the operation(T4),20 minutes later on supine position after the operation(T5)after general anesthesia respectively.At each point the changes of mean arterial pressure(MAP),heart mte(HR),end-tidal carbon dioxide partial pressure(PETCO2),and airway pressure(PAW)were observed as well.Results There were no differences in MAP,HR,RETCO2,PAW at each point statistically.The IOP increased significantly at T2,T3,T4 compared with IOP at T1[(19.0±1.8),(25.7±1.9),(17.8±1.9)mm Hg(1 mm Hg=0.133 kPa)vs(11.9±1.7)mm Hg](P＜0.05).The differences between IOP at T2 and T3 were manifest(P＜0.05).So it Was the situation when the IOP at T3 and T4,T4 and T5 were compared(P＜0.05).The IOP at T5 was(12.1±1.5)mm Hg,there was no difference compared with T1.Conclusion The IOP increases gradually from the point when the patient put on cervical hyperextension position before the operation after general anesthesia and achieves the summit when the patient put on cervical hyperextension position after the operation,finally,decreases back to the preoperative level when the patient put on supine position after the operation.

Objective To improve detectable rate of gastric schwannoma by endoscopic ultrasonography (EUS). Method Clinical data and endoscopic ultrasonography (EUS) imaging features of 4 cases were retrospectively ana-lyzed which diagnosed as gastric schwannoma pathologically and immunohistochemically while diagnosed as gastric stromal tumor by EUS from May 2008 to June 2015 and reviewed the literature. Results 4 cases of gastric schwan-nomas are female and benign, all 4 lesions are solitary, 3 in gastric body, and 1 in fundus by endoscopic. By EUS, all lesions are originated from muscularis propria, hypoechoic change, even echoes and clear board without calcifica-tion or cystic changes. 2 cases have halo artifacts around the lesion. Literature review found that gastric schwannoma tended to occur in female, halo artifacts could be the feature of gastric schwannoma, calcification or cystic changes were rare in gastric schwannoma which were common in gastric stromal tumors. Conclusion It was difficult to distin-guish gastric schwannoma and gastric stromal tumors that originated from muscularis propria by EUS. For female patients with lesions originated from muscularis propria, originated from muscularis propria and occurred in gastric body, it was necessary to observe lesions whether there was being calcification or cystic and halo artifacts. Integrated all these performance, we should be in consideration of gastric stromal tumors, meanwhile, excluding the possibility of gastric schwannoma.
