Objective: To evaluate the efficiency and safety of ibandronate at the initial loading dose in the treatment of metastatic bone pain (MBP) induced by non-small cell lung cancer (NSCLC). Methods: Thirty cases of NSCLC patients who were admitted to our hospital from May 2006 to July 2007 were retrospectively analyzed. They received loading dose of ibandronate for MBP treatment. Ibandronate was given to the patients intravenously at initial loading dose of 6 mg for more than 15 min on 3 consecutive days. Then ibandronate was administered repeatedly at 6 mg every 3 to 4 months. The response time, pain score, QOL score, daily morphine consumption dose were recorded. The serum markers such as calcium, creatinine, alkaline phosphatase (AKP) were monitored. Results: Twenty nine cases were eligible to evaluate the efficiency and safety. Among them, the MBP of 25 cases (86.2%) were relieved. Their average response time was 2.9 ± 0.8 days. The pain score was significantly decreased after treatment and the life qualities of patients were markedly improved (P <0.001). The morphine consumption dose was reduced by about 20 to 40 mg in 4 cases after treatment. The serum calcium level increased in 7 patients before treatment and declined to the normal level after treatment. The adverse reaction was relieved after treatment and no renal toxicity was observed. Conclusion: Administration of ibandronate at initial loading dose had quick on-set and mild side effects. It could significantly relieve metastasis bone pain and improve QOL, reduce the morphine consumption dose and avoid morphine-induced adverse reaction, and effectively decrease serum calcium level. Administration of ibandronate at initial loading dose is a new promising option for treatment of the MBP in NSCLC.

OBJECTIVETo observe the immediate analgesic effect of tendon acupuncture on soft tissue injury in different sites.

METHODSA total of 140 cases of soft tissue injury, involving 14 injury sites, were treated with tendon acupuncture. According to the principle of "considering pain as acupoint", based on injury sites, one to three tendon acupoints were selected in each tendon, which were treated with 1 to 5 times. Totally 676 times Of treatment was given. The visual analogue scale (VAS) was used to evaluate the immediate. analgesic effect before and after the treatment.

RESULTSAfter the treatment, the score of VAS was significantly reduced (4. 20+ 1. 77 vs 2. 43 ± 1. 30, P<0. 001); regardless of the total number of treatment, the score of VAS after each acupuncture was obviously reduced compared with that before acupuncture (all P<0. 001); the score of VAS at each injury sites after treatment was significantly reduced compared with that before treatment (all P<0. 001).

CONCLUSIONThere is an immediate analgesic effect of tendon acupuncture for different sites of soft tissue injury. Also, the effect has been shown in different frequencies of treatment.

Drug-induced nephrotoxicity is very common in both new drug development and clinic practice. Various drugs can induce kidney injuries, including tubulointerstitial, glomerular and renal vascular disease. To investigate the mechanism of drug induced nephrotoxicity is important for risk reduction of new drug development, reasonable drug usage, early discovery and effective prevention/treatment of adverse effects in clinics.

OBJECTIVE:To optimize the formulation of Asiaticoside cationic liposomes,and to investigate the characteristics of drug release in vitro. METHODS:The thin film dispersion method was used to prepare liposome;using encapsulation efficiency and drug-loading amount as index,the formulation of Asiaticoside liposomes was optimized by central composite design-response surface method with the ratio of drug to lipid(X1),the ratio of cholesterol to lipid(X2)and the concentration of D-mannose(X3) as factors. Using sodium lauryl sulfate as medium,in vitro release characteristics of cationic liposomes prepared with 1%octadecyl-amine was investigated by bag filter method,and compared with those of Asiaticoside solution and common liposome. RESULTS:The optimal formulation was X1 0.07,X2 0.17 and X3 0.03 g/ml. The encapsulation efficiency was (75.529 ± 1.071)%,and drug-loading amount was(2.539±0.029)%(n=3);the deviation from the predicted values were -0.217% and 0.205%;1% oc-tadecylamine was add into formulation to obtain cationic liposomes,and the Zeta potential had changed from -5.6 mV to 20.8 mV. in vitro accumulative release rates of Asiaticoside solution,common liposomes and cationic liposomes were 89.13%(12 h), 87.58%(72 h) and 94.46%(72 h),and the latter was in line with Weibull model. CONCLUSIONS:Asiaticoside cationic lipo-somes have high encapsulation efficiency,and can releases for 72 h.

Purpose:Discuss the clinicat value of video-mediastinoscopy in the diagnosis and treatment of intrathoracic diseases. Methods:From Oct.2002 to Jun.2003, 58 cases were examined and treated by video-mediastinoscopy. Of these patients,48 case were examined(the examination group) and 10 cases were treated(the treatment group). In the examination group, standard mediastinoscopy was applied in 40 cases, extended mediastinoscopy was applied in 8 cases. In the treatment group,9 cases of palmar hyperhidrosis were treated by thoracic sympathectomy,1 case of pericardial liparomphalus was resected. Results:In the examination group, 47 cases obtained definite pathological diagnoses, and 5 cases had complications. In the treatment group,no complications occurred. Conclusions:Video-mediastinoscopy is a valuable procedure to clarify diagnosis and to stage lung cancer, or in the diagnosis of mediastinal mass. It can also be used in the treatment of palmar hyperhidrosis, pericardial liparomphalus and pericardial cyst.

65 years) with acute cholecystitis treated by PTGBD in this hospital between January 2001 and December 2005. All the patients were not symptomatically relieved after conservative therapy and/or had severe accompanying co-morbidities. Results A successful tube insertion was achieved in 29 patients, whereas insertion failure was encountered in 1 patient because the gallbladder was full of stones, in which a bile aspiration was performed. The dislodgement of drainage tube occurred in 2 patients (one patient underwent a re-insertion and the other was symptomatically relieved without insertion). Exacerbation of the condition developed in 1 patient after the treatment, and an open cholecystostomy with abdominal irrigation and drainage was performed. Twenty-seven patients were discharged from hospital with the drainage tube intact. Of them, the drainage tube was removed 3 weeks after PTGBD in 25 patients, was maintained for 8 weeks until surgery in 1 patient, and was dislodged in 1 patient. Twenty-eight patients with calculous cholecystitis underwent a delayed surgery, including LC in 25 patients, stone removal by choledochofiberscope in 2 patients, and open surgery in 1 patient because of accompanying choledocholithiasis and retroperitoneal mass (adrenal tumor). In another 4 patients with choledocholithiasis, an intraoperative choledochofiberscopy during LC was performed in 2 patients, and endoscopic sphincterotomy after LC was conducted in 2. No surgery related deaths or bile duct injuries occurred. Conclusions Combined use of PTGBD and delayed LC in elderly patients with acute cholecystitis is safe and effective.

Objective The clinical effect of phacoemulsification and intraocular lens implantation in the treatment of senile cataract.Methods120 cases of senile cataract patients in September 2014 ~2016 year in December in our hospital, were randomly divided into two groups: the observation group after phacoemulsification combined with intraocular lens implantation, the control group was treated with small incision non phacoemulsification extracapsular cataract extraction.In the comparison of two groups.ResultsAfter treatment, the observation group was 0.5~0.9 the proportion of 51.7%, visual acuity>1 the proportion of 6.7% were significantly higher than control group (P<0.05);the complication rate of observation group was 43.3% lower than the control group 61.7%, the difference was statistically significant (P<0.05).ConclusionPhacoemulsification combined with intraocular lens implantation in senile cataract patients can effectively improve patients' visual acuity, control the occurrence of complications, and the prognosis is good.
