Objective To observe the therapeutic effects and toxicities of bone marrow-sparing intensity-modulated radiation therapy (BMS-IMRT) for postoperative cervical cancer.Methods From January 2011 to June 2012,totally 70 postoperative patients with cervical cancer were divided into BMS-IMRT group with 34 cases and IMRT group with 36 cases randomly.External whole pelvic intensitymodulated irradiation combined with chemotherapy was carried out for all patients.The planning target volume received a dose of 45 Gy/25 fractions in all patients.Delineation of the pelvis and limitation dose were carried out in BMS-IMRT group:the pelvis V30 ≤ 50％.All cases received chemotherapy with cisplatin (40 mg/m2) once a week concurrently with radiotherapy.Results Treatment was completed in 67 patients,as the other 3 patients stopped chemotherapy because of myelosuppression.There was no statistically significant differences between two groups for the 2-year local control survival(LCS)and overall survival(OS),alimentary tract toxicity and urinary toxicity.IMRT group had more serious hematologic toxicity than BMS-IMRT group,with statistically significant difference (x2 =14.355,P ＜ 0.05).Conclusions The postoperative cervical cancer patients with poor prognostic factors who undergo concurrent chemoradiotherapy,IMRT group has more serious hematologic toxicity than BMS-IMRT group.The short-term effect and other toxicities reaction are similar between two groups.

Objective To study the function difference of T helper cells(Th)and dendritic cells (DCs) in patients with different hepatitis B virus (HBV) genotypes. Methods IL-12,IL-2 and IL-4 released by Th was measured in 30 patients with different HBV genotypes. After DCs were differentiated and proliferated, DCs’ configuration and amounts were observed, and IL-12 released by DCs was measured in 20 patients. Then the data were statistical analyzed. Results IL-12, IL-2 and IL-4 were significantly higher in patients with hepatitis B than the controls (t=2.9272,t=2.7350,P

A retrospective study was conducted based on the clinical data of 15 choledocholith patients after Billroth-Ⅱgastroenterestomy who were treated with endoscopic retrograde cholangio-pancreatography (ERCP) through colonoscopy or duodenoscopy.It showed that choledocholith removed by colonoscopy for patients with Billroth-Ⅱ gastroenterestomy can achieve comparable therapeutic effect,but this method can reduce the operation difficulty,shorten the operation time and significantly increase the success rate.

Objective To study clinical application and complication of heavy silicon oil (Densiron68) in the treatment of traumat- ic proliferative vitreoretinopathy.Design Non-comparatives,retrospective case series.Participants Twenty patients with proliferative vitreoretinopathy resulting from ocular trauma were recruited,whose retinal detachment arising from inferior or posterior retinal breaks. Methods Heavy silicon oil was applied to patients during vitrectomy.Silicone oil or gas was applied to patients with redetachment after heavy silicon oil was removed.Main Outcome Measures The rate of retinal attachment,vision,intraocular pressure,inflammatory re- action of anterior segment and silicone oil emulsification period.Results The rate of retinal attachment with one operation using heavy silicon oil was 50%(10/20 eyes)and 15%(3/20 eyes)with further surgery.The average follow-up time was 3.90?1.41 months.At the end of the follow-up,all tamponade agents were removed in 50% patients.Patients' logMAR vision after the surgery was 2.19?0.86,which was better than before the surgery (2.63?1.00) (P=0.037).There was little evidence of high intraocular pressure,excessive inflammatory reaction of anterior segment and cornea endothelial cell damage,but cataract became more serious without exception.Emulsification rate was 100% and the average emulsification period was 2.18?0.87 months.Conclusions Heavy silicon oil tamponade in vitreoretinal surgery for traumatic proliferative vitreoretinopathy has good efficacy and relatively few complications.However,its emulsification period is relatively short,which may constraint its application to a certain extent.

OBJECTIVE: To investigate the efficacy and related factors of nasal surgery combined with upper air way radiofrequency ablation(RFA) for treatment of obstructive sleep apnea hypopnea syndrome (OSAHS) with chronic nasal blockage. METHOD: One hundred and three mild or moderate OSAHS patients with chronic nasal blockage were recruited, all cases had nasal surgery and upper airway RFA. All patients were evaluated by body mass index (BMI), Epworth sleep scale (ESS), snoring scale, and nocturnal polysomnography (PSG). Eighty-nine patients were reevaluated at least 6 months after surgery with the preoperative methods. RESULT: After operation, the apnea and hypopnea index (AHI) decreased from (18.67 +/- 9.48)/h to (9.22 +/- 7.18)/h; the lowest artery oxygen saturation (LSaO2) increased from (0.83 +/- 0.08) to (0.92 +/- 0.06); the Epworth sleep scale(ESS) decreased from (8.74 +/- 5.67) to (5.12 +/- 3.74); the snoring scale decreased from (7.16 +/- 2.85) to (3.56 +/- 2.26), the percentage of time with oxyhemoglobin saturation below 0.90 (CT90) decreased from (18.64 +/- 12.98) to (10.73 +/- 8.29). All of the differences were obvious (P<0.01). Success was defined as a postoperative apnea-hypopnea in dex < 10 events per hour and at least 50% less than the preoperative value. The surgical success rate was 75.3% (67/89). No major perioperative complications occurred. CONCLUSION Our findings suggest that nasal surgery combined with upper airway RFA can improve snoring and disease-specific quality of life in patients with anatomic na sal obstruction with mild or moderate OSAHS.

Objective: to observe the clinical efficacy of acupuncture on diabetic nephropathy.Methods: altogether 54 cases were randomly allocated into acupuncture group (30 cases) and control group of western medications (24 cases), the latter was treated with routine western medication, while the former was combined acupuncture based on routine western medication,and the treatment course of the two groups were both 30 days. Results: the effect of treatment group was superior to the control group (P＜0.05). Conclusion: acupuncture can improve symptoms of diabetic nephropathy, lower blood glucose, urine albumin, blood urine nitrogen,and creatinine and improve the function of kidney.

OBJECTIVE:To evaluate the abnormality in hematological system induced by antituberculosis drugs so as to promote the rational use of drugs in the clinic.METHODS:The 441 case reports on abnormality in hematological system induced by antituberculosis drugs retrieved from Chinese medical science periodicals from Jan 1990 to Apr 2007 collected in CHKD periodicals knowledge base in China hospital digital library were analyzed statistically.RESULTS:A total of 15 antibuberculosis drugs were involved in the ADR cases,leading the list were rifampicin,ciprofloxacin and isoniazide,which resulted in a total of 211 ADR cases.Leukopenia was the chief clinical manifestation.CONCLUSIONS:It is essential for clinical practitioners master the distribution patterns of ADR in hematological system caused by antituberculosis drugs so as to promote medication safety.

Objective To explore the effect of brain derived neurotrophic factor(BDNF) on the birth weight and the brain weight of newborn rats with intrauterine growth retardation(IUGR).Methods Female and male Sprague-Dawley rats were mated together and the vaginal plug formation after mating was for pregnancy diagnosis.The day when the plug was observed was considered day 1 of gestation.Then,the pregnant rats were divided into IUGR group and sham surgery group.On day 17 of gestation,the uterine arteries of pregnant rats in IUGR group were clamped for 30 min by blood vessel forceps after abdominal cavity with clamping blood uessels was opened.The pegnant rats in sham surgery group only had abdominal cavity opened without clamping blood vessels.Then the pegnant rats in IUGR group received 9 g/L saline(IUGR group) or BDNF 1 ?g injected in the rat through caudal veins for 5 days after surgery(BDNF intervention group).After vaginal birth,the weight of newborn rats and their brain weigh were measured and analyzed.Results Compared with the sham surgery group,the birth weight and brain weight of IUGR group group rats decreased by 24.9% and 17.3%,respectively,the results were significant(Pa
