1.Clinical study of breast-preserving surgery in breast cancer
International Journal of Surgery 2008;35(9):601-604
Objective To study the clinical effects of breast-preserving surgery in early-stage breast cancer. Methods From March 2002 to March 2007, 27 cases of early-stage breast cancer were treated with breast-preser-ving surgery. The control group had 28 cases, treated with radical mastectomy. Survival rate and recurrence rate were observed. Results The short-term progress of breast-preserving surgery in early-stage breast cancer had no significant difference with that of radical mastectomy. Plastic effects of breast were satisfied. Conclusion Breast- preserving surgery in early-stage breast cancer had favorable effects both in progress and in plastic. Therefore, it is warranted for wide use.

Objective To study the possibility of fetal cardiac rhabdomyoma diagnosed by ultrasonography,and the relationship between the fetal cardiac rhabdomyoma and family tuberous sclerosis. Methods High resolution ultrasonic equipment with fetal cardiac software was used. The main cross section of four chamber view was studied mainly. The location, the number of the tumor and the outflow tract of left and right ventricular cordis were scanned carefully, the maternal abdominal scan was performed as well. Results Five cases of fetal cardiac rhabdomyoma were found by routine prenatal ultrasonography, and were confirmed by autopsy. Among them, one case were associated with maternal tuberous sclerosis. Conclusions Fetal cardiac rhabdomyoma associated with tuberous sclerosis. Fetus with cardiac rhabdomyoma frequently die of cardiac failure; since the prognosis of the tuberous sclerosis with neural sclerosis was very poor, when the fetal cardiac rhabdomyoma was detected prenatally, the possibility of tuberous sclerosis should be considered, also relative examination must be performed to the mother to decrease the perinatal mortality.

Diabetic retinopathy ( DR ) is one of the main blinding eye diseases for people over the age of 50, and diabetic macular edema ( DME) is the leading cause of vision loss is DR patients. The early diagnosis and early treatment is important. As OCT and FFA, mfERG, especially the retinal thickness, volume, retinal edema index quantitative indicators such as objective evaluation of macular edema, embodies the new progress of retinal imaging technology in recent years. OCT is a non -contact clinical application in recent years, noninvasive, high resolution of ophthalmic imaging examination, can do it on retinal ultrastructure observation and quantitative analysis, and the technology is relatively mature, become a routine inspection diagnosis of macular edema. Laser photocoagulation, intravitreous injection with Ranibizumab and vitrectomy is nowadays the important means for the treatment of intractable macular edema.

Objective To study the preparation technique for Jiegeng Zaogan capsules (capsules of total saponins from the roots of Platycodon grandiflorum A.DC).Methods The optimal preparation technique for Jiegeng Zaogan capsules was investigated by L9(34) orthogonal test with the Platycodin D content as the observation index.Results The optimized extraction procedure was as follows:extracting for 3 hours each time and 3 times in total,adding 10-fold water,alcohol sedimentation concentration at 65 %,and alcohol sedimentation solution staying for 48 hours.Conclusion The preparation process of Jigeng Zaogan capsules is reliable with stable quality,which offers a feasible method for the industrialization production of the capsules.

Objective The microbiology specimen types were various and complex ,the system of main specimen types in micro-biological detection was established under the laboratory information system (LIS) for realizing the management target of quality control before microbiological analysis .Methods A total of 3304 submitted microbiological samples were collected from January 1 to 31 in 2015 .After setting the microbiological item application procedure of main specimen types in LIS ,1532 submitted microbio-logical specimens from June 20 to 24 were performed the statistics .The error rates of specimen types were compared before and af-ter setting .Then 1635 and 1340 submitted microbiological specimens were re-collected form July 9 to 13 and August 10 to 15 ;the change of error rates was continuously observed for comparing whether the statistical difference of error rates existing between be-fore and after setting .Results The error rate of submitted microbiological specimens before setting was 4 .6% (152/3304) ,which after setting was 1 .3% (20/1532)(χ2 =31 .224 ,P<0 .001) ,which during the continuous observation period maintained the lower level of 1 .04% (17/1635) ,χ2 =39 .658 ,P<0 .001) and 0 .9% (13/1340 ,χ2 =34 .673 ,P<0 .001) .Conclusion Re-setting the LIS reduces the error rate of microbiological specimen type ,effectively increase the working efficiency and reaches the quality control in-dex before microbiological analysis .

Objective To investigate the anticancer effects and molecular mechanism of betulinic acid (BA)on Raji cells in vitro.Methods The effects of BA on the growth of Raji cells were studied by MTT assay.Apoptosis was assessed by Annexin-V/PI double-labeled cytometry.The influence on cell cycle was studied by flow cytometer.The cyclin D3 mRNA expression was checked by Western blotting and RT-PCR techniques.Results BA showed obvious inhibition on proliferation,as well as induction potency of apoptosis on Raji cells in vitro in a time-and dose-dependent manner by Annexin-V/PI double-labeled method.With the IC_(50)value for 24 h being(39.44?0.65)?g/mL,Raji cells treated with BA showed ac- cumulation in G_0/G_1 phase and reduction in the percentage of cells in S phase.The cyclin D3 mRNA ex- pression and protein were sharply decreased in Raji cells treated with BA.Conclusion BA could inhibit the proliferation of Raji cells by regulating the cell cycle that arrests cells at G_0/G_1 phase and induces apop- tosis of Raji cells.The antitumor effects of BA may be related to down-regulation of the expression of cy- clin D3.

Objective To investigate the relationship between nonalcoholic fatty liver disease (NAFLD) and benign prostatic hyperplasia (BPH) in elderly patients.Methods 50 elderly BPH men with NAFLD were enrolled in this study,while 30 age-matched BPH men without NAFLD were selected as the control group.Prostate volume (PV),body mass index (BMI),triglycerides (TG),fasting blood glucose (FBG),fasting plasma insulin (FINS) and homeostasis model of assessment for insulin resistanceindex (HOMA-IR) were compared between the two groups,and correlations of PV with FINS and HOMA-IR were analyzed in the NAFLD patients.Results The PV level was significantly higher in NAFLD patients than in control group [(48.2±16.3) ml vs.(33.2± 11.5) ml,P<0.01].The incidence of severe BPH was higher in NAFLD group than in control group (42.2% vs.13.3%,P<0.05).BMI,TG,FBG,FINS and HOMA IR were higher in NAFLD group than in the control group (all P<0.01).The PV was positively correlated with FINS and HOMA-IR levels in elderly NAFLD patients (r=0.814,0.601,respectively,both P< 0.01).Conclusions NAFLD is closely associated with BPH in elderly males,and NAFLD may be one of the risk factors for BPH.

Objective:To evaluate the vestibular function of motion sickness. Method:VNG, which tests the vestibular function of horizontal semicircular canal,and CPT, which tests vestibulospinal reflex and judge proprio-ceptive,visual and vestibular status, were performed in 30 motion sickness pations and 20 healthy volunteers(control group). Graybiel score was recorded at the same time. Result:Two groups' Graybiel score (12. 67±11. 78 vs 2. 10±6. 23;rank test P<0. 05),caloric test labyrinth value [(19. 02±8. 59)°/s vs (13. 58±5. 25)°/s ;t test P< 0. 05],caloric test labyrinth value of three patients in motion sickness group exceeded 75°/s. In computerized pos-tourgrphy testing(CPT) , motion sickness patients were central type(66. 7%) and disperse type(23.3%);all of contral group were central type. There was statistical significance in two groups' CTP area, and motion sickness group was obviously higher than control group. While stimulating vestibulum in CPT, there was abnormality (35%-50%)in motion sickness group and none in contral group. Generally evaluating CPT,there was only 2 pro-prioceptive hypofunction,3 visual hypofunction, and no vestibular hypofunction, but none hypofunction in contral group. Conclusions Motion sickness patients have high vestibular susceptible, some with vestibular hyperfunction. In posturography,a large number of motion sickness patients are central type but no vestibular hypofunction, but it is hard to keep balance when stimulating vestibulum.
