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.

After the practical experiences were described in cultivating military aviation medical information research brand, providing selective dissemination of information in novelty assessment of military aviation medical literature , establishing the platform for pushing the aviation medical information , integrating the aviation medical resources , and carrying on the methodology research of aviation medical information, the successful results in reference service were summarized in novelty assessment of military aviation medical literature.

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 objectively evaluate the effectiveness of reminder system in reducing catheter-associated urinary tract infections.Methods Databases were electronically searched to collect the trials.According to the inclusion and exclusion criteria,the literatures were screened,the data were extracted and the methodological quality of the included studies was assessed.Then Meta-analysis was performed by using RevMan 5.0 software.Results A total of 10 literatures involving 5 662 participants were included.The results of Meta-analysis showed that the reminder system group was superior to the control group in decreasing the incidence rate of catheter-associated urinary tract infections,shortening the days of indwelling catheter,and there were statistical differences.Conclusions Reminder system can shorten the days of indwelling catheter,decrease catheter-associated urinary tract infections,

Peritumoral edema (PTE) of the metastasis tumor of brain (MTB) refers to the abnormal increase of moisture in the surrounding cerebral parenchyma of the brain tumor. The mechanism of PTE occurrence of MTB is complicated, and the influencing factors are diverse. PTE is one of the key factors that affect patient survival and cure. Researchers from China and overseas believe that it may be related to the expression of the vascular endothelial growth factor (VEGF) or VEGF receptor, aquaporin-4 (AQP-4), matrix metalloproteinase-9, interleukin-6, hypoxia inducible factor-1a, and other molecular biology factors. Studies of these molecular biologi-cal factors provide objective scientific evidence for the prevention, control, monitoring, treatment, and prognosis of PTE of metasta-sized brain tumor. In addition to the traditional dehydration therapy of PTE, the use of PTE-related molecular biological factors pro-vides a new approach for the treatment. AQP-4 agonists or antagonists and VEGF receptor antagonists also have good therapeutic poten-tials. In this paper, the authors reviewed the PTE-related molecular biological factors of MTB.
