Objective To assess the clinical significance of the expression of p53, p21 protein in breast cancer (BC). Method The expression levels of p53, p21 proteins were examined by immunohistochemical (IHC) SP techniques in 69 BC specimen and 20 paracancinoma breast tissue. Result p53 and p21 proteins were failed to be observed in the paracancer tissue. p53 protein was found in 47.8% of BC, while p21 protein in 43.5% of BC. Along with the declined of BC cell differentiation degree, p53 expression increased significantly and p21 expression declined obviously. Expression of p21 was lower in patients with lymph node metastasis than that in patients without lymph node metastasis (P

Objective To investigate the clinical value of substitute popliteal vein valve operation (SPVSO) for primary lower limb deep vein insufficiency(DVIS). Methods The clinical data of 859 cases(907 legs) of DVIS who underwent SPVSO in the past 10 years in our hospital were analyzed retrospectively. Results Symptoms of edema and fatigue distinctly reduced or disappeared after the operation.Pigmentation in the lower portion of the leg began to disappear in 1 week, and nearly or totally disappeared within 2 weeks after the operation.Ulcer in the lower portion of the leg recovered three weeks after the operation. Patients were followed up for 6 to 120 months. The effective rate within 60 months was 96.8%, and the effective rate over 60 months was 87.2%. Conclusions The curative effect of SPVSO on primary deep vein insufficiency of lower extremity is definite and it is worthy to be clinical practice.

Glutamine is not only a special nutritional substance but a conditional essential amino acid,which is the most abundant amino acids in plasma,representing about 60％ of free amino acids in the body,and it's normal plasma concentration is from 0.6 to 0.9 mmol/L.In recent years,with the increasing deepening study of the field of clinical nutrition,the concept of glutamine study has been gradually changed gradually changed it's concept from a simple nutritional support to immune nutrition therapy.Glutamine can not only improve the body's protein levels of nutrition,protect the gastrointestinal mucosa,but also reduce the incidence of infection and the inflammation in the body,improve immune function,reduce side effects of chemotherapy,and at the same time enhance tumor sensitivity to chemotherapy and promote gastrointestinal cancer patients' postoperative recovery,reduce surgical complications.This paper aims to review the application and research of glutamine in the gastrointestinal cancer patients after the operation.

Objective To discuss the correlationship between the diagnosis of surgical pathology and the signs of malignancy which is both displayed by breast conventional mammography and amplificatory mammography with partial compression.Methods 65 cases with breast cancer were examined by both breast conventional mammography and amplificatory mammography with partial compression.The results of the two methods were analyzed.Results In all 65 cases of breast cancer,the comparison between breast conventional mammography and amplificatory mammography with partial compression could provide 16/60 cases in the X-ray signs of malignancy,which were in accordance with pathological examination results,19/41cases in the occurrence of calcification,13/37 cases in ductal calcification,0/4 cases in mixed type calcification,18/46 and 14/59 cases in the occurrence of lobulation and spicule signs.Conclusion Amplificatory mammography with partial compression can provide better insight in breast cancer than conventional mammography,especially in the region of dense shadow,small calcification and dense breast lesions,amplificatory mammography with partial compression can provide higher accuracy in diagnosis,especially for early breast cancer.

Background Carbachol solution (0.01％) is an agonist of M cholinoceptor and skeletal muscle N cholinoceptor,and it is used to play miotic effect and open peripheral iridectomic hole during the surgery of implantable collamer lens (ICL) implantation in order to lower intraocular pressure (IOP).However,the anterior chamber injection of 0.01％ carbachol solution often causes relevant complications,while whether lower dose of carbachol solution is effective and safe is unclear.Objective This study was to compare the effectiveness and safety between 0.01％ carbachol solution and 0.005％ carbachol solution after anterior chamber injection during the ICL implantation.Methods One hundred and fifty-two eyes of 76 cataract patients were included in Daping Hospital of Third Military Medical University from September 2014 to September 2015.ICL implantation and periphery iridectomy were carried out on both eyes of the patients and the 0.01％ carbachol solution was injected into the anterior chamber during the surgery of the right eyes and 0.01％ carbachol solution was used in the left eyes.The operation duration and IOP at postoperative 2 hours and systemic choline-like reaction were compared between 0.01％ carbachol solution group and 0.005％ carbachol solution group.Results The mean operation duration was (11.86± 2.39) minutes and (11.22 ± 1.85) minutes in the 0.01％ carbachol group and 0.005％ carbachol group,without significant difference between two groups (t =1.851,P =0.066).IOP was (15.76 ± 2.18) mmHg and (13.58 ±2.24)mmHg in the 0.01％ carbachol group before and after surgery,and those in the 0.005％ carbachol group was (15.70±2.35)mmHg and (13.12±2.17)mmHg,there was no significant difference in the IOP between the two concentrations of carbachol (Fsroup =0.986,P=O.322).The IOP at postoperative 2 hours was lower than that before operation,the difference was statistically significant(Ftime =97.339,P =0.000).There was no interaction between drug concentration and time (Fcorrelation =0.772,P =0.381).The incidences of complications,such as dizziness,nausea and vomiting,were lower in the 0.005％ carbachol group than those in the 0.01％ carbachol group (x2 =13.01,5.16,4.03,all at P＜0.05).Conclusions Carbachol solution (0.005％) can play intraoperative miosis effect and maintain effective operation duration in ICL implantation.In addition,the application of 0.005％ carbachol solution is quite safe in both intraoperation and postoperation.

Objective To analyze the correlation between non-motor symptoms (NMS) and the quality of life in the mild Parkinson's disease (PD) patients of different genders.Methods 85 mild PD patients (H-Y stage 1～2) were investigated.The PD NMS Quest was used to assess NMS.The quality of life was assessed with SF-36 questionnaire.Results Stepwise linear regression analysis showed that nocturia,restless legs,depression,daytime sleepiness,decreased interest,smell taste problems were positively correlated with the score of life quality of male and pain,increased sweating,taste smell problems,sleep problems,changes in libido,decreased memory,diplopia influenced life quality score of female.The scores of SF-36 questionnaire of the male with PD were lower than that of female patients.Conclusions The nonmotor symptom (NMS) There was a gender difference about the influence that NMS has made on PD patients.The male's life quality were lower than that of female patients about mild PD patients.

Gastrointestinal stromal tumors are the common mesenchymal tumors of the gastrointestinal tract. The constitutive activation of KIT is one of the earlies ttransforming events in GISTs and occurs mainly through activating mutations in the kit gene. PDGFRa is associated with the pathogenesis of GISTs too. The main mutative site of KIT gene are exon11, exon9, exon13 and exon17 and those of PDGFRA are exon18, exon12 and exon14.The clinical parameter and the response to imatinib of GISTs are associated with the site and type of gene mutation. Imatinib mesylate is a small-molecule inhibitor that selectively inhibit the tyrosine kinase and the clinical use of it is one milestone of the targeted therapy of GISTs. We review the gene mutation and targeted therapy development of gastrointestinal stromal tumors in this article.

ObjectiveTo observe the effect of Integrated Traditional Chinese and Western Medicine on primary trigeminal neuralgia. Methods126 cases with primary trigeminal neuralgia were divided into treatment group (63 cases) and control group (63 cases), who accepted Integrated Traditional Chinese and Western Medicine and western medicine only. They were assessed with Chinese version McGill Pain Questionnaire before and after treatment, and followed up for 1 year. ResultsThe incidence of cure in treatment group was higher than that of control group (P<0.05), and the relapse was reduced (P<0.05). ConclusionThe Integrated Traditional and Western Medicine is more effective on primary trigeminal neuralgia, and reduce the relapse.

AIM: To investigate the influences of microRNA-126 on the curative effect of chemoradiotherapy and radiosensitivity of SGC-7901 cells.METHODS: The patients of gastric cancer (n=60) were selected in this study including 32 males and 28 females with the average age of (51±7) years.All patients received similar chemoradiotherapy strategy.The tissue and blood samples were collected during treatment.The short-term curative effect was evaluated by the Response Evaluation Criteria in Solid Tumors (RECIST), and the patients were divided into sensitive group and insensitive group.The microRNA-126 levels were detected by RT-qPCR.The SGC-7901 cells were maintained in vitro and transfected with microRNA-126 mimic.The plate colony formation assay was used to determine the enhancement effect of microRNA-126 on radiosensitivity of the SGC-7901 cells.The apoptotic rate of the SGC-7901 cells induced by microRNA-126 was analyzed by flow cytometry.RESULTS: According to the RECIST, 28 cases were defined as sensitive patients and 32 cases were the insensitive patients.Compared with the sensitive patients, the microRNA-126 levels both in blood and tissue samples were lowered in the insensitive patients, and the relative fold changes were 0.72±0.04 and 0.48±0.03, respectively (P<0.05).After transfection with microRNA-126 minic, the SF2 and D0 in the SGC-7901 cells were decreased with the SER of 1.74.Furthermore, microRNA-126 induced apoptosis of SGC-7901 cells and enhanced their radiosensitivity.CONCLUSION: The patients with low microRNA-126 level may suffer a poor curative effect of chemoradiotherapy on the gastric cancer.MicroRNA-126 has an enhancement effect on the radiosensitivity to the SGC-7901 cells.

Objective To validate the molluscicidal effect of magnesium borate ore powder (MBOP), and explore the mechanism for providing the scientific basis for the field use. Methods The experiments were performed by the Copper Coin method, Volatilization method and Immersion and Sprinkle methods recommended by WHO. Results The MBOP can't kill the snail by the volatilization. The molluscicidal effect was well by the Immersion and Sprinkle methods. The acted effect was quick by using the Immersion method while the effect was more stable by using the Sprinkle method.LD_(50) of the Sprinkle method (27℃,4 days) was 4.07 g/m2. Conclusion MBOP's molluscicidal effectiveness is well, the action appears gradually and the effect is stable. The possible mechanism of MBOP might act through some dissolved components.
