Objective:To explore the reversal effect of Docetaxel and Capecitabine on rat breast precancerous from angiogenesis and expression of related regulatory factors VEGF mRNA in rats.Methods: 350 SD rats were divided into 7 groups.Model of rats mammary was induced by DMBA and was treated by Docetaxel and Capecitabine for 4 weeks.All of them were killed from 8th week.The microvascular were detected in the specimens, examination of histopathology was performed and the expression of VEGF mRNA was measured by in situ hybridization.Results:The rat mortality and the incidence of precancerous lesions increased obviously, and the incidence of precancerous lesion of the high-dose group and the middle dose reduced.The positive rate of the expression of MVD,TGF-αand VEGF mRNA tend to increase in all the groups.The positive-cell rate of VEGF mRNA of Docetaxel,Capecitabine, Docetaxel and Capecitabine in ADH was lower than in the model group,and the positive-cell rate of VEGF mRNA of Docetaxel and Capecitabine was lower than Capecitabine and Docetaxel separately.Conclusion: Combination of Docetaxel and Capecitabinecan decrease the expression of VEGF mRNA in precancerouslesion of rats mammary.

With the deepening of the reform of medical system in China and the transforma-tion of modern medical model , cultivating graduates with community service ability is an important task of medical education at present. Through practice activities by forming an undergraduate medical service team, such as community residents health survey, free clinics, health care propaganda, will enhance the students' sense of responsibility and community identity, cultivate their clinical and sci-entific thinking ability and enhance their self-confidence, self-study ability, communication skills and comprehensive quality. It will also promote the community residents to improve the level of health.

OBJECTIVE:To provide reference for rational use of antibiotics in patients with AECOPD. METHODS:The patho-gen distribution and antibiotics use of AECOPD patients was analyzed in respiratory department of our hospital during 2014-2015. The infection site,pathogen distribution and antibiotics use(including medication purpose,drug name,usage,dosage,medication duration,route of administration,drug combination),infection and compliance were investigated and analyzed statistically. RE-SULTS:Among 967 AECOPD patients,there were 619 cases of positive sputum culture(64.01%). A total of 774 strains were iso-lated,including 542 strains of Gram-negative bacterial (70.03%) and 232 strains of Gram-positive bacterial (29.97%);most of them were Pseudomonas aeruginosa(207 strains,26.72%). 765 patients were treated with antibiotics,and utilization ratio of an-tibiotics was 79.11%. 276 cases were treated with one kinds of antibiotics (36.08%),435 treated with 2 kinds of antibiotics (56.86%)and 54 treated with 3 kinds of antibiotics and above(7.06%). Top 3 drugs in the list of frequency were Levofloxacin injection(455 cases/times,47.05%),Moxifloxacin injection(241 cases/times,24.92%)and Cefmetazole for injection(192 cas-es/times,19.86%). Top 3 drug combination regimen were Cefmetazole for injection+Levofloxacin injection (107 cases/times, 21.88%),Cefoxitin for injection+Levofloxacin injection(96 cases/times,19.63%)and Moxalactam for injection+Levofloxacin in-jection(65 cases/times,13.29%). CONCLUSIONS:Anti-infective therapy regimen of AECOPD patients should be formulated ac-cording to relevant guideline,and pathogenic factors of infection are analyzed. Great importance should be attached to reasonable, scientific,safe and standard use of antibiotics,etiological examination;pathogenic bacteria culture and drug sensitivity test should be conducted as soon as possible. So as to obtain better therapeutic efficacy and reduce the generation of drug-resistant strain.

Objective:To study the relationship between TCM constitution and differentiation of signs and symptoms for syndrome classification in patients with psoriasis vulgaris.Methods:According to associated standard in traditional and western medicine,psoriasis vulgaris patients were identified,the syndrome differentiation and PASI were performed.Results:Among 97 cases of psoriasis vulgaris,blood-heat syndrome was 45.4%,blood-dryness was 29.9%,blood stasis was 24.7%,the PASI of blood-heat was significantly more than that of blood-dryness(P

By employing the methods of literature research and specialist consultation,comprehensively and systematically collected case history at home and abroad on Chinese and western medicine in the treatment of AIDS,by distilling the etiopathogenisis and pathogenesis,the character,the clinical stage,TCM four methods of examination,di erentiation of symptoms,the therapeutical principle and method and the e ective prescription,etc,the paper clari ed the character,pathology,etiology and pathogenesis of AIDS by the evaluation and statistic of qualitative and quantitative analysis of evidence based medicine,grasped the present situation of the treatment of AIDS with Chinese and western medicine in the treatment of AIDS,the rule of syndrome di erentiation and the facticity and application of the clinical e cacy.All these are used to the TCM handbook of AIDS diagnosis and treatment.

Objective:To investigate varied electromyographic types in the patients with hemimasticatory spasm(HMS).Methods:Surface electromyography was recorded to study electromyographic features of 16 cases with HMS.Results:Spasm was found in mandibular rest position in 2 cases and in tooth contact position in 14 cases.During the involuntary spasm of the 14 cases, motor unit potential could be classified into three types:continuous(8 cases), rhythmic(3 cases) and irregular(3 cases).Conclusion:The electromyographic feature of hemimasticatory spasm is characterized by continuous motor unit potential discharge. The spasm is mostly triggered by tooth contact.

ObjectiveTo improve an obvious postoperative man-made crease when eyes closed and to achieve the optimal cosmetic and functional results.MethodsExposing and scissoring the levator aponeurosis were performed to make it move freely.Fairly infra-incision and lower margin orbicularis oculi muscle were cut.The double eyelids were formed by fixing the palpebral dermis of the lower skin flap onto the levator aponeurosis.ResultsThe follow-up of 580 patients (1160 eyes) showed that double eyelid crease were natural and fluent,eyelashes raised slightly,there was no an obvious postoperative man-made crease when eyes closed,and there was no sausage-appearing. Conclusions The method is quick,with minor injury and fast restoration. There is no sausage appearance and an obvious man-made crease when eyes are closed,and so double eyelids are natural and nice,the postoperative results are all aesthetically and functionally pleased.

ObjectiveTo observe the clinical effect of laparoscopic intrafascial supracervical hysterectomy.Methods The complications during and after the operation of laparoscopic intrafascial supracervical hysterectomy of 46 patients were reviewed and summarized retrospectively. Results Laparoscopic intrafascial supracervical hysterectomy of 46 cases had been done well without significant complications,such as injury of intestine,bladder and ureter.Four cases had complications in short term,one was pelvic hematoma,one was pelvic infection,and two were hematocele in cervical canal.There were five cases had complications in long term.Residual cavity periodic hemorrhage in two cases,cervical gland cyst,pelvic parcel effusion and cervical polypoid hyperplasia each in one case.ConclusionsThere are less complications during the laparoscopic intrafascial supracervical hysterectomy,while much more after the surgery.Therefore,the surgical method needs to be improved.

Objective To assess the clinical application value of color Doppler ultrasound guided puncture in peripherally inserted central catheter (PICC). Methods Thirty-two patients needed long-term intravenous infusion underwent PICC. Color Doppler ultrasound was used to select the puncture vascular,the best puncture point and angle, and the entire process was monitored and guided dynamically, and the initial position of the catheter tip was located. Results Color Doppler ultrasound-guided puncture was successful in all 32 patients, and the successful rate was 100%. The guided puncture time was 22 s to 19 min, and the first puncture succeeded in 30 patients (93.75%). Conclusion Color Doppler ultrasound-guided puncture in PICC can obviously raise the success rate of puncture, shorten puncture time and reduce the complications. It is an easy, safe and certain method.
