Objective To investigate the value of ultrasound-guided Mammotome minimal invasive system in the treatment of breast fibroadenoma.MethodsFrom January 2007 to October 2008,266 benign breast lesions of 183 cases were treated by ultrasound-guided Mammotome minimal invasive system.The diameter of the masses ranged from 4 to 25 mm(≤ 10 mm in 73 cases,10-20 mm in 148,and ≥ 20 mm in 45).ResultsThe 266 lesions in the 183 patients were excised completely by using the Mammotome system.The excision was performed for a mean of 15 times in each case(ranged from 5 to 44 times) with an average operation time of 26 minutes(10 to 60 minutes).No complication was found after the surgery except slight subcutaneous ecchymosis in 2 cases.The length of the incisional scar,which was not apparent,ranged from 2.5 to 4 mm.The 183 cases were followed up by ultrasonography for 2 to 22 months(mean,12 months),during which their BI-RADS scales ranged from Ⅰ to Ⅱ,no local recurrence was found.ConclusionsUltrasound-guided Mammotome minimally invasive system is feasible for total resection of breast fibroadenoma with appropriate sizes.The technique leads to fewer complications and good cosmetic results.Further studies on the system are necessary for the treatment of multiple breast fibroadenomas.

The present study is designed to investigate the histochemical changes of cholinesterase, norepinephrine in nuc. Supraopticus and locus coeruleus of rats following electo-acupuncture and their possible relation to pain threshold. The preliminary results indicated that the elevation of pain threshold following electro-acupuncture concomittantly with increase in histochemical reaction of cholinesterase, and norepinephrine both in nuc. Supraopticus and locus coeruleus of electro-acupunctured rats. The increase in intensity was shown to be correlated with the elevation of pain threshold. The intensity of increased cholinesterase activity was more obvious in the animals with pain threshold elevated for above two folds than those elevated only one fold. On the other hand, the higher intensity of norepinephrine was obser ed in locus coeruleus with one fold of elevation of pain threshold. The significance of the changes in these two nuclei and their possibld function were briefly discussed.

OBJECTIVE To explore the risk factors in aged patients with ventilator-associated pneumonia(VAP) and to provide the corresponding clinical prevention strategies. METHODS The ages,underlying diseases,mechanical ventilation method,use of antibiotics,and pathogenic bacteria of the VAP patients were investigated and analyzed. RESULTS Totally 155 VAP of elderly patients had serious underlying diseases,and treated with broad-spectrum antibiotics,tracheal intubation or trachea incision.Most pathogenic bacteria were mutiple-resistant. CONCLUSIONS The prevention of VAP was in priority for control of VAP patients.In order to control the occurrence and spread of VAP,clinicians should cut the time of ventilator,pay more attention to sterilization and isolation,and strengthen the tend of the patients.

OBJECTIVE To study drug resistance status of infected bacteria in abdominal surgical wound for their countermeasures. METHODS The abdominal surgical infection of a hospital was investigated from Jan 2000 to Dec 2004.Bacterial isolation and identification were carried out complying with National Operation Procedure of The Clinical Laboratory.Drug sensitivity test was performed with KB method. RESULTS The infection rate was 4.1%.The species were predominated by Gram-negative bacilli(71.1%),especially Escherichia coli(17.2%),Pseudomonas aeruginosa(16.7%) and Klebsiella pneumoniae(12.7%),and they all beared high antibiotics resistance. CONCLUSIONS Special attention should be paid to abdominal surgical wound infection.

Objective To evaluate the occurrence of multidrug-resistant organism (MDRO)infection in a general hospital,and take effective comprehensive intervention measures,so as to reduce MDRO infection.Methods Targeted monitoring on MDROs was performed from October 2012 to December 2013,comprehensive intervention measures were conducted,the occurrence of MDRO infection before and after intervention was compared.Results A total of 62 384 pa-tients were investigated,17.91%(n=11 176)were sent specimens for pathogen culture,606 times of culture for patients’ specimens were detected MDROs,292(0.47%)cases were MDRO healthcare-associated infection(HAI),314 were com-munity-acquired infection or colonization.MDRO infection case rate decreased from 0.65%(75/11 603)before intervention to 0.26%(36/13 875)after intervention (χ2 =21.08,P <0.05).Conclusion Comprehensive intervention measures can effectively reduce the occurrence of MDRO HAI.

Objective By studying the change of the special antibodies titer IgG, IgM and nucleocaspid to SARS corona virus in family clustering cases , searching and testing the special antibody to SARS corona virus in the patients kinfolks Method Testing special antibody titer to SARS corona virus of 14 patients from 5 different families and their 10 kinfolks continuously by IFA and antigen capturing ELISA methods, taken samples in the 7 th , 14 th , 30 th , 60 th , 120 th , 180 th , 210 th ,270 th ,360 th day after SARS patients infected by SARS corona virus, dilute them, and then measure titers of three kinds of antibodies ResultsDuring the testing of IgG antibody titer of the 14 SARS patients by IFA method, in the 120 th day, the average titer is up the highest value, it is 1/1 120; in the 180 th day, the average titer begins to descend, it is 1/262 in the 360 th day, the average titer is 1/71 During the testing of IgM titer, the average titer is 1/32, it is obviously lower than it in IgG testing; the IgM titer of the most SARS patients are disappear after 120 days The average value of nucleocaspid antibody titer is lower than it in IgG antibody But there are some differences in 5 cases While IgG antibody titer begins to descend in the 180th day, nucleocaspid antibody titer begins to ascend obviously, it is up to 1/790 210 th day begins to descend In the meantime, we have tested special antibody to SARS corona virus of their 10 kinfolks (include 2 children) who have contacted with SARS patients closely The samples are taken in the 14 th , 30 th , 60 th day, and all the special IgG, IgM and nucleocaspid antibody to SARS corona virus are negative ConclusionBy testing the special IgG antibody to SARS corona virus of the 14 family clustering cases ,we find the special IgG antibody titer of the SARS patient is higher, and it can remain for a long time As for the nucleocaspid antibody titer of some SARS patients ascend obviously after 180days, we think that it provide useful information for vaccine development and it is necessary for us to study more in the clinic There is no special blood serum antibody to SARS corona virus in their 10 kinfolks of the SARS patients

BACKGROUND: Acupuncture therapy plays a very important role in the treatment of lateral epicondylitis. However, due to the diverse characteristics of acupuncture therapy, the current research mostly focuses on a simple comparison between acupuncture therapy and conventional blocking therapy. OBJECTIVE: To compare the efficacy and visual analogue scale score of different acupuncture therapies for lateral epicondylitis using a Bayesian network meta-analysis. METHODS: Randomized controlled trials on acupuncture therapy for lateral epicondylitis included in PubMed, The Cochrane Library, CNKI, VIP, and WanFang were searched. The search time was from inception until October 2019 in each database. Two researchers independently screened and extracted data according to the inclusion criteria, and then evaluated the quality of the literature. Direct meta-analysis and network meta-analysis of data were performed using ADDIS 1.16.8 software. RESULTS AND CONCLUSION: A total of 2 318 lateral epicondylitis patients were included in 32 randomized controlled trials/controlled clinical trials, concerning 6 treatment measures, including warming needle, fire needle, electroacupuncture, filiform needle acupuncture, Fu’s acupuncture, fire needle plus filiform needle. Network meta-analysis results show that: in terms of efficiency, warming needles are better than electroacupuncture, warming needles are better than filiform needles, fire needles are better than warming needles, fire needles are better than electroacupuncture, fire needles are better than filiform needles, Fu’s acupuncture is better than electroacupuncture, Fu’s acupuncture is better than filiform needles, and fire needle plus filiform needle is better than filiform needles alone. In terms of the visual analogue scale score, warming needles are better than electroacupuncture, warming needles are better than filiform needles, fire needles are better than electroacupunture, fire needles are better than filiform needles, Fu’s acupuncture is better than electroacupuncture, Fu's acupuncture is better than filiform needles, fire needle plus filiform needle is better than electroacupuncture. Efficiencies rank from the best to the worst: Fu’s electroacupuncture>fire needle>fire needle plus filiform needle>warming needle>electroacupuncture needle>filiform needles. The visual analogue scale scores rank as follows: Fu’s acupuncture>fire needle+filiform needle>fire needle>warming needle>filiform needle>electroacupuncture. The direct meta-analysis results are highly consistent with the network meta-analysis results, indicating that there is consistency between the direct and indirect comparison, that is, transitive. In the clinical treatment of lateral epicondylitis, Fu’s acupuncture can be preferentially selected, but each acupuncture therapy has advantages and disadvantages. In clinical practice, the appropriate treatment should be selected in accordance with the actual situation and dialectical Chinese medicine.

Objective To investigate the prevalence of psoriatic arthritis (PsA) in patients with psoriasis and its clinical features.Methods A cross-sectional study was conducted among patients diagnosed with psoriasis from January 2014 to January 2015.Through a questionnaire survey,the diagnosis of PsA was confirmed according to the Classification Criteria for Psoriatic Arthritis (CASPAR) in patients with suspected PsA.Clinical data were collected from patients with newly and previously diagnosed PsA.Statistical analysis was carried out by t test for two-group comparisons,one-way analysis of variance (ANOVA) for multi-group comparisons,and chi-square test for comparisons of rates.All the statistical tests were two-sided.Results Totally,1 062 outpatients with psoriasis were enrolled into this study,and 125 were suspected to have PsA.According to the CASPAR,70 (6.59％) patients were finally diagnosed with PsA,with the ratio of male to female being 2.1 ∶ 1,and 45 of them (64.29％) were newly diagnosed.Psoriasis vulgaris lesions were observed in 50 (71.43％) patients with PsA,and were the most common type of skin lesions in patients with PsA.There were 5 clinical types of PsA in these patients,including asymmetrical oligoarthritis (23 cases,32.86％),symmetric polyarthritis (19 cases,27.14％),distal interphalangeal predominant arthritis (10 cases,14.29％),vertebral or sacroiliac arthropathy (7 cases,10.00％),and arthritis mutilans (11 cases,15.71％),with some overlap among these clinical types.As relatively distinctive manifestations of PsA,dactylitis and enthesitis were observed in 14 (20.00％) and 8 cases (11.43％) respectively.In addition,43 (61.43％) cases had nail involvements.Conclusion To master clinical features of PsA and to diagnose it early are of great significance for long-term prognosis of PsA patients.

OBJECTIVE To evaluate the diagnosis value of the procalcitonin(PCT) test in the lower respiratory tract infection(LRTI),and to provide the application of PCT in the bacterial infectious disease.METHODS Procalcitonin concentrations were measured using the quantitative immunofluorescence test in 93 patients and the results were compared with the levels of C-reactive protein(CRP) and white blood cell count(WBC).Samples were collected and divided into 2 groups,one including 63 cases(bacterial infected group) the other including 30 cases(non-bacterial infected group) corresponding to their clinical diagnosis(temperature,heart rate,bacteremia culture,CRP,WBC count).RESULTS The levels of PCT in bacterial infected group were significantly higher than in non-bacterial infected group(P

Objective To discuss peer education on the rehabilitation in schizophrenia recovery.Methods According to the order of admission,108 cases of hospitalized recovery of schizophrenia patients were divided into observation group and control group,each group in 54cases.The observation group received psychiatric conventional treatment and care at the same time add peer educations,the control group only accepted psychiatric conventional treatment and care.The observation group was given for a period of 20 weeks peer education.The nurse brief mental scale (N -BPRS),self -knowledge and treatment attitude questionnaire scale (ITAQ)were assessed in the two groups at the beginning,10 weeks,20 weeks.Results The difference of N -BPRS score between the two groups was not statistically significant (t =0.191,P =0.850).In the observation group,the scores had significant differences between 10 weeks and 20 weeks peer education (t =2.757,P =0.069;t =4.000,P =0.000).The ITAQ scores of the observation group at the beginning,20 weeks peer education were (11.22 ±3.55)points,(17.22 ±4.31)points, the difference was statistically significant (P <0.01).In control group,ITAQ scores before and after treatment were (10.84 ±5.19)points,(13.12 ±6.12)points,the difference was not statistically significant (P >0.05).Conclusion Schizophrenia convalescence patients accept peer education is helpful to rehabilitation.
