Objective To explore the preoperative misdiagnosis in the breast cancer and the methods to improve the diagnostic accordance rate. Methods The preoperative diagnosis and results of 358 cases with breast cancer has been analysized retrospectively in the recent ten years. Results Total Cases with present diagnostic technique diagnosed befor operation was 176 only;the accordance rate was less than 50%.With aspiration biopsy and molybdenum palladium roentgenograph,the rate was 25%(79 cases).The actual preoperative accordance rate was less than 10%(32 cases).It is said approximately 90% cases were postoperatively diagnosed. Conclusion The present excision biopsy not only has made many patients lost the chance of chemotherapy preoperation, but also interferenced the application of new therapic methods in the clinical practice.Infrared spectroscopy and ultrasonography have been commonly used in the clinical practice.With the low diagnostic accordance rate,they were applied only for screening.With simplity and high diagnostic accor dance rate,aspiration biopsy and molybdenum pall adium roentgenograph should be enrolled extensively in the clinical practice. The puncture and specimen fixing technique also should be improved.

Objective To find an effective operational approach that can mostly reduce heat and other injury to Calot's triangle when separating and anatomizing it at LC operation.Method We abandoned traditional hot separating method by electric coagulation hook which can cause hot injury easily and cold separating method simply by elastic separating plier which can cause errhysis and illegibility of operational field.We applied sucting and scraping cold separating method mainly by suction apparatus which can keep operational field clear and avoid hot injury.Result 52 cases with different cholecyst disease (including cholecystolithiasis,cholecyst polyp,acute cholecystitis with edema and acute cholecystitis with partly gangrene) were adopted by this method and achieved satisfacted effect.Conclusion Sucting and scraping cold separating method are easily operated and can mostly keep separated tube skeletonized.It can avoid hot and other injury in operation,keep operational field clear by less errhysis.To acute cholecystitis with edema it has more advantage and are worth to adopting.

Objective To investigate and compare the clinical efficacy of mifepristone alone and combined with Gongliuxiao capsule in the treatment of uterine fibroids.Methods 106 patients with uterine fibroids in Harrison International Peace Hospital from December 2012 to December 2013 were selected.The patients were randomly divided into control group and experimental group(n=53).The former were treated with mifepristone alone while the later were treated with the combination of mifepristone and Gongliuxiao capsule.All the patients were given 2 courses of treatment with 12 weeks for a course.The menstrual phase,volume of menstruation,uterus and the volorne of uterine fibroids before and after the treatment,and the clinical efficacy of both groups were evaluated.All the results were recorded and compared. Results The menstrual phase,volume of menstruation,uterus and uterine fibroids of both groups after the treatment were significantly less than those before treatment (P <0.05 ).And the total effective rate of experimental group was 92.45%,which was significantly higher than 73.58% of control group.Both groups had some mild adverse reactions,which didn’t affect the treatment.Conclusion The combination of mifepristone and Gongliuxiao capsule has a great efficacy in the treatment of uterine fibroids.Compared with the use of mifepristone alone,the combination treatment is much more effective.

Objective To investigate the common pathogenic bacteria distribution and drug resistance in children with lower respiratory tract infection,which guide how to use antibiotics and decrease the progress of drug resistance.Methods Nine hundred and ninety-seven cases of lower respiartory tract infection were analyzed retrospectively in the Department of Pediatrics of the First Hospital of Lanzhou University from Jan.2008to Dec.2010.The sputum samples were collected for routine bacterial cultivation.The antibiotic sentivity test were used for pathgen.Results The phelm cultivition amount is 997,bred and separated 498 bacteria of 425samples,the check rate is 42.73％.There were 151 Gram Positive Bacteria,which had a rate of 30.32％,and 321 Gram Negative Bacteria,which had a rate of 64.46％,and 26 fungi whose rate is 5.62％.The main bacteria was changed during the three years.There were significant differences in detection rate of pseudomonas aeruginosa(PA) and haemophilus parainfluenzae(HPI) during the three years.PA was declining while HPI was rising.There were no significant differences in detection rate of streptococcus pneumoniae( SP),staphylococcus aureus ( SA),escherichia coli( E.coli ),klebsiella pneumoniae ( K.pn ),haemophilus influenzae ( HI ) and fungi.There were no significant differences in detection rate of PA between different age groups.With the increasing of age,the detection rate of SP,HI and HPI trended to rise,whereas the detection rate of SA,E.coli and K.pn trended todecline.The resistance phenotype of SA,E.coli and HPI in detection rate had significant difference in each year.SP and SA were most sensitive to linezolid and vancomycin.Ecoli and K.pn were most sensitive to carbapenems.HI and HPI were relatively sensitive to common antibiotics.Conclution In the past three years,the main pathogen in children with lower respiartory tract infection were Gram Negative Bacteria.Among the bacteria,SP and Ecoli was the most,followed by SA,HI,K.pn,and HPI.These bacteria had signifeicant difference in dectection rate between different age groups.SP and SA were most sensitive to vancomnycin and linezolid.E.coli and K.pn were most sensitive to carbapenems.HI and HPI were relatively sensitive to common antibiotics.So clinical doctors should use antibiotics based on the microorganism cultivation and sensitivity test m order to decrease the drugresistance strain.

The carotid plaque (CP) detachment can induce thrombosis, which may lead to cerebral vascular disease. In recent years,research of CP is mainly focused on qualitative and quantitative analysis of vulnerable plaque. Therefore, it is important to choose therapeutic method and opportunity according to the structure and stability of the plaque. This article reviews the progress in the diagnosis of plaque from the aspects of common ultrasound, contrast enhanced ultrasound, ultrasound real-time tissue elastography, intravascular unltrasound, digital subtraction angiography (DSA), comuted tomography angiography (CTA), magnetic resonance imaging (MRI) and optical coherence tomography (OCT). Common and all kinds of new ultrasonic technology can be used to evaluate the vulnerability of CP from different aspects.

AIM: To investigate the infection factors,diagnosis and treatment of endophthalmitis after intraocular foreign body injury.METHODS: Totally 256 cases with intraocular foreign bodies including the occurrence of endophthalmitis in 42 cases were analyzed retrospectively.RESULTS: The incidence of endophthalmitis after intraocular foreign body injury was 16.4%.Posterior segment foreign bodies and combined with traumatic cataract were the risk factors of endophthalmitis after intraocular foreign body injury (all P<0.05).Intravitreal injection of vancomycin hydrochloride and ceftazidime in the treatment of intraocular foreign body injury reduced the incidence of endophthalmitis (P<0.05).Types and sizes of intraocular foreign bodies,the time of extraction and the condition of wound had no significant effect on the incidence of endophthalmitis (all P>0.05).Vitrectomy was the main treatment of endophthalmitis.CONCLUSION: Posterior segment foreign bodies and combined with traumatic cataract were the risk factors of endophthalmitis after intraocular foreign body injury.It should be kept the integrity of the posterior capsule of lens in traumatic cataract surgery.Intravitreal injection of vancomycin and ceftazidime is recommended in emergency surgery.Vitrectomy should be performed as soon as possible when confirmed endophthalmitis.

This study was aimed to analyze the similarities of characteristics between members of“metal family” in the five elements. Wittgenstein’s family resemblance theory was used in the analysis of members assigned to the category of“metal family”, which included metal, autumn, west, white, pungent and lung. The results showed that there was family resemblance between members of“metal family”. It was concluded that members were classified into the category of“metal family” through analogical reasoning of family resemblance. Any member to be classified as a member of“metal family” showed similarity with at least one of other family members. Certain member in the“metal family” had similarities in different aspects with multiple members in the family. Any two members of“metal family” may not always have any similarities. It can be deduced that certain physiological functions of lung were not owned by the lung itself, but by the characteristics of“metal family”. The range of“metal family” can be expanded and multiplied. The“metal family” can build new members in different areas.

Objective To observe the clinical therapeutic effect of Capsule Long-Bi-Xiao(LBX) in treating benign prostatic hyperplasia(BPH).Methods 64 patients of deficiency of Qi and blood stasis type suffered with BPH were randomly divided into two groups.30 patients in the control group were treated with Capsule Long-Bi-Shu,while other 34 patients in the treated group were treated with LBX.Each group was observed for there months respectively.Results LBX decreased the international index of prostatic symptom(I-Pss) and the bother score(BS),improved the prostatic symptoms,raised the peak flow rate(Qmax) and the average flow rate(Qave),shrinked a portion of patients′ volume of prostate gland,reduced the volume of residual urine.After treatment,in the treated group,I-PSS and BS were reduced distinctly,and Qmax and Qave were heightened obviously,which was more effective than those in the control group.Conclusion LBX can achieve good action in the therapy of BPH by improving clinical symptoms,diminishing the volume of prostate and ameliorating the difficulty of urination.

Objective To evaluate the effects of combined induction therapy of interferon(IFN) and chemotherapy on survival of the patients with small cell lung cancer(SCLC)by meta-analysis.Methods Search all of clinical trials for addition of IFN to initial chemotherapy and single chemotherapy for induction therapy in SCLC patients in MEDLINE、EMBASE and COCHRANE Library.The references of related studies and education books of ASCO and ESMO meeting were handsearched.The quality of included trials was evaluated.Data were extracted by two reviewers independently with a designed extraction form.Revman 4.2.7 software was used for data analysis.Results The addition of IFN increased 1-year survival and response rate,but both of the results had no significant statistical difference.Conclusion IFN-chemotherapy induction treatment might not influence survival and response rate of patients with NSCLC.To resolve the problem,a series of controlled,prospective,randomized,double-blind,well-designed,multi-center trials should be performed.
