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.

411 subjects were divided into six groups according to their FPG levels.And OGTT was carried out.Result showed that along with the FPG increasing, HOMA ?-cell index and ?I30 /?G30 were decreased progressively, and the fasting serum proinsulin level and ratio of proinsulin /insulin were increased markedly.The area under insulin curve decreased gradually when FPG was above 8 mmol/L. In conclusion, FPG is a reflection of islet ? cell function.

The microenvironment after peripheral nerve injury becomes complicated for axon regeneration, which can be promotion, inhibition, or both. This paper summarized the researches about the effect of microenvironment on axon regeneration after peripheal nerve injury.

Objective To investigate the resistance-related genes of Shigella sonnei with decreased susceptibility to fluoroquinolones.MethodsA total of 131 strains of Shigella sonnei were analyzed for their antimicrobial susceptibility.Mutations within the quinolone resistance determining regions (QRDR) of gyrA and parC were detected by polymerase chain reaction (PCR) and PCR products were then sequenced. Meanwhile, the plasmid-mediated quinolone resistance (PMQR) genes,qnr and aac(6')-Ib-cr were screened by PCR.ResultsResistance rates of 131 Shigella sonnei isolates to nalidixic acid,tetracycline,ampicillin and trimethoprim-sulfamethoxazole were 100.0％,93.9％,93.2％ and 92.8％,respectively.All strains were susceptible to norfloxacin,ciprofloxacin,levofloxacin,while 94％ nalidixic acid-resistant Shigella sonnei strains showed reduced susceptibilities to fluoroquinolones.All of nalidixic acid-resistant Shigella sonnei strains presented a single mutation at codon 83 (Ser→Leu) of gyrA genes,but no mutations were detected in parC gene.And PMQR genes qnr and aac (6’)-Ib-cr were not detected.Conclusions The nalidixic acid-resistant Shigella sonnei strains with reduced susceptibility to fluoroquinolones are common in the clinical practice,which may mainly due to a single mutation at codon 83 (Ser→Leu) of gyrA genes.

ABSTRACT:Objective To validate that relaxin can resist hepatic fibrosis at the cellular level and explore its molecular mechanism in order to provide experimental basis for the treatment of liver cirrhosis.Methods Cultured HSC-T6s were treated with different concentrations (20,50 and 100 ng/mL)of recombinant human relaxin-2 (RLX-2).The proliferation of HSC-T6 was measured by MTT colorimetric assay.The content of type Ⅰcollagen in the cell culture supernatant of each group was detected by ELISA at 48 h of drug intervention;RT-PCR was used to detect the mRNA expressions of CTGF and TGF-β1 in HSC-T6 at 48 h of drug intervention.Results RLX-2 inhibited the proliferation of HSC and reduced type Ⅰ collagen content of HSC cells.It also inhibited the CTGF mRNA expression of HSC,but did not have a significant effect on the expression of TGF-β1 mRNA. Conclusion In the experiment of culturing HSC-T6 in vitro,RLX-2 may play a role in rat liver fibrosis by inhibiting cell proliferation and type Ⅰ collagen and CTGF mRNA expressions.

Objective To study the effects of Batroxobin( BX) on the intimal proliferation of graft veins. Methods In this study 25 dogs were selected and evenly divided into experimental group, control group and sham operation group. In experiment and control group, a segment of auto- femoral vein were grafted into femoral artery by clean microsurgery technique. In experimental group, BX was given at the dosage of 0. 1 BU/kg, dayly?2 preoperatively, and once a day for consecutive 6 days postoperatively. Plasma NO, ET was determined in the three groups. Computer image analysis system was applied to calculate the thickness of neointima and media in the vein grafts, immunohistochemistry was used to identify PCNA and C-myc. Result The experimental group had a higher level of NO and lower level of ET compared with control group and sham operation group(P 0. 05 ). The PCNA expression in experimental group was statistically different from that of the control group(P

OBJECTIVE: To optimize the extraction process of Fructus Schisandrae Chinensis. METHODS: Taking the contents of schizandrin, schisantherin A, deoxyschizandrin, r-schizandrin as the indexes, the influence on the extraction process by extract solvent and medicinal material particle diameter was examined, and the extraction parameters were optimized. RESULTS: Active components of Fructus Schisandrae Chinensis, after the medicinal material being crushed, can be effectively utilized through extracting by alcohol. The optimized extraction parameters were as follows: the medical material being ground into 40 meshes, extracted twice by 70% alcohol, 2 hours per time. CONCLUSION: The optimized extracting process works better than current technique adopted for formulated granule preparation, and can ensure quality to the highest degree.

OBJECTIVE: To optimize the process for extraction and purification of Schisandrin in Fructus Schisandra Chinensis. METHODS: The orthogonal test L9( 34) was adopted to optimize the water extraction process using Schisandrin and its extracts as indicators. The parallel test was used to optimize the parameters of the alcohol precipitation technique. RESULTS: The optimized process for extraction and purification of Schisandrin was as follows: extracting three times using 10- fold water, 1. 5h each time, with filter liquids concentrated to 1. 4g of crude drug mL- 1 then precipitated to 80% ; filtering alcohol liquids, and adjusting pH value to 7. CONCLUSIONS: This method can be used as a reference for the extraction of Fructus Schisandra Chinensis.

Objective To compare the clinical outcomes of total laparoscopic pancreatoduodenectomy (TLPD) and open pancreaticoduodenectomy (OPD).Methods From August 2013 to December 2014,137 pancreaticoduodenectomies (PDs) were performed at the Department of General Surgery of our hospital,of which 19 TLPDs were performed at the Department of Minimally Invasive Surgery (the Experimental group).At the same time,another cohort of 19 OPDs were matched for age,gender,body mass index (BMI),ASA score and tumor site and they formed the control group.The clinical data in the perioperative period were evaluated,and the short-term clinical outcomes were compared.Results Operation time in the experimental group was significantly longer than the control group [(407.8 ± 146.5)min vs (263.3 ± 65.3) rmin,P ＜ 0.05].The mean intraoperative blood loss [(309.7 ± 151.2)ml vs (509.4 ± 309.9)ml],mean intensive care time after surgery [(47.5 ±16.8)h vs (68.1 ± 19.1)h],mean postoperative time to pass flatus [(3.5 ± 1.1) d vs (4.3 ± 1.1) d],mean postoperative hospitalization stay [(8.8 ± 2.1) d vs (10.8 ± 2.3)d] and mean incision length [(5.1 ± 0.9)cm vs (14.4 ± 1.3)cm] in the experimental group were significantly different from the control group (P ＜ 0.05).There were no significant differences on the intraoperative R0 resection rates,intraoperative pathology,tumor size [(20.6 ± 9.6) mm vs (25.9 ± 10.2)mm],number of lymph node dissected [(17.7 ± 6.5) vs (19.4 ± 5.6)],complication rates,recurrence rates and mortality between the two groups (P ＞ 0.05).Conclusions TLPD had comparable safety and therapeutic outcome when compared with OPD.Moreover,TLPD has the advantages of less bleeding,smaller wounds and faster postoperative recovery.TLPD requires specialized appliances and equipments,better surgeon experience and patient selection to achieve a high success rate.
