Objective To evaluate the effect of preserving the intercostobrachial nerve(ICBN) during modified radical mastectomy for breast cancer.Methods Preservation of ICBN during modified radical mastectomy was performed in 100 patients with stage Ⅰ or stage Ⅱ breast carcinoma.All patients were followed up after operation.Results Ninty-one patients had normal sensation of the skin of upper arm on operated side,while medial side paresthesia of the upper arm occurred in 9 cases within the postoperative follow up period.Conclusions Preserving the intercostobrachial nerve in modified radical mastectomy for patients with breast cancer can decrease the incidence of abnormal sensation of the skin of affected upper arm,and improve the quality of life of patients after operation.

OBJECTIVE: To investigate the utilization and its trend of antidepressants in Beijing.METHODS: The antidepressants used in 70 hospitals in Beijing from 2004 to 2006 were analyzed statistically in respect of the variety,consumption sum,DDDs and DDC etc.RESULTS: The consumption sum of the antidepressants used in Beijing increased year by year.CONCLUSION: Selective serotonin reuptake inhibitors(SSRIs) have become the first-line antidepressants,but the application of the tricyclic and tetracyclic antidepressants decreased year by year.The new antidepressants such as venlafaxine increased sharply.

Objective To compare the clinical effect about hysteroscope and laparotomy in patients with submucous uterine myoma. Methods Eighty-four patients with submucous uterine myoma were randomly divided into control group(n=42)and observation group(n=42). The patients in the control group were given laparotomy treatment,while in the observation group were given hysteroscope treatment. The intraoperative and postoperative conditions between the two groups were recorded and compared. Results The operation time, intraoperatve blood volume,postoperative anal exhaust time,postoperative pain intensity( judged by VAS)and hospital stays periods in observation group were(52. 5 ± 9. 6)min,(84. 6 ± 16. 7)ml,(21. 5 ± 3. 6)h,(3. 6 ± 1. 4)scores and(5. 4 ± 1. 8)d,significant lower than those in control group((72. 6 ± 13. 4)min,(116. 8 ± 28. 4)ml,(29. 8 ± 5. 4)h,(1. 8 ± 0. 5)scores,(9. 6 ± 2. 4)d),and the differences were significant( t=5. 468,4. 263,4. 438,6. 283;P =0. 006,0. 018,0. 024,0. 001,0. 002 ). While the hospitalization costs in observation group was(7394. 9 ± 1164. 8)yuan,higher than that of the control group((5 428. 9 ± 824. 5) yuan;t=4. 647,P=0. 036). There were no statistical significant in terms of recurrence rate between the two groups( 20. 5% vs. 19. 6%;χ2 = 0. 236,P = 0. 637 ). Conclusion Treatment of hysteroscope surgery on submucosal myoma of uterus has the advantages of small trauma and quick recovery and it is an ideal surgical method for uterine myoma.

ObjectiveTo evaluate the therapeutic effect ofHuangqi-Guizhi-Wuwu decoction in patients with diabetic peripheral neuropathy (DPN).MethodsA total of 78 patients with DNP were included and divided into a control group and a treatment group, with 39 in each group. The patients in the control group were administrated with appropriate exercise, control diet, hypoglycemics, mecobalamin and vitamin B1, those in the treatment group were receivedHuangqi-Guizhi-Wuwu decoction on the basis of the control group. The patients in both groups were treated for 8 weeks. The serum activities of superoxide dismutase (SOD), glutathione peroxidase (GPx) and catalase were determined by enzymatic-colorimetric method, and the serum malondialdehyde level was measured using colorimetric method. Sensory nerve conduction velocity (SCV) and motor nerve conduction velocity (MCV) were measured using an Electromyograph and Evoked Potential Equipment.ResultsAfter treatment, MCV (43.12 ± 4.1 m/svs. 40.27 ± 2.8 m/s;t=3.585,P<0.05)、SCV (41.51 ± 3.4 m/svs. 39.63 ± 3.5 m/s;t=2.406,P<0.05) in the treatment group were significantly increased than those in the control group. The serum activities of SOD (51.1 ± 6.6 U/mlvs. 47.6 ± 3.9 U/ml;t=2.851,P<0.01),GSH-Px (241.7 ± 36.1 U/mlvs. 213.9 ± 31.7 U/ml;t=3.614,P<0.01) in the treatment group were significantly increased than those in the control group. The total efficiency in the treatment group was significantly higher than that in the control group (87.2%vs. 69.2%;χ2=4.333,P=0.033).ConclusionsHuangqi-Guizhi-Wuwu decoction combined with conventional therapy could improve antioxidant capacity and control DPN progress in patients with DPN.

Objective To observe the curative resection of oxycodone hydrochloride controlled intravenous analgesia pump after treatment of cervical cancer (patient-controlled-intravenous analgesia, PCIA) and the adverse effect of pain.Methods March 2016 to February 2017 undergoing open radical resection of cervical cancer patients with 108 cases, were randomly divided into observation group(n=54) and control group(n=54), the observation group was given oxycodone hydrochloride injection intravenous patient-controlled analgesia pump, the control group were treated with Sufentanil Citrate Injection patient-controlled analgesia pump, anal exhaust time, contrast two groups of patients with adverse drug reactions and postoperative 6h, 12h, 24h, 48h (NRS Numeric Rating Scale, NRS) pain score.ResultsPain score: 12h observation group compared with the control group NRS pain score (P<0.05), with statistical difference, 6h, 24h, 48h time group NRS pain scores haveno statistical difference.Adverse reactions: in the observation group, 7 cases of nausea, vomiting in 6 cases, 2 cases of hypotension;control group 16 cases of nausea and vomiting in 14 cases, 1 cases of hypotension, 1 cases of skin allergy, 1 cases of dizziness, adverse reaction rates were significantly higher than the observation group (P<0.05), the difference was statistically significant.Exhaust time: observation group (2.93±0.63) days, the control group (2.76±0.61) days, no statistical significance.ConclusionOxycodone controlled intravenous analgesia pump for analgesia in patients with radical resection of cervical carcinoma after open surgery, with less adverse reactions.

ObjectiveTo explore the roles of Toll-like receptor (TLR) 3,7 and 9 in the pathogenesis of pityriasis rosea.MethodsThis study recruited 40 patients with pityriasis rosea and 40 normal human controls.Reverse transcription-PCR was carried out to detect the expressions of TLR3,7 and 9 in peripheral blood lymphocytes of these subjects.ResultsThe mRNA expressions of TLR3,7 and 9 in peripheral blood lymphocytes were significantly higher in patients with pityriasis rosea than in the normal human controls (Z =4.239,3.745,2.658,all P ＜ 0.05).There was a positive correlation between the expression of TLR3 and TLR7(r =0.574,P ＜ 0.01 ) as well as between that of TLR3 and TLR9 (r =0.551,P ＜ 0.01 ) in the patients,while there was no correlation between TLR7 and TLR9 expression in the patients or between the expressions of TLR3,TLR7 and TLR9 in the controls.ConclusionVirus infection might be involved in the pathogenesis of pityriasis rosea via TLR pathways.
