Objective To investigate the clinical diagnostic significance of detecting T in peripheral blood lymphocyte subsets (CD4+,CD8+ and the ratio of pulmonary tuberculosis with diabetes) and explore drug therapy of the five thymus peptide combined anti-tuberculosis on the diabetes complicated with pulmonary tuberculosis.Methods Eighty cases of pulmonary tuberculosis complicated with diabetes mellitus were selected as our treatment subject,who were treated with anti-tuberculosis drug treatment and five thymus peptide regulating immunity treatment.T lymphocyte subsets (CD4 +,CD8 + and their ratio) were detected.Meanwhile acid-fast bacilli and image detection were performed.Another 80 cases were as our control group that treated with anti-tuberculosis drug.Results Following the thymus peptide five treatment for 1,2,and 6 months,T lymphocyte subsets were (CD4+:(34.34 ± 7.32) ％,(39.23 ± 6.62) ％,(41.06 ± 7.13) ％),(CD8+:(31.42 ±8.91)％,(32.52 ±8.58)％,(32.12 ±8.59)％),(CD4+/CD8+:(1.23 ±0.31),(1.34 ±0.30),(1.36 ± 0.32),higher than that of before treatment (30.26 ± 8.25) ％,(30.36 ± 9.86) ％,(1.13 ± 0.42) CD4 +.Through 2 months treatment,CD4+,CD4+/CD8+ of patient in treatment groups were different with that of control group (P ＜ 0.01 or P ＜ 0.05).80 patients after anti-TB plus application thymopentin regulating immunity for 2 months,normal sputum negative conversion rate of CD4+ was 97.2％ and improvement rate was 98.0％.However cases with high CD4+ T lymphocyte subsets showed 78.6％ negative rate of acid-fast bacilli and 88.0 ％ cured rate,and there was significant difference (x2 =4.764,7.680,respectively,P ＜ 0.05).Conclusion Thymic peptide five might have the ability of improving the cellular immune function in patients with pulmonary tuberculosis and diabetes.The prognosis is better when T lymphocyte subsets CD4+ of patient was back to normal through treatment.

Objective To investigate the effect of local application of triamcinolone acetonide in promoting wound healing and recurrence after granulomatous lobular mastitis (GLM) operation. Methods The clinical data of 55 GLM patients with the diameter > 5 cm were retrospectively analyzed, and all patients treated with incision drainage to breast abscess and removal of inflammatory lesions. Thirty - one patients were treated with routine dressing change after operation (control group), and 24 patients were treated with routine dressing change and triamcinolone acetonide injection after operation (experiment group). The wound dressing time, recovery rate and recurrence rate were compared between 2 groups, and hormone related adverse reaction of experiment group was observed. Results The wound dressing time in experiment group was significantly shorter than that in control group:(58 ± 19) d vs. (71 ±25) d, and there was statistical difference (P<0.05). There were no statistical differences in the recovery rate and recurrence rate between experiment group and control group:91.7%(22/24) vs. 83.9%(26/31) and 9.1%(2/22) vs. 15.4% (4/26), P>0.05. The patients of experiment group did not have the hormone related adverse reaction. Conclusions The local application of triamcinolone acetonide after GLM operation can accelerate the wound healing, and it may also contribute to higher recovery rate and lower recurrence rate.

Objective:To investigate how urothelial carcinoma-associated 1 (UCA1) and miR-18a modulates acquired tamoxifen resistance and the relevant mechanisms in estrogen receptor (ER) positive cancer cells.Methods: qRT-PCR was performed to detect UCA1 and miR-18a expression in breast cancer cells.Dual luciferase assay was performed to detect the binding between miR-18a and UCA1 3′UTR.Tamoxifen sensitive MCF-7 cells were transfected with UCA1 expression vector or miR-18a inhi-bitors.Tamoxifen resistant LCC9 and BT474 cells were transfected with UCA1 siRNA or miR-18a mi-mics.CCK-8 assay was performed to detect cell viability.Soft agar assay was performed to assess cell colony formation.Flow cytometric analysis was performed to check cell cycle distribution.Results: UCA1 was significantly upregulated in tamoxifen resistant LCC2,LCC9,and BT474 cells than in tamoxifen sensitive MCF-7 cells.UCA1 expression was significantly upregulated in MCF-7 cells after treatment with 0.1 μmol/L tamoxifen.UCA1 overexpression enhanced cell viability of MCF-7 cells after tamoxifen treatment,while UCA1 siRNA significantly suppressed viability of LCC9 and BT474 cells after tamoxifen treatment.In MCF-7 cells,compared with vector control+tamoxifen group,the average cell colony number and colony size of the UCA1+tamoxifen group was 19.0％ more and 29.0％ larger respectively,while the proportions of the cells in G1 phase and in S phase were 7.3％ lower and 6.7％ higher respectively.In BT474 cells,compared with siRNA control+tamoxifen group,the average cell colony number and colony size of the si-UCA1+tamoxifen group were 54.0％ less and 42.0％ smaller respectively,while the proportions of the cells in G1 phase and in S phase were 9.0％ higher and 6.2％ lower respectively.UCA1 directly interacted with miR-18a and reduced its expression in ER positive breast cancer cells.Knockdown of miR-18a increased viability of MCF-7 cells after tamoxifen treatment,while miR-18a overexpression significantly reduced viability of BT474 cells after tamoxifen treatment.In MCF-7 cells,compared with miRNA inhibitor control+tamoxifen group,the average cell colony number and colony size of the miR-18a inhibitor+tamoxifen group were 15.0％ more and 33.0％ larger respectively,while the proportions of the cells in G1 phase and in S phase were 8.8％ lower and 5.3％ higher respectively.In BT474 cells,compared with miRNA control+tamoxifen group,the average cell colony number and colony size of the miR-18a mimics+tamoxifen group were 47.0％ less and 25.0％ smaller respectively,while the proportions of the cells in G1 phase and in S phase were 13.3％ higher and 7.9％ lower respectively.Conclusion: UCA1 can increase tamoxifen resistance of ER positive breast cancer cells via competitively inhibiting of miR-18a.

OBJECTIVE To investigate the reasons and preventive measures of recurrent laryngeal nerve injury during operation in patients with benign thyroid neoplasm. METHODS The clinical data of 2243 cases with benign thyroid neoplasm were reviewed. The relations among different neoplasm regions, different procedures and injury of recurrent laryngeal nerve were analyzed. RESULTS Injury incidence of recurrent laryngeal nerve in this study was 3.0 %. In cases with nodular goiter on the dorsum of thyroid and recurrent laryngeal nerve exposed during operation, injury incidence of recurrent laryngeal nerve was 1.0 %. And there was no recurrent laryngeal nerve injury in cases with nodular goiter on other region of the thyroid. In cases used locality protection during operation, injury incidence of recurrent laryngeal nerve was 7.6 % when benign lesions on the dorsum of thyroid and was 0.17 % when benign lesions on other region of the thyroid. CONCLUSION In cases with nodular goiter or adenoma on the dorsum of thyroid, exposing recurrent laryngeal nerve is necessary during operation and in cases with benign lesions on other region of thyroid, locality protection is useful. There are three major routes for recurrent laryngeal nerve exposure.

Objective To investigate the influence of indomethacin to the unite treatment effect on chronic phase myeloid leukemia (CML-CP) with interferon alpha-2b (IFNα-2b) and low dose cytarabine (LD-Ara-C).Methods 22 CML-CP patients were randomly divided into two groups.Control groups (10 cases) injected with IFNα-2b (3 million units),injection frequency was q.o.d,the duration of treatment was about 3-18 months,cytarabine (Ara-C) by slowly intravenous driped (30 mg/d).In this treatment schedule,every course of treatment sustained 10 days,and with a 2 weeks interval.During this process,patients in treatment group were treated with hydroxyl urea only when their WBC in peripheral blood exceed 20×109/L,otherwise,discontinue it.Treatment group (12 cases),on the first day of treatment with IFNα-2b and Ara-C,added indomethacin (25 mg) through oral administration,the frequency was t.i.d.During treatment in the two group,the end point of observation was completely hematology ease,at the same time,these indicators in the two groups needed to be compared,the time when WBC begin to fall,the time when WBC fall to normal range,the time when immature cells returned to normal,the time which complete hematological remission and the highest temperature of patients after IFNα-2b was subcutaneous injected.Results The time when WBC begin to fall in treatment group was (4.2±2.7) d,and the time was (5.0±2.5) d in control group (t =0.714,P ＞ 0.05).In treatment group,the time when WBC fall to normal range was(10.0±4.5) d,and the time was (12.0±4.5) d in control group (t =1.036,P ＞ 0.05).The time when immature cells returned to normal in treatment group was (14.2±4.8) d,and the time was (19.0±3.6) d in control group (t =2.609,P ＜ 0.02).The time which complete hematological remission was achieved in control group was (45.8±5.6) d,but it was (53.9±10.5) d in control group (t =2.314,· P ＜ 0.05).Meanwhile,the fever degree after IFNα-2b was subcutaneous injected obviously achieved improvement in treatment group (x2 =12.041,P ＜ 0.005).Conclusion The advantage of indomethacin to the unite treatment with IFNα-2b and LD-Ara-C on CML mainly lays in which cound alleviated the adverse reaction such as flu-like of IFN,and more,there are synergy effect in antagonist CML.

Objective To compare the short-term quality of life after total gastrectomy in patients with gastric cancer with three recontructive methods of stamoch storage function. Methods Totally 62 cases underwent jejunal interposition afar total gastrectomy from March 2000 to December 2007. Patients were divided into three groups according to the procedures: functional jejunal interposition (FJI-type) group ( n = 23 ), modified jejunal interposition ( Ⅲ -type) group ( n = 20), and P-type jejunal interposition (P-type) group (n = 19). In each group,the patients' general conditions, the nutritional status at month 3 and 12, and gastrointestinal symptoms were evaluated. Results The durations of procedures were significantly different among three groups (P ＜0. 01 ). The intraoperative bleeding volume, postoperative complications, and food intake of each meal at month 3 were not significantly different ( P ＞ 0. 05 ). Compared with the data at month 3, the levels of hemoglobin and serum calcium at month 12 were significantly higher in all three groups (P ＜ 0. 01 ). Compared to the level at month 3, the level of serum albumin at month 12 significantly increased in FJI-type group (P ＜ 0. 05 ) but showed not significant difference in Ⅲ-type group and P-type group ( P ＞ 0. 05 ). The incidence of reflux esophagitis in three groups and the comparative parameters among the three groups at month 12 were not significantly different ( P ＞ 0. 05 ). Conclusions The jejunal interpositions after total gastrectomy will not increase the complexity and risk of the surgical procedure. In fact, they can reduce the reflux esophagitis and improve quality of life by keeping the storage function and restoring food passage through the duodenum. FJI-type is simpler than the other two types, and P-type is preferred for operations that need to open the pectoral cavity.

Objective:To investigate and summarize the procedures of direct-covedng pancreaticojejunostomy with remaining jejunal mucosa in pancreaticoduodenectomy and to analyze the incidence of pancreatic fistula and other postoperative complications.Methods:A total of 21 patients were treated with pancreaticoduodenectomy between May 2005 and June 2009.During the surgery,we dissected 3cm long remnant of the pancreas out of ambient tissues.Near the 2.0-3.0cm of the pancreatic remnant.we fixed partial posterior wall with the full-thickness jejunum without mucosa destroyed by interrupted suture,and then pushed the remnant into the jejunum and fixed the anterior wall.Finally,at the 1.0cm of the panceratic remnant,we binded the iejunum to surround the pancreas through 7-silk sutures.Results:One case was treated with secondary surgery due to bleeding of the pancreatic remnant.The other patients recovered smoothly without pancreatic fistula or other complications.Conclusion:Postoperative pancreatic fistula is related to the texture of pancreas,method of pancreaticojejunostomy,surgical skills and perioperative treatment.Compared with other types of pancreaticojejunostomy,direct-covering pancreaticojejunostomy with remaining jejunal mucosa is simpler.

Objective To compare the incidence of recurrent laryngeal nerve (RLN) injury in thyroidectomy with or without exposing RLN. Methods Records of 704 patients in our hospital undergoing thyroidectomy were retrospectively studied, among whom 472 patients underwent thyroidectomy with RLN being exposed and 232 underwent thyroidectomy without RLN being exposed. Results The incidence of RLN temporary damage and permanent damage in RLN exposed group was 1.49% (7/472) and 0, while it was 6. 03% (14/232)and 2. 16%(5/232) in the non-exposed group. There was statistic difference between the two groups in terms of permanent injury incidence and operation duration (P ＜ 0. 01). Conclusions Although the operation duration was prolonged in RLN exposure group, RLN exposure during operation is very helpful to prevent recurrent laryngeal nerve injury. Therefore, it's necessary to expose RLN during operation in sub-total thyroidectomy and total thyroidectomy.
