Study group Hb after treatment was (106.43±13.08) g/L, the control group after treatment Hb(98.69±14.25)g/L, there was significant difference between two groups(t=13.26,P<0.05). After treatment, study group MCV, MCH, MCHC improvement, compared with the control group with statistical significance; the two groups in the improvement of red blood cell morphology were obvious effect, and the study group was better than control group. Statistical significance of group SF after treatment and the control group at the same time difference(t=11.28,P<0.05). The control group had 10 cases of gastrointestinal discomfort, study group 1 cases of no adverse reaction.Conclusion: TCM symptoms of Chinese medicine Yiqi Buxue cream treatment can significantly improve the syndrome of blood deficiency of iron deficiency anemia, reduce the number and the number of red blood cell transfusion, clinical curative effect, less adverse reaction.

Objective To analyze the clinical characteristics and therapy of levofloxacin-induced prolonged Q-T interval in patients with multi-drug resistant tuberculosis ( MDR-TB) . Methods Clinical materials of 6 patients with MDR-TB who developed prolonged Q-T/QTc interval caused by levofloxacin therapy were analyzed. Those cases were collected from the Tuberculosis Prevention and Control of Wuhan City form April 2010 to August 2014. Results The proportion of patients with levofloxacin-induced prolonged Q-T interval was approximately 3.0%.The condition occurred 2-8 months after the administration. The initial value of QTc interval ranged from 397 ms to 439 ms, while the average was (410.17±14.62) ms.The value of QTc interval was extended to 470-486 ms after treatment of levofloxacin, while the average was (476.33±6.16) ms.The increase of QTc interval was 47-85 ms, while the average was ( 66 ± 11. 48 ) ms. None of them developed Tdp. Conclusion The application of high dosage and long treatment course of levofloxacin in patients with MDR-TB could result in the extension of the Q-T/QTc interval, which should arouse our serious attention. In order to detect the abnormal Q-T/QTc interval in early stage, electrolyte level examination as well as ECG examination should be considered as routine tests before initiation of treatment and during the follow-up treatment.

AIM:Xilei Powder,a traditional Chinese prescription,has been used to treat wounds for hundreds of years,but the mechanism has not been fully understood.METHODS:The effects of Xilei Powder on fibroblast proliferation,collagen accumulation,matrix metalloproteinases-2,9 ( MMP-2,9 ) activities and tissue inhibitor of metalloproteinase 1 (TIMP-1) production were investigated by MTT,chloramine T method,gelatin zymography and enzyme-linked immunosorbent assays ( ELISA),respectively.RESULTS: The aqueous extract of Xilei Powder significantly promoted fibroblasts proliferation in a time and concentration manner,the population doubling time (125 μg/mL) was 33.8 h,it also significantly (P ＜0.05 ) promoted collagen production.Both of the aqueous and alcoholic extracts could significantly ( P ＜ 0.05 ) increase MMPo2 activity,and also very significantly ( P ＜ 0.01 )promote TIMP-1 production.CONCLUSION: Xilei Powder could promote fibroblasts proliferation,collagen and TIMP-1 production,this might be parts of mechanism to promote wound healing.

Objective To investigate the characteristics and relative pathogenesis of cognitive impairment in people with depression.Methods 24 people with depression and 24 healthy controls were evaluated respectively with HAMD scale,the WCST test,N-BACK task P300 and fMRI.Results (1) The WCST scores,N-back reaction (MRT),the P300 incubation period in depression group were significantly different from those in control group(P300 wave amplitude(4.12± 1.51) μV vs (6.42± 1.73) μV ; P300 latency(392.02±23.60) ms vs (309.43± 21.39) ms,t=4.922,P＜0.01 ; t=12.726,P＜0.01).(2) The illness course had positive correlation with Rep(r=0.596,P＜0.01) and mRT(r=0.518,P＜0.01).The P300 latency had positive correcation with Rpe(r=0.929,P＜ 0.01) and mRT(r=0.939,P＜0.01).(3)Compared with control group,the decreased activation area in patients with depression were as follows:bilateral frontal gyrus,left middle frontal gyrus,inferior frontal gyrus and superior parietal lobule.Conclusion The depressive patients exist cognitive impairment mainly in frontal lobe.The longer with the illness,the wose with the impairment.P300 incubation period is a sensitive indicator of the frontal executive function.

Background Orbital fracture in children has its own characteristics.Choosing the suitable plastic materials is the effective measurement to improve the successful rate of surgery.Absorbable plate filling provides a new material for children with orbital fracture.However,few studies compare the effectivity and safety between absorbable plate filling and conventional filling.Objective The aim of this study was to compare the longterm efficacy and safety between absorbable plate and Medpor implants in the repair of pediatric orbital fracture.Methods Clinical data of 72 eyes of 72 pediatric patients with orbital fracture who received surgicals reconstruction in Beijing Tongren Eye Center from 2008 April to 2014 August were respectively analyzed,including 28 patients with absorbable plates filling and 44 patients with Medpor implants.Demography and preoperative clinical signs were matched between the two groups.Operative procedure was same except the implanted materials.The functional training of extraocular muscle was performed since the second day after surgery in both groups.The imaging findings of the orbit were evaluated by computed tomography (CT) before and after surgery.The patients were followed-up for avarage 12.7 months after operation.The therapeutic effectiveness and safety were compared between the different implants,such as incidence of enophthalmos,extraocular movement impairment and diplopia,and the sensory deficit of skin and complications were documented.Results Extraocular muscle movement improved and diplopia alleviated or disappeared in 92.9％ (26/28) in the absorbable plate group and 90.9％ (40/44) in the Medporgroup,without significant difference between the two groups (P=0.57).The sensory deficit of skin was found in 13 eyes (46.4％) and 20 eyes (45.5％ in the absorbable plate group and Medpor group,respectively,and there was no significant difference between the two groups (P =0.56).CT revealed that the anatomical reconstruction of orbits could be achieved in all patients in both groups without the shifting of implants and extrusion.No enophthalmos and postoperative infection were found in absorbable plate group,however,the residual enophthalmos or late infection was found in I eye for each in the Medpor group.Conclusions Both the absorbable plate and Medpor implants show good results for reconstruction of pediatric orbital fracture.Absorbable plate is an ideal material for pediatric orbital blowout fracture because of fewer postoperative complications.

Objective To investigate the clinical value of tissue polypeptide specific antigen(TPS),neuron-specific enolase(NSE),carcinoembryonie antigen(CEA)and CA125 in serum of small cell lung cancer(SCLC)patients and its significance in diagnosis and disease monitoring.Methods Serum leveh of TPS was detected using ELISA and serum levels of NSE,CA125 and CEA was detected using ECLin 27 1 SCLC patients.80 pulmonary benign disease patients and 224 normal healthy people.Diagnostic values of these tumor markers were analyzed by receiver operative characteristic(ROC)curve.Results The levels of TPS,NSE,CA125 and CEA iu the serum of SCLC group were signifieanfly higher than those in pulmonary benign disease and healthy group(Z＞1.90,P＜0.01).The levels of TPS and NSE in the serum of extensive stage small cell lung cancer(ESCLC)patients were significantly higher than those in limited stage small cell lung cancer(LSCLC)(Z=2.69,2.27,P=0.009,0.02 respectively).,The level of TPS and NSE showed statistical significance among SCLC patients with different prognosis after therapy(Z=4.06,3.11.P=0.001,0.007 respectively).The TPS+NSE showed the highest sensitivity of 86.7%,and the specificity,PPV and NPV were 75.0%,81.0% and 82.2%,respectively.Conclusions Serum levels of TPS,NSE,CA125 and CEA are useful for SCLC diagnosis.TPS+NSE shows the highest clinical values in SCLC diagnosis and prognosis.

Objective To study the diagnostic value of double-balloon endoscopy (DBE) and capsule endoscopy (CE) for small intestinal bleeding. Methods Overall detection rates of small intestinal bleeding with DBE, CE and the whole alimentary tract barium meal were compared. Positive rates of bleeding detection with DBE and CE were compared within the same patients. Influence of CE on one-procedure rate of DBE was analyzed. Results In 105 cases of small intestine bleeding, DBE detected 24 cases of Crohn's disease, 15 adenocarcinoma, 12 chronic nonspecific inflammation, 10 small intestinal ulcer of unknown reason, 8 entero-mesenchymoma, 8 polypus, 6 vascular deformation hemorrhage, 5 ancylostomiasis, 5 Mechel's diverticula ( including multiple diverticula), 3 lymphoma and 9 of no evident abnormalities. The positive detection rate of DBE is 91.4% (96/105). Disease detection rates of CE and whole alimentary tract barium meal were 75.0% (30/40) and 33.3% (25/75), respectively. The one-procedure rate of DBE is 90% (36/40) based on CE results, but it was only 69. 2% (45/65) according to clinic features and the whole alimentary tract barium meal. Conclusion The main causes of small intestinal bleeding are benign ulcers (including Crohn's disease) and tumor, as well as chronic inflammation. Polyps, vascular deformation, parasitosis, Mechel's diverticulum and lymphoma are the secondary causes.DBE is superior to CE in diagnosis of small intestine bleeding, but CE can increase the one-procedure rate of DBE.

Objective To investigate the clinical features,diagnosis and treatment of appendix tumor.Methods The clinical data of 58 cases with primary appendiceal tumor were analyzed retrospectively.Results In the 58 cases clinical presentation mimicked acute appendicitis in 22 cases,chronic appendicitis in 15 cases,appendiceal abscess in 12 cases,intra-abdominal mass in 7 cases,and gastrointestinal perforation in 2 cases.Primary appendiceal tumor was diagnosed intraoperatively by intraoperative frozen histopathological examination in 10 cases,and the diagnosis was made by postoperative histopathological examination in the other 48 cases.There was appendiceal carcinoid in 40 cases,adenocarcinoma in 6 cases,mucocele in 2 cases,mucous adenocystoadenoma in 5 cases,pseudomyxoma peritonei in 2 cases,malignant neurilemmoma in 1 case,and malignant lymphoma in 2 cases.Surgical procedures included appendectomy in 6 cases,ileocecal resection in 8 cases,and right hemicolectomy in 44 cases (including right hemicolectomy and intraperitoneal chemotherapy with 5-FU 1 000 mg for pseudomyxoma peritonei in 2 cases).Radical resection was achieved in 55 cases and palliative resection in 3 cases.The 2 cases with pseudomyxoma peritonei died of tumor recurrence at 36 months and 54 months after operation respectively.All the 5 cases of adenocystoadenoma and 2 cases of appendix cyst survived without an evidence of recurrence.7 of 49 cases of malignant appendiceal tumor suffered recurrence postoperatively,the recurrence rate was 14％,which included liver metastasis in 4 cases and intraperitoneal recurrence in 3 cases.The 1,3,5-year survival rates of malignant appendiceal tumors were 100％ (49/49),92％ (35/49) and 80％ (39/49),respectively,which were 100％,98％ and 92％ for carcinoid,and 100％,67％ and 33％ for adenocarcinoma,respectively.Conclusions The preoperative diagnosis of primary appendiceal tumor is very difficult,the intraoperative frozen histopathological examination is helpful for diagnosis,the prognosis of appendiceal carcinoid is fair after resection.

Objective: To investigate the knowledge, attitudes and practice of AIDS control knowledge among students in a university in Hangzhou City, so as to provide the evidence for evaluating the effectiveness of AIDS control in universities. Methods: The knowledge, attitudes and practice towards AIDS control were investigated among students in a university in Hangzhou City using self-designed questionnaires in 2020, and were descriptively analyzed. Results: Totally 6 300 questionnaires were allocated, and 6 164 valid ones were recovered, with an effective recovery rate of 97.84%. The respondents included 2 837 male students ( 46.03% ) and 3 327 female students ( 53.97% ), and had a mean age of ( 18.20±0.76 ) years. The overall awareness of AIDS control knowledge was 73.49%. The awareness rates of “The rights of marriage, employment and school admission are protected among HIV-infected individuals by Chinese laws” ( 61.11% ) and “Homosexual contact in men is the current main transmission pattern among young students in China” ( 66.37% ) were relatively low. There were 768 university students with a history of sexual behaviors ( 12.46% ), and regular sex partners were the predominant sex partners at the first sexual contact ( 679 students, 90.78% ) and at the sexual behaviors during the past one year ( 402 students, 71.91% ). There were 515 students (67.14%) using condoms during the first sexual contact, and there were 300 ( 63.83% ) and 16 students ( 40.00% ) using condoms with regular and casual sex partners during the past one year, respectively. Among 20 men who had sex with men, only 5 students ( 25.00% ) used condoms at each sexual contact. Of students with sexual behaviors, there were 355 (46.22%) and 354 ( 46.09% ) students that considered to be infected with AIDS and other sex-transmitted diseases, and among the university students with sexual behaviors, there were 614 ( 79.95% ) students that were willing to receive HIV testing, and 409 ( 53.26% ) and 305 ( 39.71% ) students that were willing to receive HIV testing in hospitals and disease control and prevention institutions, respectively. Conclusions The awareness of AIDS control knowledge is low among students in the university in Hangzhou City, which does not reach the national goal of supervision and assessment for AIDS control in China. There are high-risk sexual behaviors and the rate of condom use is low.
