OBJECTIVETo introduce an arthroscopic technique in managing recurrent dislocation of the patella and its clinical results.

METHODSSixteen patients with recurrent patellar dislocation were reviewed, including 3 males and 13 females. The average age was 17.6 years old (ranged from 14 to 32 years). The patients suffering from patellar sub-luxation averaged 18.5 months (ranged from 6 to 23 months)before operation. These patients were treated with lateral patellar retinacular release outside the synovial bursa of knee joint and medial patellofemoral ligament reconstruction using the semitendinosus tendon free autograft. The Lyshohm scores before and after operation were used to evaluate outcomes at the final follow-up.

RESULTSAll the patients were followed up, and the duration ranged from 6 to 48 months, with an average of 12 months. There was no recurrence. The Q angle decreased from (16.4 ± 3.7)° to (10.1 ± 1.4)°; insall index decreased from 1.37 ± 0.25 to 1.28 ± 0.23; congruence angle decreased from (21.3 ± 2.6)° to (5.86 ± 2.23)°; Lysholm score improved from 76.1 ± 5.2 to 89.8 ± 4.1 at 6 months after operation.

CONCLUSIONCompared with conventional procedure, arthroscopic surgery for recurrent dislocation of the patella achieves excellent outcomes with minimum invasion.

OBJECTIVETo investigate the clinical effect and safety of chiropractic in treating cervicogenic sudden hearing loss.

METHODSFrom January 2011 to October 2013, 90 patients with cervicogenic sudden hearing loss were randomly divided into treatment group and control group according to the random number table produced by SPSS 19.0 software. In the treatment group, there were 17 males and 28 females, aged from 31 to 62 years old with an average of (47.57±9.43) years; course of disease was from 1 to 3 days with an average of (1.43±0.68) days; pure-tone audiometry score was from 46.5 to 77.8 dB with the mean of (61.20±9.83) dB; Northwick Park Neck Pain Questionnaire (NPQ) score was from 17 to 31 scores with an average of (23.46±7.18) scores. In the control group, there were 15 males and 30 females, aged from 28 to 64 years old with an average of (45.77±6.99) years; course of disease was from 1 to 3 days with an average of (1.50±0.73) days; pure-tone audiometry score was from 48.1 to 75.0 dB with the mean of (63.91±8.05) dB; Northwick Park Neck Pain Questionnaire (NPQ) score was from 20 to 29 scores with an average of (25.61±10.43) scores. The patients of control group were treated with dexamethasone intravenous drip of 10 mg, 3 days later, decreased to 5 mg, 3 days again. And with the methycobal intravenous drip of 500 μg, treatment continued for 10 days. The patients of treatment group were treated with chiropractic additionally except for the therapeutic methods of control group. Chiropractic included local muscle loosening, attacking point, bilateral pulling atlanto-axial joint, and continuous treatment for 10 days. The pure-tone audiometry score and NPQ score were compared between two groups after treatment.

RESULTSAfter the treatment, pure-tone audiometry score and NPQ score in treatment group improved to (40.23± 8.14) dB and (12.70±8.29) scores respectively, which were obviously better than that of control group's (37.70±10.61) dB and (21.24±11.13) scores (P<0.05).

CONCLUSIONCompared with routine method for cervicogenic sudden hearing loss, additional chiropractic can improve hearing and relieve neck pain effectively.

Objective To observe the prevalence, awareness, treatment and control rate of hypertension and to evaluate the 10-year absolute risk of coronary heart disease (CHD) and ischemic cardiovascular disease (ICVD) in Chinese cardiovascular physicians. Methods A total of 4032cardiovascular physicians (28 to 79 years old) from 386 hospitals in 31 provinces, autonomous regions and municipalities were randomly selected and received an epidemiologic survey of prevalence, awareness, and control of hypertension and evaluations of CHD and ICVD risk. Results The prevalence of hypertension in Chinese cardiovascular physicians was 13.1%. The awareness rate of hypertension in Chinese cardiovascular physicians was 81.7%. Hypertension treatment rate was 69. 6% and blood pressure control rate was 44. 6%. The prevalence of hypertension was higher in male physicians than in female physicians before the age of 55 years old. Ten-year absolute risk of CHD and ICVD was 0. 08 and 0. 03 in hypertensive physicians compared to 0. 03 and 0. 01 in non-hypertensive physicians. Conclusions The results show suboptimal awareness, treatment and control rate in Chinese cardiovascular physicians for their own hypertension status. Physicians suffering from hypertension face higher risk for cardiovascular disease. It is therefore necessary to improve the self-monitoring of blood pressure in Chinese cardiovascular physicians.

OBJECTIVETo explore the effects of graft composition on hematopoietic reconstitution and graft-versus-host disease (GVHD) in HLA-identical related donor peripheral blood stem cell transplantation (PBSCT) for hematological malignancies.

METHODSThe relationship between the number of graft composition and their hematopoietic reconstitution and GVHD in 107 patients with hematological malignancies undergoing HLA-identical related donor PBSCT was retrospectively analyzed.

RESULTSNone of the graft composition numbers had correlation with the time of neutrophil reconstitution. There was a negative correlation between the number of mononuclear cells (MNCs) or CD34+ cells and the time of platelet reconstitution (P < 0.05) with the absolute correlation coefficients below 0.4, and so did between the number of CD34+ or CD34+ CD38- cells and the development of acute GVHD (P < 0.05) and their absolute correlation coefficients. Each lymphocyte subset number had no correlation with acute GVHD. There was a positive correlation between the number of CD25+ CD4+, CD3+ or CD4+ CD3+ cells or CD4+ /CD8+ ratio and the development of chronic GVHD (P < 0.05). And the correlation coefficients all exceeded 0.4, more over, CD25+ CD4+ cells number reached up to 0.78. CD34+, CD34+ CD38- cells number had no correlation with chronic GVHD.

CONCLUSIONIn HLA-identical related donor PBSCT, further increasing infused MNC, CD34+, CD34+ CD38- cells can no more accelerated hematopoietic reconstitution after these cells attained their threshold values, otherwise the incidence of cGVHD might increase due to the increase of the accompanied lymphocytes.

AIMTo study the fingerprint of Ezhu by GC-MS.

METHODSGC-MS analysis was performed for 18 samples of three species of Curcuma used as Ezhu. TIC profiles were evaluated by "Computer Aided Similarity Evaluation System" (MATLAB5.3 based, Ver. 1.240, developed by Research Center for Modernization of Chinese Medicine, Central South University). The characteristic peaks in chromatograms were identified by comparing mass data with literatures. Hierarchical clustering analysis was performed by SPSS based on the relative peak area (RPA) of identified peak to germacrone in 18 samples.

RESULTSResemblance values of 18 samples of Ezhu were pretty low. The mutual mode fingerprint plots of Ezhu were failed to develop. However, 18 samples were divided into two main clusters based on hierarchical clustering analysis, Curcuma wenyujin cluster and Curcuma phaeocaulis cluster, but the samples of Curcuma kwangsiensis were dispersive. Therefore, based on hierarchical clustering analysis, two mutual mode fingerprint plots of Curcuma wenyujin and Curcuma phaeocaulis were developed. But that of Curcuma kwangsiensis was failed because of low resemblance among samples.

CONCLUSIONThe mutual mode fingerprint is the basis for quality control of Chinese materia medica from multi-origins. Development of GC-MS fingerprint of Ezhu was failed, which indicates that the chemical components in different species of herbs used as one Chinese materia medica may be significantly different. The relationship of chemical components and pharmacological activities should be further studied so as to elucidate the rationality of Chinese materia medica from multi-origins.

Objective To investigate the relationship between marital status and prevalence of peripheral arterial disease (PAD) among Beijing residents.Methods From May to August 2007,10 054 residents were interviewed to collect demographic and biochemistry information.Generalized linear mixed model was used to determine the relationship between marital status and prevalence of PAD in terms of OR and corresponding 95％ confidence intervals.Results After adjusting the traditional risk factors including age,area,lipid,serum glucose,blood pressure,central obesity,smoking,drinking and physical activities for PAD,relationship between marital status and prevalence of PAD was found both at the female and male groups of those with 45 years or older.Compared with married men,OR and 95％ confidence interval of PAD for unmarried men were 1.56 (0.39 - 6.35 ) and 1.61 (0.77 - 3.35 ) for those with 45 years younger and older respectively,while compared with married women,OR and 95％ confidence interval of PAD for unmarried women were 0.75 ( 0.22 - 2.57 ) and 1.78 ( 1.23 - 2.58 ) for those with 45 years younger and older respectively.Significant differences ( all P ＜ 0.01 ) were found between married and unmarried women of 45 years or older in terms of age,waist circumstances,systolic blood pressure,fasting glucose,total cholesterol,low-density lipoprotein and smoking.Conclusions Peripheral arterial disease was related to marital status for women of 45 years or older among Beijing residents.Estrogen level and the distribution of other PAD risk factors might contribute to the observed finding.

This study was purposed to explore the feasibility of simultaneous analysis of telomere length and cell surface antigen by multicolor Flow-FISH to assess minimal residual disease (MRD) in leukemia. The telomere length in 34 leukemia patients versus 20 normal controls was compared by using Flow-FISH, and the relationship between telomere length and therapeutic effect and prognosis was analyzed preliminarily. As for those patients with follow-up samples, the changes of telomere length combined with surface antigen in different courses of disease were observed by multicolor Flow-FISH. The results indicated that the telomere length of de novo patients was significantly shorter than that of controls except the patients in chronic myeloid leukemia-chronic phase (CML-CP). The shorter telomere, the lower complete remission (CR) rates were observed in acute leukemia cases and the shorter duration of CP before onset of blast phase (BP) occurred in CML cases. The acute leukemia patients showed longer telomere and fewer cells expressed the related antigen after CR. The telomere length of cases with continued CR remained at normal level during remission, and there was no increased expression of the specific antigen. However, the telomere of relapsed cases shortened again after relapse with elevated specific antigen expression. In the relapsed cases, the telomere of related antigen positive cells shortened ahead of telomere length change of the whole cells and morphologic change of bone marrow cells. It is concluded that analysis of telomere length by flow-FISH manifests the significance for monitoring disease conditions, estimating prognosis and guiding therapy in all kinds of leukemia. The simultaneous analysis of telomere length and cell surface antigen by multicolor flow-FISH may monitor abnormal clone or clonal evolution to predict recurrence more sensitively and specifically, and may provide a promising and widely applicable method for monitoring MRD in leukemia.
