Objective To investigate the management of ankle fracture with surgery and postoperative rehabilitation.Methods The data of 39 inpatients with ankle fracture from 2001 to 2005 were analyzed retrospectively. All patients were treated surgically with open reduction and internal fixation (ORIF) except one medial ankle fracture with closed reduction. All patients were encouraged to perform active and passive range of motion exercises of ankle and the involved limb on the 2nd day after surgery, and partial weight-bearing was allowed at 4th week after surgery.Results No patients had wound-healing problems and deep venous thrombosis, no significant calf muscle atrophy exist at discharging. 29 patients showed excellent ankle joint function and normal gait when the internal fixation was removed at an average 17.9 postoperative months.Conclusion The surgery combined with early rehabilitation used for ankle fracture can improve the recovery of ankle function.

Based on variation of Pinus massoniana families, heritablility and correlation analysis, the contents of shikimic acid and procyanidine (heritability 0.90, 0.70), dry weight of single branch (heritability 0.60) and and leaf length (heritability 0.46) were screened out as quality, yield and harvest cost traits of Folium Pini, respectively. For the different medicinal application of Folium Pini, varied methods were chosen to estimate weight and construct index equation. Weight adjustment based.on equal emphasis were used as economic weight determining method to select the best families, and the index (accuracy 0. 936 4 and heritability 0. 881 6) obtained was a little better than that obtained by equal emphasis, and much better than that by restricted index. The superior families selected with adjustment weight and equal emphasis were No. 46, 43 and 28. Partial regression were used as economic weight determining method to select the best families,and the index obtained had the highest accuracy (0.941 5) , index heritability (0. 889 9) and the genetic gain of shikimic acid content. The superior families selected with this method were No. 46, 27 and 47. No. 46 was the best families with maximal economic benefit. Our study indicated that suitable method for estimate weight and construct index equation can be applied for better accuracy of superior families selection of P. massoniana.

BACKGROUND: Unicompartment knee arthroplasty (UKA) is gradually applied in the treatment of knee osteoarthritis, and the management of perioperative blood loss is a hot spot in clinical research. It is very important to control perioperative blood loss and changes in hemoglobin level for postoperative rapid recovery. OBJECTIVE: To investigate the changes in the blood-related indexes during the management of perioperative blood loss in UKA, so as to provide technical reference and data reference for clinical application. METHODS: Clinical data 70 patients undergoing UKA at the Department of Bone and Joint of Guangdong Provincial Hospital of Chinese Medicine from January to December 2015 were analyzed retrospectively, and received the management of perioperative blood loss. The operation time, intraoperative blood loss, postoperative drainage volume, total blood loss and rate of blood transfusion were recorded; the preoperative hemoglobin, albumin, coagulation indexes, D-dimer, erythrocyte sedimentation rate and C-reactive protein were investigated. The effect of operation on the postoperative blood loss and drainage volume was analyzed. RESULTS AND CONCLUSION: (1) The operation time was (89.36±19.89) minutes, intraoperative blood loss was (39.71±23.64) mL, postoperative drainage volume was (56.21±34.21) mL, and rate of autologous blood transfusion was 0. (2) The operation time exerted no effect on the intraoperative blood loss (P=0.685 7), but affected on the postoperative drainage volume (P=0.021 6). (3) The total postoperative blood loss was little, and the blood loss did not differ significantly at 3 hours, 1, 3 and 7 days postoperatively (P > 0.05). (4) There was a slight decline in hemoglobin on days 1-3 after surgery, and then returned slowly; the erythrocyte sedimentation rate and C-reactive protein increased rapidly within 1 day after surgery and declined within 1-3 days; the D-dimer rapidly increased on day 1 after surgery, then rapidly decreased on days 1-3, and then slowly increased on days 3-7; the plasma total protein and albumin were stable and fluctuated in the normal range within 1-3 days. (5) These results suggest that the UKA had short operation time, few total blood loss and slight fluctuation, and the blood-related indexes exhibit different fluctuations. Moreover, the preoperative management of blood loss can reduce the total blood loss and rate of blood transfusion..

BACKGROUND: Periprosthetic infection after total knee arthroplasty (TKA) has become the most serious complication. However, there is still a lack of clinical study on the distribution of pathogenic bacteria. Therefore, understanding the distribution characteristics of the main pathogenic bacteria is critical for preventing and treating OBJECTIVE: To analyze the bacteriological characteristics in the patients with periprosthetic joint infection following TKA, so as to provide reference for early prevention and treatment. METHODS: CNKI, VIP, WanFang and PubMed databases were retrieved for the literature concerning periprosthetic infection following TKA published before 2016. The incidence of periprosthetic joint infection after TKA was statistically analyzed. RESULTS AND CONCLUSION: (1) 103 articles were included, involving 1 399 patients. (2) The main pathogenic bacteria were Staphylococcus aureus,coagulase negative Staphylococcus aureus,Staphylococcus epidermidis,Escherichia coli, Streptococcus and Enterococcus.There is no significant difference in the distribution of bacteria at home and abroad. Treatment strategies are divided into conservative and surgical treatments. (3) The key for successfully preventing and treating periprosthetic infection after TKA lies in the multiple disciplinary team collaboration, understanding the distribution of bacteria, early diagnosis and active preventive measurements, as well as rational treatment strategies.

OBJECTIVETo investigate the expression of PTEN (phosphatase and tension homology deletion on chromosome 10, PTEN) and its pseudogene PTENP1 in acute leukemia (AL) and correlation between them, and to explore the role of PTENP1 on the PTEN expression in AL cells.

METHODSPTEN and PTENP1 mRNA expression were evaluated in bone marrow (BM) samples from 138 newly diagnosed AL patients and 15 healthy controls by quantitative real-time RT-PCR (qRT-PCR). pCDH1-PTENP1 3'UTR-GFP lentivirus vectors were constructed. 293T cells were transfected by calcium phosphate precipitation to produce retrovirus. HL-60 cell line was infected with the retroviral vectors expressing pCDH1-GFP and pCDH1-PTENP1 3'UTR-GFP respectively. The flow cell sorter was used to sort the HL-60 with GFP positively expressed. The mRNA expression of PTEN and PTENP1 was detected by qRT-PCR, the expression of PTEN protein by western blot, and the impact of PTENP13'UTR on the proliferation of HL-60 cells by MTT assay.

RESULTSAML patients showed significantly lower PTEN and PTENP1 mRNA expression in BM compared to healthy controls. Correlation analysis showed that the expression of PTEN and PTENP1 mRNA were positively correlated (P < 0.05). The 108 cases of PTENP1(+) AML were classified according to the prognostic classification of 2011 NCCN Clinical Practice Guidelines in AML, there was no difference among different subgroups. HL-60 cell line was infected with the retroviral vectors expressing pCDH1-GFP (control group) and pCDH1-PTENP1 3'UTR-GFP respectively. Compared with the control group, PTENP1 mRNA level of HL-60 infected with the retroviral vectors expressing pCDH1-PTENP1 3'UTR-GFP increased significantly, and PTEN mRNA level also increased. While the PTEN protein level and the cell growth rate of the PTENP1 3'UTR group didn't change significantly.

CONCLUSIONPTEN and PTENP1 mRNA expression level of BM cells from AL patients is significantly lower. There is a positive correlation between expression of PTEN and PTENP1 mRNA. PTENP1 may regulate the expression of PTEN in mRNA level.

OBJECTIVETo investigate the effect of DDD pacing on vasovagal syncope (VVS).

METHODSEleven patients diagnosed VVS (7 with heart inhibiton type, 4 with combination type)by tilt table test (TTT) in Shanghai Chest Hospital were selected into the study. They all were implanted DDD pacemaker in whom 9 with rate-drop response (RDR) function. All of them were prescribed beta-receptor blocker. The patients were followed-up at 1, 3, 6, 12, 24 months after being discharged.

RESULTSAll the 11 patients with pacemaker implantation were free from syncope, in whom 4 still had pre-syncope discomfort, but the symptoms were slightly. Six patients took TTT again after pacemaker implantation. It was observed that pacing at an elevated rate started immediately when heart rate dropping to the lower threshold, and as a result syncope were prevented.

CONCLUSIONIn the VVS patients with recurrent syncope and severe heart inhibition, DDD pacing with RDR function could prevent from syncope efficiently.

OBJECTIVETo investigate the expression of placenta-derived RASSF1A gene in maternal plasma during first and second trimesters, and to explore its value for the prediction of pre-eclampsia.

METHODSFor 325 pregnant women of the first trimester, free DNA of plasma samples was extracted at 7-12, 13-18, and 19-24 gestational weeks, respectively. Methylation-sensitive restriction enzyme digestion followed by fluorescence quantitative PCR (MSRE+ PCR) was employed for analyzing the concentrations of hypermethylated RASSF1A gene. Blood pressure, proteinuria and clinical feature were monitored at the same time. Those who had subsequently developed pre-eclampsia were selected as the pre-eclamptic group, 30 normal pregnant women were selected as the control group. Hypermethylated RASSF1A gene in maternal plasma was retrospectively analyzed. The relationship between clinical classification, type of pre-eclampsia and concentrations of the gene were further analyzed.

RESULTSTwenty-six out of the 325 pregnant women developed pre-eclampsia as their only complication. At 13-18 gestational weeks, the mean concentrations of fetus-specific RASSF1A sequences were 141.62 copies/mL in maternal plasma of pre-eclamptic pregnancies, which was significantly greater than that of the controls (98.90 copies/mL). Fetus-derived RASSF1A levels were 2.03 fold higher in pre-eclamptic subjects than controls at 19-24 gestational weeks. There was a significant difference in the level of hypermethylated RASSF1A gene between the mild and severe pre-clamptic subjects at 13-24 gestational weeks (P< 0.05). The concentrations of the sequences were significantly higher in early-onset severe pre-eclampsia than late-onset severe pre-eclampsia at 19-24 gestational weeks (P< 0.05).

CONCLUSIONAltered expression of hypermethylated RASSF1A gene may be detected in maternal plasma during second trimester, which has important significance for early prediction of pre-eclampsia.

OBJECTIVETo explore the prevalence and associated factors of anxiety and depression symptoms in hospitalized Chinese patients with coronary artery disease (CAD).

METHODSFrom June 2007 to May 2009, 1083 hospitalized patients with confirmed coronary artery disease were recruited in this study. The ZUNG Self-rating Anxiety Scale (SAS) and the ZUNG Self-rating Depression Scale (SDS) were used for the psychological assessment. Economic status, living condition and the environment of both living and working places were evaluated by epidemiological questionnaires.

RESULTSThe prevalence of pure anxiety, pure depression symptoms and the combination of anxiety and depression symptoms were 7.9%, 28.3% and 14.3% respectively. Incidence of anxiety and depression symptoms was significantly higher in female patients compared with in male patients (P = 0.003, 0.012 respectively) and in aged patients than in middle-aged patients (P = 0.001). The elderly, less than 9 years of education and poor sleep quality increased the risk of anxiety symptom with ORs of 1.63 (95%CI: 1.21 - 2.21), 1.54 (95%CI: 1.15 - 2.07) and 1.62 (95%CI: 1.34 - 1.96), respectively, while workplace noise, history of chronic disease and poor sleep quality increased the risk of depression symptom with ORs of 1.52 (95%CI: 1.18 - 1.98), 1.36 (95%CI: 1.06 - 1.75) and 1.27 (95%CI: 1.08 - 1.50), respectively. Female (OR = 1.91, 95%CI: 1.22-2.98), aged patient (OR = 1.84, 95%CI: 1.23 - 2.76), workplace noise (OR = 1.61, 95%CI: 1.07 - 2.42), history of chronic disease (OR = 1.84, 95%CI: 1.24 - 2.71) and poor sleep quality (OR = 1.73, 95%CI: 1.35 - 2.21) were significantly correlated with the combined incidence of anxiety and depression symptoms.

CONCLUSIONAround half of the Chinese hospitalized CAD patients were complicated with various degrees of anxiety and/or depression symptoms. Female and aged patients were at higher risk for anxiety and depression symptoms. Sleep quality, workplace noise, years of education and history of chronic disease were independent risk factors for anxiety or depression symptoms.

OBJECTIVETo explore the quality of life among people living with HIV/AIDS (PLWHA) and analyze the influencing factors in Kunming.

METHODSA cross-sectional survey was conducted from March to April in year 2011, and 247 PLWHA were selected by convenience sampling from Yunnan CDC, Yunnan and Kunming infectious disease hospitals. General questionnaires, the simplified Chinese edition of medical outcomes study-HIV health survey (MOS-HIV, including 11 dimensions) and Social Support Scale were used. t test and multivariable linear regression model were used to analyze the results.

RESULTSFor the subjects investigated, the age was (39.8 +/- 11.9) years old, the median (quartile) value of symptoms related to HIV infection was 1(2). As to the scores of quality of life measured by MOS-HIV, physical summary score was 47.4 +/- 11.2, mental summary score was 43.6 +/- 9.7; for the scores of 11 dimensions of the MOS-HIV,that were general health (42.9 +/- 19.9), physical function (79.4 +/- 24.9), role function (59.8 +/- 48.2), social function (67.0 +/- 33.6), cognitive function (71.0 +/- 25.4), pain (81.3 +/- 26.2), mental health (62.0 +/- 22.3), vitality (49.3 +/- 23.8), health distress (74.4 +/- 21.0), quality of life (51.8 +/- 21.1), health transition (49.0 +/- 29.8). The total score of social support was 28.6 +/- 7.6, of which the score of subjective social support was 17.2 +/- 6.3, the score of the objective social support was 5.9 +/- 2.2; the score of the utilization of social support was 5.5 +/- 1.9. Multivariable linear regression analysis showed that the more the symptoms related to HIV infection, the lower the physical summary scores (standardized coefficients b' = -0.22), the general health (b' = - 0.31), the physical function (b' = -0.16), the role function (b' = -0.23), the pain (b' = -0.21), the mental health (b' = -0.22), the vitality (b' = -0.22) and the health distress scores (b' = - 0.24) (all P values < 0.05); the older the age, the lower the physical summary scores (b' = - 0.16), the mental summary scores (b' = - 0.16), the physical function (b' = -0.26), the vitality (b' = -0.26) and the quality of life scores (b' = -0.17) (all P values < 0.05); the higher the score of the subjective social support,the higher the physical summary scores (b' = 0.26), the mental summary scores (b' = 0.22), the general health (b' = 0.27), the social function (b' = 0.26), the mental health (b' = 0.15) and the quality of life scores (b' = 0.22) (all P values < 0.05); the higher the score of the utilization of social support, the higher the physical function (b' = 0.16) and the health transition scores (b' = 0.31) (all P values < 0.05).

CONCLUSIONPLWHA in Kunming have relatively lower scores of quality of life. A large number of symptoms during infection, older age and lower score of subjective social support were the hazard factors of quality of life in PLWHA.
