Objective To study the factors affecting the functional restoration of the hip joint with femoral intertrochanteric fractures.Method44 patients with femoral intertrochanteric fractures were treated from Aprail 2004 to June 2006.The function of the hip joint was evaluated with the Harris hip score. Seven factors including age,sex,preoperative ASA class,preoperative time,fracture type,therapeutic measures,time of functional exercise were analyzed statistically with x2 test and logistic multiple regression with a significant difference (P

[Objective]To explore the mechanism of nucleoplasty combined with oxygen-ozone for the treatment of lumbar disc herniation，and to evaluate its therapeutic effects.[Method]From June 2005 to June 2006，62 patients with lumbar disc herniation were treated by nueleoplasty combined with oxygen-ozone，34 were male and 28 were female，ranging in age from 32 to 76 years，with an average of 53.4 years.The course of this disease ranged from 3 to 56 months，meanly 1.3 years.Thirteen patients had the herniation at L4.5 and L3，4，thirty two patients at L4、5，eight patients at L4、5 and L5S1，and nine patients at L5S1.The curative effect was assessed by using a modified MacNab method.[Result]After 25～35 months'follow-up，there were no servious complications in all 62 cases.According to modified MacNab assessment，50 cases(80.7%)achieved excellent outcomes，8 cases(12.9%)good，2 cases(3.2%)fair and 2 cases(3.2%)poor.The excellent and good rate was 93.5%.[Conclusion]The micro-invasive technique of nueleoplasty combined with oxygen-ozone is effective in the treatment of lumbar disc herniation，and it has maximized the clinical effect and minimized the local damage：it also expanded adaptive cases with lumbar disc herniation and enlarged the applicable scope of minimally invasive technique in treating lumbar disc hemiation.

A retrospective analysis was performed among 8 patients with unilateral intraarticular calcaneal fracture, who were selected from the Department of Orthopaedics in Yangpu District Central Hospital of Shanghai. They were treated with the injectable bone graft MIIG[R] X3 combined with percutaneous reduction by leverage and axial fixation from June 2005 to November 2006. After treatment, the function of affected feet was evaluated according to the ankle-hindfoot score of the American Orthopaedic Foot & Ankle Society (totally 100 points). All the patients were rechecked with X-ray films periodically to observe the reaction between the materials and the host, the healing of fracture, the pain of limbs and joint motion. Eight patients were all followed up, the complication rate reached 12.5% (1/8), the improvement of Bohler angle excelled 18° to 25°, and that of Gissane angle exceeded 30° to 35°. Among the included patients, 6 cases achieved excellent effect and 2 cases good. All developed the bone union. None of all had complications, such as necrosis of skin, hematoma and deep infection.

Objective To explore the effect of magnesium sulfate combined with calcium channel blockers on cystatin C, uric acid, alpha fetal protein and urinary transferrin in patients with hypertension pregnancy.Methods 75 cases with hypertension of pregnancy were selected and divided into two groups, control group(n=37) were treated with conventional therapy, experiment group(n=38) were treated with magnesium sulfate combined with calcium channel blockers on the basis of control group.Cystatin C, uric acid, alpha fetal protein and urinary transferrin were compared after treatment between two groups.Results Compared with control group, Cys C, uric acid, serum AFP l, urinary TRF levels were all lower in experiment group( P<0.05), serum hematocrit, whole blood viscosity and erythrocyte aggregation index were all lower in experiment group(P<0.05).The total efficiency of experiment group was significantly higher than control group (P<0.05).Conclusion Magnesium sulfate combined with calcium channel antagonists in treatment of hypertensive disorder complicating pregnancy patients has good clinical curative effect, can effectively improve blood viscosity, reduce serum Cys C, UA, AFP and urinary TRF level.

Objective To explore the change and significance of blood lipid and oxidative stress in subchnical hypothyroidism during pregnancy.Methods 100 pregnant women with subclinical hypothyroidism during pregnancy were chosen and set as the disease group,while 100 healthy pregnant women were chosen and set as the control group.Thyroid function index:free three iodine thyroid original glycine (FT3),free thyroid hormones (FT4),thyroid stimulating hormone (TSH),blood lipids index:triglyceride (TG),total cholesterol (TC),high density lipoprotein cholesterol (HDL-C),low density lipoprotein cholesterol (LDL-C),and oxidative stress indicators:superoxide dismutase (SOD),malondialdehyde (MDA),type oxidized low density hpoprotein (ox-LDL) in the two groups were detected and analyzed.Results FT3 and FT4 between the two groups had no statistical significance (P＞0.05).TSH in the disease group was (4.63±1.09) mIU/L,significantly higher than that of the control group(P＜0.05).The comparison of TG,HDL-C between the two groups had no statistical significance(P＞0.05).TC and LDLC in the disease group were significantly higher than those of the control group (P＜0.05).MDA and ox-LDL in the disease group were significantly higher than those of the control group,while SOD was significanTLy lower than that of the control group(P＜0.05).Conclusion Subclinical hypothyroidism during pregnancy can cause metabolic disorder of blood lipid and reduce oxidative stress ability.Monitoring and intervention of blood lipid and oxidative stress status is necessary.

Objective To study the clinical significance of apolipoprotein B and apolipoprotein A1 ratio (ApoB/ApoA1) in patients with polycystic ovary syndrome (PCOS) combined metabolic syndrome (MS),by detecting the level of ApoB and ApoA1 in patients' serum.Methods 160 patients with PCOS were selected in our hospital from Jan.2014 to Dec.2015,and they were divided into MS group and non-MS group according to the diagnostic criteria of MS.The anthropometric measurements,endocrine markers,glucose and lipid metabolism indexes of patients in the two groups were measured and compared.Correlation of ApoB/ApoA 1 ratio and components of MS were analyzed,respectively.Relationship between ApoB/ApoA1 ratio and the number of abnormal components in MS were also investigated.Results Significant difference was found in the levels of ApoB ((1.01±0.34) g/L) and ApoA1((1.15±0.29) g/L) between MS group and non-MS group (P＜0.05),and ApoB/ApoA1 ratio in MS group was obviously higher than that in non-MS group (P＜0.05).ApoB/ApoAl ratio was positively correlated with BMI,waist circumference (WC),systolic blood pressure (SBP),diastolic blood pressure (DBP),fasting plasma glucose (FPG),insulin resistance index (HOMA-IR),high triglycerides (TG) and low density lipoprotein (LDL-C),respectively,and it was negatively correlated with high density lipoprotein (HDL-C)(P＜0.05).However,there was no significant correlation between ApoB/ApoA1 ratio and the age,fasting insulin (FINS),as well as the total cholesterol (TC) (P＞0.05).Moreover,ApoB/ApoA1 ratio increased with increase in the number of abnormal components (P＜0.05).Conclusion ApoB/ApoA1 ratio is closely related to the components of MS,and it may have important clinical significance for diagnosis of PCOS combined MS and preventing long-term complications of PCOS.
