In recent years, pharmacological researches of Chinese medicine found that single Chinese medicines of tonifying kidney, such as epimedium, psoralen, eucommia, dipsacus, cistanche, velvet, curculigo and cynomorium had very good effects of resisting osteoporosis, significantly improving the bone mineral density (BMD) and bone mineral content (BMC) , promoting hone formation, and preventing bone absorption. Based on the documentations from home and abroad, the overview had analyzed the current situation for providing new ideas and methods of osteoporosis prevention and treatment.

Objective To analyze causes for complications after proximal femoral intramedullary nail treating unstable femoral intertrochanteric fractures in the elderly.Methods A total of 172 cases of unstable intertrochanteric fractures treated with proximal femoral intramedullary nail from December 2001 to May 2007 were reviewed upon postoperative complications to find out the causes for complications and discuss countermeasures.Results Of all, 149 cases were followed up for 6-42 months(mean 18. 5 months), which showed excellence rate of 89. 0% in aspect of functional recovery of the hip. Postoper-ative systemic complications occurred in 26 cases and local complications in 21.Condusions Proxi-real femoral intramedullary nail can be used in most elderly patients with unstable intertrochanteric frac-tures. A thorough evaluation of physiological function, treatment of preoperative comorbidities and aug-mentation of surgical technique are prerequisites for operation safety and decrease of complications.

Objective To study the characteristic and influential factor of the hidden blood loss after total knee arthroplasty (TKA) so as to provide a reference frame for clinical work. Methods There were 75 patients with osteoarthritis of the knee who were operated with unilateral primary TKA. The patients including 21 males and 54 females at a mean age of 68.7 years were retrospectively analyzed.The perioperative blood loss and the hidden blood loss following TKA were calculated by Gross formula. It was analyzed that if the perioperative blood loss and the hidden blood loss following TKA were affected by gender, haemostasis during operation with deflating tourniquet and reinfusion of the drained blood. Results The preoperative blood loss was (1551.3 ± 369.6) ml and the hidden blood loss was (792.3 ±228.6) ml. The hidden blood loss of male was significantly higher than that of female (P ＜ 0.05). The hidden blood loss was reduced by haemostasis during operation with deflating tourniquet (P ＜ 0.05) but was not affected by postoperative shed blood reinfusion. Conclusions The lowest value of Hct is a representative parameter for calculation of the hidden blood loss. There is no significant difference between male and female about the relative hidden blood loss. Haemostasis during operation with deflating tourniquet can reduce teh hidden blood loss but not affect the total perioperative blood loss. Reinfusion of the drained blood can reduce the transfusion rate but does not affect the total preoperative blood loss and the hidden blood loss.

Objective To design technique of local flap transposition to refine the aesthetic appearance of reconstructed fingers by toes transfer.Methods Nine cases with 21 reconstructed finger were included,which involved 6 males and 3 females with an average age of 21.8 years(range,18-34years).A lingual contour flap with a lateral pedicle Was shifted from the inflated distal pulp to the narrow middle part of the"finger"to refine the aesthetic appearance.Overall results were evaluated in terms of the survival of the flap,the appearance improvement and the functional influence of the reconstructed finger.Results All of the flaps survived and healed perfectly.After a mean follow-up of 9.3 months(range,6-12months),the appearance of the reconstructed fingers were impmved apparently.There was little influence on the function of the finger.The results showed that all the patients gained more acceptable fingers.Conclusion From our experience,local flap transposition is a useful method for remolding of reconstructed fingers by toes transfer.

Objective:To investigate the outcomes of applying microvascular anastomotic coupling de-vices in solitary upper extremity artery injury repairs and to optimize parameters for optimal clinical out-come.Methods:From March to September 2013,19 injured arteries from 18 male patients who presen-ted at Department of Hand Surgery,Beijing Jishuitan Hospital with traumatic arterial lacerations of their upper extremities went through rapid repair procedures.COUPLER,a microvascular anastomotic coupling device was applied in these artery injury repair operations.The 19 repaired arteries included 3 brachial arteries,6 ulnar arteries and 10 radial arteries.After the procedures,all the 18 patients were then fol-lowed up by clinical specialists and examined with color doppler flow imaging for the effective recovery of artery circulation and upper extremities functionality.Results:The average time of artery repairs for all the 19 damaged arteries among the 18 patients was 278 s and the average follow-up time was (71.5 ± 40.9)d with the longest follow-up time as 116 d and shortest as 14 d.No patient returned to the opera-ting room after the procedures and after being dismissed from the hospital.None of the 18 cases were re-ported to have problems with circulation and thrombosis formation in their upper extremities.Color Doppler imaging showed that the arterial anastomotic site for all the 19 repaired arteries were unobstructed with artery blood spectrum at both ends.Three patients with radial artery repairs complained about mild pressure pain at the site of vascular anastomosis;while the other 15 patients all expressed satisfactory outcomes of the surgery and recovery.These evidences indicated that the outcomes of our initial evalua-tion for the solitary upper extremity artery injury repairs by using anastomotic coupling devices were posi-tive.Conclusion:Our observations have showed that microvascular anastomotic coupling devices can be used for repairing of solitary upper extremity artery injures.The procedures are quick,effective and safe. The clinical application of this microvascular anastomotic coupling device in artery injures is promising, however,additional evidences through further clinical investigation with more cases are warranted.

ObjectiveTo investigate the effect of intensive rehabilitation training on gross motor function in children with cerebral palsy. Methods101 children with cerebral palsy were divided into routine group (n=51) and trunk group (n=50). They were assessed with Gross Motor Function Measure (GMFM) before and after treatment. ResultsThe scores of GMFM improved in both group after treatment. There was significant difference between them 6 months after treatment (P<0.05), but not within 3 months (P＞0.05). ConclusionIntensive rehabilitation training can improve the recovery of gross motor function in children with cerebral palsy.

Objective To investigate the anticoagulant factors that Kazakh women are prone to develop deep vein thrombosis before or after delivery.MethodsThe protein C,protein S,antithrombin Ⅲ (AT-Ⅲ) activity,activated protein C resistance ratio (APCR) of 36 Kazakh women cases and 39 Hans women cases before and after delivery were determined.ResultsThe protein S (43.13±11.36,58.05±17.10) was significant changed (P＜0.01)in Kazakh women before and after delivery.The protein C (97.34±18.37,118.02±23.46) and protein S (58.05±17.10,67.97±19.22) were statistically different between Kazakh women and Han women after delivery(P＜0.05,which protein C was P＜0.01).The anticoagulant indexes of Kazak women after delivery was still within normal range.ConclusionsNormal women have prothrombotic state before and after delivery,especially the Kazakh women.It may be an important factor of deep vein thrombosis-prone before and after delivery that protein C and protein S in Kazakh women have lower activity than that in Han women.The detection of anti-coagulation have some clinical significance on the prevention of the deep vein thrombosis in Kazakh women before and after delivery.

Objective To investigate the relationship of the changes of bone density and biochemical marker of bone turnover with osteoporosis in the elderly with type 2 diabetes mellitus(T2DM). Methods A total of 102 elderly patients with type 2 diabetes and 42 healthy subjects (normal controls) were included in this study.The bone mineral density (BMD) of lumbar vertebrae and femur were measured by dual-energy X-ray absorptiometry (DXA).The T2 DM subjects were divided into two groups:osteoporosis group (56 cases) and non-osteoporosis group (46 cases).The levels of total procollagen type Ⅰ amino-terminal propeptide (TP Ⅰ NP),β-isomerized carboxyterminal propeptide (β-CTx),parathyroid hormone (PTH),serum calcium (Ca2+),serum phosphorus (P),alkaline phosphatase (ALP),fasting blood glucose(FBG),glycosylated hemoglobin (HbAlc) and body mass index (BMI) were detected. The correlations between BMD of the osteoporosis group and other related factors were analyzed. Results The BMD values of lumbar vertebrae and femur neck,troch,ward's triangle in the osteoporosis group were decreased as compared with control(t=9.006,6.347,7.387,5.321,P＜ 0.01) and the serum TP Ⅰ NP,β-CTx,PTH,ALP,FBG,HbAlc,Creatinine and albumin/Cr in the osteoporosis group were significantly higher than controls(t=2.212,4.431,2.215,3.544,0.433,1.629,0.365,5.436,P＜0.01 or P＜0.05),the 25-(OH)VD3 in the osteoporosis group was lower than in controls(t=2.700,P＜0.01).Correlation analysis showed TP Ⅰ NP was negatively correlated with the BMD of femoral Troch and Ward's triangle (r=-0.413,-0.375,P＜0.01),and β CTx was negatively correlated with the BMD of femoral Troch (r=-0.301,P＜0.05).The TP Ⅰ NP,β-CTx in the overweight group and obesity group were higher than in normal group(F=50.59,51.28; F =96.20,95.71,all P＜0.01);the melbine group had higher TP Ⅰ NP,β-CTx than the thiazolidinedione and sulfonylurea group(F=32.33,33.35,F=31.07,39.18,P＜0.01);the TP Ⅰ NP,β-CTx in the better blood glucose control group were lower than in the bad control group(F=11.32,13.69,P＜0.01);the TP Ⅰ NP,β-CTx in the group with complication were increased as compared with no complication group(F=52.75,70.34,P＜0.01).Conclusions The spine BMD in elderly T2DM patients is decreased to some degree.The combined application of TP Ⅰ NP and β-CTx is helpful for the early diagnosis of osteoporosis in patients with type 2 diabetes.

Objective To analyze the economic effects of different rehabilitation patterns for children suffering from cerebral palsy. Methods A total of 153 cerebral palsy patients were divided into a hospital-community-family rehabilitation group(n = 52), a hospital rehabilitation group (n = 50) and a non-intervention control group (n = 51). Those in the first group were provided with a hospital-community-family rehabilitation therapy pattern, those in the sec-ond only hospital rehabilitation and the third no intervention. All the patients were evaluated using the Gross Motor Function Measure-88 (GMFM-88) Scale and the Cost Measure Scale at admission, and at the end of the 3rd and 6th months of treatment. Results There were no significant differences in gross motor function among the three groups at admission. At the end of the 3rd month and the 6th month there were significant differences between the children in the hospital-community-family rehabilitation program and those in the hospital rehabilitation program in terms of gross motor function. Their general percentage, monthly percentage and monthly relative percentage results were all significantly different. But there was no significant difference in the non-interventian control group since admission. Every unit of improvement in gross motor function cost $101.87±97.59, $75.11±45.75 in the hospital-community-family reha-bilitation program and $387.21±54.76, $170.31±123.16 in the hospital rehabilitation program at the end of the 3rd and the 6th month respectively. So the cost of the former was only about 30% of the latter. Conclusion Hospital rehabilitation is suitable for the early rehabilitation of cerebral palsy children. Hospital-community-family rehabilitation is better for long-term rehabilitation of cerebral palsy children, and what is more, it can decrease the rehabilitation ther-apy cost substantially. So a hospital-community-family rehabilitation pattern is more compatible with China's national situation.
