Osteoporotic fracture is the most destructive ending of osteoporosis, many interacting risk factors play a role in its occurrence. With age, the bodies function decline gradually. Symptoms like soreness of the waist, back pain, cramp of the lower limb and weakness appears. These are related to TCM syndrome factors like kidney deficiency, liver deficiency, spleen deficiency and blood stagnation. Symptoms can act as a warning of the occurrence of osteoporotic fracture in the early stages. The risk assessment tool of osteoporotic fracture is mostly developed on the basis of modern risk factors and thus lacks syndrome differentiation, that may limit its utilization. If the relevant content of syndrome differentiation is integrated into the forecasting tool and a risk assessment tool of osteoporotic fracture which complies with the demographics of China is built up, population risk assessment for high of risk could be established and scientific evidence for the adoption of effective interventions could be applied.

To investigate the clinical efficacy of distally based myocutaneous flap pedicled with nutrient vessel of cutaneous nerve of leg for the treatment of traumatic chronic osteomyelitis of lower leg. A total of 25 patients with traumatic chronic osteomyelitis of lower legs were from Department of Burn and Plastic Surgery, Beijing Jishuitan Hospital from January 2002 to June 2008. All the patients were treated with distally based myocutaneous flap pedicled with nutrient vessel of cutaneous nerve of leg after thoroughly debridement. Among them, 6 patients were treated with myocutaneous flap with nutrient vessel of saphenous nerve, and 19 patients were treated with myocutaneous flap with nutrient vessel of sural nerve. The sizes of the flaps were 5 cm×3 cm-18 cm× 12 cm, with attached muscles were 3 cm×3 cm-8 cm×5 cm. The lengths of the pedicles were 5-12 cm. All transplanted myocutaneous flaps survived well. A 6-24 months follow-up of all patients was obtained. The shape and texture of the myocutaneous flaps were good. And there was no recurrence of osteomyelitis. Results suggested that the distally based myocutaneous flap pedicled with nutrient vessel of cutaneous nerve of leg had reliable blood supply and satisfied efficacy, which was a good method for repairing traumatic chronic osteomyelitis of lower leg.

Objective To investigate the expression of NF-k B and c-myc in keratinocytes of HPV infected condyloma acuminata (CA) lesions.Methods Fifty cases of HPV 6/11 positive CA were diagnosed by in situ hybridization.The expression and distribution of NF-k B and c-myc were detected by immunohistochemistry technique (EnVision) with CA lesions and 25 normal human skins (foreskins). Results②The expression of NF-k B and c-myc was significantly higher in keratinocytes of CA lesions than those of normal controls (P＜0.01 ).NF-k B was mainly expressed in spinous layers of CA lesions, and most positive signals located significantly in the cytoplasm.C-myc was mainly expressed in the whole epidermis or in spinous and basal layers in CA lesions,and positive signals located in the nuclei.②There was a positive correlation between the expression of NF-k B and c-myc in CA lesions (r=0.89,P＜0.01).Conclusions The study demonstrates that the expression of both NF-k B and c-myc is significant- ly higher in HPV 6/11 positive CA than in normal skin.The data suggest that transcriptional factor NF-k B and c-myc may play a role in the regulation of proliferation of HPV 6/11 infected cells.

Objective To search a new,safe and effective method to obtain semen using rectal Drobe electroejaculation(RPE).Methods RPE procedures were performed in 8 men with psychological ejaculatory failure,used the electrical stimulate instrument(CGS model,made in Italy).The average age was 26 years.Seminal vesicle was normal by B Uhrasonography or CT examination.Except for 1 case of diabetes,the other 7 cases found no hormones,blood,biochemical and nervous system abnormalities.Three cases had nocturnal emission,but no sexual intercourse ejaculation.Results Adequate sperm was successfully taken out from the 8 patients.Mean seminal fluid volume was 2.3 ml,mean total sperm count was 67×106/ml and mean total motile sperm was 21.3%.Three patients felt abdominal distension during the RPE course.Conclusion RPE is a safe,reliable,non-in-vasive,repeatable method to obtain semen.

OBJECTIVETo observe the result of repairing deformity due to cicatricial contracture in face and neck regions with expanded skin flap.

METHODSEighty-three skin expanders with volume ranging from 100 to 600 mL were implanted into 38 patients with scars in face and neck regions after burn. The expansion time ranged from 3 to 5 months. Most expanders were implanted under normal skin. Ten expanders were implanted under stable integrated scars after healing of burn, and flaps therefrom were transplanted; 3 expanders were implanted into deep fascia layer of trapezius, and remote expanded skin flaps with deep branch of transverse cervical artery as the pedicle were formed and transplanted.

RESULTSAll flaps survived in 38 cases with satisfactory results. Complications including hematoma and infection after surgery occurred in 8 cases, but they did not affect therapeutic effect after treatment. Thirty patients were followed up for 3 to 24 months. It was found that the color and texture of skin flaps were good; appearance and function were obviously improved.

CONCLUSIONSExpanded skin flap is the best flap for repairing cicatricial deformity in face and neck regions after burn. Expanded cicatricial skin and expanded skin of remote region are good choices when normal skin is not available nearby.

BACKGROUND:The study aimed to compare the therapeutic effect of recombinant tissue plasminogen activator (rt-PA) on the onset of acute cerebral infarction (ACI) at different time points of the first 6 hours.METHODS:A retrospective analysis was conducted in 74 patients who received rt-PA thrombolysis treatment within 4.5 hours after ACI and another 15 patients who received rt-PA thrombolysis treatment between 4.5-6 hours after ACI.RESULTS:National Institute of Health Stroke Scale (NIHSS) scores were statistically decreased in both groups (P>0.05) at 24 hours and 7 days after ACI. There was no significant difference in modified ranking scores and mortality at 90 days after the treatment between the two groups (P>0.05).CONCLUSIONS:The therapeutic effect and mortality of rt-PA treatment in patients with ACI between 4.5-6 hours after the onset of the disease were similar to those in patients who received rt-PA within 4.5 hours after the onset of this disease. Therefore, intravenous thrombolytic therapy for ACI within 4.5-6 hours after ACI was effective and safe.

OBJECTIVETo inquire into the relationship between lipoprotein lipase (LPL) gene D9N, N291S and S447X polymorphisms and the development of cardiovascular diseases in children with obesity.

METHODSThe polymerase chain reaction (PCR) and restriction fragment length polymorphism (RLFP) techniques were used to detect three common mutations of LPL gene exon D9N, N291S and S447X in 157 obese children and 175 normal controls. Plasma lipid and lipoprotein levels between children with different genotypes were compared.

RESULTSThe D9N and N291S gene mutations were not detected in either the obese or the control groups. There were no significant differences in the frequency of S447X gene mutation between the two groups. There were no significant differences in the levels of plasma lipid and lipoprotein between children with S447 and X447 genotypes.

CONCLUSIONSD9N and N291S gene mutations may not be risk factors associated with cardiovascular diseases in children with obesity. S447X gene mutation might not play an important role in the development of cardiovascular diseases in childhood.

Any kind of clinical study can supply clinical decision-making with useful information when they are designed and reported properly. However, results with bias or mistake can misguide doctors' decisions, if trials with poor design quality were reported wrongly. Therefore, researchers should report trials accurately and critically, so that the quality of trials could reach a high level and get trustworthy results. This article made an overview of many kinds of reporting standards about systematic reviews and all kinds of trials. We hope these international published standards could be helpful for Chinese medicine researchers in their practice.

OBJECTIVETo compare the safety and efficacy between two different surgical approaches for thoracoscopic esophagectomy including left lateral decubitus position and prone position.

METHODSFrom January 2008 to December 2009, 88 patients who underwent thoracoscopic esophagectomy were enrolled in this study. Among them, 52 patients were placed in decubitus position and 36 patients were placed in prone position.

RESULTSNo conversion to thoracotomy occurred in either group. The operative time was shorter in the prone group than that in the decubitus group (70 ± 20 min vs. 82 ± 17 min, P<0.01). Blood loss during operation was less in the prone group(100 ± 52 ml vs. 139 ± 54 ml, P<0.01). More lymph nodes were harvested from chest in the prone group(12.2 ± 6.2 vs. 8.6 ± 4.3, P<0.01). There was no significant difference between the two groups in morbidity.

CONCLUSIONThoracoscopic esophagectomy in prone position is associated with better exposure of surgical filed, shorter operative time, less blood loss, and more extensive lymph node dissection as compared to decubitus position.
