OBJECTIVE:To compare the efficacy and safety of alfacalcidol and strontium ranelate in the treatment of senile menopausal osteoporosis. METHODS:158 elderly menopausal patients with osteoporosis were randomly divided into control group (79 cases)and observation group(79 cases). All patients were orally given 1 Calcium carbonate D3 tablet,once a day. Based on it, control group was given 2 Alfacalcidol soft capsules,once a day. Observation group was additionally given 1 bag of Strontium ranelate dry suspension,orally before bedtime,once a day. The treatment course for both groups was 12 months. L2-4 and BMD of femoral neck,osteocalcin,TPINP and VAS and ADR before and after 6 and 12 months in 2 groups were observed. RESULTS:Before treatment,there were significant differences in the BMD of L2-4 and femoral neck,osteocalcin,TPINP and VAS scores be-tween 2 groups(P>0.05). BMD of L2-4 and femoral neck in control group after 12 months and in observation group after 6 and 12 months were significantly higher than before,and it gradually increased be time in observation,observation group was higher than control group;TPINP and VAS scores in control group after 12 months and in observation group after 6 and 12 months were significantly lower than before,and it gradually decreased be time,observation group was lower than control group,the differenc-es were statistically significant(P<0.05);osteocalcin levels in 2 groups were significantly higher than before,and it gradually in-creased be time,the difference was statistically significant (P<0.05),but there was no significant difference between 2 groups (P>0.05). There were no ADR during treatment. CONCLUSIONS:Based on the conventional treatment,the efficacy of alfacal-cidol and strontium ranelate is superior to alfacalcidol alone in the treatment of senile menopausal osteoporosis,with similar safety.

Objective To investigate the risk factors related with the recurrence of multifocal papillary thyroid microcarcinoma(PTMC).Methods The data of 126 patients undergoing surgery from Jan.2001 to Jun.2011 proved to be multifocal PTMC by pathology were rctrospcctively analyzed.Logistic multifactor regression analysis was used to analyze the clinicopathological factors that may influence the recurrence of PTMC.Results The median age of the 126 patients was 46 years(ranging from 15 to 78 years old).The recurrence rate was 14.3％ (18/126) and the overall survival rate was 98.4％ with the medium follow-up of 75 months (ranging from 24 to 150 months).Multivariate analysis showed that extra-thyoidal extension,neck lymph node metastasis and non-total(or near total)thyroidectomy were the independent risk factors for the recurrence of multifocal PTMC (P =0.008,0.027,0.022 respectively).Conclusions Extension beyond the thyroid and metastatic neck lymph node predict a high risk of recurrence.Total or near total thyroidectomy can reduce the risk of recurrence.

OBJECTIVE: To explore the effect of traditional Chinese herbal medicine (TCM) for nourishing liver and kidney, clearing meridians and removing toxic substances, on the neurobehavioral manifestations and the activity of the dopamine D2 receptor in rat with levodopa-induced dyskinesias (LID). METHODS: The rat model of Parkinson's disease (PD) was established by injecting 6-hydroxydopamine (6-OHDA) into right substantia nigra of brain, then, the model of LID in rat was produced by injecting levodopa (LD) and benserazide for 4 weeks. The rats were divided into normal control group, 4-week LD treated group, 4-week LD plus TCM treated group, 8-week LD treated group, and 8-week LD plus TCM treated group, and the effect of the TCM on neurobehavioral manifestations was observed. The radioligand binding assay (RLBA) and Scatchard drawing were used to measure the maximal binding capacity of receptor (Bmax) and equilibrium dissociation constant (KD) of the dopamine D2 receptor in corpora striatum. RESULTS: Compared with the 4-week LD treated group and 8-week LD treated group, TCM could decrease abnormal involuntary movement scores of the rats with LID; the RLBA revealed that the dopamine D2 receptor Bmax significantly increased (P<0.05, P<0.01) and the KD significantly decreased (P<0.05). CONCLUSION: TCM can improve the activity of the dopamine D2 receptor and relieve the symptoms of LID.

Objective To document the MRI features of renal angiomyolipoma (RAML) containing minimal fat and to explore whether the MR features vary depending on the tumor size. Methods The MR findings of 15 cases of pathologically-proved RAML containing minimal fat were reviewed retrospectively from January 2008 to March 2010. All patients underwent MR in a 1.5 T or 3.0 T scanners. The MR features of the lesions were analyzed, with emphasis on the signal intensity and homogeneity on T2WI, in regards to pseudocapsule, lipid component, hemorrhage, cystic degeneration or necrosis, blood vessels, interface with renal parenchyma and enhancement pattern. All lesions were categorized into 2 groups; those with diameter ＞4 cm and those with diameter ≤4 cm. The difference of imaging characteristics between these two groups was analyzed using Fisher exact test. Results All 15 lesions demonstrated hypointensity on T2WI compared to the renal parenchyma. Homogeneous signal intensity on T2WI was seen in 6 lesions (6/15); peritumoral pseudocapsule in 3 lesions (3/15); cystic degeneration or necrosis, hemorrhage in 5 lesions (5/15); flow void of blood vessels in 2 lesions (2/15); lipid component in 4 lesions (4/15); angular interface with renal parenchyma in 10 lesions (10/15); homogeneous enhancement in 8 lesions (8/15). Fifteen lesions were divided into two groups; 9 categorized into group 1 (the maximum diameter ≤ 4 cm) and 6 into group 2 ( the maximum diameter ＞ 4 cm). Cystic degeneration or necrosis was seen in 0 of 9 in group one and 5 of 6 in group two respectively, hemorrhage(0 of 9 and 5 of 6 respectively) and pseudocapsule(0 of 9 and 3 of 6 respectively. The difference between these findings in the two groups demonstrated statistical significance (P ＜ 0. 05). Conclusion The MR features of RAML containing miminal fat were hypointensity on T2 WI,angular interface with renal parenchyma and homogeneous contrast enhancement, however, these findings can vary depending on the tumor size.

As a common disease in clinical, the treatment of lumbar disc herniation (LDH) focused on local intervertebral disc, such as surgery and other interventional therapy treatment, but postoperative complications and recurrence rate has been a difficult problem in the field of profession. With the development of spine biomechanics and anatomy, researches on lumbar herniation also increased. Researchers discovered that the incidence and prognosis of LDH were inseparable with local muscle and soft tissue. As the deep paraspinal muscles, multifidus muscle plays an important role to make lumbar stability. Its abnormal function could reduce the stable of lumbar spine, and the chronic lumbar disease could also lead to multifidus muscle atrophy.

Objective To evaluate the necessity of concomitant bladder cuff and the possibility of distal ureter sparing surgery during radical nephroureterectomy of low-level upper urinary tract tumors. Methods Clinical data of 73 patients with low-level (Tis-T3 M0 N0 ) tumors of the proximal upper urinary transitional epithelial cancer treated in radical nephroureterectomy in our hospital from 2000 to 2007 were analyzed retrospectively. The medical charts and pathologic specimens of 35 patients with, and 38 patients without, concomitant bladder cuff were reviewed. Results In the 35 patients with concomitant bladder cuff resection, 8 cases (22.9%) recurrence was observed; in the 38 patients without concomitant bladder cuff resection, 8 cases (21.1%) recurrence was observed. There was no difference between both groups(P>0.05). In the 19 patients suffered renal pelvis tumors with concomitant bladder cuff resection, 4 cases (21.1%) recurrence was observed; In the 16 patients suffered ureter tumors with concomitant bladder cuff resection, 4 cases (25 %) recurrence was observed.There is no difference between patients of renal pelvis tumors and of ureter tumors with concomitant bladder cuff(P>0.05). In the 27 patients suffered renal pelvis tumors without concomitant bladder cuff resection, 3 cases (11.1 %) recurrence was observed; in the 11 patients suffered ureter tumors with concomitant bladder cuff, 5 cases (45.5%) recurrence was observed. There was significant different between patients of renal pelvis tumors and of ureter tumors without concomitant bladder cuff (P<0. 05). Conclusion Concomitant bladder cuff resection confers a favorable prognosis to the patients with ureter tumors, but not to the patients with renal pelvis tumors.

Objective To understand how about the female consumers know the skin conditions of themselves and which they concern by a comprehensive questionnaire. Methods Three hundred and twenty-eight healthy volunteers in Shanghai were involved in this study. They were divided into 5 age groups equally. The questionnaire included the skin conditions, i.e. skin moisture, sebum, whiteness, redness, xanthochromia, homogeneity, spots, fine line, wrinkle, elasticity, angiotelectasis,pore, sagging, smoothness, gloss, roughness, scales and sensitivity. Each condition was divided into 10 grades to assess the skin conditions of the face (exposed site), upper arm (non-exposed site) and the perfect skin status. SPSS11.5 software was used to analyze the correlations of the skin conditions with ages. Results The skin concerns were difference in the 5 groups. Skin aging of sagging, wrinkle, spots and fine line became prominent from group C (35 to 40 years old). The correlations between the skin concerns of facial moisture, sebum, whiteness, homogeneity, spots, wrinkle, fine line, elasticity, sagging, sensitivity, upper arm sebum, spots, elasticity, angiotelectasis, sagging and roughness with ages were very significant (P＜0.01). Conclusion The changes of the volunteers'concerns about sebum, pore, sagging, elasticity, fine line and wrinkle with age in different age group are consistent with the quantitative measurement results from the oversea studies.

Objective To investigate the infection of Xuebijing injection on inflammatory factor of large sized avulsion patients.Methods 70 patients being selected with large sized avulsion were randomly recruited into a treatment group(35 patients)and a control group(35 patients).The control group received traditional comprehensive treatment.On this basis,Xucbijing injection was injected to the treatment group on admission day,and Xuebijing injection 50 ml in 0.9%NaCl solution 100 ml was,intravenously infused for 60 min once,2 times daily,up to 7 d.TNF-α,IL-6,CRP,WBC and NEU%of the two groups were respectively detected before treatment and 7 days after the treatment.Exudation of wound surface was also observed.Results After 7 days of treatment,there was significant difierence in the treatment group compared with pretreatment(P＜0.01).There was statistical difference between two groups after 7 days of treatment(P＜0.01).Exudation of wound surface of the treatment group was less than the control group's.Conclusion Xuebijing injection has antagonistic effect on inflammatory factor of large sized avulsion patients and can lessen exudation of wound surface.

Objective To establish the method of testing immunoglobulin G (IgG) with Fc sialylation, and to investigate the clinical significance of IgG with Fc sialylation in systemic lupus erythematosus (SLE), especially in those with neuropsychiatric manifestations (NPSLE). Methods Seventy-five SLE including thirty patients with neuropsychiatric manifestations (NPSLE) and forty-five non-NPSLE patients, 30 rheuma-toid arthritis (RA) patients, 32 juvenile idiopathic arthritis (JIA) patients and 41 healthy controls were recruited in this study. Standard method of testing lgG with Fc sialylation was established by a lectin based sandwiched enzyme linked immunosorbent assay (ELISA). The levels of IgG with Fc sailylation were assayed, and its clinical significance was evaluated. Results There were no difference in the levels of serum IgG with Fc sailylation in RA group (0.82±1.81) mg/ml, JIA group (0.69±1.30) mg/ml, healthy control group (0.64± 1.09) mg/ml, and the levels of IgG with Fc sailylation in SLE group (0.12±0.17) mg/ml (P<0.01), especially in NPSLE group [(0.03±0.03) mg/ml, P<0.01] was significantly lower than that of control groups. The perc-entage of IgG with Fc sialylation in control group (4.64±5.90)% were significantly higher than that in non-NPSLE (1.88±2.16)% (P<0.01) and in NPSLE (0.29±0.47)% (P<0.01). The percentage of IgG with Fc sial-ylation was negatively associated with SLEDAI score (r=-0.43, P<0.01). Conclusion Significantly low level of serum IgG with Fc sialylation was associated with disease activity in SLE patients, especially in NPSLE patients, lgG with Fc sialylation may be a new target for therapeutic strategy.

Objective To establish a swine model of 10 min prolonged cardiac arrest (CA) induced by electrically triggered ventricular fibrillation,and then evaluate the quality of the model and the value in the establishment of post-cardiac arrest syndrome.Methods Fourteen domestic healthy swine weighing 38 ±3 kg were selected for study.Ventricular fibrillation was induced for 10 min,and then cardiopulmonary resuscitation (CPR) was initiated and continued for 5 min.The resuscitated animals were observed for 72 h after resuscitation.The resuscitation outcomes and survival rate were recorded.The functions of heart,lung and brain,and systemic inflammatory response and tissue perfusion were regularly evaluated for 72 h post-resuscitation.Results Eleven of the fourteen swine obtained restoration of spontaneous circulation (ROSC),and the rate of successful resuscitation and 72 h survival were both 78.6％.Significantly worse post-resuscitation myocardial function was found in all animals compared to the value prior to CA and the myocardial function was evaluated by decreased stroke volume and global ejection fraction,and increased levels of serum cardiac troponin-Ⅰ and n-terminal pro brain natriuretic peptide.Postresuscitation extra-vascular lung water index and pulmonary vascular permeability index were significantly increased accompanied with significantly decreased oxygenation index compared with the values before CA,indicating the occurrence of acute lung injury.In addition,post-resuscitation systemic inflammatory response and tissue low perfusion evidenced by significantly higher levels of serum tumor necrosis factor-α and interleukin-6 and arterial blood lactate were observed.Consequently,severe neurological deficit with significantly higher levels of serum neuron-specific enolase and S-100B was observed following 72 h postresuscitation.Conclusions This swine model of prolonged cardiac arrest induced by electrically triggered ventricular fibrillation was a well established model with high success rate of resuscitation,significant vital organ injury and relatively long duration of survival;it is an excellent model for the study of post-cardiac arrest syndrome.
