Objective To analyze X-ray findings of diaphragm and other related features in the diagnosis of hyperthyroid cardiopathy.Methods Forty cases without any other disease were taken chest plain film before therapy.The X-ray findings were analyzed.Results In all of X-ray features,low and flat diaphragm;barrel chest;increased and wide lung marking,which presented as network-like structure with mottling in bilateral inferior lung were closelv related to pathologic changes.Pneumonemia;pulmonary stasis;prominence of pulmonary artery segment;dilatation of right inferior pulmonary artery were related to othe change of heart and pulmonary circulation.Conclusion X-ray findings are closely related to the severe degree of pathologic changes in hyperthyroid cardiopathy.It is valuable for clinical diagnosis and treatment to recongnize these X-ray findings accurately.

Objective To observe the influence of short-term continuous subcutaneous insulin infusion(CSII)on ?-cell function in newly diagnosed type 2 diabetes(T2DM).Methods A total of 32 inpatients with newly diagnosed T2DM who had a 14-day course of CSII were randomly assigned to two groups of OGTT and arginine stimulating test(AST).Before and after 3 days and 14 days CSII treatments,OGTT and AST were performed respectively.The changes of the values of plasma glucose,HOMA-IR,HOMA-? and △C30/△G30,△C120/△G120 or arginine-induced acute C-peptide reaction(ACRARG)in two groups were compared.Results In OGTT,the values of plasma glucose and HOMA-IR were decreased,HOMA-? and △C120/△G120 were increased significantly after CSII therapy,both in day 3 and day 14;and △C30/△G30 were unchanged after 3 days but increased markedly after 14 days.However,in ACRARG,the above mentioned parameters almost remained unchanged after CSII treatment in 3 days or 14 days.Conclusions In newly diagnosed T2DM with elevated fasting glucose levels,intensive insulin therapy can partly improve ?-cell function showed by OGTT,not by AST.

Objective To evaluate the feasibility, toxicity and clinical efficacy of simultaneous modulated accelerated radiation therapy(SMART)for nasopharyngeal carcinoma. Methods Thirty eight patients with nasopharyngeal carcinoma were treated by SMART with 2.5?Gy/fraction at gross tumor volume(GTV)to a total dose of 70?Gy and 2.0?Gy/fraction at the clinical treatment volume(CTV)to a total dose of 56?Gy in 38 days. Quantitative 99m Tc pertechnetate salivary scintigraphy was used to assess the uptake and excretion index (EI、UI) of parotid gland in order to validate the value of IMRT in parotid gland sparing. Results The mean doses delivered to the GTV and CTV were 67.2?Gy and 57.0?Gy, respectively. An average of 1% of GTV and 2% of CTV received less than 90% or 95% of the prescribed dose. The mean dose to the contralateral parotid were 23?Gy and no significant decline in EI and UI as compared with significant decline in the ipsilateral parotid by 43.6% and 26.3%(P

OBJECTIVETo observe the effects of Xiaobai Decoction (XBD) in reducing albuminuria and shortening the duration of albuminuria in patients with pregnancy-induced hypertension syndrome (PIH) in puerperium.

METHODSEighty-five patients were given the conventional treatment with magnesium sulfate for relieving convulsion and lowering hypertension, at the same time, the treated group was given XBD additionally with the modification according to the symptoms. The treatment course for both groups was 14 days. Routine test of midstream urine was performed every three days, and 24 h-urinary protein was measured every week.

RESULTSThe therapeutic effect on the 43 patients of the treated group was markedly effective in 11 (25.6 % ), effective in 26 (60.4%) and ineffective in 6 cases (14.0%), the total effective rate being 86.0%; while in the 42 patients of the control group, the corresponding numbers were 5 (11.9%), 21 (50.0%), 16 (38.1%) and 61.9%, respectively, the efficacy of the former was significantly better (P < 0.05).

CONCLUSIONXBD is a simple, safe and effective drug for reducing albuminuria and shortening the duration of albuminuria in puerperium of PIH patients.

Objective To analyze the histological changes of bone diseases and to investigate the noninvasive measurements for diagnosing renal osteodystrophy (ROD) in maintenance dialysis patients . Methods Ninety-one patients were selected to receive bone biopsy . The bone samples were stained with HE, toluidine blue and Masson, and were examined with light microscopy . The levels of immunoreactive parathyroid hormone (iPTH), osteoprotegerin (OPG),sRANKL and osteocalcin (OCN) were determined in the patients enrolled from 2004 to 2006 . The level of iPTH was measured by radioimmunoassay . OPG and sRANKL were measured by ELISA,and OCN was measured by chemiluminescence . Results The incidence of ROD in the maintenance patients was 100% . According to the histological appearance, 50 cases (54 .9%) were high turnover bone disease (secondary hyperparathyroid bone disease), 9 cases (9 .9%) were low turnover bone diseases(osteomalacia and adynamic bone disease), and 32 cases(35 .2% ) were mixed bone disease . The level of iPTH in patients with ROD was significantly increased compared with healthy controls . It was the lowest in low turnover bone diseases . There was no difference among three types of ROD . OPG level was significantly increased compared with healthy controls [(2176 .58±1576 .08) pmol/L vs (1310 .46±1254 .00) pmol/L, P＜0 .05] . The level in high turnover bone diseases was higher than that of the healthy controls [(2261 .85±1712 .22) pmol/L vs (1310 .46±1254 .00) pmol/L, P＜0 .05] . There was no difference among three types of ROD .sRANKL level in high turnover bone disease was significantly increased compared with healthy controls [(0 .328±0 .524)pmol/L vs (0 .084±0 .190) pmol/L, P＜0 .05] . OCN level was also higher than that of the healthy controls (P＜0 .05), and the OCN level in low turnover ROD was the lowest among three types of ROD . OCN level in mixed ROD was dramatically increased as compared to low turnover ROD [(226 .633±66 .455) pmol/L vs (193 .03±104 .269) pmol/L, P ＜0 .05] .Conclusions The histological changes of bone disease can be indicated by iPTH level, but the types of ROD can not be distinguished according to iPTH level neither be differentiated by the levels of OPG, sRANKL and OCN . Bone histomorphometry is still the golden standard for diagnosing renal osteodystrophy .

Objective To find out the cognition understanding of iodine deficiency disorders(IDD) of target population in Xi’an City, and evaluate the effectiveness of a health education project on prevention and control of IDD. Methods By using the random number table, three towns in each project county were selected. Obeying the requirements of the education program for IDD control, the health education activities were implemented during 2007 - 2011. Before and after intervention, questionnaire was used to investigate the intervention effect. The primary school grade 5 students and women of childbearing age were included in the survey of IDD knowledge. Hierarchical random sampling method was used to select pupils and childbearing women. Results After health education, the rate of knowledge on IDD increased from 66.97%(13 321/19 890) to 93.49%(18 610/19 905,χ2 = 4 413.07, P < 0.05) among pupils, and 62.27%(6 193/9 945) to 93.96%(9 361/ 9 963, χ2= 2 924.18, P<0.05) among childbearing women. And the awareness had reached the national standard. But the survey results showed that: the rate of IDD related knowledge in rural areas was lower than that in town areas. The awareness rates of IDD in precaution, main hazards, identification of iodized salt were 46.50%(239/514), 55.25%(284/514) and 50.97%(262/514) among pupils in rural areas and 61.44%(376/612), 65.69%(402/612) and 70.59%(432/612) among pupils in town areas, and the awareness rates of pupils in rural areas were lower than those of pupils in town areas. Thirty-six point ninety-three per cent(226/612) of the pupils in towns and 35.60%(183/514) of the pupils in rural areas told this information to their parents. The awareness rates of IDD in precaution, main hazards, IDD prevention day were 49.25%(197/400), 50.75%(203/400) and 36.50%(146/400) among women in rural areas and 75.44%(298/395), 80.25%(317/395) and 57.97%(229/395) among women in town areas, and the rates of women in rural areas were lower than those of women in town areas. The rate of consciously purchasing of qualified iodized salt was 51.75%(207/400) and the consumption rate of iodized salt was 36.75%(147/400) among women in rural areas, which were 73.42%(290/395) and 43.80%(173/395) among women in town areas, and the rates in rural areas were lower than those in town areas. Conclusions Before health education of IDD, the rate of IDD related knowledge in Xi’an City is poor, rural areas are lower than town areas. Health education project is effective in promoting the understanding and grasp of IDD knowledge.

AIM: To study the molecular mechanism in modulation of expression of insulin receptor substrate-1 and-2 (IRS-1,-2) by estrogen and high concentration of insulin. METHODS: The 5′-regulatory regions of IRS-1 and IRS-2 gene were cloned into the pGL3 plasmid with luciferase reporter, and the clones were transfected into HeLa cells. The cells were incubated with estradiol (1 nmol/L) and high concentration of insulin (100 nmol/L). The relatively transcriptional activity of the 5′-regulatory regions of IRS-1 and IRS-2 gene was detected. RESULTS: It was found that the relatively transcriptional activity of the 5′-modulatory regions of IRS-2 reduced markedly after cells were incubated with 100 nmol/L insulin (P

AIM:To investigate the influence of ovariectomy and estrogen replacemeot treatment on profile of gene expression in myocardium by cDNA microarray,and to characterize the targeting genes of estrogen.METHODS:cDNA microarray containing 1 400 rat cDNAs was used to study the genes differentially expressed in myocardium between sham(Ⅰ),ovariectomy(Ⅱ,OVX)and estrogen replacement treatment(Ⅲ,OVX+E2)group.Then down-regulated genes in myocardium of OVX rats were further confirmed by RT-PCR.RESULTS:177 genes were differentially expressed in myocardium between sham and OVX rats,with 91 genes up-regulated and 86 genes down-regulated in OVX rats.164 genes were differentially expressed in myocardium between OVX and OVX+E2 rats,with 113 genes up-regulated and 54 genes down-regulated in OVX rats.There were 54 genes differentially expressed in OVX compared to sham and OVX+E2.They are involved in membrane channels and transporters(18),cell receptors(9),intracellular transducers/effectors/modulator(7)and metabolism(6).Most of the genes(45)were down-regulated in OVX rats and up-regulated in OVX+E2 rats.RT-PCR test confirmed the results of cDNA microarray.CONCLUSIONS:Long-term estrogen replacement may influence the expression of genes involved in membrane channels and transporters,cell receptors,intracellular transducers/effectors/modulator and metabolism.Long-term estrogen replacement has some beneficial effects on ionic concentration and cardiac function which partially comes from the results of influence of expression on Na+,K+-ATPase and Na+/H+ exchanger.Estrogen has an inhibitory effect on the expression of dopamine receptor,which partially clarify the myocardial protection of estrogen.

Objective: To observe the clinical efficacy of spleen-invigorating and qi-benefiting pediatric massage (tuina) for treating recurrent respiratory tract infection in children with cerebral palsy due to qi deficiency of spleen and lung. Methods: A total of 70 children with cerebral palsy who suffered from recurrent respiratory tract infection due to qi deficiency of spleen and lung were randomized into an observation group and a control group by the random number table method, with 35 cases in each group. Both groups were treated with conventional rehabilitation training, while the observation group was given additional spleen-invigorating and qi-benefiting pediatric massage, and the control group additionally took oral Yu Ping Feng granule. The clinical efficacy was evaluated by the total effective rate, traditional Chinese medicine (TCM) symptom score, and serum levels of immunoglobulin (Ig) A, IgM and IgG. Results: The difference in total effective rate between the two groups after treatment was statistically significant (P<0.05). After treatment, the TCM symptom scores in both groups decreased to varying degrees than those before treatment, and the intra-group differences were statistically significant (all P<0.01); the differences in the scores of various TCM symptoms between the two groups were statistically significant (all P<0.05). After treatment, the levels of IgA, IgM and IgG of the children in both groups increased to varying degrees, and the intra-group differences were statistically significant (all P<0.05). The between-group differences in the IgA, IgM and IgG levels after treatment were statistically significant (all P<0.05). Conclusion: Spleen-invigorating and qi-benefiting pediatric massage can effectively treat recurrent respiratory tract infection due to qi deficiency of spleen and lung in children with cerebral palsy, relieve the clinical symptoms and improve immune function, and thus is worthy of clinical promotion and application.
