Objective To investigate disorders in calcium and phosphorus metabolism and abnormity in parathyroid function and their related factors in maintenance hemodialysis(MHD)patients.Methods We collected serum Hb,SCr,BUN,calcium,phosphorus,iPTH,high sensitivity C-reactive protein(hs-CRP),albumin and calculated albumin-corrected Ca and Kt/V from 198 patients with MHD in Jing'an District Central Hospital,Shanghai from Jan.2009 to Dec.2010.The calcium and phosphorus metabolism and parathyroid function were evaluated according to the guidelines of bone metabolism and controlling of bone disease in Kidney Disease Outcome Quality Initiative(KDOQI)recommended by National Kidney Foundation of the United States.198 patients were classified into the standard group(150-300 ng/L),lower than the standard group(＜150 ng/L)and higher than the standard group(＞ 300 ng/L)according to serum iPTH levels.Results In the 198 cases,110 cases were normal in serum Ac-Ca(55.6％); 118 cases were normal in serum phosphorus (59.6％); 143 cases were normal in Ca × P(72.3％); 39 cases were normal in iPTH(19.7％).All four items up to the standard were 28 cases(14.1％)among 198 cases.However,132(66.7％)patients showed lower than 150 ng/L in serum iPTH.The average serum iPTH gradually decreased with age.The senior patients demonstrated the highest average serum Hs-CRP,the lowest average serum phosphorus and the lowest albumin.There were no statistical significance in sex,hemodialysis duration,diabetes,blood pressure,Hb,Bun,SCr,Ac-Ca and Kt/V among three groups.Conclusion The disorders in calcium and phosphorus metabolism and abnormity in parathyroid function is common in the MHD patients.We should pay attention to hypofunction of parathyroid gland in the patients with MHD,which may be related to aging,malnutrition and potential infection.These findings need further investigation.

Objective To study the short-term clinical efficacy and its possible mechanism of refractory hypertension(RH) treated by continuous veno-venous hemofiltration (CVVH) in maintenance hemodialysis (MHD) patients. Methods Thirty-four MHD patients with RH treated with CVVH enrolled in the treatment group,all these patients were treatment of 2 -3 times,each time 8 - 10 hours. Thirty MHD patients with wellcontroled blood pressure were recruited as control. Changes of blood pressure, dry weight, plasma levels of parathyroid hormone (PTH), renin ( RA), angiotensin Ⅰ , Ⅱ ( AT Ⅰ , AT Ⅱ ), aldosterone ( Ald ) were observed before and after hemodialysis. Results In the treatment group,compared with pre-treatment, the blood pressure decreased significantly with an effective rate of 64.7% and efficient rate of 100. 0%. Before treatment, plasma RA was ([1.10 ±0.25] μg/(L · h)and [0:78 ±0.26] μg/(L · h),AT Ⅰ was [0.89 ±0.21] μg/L and [ 0. 52 ± 0. 14 ] μg/L, AT Ⅱ was [ 177.68 ± 89.46 ] ng/L and [ 89. 25 ± 12. 84 ] ng/L, Ald was [72. 06 ± 11.47 ]ng/L and [ 48.92 ± 8. 65 ] ng/L, PTH was [ 306. 81 ± 69. 37 ] ng/L and [ 248.76 ± 134. 62 ] ng/L in the treatment and control group respectively. All the measurements in the treatment group were significantly higher than those in the control group (P ＜ 0. 05 ). In the treatment group, compared to pre-treatment, plasma RA significantly decreased ( [ 1.10 ± 0. 25 ]μg/ ( L · h) vs [ 0. 76 ± 0. 17 ] μg/( L · h ), as well as AT Ⅰ ( [ 0. 89 ±0.21]μg/L vs [0.50 ±0.12] μg/L),ATⅡ([177.68±89.46]ng/L vs [ 87.13±14.22] ng/L),Ald ([72.06±11.47]ng/Lvs [ 46. 01± 9. 86 ] ng/L ) and PTH ( [ 306. 81 ±69.37]ng/L vs [ 186.53 ±32.93 ] ng/L) ( P ＜ 0. 05 ). However, there was no significant changes in the above mentioned measurements between before and after hemodialysis in the control group (P ＞ 0. 05). Conclusion CVVH may be an effective methods in the treatment of MHD patients with RH, and its antihypertensive mechanisms may be that CVVH can effectively remove the excess water in the body, and reduce plasma RA, AT Ⅰ , AT Ⅱ ,Ald and PTH levels.

Objective To observe the curative effect of autologous bone marrow stem cells implantation to bone inducing active material combined with core decompression in the treatment of early femoral head osteonecrosis (FHON).Methods From April,2010 to March,2012,in Department of Orthopaedics,the First Affiliated Hospital of Zhengzhou University,a total of 79 adult patients with 108 hips suffered from the early stage FHON were treated with autologous bone marrow stem cells implantation to bone inducing active material combined with core decompression through the core of the femoral canal,male of 65 cases,female of 14 cases,the mean age was 29.5 (20-50) years old.According to the etiology classification:the alcohol-induced FHON was in 54 patients with 66 hips,steroid-induced FHON in 14 patients with 20 hips,steroid and alcohol-induced ONFH was in 11patients with 22 hips.According to association research circulation osseous (ARCO)classifying,Ⅰ-A,Ⅰ-B,Ⅱ-A,Ⅱ-B phases were 6,16,8,and 78 hips,respectively.There were 43 hips in left side and 65 hips in the right side.Results All patients were followed up from 4 to 6 (4.8 ± 0.6) years.Compared with before operation,the scores of all patients were significantly increased (P ＜ 0.05).All patients with hip pain symptoms were relieved or disappeared.The healing tine of the patients in all age groups was statistically significant (P ＜ 0.05),and with the increase of age,the healing time was prolonged.The excellent and good rates of Ⅰ-A,Ⅰ-B,Ⅱ-Aand Ⅱ-B were 100％ (6 / 6),100％ (16/16),100％ (8/8),and 98.7％ (77/78).The X-ray showed that coarse channel osteogenic phenomenon is obvious,there is 1 case collapse of femoral head of stage Ⅱ-B,the rest were not collapse.Conclusion The treatment of early osteonecrosis of the femoral head with autologous bone marrow stem cells implantation to bone inducing active material combined with core decompressionis definitely effective,especially in patients with ARCO:Ⅰ-A,Ⅰ-B and Ⅱ-A phase,and the effect of ARCO:Ⅰ-A and Ⅱ-A is the best.

To investigate the utility of optomap panoramic 200Tx in screening fundus disease among the patients after cataract surgery.
●METHODS: From November 18 th to December 31st , 2013 all 146 post- cataract surgery patients were recruited. All non - mydriatic fundus images were taken with the optomap panoramic 200Tx and were diagnosed by one masked retinal specialist. Non - mydriatic direct ophthalmoscope exam and mydriatic slit-lamp lens exam were also done by other two masked specialists. Comparisons of the three methods were made.
●RESULTS: Among 146 patients ( 161 eyes), 40 eyes (24. 8%) of retinal lesions was detected by non-mydriatic direct ophthalmoscope exam, 59 ( 36. 7%) by non -mydriatic optomap 200Tx exam, and 61 (37. 9%) by slit-lamp lens exam. Nine eyes ( 5. 6%) needed medical intervention immediately. Results of optomap 200Tx exams and slit - lamp lens exams were similar without statistically significant difference ( P > 0. 05), better than direct ophthalmoscope exam ( P < 0. 05) with statistically significant difference.
● CONCLUSlON: Opacification of the refractive medium makes thorough fundus examination impossible. So post-operative fundus examination is highly necessary and should be a routine. Optomap panoramic 200Tx, which shows no statistically difference from mydriatc slit- lamp lens exam, is a convenient and feasible method in discovering fundus pathological changes.

Objective To investigate the cognitive dificiency characteristics and the neuro electrophysiological mechanism of sleep disordered breathing(SDB) in school-age children.Methods20 cases of SDB children and 20 cases of normal group at 6-8 years old participated in the continue performance test(CPT-AX).The amplitude and latency of N2,P3 of event related potentials(ERPs) were measured and analysed at Fz leads,and the behavioral results were recorded at the same time.ResultsThere were no significant differences between SDB group and normal group in behavioral correct number (36.10±4.69 vs 35.05±3.49),the reaction time ((523.77±68.73)ms vs (496.59±78.65)ms) and false alarm number (1.0 (0.25,3.75) vs 0.5 (0.00,3.00))(all P>0.05).The SDB group showed significant increase in Go-P3 amplitudes compared with the normal group((10.25±6.46)μV vs (6.56±4.63)μV,P<0.05).The Go-P3 latency in SDB group was significantly prolonged than that in the normal group((438.80±59.72)ms vs (406±36.30)ms,P<0.05),and the Nogo-N2 amplitude in SDB group significantly decreased compared with the normal group ((-12.46±4.75)μV vs (-15.50±3.82)μV,P<0.05).ConclusionThe children aged 6 to 8 years old with sleep disordered breathing consume more resources and time to complete the attention process,like a compensatory response.And during the monitoring process there is a resource shortage that results in obvious defect in process of inhibition.

Abstract: Schistosomiasis, an important zoonotic parasitic disease, is one of the six major tropical diseases identified by WHO, and also one of the most important parasitic diseases for prevention and control in China. After more than 70 years of efforts, the prevention and control of schistosomiasis in China has made great achievements, and the current epidemic of schistosomiasis in China has entered an extremely low epidemic state, but the distribution base of the only intermediate host of schistosomiasis, Oncomelania hupensis, is still large. For now, the techniques used to monitor schistosomiasis have shortcomings such as time-consuming, laborious and low sensitivity, which cannot meet the current needs of China. Environmental DNA (eDNA) refers to DNA that can be extracted from environmental samples (such as soil, water or air) without isolating any target organisms, which is a complex mixture of genomic DNA and its degradation products from different organisms in the same environment. eDNA technology can reflect the community or species composition information in the ecosystem through DNA extraction and detection of environmental samples. Compared with traditional biological monitoring methods, eDNA technology has the advantages of high efficiency, high sensitivity and environmental friendliness. eDNA has been successfully used for the specific detection of Schistosoma mansoni, Schistosoma haematobium and Schistosoma japonicum. This paper reviews the current detection methods of eDNA, the application and technical limitations of eDNA technology in schistosomiasis monitoring, aiming to provide scientific reference for research in the field of schistosomiasis surveillance.
