Objective:To understand the responsiveness of community health service institutions in Henan Province. Methods:This research collected information through questionnaire investigations. The object of the investigations is key informants familiar with community health service institutions. Various dimensions of responsiveness within Henan province community health service institutions are determined through a multiple-input pecking order graph. The fuzzy comprehen-sive evaluation method is used to evaluate the level of responsiveness. Responsiveness inequality index is used to measure the distribution of reactions. Results:A total of 431 valid key informants were surveyed. The various dimensions of the questionnaire of Cronbach alpha coefficient was greater than 0. 623;the total scale of the Cronbach alpha coefficient was 0. 850;the correlation coefficient of each dimension of test-retest reliability were greater than 0. 907. The levels of responsive-ness and distribution index were 8. 33 and 0. 2744, respectively;each dimension by order of importance:timely attention>dignity>infrastructure>communication>confidentiality >social support >selective >autonomy. Approximately 50% of key informants considered that vulnerable groups in community health service institutions were sometimes or often treated unfairly. Conclusion:Key informants considered the responsiveness level of overall higher community health service institu-tions in Henan Province was high, and the distribution of responsiveness was relative equilibrium. However, there is a large shortage of infrastructure, privacy protection, doctor-patient communication, etc.

Objective To assess the efficacy of radiofrequency therapy combined with ozone injection in the treatment of lumbar disc protrusion. Methods A total of 202 patients with lumbar disk protrusion were included and divided into three groups:radiofrequency (RF) group, ozone (Oz) group, and combination (Co) group. The efficacy was evaluated by visual analogue scale (VAS), Macnab curative effect evaluation, and oswestry disability index (ODI) at 1d, 1m and 6m after treat?ment. Results There were no significant differences in gender, age, the course of disease, preoperative VAS scores and ODI scores (P>0.05). All patients were operated successfully. There were no infection of the intervertebral disc, no compli?cations of spinal cord, nerve and no blood vessel injury. There were no significant differences in preoperative VAS and ODI scores between three groups. The VAS and ODI scores were significantly lower at 6 month and 12 month after operation in Co group combined with those of RF group and Oz group. There were no significant differences in these two scores between RF group and Oz group (P>0.05). There were no significant differences in effective rates at 1d, 6 month and 12 month after operation between three groups (P>0.05). But the excellent and good effective rates were higher in Co group than those of RF and Oz groups. There were no significant differences in excellent and good effective rates between RF group and Oz group. Conclusion The therapy of radiofrequency combined with ozone injection is an efficient and mini-invasive tech?nique for the treatment of lumbar disc protrusion and worth promoting.

ObjectiveTo study the morphology, normal values and lateral asymmetry of Chinese calcarine sulcus on MRI. Methods High-resolution and transverse MRI were obtained from 40 female volunteers. Brainvisa software was used to reconstruct the calcarine sulcus and measure its average length, depth and width automatically. Results The posterior branch of calcarine sulcus showed six types in the median sagittal plane: bifurcation(32.50%), single peak(25.00%), flat (16.25%), S-shaped (15.00%), double peak(7.50%) and other shape (3.75%); its location had three types: inferior(72.50%), middle(21.25%)and superior(6.25%). The depth of left calcarine sulcus was (15.24±2.67)mm, and the right one was (16.97±3.25)mm, which revealed great statistical significance (P＜0.000 1). The width of left calcarine sulcus was (3.14±0.91)mm, and it was (3.19± 0.83)mm in the right side. The bottom length of calcarine sulcus: the left was (86.47±16.85)mm, the right was (83.62±17.10)mm. The top length of calcarine sulcus: the left was (70.52±12.40)mm, the right was (64.90±15.17)mm. There were not statistical significance in width, bottom length and top length between left and right calcarine sulci. More than half of the end part of calcarine sulci turned to the lateral surface of cerebral hemisphere.Totally 63 cases (78.75%) were found with prominent calcar avis. Conclusion Significant difference of depth between left and right calcarine sulcus of female was found. Three-dimensional reconstruction is an effective method to study the anatomy of calcarine sulcus.

Objective To analyze the fractional proteins and immunoreactivity of the soluble antigens from Babesia microti (B.microti),and find the candidate antigens for diagnosis with high sensitivity and specificity.Methods BALB/c mice were inoculated with B.microti-infected red blood cells by intraperitoneal injection.The B.microti were collected from the infected red blood cells when the infection rate reached its peak (infection rate ＞70％),then the soluble antigens were extracted by repeated freezing-thawing and ultrasonic method.The mice sera before and after the infection with B.microti for 7,14,21,28,35,42,49 and 56 days were also collected.The polyacrylamide gel electrophoresis (SDS-PAGE) was used to analyze protein components of the soluble antigens of B.microti and the Western blot was used to analyze the immunoreactivity of the soluble antigens with the pooled mice sera before and after the infection.The specific positive protein bands were identified by Liquid chromatography electrospray ionisation tandem mass spectrometry (LC-ESI-MS/MS),and the amino acid sequences of the proteins were analyzed by bioinformatics tools.Results The results from SDS-PAGE analysis indicated that the soluble antigens of B.microti showed distinct protein bands with the range between 12 and 185 × 103 (kDa,relative molecular mass,Mr),among which 9 main bands and 12 minor bands were obtained.In the Western blot analysis,the protein bands with Mr at 40 and 45 kDa could be recognized by pooled mice sera 7 days after infection;the protein bands with Mr at 40,45,54 and 95 kDa could be recognized by pooled mice sera 14 days after infection;the protein bands with Mr at 27,40,45,54,95 and 110 kDa could be recognized by pooled mice sera 21 days after infection.While,the protein bands with Mr at 27,40,45,54,95,1 10 kDa and other weak-reactive bands were recognized by pooled mice sera 28-56 days after infection,and the reaction became stronger with the infection continued.There were 336 proteins,including surface antigen,heat shock protein 70,seroreactive antigen,Eta subunit of chaperonin containing t-complex polypeptide 1 and unnamed protein products,were identified as the components of soluble antigens after mass spectrometry and sequence analysis.Conclusion The 40,45 and 54 kDa protein components from the soluble antigens of B.microti may be ideal candidate antigens for diagnosis,andtheir potential applications in diagnosing of human babesiosis deserve further study.

We discussed the influence of liquid nitrogen cryopreservation to survive capability of Babesia microti standard strain.The whole blood of mice infected with Babesia microti was put in liquid nitrogen to cryopreservation for 1 month,3 months,6 months,9 months,the whole blood was get out respectively and recovery at room temperature,and infected 3 mice respectively,100 μL/ mouse (the first generation after redissolution,the experiment group).In the same time,3 mice were also infected with Babesia microti as the animal conservation control group.When the infection rate was at a high level,the whole blood of the experiment group mice were injected into 3 normal BALB/c mice (the second generation after redissolution),to observe the changes of the Babesia microti form and proliferation situation,and also to observe the infection rate of the first and the second generation after redissolution in different conserving time.Compared with Babesia microti of animal subcultivation,the form of Babesia microti of liquid nitrogen cryopreservation changed a little.Small trophozoites,annular trophozoites,schizont and immature and mature merozoite and other form can also be seen.Compared with Babesia microti of animal subcultivation,the first time to see the worms and the time attaining to the high infection level were 1 to 2 days later,but for the second generation after redissolution,it is the same.There was no significant difference in different conserving time of 1,3,6,9 months.The influence of liquid nitrogen cryopreservation to survive capability and worm form of Babesia microti is a little,so liquid nitrogen cryopreservation can be a better way to conserving Babesia microti.

Objective To investigate the morphology and relationships with the adjacent structures in the pineal region on the thin sections and to provide anatomic data for imaging diagnosis and surgical treatment of diseases in this region. Methods By CT and MRI examination, one normal head specimen was selected for this study. Using the computerized freezing milling technique, the specimen was sliced from anterior to posterior. The in vivo MR images were obtained from ten normal Chinese male adult volunteers using a 3.0 T GE scanner. The base lines of the sectioning and the MR scan were perpendicular to the AC-PC line. Then primary sections were contrasted with the corresponding MR images. Results By the appearance of the pineal peduncle and the disappearance of the pineal gland, the pineal region could be divided into three parts from anterior to posterior, and the shape changed from an inverted triangle to a trapezoid and a triangle gradually. The first interspace was getting wider in the anterior and middle parts of the pineal region, while in the posterior part of the pineal region, it was getting narrower and disappeared finally. From anterior to posterior, the bilateral internal cerebral veins were always in the midline of the pineal region and descended gradually.Conclusion By the computerized freezing milling technique, the anatomic details and adjacent relationships of the pineal region could be exhibited clearly in the thin serial sections, which could help the imaging diagnosis and surgical treatments for minute diseases in this region.

Objective To investigate the efficacy and side effects of the molecular targeted drug sunitinib in the treatment of metastatic renal cell carcinoma(mRCC). Methods Fifteen patients with histopathological confirmed mRCC,including 10 males and 5 females,were enrolled in the study.The median age was 56(range from 37 to 73 years).Fourteen cases of clear-cell RCC and 1 papillary RCC were diagnosed.Thirteen patients had prior nephrectomy,and 6 patients were treated with cytokines previously.All of the patients were given sunitinib at a dosage of either 50 mg daily(4 weeks on/2 weeks off)or 37.5 mg daily continuously.Objective response rate(ORR),progressive-free survival(PFS)and overall survival(OS)were evaluated,and adverse events were also observed. Results The median follow-up was 13 months(2-24 months).According to RECIST,partial response could be evaluated in 8 patients and stable was found in another 5 patients.Only 2 patients were confirmed disease progression.The ORR was 53% with the disease control rate of 87%,However,the median PFS and OS were not yet available due to the short-term follow-up.During the treatment,the most common adverse events experienced by patients were hand-foot syndrome 11/15(73%),changes in hair color 10/15(67%),mucositis 9/15(60%),alopecie 9/15(60%),diarrhea 8/15(53%)and neutropenia 8/15 (53%). All of adverse events were manageable and reversible. Conclusions Sunitinib as a single agent in the treatment for Chinese mRCC patient is efficient and the side effects are reversible. Further long-term follow-up and expanded samples should be expected to confirm the efficacy and safety of sunitinib.

Objective To establish A1E3 and B1C4 monoclonal antibody-based ELISA for detecting circulating antigen of Schistosoma japonicum and explore its application value in the field. Methods The characteristics of A1E3 and B1C4 monoclonal antibodies were analyzed by SDS-PAGE and Western blotting. The SEA-based ELISA was used to evaluate the titers of A1E3 and B1C4. The orthogonal test was used to determine the best concentration of coating antibody B1C4 and optimal working concentra-tion of A1E3-HRP. Under the optimal conditions,the serum samples of 20 acute schistosomiasis cases,46 chronic schistosomiasis cases,and 20 control sera were tested to evaluate its detection sensitivity and specificity. Seventy-two antibody positive serum sam-ples from Jiangling County of Hubei Province were detected and compared to a commercially available ELISA kit,to evaluate the detection effects of this method. Results The results of SDS-PAGE demonstrated that the purified A1E3 and B1C4 contained a clear heavy chain with molecular weight of 88 000 and 52 000 respectively and had the same light chain with molecular weight of 20 000;while Western blotting demonstrated that A1E3 and B1C4 could be recognized by SEA and serum samples of acute schis-tosomiasis cases. The SEA-based ELISA demonstrated the titers of B1C4 and A1E3 were 1∶105 and 1∶30 000,respectively. The serum samples from all the acute cases and 86.9% of the chronic cases showed a positive reaction. All of the control sera from healthy persons gave a negative response. The positive rates of the double monoclonal antibody ELISA and commercial ELISA for detecting the circulating antigen were 45.8%and 43.1%respectively,and there was no significant difference between the results of the two methods. Conclusion A1E3 and B1C4 monoclonal antibody-based ELISA is established successfully. It exhibits a high sensitivity and specificity in detecting circulating antigen of Schistosoma japonicum.

Objective To establish the background information of physiological parameters for germ?free ( GF ) Taihu piglets. Methods In this study we selected 25 days old GF Taihu piglets and 4 conventional ( CV) littermates, the male and female ratio was 1∶3, to measure the normal clinical values of hematology and serum biochemistry, immunoglobu?lin concentration and main organ coefficients. The analysis of relative growths of main organ weight to body weight was con?ducted in the Taihu GF and CV pigs by allometric scaling model. Results (1) Twelve hematological parameters and 8 blood biochemical parameters in the GF piglets were significantly lower than those in CV pigs (P<0?05). (2) The aver?age body weight, IgM concentration of GF pigs and CV pigs had significant difference ( P <0?05 ) , and no mesenteric lymph nodes were found in the GF pigs. (3) The gut weight had the largest allometric association with body weight in the GF pigs, while spleen weight has the largest allometric association with body weight in the CV pigs. Both the weight of heart and stomach in CV and GF pigs had a negative allometric association with body weight (allometric coefficient b<1), respectively. Conclusions Different microbe control grades affect the body weight, hematology and serum biochemistry, expression of immunoglobulin and development of main organs in laboratory pigs.

Objective To study the application of autoregressive integrated moving average(ARIMA)model to predict the monthly reported malaria cases in China,so as to provide a reference for prevention and control of malaria. Methods SPSS 24.0 software was used to construct the ARIMA models based on the monthly reported malaria cases of the time series of 2006-2015 and 2011-2015,respectively. The data of malaria cases from January to December,2016 were used as validation data to compare the accuracy of the two ARIMA models. Results The models of the monthly reported cases of malaria in China were ARIMA(2,1,1)(1,1,0)12 and ARIMA(1,0,0)(1,1,0)12 respectively. The comparison between the predictions of the two models and actual situation of malaria cases showed that the ARIMA model based on the data of 2011-2015 had a higher ac-curacy of forecasting than the model based on the data of 2006-2015 had. Conclusion The establishment and prediction of ARIMA model is a dynamic process,which needs to be adjusted unceasingly according to the accumulated data,and in addi-tion,the major changes of epidemic characteristics of infectious diseases must be considered.
