Objective To evaluate the effectiveness of a whole-process health education model among inpatients with ascites type of advanced schistosomiasis. Methods A “admission-hospitalization-discharge” whole-process health education model was created, 101 inpatients with ascites type of advanced schistosomiasis were given the whole-process health education. The scores of schistosomiasis control knowledge, attitudes towards schistosomiasis control and healthy behaviors, and awareness of schistosomiasis control knowledge, correct rate of attitudes towards schistosomiasis control and correct rate of healthy behaviors were compared among inpatients with ascites type of advanced schistosomiasis before and after implementation of the whole-process health education. Results The scores of schistosomiasis control knowledge, schistosomiasis control attitudes and healthy behaviors were all significantly higher among inpatients with ascites type of advanced schistosomiasis after implementation of the whole-process health education than before implementation (Z = −7.688, −3.576 and −4.328, all P values < 0.01). In addition, the awareness of schistosomiasis control knowledge increased from 54.3% to 82.7% (χ² = 188.886, P < 0.01), and the correct rate of attitudes towards schistosomiasis control increased from 88.4% to 98.0% (χ² = 22.001, P < 0.01), while the correct rate of healthy behaviors increased from 48.2% to 59.7% (χ² = 11.767, P < 0.01). Conclusions The whole-process health education model may remarkably improve the awareness of schistosomiasis control knowledge and promote the formation of positive attitudes towards schistosomiasis control and correct behaviors among inpatients with ascites type of advanced schistosomiasis, which is of great significance to facilitate patients’ cure.

Objective:To explore the molecular mechanism of Jiangtang Xiaozhi tablets （JTXZT） in the treatment of non-alcoholic fatty liver disease （NAFLD） by means of network pharmacology and molecular docking. Method:With the help of traditional Chinese medicine （TCM） Systems Pharmacology Database and Analysis Platform （TCMSP）， TCMs Integrated Database （TCMID）， Encyclopedia of TCM （ETCM） and Bioinformatics Analysis Tool for Molecular Mechanism of TCM （BATMAN-TCM）， the chemical compositions of medicinal materials in JTXZT were obtained， the compound targets were predicted in SwissTargetPrediction database and STITCH database. The targets of NAFLD were searched by The Human Gene Database （GeneCards）， Online Mendelian Inheritance in Man （OMIM）， Therapeutic Target Database （TTD） and DisGeNET， and intersection analysis was performed with the targets of the active ingredients to obtain the targets of JTXZT for treatment of NAFLD. Based on STRING 11.0 database， the protein-protein interaction （PPI） network of therapeutic targets was constructed， and the enrichment analysis of therapeutic targets was carried out by DAVID 6.8. Finally， the interaction characteristics of key components and core therapeutic targets of JTXZT for treatment of NAFLD were verified based on molecular docking. Result:The key components of JTXZT for treatment of NAFLD were quercetin， luteolin， kaempferol， berberine， isorhamnetin， betulinic acid， oleanolic acid， ursolic acid. formononetin and hexitol， and the core targets of JTXZT for treatment of NAFLD were mitogen-activated protein kinase 1 （MAPK1）， Jun proto-oncogene， activator protein-1 （AP-1） transcription factor subunit （JUN）， MAPK3， protein kinase B1 （AKT1 or Akt1）， tumor protein p53 （TP53）， E1A binding protein p300 （EP300）， Fos proto-oncogene， AP-1 transcription factor subunit （FOS）， tumor necrosis factor （TNF），amyloid beta precursor protein （APP） and cytochrome P450 family 2 subfamily E member 1 （CYP2E1）. Biological function and pathway enrichment analysis showed that JTXZT mainly through xenobiotic metabolic process， oxidation-reduction process， cholesterol metabolic process and other biological processes， regulating phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt） signaling pathway， MAPK signaling pathway， NAFLD and insulin signaling pathway to play a role in the treatment of NAFLD. The results of molecular docking showed that the active components of JTXZT had a good affinity with the core targets of JTXZT for the treatment of NAFLD. Conclusion:JTXZT treats NAFLD through multiple active components， multiple key targets and multiple action pathways.

Objective To predict the changes in the prevalence of Schistosoma japonicum infections in humans and livestock in Hunan Province using the exponential smoothing model and the ARIMA model. Methods The data pertaining to S. japonicum infections in humans and livestock in Hunan Province from 1957 to 2015 were collected, and the exponential smoothing model and the ARIMA model were created using the software Eviews and PASW Statistics 18.0. In addition, the effectiveness of these two models for the prediction of S. japonicum infections in humans and livestock in Hunan Province from 2016 to 2018 was evaluated. Results The exponential smoothing model and the ARIMA model had a high goodness of fit for prediction of S. japonicum infections in humans and livestock in Hunan Province from 1957 to 2015. There was a linear trend in the prevalence of S. japonicum infections in humans and livestock in Hunan Province from 1957 to 2015. The prevalence of S. japonicum infections in humans predicted with the Brown’s linear trend and the prevalence of S. japonicum infections in livestock predicted with the Holt’s linear trend in Hunan Province from 2016 to 2018 fitted better the actual data than the ARIMA model; however, prediction of the ARIMA model indicated that the endemic situation of schistosomiasis remained at a low level in Hunan Province. Conclusion At a low epidemic level, development of highly sensitive tools for monitoring schistosomiasis is urgently needed in Hunan Province to fit the current endemic situation, and the schistosomiasis control measures should be intensified to consolidate the control achievements.

As an ancient parasitic disease, schistosomiasis has been endemic in Dongting Lake areas for more than 2 100 years. In the early 20th century, the first human case of schistosomiasis in China was reported in Dongting Lake areas, which was paid extensive attention. After the founding of the People’s Republic of China, large-scale schistosomiasis control activities were launched promptly in Dongting Lake areas, and great successes have been achieved following the three stages of control efforts, including the snail control-based stage, synchronous chemotherapy for humans and livestock-based control stage and infectious source control-based control stage. In 2015, transmission control of schistosomiasis was achieved in Hunan Province. This paper comprehensively describes the discovery and control of schistosomiasis, analyzes the challenges for the current schistosomiasis control programs and proposes the emphasis for future control activities in Dongting Lake areas, so as to provide insights into the schistosomiasis control program in this area.

This work was designed to investigate proteins differentially expressed in cultivated Pseudostellaria heterophylla and its wild type using iTRAQ proteomics approach. The extracted proteins were digested using FASP method and identified by iTRAQ coupled with LC-MS/MS technology and then analyzed by Protein Pilot 5.0 search engine. Proteins differentially expressed were searched through comparison of relatively quantified proteins. The analysis was conducted using GO (gene ontology), KEGG and STRING. A total of 3 775 proteins were detected, among them, 3 676 proteins can be quantified, of which 127 proteins were up-regulated and 205 were down-regulated in cultivated Pseudostellaria heterophylla. We found 71 significantly differentially expressed proteins for further analysis. These proteins were classified into nine categories:heat shock proteins, transferases, oxidoreductases, lyases, isomerases, ligases, hydrolases, tubulin and translocases. The results indicated that the carbohydrate and cellular amino acids metabolism of cultivated Pseudostellaria heterophylla were weaker than its wild type and its ability of responding to stress was much stronger. GWD1, PHS1, GBE1, PGM, and BAM1 are the important proteins to regulate sucrose; metE and CYS are the key proteins that regulate amino acids in cultivated and wild Pseudostellaria heterophylla. This will provide the basic information for exploring the cause of secondary metabolites differences in different ecotype of Pseudostellaria heterophylla and the protein mechanism of its quality formation.

OBJECTIVETo evaluate the accuracy and safety of pedicle screw insertion with the aid of novel patient-specific drill-guide templates in scoliosis cases.

METHODSTen patients with scoliosis were selected to participate in the research (the observation group) from December 2013 to December 2014. The data was obtained from CT scanning, and put into the computer to perform reconstruction of spine, simulation of pedicle screw insertion, and design of patient-specific drill-guide templates with software. The templates were made with rapid prototyping technique. After sterilization, the templates were used to aid the pedicle screw insertion intraoperatively. The blood loss, operation duration, change of creatinine level pre- and post-operation, and complications related to pedicle screw insertion were recorded. The location of pedicle screws were graded so as to evaluate the accuracy. A comparative study was then performed with the data of ten scoliosis cases operated with free-hand method during the same period (control group). There were 5 cases of idiopathic scoliosis and 5 cases of congenital scoliosis in the observation group, including 3 males and 7 females. Their average age was 11.9 years old (ranged, 4 to 18 years old), and the average Cobb angle of main curve was 54.9° (ranged, 42.1° to 78.4°). There were also 5 cases of idiopathic scoliosis and 5 cases of congenital scoliosis in the control group,including 2 males and 8 females. Their average age was 12.6 years old (ranged, 6 to 17 years old), and the average Cobb angle of main curve was 56.6° (ranged, 38.2° to 93.4°).

RESULTSA total of 167 pedicle screws were inserted intraoperatively, with 138 screws (82.6%) in grade I, 26 screws (15.0%) in grade II, 4 screws in grade III (2.4%), but no screws in grade IV according to the CT image. There were 29 (17.4%) screws perforated, and 163 (97.6%) screws could be accepted. In the control group, a total of 165 pedicle screws were inserted intraoperatively, with 98 screws (59.4%) in grade I, 39 screws (23.6%) in grade II, 21 screws in grade III (12.7%), and 7 screws in grade IV (4.2%). There were 67 (40.6%) screws perforated, and 137 (83.0%) screws could be accepted. The grade distribution of screw position, ratio of perforated and accepted screws were significantly different between the two groups respectively (Z=-5.013, P=0.000; χ2=9.347, P=0.002; χ2=20.242, P=0.000). The correction rate of Cobb angle were (74.1±10.0)% vs (69.7±17.6)%; blood loss were (455±447) ml vs (415±389) ml; operation duration were (163.5±53.7) min vs (164.0±48.7) min; and the changes of creatinine level pre- and post-operatively were (-5.3±3.2) μmol/L vs (-3.4±3.1) μmol/L; all above data had no significant differences respectively (t=0.696, P=0.496; t=0.214, P=0.833; t=0.022, P=0.983; t=1.375, P=0.192). There were no complications related to pedicle screw insertion in each group.

CONCLUSIONThe novel patient-specific drill guide template can be used to assist the insertion of pedicle screws in scoliosis cases with much higher accuracy than that of freehand method and fair safety.

OBJECTIVETo investigate retrospectively the clinical effects and recurrence rate of 143 cases who underwent one level discectomy and followed up more than 10 years. To evaluate the outcome of patients in groups of different operating age and extents of disc herniation, and analyse whether difference exists in each group.

METHODSThere were 143 patients (operation time from January 1996 to December 2000) including 80 males and 63 females, aged from 18 to 66 years old with an average of 37.85 years. The followed-up time was 10 to 15 years with an average of 12.7 years. Patients were divided into 3 groups depends on operating age: < 30 years old, 30 to 50 years old and > 50 years old; 87 patients who's pre-operative CT scan could be collected among 143 cases were divided into 3 groups depends on extents of disc herniation: I degree, II degrees, and III degrees. The final followed-up was obtained in 2011, to evaluate each group and the holistic clincal outcome with JOA scores and ODI scores, and observe whether there were difference between every groups; to judge the effects by patient himself with modified Macnab Criteria.

RESULTS(1) JOA scores pre-operation and final followed-up was 5.11 +/- 2.02 and 12.51 +/- 2.35 respectively; ODI scores pre-operation and final followed-up was 33.98 +/- 7.42 and 13.39 +/- 6.79 respectively. There were significant differences between pre-operative and final followed-up in JOA and ODI (P < 0.01). The excellent-good rate was 83.2% (119/143 ) according to modified Macnab Classification with recurrence rate of 6.3% at final follow-up. (2) Obvious difference was found in JOA scores in group who's age at operation less than 30 years old compared with other 2 groups at followed-up time, and no significant difference was found in JOA scores between other two groups ; no significant difference was found in ODI scores among the three groups. (3) Significant difference was found in JOA and ODI scores in group with III degrees lumbar disc herniation group compared with other 2 groups, and no statistical difference was found in clincal scores between other 2 groups.

CONCLUSION(1) Long-term followed-up of 143 cases prove mono-level lumbar discectomy is an option for disc herniation with good curative effect and lower recurrent rate, the technique should be the prior selection in dealing with patients with lumbar disc herniation. (2) 51% patients (19/37) in group under 30 years old endure persistent low back pain. (3) The long-term clinical effects in patients with severe disc protrution who underwent lumbar discectomy is worse than those patients with mild lumbar disc herniation.

OBJECTIVETo measure the diameter of T4 pedicle-rib compomers in normal human spines and discuss the importance of related dates.

METHODST4 computerized tomography (CT) images,including two-dimensional,three-dimensional reconstruction, of 12 random adult patients were harvested. There were 7 males and 5 females with a mean age of 23 years (ranged, 19 to 28 years). The patients were divided into groups by self control,which means the diameter of pedicle compared with that of pedicle-rib unit in the same side of each T4. The facility was GE light speed 16. Measurement of the body specimens from T3 to T5 . The parameter included the width of pedicle-rib unit compared with pedicle,the longitudinal diameter of pedicle-rib unit compared with pedicle, especially for the pedicle-rib overlap.

RESULTSThe relationship of T4 pedicle and rib were not on the same level but overlapping. The width of pedicle-rib unit was significantly larger than that of pedicle (P<0.05). The longitudinal diameters of pedicle-rib unit or pedicle were significantly larger than those of pedicle-rib overlap (P<0.05); while there was no significantly difference between the pedicle-rib unit and pedicle (P>0.05).

CONCLUSIONThe overlapping relationship of T4 pedicle and rib is partly but not whole, which means the longitudinal diameter of T4 pedicle-rib overlap should not be considered as the same of unit or pedicle.

OBJECTIVESTo retrospectively investigate the outcome of transpedicular intracorporeal grafting and posterolateral grafting in treatment of thoracolumbar burst fractures.

METHODSForty-six patients treated with transpedicular intracorporeal grafting from January 1999 to December 2009 and followed up for 19-119 months (average 67 ± 13 months) were reviewed retrospectively, and were compared with 18 patients who had underwent posterolateral fusion during the same period through radiographic analysis. Radiographic measurements included Cobb angle, vertebral wedge angle (VWA), ratio between anterior and posterior vertebral height (APHR), upper inter-vertebral angle, lower inter-vertebral angle on X-ray, CT and MRI.

RESULTSIn transpedicular intracorporeal grafting group, the VWA was corrected from 27.2° ± 6.5° to 7.0° ± 3.0° and the APHR from (53.3 ± 11.8)% to (92.3 ± 2.4)%. In posterolateral fusion group, the VWA was corrected from 23.9° ± 4.4° to 8.8° ± 2.1° and the APHR from (60.7 ± 10.0)% to (88.5 ± 3.3)%. Transpedicular intracorporeal grafting group showed better postoperative correction results than posterolateral fusion group (P < 0.05), and had less loss of correction of Cobb angle, VWA and APHR at final follow-up (P < 0.05).

CONCLUSIONSThe transpedicular intracorporeal grafting can improve injured vertebral body morphology recovery better than posterolateral bone grafting, but can not prevent the late loss of correction after implant removal.
