OBJECTIVE:To compare therapeutic efficacies of Shengxuening tablet and Iron sucrose injection for anemia in maintenance hemodialysis(MHD)patients,and their effects on oxidative stress and micro-inflammation state. METHODS:80 pa-tients who had received MHD over half year were assigned into shengxuening group and iron sucrose group with 40 cases in each group. Both groups received MHD 3 times a week,4 h/time,blood flow of 200~300 ml/min;erythropoietin(EPO)was used at a dose of 10 000 IU/time hypodermically in each group. Shengxuening group was additionally given Shengxuening tablet orally,0.5 g/time,tid. Iron sucrose group was given Iron sucrose injection 100 mg 2 h intravenously via dialyser after the beginning of hemo-dialysis,twice a week,received iron treatment every one week until complete the total dose of 1 000 mg,to maintain ferritin be-tween 100~300 μg/L. The levels of Hb,Hct,SF,TSAT,hs-CRP,IL-6,TNF-α,MDA,SOD and GSH-Px were tested in 2 groups before and 12 weeks after the treatment. RESULTS:After 12 weeks of treatment,the levels of Hb,Hct,SF and TSAT in 2 groups were significantly increased,with statistical significance (P<0.01);but there was no statistical significance between 2 groups (P>0.05). Compared with before treatment,the levels of hs-CRP,IL-6,TNF-α and MDA increased significantly in iron sucrose group,while SOD and GSH-Px levels declined significantly,with statistical significance (P<0.01). Above indicators of shengxuening group had no significant change,compared with before treatment;there was statistical significance between 2 groups after treatment(P<0.01). No obvious ADR was found in 2 groups. CONCLUSIONS:Therapeutic efficacy of shengxuening is simi-lar to that of iron sucrose in improving the anemia and iron deficiency status of MHD patients,but doesn't aggravate oxidative stress and micro-inflammation state. It is an safe and effective oral iron supplement drugs.

OBJECTIVETo explore the clinical effects of Dynesys system for the treatment of multiple segment lumbar degenerative disease.

METHODSA total of 28 patients with lumbar degenerative disc disease treated with Dynesys system from December 2008 to May 2011 were retrospectively reviewed. There were 16 males and 12 females, aged from 27 to 75 years old with an average of 49.1 years. Thirteen patients with multiple segmental lumbar intervertebral disc protrusion, including L3-L5 in 7 cases, L2-L4 in 1 case and L4-S1 in 5 cases. Fifteen patients with multiple segmental lumbar spinal stenosis, including L3-L5 in 10 cases, L4-L5 in 4 cases and L2-S1 in 1 case. The symptoms of lumbago and (or) intermittent claudication in all patients were treated with conservative treatments for more than 6 months and these methods did not work. Visual analogue scale (VAS) was used to analyze the lumbar and leg pain, imaging data were used to measure the intervertebral space height and intervertebral motion of fixed segment and upper adjacent segment, Oswestry Disability Index (ODI) was used to evaluate the clinical effect.

RESULTSAll operations were successful and the patients were followed up from 38 to 65 months with an average 50.6 months. At final follow-up, ODI and VAS of the low back pain and leg pain were (25.10±6.52)%, (1.25±0.70) points and (1.29±0.89) points, respectively and were decreased compared with preoperative (P<0.05). Postoperative intervertebral space heights were increased and intervertebral motions were decreased in fixed segment compared with preoperative (P<0.05). There were no significant differences in intervertebral space heights and intervertebral motions of upper adjacent segment between preoperative and postoperative (P>0.05).

CONCLUSIONDynesys system may obtain long-term clinical curative effect in treating multiple lumbar degenerative disease. It can partially preserve the intervertebral motions of the fixed segments, have little effect on adjacent segments. The long-term clinical effect of Dynesys still need longer time follow-up observation.

OBJECTIVETo evaluate the clinical effects of dynamic neutralization system (K-Rod) in treating multisegmental lumbar degenerative disease.

METHODSFrom October 2011 to October 2013, 20 patients with multisegmental lumbar degenerative disease were treated with dynamic neutralization system (K-Rod). There were 8 males and 12 females with an average age of 45.4 years old (ranged from 31 to 65) and an average course of 3.8 years (ranged from 9 months to 6.25 years). All patients had the history of low back and legs pain. Among them, 10 cases were far lateral lumbar disc herniation, 7 cases were lumbar spinal stenosis, 3 cases were lumbar spondylolisthesis (degree I in 2 cases and degree II in 1 case). Every patient had only one responsible segment which causing the symptom would have to be rigidly fixed during operations, and the adjacent intervertebral disc of the responsible segments at least 1 segment has already obvious degenerated. All patients underwent the operation to relieve compressed nerves and reconstruct spinal stability with K-Rod system (the responsible segments were fixed with interbody fusion, and the adjacent segments were fixed with dynamic stabilization). Visual analogue scale (VAS), Japanese Orthopaedic Association Scores (JOA) and Oswestry Disability Index (ODI) were used to evaluate the clinical effects. Imaging data were used to analyze the range of motion (ROM), intervertebral disc height and intervertebral disc signal (according to modified Pfirrmann grading system) in degenerative adjacent segment.

RESULTSAll patients were followed up for more than 1 year, and preoperative symptoms obviously relieved. There were significant differences in VAS, JOA, ODI between preoperative and postoperative (postoperative at 1 week and 1 year) (P<0.05). Radiological examination showed that all responsible segments had already fused, and no looseness, displacement and breakage of internal fixations were found. Postoperative at 1 year, the ROM of adjacent segments were decreased (P<0.05). There was no significant difference in intervertebral disc height between preoperative and postoperative at 1 year (P>0.05). According to modified Pfirrmann grading system to classification for the 25 disks of adjacent segment, 8 disks (32%) got improvement, 15 disks (60%) got no change and 2 disks (8%) got aggravation at 1 year after operation.

CONCLUSIONDynamic neutralization system (K-Rod) combined with interbody fusion could obtain short-term clinical effects in the treatment of multisegmental lumbar degenerative disease.

Aim The effect of tetrandrine on TGF-?1 mRNA expression in glomerulosclerosis rat was observed. Methods The rats were randomly divided into four groups, such as the normal control group (sham operative rat), glomerulosclerosis model group,tetrandrine group and amlodipine group. The expression of TGF-?1 mRNA was analyzed by Northern blot hybridization. Results The expressions of TGF-?1 mRNA in two treating groups were much lower than untreated model group. There were no difference between these two treating groups. Conclusion Tetrandrine can decrease the expression of TGF-?1 mRNA in glomerulosclerosis rat induced by unilateral renctomy plus adriamycin.

OBJECTIVETo explore the effects of posterior transarticular fixation with rod-screw in treating fracture and dislocation, spinal stenosis of lower cervical vertebrae.

METHODSFrom July 2005 to July 2009,11 patients with cervical fracture and dislocation and 9 with spinal stenosis of lower cervical vertebrae underwent operation with transarticular fixation with rod-screw (Vertex system). There were 16 cases male and 4 cases female, ranging in age from 29 to 76 years with an average of 51 years. All patients underwent decompression,internal fixation and fusion through posterior approach (combined with anterior approach in 3 cases). The method of insertion of screw: the starting point located in medial 1 mm of the midpoint of the lateral mass, angle in sagittal plane was 15 degrees-20 degrees of caudal clinism and in coronal plane was 35 degrees-40 degrees of external clinism. The position of screws, the cervical array, bone graft and fusion were observed by X-ray films.

RESULTSA total of 88 transarticular screws were successfully inserted, 10 screws located in C3,4, 20 in C4,5, 32 in C5,6, 26 in C6,7. There were no complications related to screw insertion, such as injury of the vertebral artery, nerve roots and the spine cord. All patients obtained bone fusion without internal fixation breaking. The improvement rate of JOA was 55.8% at the 1st week after operation, 5 cases got excellent results, 7 good, 7 fair, 1 poor; the improvement rate of JOA was 74.5%, at the 3rd month after operation, 6 cases got excellent results, 8 good, 6 fair. There was significant difference in the JOA between before operation and at the 3rd month after operation.

CONCLUSIONThe transarticular screw fixation with rod-screw in the lower cervical spine is an effective fixation, which has advantages of rigid stability, convenience to perform, and can reduce operative risk in initial application, but the long-term follow-up is very necessary.

Objective: To study the dynamic changes of type Th22 cell immunological response during atherosclerosis process in experimental mice in order to provide a new theoretical basis for atherosclerosis therapy. Methods: 8 weeks C57BL/6J mice were divided into 2 groups: Experiment group,n=24 ApoE-/- mice and Control group, n=24 normal mice. All animals received high fat diet and the following indexes were compared between 2 groups at 0, 4, 8, 12 weeks after treatment: aortic atherosclerotic lesions were deifned by Oil red O staining, dynamic changes of Th22 cells in spleen were measured by lfow cytometry, mRNA expressions of interleukin-22 (IL-22), IL-22R1, AhR and T-bet in aorta were examined by RT-PCR, blood levels of IL-22 was detected by ELISA. Results: Compared with Control group, Experiment group had the increased area of aortic atherosclerosis (the ratio of plaque area/lumen area) and Th22 cell (CD4+ IL-22+/CD4+T cell) amount, elevated mRNA expressions of IL-22, IL-22R1, AHR, T-bet in aorta and higher blood levels of IL-22 at all time points, the differences between each time point (except 0 week) had the statistic meaning,P<0.05. In Experiment group, the differences between 2 adjacent time points, for the area of aortic atherosclerosis and mRNA expressions of AHR, T-bet: 4 weeks vs 0 week, 8 weeks vs 4 weeks, 12 weeks vs 8 weeks all had statistic meaning; for Th22 cell amount: 4 weeks vs 0 week, 8 weeks vs 4 weeks had statistic meaning and 12 weeks vs 8 weeks had no real distinction; for mRNA expressions of IL-22, IL-22R1 and blood levels of IL-22: 4 weeks vs 0 week had statistic meaning and 8 weeks vs 4 weeks, 12 weeks vs 8 weeks had no real distinctions. Conclusion: Hyperactive immunological response of Th22 cells might be involved in atherosclerosis process, the relevant mechanism should be further studied.

Objective: To explore the relationship between different temperature indicators and hospital admission for childhood pneumonia. Methods: The hospital admissions for pneumonia in children aged 0-14 years and meteorological data in Ningbo from 2015 to 2017 were collected. A distributed lag non-linear model combined with a generalized linear model was employed to analyze the exposure-response relationships between different temperature indicators（daily average,minimum and maximum temperature;the first percentile as low temperature and the 99th percentile as high temperature）and hospital admission for childhood pneumonia. Results: A total of 4 542 cases of childhood pneumonia were recruited. There were obvious seasonal fluctuations found in the inpatient volume of childhood pneumonia,which peaked in winter and bottomed in summer. After adjusting for potential confounding variables such as relative humidity,PM2.5,long term trend and seasonal trend,the results suggested that after exposed to whether low or high temperature,the inpatient volume of childhood pneumonia would increase. When the daily average temperature and daily minimum temperature were employed,the effect of high temperature on the increase of inpatient volume for childhood pneumonia was statistically significant and the cumulative relative risk for a lag of 0-7 days were 1.52（95%CI：1.04-2.23）and 1.59（95%CI：1.08-2.34）,respectively. When the daily maximum temperature was employed,the effect of low temperature on the increase of inpatient volume for childhood pneumonia was statistically significant and the cumulative relative risk for a lag of 0-7 days were 1.30（95%CI：1.02-1.66）. Conclusion Our findings suggested that an increased risk of hospital admission for childhood pneumonia was associated with both low and high temperature.
