To investigate the intervention effect and mechanism of Zhenwu Decoction on diabetic nephropathy(DN) mice of spleen-kidney Yang deficiency syndrome based on the Rho-associated coiled-coil kinase(ROCK)/IκB kinase(IKK)/nuclear factor-κB(NF-κB) pathway. Ninety-five 7-week-old db/db male mice and 25 7-week-old db/m male mice were fed adaptively for one week. The DN model of spleen-kidney Yang deficiency syndrome was induced by Dahuang Decoction combined with hydrocortisone by gavage, and then the model was evaluated. After modeling, they were randomly divided into a model group, high-dose, medium-dose, and low-dose Zhenwu Decoction groups(33.8, 16.9, and 8.45 g·kg~(-1)·d~(-1)), and an irbesartan group(25 mg·kg~(-1)·d~(-1)), with at least 15 animals in each group. The intervention lasted for eight weeks. After the intervention, body weight and food intake were measured. Serum crea-tinine(Scr), blood urea nitrogen(BUN), fasting blood glucose(FBG), urinary albumin(uALb), and urine creatinine(Ucr) were determined. The uALb/Ucr ratio(ACR) and 24 h urinary protein(UTP) were calculated. Renal pathological morphology was evaluated by HE staining and Masson staining. The levels of key molecular proteins in the ROCK/IKK/NF-κB pathway were detected by Western blot. Enzyme-linked immunosorbent assay(ELISA) was used to detect interleukin-1β(IL-1β), interleukin-6(IL-6), interleukin-8(IL-8), interleukin-10(IL-10), and tumor necrosis factor-α(TNF-α). Compared with the blank group, the model group showed increased content of BUN, uALb, and SCr, increased values of 24 h UTP and ACR, decreased content of Ucr(P<0.05), enlarged glomeruli, thickened basement membrane, mesangial matrix proliferation, inflammatory cell infiltration, and collagen fiber deposition. The protein expression of ROCK1, ROCK2, IKK, NF-κB, phosphorylated IKK(p-IKK), phosphorylated NF-κB(p-NF-κB), and phosphorylated inhibitor of NF-κB(p-IκB) increased(P<0.05), while the protein expression of inhibitor of NF-κB(IκB) decreased(P<0.05). The levels of inflammatory factors IL-1β, IL-6, IL-8, and TNF-α increased(P<0.05), while the level of IL-10 decreased(P<0.05). Compared with the model group, the groups with drug treatment showed decreased levels of BUN, uALb, SCr, 24 h UTP, and ACR, increased level of Ucr(P<0.05), and improved renal pathological status to varying degrees. The high-and medium-dose Zhenwu Decoction groups and the irbesartan group showed reduced protein expression of ROCK1, ROCK2, IKK, NF-κB, p-IKK, p-NF-κB, and p-IκB in the kidneys(P<0.05), increased protein expression of IκB(P<0.05), decreased levels of serum inflammatory factors IL-1β, IL-6, IL-8, and TNF-α(P<0.05), and increased level of IL-10(P<0.05). Zhenwu Decoction can significantly improve renal function and renal pathological damage in DN mice of spleen-kidney Yang deficiency syndrome, and its specific mechanism may be related to the inhibition of inflammatory response by down-regulating the expression of key molecules in the ROCK/IKK/NF-κB pathway in the kidney.

Background:Clinical outcomes of undifferentiated arthritis (UA) are diverse,and only 40 ％ of patients with UA develop rheumatoid arthritis (RA) after 3 years.Discovering predictive markers at disease onset for further intervention is critical.Therefore,our objective was to analyze the clinical outcomes of UA and ascertain the predictors for RA development.Methods:We performed a prospective,multi-center study from January 2013 to October 2016 among Chinese patients diagnosed with UA in 22 tertiary-care hospitals.Clinical and serological parameters were obtained at recruitment.Follow-up was undertaken in all patients every 12 weeks for 2 years.Predictive factors of disease progression were identified using multivariate Cox proportional hazards regression.Results:A total of 234 patients were recruited in this study,and 17 (7.3％) patients failed to follow up during the study.Among the 217 patients who completed the study,83 (38.2％) patients went into remission.UA patients who developed RA had a higher rheumatoid factor (RF)-positivity (42.9％ vs.16.8％,x2=8.228,P=0.008),anti-cyclic citrullinated peptide (CCP) antibodypositivity (66.7％ vs.10.7％,x2 =43.897,P ＜ 0.001),and double-positivity rate of RF and anti-CCP antibody (38.1％ vs.4.1％,x2 =32.131,P ＜ 0.001) than those who did not.Anti-CCP antibody but not RF was an independent predictor for RA development (hazard ratio 18.017,95％ confidence interval:5.803-55.938;P ＜ 0.001).Conclusion:As an independent predictor of RA,anti-CCP antibody should be tested at disease onset in all patients with UA.

BACKGROUND: The X-ray 9-point grading system is established based on cervical disc degeneration and its suitability for evaluation of lumbar disc degeneration has not been validated. OBJECTIVE: To investigate the feasibility of the evaluation of lumbar intervertebral disc degeneration using the 9-point grading system with X-ray, and to explore its clinical application value. METHODS: The correlation between 9-point grading system and Pfirrmann system was statistically analyzed. Magnetic resonance imaging (MRI) and X-ray images of 172 cases with lumbar disc degeneration or simple lumbago, who were treated in the Shanghai Changzheng Hospital from June 2013 to June 2016, were retrospectively analyzed. The MRI scores of lumbar disc degeneration were evaluated according to Pfirrmann standard, and the X-ray scores were evaluated according to 9-point grading system. The two groups of scores were respectively analyzed by the correlation and regression tests via Spearman rank sum test with SPSS software. RESULTS AND CONCLUSION: (1) MRI scores (the independent variable X): 2 cases scored 1; 8 cases scored 2; 55 cases scored 3; 84 cases scored 4; 23 cases scored 5. X-ray scores (the dependent variable Y): 2 cases scored 0; 6 cases scored 1; 21 cases scored 2; 43 cases scored 3; 40 cases scored 4; 26 cases scored 5; 16 cases scored 6; 8 cases scored 7; 7 cases scored 8; 3 cases scored 9. (2) The Spearman correlation test showed that significant positive correlation was found between Pfirrmann system and 9-point grading system (P <0.01). Significance test of correlation coefficient proved that there was significant linear correlation between Pfirrmann system and 9-point grading system. Further regression analysis showed the linear regression between Pfirrmann system and 9-point grading system. (3) These findings suggested that Pfirrmann system and X-ray 9-point grading system had a good consistency in evaluating lumbar disc degeneration. As a scientific, fast and effective evaluation method, the X-ray 9-point grading system has a certain reference value in the diagnoses of lumbar degenerative diseases.

AIM To observe the changes of serum ROS,MDA,SOD levels in chronic renal failure (CRF) patients with damp-heat syndrome and to explore the intervention effect of Qingshen Granules (Hedyotis diffusae Herba,Salviae miltiorrhizae Radix et Rhizoma,Artemisiae scopariae Herba,etc.) on oxidative stress.METHODS Seventy cases of CRF patients with damp-heat syndrome were randomly and equally divided into control group and treatment group.Sixty cases completed the study,thirty-one cases in the treatment group,twenty-nine cases in the control group.Twenty other cases served as the normal group.The treatment group and the control group were given the basic treatment of western medicine and retention enema of TCM.The treatment group was added Qingshen Granules for eight weeks.The levels of U-Pro/24 h,Scr,BUN,estimated glomerular filtration rate (eGFR),serum ROS,MDA and SOD were measured before and after the treatment,and were compared with the normal group.RESULTS Both total effective rates on disease and on traditional Chinese medicine syndrome in the treatment group were 83.87％,significantly higher than those in the control group (51.72％ and 48.28％),respectively.The levels of U-Pro/24 h,Scr and BUN were obviously lower in the treatment group after the treatment,and eGFR was obviously higher as compared with those in the control group.Before the treatment,the levels of ROS and MDA in the treatment and control groups were significantly higher than those in the normal group,and the level of SOD was significantly lower;the levels of ROS and MDA were reduced in the treatment group after the treatment,and the level of SOD was increased;these changes in the treatment group were more significant than those in the control group.CONCLUSION Qingshen Granules can ameliorate clinical symptoms in CRF patients with damp-heat syndrome,decrease the levels of U-Pro/24 h,Scr and BUN,increase eGFR level,inhibit oxidative stress,and enhance antioxidant capacity,ultimately delay the development of renal fibrosis.

Objective:To analyze the clinical features of ankylosing spondylitis (AS) with traumatic cervical fracture-dislocation ,and discuss the crucial considerations of surgical treatment . Methods: The data of 9 patients of ankylosing spondylitis with traumatic cervical fracture-dislocation treated in Changzheng Hospital from January 2013 to April 2015 were analyzed ,and the clinical data ,follow-up data and imaging results were summarized .Results:The average course of disease was (20 .3 ± 9 .4) years .There were 4 cases of grade C and 5 cases of grade D according to the Frankel grading .There were five anterior operations ,two posterior operations and two combined anterior-posterior operations .All cases were followed up for 12-24 months (mean [16 .1 ± 3 .5] months) .Postoperative neurological function was improved in all patients ,perioperative complications included cerebral spinal fluid leakage in one case and incision deep infection in one case .There were no fracture nonunion ,pseudarthrosis and internal fixation failure .Conclusions:Because of local stress concentration and poor stability of AS with cervical fracture-dislocation ,we should actively implement surgical treatment to rebuild spinal stability and lower the probability of occurrence of spinal cord injury .Meanwhile ,perioperative management should be strengthened to avoid the secondary spinal cord injury .

BACKGROUNDData on the epidemiology of hypertension in Chinese non-dialysis chronic kidney disease (CKD) patients are limited. The aim of the present study was to investigate the prevalence, awareness, treatment, and control of hypertension in the non-dialysis CKD patients through a nationwide, multicenter study in China.

METHODSThe survey was performed in 61 tertiary hospitals in 31 provinces, municipalities, and autonomous regions in China (except Hong Kong, Macao, and Taiwan). Trained physicians collected demographic and clinical data and measured blood pressure (BP) using a standardized protocol. Hypertension was defined as systolic BP ≥ 140 mmHg and/or diastolic BP ≥ 90 mmHg, and/or use of antihypertensive medications. BP < 140/90 mmHg and < 130/80 mmHg were used as the 2 thresholds of hypertension control. In multivariate logistic regression with adjustment for sex and age, we analyzed the association between CKD stages and uncontrolled hypertension in non-dialysis CKD patients.

RESULTSThe analysis included 8927 non-dialysis CKD patients. The prevalence, awareness, and treatment of hypertension in non-dialysis CKD patients were 67.3%, 85.8%, and 81.0%, respectively. Of hypertensive CKD patients, 33.1% and 14.1% had controlled BP to < 140/90 mmHg and < 130/80 mmHg, respectively. With successive CKD stages, the prevalence of hypertension in non-dialysis CKD patients increased, but the control of hypertension decreased (P < 0.001). When the threshold of BP < 130/80 mmHg was considered, the risk of uncontrolled hypertension in CKD 2, 3a, 3b, 4, and 5 stages increased 1.3, 1.4, 1.4, 2.5, and 4.0 times compared with CKD 1 stage, respectively (P < 0.05). Using the threshold of < 140/90 mmHg, the risk of uncontrolled hypertension increased in advanced stages (P < 0.05).

CONCLUSIONSThe prevalence of hypertension Chinese non-dialysis CKD patients was high, and the hypertension control was suboptimal. With successive CKD stages, the risk of uncontrolled hypertension increased.

Objective To explore the value of hippocampus hydrogen proton magnetic resonance spectrum analyzes (1 H-MRS) for the diagnosis of temporal lobe epilepsy (TLE) in children.Methods Singa HDe GE company to attain the 1.5T magnetic resonance imaging apparatus was used to analyze the conditions of 30 cases of children with TLE and the other 30 healthy controls received brain MRI and 1H-MRS check.The hippocampal N acetyl aspartate (NAA),creatine (Cr),and the choline (Cho) concentration were observed; NAA/(Cho + Cr),the ratio of NAA/Cr and NAA/Cho were analyzed.The analysis of biochemical components in the hippocampus was performed on the affected sides and the healthy sides of TLE group and the sides of the healthy control group,respectively.Results Hippocampus were anormal by combining MRI and MRS in 28 cases.Levels of NAA/(Cho + Cr),NAA/Cho,and NAA/Cr in the trouble sides of the TLE group had the remarkable statistical significance compared with the normal sides,and the healthy control group (all P ＜ 0.05),but there was no remarkable statistic significance between the normal sides and the healthy control group (all P ＞ 0.05).Nineteen cases had been confirmed by surgery,and postoperative pathological changes:brain surface were wavy,cortex were uneven;there were giant neurons,immature neurons,and scattered across the deformity of neurons in the cortex.A small amount of ectopic neurons can be seen in white matter.Conclusions In the TLE children,the reduction of NAA/(Cho + Cr) value of the side hippocampus may help diagnose the hipppcampal sclerosis earlier,and can provide significant evidence for the diagnosis and treatment of TLE in children.

OBJECTIVETo observe the short-term clinical results of the adjacent segment degeneration after the implantation of Coflex system at the interspinous space of adjacent segment to lumbar fusion.

METHODSFifty patients with grade III disc (Thompson MRI classification) of adjacent segment to lumbar fusion were included and divided alternately into two groups according to the order of hospitalization from January to November 2009. Coflex system was implanted at the interspinous space of adjacent segment to lumbar fusion in 25 patients as Coflex group, the other 25 patients did not have any surgical treatment were as control group. The followed up time was 2 years. Visual analogue scale (VAS) score of low back pain, changes of disc height and motion range of adjacent segment to lumbar fusion on X-ray imaging were evaluated by independent sample t-test or paired samples t-test.

RESULTSThere were 22 patients in Coflex group and 21 patients in control group were followed up 2 years post-operation. The difference of VAS score between two groups was no significance (P > 0.05). In Coflex group, the change of postoperative disc height was no significance (P > 0.05), but the motion range was significantly reduced to 47% of the preoperative value (t = 7.99, P < 0.05). In control group, the postoperative disc height decreased slightly, without significant difference to the preoperative value (P > 0.05). Between the two groups, no differences of the disc height and motion range were found before operation, but the differences of the disc height changes (t = 6.7, P < 0.05) and motion rang (t = -14.5, P < 0.05) were significant in 2 years post-operation. No complications such as Coflex system loosen, immigration and spinal process fracture were occurred.

CONCLUSIONSCoflex system can obviously limit the motion range and maintain the disc space height of adjacent segment to lumbar fusion, and prevent its degeneration in some degree.
