Objective To study the expression of endogenous cystathionine-β-synthase (CBS) and hydrogen sulfide in patients with ulcerative colitis (UC), and explore their possible role in the pathogenesis of UC. Methods Thirty patients with active period UC (active period UC group), 30 patients with remission period UC (remission period UC group) and 30 healthy controls (control group) were selected, and SABC method was used to observe the localization of CBS in rectal mucosal tissues. The optical density value of CBS was analyzed with image analysis systems. The relative expression of CBS mRNA in the rectal mucosa tissue was detected by reverse transcriptase-polymerase chain reaction (RT-PCR), and the expression of glyceraldehyde-3-phosphate dehydrogenase (GAPDH) was detected as an internal reference. The expression level of mRNA was detected by semi quantitative analysis with gel imaging analysis system, and the results were expressed as the ratio of the target bands to the GAPDH absorbance. The serum level of hydrogen sulfide was detected. Results The serum level of hydrogen sulfide, optical density value of CBS and relative expression of CBS mRNA of rectal mucosal tissues in active period UC group were significantly higher than those in remission period UC group and control group: (90.13 ± 3.12) μmol/L vs. (50.34 ± 2.34) and (48.13 ± 2.75) μmol/L, 0.433 ± 0.037 vs. 0.295 ± 0.064 and 0.214 ± 0.026, 1.532 ± 0.134 vs. 1.031 ± 0.107 and 0.986 ± 0.067, and there were statistical differences (P < 0.01); but there were no statistical differences between remission period UC group and control group (P>0.05). Conclusions The abnomal expression of CBS and hydrogen sulfide in aactive period UC may play an important role in the pathogenesis of UC.

Objective To explore the correlation between myeloperoxidase (MPO) genetic variation and coal-burning endemic fluorosis, and to understand the influence of integrated intervention including stove changes and health education on people’s health in the area. Methods In 2007, coal-burning endemic fluorosis disease areas were selected in Bijie City, Guizhou Province. No stove changes in Yachi Town, 150 patients with dental fluorosis were selected as fluorosis non-intervention group, and the intervention group was 150 patients in Changchun Town where the stoves were changed 2 years ago. The population in control group was selected in an area with non-endemic fluorosis in Changshun County. The mRNA expressions of MPO in leukoxytes were detected by real-time PCR. HepG2 cells were cultured in vitro and divided into four groups: pGL3-A group, pGL3-G group, pGL3-Control group and pGL3-Basic group. pGL3-A and pGL3-G were recombinant plasmid, while pGL3-Basic as a blank control and pGL3-Control as a positive one. The internal reference plasmid pRL-TK co-transfected the HepG2 cells with pGL3-G, pGL3-A, pGL3-Basic and pGL3-Control, respectively. The influence of sudden change of MPO gene promoter on the gene transfection activity was evaluated by a dual luciferasereporter gene system. Results The expression level of MPO mRNA in peripheral blood leukocytes in non-intervention group(0.054 ± 0 . 003 ) were higher than control and intervention groups (0.019 ± 0.004,0.019 ± 0.003, all P<0.05), and no significant change was found between intervention group and control group(P>0.05). After the MPO-463G/A locus genetic variation occured, the luciferase reporter gene expression level of the recombinant plasmid pGL3-G(0.753 4 ± 0.086 6) was higher than that of the pGL3-A(0.490 0 ± 0.022 3, P < 0.05). Conclusions The study on MPO gene promoter-463G/A locus has prompted that MPO gene allele may be a protective factor to coal-burning fluorosis. The integrated interventions have a role in the prevention and treatment of endemic fluorosis.

OBJECTIVE: To observe the effect of Tiaoqi Jieyu (regulating qi and relieving depression) acupuncture on the clinical symptoms of treatment-resistant depression (TRD), and to explore the relationship between the acupuncture pain sensitivity and symptom's improvement. METHODS: A total of 78 patients with TRD were randomly divided into an observation group (39 cases, 3 cases dropped off) and a control group (39 cases, 4 cases dropped off). The patients in the control group were treated with medications according to the treatment plan of psychiatrists (at least one medication was 5-hydroxytryptamine reuptake inhibitor). On the basis of the control group, the patients in the observation group were treated with Tiaoqi Jieyu acupuncture, and Baihui (GV 20), Yintang (GV 24⁺), Yanglingquan (GB 34), Taichong (LR 3), Hegu (LI 4), Neiguan (PC 6), Yinlingquan (SP 9) and Zusanli (ST 36), etc. were selected. The acupuncture was given three times a week. Both groups were treated for 8 weeks. After 8-week treatment, the response rate of Hamilton depression scale-24 (HAMD-24) score after was evaluated in the two groups. The scores of HAMD-24 and Hamilton anxiety scale (HAMA) were compared between the two groups before treatment, after 4, 8-week treatment and 12 weeks after treatment (follow-up). After the first treatment and 8-week treatment, the visual analogue scale (VAS) score in the observation group was evaluated, and the correlation between VAS score after the first treatment and HAMD-24 score before treatment, between VAS score after the first treatment and the course of disease in the observation group was analyzed, and the correlation between difference of VAS after 8-week treatment and after the first treatment and difference of HAMD-24 score before treatment and after 8-week treatment was analyzed. RESULTS: After 8-week treatment, the response rate of HAMD-24 score in the observation group was 52.8% (19/36), higher than 17.1% (6/35) in the control group (P<0.001). Compared before treatment, the scores of HAMD-24 and HAMA in the two groups were decreased after 4-week treatment, 8-week treatment and in follow-up (P<0.05), and those in the observation group were superior to the control group (P<0.05). After 8-week treatment, the acupuncture pain VAS score in the observation group was (5.28±2.13) points, which was higher than (3.33±1.62) points after the first treatment (P<0.001). There was a negative correlation between VAS score after the first treatment and HAMD-24 score before treatment in the observation group (r =-0.486, P=0.003); there was no correlation between acupuncture pain VAS score after the first treatment and the course of disease in the observation group (P>0.05). After 8-week treatment, there was a positive correlation between the difference of VAS score and the difference of HAMD-24 score in the observation group (r =0.514, P=0.001). CONCLUSION Tiaoqi Jieyu acupuncture could improve the depression and anxiety in patients with TRD, and the symptom's improvement is related to the recovery of acupuncture pain sensitivity.

OBJECTIVETo evaluate the effect of the treatment of the lower lumbar fractures by posterior vertebral pedicle screw fixation, vertebral canal decompression,bone graft and titanium mesh reconstruction.

METHODSFrom January 2006 to December 2008, 22 patients with lower lumbar fractures were treated by posterior vertebral pedicle screw fixation, vertebral canal decompression, bone graft and titanium mesh reconstruction at same period. There were 18 males and 4 females with an average age of 43.8 years ranging from 22 to 63 years old. The injured vertebrae were L3 in 11 cases, L4, in 8 cases, and L5 in 3 cases. The operative time, blood loss, the preoperative and postoperative vertebral height,sagittal index, and the lumbar lordosis angle were recorded and evaluated.

RESULTSThe operative time was 3 to 4.2 hours (means 3.6 h). The blood loss averaged 1300 ml (900 to 1500 ml). The preoperative and postoperative sagittal index were (57.5 +/- 7.6)% and (93.5 +/- 8.1)%, respectively. The preoperative and postoperative lumbar lordosis angle were (34.3 +/- 7.3) degrees and (38.5 +/- 9.8) degrees, respectively. All patients were followed up for 10 months to 3 years (means 2.6 years). No fixation were failed,the segment of titanium mesh reconstruction obtained bone healing, no pseudoarticulation formation. At the last time of followed-up, 15 patients with nerve injuries were evaluated according to Frankel grade, there were 10 cases in grade E, 4 in D, 1 in C. According to the low back outcome scores (LBOS), the results were excellent in 20 cases, good in 1, fair in 1.

CONCLUSIONThe stability of the lower lumbar spine can be reconstructed by bone graft and titanium mesh combined with transpedicular screw fixation through a posterior approach. The decompression and vertebral body removal can also be performed in this approach. The recovery of the vertebral height and lumbar lordosis can prevent the delayed neurological deficit and traumatic kyphosis.

Objective To evaluate the efficacy and safety of terlipressin for septic shock.Methods A randomized double-blind placebo-controlled pilot study was carried out in the general ICU of the First Affiliated Hospital of Zhengzhou University from June 1st 2015 to May 31st 2016.The septic shock patients with a mean arterial pressure below 65 mmHg despite adequate volume resuscitation were enrolled.Patients were randomized (random number) to give continuous infusions of either terlipressin[0.6-2.6 μg/(kg·h)] or norepinephrine(7-30 μg/min).Open label norepinephrine or other catecholamines were additionally infused if the mean arterial pressure failed to reach 65 mmHg.Treatment was continued until shock corrected,death or withdrawn from this study.Correcting rate of shock was the primary end point,the secondary end points included open labeled norepinephrine requirements,the 28 d survival rate and adverse events.The quantitative data of the two groups were compared by t test or Wilcoxon rank sum test.The enumeration data were compared by chi square test or Fisher exact probability method,and the survival data were analyzed by Kaplan-Meier method.Results A total of 28 patients were enrolled.The full analysis set was 28,the per-protocol set was 25,and the safety set was 28.The key demographics and baseline characteristics were similar between the two groups(P＞0.05).The results for the per-protocol set were followed up.The correcting rate of shock between the two groups were similar at the end of treatment[81.82％(9/11)vs.57.14％(8/14),P=0.190].The open label norepinephrine requirements of the trial group and control group for the 0,6,12,24,48 h time point were 0.661,0.921,1.583,1.241,2.143,1.371,1.071,1.261,0.370,1.001 μg/(kg·min),respectively with no significant difference(P＞0.05).The 28 d survival rate of the trial group and control group were 63.64％(7/11)and 50.00％(7/14) respectively with no statistical significance(P＞0.05).There was no significant difference in 28 d survival analyzed using Kaplan-Meier plot between two groups(P=0.470).There were two patients with ischemia of fingers,one patient with hyponatraemia and one patient with ischemia of intestine accompanied by hyponatraemia occurred after treatment with terlipressin,and one patient with isehemia of fingers occurred after treatment with norepinephrine.The incidence of adverse event for the trial group and control group were 30.77％(4/13) and 6.67％(1/15) with no significant difference(P=0.122).Conclusions Terlipressin is an effective agent for treating septic shock.The total adverse event rate of terlipressin was similar to that ofnorepinephrine.

ObjectiveTo investigate the preventive and curative effect of Chaishao Liujunzi Tang （CSLJZT） on colonic mucosal injury induced by dextran sulfate sodium （DSS） in mice with ulcerative colitis （UC） and its mechanism. MethodFifty Balb/c male mice were randomly divided into normal group， model group， CSLJZT low-dose group， CSLJZT high-dose group， and sulfasalazine group. Except for the normal group， other groups were given 2.5% DSS freely for 7 d， and were given drug intervention after successful modeling for 7 d. Bodyweight， feces， and other general physiological statuses of mice were recorded every day， and disease activity index （DAI） scores were calculated.The colon length was measured， and stained by hematoxylin-eosin （HE） staining to observe the morphological changes of the colon.The enzyme-linked immunosorbent assay （ELISA） was used to determine the content of interleukin-1β （IL-1β）， myeloperoxidase （MPO）， and superoxide dismutase （SOD） in the serum. Western blot was used to determine the protein expression levels of Toll-like receptor 4 （TLR4）， myeloid differentiation factor 88 （MyD88）， nuclear factor kappa B （NF-κB）， inhibitor-kappa binding protein （IκB）， Caspase-1， and nucleotide-binding oligomerization domain-like receptor 3 （NLRP3） in the colon tissues. ResultAs compared with the normal group， mice in the model group had significantly decreased body weight （P<0.01）， severe diarrhea and hematochezia， and significantly increased DAI score （P<0.01）. As compared with the model group， the decreasing trend of body weight was significantly alleviated in the CSLJZT groups （P<0.01）， diarrhea and hematochezia were significantly improved， DAI score was significantly decreased （P<0.01）， and colon length increased （P<0.05）. HE staining showed that the pathological damage of colon tissue was significantly improved and the inflammatory cell infiltration was reduced in the CSLJZT groups as compared with the model group. As compared with the normal group， the serum levels of IL-1β and MPO were significantly higher （P<0.01） and SOD levels were significantly lower （P<0.01） of mice in the model group.Compared with the model group， the treated group reduced the serum IL-1β and MPO levels （P<0.01）， and raised the SOD level （P<0.01）. The results of Western blot showed that as compared with the normal group， the expression levels of TLR4， MyD88， NF-κB， Ccaspase-1， and NLRP3 proteins were significantly increased （P<0.01）， whereas the expression level of IκB protein was significantly decreased （P<0.01） in the colonic tissue of mice in the model group. As compared with the model group， the expression levels of TLR4， MyD88， NF-κB， Caspase-1， and NLRP3 proteins were decreased （P<0.01）， whereas the expression level of IκB protein was increased （P<0.01） in the colonic tissue of mice in the CSLJZT groups. ConclusionCSLJZT improves the inflammatory injury of the colon tissue in DSS-induced UC mice through TLR4/MyD88/NF-κB signaling pathway.
