OBJECTIVETo investigate the efficacy and safety of compound plantain-senna granule (CPSG) in the treatment of functional constipation.

METHODSEighty patients with confirmed diagnosis of functional constipation were assigned to 2 groups. The 40 patients in the treatment group were treated with CPSG 5 g per day, while the 40 patients in the control group were treated with equal volume of starch granule, for 2 weeks totally. The defecating frequency and stool property, the scores of fecal discharge difficulty and accompanied symptoms, the gastrointestinal transmission time, and adverse reaction of treatment in the two groups were observed before and after treatment.

RESULTSParameters of defecating frequency, stool property, the scores of fecal discharge difficulty, accompanied symptoms and the gastrointestinal transmission time were unchanged after treatment in the control group (P > 0.05); while in the treatment group, they improved significantly (P < 0.05) and showed significant difference to those in the control group respectively (P < 0. 05). No serious adverse reaction occurred in both groups.

CONCLUSIONCPSG can obviously increase the defecating frequency, change the stool property, alleviate the fecal discharging difficult symptom and accompanied symptom, and shorten the gastrointestinal transmission time in patients with functional constipation with good security and tolerability.

OBJECTIVETo explore the protective effects of bicyclol against renal interstitial fibrosis and possible mechanisms of the protection.

METHODSEighty-one Sprague-Dawley (SD) rats were randomly assigned to a sham-operated group and UUO groups with and without bicyclol treatment. A rat model of renal interstitial fibrosis was prepared by unilateral ureteral obstruction (UUO). Renal tissues were examined by hematoxylin & eosin and Masson staining on 7, 14 and 21 days. Immunhistochemistry was used for determining plasminogen activator inhibitor-1(PAI-1) expression in the renal interstitium. PAI-1 mRNA expression in renal tissues was semi-quantitatively determined by reverse transcription-polymerase chain reaction (RT-PCR).

RESULTSThe relative areas of renal interstitial fibrosis in the bicyclol-treated UUO group 7, 14 and 21 days after operation were (9.6 ± 0.6)%, (16.8 ± 0.8)% and (33.6 ± 1.6)% respectively, which were significantly lower than those in the untreated UUO group [13.0 ± 0.7)%, (25.8 ± 1.5)% and (53.2 ± 2.5)% respectively] (P<0.05). The levels of protein and mRNA expression of PAI-1 in the bicyclol-treated UUO group decreased significantly compared with those in the untreated UUO group 7, 14 and 21 days after operation (P<0.05).

CONCLUSIONSBicyclol can alleviate renal interstitial injury and renal interstitial fibrosis caused by UUO in rats, possibly through a downregulation of renal PAI-1 expression.

AIM: To assess the clinical efficacy of phacoemulsification, intraocular lens implantation with goniosynechialysis(PEI+GSL)for acute angle closure glaucoma(AACG)and cataract with extensive angle closure synechiae.

METHODS: A retrospective study, we studied 35 eyes of 32 patients with AACG and cataract in our hospital. The extent of anterior chamber angle-closure synechiae was defined as an eye with >180°. All patients underwent PEI+GSL and completed an ophthalmologic examination including vision, intraocular pressure(IOP), anterior chamber depth(ACD), angle-opening distance(AOD500), trabecular-iris space area(TISA500)were observed at 1d, 1wk, 1mo and 3mo after cataract surgery. The angle closure range and retinal nerve fiber layer(RNFL)thickness changes at postoperative 1mo and 3mo were observed, and recorded complications.

RESULTS: Postoperative 3mo BCVA(0.334±0.154)and IOP(14.63±3.59mmHg)were improved compared with preoperative(0.914±0.290, 42.54±8.06mmHg)(P<0.05). ACD(3.203±0.214mm), OCT angle parameters AOD500 and TISA500(0.308±0.014, 0.315±0.015mm, 0.134±0.013, 0.139±0.018mm2)were significantly increased compared with preoperation. The extent of angle closure with gonioscopy(72.32±28.33°)decreased compared preoperation(215.29°±30.66°), and RNFL thickness thinner than preoperation(P<0.001). Changes in AOD500 and TISA500 for both nasal and temporal were negatively correlated with IOP, but not with changes in ACD, and no significant complications occurred in the 3mo after surgery.

CONCLUSION: The treatment of PEI+GSL can improve vision, deeper ACD and effectively open ACA in the early stage, thus controlling IOP.

Tumor invasion and metastasis are the main factors leading to poor prognosis of cancer patients.In recent years, studies have found that collagen fiber remodeling in extracellular matrix(ECM) can promote tumor invasion and metastasis . Lysine hydroxylase 2(PLOD2) is the only lysine hydroxylase that changes the pattern of collagen fiber cross-linking and remodeling. It is highly expressed in many tumors and is closely related to tumor invasion and metastasis,Therefore, in-depth study of the role and mechanism of PLOD2 in tumor metastasis is of great scientific value for judging tumor prognosis and preventing tumor invasion and metastasis.This article reviews the recent advances in the role and potential mechanisms of PLOD2 in tumor invasion and metastasis.

OBJECTIVE: To investigate the correlation between Helicobacter pylori (H. Pylori) infection and polymorphism of adiponectin gene promoter -11391G/A, extracellular superoxide dismutase (EC-SOD) gene in nonalcoholic fatty liver disease (NAFLD).
 METHODS: From June, 2010 to July, 2014, a hospital-based 1:1 matched case-control study was carried out, with 600 cases of NAFLD and 600 healthy people in the First Affiliated Hospital of Xinxiang Medical University. The genetic polymorphisms of adiponectin gene promoter -11391G/A and EC-SOD were analyzed by polymorphism-polymerase chain reaction (PCR) technique in peripheral blood leukocytes of the subjects. 14C-urea breath test (14C-UBT) was used to test 14C disntegration per minute (DPM) for evaluating the infections status of H. Pylori. The synergistic effect between the two mutants and the gene-environment interaction of the genotypes with H. Pylori infection were analyzed.
 RESULTS: The frequencies of -11391G/A (AA) and EC-SOD (CG+GG) were 50.67% and 50.33% in NAFLD cases, 23.83% and 24.17% in healthy controls, respectively. Statistical tests showed significantly higher frequencies of -11391G/A (AA) and EC-SOD (CG+GG) in the NAFLD group (-11391G/A: P=0.0051; EC-SOD: P=0.0057). The risk of NAFLD with -11391G/A (AA) was significantly higher than those with -11391G/A(GG+GA) (OR=3.2822, 95% CI 1.9170 to 5.2039). The individuals who carried EC-SOD (CG+GG) had a high risk of NAFLD (OR=3.1800, 95% CI 1.7974 to 5.2391). Combined analysis of the polymorphisms showed that percentage of -11391G/A (AA)/EC-SOD (CG+GG) in the NAFLD group was significantly higher than that in the control groups (25.50% vs 5.83%, P=0.0039). The people who carried with -11391G/A (AA)/EC-SOD (CG+GG) had a high risk of NAFLD (OR=10.3190, 95% CI 8.1869 to 20.5102). The H. Pylori infection rate in the NAFLD group was significantly higher than that in the control group (OR=3.1667, 95% CI 1.9139 to 5.7443, P=0.0062), and statistical analysis suggested a positive correlation between H. Pylori infection and NAFLD with -11391G/A (AA) and EC-SOD (CG+GG) (-11391G/A: γ=1.8532; EC-SOD: γ=1.7899).
 CONCLUSION These carriers of -11391G/A(AA) and EC-SOD (CG+GG) genotypes may have a high risk of NAFLD, and the gene genotypes can interact with H. Pylori infection in the pathogenesis of NAFLD. Therefore, effective prevention measures for NAFLD should consider eradicating H. Pylori or regulating gene expression.

OBJECTIVE: To investigate the interaction between polymorphism of Toll-like receptor 4 (TLR4) gene G11367C in 3' untranslated region (UTR) and inhibitor of nuclear factor kappaB (IκB)-α 
Hae III in acute pancreatitis (AP) and the degree of severity.
 METHODS: A total of 450 patients with confirmed AP (AP group), who came from the First Affiliated Hospital of Xinxiang Medical College from May 2013 to June 2015, were divided into a mild AP subgroup (MAP subgroup), a moderately severe AP (MSAP subgroup), and a severe acute AP (SAP subgroup) (n=150 in each group). One hundred fifty healthy persons were served as a control group. There was no significant difference in age, gender, ethnicity and birthplace among all groups. The genetic polymorphisms of TLR4 gene G11367C in 3' untranslated region and IκB-α Hae III were analyzed by polymerase chain reaction (PCR). Eligible participants were personally interviewed by a questionnaire. Unconditional logistic regression model and single factor analysis were performed to calculate the adjusted odds ratios (OR) and 95% confidence intervals (95% CI) of G11367C and IκB-α Hae III polymorphisms, respectively. The interaction of nucleotide polymorphisms was analyzed.
 RESULTS: The frequencies of G11367C (GC), IκB-α Hae III (AG) and IκB-α Hae III (GG) were 69.56%, 33.78% and 36.22% in the AP group; 49.33%, 24.67% and 26.00% in the MAP subgroup; 70.67%, 34.67% and 36.67% in the MSAP subgroup; 88.67%, 42.00% and 46.00% in the SAP subgroup and 26.67%, 14.00% and 14.67% in the control group, respectively. There was significant difference in the frequencies betweenc the AP group and the control group, or among each AP subgroup (all P<0.01). The risk of AP was significantly increased in the subjects with G11367C (GC) genotype (ORAP=6.2828, ORMAP=2.6776, ORMSAP=6.6250, ORSAP=21.5147), which was also increased in those with IκB-α Hae III (AG) genotype (ORAP=5.7369, ORMAP=2.5277, ORMSAP=6.1824, ORSAP=17.8572) and in those with IκB-α Hae III (GG) genotype (ORAP=5.8724, ORMAP=2.5902, ORMSAP=6.4027, ORSAP=18.9022). The combined analysis of the polymorphisms showed that the percentage of G11367C (GC)/ IκB-α Hae III (GG) in the AP group, the MAP subgroup, the MSAP subgroup, the SAP subgroup and the control groups was 26.44%, 12.67%, 26.00%, 40.67% and 4.00%, respectively, with significant difference in the frequency among all groups (all P<0.01). The people who carried with Pro12Ala (AA)/Pro198Leu (LL) had a high risk of AP (ORAP=30.1314, ORMAP=6.7612, ORMSAP=39.5000, ORSAP=401.5833), and the statistical analysis suggested a positive interaction between Pro12Ala (AA) and Pro198Leu (LL) in increasing the risk of AP (All γ>1). Similarly, there were also positive interactions in the pathogenesis of AP between G11367C (GC) and IκB-α Hae III (AG) (All γ>1). 
 CONCLUSION These carriers of G11367C(GC), IκB-α Hae III(AG) and IκB-α Hae III (GG) genotypes may have a high risk of AP occurency, and there are significant interactions between genetic polymorphisms of G11367C and IκB-α Hae III, which increaes the risk of the occurrence and development of AP.

OBJECTIVE: To investigate the expression and localization of metabotropic glutamate receptors 7 and 8 (mGluR7/8) in rat superior cervical ganglion (SCG) and their changes in response to chronic intermittent hypoxia (CIH). METHODS: We detected the expressions of mGluR7 and mGluR8 in the SCG of 8-week-old male SD rats using immunohistochemistry and characterized their distribution with immunofluorescence staining. The expression of mGluR7 and mGluR8 in the cytoplasm and nucleus was detected using Western blotting. A 6-week CIH rat model was established by exposure to intermittent hypoxia (6% oxygen for 30 s followed by normoxia for 4 min) for 8 h daily, and the changes in systolic blood pressure, diastolic blood pressure and mean arterial pressure were measured. The effect of CIH on expression levels of mGluR7 and mGluR8 in the SCG was analyzed using Western blotting. RESULTS: Positive expressions of mGluR7 and mGluR8 were detected in rat SCG. mGluR7 was distributed in the neurons and small fluorescent (SIF) cells with positive staining in both the cytoplasm and nuclei, but not expressed in satellite glial cells (SGCs), nerve fibers or blood vessels; mGluR8 was localized in the cytoplasm of neurons and SIF cells, but not expressed in SGCs, nerve fibers, or blood vessels. Western blotting of the nuclear and cytoplasmic fractions of rat SCG further confirmed that mGluR7 was expressed in both the cytoplasm and the nucleus, while mGluR8 exists only in the cytoplasm. Exposure to CIH significantly increased systolic blood pressure, diastolic blood pressure and mean arterial pressure of the rats (all P < 0.001) and augmented the protein expressions of mGluR7 and mGluR8 in the SCG (P < 0.05). CONCLUSION mGluR7 and mGluR8 are present in rat SCG but with different localization patterns. CIH increases blood pressure of rats and enhanced protein expressions of mGluR7 and mGluR8 in rat SCG.

OBJECTIVETo explore clinical short and long-term effect of combining dalitong granule (DG) and electroacupuncture group (EA) in the treatment of functional dyspepsia.

METHODSTotally 640 patients with confirmed functional dyspepsia were randomly divided into 4 groups using a randomized digital table: the DG group, the EA group, the combined group and the control group, 160 cases in each group. The DG group was treated with 6 g DG 3 times daily; the EA group was treated with puncture of points Zusanli (ST36), Zhongwan (CV12), Neiguan (PC6), Taichong (LR3) and Gongsun (SP4) twice daily; the combined group with above-mentioned DG and EA; and the control group with 5 mg mosapride 3 times, 20 mg pantoprazole and 25 mg amitriptylines twice daily. The treatment course was 4 weeks for all groups. The symptom score, quality of life score by Short Form 36 Health Survey Questionnaires (SF-36), plasma motilin by radioimmunoassay, electrogastrographic frequencies by electrogastrogram (EGG) and gastric emptying by B-sonography were examined, and adverse reactions were observed before, at the end of treatment and 60 weeks post-treatment.

RESULTSIn the DG group 1 case dropped out for not taking medicine strictly and 1 case was lost to follow-up, while 1 case in the EA group and 2 cases in the combined therapy group were lost to follow-up. Compared with pre-treatment, quality of life score, plasma motilin, electrogastrographic frequencies and gastric emptying were all increased significantly, while symptom score was decreased significantly at the end of treatment in each group (P<0.01); in the combined group quality of life score, plasma motilin, electrogastrographic frequencies and gastric emptying were all significantly higher than those in the other groups, while symptom score was significantly lower than in the other groups (P<0.05). Compared with at the end of treatment, these indices changed insignificantly in the combined group and the EA group 60 weeks post-treatment (P>0.05), but the 4 increased indices were all decreased significantly, and symptom score was increased significantly in the DG and the control groups (P>0.05). The short and long-term total effective rates in the combined group were all significantly higher than those in the other treatment groups (P<0.05 or P<0.01). No serious adverse reaction occurred in the four groups.

CONCLUSIONCombined treatment of DG and EA could increase both plasma motilin and electrogastrographic frequencies, promote gastric emptying, alleviate the symptom of dyspepsia so as to increase quality of life, with better safety and long-term effect.

OBJECTIVE: To explore the exact mechanisms of programmed cell death (PCD) induced by Type II anti-CD20 mAb in CD20+ non-Hodgkin lymphoma (NHL) cells, and to provide theoretical basis for anti-tumor ability of new CD20 mAb.
 METHODS: After incubation with Rituximab (a Type I anti-CD20 mAb) and Tositumomab (a Type II anti-CD20 mAb), Raji cells were stained by annexin V & propidium iodide (PI). The ratio of programmed death cells were measured by two channel flow cytometry (FCM). Before the treatment of anti-CD20 mAbs, Raji cells was incubated with a caspase inhibitor carbobenzoxy-valyl-alanyl-aspartyl-[O-methyl]- fluoromethylketone (Z-VAD-FMK) and a dihydroceramide synthase inhibitor fumonisin B1 (FB1) for 30 minutes to assess their inhibitory effect on PCD. High performance liquid chromatography (HPLC) was utilized to compare the ratio of programmed death cells between the pretreatment group (treated by Rituximab and Tositumomab) and the non-pretreatment group. The anti-CD20 mAbs-treated Raji cells were collected, and the ceramide levels in the Raji cells in the different pretreatment groups were also examined by HPLC, and the inhibitory effect of FB1 on the changes of ceramide levels in the Raji cells was measured. The Raji cells were incubated with different concentration C2-ceramide, C2-Ceramide-induced PCD was also evaluated by annexin V & PI staining after 16 hours. 
 RESULTS: Tositumomab (10 µg/mL) but not Rituximab (10 µg/mL) can induce significant PCD (28.6±4.2)% in Raji cells, with significant difference (t=26.48, P<0.01), which cannot be blocked by Z-VAD-FMK with a concentration range from 10 to 30 µmol/L (F=3.01, P>0.05). The cellular ceramide levels in Raji cells were significantly elevated after the treatment of Tositumomab (t=28.48, P<0.01). C2-ceramide can significantly induce PCD in Raji cells in a dose-dependent manner with a concentration range from 5 to 40 µmol/L (F=2.71, P>0.05). The dihydroceramide synthase inhibitor FB1 can significantly inhibit the elevated cellular ceramide levels (F=20.18, P<0.01) and cell programmed death induced by Tositumomab (F=17.02, P<0.01).
 CONCLUSION Type II but not Type I anti-CD20 mAbs can induce caspase independent PCD in CD20+ NHL cells through the elevation of cellular ceramide levels. The PCD is not associated with classic caspase pathway.
