Objective To investigate the acute phase adverse effects and influencing factors of adverse effects of diphosphonate treatment in the elderly patients with primary osteoporosis.Methods A total of 208 patients [male 25 patients,female 183 patients,age 60 ～ 93 with a average of (75.51 ± 7.73) years] with primary osteoporosis were selected from 1 Jan 2012 to 30 Nov 2015,admitted to Department of Geriatrics.According to the serious condition of osteoporosis and willingness of patients,208 patients were divided into zoledronic acid treatment group,alendronate treatment group,and pamidronic acid group,and received corresponding diphosphonate treatment.All kinds of adverse reactions of diphosphonate in each treatment group were closely to be observed after administration of diphosphonate in 3 days and 7 days.Results The incidence rate of adverse reactions in the zoledronic acid treatment group (59/134,44.03％;60/134,44.78％) was obviously higher than that in the alendronate treatment group (1/57,1.75％;1/57,1.75％),and the pamidronic acid group (3/17,17.65％;3/17,17.65％) after treatment of diphosphonate in three and seven days (P ＜ 0.05).In different generations,the incidence rate of adverse reactions in the zoledronic acid group and the pamidronic acid group after treatment of diphosphonate in three and seven days was not statistically significant (P ＞ 0.05).There were three patients suffering from severe acute kidney injure (AKI) and three patients suffering from hypokalemia in the 134 patients treatment with zoledronic acid.Conclusions There are obvious differences in the incidence rate of acute phase adverse reactions in the osteoporosis patients who received different treatment policy (P ＜ 0.05).The safety issues in the kidney function and electrolyte abnormality (such as hypokalemia) should be paid much enough attention in the primary osteoporosis patients who receive zoledronic acid treatment.

Objective To understand the use of antiplatelet drugs in patients with coronary heart disease( CHD) ,and to compare the effect of different anti platelet drugs on cardiovascular events in patients with CHD,and to provide clinical evidence for the optimization of anti platelet therapy?Methods One thousand and twenty?three cases patients with CHD who were treated in the First Hospital Affiliated to Chongqing Medical University from April 2010 to June 2014 were chosen?On the basis of conventional treatment,according to the different anti platelet program,the patents were divided into A group(703 cases),B group(211 cases) and C group(109 cases)?Group A was treated with aspirin and clopidogrel,B group was treated with clopidogrel,and C group was given aspirin therapy?Cardiovascular events( MACE) and bleeding events were observed at 1 month,6 months and 1 year after treatment in the 3 groups?Results After treatment for 1 month,6 months and 1 year,the incidence rates of MACE in group A were 9?1%( 64/703) ,16?6%( 117/703) and 28?4%( 200/703) ,in group B were 14?6%(31/211),25?5%(54/211) and 37?9%(80/211),in group C were 16?5%(18/109),29?4%( 32/109) and 34?0%( 37/109)?After treatment for 1 month,6 months and 1 year,the incidence rates of MACE in group A was significantly lower than group B and C(P<0?05);after treatment for 1 month,6 months,the incidence rates of MACE in group B were lower than group C,while higher than group C after 1 year,but the differences were not signifiacnt( P>0?05)?There were no significant differences in total incidence of deaths,the recurrence rate of myocardial infarction and stent restenosis rate among the three groups ( P>0?05 )?After treatment for 1 month,6 months,the incidence of angina in group A was lower significantly than that in group B and C( P<0?05) ,but When the treatment time was extended to 1 year,there was no significant difference in the three groups(P>0?05)?At 1 year follow?up,the incidence of gastrointestinal bleeding in group A was slightly higher than that in group B and group C ( 4?3% vs? 2?4% vs?3?7%) , but the difference was not statistically significant ( P>0?05 )?Conclusion In the CHD patients receiving aspirin and clopidogrel dual antiplatelet therapy,the incidence of MACE was lower than that in patients with aspirin or clopidogrel treatment alone, especially a reduction in the incidence of angina,and without increase of the risks in the gastrointestinal bleeding events,but the advantages above waning with treatment time extended to 1 year.

OBJECTIVETo investigate whether the cardioprotective effect of hemin against ischemia/reperfusion (I/R) injury is through the inhibition of calpain activity, and to explore its underlying mechanism.

METHODSSixty-four SD rats were randomly divided into eight groups (n = 8): sham, I/R, MDL+ I/R, MDL, hemin + I/R, hemin, and ZnPP + hemin+ I/R, ZnPP. Iangendorff isolated rat heart perfusion model was used. The rat hearts were suffered from 40 min of ischemia followed by 30 min of reperfusion. After that, left ventricular developed pressure (LVDP) was recorded. Infarct size and release of lactate dehydrogenase (LDH) were measured. Calpain, heme oxygenase (HO), and caspase 3 activities were evaluated. Expression of calpastatin protein was detected by Western blot.

RESULTS(1) After suffered from ischemia/reperfusion, the calpain activity and caspase 3 activity increased. MDL28170, an inhibitor of calpain, prevented ischemia/reperfusion induced increases in LDH and infarct size, improved the LVDP recovery. (2) Compared with ischema/reperfusion rat hearts, pretreatment of hemin enhanced the HO-1 activity, decreased the calpain and caspase 3 activities, declined LDH release and infarct size, and improved LVDP recovery. (3) Ischemia/reperfusion reduced the expression of calpastatin protein in rat hearts, which was inhibited by hemin pretreatment. And HO-1 inhibitor could abolish the cardioprotection of hemin.

CONCLUSIONCardioprotective effect of hemin against ischemia/reperfusion injury is through the inhibition of calpain activity, the mechanism might be involved in the increase in calpastatin protein expression.

Objective To discuss the effects of multimodal combination dialysis on Klotho protein, fibroblast growth factor-23 (FGF-23) and brain natriuretic peptide (BNP) in patients with maintenance hemodialysis (MHD). Methods A randomized controlled trial (RCT) was conducted. 120 patients who was diagnosed with chronic renal failure (CRF) uremia receiving MHD over 3 months admitted to Blood Purification Centre of Department of Nephrology of the Second People's Hospital of Guiyang from December 2015 to December 2016 were enrolled, who were randomly divided into hemodialysis (HD) group (HD for 8 times a month), HD + hemofiltration (HF) group (HD for 8 times a month + HF once a month), and HD + HF + hemoperfusion (HP) group (HD for 8 times a month + HF for 4 times a month + HP once a month), with 40 patients in each group. Before and after treatment for 6 months and 12 months, blood was taken from venous circuit tube, the serum Klotho protein and FGF-23 levels were determined by enzyme linked immunosorbent assay (ELISA), and the serum BNP level was determined by electrochemiluminescence. Results 120 patients with MHD were enrolled in the final analysis without withdrawal. There were no significant differences in the levels of Klotho protein, FGF-23, or BNP before enrollment among the three groups (all P > 0.05). Compared with those before enrollment, the levels of serum Klotho protein after enrollment in three groups showed a sustained upward tendency, which were higher in HD + HF + HP group than in HD + HF group and HD group (μg/L: 2.59±0.61, 1.63±0.35, 1.13±0.26 at 6 months, F = 119.374, P = 0.000; 6.98±1.21, 3.57±1.03, 2.12±0.43 at 12 months, F = 275.675, P = 0.000); the levels of FGF-23 showed a sustained downward tendency, which were lower in HD + HF + HP group than in HD + HF group and HD group (ng/L: 69.22±38.26, 132.28±61.18, 178.50±74.64 at 6 months, F = 33.509, P = 0.000; 32.81±17.32, 87.93±43.27, 146.33±69.28 at 12 months, F = 55.466, P = 0.000);the BNP showed a similar tendency as FGF-23 (ng/L: 4083.39±2864.53, 7245.69±4643.81, 7969.12±5360.85 at 6 months, F = 8.758, P = 0.000; 1521.86±894.63, 4554.32±1969.84, 5013.89±2033.64 at 12 months, F = 49.003, P = 0.000). Conclusion Multimodal combination dialysis can increase the Klotho protein level, and decrease the levels of FGF-23 and BNP in MHD patients with CRF uremia.

Objective: To unveil the efficacy of Shaolin internal qigong exercise in treating capsulitis of the shoulder (CS) and explore objective outcome measures by observing the changes in the surface electromyography (sEMG) signals of shoulder muscle groups after regular practice of Shaolin internal qigong exercise in CS patients. Methods: Sixty CS patients were randomized into two groups by the random number table method, with 30 cases in each group. Patients in the qigong group practiced Shaolin internal qigong exercise on a regular basis, while patients in the electroacupuncture (EA) group received EA treatment. Before and after treatment, the sEMG signals of six muscles, i.e. biceps brachii, triceps brachii, deltoid, pectoralis major, latissimus dorsi and trapezius muscles, of the affected side were recorded at 45° abduction of the shoulder, 60° forward flexion and 90° internal rotation with the elbow flexed during maximal isometric contraction, and the integrated electromyography (iEMG) of each muscle was calculated. Results: The total effective rate was 93.3％ in the qigong group, higher than 83.3％ in the EA group (P<0.05). Intra-group comparison showed that the iEMG of biceps brachii, triceps brachii, pectoralis major and deltoid muscles in the qigong group increased significantly after intervention at 45° abduction of the shoulder, 60° forward flexion and 90° internal rotation with the elbow flexed (all P<0.05), and the iEMG of trapezius and latissimus dorsi muscles decreased (both P<0.05); in the EA group, the iEMG of biceps brachii, pectoralis major and deltoid muscles increased significantly during contraction (all P<0.05), while the iEMG of triceps brachii, trapezius and latissimus dorsi muscles had no significant changes (all P>0.05). After intervention, there were significant differences in the iEMG of most of muscles between the two groups (all P<0.05), except for the iEMG of deltoid muscle at 45° of abduction of the shoulder joint during isometric contraction (P>0.05). Conclusion: Shaolin internal qigong exercise can effectively increase the motion intensity of the biceps brachii, triceps brachii, pectoralis major and deltoid muscles and reduce the compensation of the latissimus dorsi and trapezius muscles in CS patients; compared with EA, it produces a better result in improving the coordination and stability in shoulder joint movements.

OBJECTIVEIt has been proposed that aberrant immunity of local bowel mucosa may cause ulcerative colitis (UC) and the tumor necrosis factor-alpha (TNF-alpha) and nuclear factor-kappa B (NF-kappa B) may play a role in the development of this disease. To investigate the role of TNF-alpha and NF-kappa B in childhood UC, the expression of TNF-alpha and NF-kappa B in the bowel mucosa and their relationship were studied.

METHODSUsing anti-CD68, anti-TNF-alpha and anti-NF-kappa Bp65 antibodies, the cytokine immunoreactivities in the bowel mucosa of 39 cases of childhood UC (active UC: n = 21, non-active UC: n = 18) were detected by immunohistochemistry. The control specimens of normal bowel mucosa were collected from 7 cases with colorectal polyp or abdominal pain by sigmoidoscopy.

RESULTSThe numbers (median: interquartile range) of CD68(+) cells, TNF-alpha(+) cells and NF-kappa Bp65(+) cells were 44.0 (31.5 - 48.2), 42.7 (19.5 - 65.0) and 50.7 (30.0 - 58.0) in the active UC mucosa, and were 9.2 (7.9 - 16.6), 5.5 (2.5 - 9.1) and 4.2 (3.0 - 8.4) in non-active UC mucosa, and 5.3 (4.3 - 8.7), 3.0 (0.0 - 6.3) and 3.3 (0.0 - 4.0) in the control mucosa, respectively. The levels of CD68, TNF-alpha and NF-kappa Bp65 expressions in the active UC were significantly higher than those in the non-active UC (P < 0.001) and the controls (P < 0.001). The expression level of CD68 in non-active UC was much higher than that in the controls (P = 0.008). Using the correlation analysis, a positive correlation between TNF-alpha and NF-kappa B activation was found (r = 0.885, P < 0.001).

CONCLUSIONSMacrophages TNF-alpha and NF-kappa B may play an important role in the pathophysiologic mechanism of childhood active UC. The activation of NF-kappa B may be associated with the release of TNF-alpha.

OBJECTIVEDuodenal salami ulcer is a common disease found on routine endoscopic examination in children. The purpose of the study was to explore the characteristics and the clinicopathological features of duodenal salami ulcer in children and to deepen the understanding of duodenal salami ulcer.

METHODSThe endoscopic results of 117 cases with the duodenal salami ulcer were analyzed. The specimens of gastric antrum and duodenal bulb were subjected to HE and Giemsa staining and were examined for any alteration in histopathology and infection with Helicobacter pylori (Hp). The duodenal mucosa was stained with AB (pH 2.5)/PAS in order to diagnose the duodenal metaplasia.

RESULTSThe major endoscopic finding was a kind of hoarfrost, which was dotty or flaky, covered on the hyperemic and edematous mucosa. The detection rate of this change was 2.29% (117/5 106) of all the endoscopic examinations in children and the rate among cases with duodenal ulcer was 49.2% (117/238). The histopathology was characterized by a heavy infiltration of mainly lymphocytes, plasmocytes and neutrophilic granulocytes, frequently accompanied by superficial erosion. Sixty-one cases were pathologically diagnosed as chronic active duodenitis, superficial erosion in 45; chronic duodenitis in 50; eosinophilic duodenitis in 6. Detection rate of Hp in gastric antrum was 58% (68/117) of all cases. Detection rate of Hp infection and gastric epithelium metaplasia in duodenal bulb was 11.1% (13/117) and 31.1% (37/117), respectively. However, detection rate of Hp in gastric antrum was 25.0% (1 203/4 810) in 4 810 cases of normal duodenal bulb and chronic duodenitis in the same period. Detection rate of Hp in duodenal bulb was 0% and the detection rate of gastric epithelium metaplasia in duodenal bulb was 2.7% (128/4 810). All these detection rates were much higher than those of the specimens collected during the same period with normal duodenal bulb and chronic duodenitis (P < 0.001). Twenty-one cases were reexamined by endoscopy after having been treated with antacids or antacids and antimicrobial agents for 4 weeks. The lesions were healed up and no scars were found.

CONCLUSIONDuodenal salami ulcer in children had a special manifestation of duodenal inflammation or erosion but not a real ulcer. It was caused by the Hp infection in gastric antrum or duodenal bulb and the increase of gastric acids. The therapeutic principles were antacid and antimicrobial agents. The prognosis was good.

Objective To investigate the effect of Shenfu injection on the expressions of matrix metalloproteinase-9 (MMP-9) and tissue inhibitors of metalloproteinase-1 (TIMP-1) in rats after cerebral ischemia-reperfusion injury,and explore the brain protection mechanism of Shenfu injection. Methods Ninety adult healthy male Wister rats were chosen and randomly divided into sham-operated group,Shenfu injection treatment group and vehicle group (n=30); animal models of middle cerebral artery occlusion/reperfusion in the later 2 groups were established by a filament method in the left external-internal carotid artery.Rats in the Shenfu injection treatment group were injected with 8 mg/kg Shenfu injection during the reperfusion while those in the vehicle group with physiological saline.These rats in each group were divided into 3 sub-groups (n=10) according to the ischemia time (0.5,1 and 1.5 h after the model establishment). Twenty-four h after reperfusion, dry-weight method was employed to detect the content of brain tissues on the side received ischemia-reperfusion; and Western blotting was employed to observe the expressions of MMP-9 and TIMP-1 in the brain tissues. Results The water content of those brain tissues and the expressions of MMP-9 and TIMP-1 in the Shenfu injection treatment group and vehicle group at each time point significantly increased as compared with those in the sham-operated group (P＜0.05); the longer the ischemic time,the heavier the water content of the brain tissues and the higher the expressions of MMP-9 and TIMP-1. As compared with those in the vehicle group, the water content of the brain tissues and the expression of MMP-9 in the Shenfu injection treatment group obviously decreased,while the expression of TIMP-1 in the Shenfu injection treatment group significantly increased at each time point (P＜0.05). Conclusion Shenfu injection has the function against cerebral edema by accommodating the expressions of MMP-9 and TIMP-1.
