Objective To explore the perioperative experiences of congenital heart disease in infants.Methods From Jan.2000 to Aug.2006,109 patients with congenital heart disease were operated in our department,their clinical data were retrospectively collected and analyzed.The patients′ age ranged from 31 days to 3 years old (13.6 months).The body weight ranged from 2.1 to 16 kg (8.6 kg).Ninety-three patients were operated under hypothermic anaesthesia with cardiopulmonary bypass(CPB).Sixteen patients underwent deep thermal and low flow CPB.Ultrafiltration was used in 62 patients.Results There were 8 deaths and the operative mortality was 7.3%,4 cases caused by low output syndromeclos(LOS),3 cases caused by pulmonary hypertension and 1 case caused by lung intection.The morbidity was in 25 cases(22.9%),the main complications were LOS in 6 patients and respiratory complications in 18 patients,hydropericardium in 1 case,respectively.Conclusion To improve the operative and CPB technique,and to improve the skills of the postoperative managements of LOS and respiratory complications are the main points in the success of the cardiac operation in infants.

Functional constipation (FC) is a common functional bowel disorder disease that affects life quality of a large number of people. This study aimed to explore the impact of different intensities of electro-acupuncture (EA) treatment for FC patients. Totally, 111 patients with FC meeting the Rome III criteria were randomly assigned to different intensities of EA groups (low and high intensity of EA groups) and medicine-controlled (MC) group. In EA groups, patients were treated with EA at quchi (LI11) and shangjuxu (ST37) bilaterally for 4 weeks, 5 times/week in the first 2 weeks, and 3 times/week in the last 2 weeks. In MC group, 5 mg mosapride citrate was administered orally 3 times/day for 4 weeks. Spontaneous bowel movement frequency each day was recorded using a constipation diary. Self-rating anxiety scale (SAS) and self-rating depression scale (SDS) were used to assess the patients' psychological state. Cortisol (CORT), substance P (SP), and vasoactive intestinal polypeptide (VIP) were evaluated at baseline and at the end of 4 weeks after treatment. As compared with the baseline, there was statistically significant increase in stool frequency every week (P<0.01), but there was no statistically significant difference among the three groups. As compared with the baseline, after 4 weeks of EA therapy, the scores of SDS and serum levels of CORT were decreased significantly in low intensity of EA group (P<0.01), and the serum levels of SP and VIP were increased significantly (P<0.05); the scores of SAS and SDS and serum levels of CORT were decreased significantly in high intensity of EA group (P<0.05), and the serum levels of SP and VIP were increased significantly (P<0.05); the serum levels of CORT and VIP were increased significantly in MC group (P<0.05). As compared with MC group, after 4 weeks of treatment, the serum levels of SP were signifcicantly increased in low intensity of EA group (P<0.01). Low and high intensities of EA could increase the stool frequency, improve the FC patient's anxiety and depression, reduce the serum levels of CORT, and increase the serum levels of SP and VIP effectively. It is concluded that both low and high intensities of EA are effective for FC patients, but there is no significant difference between the low and high intensities of EA.

OBJECTIVETo systematically assess the efficacy and safety of Rhodiola in treating chronic stable angina pectoris.

METHODSOur group searched the Cochrane library, PubMed, Embase, Chinese biomedical literature database (CBM), VIP database (VIP), Chinese Journal Full-text Database (CNKI) for the literature published in English and Chinese till April 2013. Randomized controlled trials (RCTs) were included on the therapeutic effect of Rhodiola or Rhodiola plus conventional Western medicine in comparison with the conventional Western medicine treatment on stable angina. Data were extracted according the data extraction form. The literature methodological quality was assessed by using the Cochrane handbook, and data analyzed by Rev-Man 5.2 Software for Meta-analysis. The effect indicators of outcomes was expressed by odds ratio (OR) and 95% CI.

RESULTSA total of 7 randomized controlled trials, 662 cases of stable angina pectoris patients met the inclusion criteria and all published in Chinese, without one scientific design and high quality literature. Compared with the conventional Western medicine treatment, combined with oral administration of Rhodiola could improve the efficiency of anti-angina (OR = 2.49, 95% CI: 1.02 - 6.09). Combined with intravenous infusion of Rhodiola could also improve the efficacy of angina pectoris (OR = 4.86, 95% CI: 2.4 - 9.82). Oral administration of Rhodiola couldn't improve ECG efficacy (OR = 1.25, 95% CI: 0.67 - 2.34). Intravenous infusion of Rhodiola could improve the clinical efficacy (OR = 2.94, 95% CI: 1.61 - 5.35). Combined with the conventional treatment, intravenous infusion of Rhodiola could improve the whole blood viscosity (low and high shear rates) and inverse variance (IV) (-1.36 and -0.99, 95% CI: -1.65 - 1.07 and -1.26 - 0.71), but could not reduce serum fibrinogen and D-dimer level. The incidence rate of adverse reactions was higher than that of the conventional treatment combined with Rhodiola (OR = 0.1, 95% CI: 0.02 - 0.51).

CONCLUSIONSOn the basis of routine treatment, Rhodiola could further improve patients' symptoms. Combined with intravenous medication, Rhodiola could increase the ECG improvement rate, and reduce adverse reactions. But the methodological quality of included studies was poor, the number of samples was small, and influence factors such as the intervention period was short. This conclusion needs scientific and rational design in a larger sample, multicenter clinical trial to verify.

OBJECTIVETo evaluate the effects of paroxetine on protein kinase PKA, PKC and CaMKII activities in different brain regions in a rat model of depression.

METHODSThirty-six adult male SD rats were randomized into 6 groups, including one control group (I) and 5 groups of depression model established by forcing the rats to swim for 4 weeks. The 5 depression groups received no treatment (II) or were treated with paroxetine at a single dose (III), for a week (IV), 2 weeks (V) or 4 weeks (VI). The radioactivity of PKA, PKC and CaMKII in the hippocampus and prefrontal cortex was quantitatively measured using a liquid scintillation counter.

RESULTSIn the rat hippocampus, PKA and CaMKII activities were significantly lower in groups II, III, IV, and V than in groups I and VI (P<0.01 or P<0.05), but comparable between groups VI and I (P>0.05). PKC activity was significantly lower in group II than in group I (P<0.01), but showed no significant difference between the paroxetine-treated groups and group I (P>0.05). In the prefrontal cortex, the activity of PKA in groups I, II, III, and IV was similar (P>0.05), but all significantly lower than that in groups V and VI (P<0.01). PKC activity was significantly higher in groups II and III than that in group I and other paroxetine-treated groups (P<0.01), and similar between groups IV and I (P>0.05); groups V and VI had significantly lower PKC activity than group I (P<0.01). Group I had the highest CaMKII activity among the groups (P<0.01).

CONCLUSIONChronic administration of paroxetine can reverse chronic stress-induced inhibition of PKA, PKC and CaMKII activity in rat hippocampus, while the effects of paroxetine on the protein kinases can be more complex in prefrontal cortex.

OBJECTIVETo observe the intervention effect of Leihong Granule (LG) in in-stent restenosis (ISR) after endovascular therapy for lower extremity arterial occlusive diseases (LEAOD).

METHODSRecruited 80 LEAOD patients who successfully underwent endovascular therapy (balloon dilation and stent implantation) were randomly assigned to two groups, the control group and the LG group, 40 in each group. Patients in the control group received basic treatment, while those in the LG group additionally took LG for 3 months. Plasma levels of IL-10, IL-18, CRP, and the intima-media thickness (IMT) of lower extremity artery were observed in the two groups between and after treatment. The rate of stent patency, ABI, intermittent claudication, rest pain, and the incidence of amputation the two groups were recorded and observed in the two groups.

RESULTSIn the control group, serum levels of IL-10, IL-18, CRP, and IMT were significantly higher one month after surgery than before surgery (P < 0.05). There was no significant difference in serum levels of IL-10, IL-18, CRP, or IMT between the two groups before surgery (P > 0.05). These indices were obviously lower in the LG group than in the control group after surgery (P < 0.05). Compared with the control group, the incidence rates of intermittent claudication and the rest pain at 6 months and 12 months after surgery significantly decreased (P < 0.05). The stent patency rate at 6 months and 12 months after surgery, and ABI were significantly higher than those of the control group (P < 0.05). There was no statistical difference in the amputation rate between the two groups (P > 0.05).

CONCLUSIONLG might effectively improve ischemic symptoms of affected limbs possibly through lowering the ISR rate after endovascular therapy for LEAOD through preventing immunosuppressive actions.

OBJECTIVETo evaluate clinical effect and safety of floating needle therapy and duloxetine in treating patients with persistent somatoform pain disorder (PSPD).

METHODSTotally 108 PSPD patients were randomly assigned to the floating needle treatment group, the duloxetine treatment group, and the placebo treatment group, 36 in each group. Patients in the floating needle treatment group received floating needle therapy and placebo. Those in the duloxetine treatment group received duloxetine and simulated floating needle therapy. Those in the placebo treatment group received the placebo and simulated floating needle therapy. All treatment lasted for six weeks. Efficacy and adverse reactions were evaluated using Simple McGill pain scale (SF-MPQ) and Treatment Emergent Symptom Scale (TESS) before treatment and immediately after treatment, as well as at the end of 1st, 2nd, 4th, and 6th week of treatment, respectively. Hamilton Depression Scale (HAMD, 17 items), Hamilton Anxiety Scale (HAMA) were assessed before treatment and at the end of 1st, 2nd, 4th, and 6th week of treatment, respectively. Patients in the floating needle treatment group and the duloxetine treatment group with the total reducing score rate of SF-MPQ in Pain Rating index (PRI) ≥ 50% after 6 weeks' treatment were involved in the follow-up study.

RESULTS(1) Compared with the same group before treatment, SF-MPQ score, HAMD score and HAMA total scores all decreased in all the three groups at the end of 1st, 2nd, 4th, and 6th week of treatment (P < 0.05, P < 0.01). Besides , each item of SF-MPQ significantly decreased immediately after treatment in the floating needle treatment group (P < 0.01). Compared with the placebo treatment group, SF-MPQ, HAMD, and HAMA total score in the floating needle treatment group significantly decreased after 1, 2, 4, and 6 weeks of treatment (P < 0.05, P < 0.01). SF-MPQ score, HAMD score and HAMA total score in the duloxetine treatment group also significantly decreased after 2, 4, and 6 weeks of treatment (P < 0.05, P < 0.01). (2) There were 3 patients (8.3%) who had adverse reactions in the floating needle treatment group, 17 (50.0%) in the duloxetine treatment group, and 7 (21.2%) in the placebo treatment group. Compared with the placebo treatment group, the incidence of adverse reaction increased in the duloxetine treatment group (χ² = 6.04, P < 0.05). Besides, it was higher in the duloxetine treatment group than in the floating needle treatment group (χ² = 14.9, P < 0.05). (3) There were 19 patients in the floating needle treatment group and 17 patients in the duloxetine treatment group involved in the follow-up study. Compared with 6 weeks after treatment, no significant difference was observed at 3 and 6 months after treatment in the score of SF-MPQ, HAMD, and HAMA in the floating needle treatment group and the duloxetine treatment group. No significant difference was observed between the two groups (P > 0.05). There were 5 patients (29.4%) who had adverse reactions in the duloxetine treatment group, and no adverse reactions were observed in the floating needle treatment group. The adverse reaction rate was significantly different between the two groups (χ² = 4.26, P < 0.05).

CONCLUSIONSFloating needle therapy and duloxetine were effective in treatment of patients with PSPD. However, floating needle therapy could relieve pain more rapidly than duloxetine, with obviously less adverse reactions.

Background High myopia can be corrected using laser therapy and intraocular lens(IOL)implantation.IOL implantation is more suitable than laser therapy for high myopia if the patients suffer from thinner cornea.Objective This clinical trail was to assess and compare the visual quality following phakic iris-claw intraocular lens (IOL) and implantable contact lens(ICL) implantation for high myopia.MethodsIris-claw phakic intraocular lens was implanted in 17 eyes of 10 patients with high myopia,and age-,refractive-matched 17 eyes of 9 patients were in implantable contact lens (ICL) implantation group.Uncorrected visual acuity,best correct visual acuity,contrast sensitivity under the 3,6,12 and 18 c/d spatial frequencies,wave-front aberrations,including RMS3,RMS4 and RMSh,were examined in 6 months after operation.Written informed consent was obtained from each patient before surgery.Results There were no significant difference in uncorrected visual acuity,best correct visual acuity between two groups(t=0.489,P>0.05;t=0.853,P>0.05).Non-glare CS under the 3 c/d,6 c/d,12 c/d and 18 c/d spatial frequencies were insignificantly different between two groups ( t = 0. 906, P > 0.05 ; t = 0. 103, P > 0. 05 ; t =0. 694 ,P>0. 05 ; t = 1. 583, P>0. 05), and the similar outcomes were found in glare CS ( t = 0. 323, P>0.05, t =0.041 ,P>0. 05, t = 0.024, P>0. 05; t = 0. 363, P>0.05) in postoperative 6 months. RMS3 and RMSh were significantly elevated in PIOL group compared with ICL group ( t = 11.40, P< 0. 05 ; t = 11.35, P < 0.05), but no evident difference was found in RMS4 between two groups( t = 0. 24,P>0. 05). Conclusion Both PIOL and ICL implantation for high myopia can achieve an equal visual acuity. But clinical outcomes of ICL implantation is much better than PIOL group. A long-term effect should be observed for the further evaluation.

Background Epidemiological surveys showed that the types of bacteria are different in the conjunvical sac from different nationalities,which possibly is associated with living environment.To characterize the types of conjunctival bacteria involved is important for the prevention and treatment of infectious eye diseases.Objective The present survey was to obtain data about bacterial species in the conjunctival sac in the Tibetan minority population aged over 40 years old and compared with the matched Han nationality population.Methods The standardized training and protocol were performed before this survey.A total of 290 eyes of 145 individuals from the Tibetan minority and 346 eyes of 173 subjects from the Han nationality were enrolled in this study in Ganzi Autonomous Prefecture,who had received questionnaire surveys and ophthalmological examinations.The secretion of the inferior palpebral conjunctival sac was embrocated and inoculated and grown on blood plates for 48-72 hours.The bacteria were isolated and identified.This study was approved by the Medical Ethic Committee of the Sichuan People Hospital.Oral informed consent was obtained from the subjects.Results No significant differences were seen in the constituent ratio of the gender as well as the age between the Tibetan minority and Han nationality in this study (x2 =0.987,P=0.3202;t=1.142,P=0.254).There was a significant difference in the proportions of farmers and herdsmen between the two groups(x2 =8.557,P =0.000).The positive rate of bacterial cultivation in Tibetan individuals was 50.74％,showing a statistically significant decrease in comparison with the Han people(60.4％)(x2=6.042,P=0.014).There was no statistical difference in the multiple bacterial species between the two groups (11.0％ in Tibetan,11.6％ in Han people)(x2 =0.0271,P =0.869).The rate of staphylococcus epidemics was 26.6％ in the Tibetan minority and that of Han population was 33.2％,without a significant difference between them (x2 =3.350,P=0.060).No significant difference was seen in the ratio of corynbacterium infection between the two population(15.9％ vs.17.3％)(x2 =0.248,P =0.618).Conclusions The ratio of bacterial cultivation in Tibetans is statistically lower than that of the Han people.The types and distribution of bacteria are similar in the Tibetan and Han nationality.
