Objective To investigate the intelligence standard for diagnose the sub-cretin children and children with mental retardation of socio-cultural type.Methods The full intelligence quotient(IQ),verbal intelligence quotient(VIQ)and performance intelligence quotient(PIQ)was tested by Wechsler scale(C-WISC)for mild iodine deficiency disordem children,children living in abnormal socio-cultural condition and normal children aged 7～14 years old in Qinba mountain area.The test results had been compared between the groups.Results There were no significant difference between psychomotor functioning well children and children living normal sociocuhural condition in VIQ,PIQ and full IQ(89.24±18.44 vs 90.75±17.58,87.58±15.78 vs 88.95±15.56,87.42±17.84 vs 89.02±17.18,t=1.14,1.19 and 1.24,respectively,all P＞O.05).PIQ and full IQ were significantly lower in mild iodine deficiency disorders children than in children with abnormal socio-cultural background (65.81±10.22 vs 72.33±13.23,62.42±12.31 vs 68.13±14.54,t=3.26,2.55,P＜0.01 or＜0.05,respectively).But the VIQ was not significantly different between these two groups.The average difference of VIQ and PIQ among mild iodine deficiency disorders children wag-0.32 without significant difierence(t=0.28,P＞0.05),however it was-2.91 among children under abnormal socio-cultural condition with significant difierenee(t=-3.59,P＜0.01).Conclusions IQ for iodine deficiency disorders children is characterized by that VIQ is damaged in parallel with PIQ,while that in children under abnormal soeio-cuhural condition is marked by that VIQ is retarded more severely than PIQ,which ean be used as an intelligence standard for differentiating the sub-cretin children from children wjth socio-cuhural mental retardation.

OBJECTIVETo explore the cardiac protective effect of integrative therapy in acute myocardial infarction (AMI) with elevated ST segment after reperfusion.

METHODSSixty-four AMI patients who having received decimalization by thrombolysis were assigned to two groups by retrospective analysis, 36 patients in the treated group and 28 in the control group. Both were treated by intravenous administering of urokinase for thrombolysis, and to the treated group, intravenous dripping of Xueshuantong Injection (, XST) was added. Serum levels of myocardial associated enzymes were monitored before treatment and at various time points after thrombolysis, and the heart function parameters were detected with color echocardiography before treatment and on the 7th and 14th day of treatment. The patients were followed up for 6 months to observe the incidence of cardiac events.

RESULTSThe differences between groups at the peak and peak appearing time of creatine kinase and creatine kinase isoenzyme were not significant. All the heart function parameters on the 7th and 14th day in the treated group were improved and superior to those at the corresponding time points in the control group (P<0.05, P<0.01). Incidence of some heart events in the treated group within the 6-month follow-up period was lesser than that in the control group (P<0.05).

CONCLUSIONXST Injection could provide effective protection for the heart after reperfusion.

OBJECTIVE To study the relationship between TCM syndrome types and clinical biochemical indexes in type 2 diabetes mellitus,and to an objective basis for TCM syndrome differentiation of type 2 diabetes mellitus.METHODS 120 type 2 diabetes mellitus patients corresponding to the study criteria were collected.Syndrome differentiation was made for these pa-tients according to yin deficiency and heat excess,spleen deficiency,phlegm accumulation,deficiency of both Qi and Yin and qi deficiency and blood stasis.At the same time,40 healthy subjects were matched as controls.The relationships between differ-ent types and age,body mass index(BMI),glucose metabolism,lipid metabolism,hypersensitivity C reactive protein(hs-CRP),insulin resistance indexes(HOMA-IR)and serum insulin(FINS)were analyzed.RESULTS ①Compared with the normal control group,BMI in the yin deficiency and heat excess group decreased significantly(P<0.01),BMI in the spleen deficiency and phlegm accumulation group increased significantly(P<0.01).②Compared with the normal control group,all indexes of TC,TG and LDL in the diabetes mellitus group increased(P<0.05),HDL index decreased(P<0.05).③All FPG,HOMA-IR,HbA1c and hs-CRP levels in the diabetes mellitus group increased compared with the normal control group(P<0.05～0.01).Apart for the yin deficiency and heat excess group,FINS indexes in the rest three group had significant differences compared with the normal control group(P<0.05).CONCLUSION There are correlations between various TCM syndromes of type 2 diabetes mellitus and lipid metabolism,glucose metabolism,body mass index and insulin resistance index.The study of the relationship between them will contribute to the objectification of TCM syndrome differentiation in diabetes mellitus.

OBJECTIVETo evaluate the results of the surgical treatment of patients with Budd-Chiari syndrome (BCS).

METHODSThe clinic data of 120 BCS patients who underwent various consecutive surgical treatments from July 2001 to October 2010 was analyzed. There were 82 male and 38 female patients, aging from 11 to 72 years with a mean age of (41 ± 13) years. All patients experienced various examinations to identify the pathological type of BCS. There were 5 cases of small hepatic veins type, 28 cases of large hepatic veins (LHV) type, 31 cases of inferior vena cava (IVC) type and 56 cases of combined obstruction of LHV and IVC. Totally, 25 patients experienced interventional treatment, include percutaneous transluminal angioplasty and/or stenting for stenosis of hepatic vein and/or IVC, 77 patients experienced open-thorax operation for BCS radical resection under protection of right atrium by-pass with extracorporeal circulation.

RESULTSTotally 97 cases were followed up from 1 to 120 months after various surgical treatment methods. Perioperative mortality was 6.2% (6/97). Follow-up period mortality was 8.2% (8/97). The restenosis of IVC and/or hepatic vein happened in 3 cases out of 25 cases in intervention treatment group in contrast with 15 cases out of 77 cases in radical resection group. The 5-year patency and survival rate of IVC/hepatic vein were 64.5% and 83.3%.

CONCLUSIONSThe surgical treatment of BCS need to get accurate diagnosis and pathological classification firstly, then, to choose appropriate therapeutic strategies based on individual pathological classification. The BCS radical resection can be an alternative method in some particular pathological classifications and the cases who failed in interventional treatment.

OBJECTIVETo screen effective sequences of small interfering RNA targeting MDR1 gene in human gastric cancer SGC7901/VCR cells.

METHODSFour siRNAs (MDR1si326, MDR1si1513, MDR1si2631 and MDR1si3071) targeting MDR1 gene were designed and synthesized by in vitro transcription. The siRNA duplexes were used to transfect into the human gastric cancer SGC7901/VCR cells. The expression level of MDR1 mRNA and P-gp were detected by RT-PCR and Western blotting, respectively. The accumulation of intracellular adriamycin (ADR) was examined by flow cytometry and the cell sensitivity to ADR was demonstrated by MTT.

RESULTSThe SGC7901/VCR cells treated with 4 siRNAs led to reversal effect on multidrug resistance to different extents. Among the SGC7901/VCR cells treated by siRNAs for 48 h, the expression level of MDR1 mRNA in cells of MDR1si326 or MDR1si2631 group (0.42 +/- 0.07 or 0.49 +/- 0.02) was more decreased than that in cells of MDR1si1513 or MDR1si3071 group (P < 0.05). The accumulation of ADR in cells of MDR1si326 group was the most; in cells of MDR1si2631 group, more; in cells of MDR1si3071 group, lower and in cells of MDR1si1513 group, the lowest (P < 0.05). The relative reversal efficiency of cells of MDR1si2631 group to ADR was the highest and in cells of MDR1si326 group, higher (P < 0.05). There was no significant difference in the relative reversal efficiency between the cells of MDR1si1513 and MDR1si3071 groups (P > 0.05). The expression level of P-gp in cells of MDR1si326 group was the lowest among the SGC7901/VCR cells treated by siRNAs for 72 h.

CONCLUSIONThe MDR1si326 with most, MDR1si2631 with more, MDR1si3071 with less and MDR1si1513 with least reversal effects on MDR1 gene mediated multidrug resistance were found in the human gastric cancer SGC7901/VCR cells.

OBJECTIVESTo investigate the clinical effect of sequential therapeutic intervention Yupei Qisun [compensating for weakness by invigorating Kidney (Shen) and Spleen (Pi) in advance] in Chinese medicine (CM) and hysteroscopic endometrial mechanical stimulation on the treatment of infertile patients with repeated implantation failure (RIF); and to study the differences in patients' endometrial thickness and type on the day of embryo transfer, serum hormone levels on embryo transfer day and clinical pregnancy outcomes.

METHODSIn the clinical study, 168 frozen-thawed embryo transfer (FET) cycles for couples with RIF conforming to the research protocol were randomly divided into three groups: a CM group with 56 cycles (CM combined with FET), a hysteroscopy group with 55 cycles (hysteroscopic endometrial mechanical stimulation), and a control group with 57 cycles (conventional FET). Differences in endometrial thickness on the embryo transfer day, levels of serum estradiol (E2) and progesterone (P) on the embryo transfer day, the E2/P ratio on the embryo transfer day, biochemical and clinical pregnancy rates, implantation rate, abnormal pregnancy rate and other indices were compared among the three groups.

RESULTSEndometrial thickness, E2 and P levels, and the E2/P ratio on embryo transfer day and other factors had no significant differences among groups. The biochemical pregnancy, clinical pregnancy, and implantation rates of the CM and hysteroscopy groups were significantly higher than the control group (P<0.05), and there were no significant differences between these two groups. The abnormal pregnancy rate had no significant difference among the three groups.

CONCLUSIONSSequential therapy of Yupei Qisun could significantly improve the clinical outcomes of rif-fet cycles, being equivalent to hysteroscopic endometrial mechanical stimulation, and provided a reliable method to treat such infertile couples.

OBJECTIVETo investigate the effects of taurine on myocardial mitochondria and their enzyme activities in rats with severe burn.

METHODSOne hundred and twenty healthy adult Wistar rats were subjected to 30% TBSA full-thickness burn. They were randomly divided into burn group (B, with intraperitoneal injection of isotonic saline), treatment group (T, with intraperitoneal injection of taurine, 200 mg/kg),with 60 rats in each group . Ten rats with sham scald were used as control (S group). The myocardial tissue samples in B and T groups were harvested at 1, 3, 6, 12, 24 and 48 postburn hours (PBH) for determination of activity respectively of succinate dehydrogenase (SDH), cytochrome oxidase (CCO), the superoxide dismutase (SOD), Ca2+ -ATPase in mitochondria, and contents of cytochrome c (Cyt c), cytochrome aa3 (Cyt aa3), malondialdehyde (MDA), and Ca2+ in mitochondria and cytoplasm . The myocardial tissue samples of controls were harvested at 1 PBH for determination of above indices.

RESULTSThe activity of CCO in B group was decreased at 1 PBH , especially at 6 ,12 PBH. The activity of SDH in B group was decreased to lowest level at 6 PBH, and its value was lower than that of S group at each time point. The activity of CCO or SDH in T group was not obviously decreased, and the activity of CCO at 3, 6, 12 PBH showed significant difference compared with B group (P < 0.05). The contents of Cyt aa3 and Cyt c in B group at 3, 6, 12, 24 PBH were obviously decreased, which were significantly lower than those in T group (P < 0.05). The activity of SOD in B group at 3, 6, 12 PBH was obviously decreased, the activity of Ca2+ -ATPase at 3, 6, 12 and 24 PBH was decreased to different extent, which was significantly lower than those in T group (P < 0.05). The MDA contents in B and T groups were higher than that in S group at 3-48 PBH ,and it was highest in B group (P < 0.05). The Ca2+ content of mitochondria in B group at 1 PBH was increased (13.7 +/- 1.5), and it was (24.8 +/- 2.6), (29.7 +/- 3.1), (16.3 +/- 1.9) and (13.5 +/- 1.7) at 3, 6, 12, 24 PBH respectively,and they were all higher than that of S group (10.7 +/- 1.6, P < 0.05). The Ca2 contents of cytoplasm in group B at 3 - 24 PBH were also higher than that in S group (P < 0.05). The Ca2+ content of mitochondria in T group at 3, 6, 12, 24 PBH was (16.8 +/- 2.8), (18.7 +/- 1.9), (10.5 +/- 1.8) and (13.3 +/- 1.7)respectively, which were lower than that in B group at every time point.

CONCLUSIONTaurine have protective effect on mitochondria and their enzyme activities in myocardium in rats with severe burn, and it may be attributable to improving the ability of eradicating oxygen free radicals and alleviating Ca2+ overload in the mitochondria.

With the aging and changes in living conditions,the incidence rate and mortality of tumors have been rising rapidly,which has become a hot topic in the medical field.At present,the treatment methods or tumors are also improving day by day,mainly relying on surgical resection.However,the characteristics of fast tumor metastasis and spread,as well as complex growth locations,make the surgical resection method limited.More and more people choose drug targeted therapy for tumors in order to reduce surgical side effects,among which cyclic guanosine monophosphate synthase interferon gene stimulatory factor(cGAS-STING signaling pathway)plays an important role in the occurrence,proliferation,and survival of tumor cells.At present,there are many types of drugs used to treat tumors,but most of them have limited control over tumor spread.In order to study the role of traditional Chinese medicine in tumor treatment and leverage its multi-component,multi target,and multi pathway characteristics,this article comprehensively analyzes and summarizes the treatment of tumors using traditional Chinese medicine based on the cGAS-STING signaling pathway in recent years,in order to further study the mechanism of action of traditional Chinese medicine and its active ingredients in the cGAS-STING signaling pathway,it also provides ideas for clinical research on new drugs.
