ObjectiveTo observe the clinical efficacy of bee-sting therapy in treating chronic colitis.MethodTotally 101 patients with chronic colitis were randomized into two groups, 39 cases in the control group and 62 cases in the treatment group.The treatment group was intervened by bee-sting therapy, while the control group was by medication. During the intervention, patients in the two groups were asked to keep bland diet and take more food rich in fiber instead of spicy and stimulating food. Abdominal pain, defecation pattern and frequency were observed during the study, and the clinical efficacies were compared a month later.Result The markedly effective rate was 82.3% in the treatment group versus 61.5% in the control group, and the therapeutic efficacyof the treatment group was significantly higher than that of the control group (P<0.05), and the improvements of pain relief and defecation occurred earlier in the treatment group than in the control group.ConclusionBee-sting therapy has advantages of faster pain relief and long-standing therapeutic efficacy.

ObjectiveTo investigate the factors influencing early treatment of patients with acute stroke.Methods300 patients with acute stroke were investigated with questionnaire which including 28 factors influencing patients receiving early treatment.Results41.5% of patients were admitted within 6 hours after onset. The responses after onset, the time to the special hospital after stroke, and whether being able to describe symptoms and style of stroke correctly were independent influencing factors. Other factors such as age, sex and stroke severity had not obvious influence to admission delay.ConclusionEffective public health programs and establishment of effective emergent medical service system are measures to minimize the admission delay.

ObjectiveTo investigate the relation between each subtype of cerebral ischemic stroke classified by NEW-TOAST criteria and the levels of blood sugar. MethodsA retrospective study in 624 patients hospitalized with acute cerebral ischemic stroke. All the patients were classified using NEW-TOAST classification standard. Blood glucose in patients with different stroke subtypes was recorded, and analyzed for the incidence of abnormal glucose metabolism in each subtype. The correlation of glucose to blood sugar,blood pressure and blood fat was analyzed using odd ratio (OR) and 95％ confidence intervals (CI).Results(1) Among 624 patients, the most common stroke subtype by NEW-TOAST classificationis atherothrombosis (AT), followed by small arterial occlusion (SAO). One hundred and nineteen patients (19. 1％ ) had diabetes history; another 40 patients(7.5％ ) were newly diagnosed with diabetes in this study; and 71 patients ( 11.4％ ) were found to have glycoregulation abnormality. The incidence of abnormal glycometabolism was high in patients with AT ( 40. 4％ ) and SAO ( 39. 7％ ). ( 2 ) Association analysis between stroke subtypes and blood sugar: x2 =14. 83,P =0. 020, r =0. 152; in SAO patients, OR was 1. 925 (95％ CI 1. 392-2. 664) ; in the patients with AT, there was no correlation to blood sugar levels.Association analysis of high blood pressure in stroke subtypes: in AT patients, OR was 2. 874 (95％ CI 1. 957-4. 222) ; in SAO, OR was 1. 609 (95％ CI 1. 100-1. 235). Association analysis of high LDL-C in each subtype: OR in SAO was 1.419 (95％ CI 1.026-1. 962) ;No significant correlation of LDL-C in AT patients, P =0. 929 ; (3) There is significant difference of frequency of abnormal glycometabolism between stroke subtypes: x2 =17. 79 ,P =0. 000; between AT and SAO patients, x2 =0. 024,P =0. 877; between AT or SAO patients to other three subtypes, P ＜ 0. 05. ConclusionsAmong the subtypes of cerebral ischemic stroke by NEW-TOAST classification, AT and SAO are the most common subtypes.All the subtypes have correlation to the high level of blood sugar, and SAO has the highest correlation to blood sugar levels. High blood pressure may affect both large vessels and small vessels, while high LDL-C may mainly affect small vessels.

Objective To explore the relationship between plasma homocysteine(Hcy) levels and cerebral infarction.Methods 87 patients with acute cerebral infarction and 80 controls were enrolled in the study. Plasma Hcy levels were measured by high-performance liquid chromatography-fluorescence detection(HPLC-FD) technology using Baseling 810 type high-performance liquid chromatograph.Results Fast plasma Hcy levels were higher in the patient group[(15.28?4.33)?mol/L] compared with those in the control group[(11.32?3.86) ?mol/L]( P

Objective To study the relationship of plasma homocysteine (Hcy), polymorphism in 5,10-methylenetetrahydrofolate reductase (MTHFR) and cystathionine-?-synthase (CBS) genes, and cerebral infarction in the elderly. Methods 61 elderly patients with first-ever acute cerebral infarction and 57 controls were studied. The plasma Hcy levels were measured using high-performance liquid chromatography-fluorescence detection (HPLC-FD). The polymorphism in MTHFR was determined by a polymerase chain reaction (PCR) assay and subsequent restriction enzyme digestion.CBS was determined by amplification refractory mutation system (ARMS). Results The fast plasma Hcy levels were higher in the patient group compared with those in the control group [(13.07?3.96)?mol/L vs (11.51?3.90)?mol/L, P 0.05). There were no differences in the plasma Hcy levels among the different genotypes. Conclusions The MTHFR, CBS gene mutations cannot lead to hyperhomocysteinemia in the elderly patients with acute cerebral infarction. Hyperhomocysteinemia is associated with the independent risk of cerebral infarction, however, mutations only in MTHFR and CBS cannot be ascertained to be independent risk of cerebral infarction in the elderly.

ObjectiveTo explore the relationship between plasma homocysteine (Hcy), polymorphism in 5,10-methylenetetrahydrofolate reductase (MTHFR) and cystathionine-β-synthase (CBS), and cerebral thrombosis.Methods87 subjects with first-ever acute cerebral thrombosis and 80 controls were studied. The plasma Hcy levels were measured using high-performance liquid chromatography-fluorescence detection (HPLC-FD). The polymorphism in MTHFR was determined by a polymerase chain reaction (PCR) assay and subsequent restriction enzyme digestion and that in CBS was determined by amplification refractory mutation system (ARMS).ResultsThe fast plasma Hcy level in the patient group was (15.28±4.33)μmol/L significantly higher than that ( 11.32 ±3.86)μmol/L in the control group (P<0.001). Different genotype had different influence on the plasma Hcy levels. There were no differences in genotype frequencies or allele frequencies between the patient group and control group (P>0.05).ConclusionCommon mutations in MTHFR, CBS G919A and CBS T833C lead to hyperhomocysteinemia. Hyperhomocysteinemia, but not common mutations in MTHFR and CBS is associated with the increased incidence of cerebral thrombosis.

Objective To detect the levels of serum uric acid(SUA),lipid and creatinine(SCr) of type 2 diabetes mellitus(T2DM),and discuss the correlation between them and diabetic nephropathy(DN).Methods One hundred and two cases of T2DM patients were selected and divided into three groups based on the level of urine microalbumin(mAlb)/creatinine(Cr):30 cases of N-UAlb group(urine mAlb/Cr＜30μg/mg),41 cases of M-UAlb group(30μg/mg≤urine mAlb/Cr＜300μg/mg)and 31 cases of C-UAlb group(urine mAlb/Cr≥300 μg/mg),detected the SUA,SCr,HbA1c,fasting insulin(FINS),triglyeride(TG)and calculated the creatinine clearance rate(CCr).Selected 40 healthy subjects as control group.Results The SUA level in C-UAlb group[(369.3±181.2)μmol/L]was significantly higher than the other groups [(248.6±109.4)μmol/L in control group;(228.7±104.8)μmol/L in N-UAlb group;(296.5±121.4)μmol/L in M-UAIb group](P＜0.01 or＜0.05),and increased with increment of urine mAlb/Cr.In the whole study population,the Pearson correlation coefficient of SCr,CCr,TG and SUA were 0.369,-0.389.0.525,respectively(P＜0.01).Multiple regression analysis showed that SUA levels in T2DM patients were positively correlated with TG(P＜0.05),and were negatively correlated with CCr(P＜0.05).Conclusions TG and CCr are independent risk factors of SUA.CCr correlates with SUA better than SCr.Diabetic hyperuricemia might affect the process of occurrence and development of DN.There is need for prevention and treatment.
