Objective To evaluate the feasibility and safety of double-lumen balloon catheter applied in patients with achalasia of cricopharyngeal muscle. Method Fifty patients with achalasia of cricopharyngeal muscle were randomly divided into experimental group and control group. All the patients received routine drug treatment,swallowing function training,feeding training and low frequency VitalStim electric stimulation. In addition,double-lumen balloon catheter and #14 urinary catheters were applied to patients in the experimental group and control group,respectively. The swallow water tests and video fluoroscopy swallowing study(VFSS) were used to evaluate the treatment effects,the electron-nasopharyngolaryngoscope was used to assess bleeding and swelling of mucous membrane,and VRS-5 was used to assess pain. Result After treatment,the scores of swallow water tests and VFSS were significantly better than those before treatment in both groups(P<0.05). There was no significant difference between the two groups(P>0.05). However,the incidence of complications was significantly higher in the control group than that of experimental group(P<0.05). Conclusion Both treatment methods can effectively relieve the achalasia of cricopharyngeal muscle,but modified double-lumen balloon catheter can reduce the incidence of complications.

Objective:To investigate the effectiveness of heart rate deceleration capacity (DC) measurement in predicting the car-diotoxicity of malignant tumor patients treated with epirubicin-based chemotherapy. Methods:The clinical medical records, including CK-MB and cTnI levels and dynamic electrocardiogram (ECG) parameters before and after each chemotherapy cycle, of 140 patients treated with epirubicin-based chemotherapy were analyzed. Patients were divided into the DC>4.5 ms group and the DC≤4.5 ms group based on the calculated DC values. The CK-MB and cTnI levels and the dynamic ECG parameters of the two groups were compared af-ter two and four cycles of chemotherapy. Results:Patients in the two groups exhibited no statistically significant difference in their rele-vant clinical and pathological data before receiving chemotherapy (P>0.05). However, after four cycles of chemotherapy, the DC≤4.5 ms group showed a significantly greater increase in serum CK-MB and cTnI concentrations over the pre-chemotherapy levels compared with the DC>4.5 ms group. After two and four cycles of chemotherapy, the DC≤4.5 ms group also exhibited a significantly greater in-crease in mean heart rate (beats/min) and supraventricular and ventricular arrhythmia counts (times/24 h) over the pre-chemotherapy values compared with the DC>4.5 ms group (P<0.05). After four cycles of chemotherapy, 23 cases showed abnormally elevated cTnI levels in the DC≤4.5 ms group. In this group, patients with elevated cTnI level exhibited no statistically significant difference in CK-MB and cTnI concentrations, mean heart rates, and supraventricular and ventricular arrhythmia counts compared with those with nor-mal cTnI level before chemotherapy (P>0.05). However, the DC values of patients with elevated cTnI were significantly lower than those with normal cTnI level (P<0.05). Conclusion:The risk of epirubicin-induced cardiotoxicity increased with decrease in DC value. The DC test was shown to be an effective predictor of the risk of epirubicin-induced cardiotoxicity.

PKS gene was screened by PCR from thirty strains of spone-associated bacteria including twenty-one actinomycetes isolated from Craniella anstrialiensis and nine bacillus isolated from Dysidea avara in the South China Sea.As a result,a 669 bp KS domain gene was successfully amplified from Bacillus C89.BLAST analysis showed that the KS domains were most closely related to the KS sequences of Bacillus subtilis subsp.subtilis str.168 with 96% similarity.Phylogenetic analysis demonstrated the KS domain belong to trans-AT KS domains.This study demonstrated the existence of PKS gene in bacteria associated with sponge Dysidea avara for the first time,and provided proof for the hypothesis that sponge-associated bacteria are perhaps the true producers of many novel bioactive compounds in sponge.Meanwhile,this study lays a basis for the microbial screening for polyketide compounds production.

Objective To investigate the effect of active silver ions liquids on incontinence of patients with cerebrovascular diseases.Methods Forty-eight patients with incontinence from cerebrovascular diseases were randomly divided into the treatment group and control one in equal number:the control group was managed with washing and cleaning the perineum with warm water in the morning and evening and the treatment group with active antibacterial liquid silver ion liquids in the afternoon once a day.The two groups were compared in terms of red swelling,itching,papula,blister,local shallow ulcer and abscess in the skin around the perineum as well as the incidence of urinary system infections.Results The treatment group had significantly lower incidences of red swelling,itching,papula,blister,local shallow ulcer and abscess in the skin around the perineum as well as the incidence of urinary system infections,as compared to the control group(all P<0.05).Conclusion Cleaning perineum with active silver ions liquids is effective for the prevention of infections in the skin around the perineum and urinary system infections.

OBJECTIVETo observe the efficacy and safety of Qizhi Jiangtang Capsule (QJC) in treating stage 3b diabetic kidney disease (DKD) patients with macroalbuminuria.

METHODSPatients who conformed to the diagnostic criteria of stage 3b DKD were randomly assigned to two groups according to random digital table, the experiment group and the control group, 84 in each group. All patients received a two-week elution period, and then were treated with basic Western therapy. Patients in the experiment group took QJC, 5 pills per time, 3 times a day, while those in the control group took Valsartan Capsule 160 mg each time, once daily. The observation period of follow-ups was limited within 6 months, and the time points were set as the baseline, 1st month, 3rd month, and 6th month. Systolic blood pressure (SBP), diastolic blood pressure (DBS), 24 h urine protein quantitative (24 h UPQ), plasma albumin (ALB), and serum creatinine (SCr) were detected and recorded, and estimated glomerular filtration rate (eGFR) was calculated. The occurrence of hypoglycemic reaction, coagulation disorder, gastrointestinal tract reaction, allergy, hyperkalemia, doubling of creatinine, and overall adverse events were observed and recorded at same time.

RESULTSFinally 81 patients in the experiment group and 80 patients in the control group were effectively included. Compared with the baseline level, SBP and DBS obviously decreased in the control group at month 1 of treatment (P < 0.05), and more significantly decreased at month 6 of treatment (P < 0.01). SBP at month 1, 3, and 6 of follow-ups; DBS at month 6 of follow-ups was lower in the control group than in the experiment group (P < 0.05). At month 1, 3, and 6 of follow-ups, 24 h UPQ of the experiment group was significantly lower than the baseline level (P < 0.01). It was also significantly lower than the level of the control group at the same time point (P < 0.05). There was no significant difference in 24 h UPQ at month 1, 3, and 6 of follow-ups between the control group and the baseline level (P > 0.05). ALB of the experiment group showed an increasing trend. It was significantly higher than the baseline level at month 6 (P < 0.05), which was also higher than that of the control group at same period (P < 0.05). There was no significant difference in the ALB level in the control group (P > 0.05). SCr of two groups showed an increasing trend. SCr of the experiment group was significantly higher at month 1, 3, and 6 follow-ups than the baseline level (P < 0.05). But the increment of SCr was higher in the control group than in the experimental group, and obviously higher than the baseline levels (P < 0.05). eGFR of both groups showed a decreasing trend. The decrement was higher in the control group than in the experimental group (P < 0.05). The proportion of progression of renal functions at month 1, 3, and 6 of follow-ups in the experimental group was 0.0% (0 case), 9.55% (8 cases), and 21.4% (18 cases), while they were 8.3% (7 cases), 21.4% (18 cases), and 40.5% (34 cases) in the control group. There was no statistical difference in the proportion of progression of renal functions between the two groups at month 3 and 6 of follow-ups (P < 0.05). There was no statistical difference in the incidence of adverse reactions between two groups (P > 0.05).

CONCLUSIONQJC could effectively reduce urinary protein of patients with stage 3b DKD, and delay the progression of renal functions.

OBJECTIVETo investigate the effects and methods of intracranial-extracranial (IC-EC) bypass surgery in the treatment of intracranial aneurysms.

METHODSThe clinical material of 9 cases, who performed IC-EC bypass surgery before occlusion of the parental arteries of intracranial aneurysms, was studied retrospectively, especially how to evaluate the co-lateral circulation of the parental arteries and how to select the different methods of IC-EC bypass surgery.

RESULTSThe co-lateral circulation in 9 cases was not enough to meet the need of the cerebral blood flow after occlusion of the parental arteries of the aneurysms. Revascularization by different methods of IC-EC bypass surgery and then occlusion of the parental arteries, ischemia in the brain area feeding by occluded parental arteries of the aneurysms did not occurred.

CONCLUSIONWhen the co-lateral circulation of the parental arteries of intracranial aneurysm is not enough, the revascularization by different methods of IC-EC bypass surgery is needed before occlusion of these arteries.
