A continuous noninvasive method for blood pressure (BP) estimation by pulse wave transit time (PWTT) is described. A constant linear relation is available between PWTT and BP, but characteristic parameter for the relation is different for different persons. According to hydrostatics, BP in some vessel changes with different body postures. In this paper, the difference, i.e. △BP, between two BP values with different body postures is gained. ECGs and surface pulse waves are also obtained, and then values of PWTT are calculated. Through the A BP and PWTT acquired above, parameter b of BP equation can be determined, and then parameter a is computerized through the measurements and one BP value. Thus a BP equation is got, which can be used to estimate BP values through continuous measurement of PWTT. Compared with the value from invasive BP measurement, the value from this method has an error rate less than 5%. The method is feasible for noninvasive continuous BP monitoring.

As a new biomarker and a member of transforming growth factor super family,growth differentiation factor-15 (GDF-15) is increased in some pathological situations,and plays a positive role.Increasing evidence from animals and clinical trials has indicated that GDF-15 is a promising biomarker to be used for diagnosis,screening,risk stratification and prognosis evaluation in acute coronary syndrome,heart failure and pulmonary vascular diseases.However,there are still numerous challenges and problems need to be resolved in the future,such as appropriate cut-off value in diagnosis and risk stratification in different cardiovascular diseases,improvement in sensitivity and specificity,and combinational application with other biomarkers.

Objectives To investigate the expression of TGF-?receptors and signaling protein SMADs mRNA in psoriatic lesional and nonlesional skin,and to analyze their role in the pathogenesis of psoriasis.Methods Expression of TGF-?receptorⅠ,TGF-?receptorⅡmRNA and different SMADs(SMAD2,3,4,6,7)mRNA was investigated by real time PCR method in lesional and nonlesional skin of13psoriatic patients and10normal controls.Results The mRNA expression of TGF-?receptors and all kinds of SMADs was significantly down-regulated in psoriatic lesional skin compared with normal skin con-trols(P0.05).Conclusions There is down-regulated TGF-?pathway in psoriatic lesional skin,which may further indicate that lack of TGF-?mediated growth inhibition might play an important role in the pathogenesis of psoriasis.

Cerebral venous thrombosis (CVT) refers to thrombosis of the intracranial veins and sinuses, which is a rare type of cerebrovascular disease.Due to this highly variable and nonspecific clinical presentations, CVT can be difficult to diagnose.Understanding the pathophysiology and etiology of CVT helps to understand its clinical symptoms and imaging findings and guide the treatment.This article reviews the related advances in the pathophysiology and etiology of CVT.

Objective To investigate the efficacy of ultrashort and short-acting insulin after subcutaneous insulin infusion pump under glucose monitoring in treatment of diabetes.Methods 110 cases with type 2 diabetes were selected,they were randomly divided into two groups with a random number table:the study group and the control group,55 cases in each group.The study group was treated with short -acting insulin after subcutaneous injection of insulin pump,the control group was treated with short -acting subcutaneous insulin infusion by insulin pump therapy, glucose monitoring system was used to monitor glucose during treatment of the two groups.The clinical efficacy after a month of treatment was observed.Results Before treatment,fasting blood glucose(FPG),postprandial 2 h blood glucose(2h PG),bedtime blood glucose of the two groups had no statistically significant differences.After treatment, FPG and 2hPG,bedtime blood glucose in the study group were (6.01 ±1.06)mmol/L,(7.90 ±0.50)mmol/L, (7.13 ±0.95)mmol/L respectively,which of the control group were (5.98 ±1.04)mmol/L,(7.91 ±0.48)mmol/L, (7.14 ±0.94)mmol/L,which were significantly lower than before treatment (t =9.843,23.669,13.569,9.683, 22.881,13.710,P <0.05),the two groups after treatment showed no significant differences(P >0.05).The blood glucose time and insulin dosage in the study group were (5.59 ±1.30)d,(39.98 ±11.01)u/d,which of the control group were (6.98 ±1.40)d,(51.89 ±11.97)u/d,and there were significant differences between the two groups(t =1.825,5.431,P <0.05).The mean blood glucose,blood glucose standard deviation,time percentage of blood glucose≥10 mmol/L,time percentage of blood glucose≤3.9 mmol/L in the study group were (5.95 ±0.61 )mmol/L, (1.28 ±0.25)mmol/L,(14.16 ±2.13)%,(6.35 ±1.45)%,which in the control group were (6.59 ±0.94)mmol/L, (1.54 ±0.29)mmol/L,(15.15 ±2.14)%,(7.96 ±1.42)% respectively,and the differences were statistically significant between the two groups(t =4.236,503.6,2.432,5.883,P <0.05).Conclusion Glucose monitoring system in monitoring blood glucose is accurate and reliable,ultra -short -acting insulin after subcutaneous insulin pump infusion in treatment of diabetes is better than short -acting insulin.

Objective To investigate the clinical effects of phacoemulsification combined with goniosynechialysis on the treatment of primary angle-closure glaucoma (PACG) with cataract. Methods The retrospective review included 71 patients (98 eyes) with PACG and cataract treated in Tianjin Huanghe Hospital. Patients were underwent phacoemulsification and intraocular lens implantation combined goniosynechialysis. Among these patients, there were 21 males (30 eyes) and 50 females (68 eyes). Patients ranged in age from 53 to 94 years old, everage (73.94 ± 6.43) years old. They were divided into acute angle-closure glaucoma with cataract group (47 patients, 64 eyes) and chronic angle-closure glaucoma with cataract group (24 patients, 34 eyes). The visual acuity, intraocular pressure (IOP), anterior chamber angle, anterior chamber depth (CCT), topical and oral medications and surgical complications were observed before and after surgery in two groups. All the patients were followed up for 6 months. Results At the end of follow-up, postoperative visual acuity, IOP, CCT, anterior chamber angle and IOP-lowing medicine (topical and oral medications) were all improved in the two groups compared with those of preoperative levels (all P < 0.01). There were no statistical differences in preoperative or postoperative average visual acuity, IOP and anterior chamber angle between two groups (all P > 0.05). Values of CCT were significantly higher before and after operation in chronic angle-closure glaucoma with cataract group than those of acute angle-closure glaucoma with cataract group (P < 0.05). No drug-control rate of intraocular pressure was 76.5% (26/34) for chronic angle-closure glaucoma with cataract group than that of acute angle-closure glaucoma with cataract group (100%, 64/64). There was no need on topical medication in acute angle-closure glaucoma with cataract group. There were 14 eyes had corneal edema and 8 eyes appeared iris fibrous exudation in two groups, while no other serious complications. Conclusion For patients with PACG and cataract, the combined surgery of phacoemulsification and goniosynechialysis is a safe and effective therapy that can improve visual acuity and reduce IOP with fewer complications.
