1.Pharmacological mechanisms and clinical application of mannitol in intracerebral hemorrhage
International Journal of Cerebrovascular Diseases 2009;17(2):115-117
One of the important therapeutic measures in the acute stage of cerebral hemorrhage is to treat cerebral edema and lower intracranial pressure. Mannitol, an osmotic dehydrant, is most widely used in clinical practice. Its major effects include the reduction of intracranial pressure and cerebral edema and prevention of cerebral herniation. Besides, mannitol scavenges oxygen free radicals and protects brain cells. So it has extremely important significance in reducing the mortality of intracerebral hemorrhage.

Objective To explore the influence of automatic and semi-automatic hemodialyzer reuse method on hemodialyzer reuse effect. Methods 1728 dialyzers were randomly divided into automatichemodialyzer reuse group and semi- automatic hemodialyzer reuse group with 864 dialyzers in each group. Thetime of douching and testing, the cost of sterilization,the frequency of the pyrphgen reaction,the broken dialyzer membrane and re-examined dialyzer between the two groups were measured. Results The time of douching dialyzer, testing of total cell volume and pressure in the semi- automatic hemodialyzer reuse group was (26.443±3.237), (2.172±0.128) and (2.157±0.090) minutes respectively,while the automatic hemodialyzer reuse group was (5.793±0.193), (1.257±0.118) and (1.110±0.076) minutes respectively. The frequency of re-examined dialyzer in testing total cell volume and pressure was 499(57.755%), 243(28.125%) respectively. At the same time, all dialyzer in semi-automatic hemodialyzer reuse group could be examined successfully at a time. The cost of sterilization in automatic henmdialyzer reuse group was (9.330±0.138)yuan. No pyrogen reaction and broken dialyzer membrane happened. Conclusions The semi-automatic bemodialyzer reuse group can retrench cost during perfusion,but consumes long douching time, lacks matching detection equipment, difficult to detect, and is not easy to read data and has high re- examination rate. while in the automatic hemodialyzer group, it is convenient of douching and detection, but the cost of sterilization and equipment is high, and clinical demand can be fulfilled only when the dialysis center can allocate reasonable number of the machines.

Objective To evaluate the effects of femoral artery wall thickness, stillness and ankle brachium index(ABI) on clinical manifestation of peripheral vascular disease(PVD) in type 2 diabetes mellitus. Methods According to the presence of lower limb and reduced ABI (ABI<0.9), 151 patients with type 2 diabetes were divided into group of patients with and without PVD symptoms, and group of patients with and without reduced ABI. Intima-media thickness of femoral artery (FA-IMT) and stiffness of femoral artery (FA-β) were measured by ultrasound. FA-IMA and FA-β of femoral arteries were compared between group of patients with and without PVD symptoms as well as between group of patients with and without reduced ABI. Correlation between FA-IMT and FA-β was analyzed. Factors affecting symptoms of lower limb and ABI were evaluated by multiple logistic regression analysis. Results FA-IMT and FA-β in group of PVD symptoms were higher than those in group without PVD symptoms. Similarly, patients with reduced ABI had greater FA-IMT and FA-β than those without. However,there was no correlation between FA-IMT and FA-β in group of PVD symptoms. Multiple logistic regression analysis indicated that the presence of PVD symptoms was associated closely with increased FA-β, whereas reduced ABI was associated closely with FA-IMT. Conclusions The stiffening of arterial wall has a significant impact on PVD manifestations,particularly on the leg symptoms in patients with type 2 diabetes.

BACKGROUNDTo evaluate the efficacy and safety of weekly paclitaxel and ifosfamide in the treatment of advanced non-small cell lung cancer.
METHODSTwenty-three patients with advanced non-small cell lung cancer received paclitaxel 50-65 mg/m² IV weekly on days 1, 8, 15, and IFO 1.3 g/m² IV on days 2-4. The schedule was repeated every 28 days for two or three cycles as a course.
RESULTSOne patient had complete response and eight had partial response. Eleven patients had stable disease and three had progressive disease. The overall response rate was 39.1%. Twenty patients were followed-up. The 1-year survival was 40%(8/20) and the median survival duration was 8.9 months. The main toxicities were hematological toxicity (leukopenia, 69.6%, 16/23) and nausea/vomiting (47.8%, 11/23).
CONCLUSIONSCombined chemotherapy of weekly paclitaxel and ifosfamide is a good regimen for advanced non-small cell lung cancer with good efficacy and well-tolerated side effects.

Objective To investigate the predictors of systemic inflammatory response syndrome (SIRS) in patients with acute ischemic stroke. Methods The patients with acute ischemic stroke admitted to hospital from January 2010 to April 2014 were enroled. The demographics, vascular risk factors, baseline clinical data, and laboratory tests in both groups were colected. Flow cytometry was used to analyze the peripheral blood T helper cel (Th) subgroup. Double antibody sandwich enzyme-linked immunosorbent assay was used to detect the levels of peripheral blood interferon-γ (IFN-γ) and interleukin-4 (IL-4). Results A total of 143 patients with acute ischemic stroke were enroled, including 56 in a SIRS group and 87 in a non-SIRS group. Univariate analysis showed that there were significant differences in the history of hypertension, history of stroke, baseline systolic blood pressure, low-density lipoprotein cholesterol level, National Institutes of Health Stroke Scale (NIHSS) score, percentage of Th1 cels, and IFN-γ concentration in patients of both groups (al P < 0. 05). Multivariate logistic regression analysis showed that the NIHSS score ≥6 (odds ratio [ OR] 2. 40, 95% confidence interval [ CI] 1. 24 - 5. 15, P = 0. 008), decreased percentage of Th1 cels (OR 2. 81, 95% CI 1. 51 - 6. 83, P = 0. 013), and decreased IFN-γ concentration (OR 4. 63, 95% CI 1. 01 - 9. 72, P = 0. 004) were the independent predictive factors for occurring SIRS in patients with acute ischemic stroke. Conclusions Severe neurological deficit, decreased percentage of Th1 cels or decreased IFN-γ level may increase the risk of acute ischemic stroke patients with SIRS.

Objective To investigate the relationship between the right-to-left shunt(RLS)detected with contrast-enhanced transcranial Doppler (c-TCD) and recurrent stroke in patients with cryptogenic stroke.Methods The consecutive patients w ith ischemic stroke w ere enrol ed. The patients w ith cryptogenic stroke w ere screened according to the TOAST criteria. They w ere divided into either a RLS positive group or a RLS negative group according to the c-TCD findings, and then they w ere fol ow ed up for a period of one year. They w ere also divided into a recurrent group and a non-recurrent group according to w hether they had recurrence or not. Results A total of 118 patients w ith cryptogenic ischemic stroke w ere enrol ed, including 46 in the RLS positive group, 72 in the RLS negative group, 10 in the recurrent group, and 108 in the non-recurrent group. There w ere no significant differences in demographic and baseline data betw een the RLS negative group and the RLS positive group. There w ere significant differences in RLS positive rate (7/10 vs.39/108; P=0.046) and proportion of patients with server RLS (2/10 vs.1/108; P=0.019) betw een the recurrent group and the non-recurrent group. Multivariate logistic regression analysis show ed that the positive RLS w as an independent predictor of recurrent stroke (odds ratio 4.896, 95% confidence interval 1.135-21.120;P=0.033). Conclusions The positive RLS may be an independent risk factor for the recurrence in patients w ith cryptogenic ischemic stroke.

Objective:
To explore the clinical safety and feasibility of enterostomy using running suture of dermis and seromuscular layer in laparoscopic-assisted radical resection for rectal carcinoma.
Methods:
From May 1, 2017 to May 1, 2018, 46 patients who underwent laparoscopic-assisted radical resection for rectal carcinoma with enterostomy using running suture of dermis and seromuscular layer in Cancer Hospital, Chinese Academy of Medical Sciences were retrospectively enrolled in this study. Data regarding clinicopathologic characteristics, operation and postoperative outcomes, stoma-related complications and functions of stoma were collected and analyzed.
Results:
All of the 46 patients successfully underwent this operation. Among them, 30 patients underwent laparoscopic-assisted abdominoperineal resection for rectal cancer with sigmoidostomy and 16 patients underwent laparoscopic-assisted low anterior resection for rectal cancer with loop ileostomy. The mean operation time was 115.3 minutes and intraoperative blood loss was 86.1 ml. The mean time for enterostomy was 14.1 minutes. The average time to flatus, time to fluid diet intake and length of hospital stay were 1.8 days, 2.9 days and 6.5 days, respectively. During the follow-up period, three patients suffered from stomal edema, two patients suffered from parastomal hernia, and two patients suffered from skin inflammation surrounding stoma. None of re-operation related stoma and severe mobility such as stomal stenosis, stomal necrosis, stomal prolapse, stomal retraction and stomal mucocutaneous separation occurred. Thirty-five patients recovered with satisfactory stomal function, two with middle function and one with poor function.
Conclusion
Enterostomy using running suture of dermis and seromuscular layer in laparoscopic-assisted radical resection for rectal carcinoma is a safe and feasible procedure with a satisfactory short-term effect.
