BACKGROUND: Homogenate meals, as a replacement of normal diet, can be used in either hospitals or families. The homogenate meal as nutritious supplements should contain multiple components when it is applied in senior patients with chronic diseases because of the longterm application and complex complications.OBJECTIVE: To investigate the impact of longterm tube feed of finished product of homogenate meal on the nutritious supplements of senior patients.DESIGN: A cross-sectional study based on diagnosis.SETTING, PARTICIPANTS and METHODS: Totally 24 senior patients with chronic diseases who had been used self-made finished products of homogenate meal for more than 1 year were selected for nutritious supplement from Guangzhou General Hospital of Guangzhou Military Area Command of Chinese PLA. The changes of nutritious index at before and 4, 8 and 12 months after supplement were observed.MAIN OUTCOME MEASURES: Anthropometric measurement index and laboratorial index of 24 senior patients with chronic diseases before and after intervention were compared.RESULTS: Serous albumin at before nutritious supplements, and 4, 8 and 12 months after supplements were[ (36.4 ± 4.03), (36.60 ± 4.42),(38.20 ± 3.77), and(40.40 ± 3. 33) ] g/L respectively. Phosphorus and peripheral lymphocytes were significantly heightened while blood sugar began to decrease since 4 months after intervention, which all had significant differences compared with that of before intervention( t =2. 196 -2. 356,P <0.05; t=2.958-3.431. P <0.01) .Anthropometric measurement index also improved compared with that of before intervention.CONCLUSION: Longterm application of finished product of homogenate meal can improve the nutritious status of senior patients with chronic diseases.

Objective To study the relationship between MRI and clinical profiles of periventricular leukomalacia (PVL) in children Methods The clinical and MRI findings in 34 cases with PVL were retrospectively analyzed Results (1) Periventricular hyperintensity on T 2WI was more prominent in the preterm group than that in the term group, and P value was 0 000; (2) Cortical lesion and subcortical leukomalacia was seen in 9 of 19 cases in the children with PVL born at term, but detected in only 1/15 in the preterm group P value was 0 020; (3)Seizure was common in term children P value was 0 036; (4) The degree of reduction of periventricular white matter correlated with motor impairment and mental retardation in all children, and P values were 0 002 and 0 000, respectively The thinning of the corpus callosum also correlated with mental retardation and P value was 0 012 The degree of reduction of periventricular white matter correlated with visual impairment in preterm group Conclusion The end stage PVL can been clearly displayed by MRI, and gestational age and clinical manifestation were closely related to the findings of MRI

AIM:To investigate the role of high glucose in primary hepatocytes of mice fed with a high fat di-et.METHODS:Male C57BL/6J mice were fed a high fat (45%of calories) diet ad libitum for 6 weeks to induce hepatic steatosis.Primary hepatocytes were isolated from the mouse liver by the 2 step collagenase perfusion method .The cells were incubated in low glucose ( 5 mmol/L ) , low glucose plus mannitol ( 30 mmol/L ) , or high glucose ( 35 mmol/L ) DMEM medium for 12 h.The cell viability , apoptosis , mitochondrial membrane potential , and caspase enzymatic activities were measured.Furthermore, proteins related to the stress-sensitive signaling pathway of regulating high glucose-induced apoptosis in primary hepatocytes were determined by Western blotting .RESULTS:Incubation with 35 mmol/L glucose re-sulted in a significant decrease in cell viability and an increase in apoptosis , whereas mannitol had no significant effect on the cell viability or apoptosis .A progressive depolarization of the mitochondria , an increase in cytosol cytochrome C and a dramatic decrease in mitochondrial cytochrome C in high-glucose stressed hepatocytes were observed .The enzymatic activi-ties of caspase-9 and caspase-3, but not caspase-8, were significantly increased in high glucose-stressed hepatocytes ( P<0.05).High glucose treatment suppressed the expression of Bcl-2 and Bcl-xL, while it increased the expression of the pro-apoptotic factor Bax .CONCLUSION:High glucose stress reduces mitochondrial membrane potential , initiates mitochon-dria-mediated apoptotic pathways and promotes apoptosis of hepatocytes with steatosis .This may be an important pathologi-cal mechanism of hyperglycemia-induced progression of nonalcoholic fatty liver disease .

Objective To investigate the effect of blood pressure control for early enlargement of hypertensive intracerebral hemorrhage.Methods A total of 96 patients were divided randomly into intensive blood pressure lowering group (n = 48 )and standard antihypertensive group(n=48).Patients were checked head CT and was evaluated defect of nerve function score immedi-ately when they arrive at hospital and after 24 hours.Then the clinical curative effect was evaluated.Results The defect of nerve function score in intensive blood pressure lowering group was lower than that of the standard antihypertensive group(P <0.05 ). The hematomas volume within 24 hours of admission and the rate of hematoma enlargement of intensive blood pressure lowering group were sharply smaller than those of standard antihypertensive group(P <0.05).Conclusion Controlling blood pressure ac-tively could decrease ratio early enlargement of hematoma and defect of nerve function score in patients with hypertensive cerebral hemorrhage.

Purpose:To determine the efficacy of paclitaxel in human bladder cancer lines and to investigate the mechanism by which paclita xel induce apoptosis in human bladder cancer cells. Methods:BIU-87, 5637, T24 and EJ bladder cancer cell lines wer e cultured by techniques of cell culture in vitro. The cytotoxic activity an d apoptosis induction abilities of paclitaxel were analyzed by MTT and Annexin- V assay as well as DNA cytometry , respectively. The effects on the cell cycle w ere assessed by flow cytometry of propidium iodide. The expressions of Bcl-2, B ax, p53 and Caspase3 proteins were determined by flow cytometry immunofluorescen ce. Results:Paclitaxel dose-dependent inhibition of cell prolifera tion was seen.Paclitaxel induced G_2/M arrest (71.29% and 64.57%) which was maximal in 5637 and EJ cell lines. While paclitaxel at 1?g/ml concentration ex posure to 5637 12h, 14h and 48h respectively, the apoptosis rates of the respect ive times were 5.0%, 12.9%, 27.6%. The expression of genes p53 and Bcl-2 was no t influenced, whereas the expression of Bax and Caspase3 had increases time-dep endently after exposure to paclitaxel. The analysis of Annexin-V showed a drama tic dose-dependent increase of apoptosis. Conclusions:Paclitaxel inhibited bladder cancer cells prolifera tion and had more effect on those cells whose grade was lower and doubling time was longer. Paclitaxel could block G_2/M arrest, and induce apoptosis by th e path of Bcl-2/Bax in bladder cancer cell lines.

OBJECTIVETo compare the differences in the clinical efficacy between Guan's quadruple therapy for kidney disease and the conventional western medication in the treatment of chronic renal failure (CRF).

METHODSEighty patients were randomized into an observation group and a control group, 40 cases in each one. In the observation group, besides the physician instruction of low protein and low phosphorus diet in the two groups, Guan's quadruple therapy for kidney disease was applied, including (1) the isolated herbal moxibustion at Shenshu (BL 23) and Pishu (BL 21), or Ganshu (BL 18), Zusanli (ST 36) and Guanyuan (CV 4) alternatively; (2) acupuncture at the auricular points such as shen (CO10), jiaogan (AHR6), Shenshangxian (TG2), fei (CO14) and pizhixia (AT4); (3) injection of mixture of astragalus injection and lidocaine injection at Feishu (BL 13), Pishu (BL 21), Shenshu (BL 23) and the others; (4) modified Shenshuai Yihao decoction according to syndrome differentiation. In the control group, the conventional western medication was used. After 6 months of treatment, the differences were observed between the two groups in the clinical efficacy, serum creatinine (Scr), blood urea nitrogen (BUN), endogenous creatinine (Ccr) and 24 h urine protein quantitation (UPQ).

RESULTSIn the observation group, after treatment, the remarkably effective rate was 50.0% (20/40) and the total effective rate was 82.5% (33/40), which were superior to 25.0% (10/40) and 45.0% (18/40) in the control group (both P < 0.05). After treatment, the levels of Scr, BUN and 24 h UPQ were reduced apparently (all P < 0.05), and the level of Ccr was increased apparently in the two groups (both P < 0.05). After treatment, the levels of Scr, BUN and 24 h UPQ were reduced much more apparently in the observation group as compared with those in the control group (all P < 0.05).

CONCLUSIONGuan's quadruple therapy for kidney disease achieves a better efficacy on CRF compared with the conventional western medication. This therapy improves renal functions, relieves clinical symptoms and physical signs and benefits the life quality of patients.

OBJECTIVETo investigate the feasibility and the mid-term effects of unilateral pedicle screw fixation and transforaminal lumbar interbody fusion in treating lumbar degenerative diseases.

METHODSFrom August 2005 to May 2010, 56 patients with lumbar degenerative diseases underwent lumbar posterolateral fusion,their clinical data were retrospective analyzed. The patients were divided into two groups (unilateral group and bilateral group) according to fixation methods,27 patients in unilateral group who were underwent unilateral pedicle screw fixation, including 18 males and 9 females with a mean age of (57.5 ± 7.1) years old (ranged from 41 to 66 years); and 29 patients in bilateral group who were treated with bilateral pedicle screw fixation (on the basis of the above, with contralateral vertebral pedicle screw fixation), including 19 males and 10 females with a mean age of (54.6 ± 5.1) years old (ranged from 43 to 68 years). The clinical data such as operation time, blood loss volume, hospitalization time and cost were compared between two groups. JOA score system was used to evaluate the neurological function. And fusion status and cage-related complication were also analyzed.

RESULTSAll patients were followed up from 36 to 60 months with an average of 45.8 months. No iatrogenic nerve, blood vessels or organs injury were found during operation. Operation time, blood loss volume, hospitalization time and cost in unilateral group were better than that of bilateral group (P < 0.05). There was no significant difference in JOA score between two groups (P > 0.05). Two patients in unilateral group developed with cage related complications, 1 case was cage displacement and 1 case was cage subsidence, while 2 patients in bilateral group developed with complications of no-fusion, and there was no significant differences between two groups (P = 0.58).

CONCLUSIONUnilateral pedicle screw fixation is a satisfactory method and can obtain good effects in treating lumbar degenerative diseases in mid-term, however, the indications should be well considered.
