To explore the effects of nutritional risks on clinical outcomes [length of stay (LOS),hospitalization expense & mortality] in chronic kidney disease (CKD) patients.A total of 127 CKD patients completed the screening of nutritional risks by Nutritional Risk Screening 2002 (NRS-2002) within 24-48 hours of admission.The data of nutritional supports within 2 weeks of admission,LOS,hospitalization expense and mortality were collected.① Among them,the prevalence of nutritional risks was 18.1％.And the values were 8.2％,9.4％ and 44.1％ in early,middle and advanced CKD groups respectively; ② LOS and hospitalization expense in nutritional risk group were significantly more than the non-nutritional risk group (12.5 d vs.5.2 d,P =0.00 ; 11 806 vs.5311 yuan,P =0.00).There was a positive correlation between NRS score and LOS or hospitalization expense; ③ The nutritional support rate of nutritional risk group was only 17.4％.The progression of CKD increased the nutritional risks leading to greater LOS and hospitalization expense.We should pay more attention to the nutritional risk screening and nutritional intervention in moderate-advanced CKD patients.

Objective To discuss the clinical features diagnosis and treatment of cerebral schistosomiasis. Methods A to?tal of 166 patients with cerebral schistosomiasis were treated and their clinical data were collected and analyzed retrospectively. Results In 166 cases of cerebral schistosomiasis the confirmative diagnoses of 156 cases were diagnosed according to the clin?ical manifestation etiology immunology and auxiliary examination CT MRI .In among 74 cases were confirmed by pathologi?cal examination 10 cases were diagnosed through to the diagnostic treatment. Totally 102 patients received the oral medication of praziquantel and they all improved and discharged 14?16 days later 64 patients received the craniotomy and praziquantel medication after the operation and 48 patients significantly improved others did not improve or aggravated. There was no opera?tive mortality. Conclusions Neuroimaging and laboratory tests are valuable in the diagnosis of cerebral schistosomiasis. The praziquantel treatment is selected firstly when the diagnosis was established. However in the case of serious intracranial hyper?tension intractable epilepsy and praziquantel treatment fails the surgical treatment is required.

Objective To investigate the clinical effect and to summarize the experience of percutaneous radiofrequency ablation (RFA) of spleen together with splenic artery balloon block in treating hypersplenism due to cirrhosis and portal hypertension. Methods Under the situation of splenic artery occlusion with balloon, RFA of the spleen was performed in 15 patients with hypersplenism caused by cirrhosis and portal hypertension. The mean duration of RFA was (46.4±5.4) min. Routine blood tests were conducted at 3 days, one week, one, 3 and 6 months after the treatment, and abdominal CT angiography was performed one month after RFA. The results were analyzed. Results One patient developed massive bloody pleural effusion at left thorax three days after RFA, which was improved after hemostasis and thoracic drainage. No severe complications occurred in other patients. Abdominal CT angiography performed one month after RFA showed that the ablated extent by RFA was accounted for about 34.3%-71.8% proportion of the spleen, with a mean of (56.20 ±13.09)%. Preoperative blood tests indicated that the count of white blood cells, red blood corpuscles and blood platelets was (3.88±1.75)×109/L, (4.06±0.37) × 1012/L and (48.14± 11.33)×109/L, respectively. One month after RFA the count of white blood cells and blood platelets increased to (5.62±1.61) ×109/L and (132.29±33.20) ×109/L respectively. When compared with the preoperative data, the differences in the count of white blood cells and blood platelets were statistically significant (P<0.05). Conclusion For the treatment of hypersplenism due to cirrhosis and portal hypertension, percutaneous radiofrequency ablation of spleen together with splenic artery balloon block is quite safe and this technique has satisfactory short-term effect.

Objective To study the effects of motor imagery therapy combined with electromyographic (EMG) biofeedback on upper limb function in hemiplegic patients.Methods Sixty hemiplegic stroke patients were recruited and divided into a control group (n=20),an electrical stimulation group (n=20) and a combination group (n=20).All groups received basic medication and routine rehabilitation training once daily for 4 weeks.The electrical stimulation group was also treated with EMG biofeedback,and the combination group with motor imagery therapy plus EMG biofeedback.The Fugl-Meyer assessment (FMA),the modified Barthel index (MBI) and EMG parameters were assessed before and after 2 courses of treatment.Results After 8 weeks of treatment all groups had significantly higher FMA scores and MBI scores,and better integrated EMG values,but the effects in the combination group were significantly better than those in the other two groups.Conclusions Motor imagery therapy combined with EMG biofeedback can more effectively promote recovery of upper limb function in hemiplegic stroke patients.

Objective To evaluate the effect of injecting botulinum toxin A (BTX-A) to the external urethral sphincter on detrusor wall thickness (DWT) and the bladder function of spinal cord injury patients with detrusor-sphincter dyssynergia (DSD).Methods Twenty-one adult patients with DSD due to spinal cord injury were recruited.A single 100 IU dose of botulinum toxin A was injected into their external urethral sphincters via an uhrasound-guided transperineal route.DWT,detrusor leak-point pressure (DLPP),post-void residual volume (PRV) and maximum bladder capacity(MBC) were assessed by urodynamic examination and ultrasound evaluation before and 4 and 8 weeks after the injection.Results Four weeks later a significant decrease in PRV was observed,but no significant difference in DWT,DLPP or MBC.After eight weeks the mean DWT value had decreased by 17％,a significant reduction.There were also significant improvements in DLPP,PRV and MBC at eight weeks compared with the of baseline values.Conclusions BTX-A injection to the external urethral sphincter can reduce DWT and improve bladder function in spinal cord injury patients with DSD.

Objective To observe the effect of acupuncture at nape points plus nerve electrical stimulation on deglutition function and cerebral blood flow in pseudobulbar palsy after cerebral stroke. Method The eligible subjects were randomized into a control group of 35 cases and a treatment group of 33 cases. The control group was intervened by conventional Western medication, while the treatment group was by acupuncture at nape points plus nerve electrical stimulation in addition to the Western medication, once a day, 4 weeks as a treatment course. Result The total effective rates were respectively 93.9%and 80.0%in the two groups, and the treatment group was significantly superior to the control group; after the intervention, the high whole blood viscosity, low whole blood viscosity, hematocrit, and plasma viscosity all dropped markedly in the treatment group, and were significantly different from that in the control group (P<0.05). The Transcranial Doppler (TCD) showed that the blood flow mean velocity (Vm), systolic velocity (Vs), and pulsatility index (PI) of the left vertebral artery, right vertebral artery, and basilar artery in the treatment group were significantly improved after the intervention (P<0.05), and the Vm and Vs of the left vertebral artery, right vertebral artery, and basilar artery in the control group were significantly improved after the intervention (P<0.05), while PI in the control group didn’t show significant improvement (P>0.05). After the intervention, there were significant differences in comparing the Vm, Vs, and PI of the left vertebral artery, right vertebral artery, and basilar artery between the two groups (P<0.05). Conclusion Acupuncture at nape points plus nerve electrical stimulation is effective in improving the deglutition function in pseudobulbar palsy after cerebral stroke, and its action mechanism is plausibly through improving the cerebral blood flow and promoting the recovery of brain function.

Methods:Fresh and sterile gastric cancer samples were managed to single cell suspensions and then were cultured in Met -Hcy + and Met +Hcy - medium separately,the proliferation of tumor cells in different culture media was examined by microcytotoxicity(MTT) assay.Meanwhile,the inhibition rate of tumor cells by ADM、DDP、5 FU、MMC and MTX in Met -Hcy +medium was separately tested. Results:①In Met -Hcy + medium,the human primary gastric cancer cell decreased;②Methionine deprivation in combination with chemotherapy enhanced obviously the killing capacity of each chemotherapeutical agent. Conclusions:①Human primary gastric cancer cells in vitro appears Met dependent.②The combined application of Met -Hcy + medium and different chemotherapeutical agents could enhance the antitumor effect of chemotherapy on primary gastric cancer cells.③MTT assay was an efficient way to examine the sensititivity of methionine starvation therapy combined with individualized chemotherapeutical agents.

Objectives:To study the methionine dependence (Met-dependence) of human primary gastric cancer cells in vitro when Met in the culture medicine was replaced by its precussor homocysteine(Hcy). Methods:Fresh and sterile gaotric cancer samples and normal gastric mucosa were managed into single-cell suspension and were cultured in the Met -Hcy + and Met\++ Hcy\+- medium separately.proliferation of these cells in the two different culture media was examined by cell counter and flow cytometry (FCM). Results:In the Met\++Hcy\+- medium,the growth of primary gastric cancer cells was inhibited,manifesting that the percentage of G 0G 1 tumor cells decreased and that of the S phase increased signiflcantly.However,normal gastric mucosal cells grew well and their cell cycles had no change. Conclusions:Human primary gastric cancer cells are Met dependent in vitro whereas normal gastric mucosal cells have no similar results.

Objectives:To investigate the nutritional status of the maintenance hemodialysis(MHD) patients. Methods:The dietary investigation, anthropometry and biochemical tests were conducted in 46 MHD patients,including weight,triceps skinfold(TSF), arm muscle circumference(AMC), serum total protein(TP), albumin(Alb), prealbumin(PA), transferrin(TF) and ideal weight rate(IBW%).Then nutritional status was evaluated. Results:①The energy intake of most MHD patients was lower than 125.4 kJ/(kg?d) and the mean protein intake was nearly 1.0 g/(kg?d).②According to each single index,the incidence of malnutrition was:39.13% by IBW%, 71.74% by TSF, 58.70% by AMC, 30.43 % by Alb and 82.61% by TF respectively.Only 6.52% patients had all normal paremeters. Conclusions:Malnutrition incidence of MHD patients was as high as 93.48% in our study. The regular nutritional assessment and the nutritional advice are very important for the better clinical outcome in the MHD patients.

Objective To investigate the effectiveness of botulinum toxin A (BTX-A) injection to the external urethral sphincter guided by ultrasound in the treatment of various types of lower urinary tract dysfunction.Methods Twenty-two patients with urinary retention caused by neurological dysfunction (neurogenic bladder) were recruited,of which 18 were men and 4 women.They had various types of lower urinary tract dysfunction including detrusor external sphincter dyssynergia (DESD) in 7,nonrelaxing urethral sphincters in 5,and detrusor underactivity in 10.BTX-A (100 U) was injected into the external urethral sphincter at three different points guided by ultrasound.Clinical effects and urodynamic parameters were compared at baseline and after treatment.Results After treatment the urinary function and urodynamic parameters in each group improved significantly compared with the baseline.Maximum efficacy was observed at the 4th week.In the DESD group,3 patients (43％) had an excellent result and 3 (43％) had significant improvement; in the nonrelaxing sphincter group 3 (60％) had excellent results and 2 (40％) showed significant improvement; in the detrusor underactivity group 5 (50％) had excellent results and 3 (30％) had significant improvement.There were no obvious side effects.Conclusions BTX-A injections guided by ultrasound can accurately locate the external urethral sphincter.It is a simple and repeatable method for the treatment of lower urinary tract dysfunction.
