Objective To analyze the effect of intravenous dripping of 3% sodium chloride solution on prevention of diluted hyponatremia during transurethral vaporization of the prostate (TUVP). Methods Eighty-five cases with benign prostatic hyperplasia (BPH) accompanied with typical lower urinary tract symptoms (LUTS) were divided into two groups during undergoing TUVP operation: the control group(n=38) given Ringer's solution dripping (3ml/min) and the concentrated sodium chloride injection group(n= 47) given 3% sodium chloride solution dripping (2～4ml/min). All of the operations were taken via Wolf electric resection system, and the operation time was≥60 min. The complete blood count and serum electrolyte were determined before operation and 60 minutes after operation beginning, and the data were compared between the two groups. Results The decrease amplitude of serum sodium was obviously smaller in concentrated sodium chloride injection group[(1.45±5.14)mmol/L] than that in the control group[(7.79±6.64) mmol/L] 60 minutes after operation beginning (P<0.05). Conclusions Giving 3% sodium chloride solution by intravenous drip during TUVP may reduce the severity of diluted hyponatremia and postpone the occurrence of hyponatremia, and thereby decrease the risk of transurethral resection syndrome.

The mucosa associated lymphoid tissue(MALT) lymphoma represents a distinct subgroup of B cell non Hodgkin lymphomas (NHL) arising from extranodal sites. These neoplasms usually arise from the gastrointestinal tract,salivary gland,thyroid and ocular adnexal, which have been recognized from clinical,pathological and molecular genetics aspects.In this paper we reviewed the investigation progress of MALT lymphoma molecular biology.

Objective To investigate the therapeutic effects of traditional Chinese medicinal herbs(TCMH) on benign prostate hyperplasia(BPH) and their influence on proliferation and apoptosis of prostate cells in experimental mice. Methods A total of 120 male Kunming mice(weight,30 to 40 g)were randomly divided into 5 groups:①normal control group;②hyperplastic group;③normal saline(NS)(negative control)group;④TCMH group;⑤finasteride (positive control) group.Each group included 24 mice.The mice in normal control group were killed and their prostates were weighed.The BPH model was induced by implanting the urogenital sinus in the mice in other 4 groups.In the 61st day,the prostate weight of the mice in hyperplastic group was examined after they were killed;and the mice in the remaining groups were fed with NS,TCMH and finasteride,respectively.In the 91st day,the mice in these 3 groups were killed and their prostates were weighed.The proliferation and apoptosis of the prostate cells of mice in the 3 groups were determined by flow cytometry(FCM). Results The prostates in hyperplastic group [(149.30?8.46)mg] were heavier than those in TCMH group [(85.60?17.97)mg] ( P 0.05). Conclusions The TCMH has a significant therapeutic effects on experimental mice with BPH.The mechanisms may be as follows:TCMH can regulate the relevant genes of the prostate cells so that they can promote the apoptosis of the prostate cells and as a result,the volume and weight of the prostate of the mice are reduced.

[Objective]To evaluate long term curative effect on treatment of developmental dislocation of hip(DDH) in children between 18~36 months old by combined close-reduction method of adductor-cut,close-reduction and frog type plaster fixation.[Method]One hundred and fifty-six children(232 hips) treated by combined close-reduction method in 1993 to 2001 were followed-up with mean follow-up time of 9.2(5.5~14.5) years.There were 77 hips of grade Ⅰ dislocation,95 hips of grade Ⅱ,and 60 hips of grade Ⅲ according to Zhou Yongde grading criteria.Periodical imaginological and hip joint function examinations were evaluated and analyzed.[Result]One hundred and ninety-five hips obtained satisfactory concentric reduction with excellent and good rate of 84.05% according to Zhou Yongde criteria.There were 9 hips with femoral head necrosis at follow-up.Mean preoperative acetabular index(AI) of successful reduction hips was(35.34?5.96)%,and that of failure reduction hips was(44.51?5.32)%.The excellent and good rate were 84.41% in cases of grade Ⅰ hips,85.21% in grade Ⅱ hips,and 81.67% in grade Ⅲ hips.[Conclusion]Combined method of adductor-cut,close-reduction and frog type plaster fixation is an effective way for treatment of DDH of children between 18~36 months old.Preoperative AI but not degree of dislocation is the criteria to determine whether close-reduction is necessary or not.

OBJECTIVE:To optimize the management of drug inventory so as to reduce days of drug turnover. METHODS:Depending on the information management system of the hospital,the method of quality control circle was used to analyze the rea-sons of long days of drug turnover,corresponding measures for continuous improvement were developed,and the effects of the ac-tivities in the quality control circle were evaluated on the basis of the rate of achieving the goal and the growth rate of circle mem-bers. RESULTS:In the activities of the quality control circle,based on the factors such as personnel,drugs and the method,corre-sponding measures were developed in respect of permanent applicants for drugs,the upper and lower limits of drugs to be gotten by the applicant,the increase in the frequency of purchase,“zero inventory”management for part of drugs,and the optimization of the generation program of purchase orders,where the percentage of the drugs with the turnover days within 15 d was increased from 72% to over 85%,the rate of achieving the goal was 107.9%. All the circle members significantly grew as to the application of the method of quality control circle,sense of responsibility,initiative,team spirit,communication and coordination,with growth rate of 12%-28%. CONCLUSIONS:The activities of the quality control circle have achieved a good effect in optimizing the drug inventory management of our hospital and increased the percentage of the drugs with the turnover days within 15 d.

Objective The gastrointestinal tract of neonate becomes colonized with microorganisms from environment and mother immediately after birth. Strong evidences suggested that early composition of the microflora in neonates play an important role for postnatal development of the immune system. This study was designed to investigate the effect of mode of delivery on the development of gut microflora and characteristics of the stool in breast-fed infants by molecular biology methods. Methods Sixty healthy breast-fed term infants were enrolled in the study(including vaginal delivery group and cesarean section delivery group,each group included 30 infants). Anthropometric measurements and stool study were done at 6-week,8-week,10-week,and 12-week. Fecal samples were subjected to quantitative fluorescence real-time polymerse chain reaction assays for the enumeration of lactobacili,bifidobacteria,and subtype of bifidobacteria(bifidobacterium longum and bifidobacterium breve). Results The numbers of lactobacilli and bifidobacterium longum species were less in cesarean delivery group than those in vaginal delivery group(P ＜ 0.05). Stool mean pH was lower in vaginal delivery group than that in cesarean section delivery group(P ＜ 0.05). There were no differences in stool characteristics and growth between two groups. Conclusions Cesarean section is associated with the decrease of bifidobacteria and lactobacilli in breast-fed term infants.

Background Hypertension,ischemia and hypoxia induce the increase of glutamate level in eye tissue and furthermore produce excitatory damage and apoptosis of retinal ganglion cells(RGCs).At present,the study on the protection of traditional Chinese medicine on glutamate-induced retinal excitatory damage is lack.objective Present study was to explore the protective effects of Huoxue huayu decoction,a Chinese herbal recipe,on RGCs in acute ocular hypertension model. Methods Fony-five healthy clean Wistar rats were divided into three groups randomly.The acute ocular hypertension models were established in 40 Wistar rats by injecting the normal saline solution into the anterior chamber to elevate the intraocular pressure for 60 minutes.Huoxue huayu decoction of 4 ml was administered intragastrically once per day in 20 model rats.Other matched 5 normal Wistar rats served as normal control group.The rats were sacrificed on 1,3,7 and 14 days after modeling and the retinas were isolated for the histopathologieal and uhrastructure examination.Expression of glutamate transporter in the retina of acute ocular hypertension and normal rat retina were detected using quantitative real-time polymerase chain reaction.The utilization of animals followed the Association for Research in vision and Ophthalmology. Results After acute ocular hypertension.the retina thickness attenuated and the numbers of RGCs decreased under the light microscope in 1,3,7 and 14 days after modeling in comparison with normal control rats.The degradation of the organelle and edema as well as changes of cell nuclei were seen in model rats under the transmission electron microscopy.The expression of glutamate transporter mRNA in model group and glutamate transporter group was rapidly elevated in the first day (P<0.05),descended at the third days(P<0.01)and returned to the normal level 7 days later(P>0.05).Conclusion Huoxue huayu decoction can protect the retina against RGCs damage in the acute ocular hypertension by elevating the expression of glutamate transporters in retina.

Objective To analyze postoperative effect of a new rectopexy technique with Douglas pouch elevation for complete rectal prolapse (CRP) in adults.Methods From January 2010 to May 2011, 52 CRP cases were treated by rectopexy with Douglas pouch elevation.In terms of different surgical techniques, patients were divided into two groups : Group A (n =28) received laparoscopic rectopexy with Douglas pouch elevation;and Group B (n =24) received laparoscopic rectopexy with Douglas pouch elevation combined with procedure for prolapse and hemorrhoids (PPH).Rectal prolapse, constipation, and fecal incontinence in the two groups were assessed respectively before surgery, and on the 6th, 12th, and 24th month after surgery, postoperative complications were evaluated with severe grading of surgical complications.Results Symptoms of rectal prolapse disappeared at half a year after surgery in all patients, and relapsed to different extent afterwards.However, two years after operation, the status of rectal prolapse in Group B tended to be stable.The trend of constipation after surgery was consistent with that of rectal prolapse.In addition, fecal continence improved gradually on half a year after surgery in the two groups and recovered to the optimal status in the first postoperative year.However, in the second year, the results of fecal incontinence reduced slightly in Groups A, and Group B became stable.Two years after surgery, four cases in Groups A relapsed while there was no recurrence in Group B.Difference of Grade I to Grade Ⅲ complications among the two groups was statistically insignificant (x2 =0.05, P ＞ 0.05).Conclusions The clinical effect of laparoscopic rectopexy with Douglas pouch elevation associated with the procedure for prolapse and hemorrhoids (PPH) is better than that without PPH for female and male CRP patients with severe symptoms.
