OBJECTIVETo investigate the feasibility and effect of early removal of the urethral catheter after transurethral plasma kinetic resection of the prostate (PKRP) in the treatment of benign prostatic hyperplasia (BPH).

METHODSWe equally randomized 128 BPH patients treated by PKRP to an experimental group and a control group, urethral catheters removed at 1 -2 days for the former and at 5 -7 days for the latter. We compared the relevant indexes and clinical effects between the two groups.

RESULTSThe baseline data were not significantly different between the two groups. Compared with the controls, the experimental group showed a significantly shorter postoperative hospital stay ([6.8 +/- 1.9] d vs [3.7 +/- 1.5] d, P < 0.05) and lower infection rate (25.0% vs 10.9%, P < 0.05). All the patients were followed up for 3 -6 months postoperatively. At 3 months after surgery, both the experimental and the control groups showed remarkable improvement in the International Prostatic Symptoms Scores (4. 9 +/- 2. 2 vs 5. 3 +/- 2. 3), maximum urine flow rate ([21.5+/- 5.6 ] ml/s vs [19.1 +/-4.9 ] ml/s) , and residual urine ( [ 16.8+/- 10.3 ] ml vs [18.9 +/- 12.3 ] ml), but with no significant differences between the two (P > 0.05) , and no significant differences were observed in postoperative complications (P >0.05).

CONCLUSIONEarly removal of the urethral catheter after PKRP, with its advantages of shorter postoperative hospital stay, lower infection rate, and no influence on the long-term effect, deserves to be recommended as a routine method in the treatment of BPH.

Objective To analyze the impact and quality of life of minimally invasive surgery combined with catheter attract surgery on patients with cerebral hemorrhage.Methods A total of 90 patients with cerebral hemorrhage in our department from February 2013 to De-cember 2014 were randomly divided into invasive group and the control group.Minimally invasive surgery group were given to cerebral hemor-rhage minimally invasive surgery combined with catheter attract surgery,the control group received traditional craniotomy.The postoperative recovery,nerve function scores,quality of life and morbidity between two groups were compared.Results The operation time and edema vol-ume of tissue postoperative 7 days in minimally invasive surgery group was significantly lower than those of the control group.The hematoma clearance rate 1 day after surgery was higher than that of control group,with statistically significant difference(P <0.05).NIHSS scores of two groups were gradually decreased 7 d,15 d,30 d after surgery(P <0.05).NIHSS scores of the minimally invasive surgery group 7 d,15 d, 30 d after surgery were lower than that of control group,with statistically significant difference(P <0.05).The scores of vitality,physiological function,physical function,general health,bodily pain,emotional function,social function,mental health after 6 months of the surgery in the min-imally invasive group was higher than those of control group,with statistically significant difference(P <0.05).The rate of postoperative pulmo-nary infection,electrolyte imbalance,gastrointestinal bleeding in MIS group were lower than those in the control group,with statistically signifi-cant difference(χ2 =5.400 0,4.405 7,4.615 4,P <0.05).Conclusion Minimally invasive surgery combined with catheter attract surgery can improve neurological function and quality of life for patients with intracerebral hemorrhage, and reduce the incidence of complications.

In order to study the interaction relationship between secondary metabolites in Glycyrrhiza uralensis, and find out which secondary metabolite is significantly related to the content of glycyrrhizic acid, artificial applying ammonium glycyrrhetate solution was used to establish a high glycyrrhizic acid environment. The change of the 4 secondary metabolites was analyzed within 72 h after glycyrrhizic acid stimulation, while correlation statistical soft was applied to analyze the correlation of glycyrrhizic acid and other compositions. It turned out that it is feasible to establish high glycyrrhizic acid environment by glycyrrhizic acid root soaking in the concentration of 1.0 mmol x L(-1). There was significant positive correlation between glycyrrhizic acid and liquorice glycosides in short-term glycyrrhizic acid stimulation environment. It is concluded that glycyrrhizic acid accumulation internal of G. uralensis could be effected by artificial exogenous glycyrrhizic acid stimulation in certain case, and its accumulation was significantly related to the content of liquorice glycosides.

An experiment was conducted using cultivated Glycyrrhiza uralensis in age of one year to study the effects of abscisic acid (ABA) on chemical components content and color of G. uralensis. By using different concentrations of ABA spraying on leaves, the change of the chemical component content was analyzed within 45 d after ABA stimulation, and the effects on quality were studied combined with colorimetric analysis data. It turned out that in some sense the content of glycyrrhizic acid and liquiritin had increased within 45 d, especially for liquiritin. After high concentrations of ABA (3.96 mg · L(-1)) stimulating, the content of glycyrrhizic acid rose 52% while liquiritin up 392% within 30 d. Then they both showed a decline in the content of glycyrrhizic acid and liquiritin on 45 d. Color index values of a* and b* were all significantly higher than that of the control group within 45 d, which meant the color of powders turned toward red and yellow. The conclusion was that ABA (3.96 mg · L(-1)) stimulating could not only improve the quality in the traditional sense through the color of G. uralensis, but also in the modern sense by improving the content of glycyrrhizic acid and liquiritin.

Objectives To explore the effects of aging on midgastric transverse band(MTB)and gastric emptying.Methods In our prospective study,57 healthy volunteer were divided into young, middle and old-age groups.After taking test meal labeled by 99mTc-iethylenetriaminepentaacetic acid(99mTc-DTPA), the pictures were collected using double probe single photon emission computed tomography(SPECT).Stomach in each frame of the pictures was divided into proximal, midgastric transverse band(MTB)and distal parts.And half gastric emptying time,gastric remnant rate at 90 min, areas of different gastric parts were tested and calculated respectively.Results Half gastric emptying time of whole stomach was(43.24± 11.87)min,(42.07 ± + 9.31)min and(45.81 ± 10.73)min in young,middle and old-age groups, respectively, with P＞0.05.Among young, middle and oldage groups, half gastric emptying time was(38.09 ± 10.26)min,(37.33 ± 9.28)min and(26.74 ± 12.07)min in proximal stomach, and it was(38.35 ± 12.96)min,(37.73 ± 7.46)min and(46.41 ± 10.74)min in distal stomach,respectively.The half gastric emptying time was significantly reduced in proximal stomach and increased in distal stomach in old-age group(both P＜0.05).The gastric nuclide remnant rate at 90min in total stomach was(30.38 ± 19.32)％,(29.03 ± 10.36)％ and(31.92 ± 13.47)％ ,in young, middle and old-age groups, respectively, with P＞0.05.This rate in proximal stomach was(25.01 ± 12.35)％,(26.36± 15.29)％ and(19.54±8.47)％ among three group, respectively.The rate in proximal stomach was(42.25 ± 12.36)％,(41.56 ±± 9.33)％ and(56.05 ± 11.72)％ among three group,respectively.The gastric remnant rate at 90min was reduced in proximal stomach and was increased in distal stomach significantly in old-age group(both P＜0.05).Compared with young and middle-age group,the old-age group showed no difference in areas of total stomach in all the time, while the areas were reduced in proximal stomach and increased in distal stomach significantly from 30 min to 90 min(all P＜0.05).Total stomach versus proximal and distal stomach showed no difference in count/pixel ratio in all time,while a count/pixel ratio was reduced in proximal stomach and increased in distal stomach significantly from 30 min to 90 min(both P＜ 0.05).Both areas and count/pixel ratio of MTB at 60 min and 90 min were significantly increased in old-age group(both P＜0.05).Conclusions The total gastric emptying is not delayed along with aging, while the gastric emptying is increased in proximal stomach and reduced in distal stomach in the elderly.This abnormity of intragastric distribution of food might be related with larger area of midgastric transverse band.

Objective: To identify the functional domain of ?-Synuclein in affecting mitochondrial function and how the function to be impaired,especially,the mitochondrial membrane potential and the release of Cytochrome c.Methods: Harvest of ?-Syn-N and ?-Syn-△N by PCR,then subcloned into the pCMV-Myc mammalian expression vector.The recombinant plasmids were transfected into HEK293T cells by Lipofectamine 2000.After detecting the protein expression by Western blot,the functional domain was detected by co-immunoprecipitation.The mitochondrial membrane potential through flow cytometry and immunofluorescence,at the same time,the release of Cytochrome c through flow cytometry to detect.Results: The recombinant plasmids were constructed successfully.CO-IP has proved that N-terminal may be the functional domain of ?-Synuclein in affecting mitochondria.Over-expression of N-terminal could depolarize the mitochondrial membrane potential and induce the Cytochrome c releasing in MN9D cells.Conclusion: N-terminal may be the functional domain of ?-synuclein and over-expression of N-terminal could decrease mitochondrial activity.

Fhx/P25 in silkworm, Bombyx mori, one of the main components of silk fibroin, is presumed in previous reports to be expressed exclusively in the posterior silk gland (PSG) of the animal with strict territorial and developmental specificities. On the basis of a large-scale analysis ofthe silkworm EST data, it was found that Fhx/P25 gene is transcribed not only in the posterior silk gland, but in the ovary and in other tissues of the larvae at day 3 of the fifth-instar as well and that this gene has distinct transcription start sites (TSSs) in the posterior silk gland and the ovary. The TSS in the ovary is located about 115 bp upstream sequence of that in the posterior silk gland. Subsequent RT-PCR, FQ-PCR and sequencing have verified the validity of this presumption. In addition, alternative splicing is predicted in pre-mRNA of Fhx/P25 gene and confirmed by RT-PCR. In conclusion, Fhx/P25 gene is not a gene with strictly tissue-specific transcription.Complicated regulation mechanisms may exist for its transcription and expression and it may have other functions to perform.

Objective To study the effects of curcumin mediated photodynamic therapy (PDT)on the growth and proliferation in human cervical cancer cell line H8 in vitro and in vivo,and to investigate its antitumor mechanisms.Methods The effects of curcumin mediated PDT on proliferation of human cervical cancer H8 cell by MTT assay was used to screen the optimal parameter.Changes in cell morphology were observed by May-Gr ünwald-Farbstoff Giemsa staining.The apoptosis rate was estimated by flow cytometry.The effect of PDT by curcumin on the expressions of Bcl-2,P53 and survivin in H8 cells was detected by fluorescence real-time reverse transcription-polymerase chain reaction (RT-PCR).Forty BALB/C nude mice underwent subcutaneous injection of H8 cell line so as to establish animal models,and then were randomly divided into four equal groups:control group,irradiation alone group,curcumin alone group,curcumin PDT group.HE staining and pathological examination were performed.Immunohistochemical study was conducted to detect the protein expression of the apoptosis inhibiting genes of Bcl-2.Results The proliferation inhibition of H8 cells was obvious after PDT when curcumin 5μmol/L with irradiation 100 J/cm2,and with dose dependent manner.Typical morphologic features of apoptosis appeared characterizedly by marked chromatin condensation,nuclear pyknosis and fragmentation,and the appearance of apoptotic bodies.The total apoptosis rate was higher in PDT group [(47.21 ± 4.11)％]than in control group(1.71 ±0.16) ％ (P＜0.01).The mRNA expression of Bcl-2,P53 and survivin in H8 cells were suppressed significantly.HE staining showed remarkable subcutaneous necrosis in the PDT group.Immunohistochemistry showed remarkable down-regulation of protein expression of Bcl-2(P＜0.01).Conclusions Curcumin-mediated photodynamic therapy has a significant killing effect on H8 cells in vivo and in vitro.Its antitumor effect might be related to induction of Tumor cell apoptosis and suppression of Bcl-2 mRNA and protein expression.
