Objective The aim of the study was to investigate the effects of inflammation on the biological be-haviors of the VF -MSCs and provide the theoretic basis for the repair of the vocal folds which were damaged by in-flammation .Methods The inflammatory vocal fold tissues and normal vocal fold tissues were respectively derived from the vocal cord polyp and normal tissues of the hypopharyngeal carcinoma patients .The HE staining ,masson trichrome staining and elastin van gieson (EVG) staining were performed to detect the effects of inflammation on the collagenous fiber and elastic fibers of the vocal fold lamina propria .The cell colony formation analysis and MTT cell growth curve were used to detect the effects of inflammation on the proliferation of VF -MSCs .The effects of in-flammation on the multi-directional differentiation of VF -MSCs were evaluated by inducing the VF -MSCs to dif-ferentiate into osteoblasts and lipoblasts .Results The results of masson trichrome staining and EVG staining showed that in the inflammatory vocal fold lamina propria collagen fibers became thicker and the amount of collagen fibers increased ,while elastic fibers became thinner and the amount of elastic fibers decreased .Compared with the vocal fold mesenchymal stem cell (VF-MSCs) in normal vocal folds ,VF-MSCs in inflammatory vocal folds pro-liferated more significantly ,but the osteogenic differentiation and adipogenic differentiation of VF -MSCs in inflammatory vocal folds were restrained .Conclusion Inflammation enhanced the compressive resistance ,abated the elasticity , and restrained the multi -directional differentiation of VF -MSCs .

Objective This paper aimed to evaluate the effect of preoperative embolization on the intraoperative blood loss of sacrum chordoma.Methods forty patients involved with the spinal chordoma were retrospectively analyzed in this study.The preoperative embolization group consisted of 16 sacrum chordoma patients were embolizationed by gelatin sponge particles (10 male and6 female)age from 35 to 71 years old,(mean 57.9 years) ; and the control group consisted of 4 sacrum chordoma patients (3 male and 1 female),age from 43 to 61 years old(mean 51.8 years).analyzed the predictive value of preoperative embolization in correlation with the intraoperative blood loss.Results The mean blood loss (2025.0 ±818.5)ml of sacrum chordoma in the preoperative embolization group was insignificantly than that (1950.0 ± 802.1) ml in the control group,(P ＞ 0.05).Conclusion The study shows that the preoperative feeding artery embolization of the spinal tumor has no significant effect on the intraoperative blood loss in the surgical excision of the sacrum chordoma.

Objective To know the eutrophic state of Fenhe 1 reservoir. Methods The eutrophic level of Fenhe reservoir 1 was evaluated through measuring transparence,the total concentration of nitrogen(TN),phosphorus(TP),chlorophyll-a level(Chla) and the total count of the algal cells and calculating water TLI(∑). Results Water transparence in low water period was higher than that in common water period,TN concentration in low water period was higher than that in common water period,and it obviously exceeded the related standard limit in Surface Water Environment Quality Standard (GB3838—2002); TP concertration in common water period and low water period did not exceed the limit; Chla level was low;TLI(∑) in common water period and low water period was lower than 50. The total count of the algal cells was 1.67?106/L in low water period,which was much more than that(9.5?104/L) in the common water period. Conclusion Fenhe reservoir 1 is in mesotropher state.

Objective:To review the clinical efficacy of botulinum toxin type A(BTX-A)in the treatment of trigeminal neuralgia (TN).Methods:The main bibliographic databases were searched from English and Chinese literatures on the topic and the refer-ences of the identified articles were also searched for additional studies.2 reviewers assessed the quality of the included studies and extracted data duplicate.Results:3 Chinese and 1 English reports with 203 participants were included.However,substantial hetero-geneity(I2 =77%)precluded meta-analysis and the results were individually described.3 trials reported that BTX-A was more effec-tive than the control and 1 showed no difference between groups.Adverse effects of BTX-A were reported in 4 reports and were mild to moderate.Conclusion:BTX-A is effective in treating TN with few adverse effects.However,the evidence is weak because of a few studies included and most of them with low methodological quality.Further studies with high quality are needed to testify the evidence.

Methods Fifty-one patients with hypertensive cerebral hemorrhage were randomly enrolled into the orientation square group( n=27)and the CT orientation routine group (n=24). The puncture point was fixed by certain wayin each group. Both groups received the same intracranial hematoma microinvasive craniopuncture scavenging technique. The punctural precision,the time spended for puncture orientation and the curative effect in two group were observed and compared. Results The deflected rate(18.5%)of the orientation square group was lower than that routine group significantly(50.0%)(P

Objective To evaluate the effect of immune fluorescence chromatography on glycosylated hemoglobin (HbA1c). Methods The precision of immune fluorescence chromatography was evaluated with samples of 6.0% and 8.0% fixed value. Group of High performance liquid chromatography (HPLC) as control, HbA1c for 200 samples of EDTA-K2 anti-coagulated whole blood were detected by immune fluorescence chromatography to synchronous blinded trial. Results As to the precise of immune fluorescence chromatography in the samples of 6% and 8%, values of coefficient of variation were 5.1% and 5.3%, respectively. The linear regression equation of immune fluorescence chromatography and HPLC was Y=-0.110+1.021X and the correlation coefficient was 0.982. 6.0% and 8.0% as the cut-off value, kappa values were 0.950 (P < 0.001) and 0.922 (P < 0.001), respectively. Conclusion Immune fluorescence chromatography and HPLC is consistent with detection of HbA1c, which can be used for clinical detection of HbA1c.

Objective To compare the clinical efficacy and safety of transurethral plasmakinetic resection of prostate (PKRP) and transurethral resection of prostate (TURP) for benign prostatic hyperplasia (BPH). Methods Two groups of BPH patients (78 patients in each group) were treated by PKRP and TURP,respectively. The clinical efficacy and safety indices were reviewed and compared for both intra- and inter-groups. Results In PKRP group,the operative time,intraoperative bleeding, the rates of postoperative temporary urinary incontinence (within 2 months) ,secondary hemorrhage (within 4 weeks),and urethral stricture (within 3 months) were ( 64?21) min, ( 247?84) ml, 26. 9% ( 21/78 ) , 1. 3% ( 1/78 ) and 2.6% (2/78) ,respectively; while in TURP group, these parameters were (78?18) min, (432?132) ml, 48.7% (38/78) , 10. 3% (8/78) and 12. 8% ( 10/78 ), respectively; there were significant differences between the 2 groups (P 0. 05). Conclusions PKRP and TURP have similar efficacy in the treatment of BPH,but PKRP is safer than TURP. Thus,PKRP is a better treatment option for BPH.
