Objective To observe the clinical efficacy of acupoint thread embedding in preventing urinary retention after cervical cancer surgery.Method Fifty eligible patients were randomized into a treatment group and a control group, 25 cases each. The control group was given catheterization after gynecological surgery; the treatment group was intervened by thread embedding at Zusanli (ST36), Sanyinjiao (SP6), Yinlingquan (SP9), Guanyuan (CV4), and Shenshu (BL23) on the 7th day after the surgery in addition to the basic intervention given to the control group. The indwelling catheter was removed on the 14th day after the surgery, and the bladder function, urination, and residual urine volume were compared between the two groups.Result After the treatment, the bladder function in the treatment group was significantly better than that in the control group (P<0.05); the markedly effective rate of spontaneous micturition was 92.0% in the treatment group versus 72.0% in the control group, and the difference was statistically significant (P<0.05).Conclusion Early intervention with acupoint thread embedding after cervical cancer surgery can effectively decrease the incidence of post-surgery urinary retention, and it's easy-to-operation and worth application in clinic.

Objective To explore the effect of health education on the compiance and the knowledge level of the disease of patients with helicobacter pylori (Hp).Methods Totals of 300 patients with Hp were randomly divided into test group and control group by the date of examination.Test group received the system education such as aspectant explaining,offering health education prescription,circularly playing the kinescope of Hp and call on,while control group received the routine health education.all patients were investigated with the selfdesigned Hp questionnaire about the knowledge.Then,the compiance and the knowledge level of the disease of two groups were observed and compared.Results The awareness rate of test group and control group respectively was 98％ and 76％,there was significantly difference between two groups in the knowledge of route transmission,control measures,harm,therapeutic method,medicine use attention,reexamination time ( x2 =27.75,34.38,33.62,20.73,19.73,23.28,respectively; P＜0.01).The compiance of test group such as therapy,prevention,reexamination was significantly better than that of control group (x2=43.16,29.26,43.28,respectively; P＜0.01).Conclusions Implemention of targeted,systematic health education can improve the compiance of patients with Hp.

OBJECTIVETo investigate the heparitinase (HPA) expression and cell invasiveness in human ovarian cancer cell line SKOV3 during hypoxia, and explore their relationship with hypoxia inducible factor-1alpha (HIF-1alpha).

METHODSSKOV3 cells were incubated with normoxia, hypoxia, and hypoxia plus rapamycin, respectively. SKOV3 cells of hypoxia group were incubated in 5% CO2 + 1% O2. Cells in hypoxia plus rapamycin group were incubated with 10 ng/ml of rapamycin before cultured under hypoxic condition. Cells in each group were collected for analysis after incubated with hypoxia for 12, 24, and 36 hours, respectively. Western blotting and RT-PCR were performed to detect the expressions of HIF-1alpha and HPA. Cell invasiveness was measured by matrigel invasion assay.

RESULTSWestern blotting showed that the expression of HIF-1alpha significantly increased compared with normoxic group (P < 0.05). However, hypoxia had no obvious impact on HIF-1alpha mRNA expression. The expressions of HPA protein and mRNA of SKOV3 cells of hypoxia group were significantly higher than normoxic group (P < 0.05). The up-regulation of HPA expression in hypoxic group decreased after the utilization of rapamycin. The cell invasion of hypoxic group was significantly higher than that of normoxic group (P < 0.05); meanwhile, the expression of HPA was positively correlated with the invasiveness of SKOV3 cells (r = 0.9863, P < 0.05).

CONCLUSIONHypoxia may promote the expression of HPA and the invasiveness of SKOV3 cells through the HIF-1alpha pathway, which plays an important role in the pathogenesis of ovarian cancer.

Objective:To observe the clinical efficacy of fire-needle therapy in treating deglutition disorders due to pseudobulbar palsy in the remission stage of stroke.Methods:Sixty-two eligible subjects were divided into a fire-needle group and a rehabilitation group by a simple randomization method at a ratio of 1:1.The two groups received same basic intervention;in addition,the fire-needle group received fire-needle treatment,while the rehabilitation group received rehabilitation training.The two groups of subjects all received a 3-week treatment and were evaluated by the dysphagia severity rating scale (DSRS),modified Mann assessment of swallow ability (MMASA) and Kubota Toshio swallow test (KTST) before and after the intervention.The complications and adverse events occurred during the trial were recorded.The data were statistically analyzed.Results:At the third week,the DSRS,MMASA and KTST scores changed significantly compared with the baseline in both groups (P＜0.05),and the changes in the fire-needle group were more significant than those in the rehabilitation group (P＜0.05).The between-group comparison at the third week showed that the therapeutic efficacy in the fire-needle group was superior to that in the rehabilitation group (P＜0.05).Conclusion:Fire-needle therapy can obviously change the DSRS,MMASA and KTST scores in pseudobulbar palsy in the remission stage of stroke,and significantly enhance the therapeutic efficacy of the treatment of deglutition disorders in this stage.

A rapid ultra-performance liquid chromatography-electrospray ionization tandem mass spectrometric (UPLC-ESI-MS/MS) method is developed for the qualitative identification of constituents in the flower buds of seven Lonicera species. The optimal condition of separation and detection were achieved on an AcQuity UPLC BEH C18 column with a gradient elution with acetonitrile and 0.1% acetic acid within 17 min. Among the 33 constituents detected, 6 caffeoylquinic acids (including caffeic acid), 8 flavonoids and 8 iridoid glycosides were characterized based on their fragmentation patterns in collision-induced dissociation (CID) experiments and/or by comparison with standard compounds. In addition, to statistically establish the correlation and discrimination of the Lonicera species, principle component analysis (PCA) was applied in this study. Lonicera samples were divided into well-defined groups directly related to their species based on PCA in terms of the log transformed relative contents of the major caffeoylquinic acids (including caffeic acid) as the variables. All of results indicated that the method presented here is able to classify the sample species and to reveal characteristic details of the chemical constituents of different Lonicera species.

Objective To investigate the expression of Th17/Th1cells in peripheral blood and its relationship with rapid virologic response (RVR) to the therapy with pegylated interferon (PEG-IFN)combined with rib(a)ivirin (RBV) in patients with chronic hepatitis C (CHC).Methods Thirty one CHC patients treated with PEG-IFN combined with RBV were enrolled,and the demographic and clinical data including age,gender,body mass index (BMI),results of biochemical parameters in serum and the peripheral blood samples at baseline were collected. Eleven healthy volunteers were enrolled as control group.The RVR in 4th week were observed by prospective experimental research method. The ratio of CD3 +,CD8 -,IL-17 +,Th17 and CD3 +,CD8-,IFN-γ+,Th1in peripheral blood mononuclear cells (PBMCs) were detected at baseline by flow cytometry.Results Compared to the healthy control group,the level of Th1cells was decreased and the level of Th17 cells was increased in patients with CHC.In non-RVR group of CHC,compared to the healthy control group,the level of Th1cells was decreased significantly,and the level of Th17 cells was increased significantly ( P ＜ 0.05 ). Conclusions There was Th1/Th17 subgroups imbalance in no-RVR CHC patients treated with PEG-IFN combined with RBV,the level of Th1cells was reduced,and the level of Th17 cells was increased.The high level of TH17 cells and low level of Th1cells at baseline may not be conducive to the RVR.

Objective To investigate the position change of upper molars and incisors in order to evaluate the stability of posterior anchorage with the application of micro-screw implant. Methods Eight adult patients with severe maxillary protrusion were included. Upper first premolars were extracted and upper posterior anchorage was reinforced with micro-screw implant in all patients. Cephalometric and cast analyseswere carried out to record the position change of molar and micro-screw. Results During treatment the micro-screw implants kept stable in sagittal and vertical plane.Neither the mesial-distal movement nor the tipping of the upper molars during the treatment was statistically significant(P＞0.05).The edge of upper incisors was retracted by 6.86 mm and the tipping was reduced by 18.03°.The center of resistance was intruded by 3.28 mm on average. Significant change was observed(P＜0.01).Conclusions Micro-screw implant could provide good anchorage control in the orthodontic treatment.

OBJECTIVETo investigate the effects and related mechanisms of Tumstatin 185-191 as a single agent or in combination with cisplatin on proliferation and apoptosis in a cisplatin-resistant human lung adenocarcinoma cell line A549-DDP cells.

METHODSA549-DDP cells were treated with Tumstatin185-191 and cisplatin at varying concentrations. Cell viability was assessed by a modified 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. 50% inhibiting concentration (IC(50)) values of the chemotherapeutic drugs were analyzed by MTT assay. Cell apoptosis was measured by flow cytometry. The activation of Akt and ERK was evaluated by Western blotting.

RESULTSTumstatin185-191 inhibited the proliferation of A549-DDP cells and its IC(50) value was 80.25 micromol/L. After cotreatment with 20 micromol/L Tum185-191, the IC(50) value of cisplatin in A549-DDP cells reduced from 77.16 micromol/L to 57.97 micromol/L, the reverse index was 1.33, while with 40 micromol/L Tumstatin185-191 the IC(50) was reduced from 77.16 to 26.40 micromol/L and the reverse index was 2.92. The early apoptosis rate was 19.5% +/- 1.1% in the cotreatment group, while 13.3% +/- 1.5% in cisplatin group and 10.2% +/- 2.0% in Tum185-191 group (F = 4.09, P < 0.05). The levels of phospho-Akt (p-Akt) and phospho-ERK (p-ERK) in the A549-DDP cells were remarkably lower after treatment with Tumstatin 185-191. The Tumstatin 185-191 treatment alone or in combination with cisplatin had a similar effect on the protein levels of p-Akt and p-ERK in A549-DDP cells.

CONCLUSIONOur data suggest that Tumstatin185-191 may promote apoptosis, downregulate proliferation and partly reverse the drug resistance of A549-DDP cells to cisplatin. The effects induced by Tum185-191 may be mediated through inactivation of the Akt and ERK pathways.

OBJECTIVETo identify the phenotype and gene mutation in two Chinese pedigrees with hereditary protein C deficiency.

METHODSThe plasma level of protein C activity (PC: A) , protein C antigen (PC: Ag), protein S activity (PS: A), and antithrombin activity (AT: A) of the probands and their family members were detected using chromogenic assay and ELISA, respectively. All of the nine exons and intron-exon boundaries of protein C gene were amplified by PCR and analyzed by direct sequencing of the probands. Restriction enzyme site analysis was used to confirm the mutation.

RESULTSThe plasma PC: A and PC: Ag for proband 1 was 1.2% and 0, respectively. Compound heterozygous mutations, C(TGC)64W (TGG) and F(TTC) 139V(GTC) , were identified in her, the former being inherited from the maternal side and the later the paternal side. Further genetic analysis showed that her husband ( II 8) had the heterozygous deletion mutation (K150 or 151 Del) in exon 7, her daughter had the same heterozygous deletion mutation and a F139V. The plasma PC: A and PC: Ag for proband 2 was 50. 3% and 1.9 mg/L, respectively. He had the heterozygous Lys150 or Lys151 deletion mutation, which was inherited from his father. Polymorphisms of C/T at position - 1654, A/G at - 1641 , and A/T at - 1476A/T in the promoter region of protein C were confirmed in all members of the two pedigrees, of which, proband 2 had homozygous CC/GG/TT. The F139V mutation was confirmed by restriction enzyme site analysis and polymorphism for this mutation was excluded. PS: A and AT: A were in normal range for all members.

CONCLUSIONCompound heterozygous mutation C64W and F139V of protein C gene lead to type I hereditary protein C deficiency for proband 1. K150 or 151 deletion mutation and polymorphism of CC/GG/TT might lead to type I hereditary protein C deficiency for proband 2. C64W is a novel mutation for protein C gene. F139V and K150 or 151 deletion mutation are reported for the first time in China.

OBJECTIVETo summarize the clinical experience with multi-channel cochlear implantation in patients with inner ear malformations and evaluate and the outcomes of speech rehabilitation.

METHODSA retrospective study was conducted in 295 patients receiving cochlear implantation from 1998 to 2007, including 25 patients with large vestibular aqueduct syndrome (LVAS), 9 with Modini malformation, and 5 with common cavity deformity. All the patients received the Nucleus24 cochlear implants. In LVAS cases, 4 had Nucleus 24R (ST) implants, 8 had Contuor implants, 10 had Contuor Advance, and the remaining cases used Nucleus24(M) straight-electrode implants.

RESULTSSevere gusher appeared in 3 cases of LVAS, and perilymph fluctuation were seen in other 15 cases. Four patients with Mondini malformation and 2 with common cavity malformation also experienced severe gusher, but the electrodes were inserted smoothly in all the patients without postoperative facial paralysis or cerebrospinal fluid leakage. The hearing threshold in these patients was similar to that in patients with normal cochlear structure. After speech rehabilitation for over 6 months, the abilities of speech discrimination and spoken language improved in all the cases in comparison with the preoperative lingual functions.

CONCLUSIONMulti-channel cochlear implantation can be performed in patients with inner ear malformation, but should not be attempted in patients with poor cochlear and cochlear nerve development. A comprehensive pre-operative radiographic and audiological evaluation is essential.
