Translationally controlled tumor protein(TCTP)is a highly conserved and homologous protein that is widely expressed in all eukaryotic organisms and regulated at both the transcriptional and the translational level. TCTP participates in the regadation of cell cycle and proliferation, anti-apoptosis, and tumor reversion in tumor; it also correlates with ehemo-resistance. It may become potential targets of anti-tumor therapy and tumor reversion and provides a novel ideal for cancer therapy.

Objective To analyse the antibiotics susceptibility result of Neisseria gonorrhoeae(N.g) isolates.Method 95 strains of N.g were performed the in-vitro susceptibility test.MICs of penicillin, tetracycline, ciprofloxacin, levofloxacin, ceftriaxone, cefotaxime, cefepime, and spectinomycin were determined by agar dilution.Results Almost all of the N.g strains were susceptible to the first-line antibiotics used for treating the infection. The resistance rate to ciprofloxacin, tetracycline and penicillin were 100%, 78.9% and 68.4% respectively.Conclusion Although N.g is susceptible to first-line antibiotics used for treating the infections at the clinics, the situation of resistance to penicillin, tetracycline and ciprofloxacin is very serious.

Background Although great advances have been made in prevention and treatment of CVD through drug therapies and other procedures,diet and lifestyle modification remain the foundamental aspects in clinical inter vention for prevention and treatment of hypertension.Objective The purpose of this research is to investigate the impact of variour dietary patterns on traditional cardiovascular risk factors in essential hypertensives in Beijing area. Food frequency questionnaire (FFQ) survey was carried out in a cohort of 424 patients of hypertension.Methods All participants completed an FFQ.Baseline clinical data (height,weight,waist circumference and biochemical da- ta) were collected by physical examination and biochemical assay.According to their dietary patterns,three dietary pattern were delineated:vegetarian diet(n=95),meat dominant diet(n=133) and balanced diet(n=196).Clinical and biochemical data were compared between them,and analyzed by multivariate logistic regression models.Results 1)The morbidity of obesity in meat dominant people was significant higher than vegetarians (46.6% vs 21.7%,P

Objective To study the effects of previous analgesia of acupuncture on patients with the mixed hemorrhoid surgery pain.MethodsA total of 70 patients with mixed hemorrhoid treated with “Milligan-morgan hemorrhoids” were randomly divided into treatment group and control group, 35 patients in each group. The treatment group was treated 30 min prior to the surgery with needling and manipulating Baliao, Chengshan, Hegu every five minutes until the operation, while the control group was not treated before the operation. The patients were assessed by Visual Aualogue Scale and self-reporting Inventory.ResultsAfter the operation, the treatment group was significantly better than the control group in the outcome index of beginning time of pain (14.3 ± 4.9 hvs. 4.2 ± 2.3 h, Z=-5.666,P<0.01) and peak time of pain (17.3 ± 4.5 hvs. 6.0 ± 2.9 h,Z=-5.581,P<0.01).

Background The study on normal stem cell markers provides a new way of thinking of that pathogenesis of cancer research and looking for specific markers of cancer stem cells.Importin13 (IPO13) is a novel nucleus-cytoplasm transport receptor protein of importin β family,the study on the biological behavior of IPO13 in ocular tissue and limbal neoplasms is lacking.Objective This study was to investigate the differential expression of IPO13 and p63 in human benign and malignant conjunctiva-cornea neoplasms.Methods The specimens of normal donor limbal and conjunctival tissues (6),conjunciva-cornea papilloma (CCP) (6) and conjunctiva-cornea intraepithelial neoplasia(CCIN) (6)were collected from Xiangya Hospital of Center South University.The expressions of IPO13 and p63 in the corresponding tissue were qualitatively and quantitatively detected using immunochemistry.The A values of IPO13 and p63 positive response were calculated and compared among the 3 types specimens.Results The immunohistostaining on frozen sections showed that IPO13 was expressed in nuclei of basal cells of limbal and conjunctival epithelium and the cellular nuclei of basal cells and suprabasal cells of CCP and CCIN epithelium.The A values of IPO13 positive expression were 1687± 1014,3546± 1375 and 7635 ±2854 in the normal limbal specimen,CCP and CCIN,respectively,showing a significant difference among them (F =7.23,P＜0.05),and the A value was higher in the CCP and CCIN than that in the normal limbal tissue (q =4.02,5.13,P＜0.05),and that in the CCIN was significantly elevated in comparison with CCP(q =3.45,P＜0.05).p63 was expressed in nuclei of basal cells and suprabasal of limbal,conjunctival and CCP epithelium,and was expressed in nuclei of the entire CCIN epithelium.The expressions of p63 in the normal conjunctiva-cornea tissue,CCP and CCIN were 2110± 1229,3966± 2129 and 6650± 2136 respectively,with significant difference among the three different specimens (F =6.17,P＜ 0.05),and the A value of p63 positive expression was significantly elevated in the CCP and CCIN compared with normal limbal specimen (q =4.33,5.01,P＜0.05),and that in the CCIN was significantly elevated in comparison with CCP(q=3.83,P＜0.05).Conclusions IPO13 is more specifical in marking the poorly differentiated cells in limbal epithelial proliferative lesions than p63.Compared with the normal limbal specimen,the expressions of IPO13 and p63 in CCP and CCIN specimens gradually upregulat,which suggests that IPO13 and p63 may play a positive regulatory role in conjunctiva-cornea proliferative lesions.The differential expression of IPO13 and p63 is predominant between benign and malignant limbal epithelial proliferative lesions,indicating that IPO13 and p63 may play an important role in regulating the abnormal proliferation and differentiation of limbal epithelial proliferative lesions.

AIM: To analyze the direction and degree of static cyclotorsion component (SCC) and dynamic cyclotorsion component (DCC) in corneal refractive surgery.
METHODS:Retrospective analysis. Totally 130 patients (260 eyes) with corneal refractive surgery in our hospital, according to the operation method were divided into femtosecond laser - assisted laser in situ keratomileusis (FS-LASIK) group and T-photorefractive keratectomy (T-PRK) group, the differences of the parameters of the two groups were compared; the differences of SCC success rate, SCC, DCC, and the eyeball rotation direction were compared between the two groups; correlation analysis on SCC, DCC and the parameters of postoperative patients were performed.
RESULTS: High order aberrations and spherical aberration in the T-PRK group after operation was higher than those of FS - LASIK group, and the difference was statistically significant (P<0. 05); in T-PRK group SCC in the operation was successful in 98 eyes, the success rate was 81. 7%; in FS-LASIK group SCC in the operation was successful in 82 eyes, the success rate is 58. 6%, the difference of SCC success rate between the two groups was statistically significant ( P < 0. 05 ); SCC in T - PRK group was 3. 52o ±2. 17o and FS-LASIK group was 3. 49o ±2. 26o, there was no significant difference (P>0. 05); DCC in T-PRK group (2. 86o±1. 14o) was higher than that of FS-LASIK group ( 2. 17o ± 1. 09o), and the difference was statistically significant (P<0. 05). There was no statistical difference in the direction of rotation of the eyeball in operation between the two groups (P>0. 05). The SCC of subjects in operation was positively correlated with UCVA, BCVA, spherical equivalent refraction and high order aberrations ( P < 0. 05 ); the DCC of subjects in operation was positively correlated with UCVA and high order aberrations (P<0. 05).
CONCLUSION: The success rate of SCC in T - PRK surgery is higher than that in LASIK, DCC in T - PRK surgery is higher than that in LASIK, and accurate measurement of SCC and DCC can be effective to compensate for it.

Objective To explore the correlative factors and management of secondary high intraocular pressure(IOP) after vitreoretinal surgery for proliferative diabetic retinopathy(PDR). Methods The data of 51 patients(54 eyes) with PDR after vitreoretinal surgery were collected.The incidence of secondary high IOP was obtained,and the correlative factors leading to high IOP were analysed.Besides,the therapeutic effects of management were observed. Results Twenty-six patients(26 eyes) experienced postoperative high IOP,with the incidence of 48.15%(26/54).It was revealed that the preoperative retinal detachment,the combined performance of crystal phacoemulsification,the practice of intraocular tamponade and the postoperative posterioruveitis were related to the occurrence of high IOP(P

Objective To analyze the risk factors of central compartment lymph node (CCLN)metastasis in papillary thyroid carcinoma(PTC) without clinically suspected cervical lymph node metastasis (cN0).Methods Clinical data of 272 PTC (cN0) patients who underwent radical thyroidectomy and CCLN dissection between January 2008 and December 2012 in Huashan hospital were retrospectively analyzed.Patients were divided into CCLN positive group (115 cases)and CCLN negative group(157 cases) according to postoperative pathology.Chi-square test,wilcoxon test and multivariate logistic regression analysis were used to analyze risk factors.Results CCLN metastasis of papillary micro thyroid cancer (PMTC) and papillary thyroid cancer (PTC) was 34.9％ and 48.3％,respectively.Tumor size (x2 =10.26,P ＜ 0.01),position(x2 =13.87,P ＜ 0.01),capsular invasion(x2 =20.19,P ＜ 0.01),multifocal PTC(x2 =7.42,P ＜ 0.01) and unmicro-carcinoma (x2 =5.12,P ＜ 0.05) were significantly correlated to lymph node metastasis.Middle area or lower pole of thyroid carcinoma,capsular invasion and multifocal PTC were independent risk factors of CCLN metastasis in PTC.Conclusions The cN0 PTC has a high rate of pathological CCLN metastasis,it is imperative to conduct thyroidectomy with ipsilateral level CCLN dissection in PTC patients.
