Objective To evaluate the clinical benefits and safety of endoscopic thyroidectomy via bilat -eral-nipple approach and breast approach by comparison with conventional open thyroidectomy .Methods 59 pa-tients undergoing open thyroidectomy , 76 patients undergoing endoscopic thyroidectomy via breast approach , and 122 patients undergoing endoscopic thyroidectomy via bilateral-nipple approach were retrospectively analyzed . Patients'age, operation duration, intraoperative blood loss, the first day drainage volume after operation , postop-erative hospital stay , the incidence of complications , pain visual analogue score ( VAS) , postoperative satisfaction rate as well as the evaluation of cosmetic results were compared among different groups .Results No significant difference was observed in the intraoperative blood loss and the postoperative hospital stay among different groups . The operation duration and the first day drainage volume after operation in the endoscopic thyroidectomy groups ((103.5 ±26.2)min vs (108.1 ±23.9)min,(106.5 ±31.0)ml vs (117.4 ±38.8)ml)were significantly high-er than those in the open thyroidectomy group((65.3 ±22.4)min and (50.5 ±23.8)ml)(P<0.05, respective-ly).No significant difference was observed in the complication incidence among different groups .On the first day after operation, VAS of the endoscopic thyroidectomy groups (2.8 ±0.4 vs 2.9 ±0.4)was significantly lower than that of the open thyroidectomy group(3.8 ±0.6)(P<0.05, respectively), even though on the second and the third day no significant difference was observed among different groups .Besides, postoperative satisfaction rate and the evaluation of cosmetic results in endoscopic thyroidectomy groups were significantly higher than those in the open group(P<0.05, respectively).Furthermore, 90 days after operation, the satisfaction rate and the eval-uation of cosmetic results in the endoscopic thyroidectomy group through bilateral -nipple approach (96.7%,8.8 ± 0.9)were significantly higher than those in the endoscopic thyroidectomy group through breast approach (92.1%, 7.3 ±0.7)(P<0.05, respectively).Conclusions Endoscopic thyroidectomy is a feasible and safe procedure . Endoscopic thyroidectomy through bilateral-nipple approach has a higher long-term satisfaction rate as well as bet-ter cosmetic results , which is an ideal choice of thyroidectomy .

OBJECTIVETo explore gene expression of NANOG in T-cell acute lymphoblastic leukemia (T-ALL) cell lines and the effects of NANOG gene down-regulation on apoptosis of leukemia cells.

METHODSReal-time PCR (RT-PCR) and Western blot were used to detect the expression level of NANOG gene and protein in MOLT-4, CCRF-HSB2 and Jurkat cells. To test the efficiency of RNA interference, MOLT-4 cells were firstly infected by lentiviral vectors, which were successfully constructed with NANOG specific shRNA. NANOG expression levels were subsequently re-evaluated by RT-PCR and Western blot. The percentages of early apoptotic cells (Annexin V⁺/7-AAD⁻) and late apoptotic cells (Annexin V⁺/7-AAD⁺) were analyzed by flow cytometry. The expression of apoptosis-related genes was also detected.

RESULTSBoth NANOG gene and protein expression was positive in MOLT-4 and CCRF-HSB2 cells. The lentiviral vectors pLB-shNANOG-1, pLB-shNANOG-2, and pLB-sh control were successfully constructed, as evidenced by the viral titers (1.83-3.12)× 10⁸ IU/ml. The experimental data on infection of MOLT-4 cells with such lentiviral vectors revealed that both shRNA interfering sequences (shNANOG-1 and shNANOG-2) could stably down-regulate NANOG gene and protein expressions. The percentages of early apoptotic cells in groups of shNANOG-1[(8.06 ± 1.61)%]and shNANOG-2[(5.67 ± 1.59)%]were significantly increased as compared to that of MOLT-4 group[(1.13 ± 0.40)%]or sh-control [(1.15±0.49)%](P<0.05). However, no statistical difference among them was observed for late apoptotic cells (P>0.05). The gene expression of TP53, PMAIP1, and CASP9 of either shNANOG-1 or shNANOG-2 group was augmented as compared to that of MOLT-4 group or sh-control (P<0.05). Reversely, a significant down-regulation of Bcl-2 gene expression was observed (P<0.05).

CONCLUSIONNANOG can be expressed in various human T-ALL cell lines. Down-regulation of NANOG can trigger leukemia cellular apoptosis through mitochondria-dependent apoptosis pathway.

Objective To study the clinical, endoscopic and pathological features of gastrointestinal and mesenteric reactive nodular fibrous pseudotumor (RNFPT). Methods A retrospective analysis was conducted on data of 24 RNFPT patients in Nanjing Drum Tower Hospital admitted from October 2008 to June 2016. The clinical, endoscopic, pathological and immunohistochemical characteristics were analyzed. Results Among the 24 patients, 16 complained about discomfort in the upper abdomen and 10 had a history of surgery or trauma. Twenty-one had isolated masses and 3 had multiple masses, with diameter of 0. 5-4. 0 cm. Endoscopically, the tumors were mainly hard submucosal masses with broad base, and smooth surface with no mucosal bridge. Seventeen patients underwent endoscopic ultrasonography, which showed low echoes in lesions and nonuniform echoes partly. Among them, 13 lesions derived from muscularis, 4 others from submucosa. Microscopically, the tumors had clear boundary with no envelope, and most areas showed disorderly arranged spindle cells and extensively collagenous degenerated mesenchyma. The spindle cells had shuttle fibroblast-like morphology and elongated nucleus with no visible necrosis or mitosis. Inflammatory cells scattered between the tumor cells, and lymphoid follicles and calcium deposition could be seen in local areas. Immunohistochemically, SMA was focally positive in 7 cases and only 4 cases expressed CD117 scattered. Desmin, Dog-1, CD34, ALK-1 and S-100 were all negative, and Ki-67 proliferation index was lower than 1％. Conclusion RNFPT has diverse clinical manifestations, with a good prognosis and unlikely recurrences, and should be distinguished from spindle cell tumors.

Trichinosis is a global food-borne zoonotic parasitic disease caused by Trichinella spiralis(T.spiralis),which causes serious harm to animal production,and the public health safety of humans and animals.T.spiralis has a complex devel-opment history,and its entire life cycle is completed in the same host.To coexist with the host,it has evolved various immune escape mechanisms for avoiding immune clearance by the host,thus establishing long-term chronic infection.In this study,to aid in understanding the pathogenic mechanism of T.spiralis,the immune escape mechanism of Trichinella is discussed from three aspects:the molecular role of antigens in various stages,the immune regulatory effect on the host,and the formation of cysts to generate immune isolation.

·AIM: To evaluate the effect of bupivacaine in non-catheter infiltration anesthesia during vitretomy operation.·METHODS:Fifty-eight patients (58 eyes) with vitreous retinal surgery were selected. Patients were randomly divided into observation group ( 28 eyes ) and control group ( 30 eyes ) . The observation group were received non-catheter infiltration anesthesia. The control group were received traditional Sub- Tenon's block ( STB ) . Degree of pain, basic vital signs, the duration of anesthesia and analgesia grade were recorded and compared between two groups.·RESULTS: No significant difference was found in the 11-point numeric rating scale ( NRS - 11 scoring ) of anesthesia process, sclera incision, intraocular operation and the end of operation between two groups (P>0. 05). The difference were not significant in heart rate and blood pressure between two groups(P>0. 05). There was statistically significant difference in the duration of anesthesia between two groups (P<0. 05).·CONCLUSION: Both groups can provide the same anesthetic effect. Compared to STB, non - catheter infiltration anesthesia takes short time, and it is a safe and effective anesthesia methods. In addition, compare to the mixture of bupivacaine and lidocaine injection, bupivacaine injection can provide the same anesthetic effect.

Objective To examine the associations between season of birth and factors as age at menarche,age at menopause and reproductive span.Methods A total of 285 186 female from the China Kadoorie Biobank,with complete data on critical variables and had menarche at 9-18 years old,were included.A total of 132 373 female with natural menopause were included for the analysis on age at menopause and reproductive span.Multiple linear regression models were used to assess the associations of birth season and the age at menarche,menopause,and reproductive span.Subgroup analyses were performed on birth cohorts and urban/rural residence.Results Compared with the Spring-born (March,April,and May),participants who were born in Summer (June,July,and August),Autumn (September,October,and November),and Winter (December,January,and February)appeared late on both age at menarche and menopause.Multivariable-adjusted coefficients (95％ CI)appeared as 0.14 (95％CI:0.13-0.16),0.26(95％CI:0.24-0.27),0.10 (95％CI:0.08-0.12) for age at menarche respectively and 0.14 (95％CI:0.08-0.20),0.18 (95％CI:0.12-0.24),0.09 (95％CI:0.03-0.16) for age at menopause respectively.No statistically significant association was found between the season of birth and reproductive span.The association was consistent between urban and rural residents and across the birth cohorts.Conclusions female born in spring showed both earlier age on both menarche and menopause,compared to the ones born in other seasons.Our findings suggested that exposures in early life with some degree of seasonal variation might influence the development of female reproductive system.

Objective: To explore the evaluation of joint injury by HEAD-US-C (Hemophilic Early Arthropathy Detection with UltraSound in China, HEAD-US-C) in patients with moderate or severe hemophilia A treated with prophylaxis vs on-demand. Methods: The patients from June 2015 to July 2017 with moderate or severe hemophilia A were examined by ultrasound imaging of the elbows, knees and ankles; Meanwhile the HEAD-US-C ultrasound assessment scale and hemophilia joint health score scale 2.1 (HJHS2.1) were used to score the joint status. The correlation between the HEAD-US-C and HJHS score was performed in prophylaxis group and on-demand group patients, respectively. Results: A total of 925 cases of joint ultrasonography were conducted in 70 patients with moderate or severe hemophilia A. Among patients with moderate hemophilia, the median (IQR) of HEAD-US-C score and HJHS score in on-demand group were significantly higher than those in the prophylaxis group[1 (0, 6) vs 0.5 (0, 3) , z=0.177, P=0.046],[2 (0, 4) vs 2 (0, 3) z=0.375, P=0.007], even though there was no significant difference of the median (IQR) number of annualized target joints bleeding episodes between on-demand and prophylaxis groups[1 (0, 7) vs 1 (0, 5) , z=1.271, P=0.137]. Unlike in moderate cases, on-demand treatment group had more annualized target joints bleeding episodes than prophylaxis group among patients with severe hemophilia[3 (0, 8) vs 2 (0, 8) , z=0.780 P=0.037]. The prophylaxis group compared favorably with on-demand therapy group in terms of HEAD-US-C score[1 (0, 6) vs 4 (0, 7) , z=2.189, P=0.008], and HJHS score[2 (0, 5) , 4 (1, 6) , z=3646, P<0.001]for the severe hemophilia patients. The positive correlation between HEAD-US-C score and HJHS score was identified (P<0.05) , whether on-demand treatment or prophylaxis groups. The correlation coefficient between HEAD-US-C score and HJHS score in on-demand treatment and prophylaxis groups were 0.739 (95% CI 0.708-0.708) , 0.865 (95% CI 0.848-0.848) respectively, and 95% CI didn't overlap (P<0.05) , indicating that the correlation coefficient in prophylaxis group had stronger correlation than that in on-demand group. Conclusions: Clinical effects of prophylaxis were significantly better than those of on-demand treatment in patients with moderate or se-vere haemophilia A. HEAD-US-C scoring system could effectively evaluate joints damage in hemophilia A patients treated with on-demand or prophylaxis, companied by significantly positive correlation with HJHS clinical evaluation system, and provided objective index for clinical effect assessment.
