Objective To evaluate the effectiveness of tobacco control interventions among employees in centers for disease control and prevention (CDC) in Hebei Province. Methods Tobacoo control interventions, including health education, Quit and Win competition, and founding smokeless CDC, were carried out in CDC system in Hebei Province from May 2006 to June 2008. Surveys on smoking rate of employees and on average cigarette quantity consumed by male employee smokers were conducted at the beginning and the end of the interventions. Results In 2006, 9 931 employees in 174 centers at provincial, city, county level in Hebei Province participated in this study. The overall smoking rate was 25.69%. Male employees had a higher smoking rate (51.28%) than the females (0.68%). The smoking rate of male employees was 50.92%, 49.48% and 51.72% for provincial, city and county CDC levels, respectively. The average cigarettes consumed by one smoker in one day were 15.0. In 2008, 9 139 employees in 189 centers participated in this study. The overall current smoking rate was 25.07%. The smoking rate was 52.26% and 0.43% for males and females, respectively. The smoking rates of male employees in provincial and city CDCs were 43.93% and 46.18%, significantly lower than those in 2006. The smoking rate of male employees in county CDCs was 53.98%, much higher than that in 2006. The average cigarettes consumed by one smoker in one day in 2008 were 12.4, significantly less than that in 2006. The current smoking rate of male employees in smokeless CDCs was 48.0% , significantly lower than 56.9% in non smokeless CDCs. Conclusion Male employees in Hebei Province CDC system had a high smoking rate. Tobacco control interventions play a role in reducing smoking rate and cigarettes consumption.

Objective To explore the curative effects of microsurgical clearance for supratentorial hypertensive intracerebral hemorrhage. Methods A retrospective analysis of clinical data of 30 cases of supratentorial hypertensive intracerebral hemorrhage in our hospital from January 2010 to January 2013 was carried out. According to the head CT images, the position of incision was determined. Under orotracheal intubation general anesthesia, a bone flap craniotomy was performed. A cortex fistula 2-3 cm in length was made. Then by using an automatic retraction device, the hematoma was revealed from the shallower to the deeper, and microscopic clearance of hematoma was completed. Results All the 30 cases of operation were successful. Re-examination of head CT scans on the first postoperative day showed hematoma was completely removed in 14 cases, was 90%cleared in 11 cases, and 80%in 5 cases. Four patients died within 4 weeks after operation (13.3%):2 patients died of cerebral hernia caused by brainstem function failure, 1 patient died of lung infection, and 1 patient died of multiple organ failure. The postoperative survival rate was 86.7%.The ADL grade assessment 3 months after operation showed gradeⅠin 7 cases, grade Ⅱin 9 cases, grade Ⅲin 6 cases, grade Ⅳ in 3 cases, and grade Ⅴin 1 case. Conclusion Microscopic hematoma clearance and open haemostatic intervention has advantages of little brain tissue damage, good haemostatic results, and satisfactory efficacy.

Each woman of childbearing age has the right to enjoy reproduction, including cancer patients. Breast cancer is the most common malignant tumor in women. Many factors led to the significant increase of young patients with fertility problems, and the majority of doctors neglected their reproductive requirements in clinical work. Given the comprehensive treatment, almost every young patient suffers from fertility decline and even loss. Patients who chose to get pregnant also harbor a variety of concerns. This paper reviews the effects of comprehensive treatment on fertility, preservation strategies, pregnancy and prognosis, optimal time for pregnancy, and other aspects and provides guidance for young breast cancer patients in their reproduction choices.

Objective To investigate the effect of nerve growth factor (NGF) on recuperate of optic nerve after contusion by clamping in adult rabbits. Methods Sixteen adult rabbits were randomly divided into NGF and the control group with 8 rabbits in each group. After the optic nerve of the right eyes was clamped,tissue engineering nerve containing (0.06 ml) NGF(concentration: 5?10~(-4) g/L, NGF group) and 0.06 ml of PBS (control group) was immediately transplanted into the injured eyes respectively, and 0.02 ml NGF(concentration: 5?10~(-4) g/L, NGF group)and 0.02 ml of PBS (control group) were injected into the vitreous of right eyes respectively. Flash visual evoked potential (FVEP) test was performed on the eyes 1 day, 2 weeks and 8 weeks after the injury. The number of retinal ganglion cells (RGCs) and changes of optic nerves were observed by light microscopy and electron microscopy at the 8th week after contusion,and a computer-image-analysis system was used to count the optic nerve axons. Results The ratio of amplitude of FVEP of the injured and healthy eyes was 0.765?0.150 in NGF group and 0.494?0.108 in the control at the 2th week after injury with a significant difference between the two groups (P

Objective To explore the related factors to influence the curative effect of focused ultrasound treatment for non neoplastic epithelial disorders of vulva. Methods A total of 382 patients with non neoplastic epithelial disorders of vulva were included in this study and treated by focused ultrasound. During and after the treatment, the symptoms and physical signs of the subjects were observed, and the efficacy was evaluated. We analyzed the relation between pathologic type, age, course, area, or itch degree and curative effect. Results Symptoms of all patients were relieved, and appearance and color of the vulva became normal after the ultrasound treatment, with a total effective rate of 99.74%. The cure ratios of patients with different pathologic types, ages, courses, areas, and itch degrees were significantly different (χ2=9.58, P<0.01; χ2=22.385, P<0.01; χ2=32.260, P<0.01; χ2=57.99,P<0.01; χ2=42.13,P<0.01, respectively). Conclusion Focused ultrasound treatment is safe and effective for the nonneoplastic epithelial disorders of the vulva and the efficacy is associated with the pathologic type, age, course, area, and itch degree.

Objective To summarize the clinical characters,diagnosis and surgical treatment of primary hyperparathyoidism (PHPT).Methods The diagnosis,treatment and efficacy of 35 cases of PHPT were retrospectively reviewed.Results PHPT presented a variety of clinical manifestations,and occoured to different age groups without significant gender differences.All the 35 cases had elevated blood calcium and PTH.All patients underwent preoperative ultrasonography and 99Tcm-MIB imaging,and the positive rates were 68.6％ and 97.1％ respectively.34 patients received surgical treatment,among whom 30 cases had parathyroid adenoma,1 case had parathyroid hyperplasia and 3 cases had parathyroid carcinoma.Through operation,31 cases were cured,2 cases improved,and 1 case of parathyroid carcinoma suffered from lung metastasls.Conclusions PHPT can be diagnosed according to co-elevated serum calcium and PTH.Ultrasonography combined with 99Tcm-MIB imaging should be recommend for preoperative localization.The main cause of PHPT is solitary parathyroid adenoma.PTPT can be cured by surgery.Minimally invasive parathyroidectomy with accurate location is an efficient surgical strategy,and the prognosis is favorable.

Objective To study the method of solving the complications of large allograft including resorption, nonunion and refracture by means of vascularization and the way of improving bone healing. Methods The bone defect longer than 10 cm of limbs were found in 21 cases, plate or external fixator were used to fix allograft bone, and then vascularied autologous bone or periosteum were transplanted or inserted to the massive allograft In order to vascularizate allograft, improve bone healing and prevent complications of bone resorption and osteolysis. 4 cases were implanted by local vascular bondle in one end. 4 cases were transplanted vascular iliac bone into middle part the allograft bone, 2 cases were into one end. 2 cases were transplanted by vascular fibular bone. 6 cases were used vascular periosteum. 3 cases were used combined methods. Results Twenty-one cases with 10 cm or more bone defect in this group were treated by the method above. 14 cases were achieved primary healing, 6 were healing by farther operation, 1 failure. Complications were found in 7 cases, 4 occur infection in all. All were achieved satisfactory function and outlook by follow-up.

Objective To investigate the correlation of plasma interleukin ( IL)-17 level and IL-17 receptor (IL-17R) expression in the thymus of patients with myasthenia gravis (MG).Methods The blood samples of 63 patients (38 with glucocorticoid treatment, 25 with thymus removal) who admitted to Henan Provincial People′s Hospital between 2010 and 2014 were collected at three different stages: pre-treatment, 1 week post-treatment and 1 month post-treatment.The blood samples of 42 healthy controls were also collected.Enzyme linked immunosorbent assay was used to evaluate the levels of IL-17 in plasma.Twenty-five thymus tissues from MG patients and another 12 thymus tissues from patients with congenital heart disease who had surgery therapy were also collected.Reverse transcription polymerase chain reaction was used to evaluate the mRNA levels of IL-17R.The possible correlation between the expression of IL-17 and IL-17R with MG was analyzed.Results Before treatment, the levels of IL-17 in the plasma were much higher in all the MG patients ( both ocular and generalized) when compared to the healthy controls ( controls (3.2 ±0.7) pg/ml, MG patients (8.5 ±1.7) pg/ml, t =2.450, P <0.01; generalized type patients (9.7 ±1.4) pg/ml, t =2.532, P <0.01).In the patients with glucocorticoid treatment, IL-17 levels began to reduce after 1 week treatment and a statistically significant difference was found when compared to the pre-treatment samples (pre-treatment (8.3 ±1.2) pg/ml, 1 week after treatment (6.3 ±0.7) pg/ml, t=2.052, P<0.05) and healthy controls (t =1.933, P<0.05).One month after the glucocorticoid treatment, the levels of IL-17 decreased to the normal level (1 month after treatment (3.9 ±0.6) pg/ml, t=2.630, P <0.01, compared to the pre-treatment; t =1.395, P >0.05, compared to the healthy controls).In the surgery therapy cases, the IL-17 levels were also reduced after the thymus removal ( pre-surgery (8.8 ±1.4) pg/ml, 1 week after surgery (5.3 ±0.7) pg/ml, t=1.950, P<0.05;1 month after surgery (3.0 ±0.4) pg/ml, t=2.683, P<0.01).In the thymus tissues of the MG patients, the mRNA levels of IL-17R were much higher than that of the controls ( relative level 2.31 folds, t =2.682, P <0.01).Meanwhile, a positive correlation was found between the plasma IL-17 levels and the relative IL-17R levels in thymus tissues ( r =0.945 4, P <0.01 ).Furthermore, IL-17 was positively correlated with quantitative myasthenia gravis scores (QMGS) either pre-treatment (r =0.798 1, P <0.01) or post-treatment (r=0.906 5, P<0.01).And IL-17R was positively correlated with QMGS pre-treatment (r=0.775 5, P<0.01).Conclusions IL-17 is increased in the plasma of MG patients (both ocular and generalized) , and is decreased upon the glucocorticoid treatment or surgery therapy, suggesting that it can be used as a parameter to determine the therapeutic effects.IL-17R is increased in the thymus tissues of MG patients, suggesting that it can potentially be used as a pathological diagnosis parameter.

OBJECTIVE: To investigate the expression and significance of vascular cell adhesion molecule-1 (VCAM-1) and P-selectin in hypopharyngeal carcinoma, and explore the relationship of VCAM-1, P-selectin and microvessel density (MVD). METHOD: Expression of VCAM-1 and P-selectin were detected by immunohistochemistry staining in 40 specimens of hypopharyngeal carcinoma and 10 specimens of normal mucosa of oral pharynx. MVD was assessed based on the expression of CD34. RESULT: VCAM-1 and P-selectin were detected in 26 out of 40 (65%) and 29 out of 40 (72.5%) respectively in hypopharyngeal carcinoma, but none that in normal mucosa (P<0.01). MVD in hypopharyngeal carcinoma was higher than that in normal mucosa and it was related to lymph node metastasis. MVD level was significantly higher in VCAM-1 and P-selectin-positive specimens than in negative ones (P<0.01), which also positively correlated with the expression of VCAM-1 and P-selectin (P<0.01). The expression of P-selectin positively correlated with VCAM-1 in hypopharyngeal carcinoma specimens with lymph node metastasis. CONCLUSION The higher expression of VCAM-1 and P-selectin play key roles in the invasion and metastasis of hypopharyngeal carcinoma and were correlated with vascularization.
