In non-prescription medicines, The rate of pregnant and lactating women to use the medicine circumstance marked was 46.23%, 53.77% have never carried on to mark. CONCLUSION: The contents of pregnant and lactating women medication are far from perfect, Which should draw attention to better management.

Objective To explore the effect of physical condition on autonomous social participation function in stroke patients. Meth-ods A survey was conducted on 283 cases of stroke patients from October, 2014 to September, 2015. They were tested with General Situa-tion Questionnaire, Disease Status Questionnaire, Impact on Participation and Autonomy Questionnaire (IPA), Chinese Stroke Scale (CSS), and Mini-Mental State Examination (MMSE). Results Multivariate regression analysis showed that age, scores of MMSE and CSS, and physical disabilities were the factors related with autonomous social participation function in stroke patients (t>2.513, P<0.05). Conclusion It is needed to prevent and treat the complications of stroke early, which may contribute to the improvement of autonomous social participa-tion in stroke patients.

ObjectiveTo retrospectively analyze the relationship between clinicopathological,biological characteristics and the outcome of renal cell carcinoma(RCC) and evaluate the risk factors related to metastasis in young patients.MethodsThe data of 83 RCC patients younger than 40-year-old, treated from January 1986 to December 2007 in Tianjin Cancer Hospital,were analyzed retrospectively.The complete follow-up data of the 83 cases were collected.The operative methods included partial and radical surgery.Clinical staging were consistent with the 2004 UICC TNM classification criterion.The histological sections were reviewed.Various biological factors including VEGFR-1, VEGFR-2, VEGFR-3, PDGFR-α, PDGFR-β, c-kit and PCNA were tested by immunohistochemistry staining.The adjuvant radiation therapy, chemotherapy and immunotherapy after operation were carried out on the basis of pathological and biological features.The 83 cases were divided into two groups according to metastasis and non-metastasis status within 5 years.The prognosis related factors including clinical factors, pathological and biological factors were evaluated.Chi-square test was used for the analysis of 5-years metastasis status; and multivariate analysis was carried out using Cox proportional hazards models to assess the independent effect of the metastasis factors (the test standard α = 0.05).ResultsThe 5-year follow-up data showed that the metastasis rate in the 83 cases was 16.87％ (14/83).The Chi-square test results indicated that the patients with clinical stage Ⅲ and grade 3 had the highest metastasis rate (57.14％ and 78.57％respectively,x2 =38.042, x2 = 9.820; Ps ＜ 0.01) .The VEGFR-3 and PCNA positive expression rates were 92.86％ and 85.71％ respectively in metastasis group.The metastatic risk of early stage patients was 3.444 times as much as the advanced stage patients.ConclusionThe young patients with clinical advanced renal cell carcinoma had worse outcome.The stage,grade, VEGFR-3 and PCNA expression were the risk factors correlated with the metastasis risk for young RCC patients.TNM stage was an independent predictive risk factor of metastasis in young patients.

Objective Currently, the effect of hydrogen peroxide solution( H2 O2 ) flush on the recovery of peripheral nerve injury are still undetermined. This study aims to explore the effects of different H2 O2 flushing time course on recovery of peripheral nerve injury during surgical debridement. Methods 18 New Zealand male white rabbits were randomly divided into isotonic saline group( isotonic saline flush) , H2 O21 min group ( hydrogen peroxide solution flush 1 min + isotonic saline flush) , H2 O23 min group ( H2 O2 flush 3 min + isotonic saline flush. Each group has 6 rabbits. We established rabbit sciatic nerve injury model. After 12 weeks, we executed the animals, drew materials at the suture nerve, detected motor nerve conduction velocity and observed pathological HE staining, as well as measuring the sciatic nerve function indexes( SFI) of rabbits at the 8th and 12th week, respectively. Results Nerve conduction velocity in H2O21min group and isotonic saline group[(25.89±1.42), (26.46±1.67) m/s] were higher than that in the H2O23min group[(23.80±2.91)m/s](P<0.05). Pathological section shows that the isotonic saline group has a better sheathstructure, nerve fibers structure damage is not obvious and myelin degeneration degree is mild in H2 O21 min group. blurred sheath structure and myelin axons obvious deformation in H2 O23 min group. 8 weeks and 12 weeks after operation, SFI in isotonic saline group [(-43.00±0.82), (-39.17±0.91) m/s] was significant higher than H2O21 min group [ (-49.79±1.47), (-46.60±0.79) m/s] and H2O23min group [(-51.66±1.27), (-46.39±0.94) m/s], thedifference was statistically significant (P<0.05). SFI in group of H2O21min [(-49.79±1.47)m/s] was higher than group og H2O23 min [(-51.66±1.27) m/s][P<0.05]. Conclusion H2O2 solution has side effect on the recovery of damaged peripheral nerve inju-ry and with prolonging the H2 O2 flushing time, the damage of peripheral nerve can be aggravated. So in the process of clinical surgical debridement, under the premise of guaranteed sterilization the time of H2 O2 flush should be shortened as far as possible.

Objective To evaluate the treatment of advanced endometrial cancer with californium-252 brachytherapy. Methods 21 cases of endometrial cancers who had not received any treatment were diagnosed as in the stages Ⅰ～Ⅳ according to the criteria of FIGO. Treatment schedule included: 252Cf brachytherapy, 8～12Gy/fraction/week, the total dose of reference point A was 35～45 Gy and total dose of reference point F was 35～50Gy in three to four implant sessions. On the second day after 252Cf therapy, the whole pelvis was treated with 6MV X-ray external beam radiotherapy, 200 cGy per fraction, 4 times per week. The total dose of external beam radiotherapy was 45 to 50 Gy (the middle of pelvis was shielded with 4cm of lead), and the total treatment time was 5～6weeks. The recent therapeutic effect and complications were observed. Results The average time of complete tumor regression was 25 days, the local control rate was over 90%; the late radioactive complications of bladder and rectum was low during the 5-year follow-up period. Conclusions Combined californium-252 brachytherapy and high energy X-ray external beam radiotherapy may be safe and effective on advanced endometrial cancer.

Objective To research the early effect and side effect on the radiotherapy of nasopharyngeal carcinoma patient using IMRT compared with conventional radiotherapy. Methods Seventy eight nasopharyngeal carcinoma patients were divided into IMRT group (38 patients) and conventional radiotherapy group (40 patients). After CT-sim, the radiation oncologist and physician delineated the outline of GTV, CTV, parotid gland, spinal cord and brain stem. The receiving volume of parotid, spinal cord and PTV was respectively calculated by using inversing plan. Face-neck, supracalvicular field, amte-aural field and postaural field were adopted to receive electrons during conventional radiotherapy. Seven to nine conformal fields including 80-100 sub-fields were adopted during IMRT. The reaction of skin, parotid (xerostomia) and oral mucosa were recorded during radiotherapy. Results The nasopharyngeal and para-nasopharyngeal lesions regressed completely after radiotherapy. The volume received by the parotid, spinal cord and PTV was 30%?4.8, 56%?6.7, 95%?8.6, 92%?8.1 respectively in IMRT group, and 98%?9.4, 56%?10.7, 100%?9.7, 99%?9.5 respectively in conventional radiotherapy group. The received volume of parotid in IMRT group was significantly lower than in conventional radiotherapy group. The reaction of skin was grade I in IMRT group and grade II, III in conventional radiotherapy group. The reaction of parotid (xerostomia) was grade I and II in IMRT group and grade II and III in conventional radiotherapy group. The reaction of oral mucosa was grade I to II in IMRT group and grade II and III in conventional radiotherapy group. The reactions of skin and parotid (xerostomia) were lighter in IMRT group compared with those in conventional radiotherapy group. The time of radiotherapy was 45?4.4 days in IMRT group and 51?5.3 days in conventional radiotherapy group respectively. Conclusion The radiotherapy using IMRT regime can decrease the reaction of parotid (xerostomia) and skin to complete the radiotherapy course of nasopharyngeal carcinoma patients. Moreover, it can increase the life quality in nasopharyngeal carcinoma patients after radiotherapy and also shorten the time of radiotherapy.
