Objective To investigate the therapeutic mechanism of bazedoxifene, the third-generation selective ER modulator (SERM), on endometriosis lesions in a rat model. Methods Endometriosis was induced by transplanting pieces of endometrium from other syngeneic rats that were as donors onto the subcutaneous of other unmated female rats. The rats with successful ectopic implants were divided into two groups:control group (n=10) and bazedoxifene group (n=10). The macroscopic morphology, volume, histopathology of ectopic implant and rats uterine wet weight were determined before and after the treatment. Expression of proliferation cell nuclear antigen (PCNA), ER and PR in the eutopic endometrium and endometriosis lesions detected by immunohistochemistry in the two groups. Results (1) The gross morphology and histological changes of endometriosis lesions in rats after treatment: compared with the control group, it was obviously depauperated and had more less glands and blood vessels in the stroma. (2) The change of rats′weight, the volume of endometriosis lesion before and after treatment and rats uterine wet weigh after treatment respectively in the control group and the bazedoxifene group:rats′ weight were respectively before treatment: (201±17) g, (202±18) g, that were respectively after treatment: (266±16) g, (261±16) g, which showed no significant difference between two groups before and after treatment (P>0.05). The volume of ectopic implant before treatment were respectively (85±17) mm3, (85±12) mm3, and showed no significant difference between two groups;that were respectively (48±11) mm3, (24±9) mm3 afte rtreatment, which was significantly decreased compared with the control group (P<0.05). Rats uterine wet weight after treatment were respectively:(0.77±0.16) g, (0.45±0.18) g, and was significantly reduced compared with the control group (P<0.05). (3) The protein expression levels of PCNA, ER and PR in the endometriosis lesions after treatment were respectively 0.282 ± 0.044, 0.51 ± 0.06, 0.49 ± 0.05 in the control group, 0.191 ± 0.020, 0.23 ± 0.03, 0.48 ± 0.06 in the bazedoxifene group; that in eutopic endometrium were respectively 0.369 ± 0.081, 0.56 ± 0.08, 0.56 ± 0.10 in the control group, 0.211 ± 0.037, 0.27 ± 0.05, 0.54 ± 0.08 in the bazedoxifene group;the protein expression levels of PCNA and ER in endometriosis lesions and the eutopic endometrium were significantly decreased in the bazedoxifene group compared with the control group (P<0.05), but the protein levels of PR in endometriosis lesionsand and the eutopic endometrium were not significantly altered by treatment (P>0.05). Conclusion Bazedoxifene could obviously reduce the size of endometriosis lesions, the mechanism may be related with suppressing estrogen-induced proliferation, the expression of ER and direct ER antagonism by this SERM.

Around the world, the supply of health services faces challenges, especially in developing nations that suffer from inadequate infrastructure and aging equipment, frequent shortages of medicine and supplies, and low capacity and efficiency of primary health care. At present, more and more governments adopt public-private partner-ships to achieve public policy goals. Among those, Brazil, South Africa, and India have made greater achievements in changing the roles of local government, increasing the supply of primary health care and health care quality, pro-moting health care equality, meeting the needs of multi-level medical services, and promoting health capabilities by using public-private partnerships. This paper provides an overview of public-private partnership practices in the three countries, discusses their reform experiences, and concludes with implications which may be helpful for promoting and scaling up PPP in primary health care in China.

Objective To study one simple, safe and effective method of periorbital rhytidectomy. Methods With turgescent anesthesia, 1 cm -extent was dissected laterally deep under musculus orbicularis oculi at the approach of eyebrow area. The musculus orbicularis oculi was fixed to the deep temporal fascia and frontal periosteum. The superciliary corrugator muscle and depressor muscle were exposured and cut. Then the eyelid blepharoalasty was performed through the skin incision, meanwhile the lateral pars orbitalis muscle was liberated to form an orbitalis muscle flap under the orbitalis muscle and the fat pad, which was fixed to the os orbitale periost by lifting tight to lateral and upper side. For patients with generous pars buccalis and obvious nose lip ditch, the cheekbone fat cushion was also hanged and fixed. Results 65 middle age female patients were followed up for 3～16 months. The scar was no obvious, glabellar wrinkle and canthal wrinkle disappeared at static state, relaxed upper eyelid and eyebrow prolapse reached to complete correct, nasolabial groove wrinkle obvious lessened. 95 % patients were satisfacted with the appearance. Conjunctival edema was found in 4 cases, and disappeared within 1 months. There were no facial nerve injury and other complications. Conclusions It is a new incisional approach that avoids the facial nerves and lessens fossa orbitalis retrogradation. The operative procedure is simple and safe, and its incision is occult. The wound is small and restores rapidly, but the effect is reliable and lasting. It proves to be an ideal approach for face rejuvenation.

Objective:To analyze a Risk Scale for Emergence Agitation After General Anesthesia in Children (the EA risk scale) into simplified Chinese and evaluate the reliability and validity in children with strabismus correction surgery.Methods:After obtaining the authorization of the original author, the English version of the EA risk scale was translated, translated back and culturally debugged to form the Chinese version of the EA risk scale. Then 279 children with strabismus correction surgery were selected from a tertiary hospital of ophthalmology in Tianjin and were investigated to validate the scale.Results:The correlation coefficients of each item and the total score of the scale were respectively 0.768 (item 1) ,0.717(item 2), 0.676(item 3), 0.634(item 4) (all P < 0.01). Content validity index of the scale was 0.920, and each item was 0.80-1.00. One factors including 4 items were identified using exploratory factor analysis, accounting for 62.052% of the total variance. The optimal cut-off value for the EA risk in children was 10, with the AUG was 0.816, specificity of 0.704, and sensitivity of 0.839. The Cronbach α coefficient for the total scale was 0.819, and the intraclass correlation coefficient value between the scorers was 0.835. Conclusion:The Chinese version of the EA risk scale has good reliability and validity. The items are concise, clear, and easy to understand. It is suitable for clinical departments as a preliminary screening tool to identify emergence agitation after general anesthesia on children with strabismus correction surgery and to assess the risk of its occurrence.

Objective To detect the expression of heat shock protein 47(HSP47) in renal proximal epithelial cell lines (HK-2) and to investigate the role of HSP47 in the progress of transforming growth factor β1 (TGF-β1) induced epithelial-mesenchymal transdifferentiation (EMT) in HK-2 cells.Methods HK-2 cells were exposed to TGF-β1 (0,2.5,5,10 μg/L) for different time (0,12,24,48 h).The expression of HSP47 was examined by Western blotting.Then HK-2 cells were exposed to 10 μg/L TGF-β1,the expressions of vimentin,zona occludens-1 (ZO-1) were examined by Western blotting and real-time PCR.Furthermore,the expressions of p-Smad3 and Smad3 were examined by Western blotting.HK-2 cells were transfected with HSP47 siRNA and siRNA negative control before exposing to TGF-β1.Then the expressions of vimentin,ZO-1 were detected by Western blotting and real-time PCR,meanwhile Western blotting for HSP47,p-Smad3 and Smad3.Results Stimulating HK-2 with TGF-β1 resulted in a significant increased expression of HSP47 in time-and concentration-dependent manner (P ＜ 0.05).Meanwhile,TGF-β1 up-regulated the protein and mRNA expression of vimentin (P ＜ 0.05),and down-regulated the protein and mRNA expression of ZO-1 (P ＜ 0.05),all in time-dependent manner.Stimulating HK-2 with TGF-β1 resulted in phosphorylation of Smad3,which was peaked at 30 min,slightly decreased at 1 h,and then increased again between 24 and 48 h (P ＜ 0.05).Compared to the TGF-β1 group,inhibition of HSP4.7 expression in HK-2up-regulated the protein and mRNA expression of ZO-1,down-regulated the protein and mRNA expression of vimentin (P ＜ 0.05) and down-regulated the ratio of p-Smad3/Smad3.HSP47 siRNA negative control had no significant effect on the expressions of ZO-1,vimentin and p-Smad3/Smad3 (P ＞ 0.05).Conclusion HSP47 can promote the EMT of renal tubular epithelial cell which is possibly via the TGF-β1-Smad3 pathway.

Objective To assess the patient enablement level in a general hospital and its related factors,to investigate the relationship of patient enablement with patient's overall satisfaction and doctor's empathy levels.Methods Patients attending the Family Medicine Clinic of HKU-Shenzhen Hospital in September 2014 and met the inclusion criteria were asked to complete a questionnaire survey which included general characteristics,overall satisfaction;the Patient Enablement Instrument (PEI) and the Consultation and Relational Empathy Measure Scale (CARE) after the consultation.Results Total 2 326 questionnaires were issued and 1 818 were retrieved,of which 1 478 were qualified questionnaires.The qualified rate of PEI was 81.3％ and the qualified rate of patient overall satisfaction was 96.28％.The positive rate of patient enablement was 97.70％ (1 444/1 478),and the mean score of PEI was 8.21 ±3.33.Multivariate linear regression analysis showed that the PEI scores were not influenced by gender and education level of the patients,gender of the consulting doctors and initial/follow up consultation.The PEI scores were influenced by the age of the patients,the types of clinic (general practice/chronic practice clinic) and the reasons for consulting (P ＜ 0.05).There were correlations between PEI score and overall satisfaction of patients (r =0.383,P ＜ 0.001),patient's recommendation of the clinic (r =0.595,P ＜ 0.001) and CARE scores (r =0.546,P ＜ 0.001).Conclusion The results show that the PEI scores of patients visiting family medicine clinic of this hospital are higher than those reported in other studies.The PEI score may be influenced by the age of the patients,the types of clinic and the reasons for consulting.Positive correlations between patient enablement and the overall satisfaction,patient's recommendation and doctor empathy were observed.

Objective To evaluate the effect of a new type of fixation tape for tracheal catheter in intensive care patients.Methods A purposive sampling study was conducted. Ninety patients experienced oral tracheal intubation for mechanical ventilation, and admitted to respiratory intensive care unit (ICU) of the Second Affiliated Hospital of Nantong University from November 2015 to February 2017 were enrolled. All the patients were randomly (random number) divided into the control group and the observation group with 45 patients in each group. The patients in control group was treated with the traditional medical adhesive tape and fixation belt to fix endotracheal tube, while the patients in observation group was treated with a new type of tracheal catheter fixation tape. The fixation effect, skin complication rate, patient's comfort level, nursing workload and satisfaction were evaluated in both groups.Results There were 6 patients with mild displacement, 2 patients with moderate displacement and 1 patient with severe displacement in the control group, while there was no catheter displacement or detachment occurred in the observation group, and the difference between the two groups was statistically significant (χ2 = 2.944,P = 0.003). In the control group, there were 39 patients with facial skin redness,6 patients with facial skin damage, 36 patients with neck skin redness, and 2 patients with neck skin damage. In the observation group, there were no facial skin complications and only 2 patients with neck skin redness, and the skin complication rate was significantly higher than that of the control group (facial skin:Z = 9.173,P = 0.000; neck skin:Z = 7.549,P = 0.000). Compared with the control group, the patients' comfort levels were significantly elevated in the observation group (the intolerance patients: 9 vs. 24, the extreme discomfort patients: 4 vs. 8,Z = 3.695,P = 0.000). The total changing times of the fixation belt and operating time for each change in the observation group were significantly decreased as compared with those of control group [changing times of the fixation belt (times): 1.89±0.77 vs. 3.86±1.18, operating time for each change (minutes): 10.31±1.47 vs. 15.78±1.89, bothP < 0.01]. Nursing satisfaction in the observation group was significantly higher than that of the control group (100% vs. 33.3%,P < 0.01).Conclusions The new fixation tape for tracheal catheter could significantly reduce the catheter displacement and detachment rate, and decreasethe incidence of facial skin injury. It is easy to learn and worth to generalize clinically.

Objective To evaluate the outcomes of thumb reconstruction with dorsal thumb rotated single pedicel reverse island flap.Methods 49 thumb-tip defects cases with dorsal thumb rotated single pedicel reverse island flap were analyzed retrospectively.37 dorsal thumb reverse island flap were performed,and 12 ulnar-dorsal reverse island flaps were performed.Results The operation time was 40-60 minutes.The mean time was 45 minutes.All 49 cases survived completely.The color of the flaps was purple,and blisters in the surface of the flaps after 1-2 days in 2 cases.After took out stitches partly,the blisters were dried and crusted,the color of the flaps with better blood circulation was normal.The follow-up period was 3-24 months,all thumbs had satisfactory appearances and functions.The two-point discrimination was 6-9mm in flaps inosculated with nerve,that was 8-10 mm in flaps inosculated without nerve.The color,texture and elasticity of flaps were excellent,and the donor sites had not been defected.Conclusion Dorsal thumb rotated single pedicel reverse island flap is a reliable option to restore function as well as appearance,long vascular pedicle with skin strap,wide rotation angle,high rate of survival.It avoided damages to the well-known arteries and nerves.It is a relatively facile procedure that can be applied toward resurfacing thumb tip defects.
