Objective To evaluate results of double eyelid operations with different incisions.Methods 100 patientswere selected randomly from out-patients that accepted double eyelid operation.Half of them were objected to double eyelid operation through a palpebral marginal incision.Incision was designed along the palpebral margin,close to boots of eyelashes.Most of the subcutaneous tissues was cut and removed,and then dermis and tarsal plate were fixed with 5 stitches of suture.About 1-3 mm wide of skin along superior margin was removed reasonably.In another 50 cases.double eyelid operation was performed with conventional incision.Incision was designed 6-8 mm far from the palpebral margin.Most of the subcutaneous tissues was removed.and then dermis and tarsal plate were fixed with 5 stitches of suture.Results Postoperative results were evaluated 5 days and 1 month after operation respectively.Postoperative double eyelid shapes were all satisfled in two groups.Swollen eyedids and scar were more inconspicuous in the cases with the palpebral-marginal incision without impairment on eyelashes.Conclusion Compared with double eyelid operation with conventional incision,blepharoplasty with palpebral margin incision has the same results but with lighter impairment,milder hydropsia and more inconspicuous scar.The key point of this procedure is the fixation of dermis and tarsal plate,keeping a good radian of double eyelid line.

BACKGROUND: As for the treatment of chylous fistula concurrent in oral-maxillofacial tumor resection simultaneously undergoing neck lymph node dissection, many different approaches have been put forward. A simple surgical ligation, strong negative pressure drainage, filling the muscle tissue alone or a combination of the above methods are all unsatisfactory regarding the prognosis and curative effect.OBJECTIVE: To evaluate the validity of medical biological adhesive cohering peripheral autologous muscle tissues to block thoracic duct fistula in order to prevent chylous fistula following neck lymph node dissection.METHODS: All of the 12 patients were detected and diagnosed as chylous fistula in neck lymph node dissection surgery, the wounds were immediately sutured and treated with medical biological adhesive cohering peripheral autologous muscle tissues to block thoracic duct fistula. RESULTS AND CONCLUTION: Of all the 12 patients, 10 recovered without chylous fistula or severe complications, and reoperations were adopted to cure the failed 2 cases. All patients were visited 3 months postoperatively, no recurrence of chylous fistula, local stimulus response or allergy was found. It is suggested medical adhesive to block thoracic duct fistula may be an effective and safe way for prevent chylous fistula following neck lymph node dissection.

Mechanical ventilation (MV) with large tidal volumes can increase lung alveolar permeability and initiate inflammatory responses,resulting in ventilator-induced lung injury (VILI).The mechanisms of the injurious effects of MV and the genetic susceptibility remain unclear.VILI-related genes such as cysteine-rich angiogenic inducer 61 (Cyr61)have been demonstrated to play a detrimental role in the aggressive ventilation strategies.In the present study,we investigated the involvement of Cyr61 in the VIM and the underlying mechanism.A549 cells were exposed to cyclic stretch of varying durations and then the mRNA and protein levels of Cyr61 were measured by real-time PCR and Western blotting,respectively.Additionally,after exposure ofA549 cells to cyclic stretch for 5 min to 1 h,the expression levels of nuclear factor kappaB (NF-κB) and IL-8 were detected by ELISA and Western blotting.Thereafter,Cyr61 expression was depressed in A549 cells with the siRNA pGenesill.1-Cyr61-3 before the cyclic stretch,and IL-8 secretion and the activation of NF-κB pathways were probed by ELISA and Western blotting,respectively.Moreover,a NF-κB inhibitor (PDTC) and an activator (TNF) were used before mechanical stretch.Realtime PCR and ELISA were performed to detect the mRNA and protein of IL-8,respectively.The results showed that the mechanical cyclic stretch led to increased Cyr61 expression at mRNA and protein levels in A549 cells.Additionally,cyclic stretch also mobilized NF-κB from the cytoplasm to the nucleus and increased IL-8 secretion in A549 cells.The inhibition of Cyr61 blocked the NF-κB activation and IL-8 secretion in response to cyclic stretch.Inhibition of NF-κB attenuated the mRNA and protein expression of IL-8 in A549 cells transfected with Cyr61 siRNA.It was suggested that Cyr61/NF-κB signaling pathway mediates the upregulation of IL-8 in response to cyclic stretch in A594 cells.These findings support the hypothesis that Cyr61 plays a critical role in acute lung inflammation triggered by mechanical strain.

Objective To investigate the association of radial arterial calcification damage with bone mineral density (BMD) and bone metabolism biomarkers in uremia patients.Methods Sixty-seven incident hemodialysis patients were recruited into uremic group.Serum creatinine,calcium,phosphorus,lumbar spine and femoral neck BMD were measured.Parathyroid hormone (iPTH),25OHD,1,25(OH)2D,fibroblast growth factor (FGF) 23,bone specific alkaline phosphates (BAP) and osteocalcin (BGP),type Ⅰ collagen pyridine crosslinked C-telopcptidc (ICTP) were detected.Radial artery calcification was analyzed by von Kossa staining and transmission electron microscopy.Arterial type Ⅰ collagen (Col Ⅰ) expression was examined.Twenty-three healthy cases received serum and BMD examination only as control.Results Uremic patients presented higher serum phosphate,iPTH,FGF23,lower serum calcium,25OHD,1,25 (OH)2D (all P ＜ 0.05),and lower lumbar spine and femoral neck BMD (all P ＜ 0.01) compared to controls.Significant calcium deposit was observed in radial arteries in 24 uremic cases (35.8％),including 10 cases of diabetes.Immunohistochemistric assay confirmed that Col Ⅰ expression increased around calcification site and electron microscope revealed that more calcium and phosphorus plaque attached among collagen fibers.No correlation was showed between iPTH and radial artery calcification (r =-0.08,P =0.306),but after stratified by iPTH levels,correlation of iPTH and calcification was found in low iPTH (＜ 150 ng/L) group and high iPTH group (＞ 300 ng/L) (r =-0.41,0.31,P=0.044,0.023).Diabetes,lumbar spine and femoral neck BMD,ICTP,FGF23 were correlated with arterial calcification (r =0.62,-0.25,-0.43,0.34,0.86,P =0.000,0.001,0.012,0.018,0.000).Multiple regression analysis showed femoral neck BMD,ICTP,FGF23 levels were independently associated with radial arterial calcification (β =-0.221,0.181,0.260,P =0.021,0.024,0.036).Conclusion In uremic patients,reduced BMD,abnormal bone turnover rate,especially accelerated bone reabsorption,and increased serum FGF23 level are independently associated with radial artery calcification.

OBJECTIVETo establish a method for studying efficacious materials of traditional Chinese medicines from an overall perspective.

METHODCarthamus tinctorius was taken the example. Its major components were depleted by preparing liquid chromatography. Afterwards, the samples with major components depleted were evaluated for their antioxidant effect, so as to compare and analyze the major efficacious materials of C. tinctorius with antioxidant activity and the contributions.

RESULTSeven major components were depleted from C. tinctorius samples, and six of them were identified with MS data and control comparison. After all of the samples including depleted materials are compared and evaluated for their antioxidant effect, the findings showed that hydroxysafflor yellow A, anhydrosafflor yellow B and 6-hydroxykaempferol-3, 6-di-O-glucoside-7-O-glucuronide were the major efficacious materials.

CONCLUSIONThis study explored a novel and effective method for studying efficacious materials of traditional Chinese medicines. Through this method, we could explain the direct and indirect contributions of different components to the efficacy of traditional Chinese medicines, and make the efficacious material expression of traditional Chinese medicines clearer.

Abstract: Objective　To analyze the epidemic characteristics of hand, foot and mouth disease (HFMD) in Nanping City, Fujian province and to provide the basis for formulating effective prevention and control measures as well as evaluating the efficacy of prevention and treatment. Methods　Descriptive epidemiological method was used to analyze the incidence data of HFMD in Nanping City from 2012 to 2021. Results　A total of 49 231 cases of HFMD were reported in Nanping City from 2012 to 2021. The incidence fluctuated greatly over the 10-year period, ranging from 76.10/100 000 to 308.93/100 000, with an average incidence of 184.99/100 000 per year. The overall incidence and the number of cases showed a fluctuating downward trend over time, but the incidence was high in the next year, and there were statistically significant differences in the incidence rates between different years(χ2=8 169.176, P<0.001). There were significant regional differences in the incidence, the top three average annual incidence rates were: Guanze County (370.76/100 000), Zhenghe County (295.31/100 000) and Wuyishan City (250.31/100 000). There were two peaks of HFMD incidence each year, with the first occurring in May and June and the second occurring in September and October. The incidence rate was higher among males (215.86/100 000) than females (152.93/100 000), and males were more susceptible than females (RR=1.412, 95%CI=1.387-1.438). The cases were mainly aged 0-4 years, accounting for 86.25% (42 461/49 231) of all cases, and the incidence rate gradually decreased with increasing age (χ2trend=570,105.801, P<0.001). The majority of cases (85.22%, 41 953/49 231) occurred in children living in scattered areas, followed by children in kindergartens (12.39%, 6 101/49 231). The etiological results showed a total of 3 476 laboratory-confirmed cases, and the proportion of three (classes) of enterovirus positivity varied each year, with different pathogen compositions showing statistical significance (χ2=584.613, P<0.001). In addition to the years 2015-2017, during which Cox A16 and EV71 were the dominant strains, other years were dominated by other enteroviruses, with EV71 being the main type in severe and fatal cases of HFMD in Nanping City. Conclusion　Nanping City should strengthen health education for children living in the diaspora and in day-care centers, enhance surveillance of epidemics and pathogenology, improve vaccination rates against EV71, focus on the detection and typing of other enteroviruses, and implement effective prevention and control measures for HFMD.

OBJECTIVETo analyze and evaluate the acceptability of mifepristone compatible with misoprostone versus conventional surgical abortion among women under unwanted early pregnancy, so as to help the unexpected pregnant women to choose the satisfactory abortion, and to provide the evidence for clinicians to make a proper clinical decision.

METHODSSix medical databases were searched, including MEDLINE, EMBASE, Cochrane library, CBMdisc, CNKI and VIP, together with twelve journals hand-searched, and references of included studies additionally searched. Two qualified reviewers reviewed the original articles, evaluating qualities of articles, and extracting data independently. After heterogeneity test, the data was pooled using Revman software if capable, or descriptive analysis was applied.

RESULTSIn total, nine original clinical controlled trials were included, containing 3565 cases. Before abortion, more unwanted pregnant women chose the medical abortion because they believed medical abortion was less painful than surgical abortion (OR = 466.51, 95% CI: 91.37 - 2381.88), but medical abortion was less time-consuming than surgical abortion (OR = 0.02, 95% CI: 0.01 - 0.06). After abortion, satisfaction with medical abortion was similar to that with surgical abortion, with insignificant difference (P = 0.89). However, second choice and recommendation rates of medical abortion were much higher than those of surgical abortion with OR and 95% CI as 2.72, 2.13 - 3.47 and 4.19, 2.16 - 11.16, respectively.

CONCLUSIONSMedical abortion was less painful than surgical abortion and the rate of second choice and recommendation to others were all also higher than those of surgical abortion. However, the process of medical abortion was not as quick as surgical abortion but the satifacation of both methods seemed similar. Therefore, the two artificial abortion methods were not recommended to replace each other at the present time.
