Objective To summarize the clinical effect of individualized cranioplasty with different materials. Method The clinical data of 75 patients with skull defect were analyzed retrospectively. Ultrathin cranial CT and three-dimension reconstruction were done to delineate the shape and contour of cranial defect. The templet for repair was fabricated with methyl silicone rubber, bone cement or titanium mest according to the condition of the bone defect with laser rapid prototyping technique. With patient's consent, the individualized templet was implanted to repair the cranial defect. Results Methyl silicone rubber or bone cement were used for 40 of 75 patients to fill the defects, and in the other 35 patients titanium mesh was used to cover the defects with overlapping edges. The patches matched cranial defect perfectly without the necessity of revision. The average operation time was 45 minutes. Perfect or excellent cosmetic results was obtained in 63 of the 75 patients (84%). Postoperative complications were as follows: 5 patients complained of headache, which disappeared in there months. Collection of fluid under the scalp was found in 12 patients, among them the fluid was Absorbed 10 days after operation in 8 cases without any treatment, while in 3 patients it disappeared after suction for 1-4 times. In the remaining one patient, the bone cement templet was removed due to infection, and a titanium mesh was implanted one year later. Loosening and displacement of the templet occurred in 2 patients, and silk sufures were used for fixation in both patients. In these two patients, the templet became stable 3 months later, and in the other titanium was used for repair one year later. The incidence of complications was signifieantly different between inlay and onlay methods of repair (P

Objective To investigate the effects of magnitude of surgical trauma and duration of operation on aggregation and adhesion of platelets during laparoscopy and conventional laparotomy cholecystectomy. Methods Thirty ASA Ⅰ-Ⅱpatients(male 11, female 19) undergoing elective cholecystectomy were studied . The mean age was(45 .2 ? 8.3) years and mean body weight(63.3 ?12. 6)kg. The patients were divided into two groups: laparoscopy group(group LC) and laparotomy group(group OC). Patients who took any drugs which may affect blood coagulation were excluded. Blood routine examination, coagulation and bleeding time were normal in all patients. In both groups anesthesia was induced with fentanyl 0. 1-0.2mg, propofol 2mg/kg and vecuronium 0.1mg/kg and maintained with isoflurane inhalation. Venous blood samples were taken after induction of anesthesia and 1h and 2h after operation was started. 10ml of blood was withdrawn from median cubital vein for the measurement of platelet adhesion(PAdT) and plasma level of platelet membrane glycoprotein(GPⅠ b/Ⅰ x) and von Willebrand factor(vWF) . Venepuncture was made at first attempt without using tourniquet. Plastic syringes were used and first 2ml of blood withdrawn was discarded . Glass ball method was used for measurement of PAdT which was calculated according to the following equation: Rate of platelet adhesion(% ) = /(No. of platelet before adhesion-No. of platelet after adhesion) No. of platelet before adhesionGP Ⅰ b/Ⅰ x and vWF levels were measured using ELISA method. Results There was no significant difference in PAdT and GP Ⅰ b/Ⅰ x and vWF levels after induction of anesthesia between two group. PadT level was significantly lower at 1 and 2h during surgery in group LC than that in group OC. GPⅠh/Ⅰx level was higher at 1h during operation in group OC than that in group LC and was much higher at 2h during surgery. vWF level decreased significantly at 2h during operation in both groups. Conclusions Platelet adhesion rate increases during operation and the severer the trauma the higher the platelet adhesion rate. GPⅠ b/Ⅰ x level is higher in group OC during operation than that in group LC probably due to severity of trauma. vWF is consumed during operation.

Objective To evaluate the clinical application value of multislice spiral CT (MSCT) in diagnosis andclinical treatment of the chronic suppurative otitis media(CSOM). Methods Multislice spiral CT with direct axial plane and saggitalmultiplanar reformation(MPR) were performed in 61 cases including 76 ears.The results from those images were comparedwith that of operations. Results The sagittal MPR images preferably could delineate the anatomical details of the temporal bone and theadjacent relationship,and could display the tympanicand mastoid segment of the facial nerve,sigmoid sinus plate and the glomusjugular better.On the sagittal MPR images,the disruption of the ossicular chain and bony erosion in the tympanic cavity and antrum weredisplayed in 38 ears.The destruction of the facial nerve canal was severe in the type of cholesteatoma compared with the type of granuloma of chronic suppurative otitis media.The congenital abnormities were showed in 8 ears of the sigmoid sinus plate and 2 ears of the glomus jugular.Conclusion CT sagittal MPR images are of significant clinical value in showing the degree and location of destruction of the canal of facial nerve , and the relation between around structures in chronic suppurative otitis media.

Objective To systematically evaluate the risk factors for upper extremity lymphedema after breast cancer treatment and the strength of their associations.Methods PubMed,Ovid,EMbase,and the Cochrane Library were searched to identify clinical trials published up to December 2012.The quality of included studies was assessed by the Newcastle-Ottawa Scale;data analysis was performed by Stata 10.0 and RevMan 5.2;the strength of associations between risk factors and breast cancer-related upper extremity lymphedema was described as odds ratio (OR) and 95％ confidence intervals (CI).Results Twenty-two studies involving 10106 patients were included in the meta-analysis.The risk factors for upper extremity lymphedema after breast cancer treatment mainly included axillary lymph node dissection (OR =2.72,95％ CI=1.06-6.99,P=0.038),hypertension (OR=1.84,95％ CI=1.38-2.44,P=0.000),body mass index (OR =1.68,95％ CI=1.22-2.32,P =0.001),and radiotherapy (OR =1.65,95％ CI =1.20-2.25,P =0.002),while no significant associations were found for such factors as chemotherapy,age,number of positive lymph nodes,and number of dissected lymph nodes.Conclusions The incidence of upper extremity lymphedema is high among patients with breast cancer after treatment,and axillary lymph node dissection,hypertension,body mass index,and radiotherapy are the main risk factors for lymphedema after breast cancer treatment.

Objective To observe the effects of fructose,fibroblast growth supplement(FGS) and ethylamine sulfonic acid on the total number,the survival rate and the survival number of Human Retinal Pigment Epithelial(hRPE) Cell.Methods Microencapsulated hRPE cells were plated and cultured in four kinds of mediums,which contained fructose,fibroblast growth supplement(FGS),ethylamine sulfonic acid or no extra ingredient respectively.The total cell number,survival rate and viable cell number of the microencapsulated hRPE cell on day 0th,1st,3rd,7th were calculated.Results After 7days of culture,the lowest cell survival rate of microencapsulated hRPE cells in the four groups was(75.00±3.00)%,but there were no significantly differences(Ps＞0.05) among the groups.The total number of cells in the fibroblast growth factor group([8.00±0.46]×104) and ethylamine sulfonic acid group([7.20±0.36]×104) were significantly higher than the blank group(([6.10±0.56]×104),Ps＜0.05),while no statistical difference was observed in the comparison between the fructose group([6.00±0.46]×104) and blank control(P＞0.05).Conclusion The FGS and ethylamine sulfonic acid can promote the proliferation of the microencapsulated hRPE cells.

Objective To investigate the pathological features of chronic inflammation in prostatic specimens,and study the correlation of chronic prostatic inflammation with prostate cancer and hyperplasia of prostate in the elderly.Methods The histopathologic features of prostatic specimens which were taken during prostatectomy were retrospectively observed.The inflammatory cells in partial cases were labeled by immunohistochemical markers such as CD3,CD20,CD4,CD8,CD117 and CD138,and by inflammation related factors such as nuclear factor(NF)-κB,(COX-2),tumor necrosis factor-α(TNF-α)and inducible nitric oxide synthase (iNOS).Results The chronic prostatic inflammation of different extent were found in 100 patients with prostate cancer and 76 patients with benign prostatic hyperplasia,among them 71 cases (40.3 ％) had mild chronic prostatic inflammation,80 cases (45.5 ％) had moderate chronic prostatic inflammation,25 cases (14.2 ％) had severe chronic prostatic inflammation.Inflammatory cells mainly were CD3-labeled lymphocytes,accompanied by a small amount of mononuclear cells and mast cells.Chronic prostatic inflammation was not correlated with prostatic carcinoma and its differentiation degree,benign prostatic hyperplasia,focal atrophy and its subtypes,and high grade prostatic intraepithelial neoplasia (all P＞ 0.05).There was correlation between chronic prostatic inflammation and expression of COX-2 (P＜ 0.05).Conclusions The histological chronic inflammation is common in the prostate specimens in elderly men.There are no direct correlations of prostatic inflammation with prostatic carcinomas and benign prostatic hyperplasia.Prostatic inflammation is positively correlated with the expression of COX 2,which may be associated with the activation of COX-2 pathway induced by oxidative stress.

Objective:To compare the quality differences in benzalkonium chloride samples from domestic and abroad to provide references for the quality standard revision for benzalkonium chloride in Chinese pharmacopoeia. Methods: The ratio of alkyl compo-nents was determined according to the method described in USP 38, and the total content of benzalkonium chloride was determined ac-cording to the method recorded in Chinese Pharmacopoeia (2015 edition) and USP 38, respectively. Results:According to the results of composition ratio of alkyl, the fraction defective of domestic samples and imported samples was 100% and 50%, respectively. The content difference between the values calculated by the methods in the two pharmacopoeias showed that the total content of domestic samples changed from 3. 86% to 4. 15%, and that of imported samples changed from 1. 15% to 3. 90%. Conclusion:There are sig-nificant differences in the quality of benzalkonium chloride between domestic samples and imported samples. It is recommended that the ratio of alkyl components should be supplemented in our pharmacopoeia referring to the method in USP 38 and the total content calcula-tion formula for benzalkonium chloride should be revised to improve the quality standard for benzalkonium chloride.

OBJECTIVE: To investigate the possibility of thyroidectomy/lobectomy without drainage after surgery. METHOD: Eighty-eight consecutive cases with thyroid mass have been underwent operations including: lobectomy group(42 cases), thyroid lobectomy with contralateral partial thyroidectomy group (17 cases) and total thyroidectomy group (29 cases) from 2013. 06 to 2014. 06 in Nanjing Tongren Hospital. FIfteen patients with thyroid operation in other hospital were collected from 2014. 01 to 2014. 06, the recovery of postoperative incision were compared. RESULTS: Eighty-four cases were smoothly discharged from hospital except 4 thyroidectomy cases suffered from a small amount of effusion in surgical cavity. Our postoperative wound recovery were more in line with the principle of cosmetology compared with other hospital operation group. CONCLUSION Drainage following thyroidectomy is not essential, if the thyroid surgery is meticulous in each step of the surgery, and can increase the effect of beauty.
