Objective To observe the effect of pulsed radiofrequency (PRF) on refractory infraorbital neuralgia. Methods From January, 2012 to December, 2014, 49 patients who received ineffective conservative therapy including medicine and nerve blockade underwent PRF treatment. Postoperative Numeric Rating Scale (NRS)=0 or 50%diminution of NRS was considered effective. NRS, effective rate, addition-al carbamazepine dosage and side effects were recorded on the first day, the first week, the second week, the first month, the third month, the sixth month, the first year, and the second year after operation. Results The effective rate were 67%, 67%, 65%, 59%and 51%on the first month, the third month, the sixth month, the first year, and the second year after operation, respectively. No serious side effect was observed, except that eight patients felt short-term (within one month) mild numbness. Conclusion PRF technique is safe and effective for refractory infraorbital neuralgia, and may become an alternative therapy.

Objective To observe the effect of radiofrequency thermocoagulation on patients with refractory supraorbital neuralgia Methods From February, 2007 to September, 2014, 36 patients with refractory supraorbital neuralgia following ineffective conservative ther-apy including medicine and nerve blockade underwent radiofrequency thermocoagulation. Numeric Rating Scale (NRS), Patient Satisfaction Scale (PSS), onset time, effective rate, recurrence rate, additional carbamazepine dosage and side effects were recorded before, and one day, one month, three months, six months, one year, two years after treatment. NRS=0 or 50%diminution was considered effectively. Results It worked two days on average (zero to seven) after treatment. The NRS score decreased (P<0.05) and the PSS score increased (P<0.05) com-pared with the data before treatment. The effective rate was 100%within six months. The recurrence rate was 11.1%within two years. Sec-ond radiofrequency thermocoagulation treatment still worked for the recurrent patients. No other side effect was observed, except permanent frontal numbness, short-time palpebral edema and ecchymosis. Conclusion Radiofrequency thermocoagulation is effective on refractory su-praorbital neuralgia, and the side effects are tolerable so it is an alternative choice for patients experiencing invalid conservative therapy.

Objective To explore the methods for endoscopy nasal microsurgery and multiple techniques in treatment of nasopharyngeal angiofibromas. Methods CT, MRI and digial substraction angiography (DSA) and endoscopic examination had been used. ALL 12 patients accepted preoperative feeding artery embolum, hypotention anesthesia and injected adrenaline-lidocaine. Microelectrotomy-electrocoagulation had been used to remove tumor. Results All patients were treated by endoscopic nasal surgery. No complications had occurred. No recurrence were found in follow-up period. Conclusion The important factors to reduce amount of introperative bleeding are to select proper operative patients and use multiple techniques. Endoscopy nasal surgery has dominance in reducing complications, wound, tumor recurrence, operative time and nasal function.

Objective To observe the effect of human umbilical cord-derived mesenchymal stem cells (hMSCs) on type 2 diabetic rats, and to explore the possible mechanism. Methods Type 2 diabetic rats were induced by high-fat diet combined with a low dosage of streptozotocin ( STZ, 25 mg/ kg). After 3 × 106 hMSCs suspended in 1 ml PBS or 1ml 10-fold concentrated hMSC supernatant were intravenously infused into the rats via the tail vein, the blood glucose levels were measured every day. One week later, intraperitoneal glucose tolerance test and insulin tolerance test were performed to evaluate the effects of hMSCs on diabetic rats. Pancreatic tissues were collected for insulin/ glucagon immunofluorescence staining. Results After hMSCs infusion, blood glucose level and homeostasis model of assessment for insulin resistance index were significantly decreased in type 2 diabetic rats(both P<0. 01). The glucose tolerance and insulin tolerance were greatly alleviated by hMSCs(all P<0. 01). Intravenously infused 1ml 10-fold concentrated hMSC supernatant showed a similar result to hMSCs. Conclusion In type 2 diabetic rats, hMSCs are able to effectively lower the blood glucose level, improve insulin sensitivity, and increase the number of β cells, which seems to be mediated by their secreted molecules.

Objective To investigate the differences of measurement of gross target volume (GTV)between endoscopic ultrasonography ( EUS )-based ( GTVEUS ) and computed tomography ( CT ) -based (GTVCT) method for thoracic esophageal squamous cell carcinoma. Methods EUS was performed on 36consecutive patients with thoracic squamous cell carcinoma, and the superior and inferior boarders of the tumor defined by EUS were marked with hemoclips. The CT planning scan was then performed with the patient in supine position, and the GTVCT and GTVEUS were contoured respectively. The lengths ( LCT and LEUS) and spatial locations of longitudinal GTVCT and GTVEUS were compared. Results The mean LCT and LEUS were (7. 79 ± 3. 15 ) cm and (7. 42 ± 2. 72) cm, respectively ( t = 0. 82, P > 0. 05 ), with a correlation coefficient of 0. 61 (P <0. 001 ). Locations of longitudinal GTVCT and GTVEUS were compared in 34cases, with 2 excluded for invisualization on CT. The mean conformal index (CI) was (0. 79 ± 0. 18 ), and spatial variations were found in 71% patients, with 8 patients at proximal end and 21 others at distal end.There was no clip placement associated complication. Conclusion Endoscopic hemoclips placement is safe and reliable. EUS can provide additional information to CT in defining longitudinal GTV in thoracic esophageal squamous cell carcinoma, especially in superficial and submucosal carcinomas.

Objective To investigate the ability of linked color imaging(LCI)for diagnosing Helicobacter Pylori(Hp)infection compared with conventional white light imaging(WLI). Methods We prospectively collected subjects who underwent gastroscopy. Images under both WLI and LCI were recorded and analyzed. Software was used to measure pixel brightness for red(R),green(G),blue(B)of endoscopic images from suspected lesion sites. Biopsies were taken from these sites and Warthin-Starry silver staining was used to detect if Hp was present. R/(G+B)value was used to construct receiver operating characteristic curve(ROC)to predict Hp infec-tion and the area under curve(AUC),cut-off point,sensitivity,as well as specificity were calculated with the patho-logy as the gold standard. Results Forty-seven subjects(23 men,24 women;23 Uygur subjects,24 Han subjects) were included in a mean age of 49 years old. Ninety-one biopsies were obtained. Forty-four biopsies (48.4%)were Hp positive according to the pathology. The AUC of LCI was 0.616,with the cut-off point at 0.967 and sensitivity at 0.955 and specificity at 0.298. The AUC of WLI was 0.529,with cut-off point at 2.638 and sensi-tivity at 0.455 and specificity at 0.766. The AUC of Han and Uygur subjects were 0.650 and 0.549 by LCI. The AUC of atrophy gastritis subjects and non-atrophy gastritis subjects were 0.628 and 0.603. Conclusion LCI was superior to WLI in predicting Hp infection. LCI may act as an objective and quantified endoscopic diagnostic meth-od in Hp infection.

Objective To investigate the effects of sodium butyrate on the activity of RAW264.7 cells and the osteoclast differentiation.Methods The RAW264.7 cells were treated by sodium butyrate at concentrations of 0,0.25,0.50,1.00,2.00,3.00,4.00 and 5.00 mmol/L,with 3 double pores for each concentration.The cytotoxicity of sodium butyrate on RAW264.7 cells was detected by a CCK-8 kit.The effects of sodium butyrate (0,0.25,0.50 and 1.00 mmol/L) on apoptosis of RAW264.7 cells were detected by Hoechst33342 staining.RAW264.7 cells were induced into osteoclasts by osteoclast differentiation factors.The experiment was carried out in 2 groups (n =3).After induced maturation,the experimental group was treated with 1.00 mmol/L sodium butyrate and the control medium was added only with the same volume of solvent.The number of osteoclasts and the area of bone resorption were observed and compared.The differentiation of RAW264.7 cells was detected by tartrate-resistant acid phosphatase (TRAP) staining.Western blotting was used to detect the effects of sodium butyrate (0,0.25,0.50 and 1.00 mmol/L) on NF-κB-related signaling pathway in RAW264.7 cells.Results Compared with the group of 0 mmol/L sodium butyrate,the activity of cells treated with 1.00,2.00,3.00,4.00 and 5.00 mmol/L sodium butyrate for 24 h was significantly decreased (P < 0.05).Treatment with 1.00 mmol/L sodium butyrate for 24 h induced apoptosis.The number of osteoclasts in the control group and the experimental group were 9.33 ± 2.08 and 4.67 ± 1.16,respectively,showing a significant difference between the 2 groups (t =3.395,P =0.027).The percentages of bone resorption area in the control group and the experimental group were 52.43% ± 5.38% and 14.28% ± 2.72%,respectively,also showing a significant difference between the 2 groups (t =10.970,P < 0.001).Western blot results showed that,compared with other concentrations of sodium butyrate,treatment with 1 mmol/L sodium butyrate on RAW264.7 cells for 24 h led to an increase in the expression levels of cytoplasmic p65,B lymphoma-2 associated X protein and cleaved-caspase 3 and the acetylation of Histone H3 but a decrease in the phosphorylation level of α/β subunit of NF-κB kinase.Conclusions With the increased concentration of sodium butyratecan,the activity of NF-κB may be suppressed and the number of apoptotic cells may increase.1.00 mmol/L sodium butyrate can reduce osteoclast formation and bone resorption area.
