Objective To investigate the clinical efficacy of superficial needling therapy for nape myofascitis. Method Seventy patients were randomly allocated to superficial needling and Western medicine groups, 35 cases each. The superficial needling group received superficial needling therapy once every other day, three times a week, two weeks as a course. The Western medicine group took celecoxib (Celebrex) 200 mg twice daily, two weeks as a course. The Pain Visual Analogue Scale (VAS) score, the tenderness score and the Neck Disability Index (NDI) score were recorded in the two groups of patients before and after treatment. Result The VAS score, the tenderness score and the NDI score decreased in the two groups of patients after treatment compared with before (P<0.05, P<0.01) and decreased more in the superficial needling group than in the Western medicine group (P<0.05). The cure and marked efficacy rate and the total efficacy rate were 57.1%and 94.3%, respectively, in the superficial needling group, which were higher than 31.4%and 77.1%in the Western medicine group (P<0.05). Conclusion Superficial needling therapy can better relieve the symptoms and is more effective than oral celecoxib in treating nape myofascitis.

Objective: To observe the therapeutic efficacy of Fu's subcutaneous needling (FSN) in treating scapulohumeral periarthritis (SP). Methods: Eighty patients with SP were randomly divided into an observation group and a control group, 40 cases in each group. Patients in the observation group received FSN treatment while those in the control group received conventional acupuncture treatment. Visual analogue scale (VAS) and range of motion (ROM) were observed before and after the treatment, and the therapeutic efficacy was also evaluated. Results: After the treatment, the VAS scores decreased significantly in the two groups, and the VAS score in the observation group was significantly lower than that in the control group (P<0.01). After the treatment, the ROM increased significantly in both groups (both P<0.01), and the ROM in the observation group was significantly higher than that in the control group (P<0.01). The recovery rate and the total effective rate in the observation group were respectively 40.0% and 95.0%, significantly higher than 12.5% and 77.5% in the control group (P<0.01, P<0.05). Conclusion: FSN can effectively relieve pain and improve the joint motion in treating SP, thus offering a novel option to the treatment of this kind of musculoskeletal disorder.

Objective:To investigate the effect of O-6-methylguananine-DNA methyltransferase (MGMT) gene promoter methylation status on the treatment and prognosis of elderly patients newly-diagnosed with glioblastoma (GBM).Methods:Clinical data of 65 newly-diagnosed GBM patients admitted to Tianjin Huanhu Hospital from January 2012 to December 2018 were retrospectively analyzed. All patients received intensity-modulated radiotherapy after surgery and 49 patients received temozolomide (TMZ) monotherapy. All patients were divided into the MGMT(+ ) group and MGMT(-) group according to the methylation status of MGMT promoter. Kaplan- Meier method and log-rank test were used for univariate survival analysis, and Cox regression model was used for multivariate prognostic analysis. Results:The median overall survival (OS) for all patients was 18.0 months. The median OS was 27.0 months and 15.3 months in the MGMT(+ ) group and MGMT(-) group, respectively. Univariate analysis revealed that tumor number, MGMT promoter methylation, postoperative concurrent chemoradiotherapy were significantly related to clinical prognosis ( P=0.029, P=0.001 and P<0.001). In multivariate analysis, tumor number and postoperative concurrent chemoradiotherapy were identified as significant prognostic factors for OS ( P=0.037, P=0.004). In the MGMT(+ ) group, the median OS was 27.0 months for patients receiving concurrent chemoradiotherapy and 12.0 months for radiotherapy alone ( P=0.040). In the MGMT(-) group, the median OS was 17.0 months for concurrent chemoradiotherapy patients and 10.0 months for radiotherapy alone ( P=0.122). Conclusions:MGMT promoter methylation status is significantly associated with longer OS in elderly GBM patients. Conventional fractional radiotherapy combined with concurrent and sequential TMZ chemotherapy probably yields better survival benefits.

Objective T o investigate the relationship betw een the expression of secreted frizzled-related protein 5 (SFR P5) m RNA and the tim e interval after skeletal m uscle injury in rats by real-tim e PC R . Methods A total of ninety SD rats w ere random ly divided into the contusion groups at different tim es including 4 h, 8 h, 12 h, 16 h, 20 h, 24 h, 28 h, 32 h, 36 h, 40 h, 44 h, 48 h after contusion, incision groups at different tim es including 4h and 8h after incision and the control group. T he sam ples w ere taken from the contused zone at different tim e points. T he total RNA w as isolated from the sam ples and re-versely transcribed to analyze the expression levels of SFRP5 m RNA . Results C om pared to the control group, the expression of SFRP5 m RNA in contusion groups w ere dow n-regulated w ithin 48 h after con-tusion and reached the low est level at 20 h, and the expression of SFRP5 m RNA gradually increased from 20 h to 48 h after contusion. T he expression of SFRP5 m RNA in the incised groups w ere signifi-cantly low er than that of the contusion groups at 4 h after injury. A t the tim e of 8 h, the expression levels betw een the contusion and incision groups show ed no statistically significant difference. Conclusion It is suggested that SFRP5 m RNA analysis m ay show regular expression and can be a m arker for estim ation of skeletal m uscle injury age.

Objective To investigate the role of transoralsonography guiding fine?needle aspiration biopsy in the diagnosis of retropharyngeal or parapharyngeal masses identified on the CT, MRI or PET?CT images of treated patients with malignant carcinoma. Methods From 2002 to 2013,this study recruited fifty?five patients with a history of cancer, of which 50 were treated with radiation treatment, including 46 nasopharyngeal carcinoma, 3 esophagus squamous cell carcinoma and1 lung apex carcinoma. There were 4 patients with a history of 1 thyroid papillary carcinoma, 1 buccal mucosa squamous cell carcinoma,1 glottis squamous cell carcinoma and 1 sigmoid colon adenocarcinoma treated with surgery. The rest one patient with nasal olfactory neuroblastoma was treated by postoperative radiation. The enlarged retropharyngeal lymph nodes in 44 cases and parapharyngeal masses in 10 cases were identified on CT or MRI imges. The enlarged retropharyngeal lymph node in the rest case was identified on PET?CT. With transoral ultrasound examination, all lesions were with hypo?intensity echo. Cystic areas were noted on occasion. Biopsy was performed in all cases. Results After cytology examination, carcinoma cells were detected in 37 retropharyngeal lymph nodes, with a detection rate of 82% (37/ 45). In the 10 parapharyngeal masses, carcinoma cells were detected in 3 lesions, with a detection rate of 30%. Conclusions Transor alsonography guiding fine?needle aspiration biopsy can be useful in the cytopathology diagnosis of retropharyngeal or parapharyngeal masses identified on the CT, MRI or PET?CT images of treated patients with malignant carcinoma,which facilitates, early diagnosis and treatment for patients.

Objective:To investigate the protective effect of lactoferrin(Lf) on lung injury in mice exposed to irradiation.Methods:C57BL/6 J mice were randomly divided into control group, 15 Gy irradiation group (IR group) and lactoferrin combined 15 Gy irradiation group (Lf+ IR group), with 5 mice in each group. The mice in the Lf+ 15 Gy group drank lactoferrin solution (10 mg/ml) from 3 days before irradiation and contained the whole experiments. Then, single chest 15 Gyirradiation was performed both in the IR and Lf+ IR groups. The body weight and other characteristics were monitored during the experiment. The mice were killed at day 14 after irradiation. The lung histopathology was observed by HE staining. Serum inflammatory cytokine such as HMGB1, TNF-α, IL-1β and IL-6 was determined by ELISA method . The expression of inflammatory related protein in lung tissue including HMGB1, TLR4, MyD88 and NF-κB were performed by immune histochemistry and Western blot method.Results:Compared with the control group, lung weight was significantly increased ( t=3.20, P<0.05), pulmonary hyperemia and inflammatory cell infiltration was observed in the IR group. Exposure also significantly increased serum level of TNF-α[(291.80±5.49) vs.(332.25±22.18)pg/ml]( t=3.07, P<0.05), up-regulated the expression of inflammatory related protein in lung tissue ( t=4.04, 4.78, 3.77, 6.14, P<0.05). Lactoferrin intervention (Lf+ IR group) significantly decreased lung weight ( t=2.18, P<0.05), alleviated histopathologic changes, decrease serum levels of HMGB1, TNF-α and IL-1β ( t=4.67, 2.97, 3.49, P<0.05). On the other hand, lactoferrin intervention decreased the positive cell number of HMGB1 and NF-κB, and down-regulated the protein expression of HMGB1, TLR4, MyD88 and NF-κB in lung tissues, with significant difference with the IR group ( t=8.06, 9.80, 3.07, 5.56, P<0.05). Conclusions:Lactoferrin plays the protective effect of radiation-induced lung injury through the downregulation of inflammatory response, such as HMGB1/TLR4/MyD88/NF-κB signaling pathway.
