Objective To investigate the effect of music electroacupuncture on perifocal ferric ions and neuronal apoptosis and the brain water content in rats with acute cerebral hemorrhage and explore the mechanism of its action on acute cerebral hemorrhage.Methods One hundred and twenty-eight healthy adult male Wister rats were randomized to normal, model, electroacupuncture and music electroacupuncture groups. In each group, four time points of 6 hrs, 24 hrs, 3 days and 7 days were set up, eight rats each time point. A rat model of acute cerebral hemorrhage was made using collagenase. In the electroacupuncture and music electroacupuncture groups, point Baihui was connected to the anode and point Taiyang to the cathode, 2 voltage was used as a selection parameter and electroacupuncture lasted 30 min. Intracerebral perifocal ferric ions and neuronal apoptosis and the brain water content were measured at four time points of 6 hrs, 24 hrs, 3 days and 7 days after model making.Results Intracerebral ferric ion content was higher in the model, electroacupuncture and music electroacupuncture groups of rats than in the normal group at 6 hrsafter model making (P<0.05), lower in the electroacupuncture and music electroacupuncture groups than in the model group at 24 hrs, 3 and 7 days after model making (P<0.05) and lower in the music electroacupuncture group than in the electroacupuncture group at 3 and 7 days after model making (P<0.05). Intracerebral neuronal apoptosis was higher in the model, electroacupuncture and music electroacupuncture groups of rats than in the normal group at 6 hrs after model making (P<0.05) and lower in the music electroacupuncture group than in the electro- acupuncture group at 7 days after model making (P<0.05). The brain water content was higher in the model, electro- cupuncture and music electroacupuncture groups of rats than in the normal group at 6 and 24 hrs after model making (P<0.05), lower in the electroacupuncture and music electroacupuncture groups than in the model group at 3 days after model making (P<0.05) and lower in the music electroacupuncture group than in the electroacupuncture group at 7 days after model making (P<0.05).Conclusions Music electroacupuncture has a benign regulating effect on intracerebral perifocal ferric ions, inhibits neuronal apoptosis around hematoma in the early stage and reduces cerebral edema in rats with acute cerebral hemorrhage. Its therapeutic effect is superior to that of electroacupuncture.

Objective To observe the clinical efficacy of acupuncture with points selection based on yin-yang and qi-blood in treating insomnia by using polysomnography.Method Seventy-five insomnia patients were randomized into a treatment group of 38 cases and a control group of 37 cases. The treatment group was intervened by acupuncture with points selection based on yin-yang and qi-blood, while the control group was by oral administration of Estazolam. The polysomnography was used to assess sleep condition before and after 2 treatment courses, and the clinical efficacies were compared between the two groups.Result The sleep parameters [sleep latency, rapid eye movement (REM) latency, total sleep duration, and sleep efficiency) were significantly changed after the treatment in both groups (P<0.01). The Non-REM (NREM) and REM duration of the treatment group were significantly changed after the treatment (P<0.01). The REM duration of the control group was significantly changed after the treatment (P<0.01). After the treatment, the NREM and REM durations of the treatment group were significantly different from that of the control group (P<0.01). The sleep durations in S1, S2, S3, and S4 stages during NREM were significantly changed in the treatment group after the intervention (P<0.01). The sleep duration in S1, S2 during NREM was markedly changed in the control group after the intervention (P<0.01 ,P<0.05). After the treatment, the sleep durations in S1, S2, S3, and S4 during NREM of the treatment group were significantly different from that of the control group (P<0.01). The total effective rate was 73.7% in the treatment group versus 75.7% in the control group, and the difference was statistically insignificant (P>0.05).Conclusion Acupuncture with points selection based on yin-yang and qi-blood is effective in treating insomnia, and it can improve the sleep structure and quality.

Objective To observe the neural protective subsidiary effect of Wenyang Yiqi method on patients with severe traumatic brain injury under mild hypothermia therapy.Methods A prospective study was conducted in which 53 patients with severe traumatic brain injury treated by mild hypothermia were randomly divided into control group (26 cases) and observation group (27 cases). All the patients in the two groups received conventional western treatment combined with mild hypothermia therapy. In the observation group, additionally was given the representative drug of Wenyang Yiqi method, Shenfu injection 100 mL mixed into 5% glucose 500 mL intravenous drip once a day. At the end of mild hypothermia, the Shenfu injection was stopped. After treatment, the changes of intracranial pressure (ICP) on 1 (the day the treatment began), 2, 3, 4, 5, 6 and 7 days and the indexes levels, including S-100B, lactate dehydrogenase (LDH) and creatinkinase (CK) in the cranial spinal fluid (CSF) before treatment and 2, 4, 6 days after treament (CSF) were observed. The Glasgow coma score (GCS) before treament and 3, 5, 7, 14, 28 days after treament, and Glasgow outcome scale (GOS) on 28 days and 3 months after treatment were recorded, and the incidences of complications were calculated at the end of therapy.Results After treatment with the prolongation of therapeutic time, the levels of ICP were gradually increased in two groups and reached the peak values on the 4th day, then beganto fall, and on the 5th day it was significantly lower in observation group than that in control group [ICP (mmHg, 1 mmHg = 0.133 kPa): 16.11±1.23 vs. 18.73±1.42], persisting the same situation to the 7th day (14.17±0.80 vs. 16.94±1.00,P < 0.05). The levels of S-100 B in the two groups were progressively decreased after the treatment, on the 2nd day it was significantly lower in observation group than that in control group (μg/L: 1.21±0.43 vs. 1.86±0.57, P < 0.05), also persisting to the 6th day (0.40±0.09 vs. 0.94±0.15,P < 0.05); the levels of LDH and CK reached the peak values on the 2nd day, then began to fall, they were significantly lower in the observation group than those in the control group on the 4th day [LDH (U/L): 63.43±12.21 vs. 80.11±14.34, CK (U/L): 52.41±14.14 vs. 88.37±12.21, bothP < 0.05], and on the 6th day still there were statistically significant differences between the two groups. The GCS before treatment showed no statistically significant difference between the two groups (P > 0.05); after treatment, the GCS score of the two groups was progressively improved, and on the 14th day the score in the observation group began significantly higher than that in the control group (11.74±1.24 vs. 9.41±2.11,P < 0.05), persisting the same situation to the 28th day (12.68±2.51 vs. 10.67±1.99,P < 0.05). On the 28th day after treatment, the GOS showed no statistically significant difference between the two groups (2.35±0.16 vs. 2.43±0.22,P > 0.05), but the score in the observation group was significantly higher than that in the control group after treatment for 3 months (4.11±0.38 vs. 3.72±0.41, P < 0.05). The incidences of complications in the observation group were significantly lower than those in the control group [respiratory failure: 25.9% (7/27) vs. 50.0% (13/26), shock: 18.5% (5/27) vs. 53.8% (14/26), acute pulmonary edema: 14.8% (4/27) vs. 30.8% (8/26), stress ulcer: 22.2% (6/27) vs. 57.7% (15/26), hypoproteinemia: 40.7% (11/27) vs. 73.1% (19/26), allP < 0.05].Conclusion Wenyang Yiqi method has the subsidiary neural protective effect on patients with severe traumatic brain injury treated by mild hypothermia, and can improve their outcome.

Objective To explore the mechanism of the nerve growth factor (NGF) accommodated by electro-acupuncture in rats with diabetes peripheral neuropathy (DPN).MethodsThe rat DPN model was established with streptozotocin (STZ). The rats were randomly divided into the normal group, model group, western medicine group and electro-acupuncture group. The animals of the electrol-acupuncture group were treated with electrol-acupuncture on "Zusanli" and "Shenshu" after DPN model established. The nervous tissues of all animals were examined with the techniques of immunity and fluorescent quantitation PCR to detect the albumen and mRNA expression of NGF.ResultsThe albumen and mRNA expression of NGF of the animals in the model group, western medicine group and electro-acupuncture group were significantly lower than that in the normal group ( P<0.05～0.01), and the albumen and mRNA expression of NGF was up-regulation in the electro-acupuncture group after electro-acupuncture treatment and was significantly higher than that in the model group ( P<0.01).ConclusionElectro-acupuncture on "Zusanli" and "Shenshu" can up-regulate the albumen and mRNA expression of NGF, and improve reparation of the sciatic nerve in DPN animals.

Objective To assess the clinical value of 18F-FDG PET/CT for the prediction of postoperative recurrence and metastasis in patients with NSCLC.Methods Eighty-five patients (64 males,21 females; average age:58.0 years) with NSCLC were enrolled.All patients underwent 18 F-FDG PET/CT within one week before surgical operation and 3 months after the operation.The diagnosis of recurrent cancer and metastasis was confirmed by pathologic findings,other imaging modalities and clinical follow-up.The diagnostic efficacy of PET/CT was calculated and the predictors for postoperative recurrence and metastasis were analyzed.x2 test and two-sample t test were used for statistical analysis.Results Among 85 patients,43 had recurrence and metastasis post operation.The postoperative recurrence and metastasis were detected by 18F-FDG PET/CT in 9.3％(4/43) within 6 months,30.2％(13/43) within 1 year,76.7％(33/43) within 2 years and 97.7％(42/43) after 2 years.The sensitivity,specificity,accuracy of 18F-FDG PET/CT for the detection of recurrent tumor and metastasis were 97.7％ (42/43),95.2％ (40/42),96.5％ (82/85) respectively.The preoperative cancer staging,size and SUVmax of primary tumor were significant factors for the prediction of postoperative tumor recurrence and metastasis within 2 years (x2 =12.360,t=3.281 and 2.465,all P＜0.05),but not gender,age or pathological findings (x2 =0.639,0.012 and 3.800,all P＞0.05).Conclusions 18F-FDG PET/CT has an important role for the detection of postoperative recurrence and metastasis in patients with NSCLC.Preoperative cancer staging,size and SUVmax of the primary tumor might be the predictive factors for postoperative tumor recurrence and metastasis within 2 years.

Objective To study the curved planar reformation (CPR) imagings of bony canals in craniofacial region with multislice spiral CT.Methods CPR of the bony canals in craniofacial regions were performed in 267 cases by using Philips Mx8000 multislice spiral CT,including facial nerve canal (FNC) in 217 cases,optic nerve canal (ONC) in 28 cases,mandibular canal in 9 cases,carotid canal in 7 cases, jugular foramen in 4 cases and hypoglossal canal in 2 . Scanning parameters were as followed : 120 kV , 200~250 mAs , collimation 0.5mm, pitch 0.625 or 0.875,scan time 0.75s/ring, matrix 512?512.Collimation and reformation interval were 0.5~1.0 mm and 0.2~0.5 mm separately, except for FNC,in which were 0.5 mm and 0.2 mm separately.Reformation matrix was all 1024?1024.Results Of all cases , the images of CPR in 11 were unsatisfied because of the head shaking during the scanning, in other 256 cases , images could show the whole length of canals clearly. In FNC,178 cases were normal , 18 cases had congenital abnormal in the external , middle or inner ear accompanied with changes of length , course and position. 8 cases of otomastoiditis accompanied with cholesteatoma involving facial canal. In 21 cases of temporal bone trauma accompanied with traumatic facial palsy, fracture lines or bony fragments of the FNC were found in 9 cases. 2 cases of facial nerve tumor and 2 cases of jugular foramen schwannoma accompanied with facial canal destruction.24 cases of ONCs were normal. Fracture lines or bony fragments of ONCs were found in 3 cases. Narrowing of ONC was found in 1 cases of fibrous dysplasia.Normal carotid canal was seen in 2 cases, there were 2 cases of carotid canal fracture.1 cases of bony destruction of carotid canal caused by cholesteatoma of petrous apex. Jugular foramen was normal in 2 cases. Destruction and enlargement of jugular foramen were found in 2 cases of schwannoma. In 1 cases, hypoglossal nerve canal was normal. Destruction and enlargement of hypoglossal nerve canal were found in the other cases of schwannoma. Mandibular canal were normal in 4 cases and was involved in 2 cases by mandibular osteomyelitis and mandibular fracture,respectively, and 1 case by mandibular tumor. Conclusion The bony canals in craniofacial regions can be shown clearly by CPR with multislice spiral CT . It can provide more valuable informations than that of the axial scan and multiplanar reformation in the diagnosis of diseases of craniofacial region and was the important supplement of routine CT scan.

Objective To evaluate the clinical value of 18 F?FDG PET/CT in the diagnosis of recur?rent and metastatic endometrial cancer. Methods A total of 62 patients with endometrial cancer from October 2004 to February 2014 were retrospectively analyzed. The diagnostic efficiency of 18 F?FDG PET/CT for the de?tection of recurrent and metastatic endometrial cancer was evaluated based on the results of pathological biopsy or clinical follow?up. Results There were 28 endometrial cancer cases with recurrence and metastasis, 9 ca?ses with a second primary cancer and without recurrence and metastasis of endometrial carcinoma. PET/CT imaging had false positive findings in 3 cases, false negative findings in 2 cases. The overall sensitivity, speci?ficity and accuracy of PET/CT for detection of recurrence and metastatic endometrial carcinoma were 93.3%(28/30), 90.6%(29/32), 91.9%(57/62), respectively. The sensitivity and specificity of PET/CT for the diagnosis of vaginal stump recurrence, lymph node metastasis and distant metastasis were 9/10 and 98. 1%(51/52), 95.7%(22/23) and 92.3%(36/39), 15/18 and 95.5%(42/44), respectively. Conclusion 18F?FDG PET/CT is a useful diagnostic tool for the detection of recurrent and metastatic endometrial cancer and a second primary cancer.

Objective To investigate the imaging presentation of T-and NK/T-cell lymphomas with different pathology subtypes on 18F-FDG PET/CT.Methods A total of 95 patients (66 males, 29 females, average age 38.42 years) with T-and NK/T-cell lymphoma proved by pathology from June 2006 to February 2016 were retrospectively analyzed.18F-FDG uptake (SUVmax), nodal invasion, nodal distribution, extra-nodal involvement and staging were compared among 7 pathological subtypes of T-and NK/T-cell lymphomas.One-way analysis of variance, Fisher exact test and Kruskal-Wallis H test were used for data analysis.Results There were significant differences in terms of 18F-FDG uptake, nodal invasion, nodal distribution, extra-nodal involvement and staging among different pathological subtypes of T-and NK/T-cell lymphomas (F=2.937, P<0.05;Fisher exact test,all P<0.01;H=19.883, P<0.01).NK/T-cell lymphoma was found to be prone to invade the nasal cavity and nasopharynx, enteropathic type T-cell lymphoma was specific to the intestine, and subcutaneous panniculitis-like T-cell lymphoma presented with subcutaneous infiltration.All those 3 subtypes were quite specific in their extra-nodal involvement.Most patients with angioimmunoblastic T-cell lymphoma (ATCL), peripheral unspecified T-cell lymphoma (PUTCL) and T immunoblastic lymphoma (TIBL) presented as stage Ⅳ disease.Widespread lymph node disease associated with splenic, parotid and serous membrane involvement were often seen in ATCL patients (most commonly to involve the parotid glands and serous membrane among the 7 subtypes).Nodal involvement was found in PUTCL patients, but extranodal involvement was rather non-specific.TIBL had a non-specific pattern of nodal involvement with low 18F-FDG uptake, lower than ATCL and the other 5 subtypes.Anaplastic large cell lymphoma subtypes had the highest 18F-FDG uptake when compared with the other 6 subtypes, but were less often to manifest as stage Ⅳ disease despite their preponderance for marrow and nodal infiltration.Conclusion Different pathological subtypes of T-and NK/T-cell lymphoma manifest different imaging presentations on 18F-FDG PET/CT, which are useful for understanding their biological characteristics.
