OBJECTIVETo summarize laws of acupoint selection of prescriptions for treatment of cervicogenic headache by acupuncture in modern literature.

METHODSRandomized controlled trials (RCTs) involving acupuncture and moxibustion for treatment of cervicogenic headache were recruited from CBM (1978-2012), VIP (1989-2012), Wanfang Database (1998-2012), CNKI (1979-2012), PubMed (1966-2012), EMbase (1980-2012), and Cochrane Library (Volume 4, 2012). Hand recruitment was also auxiliarily used. The frequency and percentage of common acupoints, the distribution of acupoints along 14 meridians and across each part of the body, the application of specific acupoints, and features of using prescriptions for specific acupoints were statistically described.

RESULTSTotally 37 recruited papers included 42 acupoints and 159 times. Common acupoints covered Fengchi (GB20, 28 times), Jingjiaji (EX-B2, 21 times), Baihui (DU 20, 12 times), Tianzhu (BL9, 1 times), and Ashi point (11 times). Meridians along which acupoints were used mainly covered Foot-shaoyang Gallbladder Meridian, Foot-taiyang Bladder Meridian,and DU meridian. Acupoints were mainly needled from head, neck, and upper limbs. Eight confluence points and luo-connecting point were commonest used as specific acupoints. Acupuncture prescriptions were mostly composed of multiple acupoints. Filliform needle was mainly used in acupuncture methods, followed by electro-acupuncture needle.

CONCLUSIONSModern acupuncture treatment of cervicogenic headache focuses on local specific points and acupoints along meridians. Acupoints were mostly selected from head, neck, and upper limbs by syndrome typing of Chinese medicine.

BACKGROUNDOver past two decades, vagus nerve stimulation (VNS) has been widely used and reported to alleviate seizure frequency worldwide, however, so far, only hundreds of patients with pharmaco-resistant epilepsy (PRE) have been treated with VNS in mainland China. The study aimed to evaluate the effectiveness of VNS for Chinese patients with PRE and compare its relationship with age cohort and gender.

METHODSWe retrospectively assessed the clinical outcome of 94 patients with PRE, who were treated with VNS at Beijing Fengtai Hospital and Beijing Tiantan Hospital between November 2008 and April 2014 from our database of 106 consecutive patients. The clinical data analysis was retrospectively examined.

RESULTSSeizure frequency significantly decreased with VNS therapy after intermittent stimulation of the vagus nerve. At last follow-up, we found McHugh classifications of Class I in 33 patients (35.1%), Class II in 27 patients (28.7%), Class III in 20 patients (21.3%), Class IV in 3 patients (3.2%), and Class V in 11 patients (11.7%). Notably, 8 (8.5%) patients were seizure-free while &ge;50% seizure frequency reduction occurred in as many as 60 patients (63.8%). Furthermore, with regard to the modified Engel classification, 12 patients (12.8%) were classified as Class I, 11 patients (11.7%) were classified as Class II, 37 patients (39.4%) were classified as Class III, 34 patients (36.2%) were classified as Class IV. We also found that the factors of gender or age are not associated with clinical outcome.

CONCLUSIONSThis comparative study confirmed that VNS is a safe, well-tolerated, and effective treatment for Chinese PRE patients. VNS reduced the seizure frequency regardless of age or gender of studied patients.

Depression is a serious mental illness with a high incidence. At present, we do not fully understand the specific pathological mechanisms of depression, and the efficacy of drug treatments is very limited. Recent studies have shown that epigenetic changes that occur in specific brain regions may be a key mechanism by which environmental factors to interact with individuals to influence the risk of depression. Therefore, drugs that target epigenetic regulation may become a new direction for the development of antidepressants. Histone deacetylase inhibitors (HDACi) are a class of compounds that inhibit histone deacetylase activity, which has been reported to be associated with depression; this article addresses the use of HDACi in preclinical studies, and their potential therapeutic role and limitations of use in depression.

OBJECTIVETo analyze the relationship between the expression of FasL, Perforin and Granzyme B and the development of acute graft versus host disease (aGVHD) after allogeneic hematopoietic stem cell transplantation (allo-HSCT).

METHODSThe peripheral blood mRNA expression of granzyme B, perforin, fasL from 17 patients after allo-HSCT was detected by competitive quantitative RT-PCR and the relationship between FasL, Granzyme B and Perforin expressions and clinical symptom of aGVHD was analyzed.

RESULTSThe expression level of Granzyme B, Perforin and FasL was 4.6 +/- 0.2, 4.5 +/- 0.1, 1.4 +/- 0.1 before aGVHD occurrence respectively, and was 98.7 +/- 2.5, 91.8 +/- 3.4, 61.5 +/- 2.2, after the occurrence in 14 patients (P < or = 0.05). Over expressions of Granzyme B, Perforin, and FasL during acute GVHD were detected in 13 of 14, 12 of 14, and 12 of 14 patients respectively. The upregulated expressions occurred prior to clinical symptom of aGVHD.

CONCLUSIONThe expressions of Granzyme B, Perforin, and FasL were significantly high in patients with acute aGVHD. Monitoring of the expressions, might predict the occurrence of clinical aGVHD and it severity and prognosis.

BACKGROUNDDystonia is one of the most challenging movement disorders to treat. Medications and surgeries are the two methods to control dystonic symptoms. For patients with dystonia in whom symptoms are inadequately controlled with pharmacologic measures, the use of deep brain stimulation (DBS) can improve symptoms and enhance functional capacity. The best candidate for DBS is believed to be primary generalized dystonia, especially the DYT-1 type. Here, we report 9 cases of secondary dystonia to explore the feasibility, indications and complications of DBS in the treatment of secondary dystonia.

METHODSFrom July 2003 to June 2006, nine patients with secondary dystonia underwent surgery at Beijing Tiantan Hospital. Among them, 2 were diagnosed as having tardive dystonia, 1 had posttraumatic dystonia, 3 had a history of perinatal anoxia, 1 had neonatal pathologic jaundice, and 2 had no exact contributory history; MRI showed bilateral lentiform nuclei degeneration in one patient. Six patients underwent bilateral subthalamic nucleus (STN)-DBS, two underwent unilateral STN-DBS, the other underwent left STN and right globus pallidus internus (GPi)-DBS.

RESULTSWith intraoperative microelectrode recording, the targeted nucleus was accurately localized. Tentative stimulation could decrease muscle tension to the same extent, but twisting was not obviously improved. Follow-up for 3 months to 3 years showed satisfactory results in 3 patients with tardive dystonia and posttraumatic dystonia and that Burke-Fahn-Marsden Dystonia Scale (BFMS) decreased by more than 90%. The improvement of symptoms was progressive along with time. The other 6 patients had slight to moderate improvement. None of them had severe surgery-related complications. One had lead fracture 16 months after surgery and the lead was then evacuated.

CONCLUSIONSDBS could be an ideal treatment for patients with tardive and posttraumatic dystonia. For patients with perinatal anoxia and diffuse impairment in the basal ganglia, DBS seemed not to be a good choice. STN could be an ideal target. Intraoperative microelectrode recording and mild amelioration of muscle tension are indicators of correct target location. No severe complications occurred.

OBJECTIVETo synthesize Gal-BSA-SPIO as the magnetic resonance imaging (MRI) contrast agent targeting asialoglycoprotein (ASG) receptors in the liver and observe its role in MRI detection of hepatocellular carcinomas (HCCs).

METHODSGal-BSA was synthesized by means of reductive amination and mixed with SPIO in ice bath to prepare Gal-BSA-SPIO complex. Twenty rabbits bearing VX2 liver tumor underwent MRI enhanced by SPIO (n=10) and Gal-BSA-SPIO (n=10), and the T2 values of the liver and tumor before and after the contrast imaging were measured. Fresh human normal hepatic tissues (n=3), cirrhotic tissues (n=4) and HCC tissues (n=6) were obtained and incubated with Gal-BSA-SPIO followed by Perl's Prussian blue staining to observe the distribution of ASG receptors.

RESULTSThe size of the Gal-BSA-SPIO particles was 34.4 nm. The 20 rabbits bearing VX2 tumor, with tumor size ranging from 3 mm to 12 mm, showed isointense signal in the liver and hypointense signal in the tumor on T1WI, and isointense signal in the liver and slightly hyperintense signal in the tumor on GRE T2*WI. The signal intensity of the liver decreased slightly or moderately after administration of SPIO in the rabbits, and administration Gal-BSA-SPIO resulted in obvious reduction in the signal intensity of the liver. The signal intensities of the tumors did not exhibit obvious changes after the administration of SPIO or Gal-BSA-SPIO. Histological examination revealed numerous blue iron deposits in the Kupffer cells in SPIO group and in the hepatocytes in Gal-BSA-SPIO group, but not in the tumors in either of the groups. The human liver specimens incubated with Gal-BSA-SPIO contained numerous blue iron deposits in the hepatocyte cytoplasm and cell membrane in normal liver tissue, but the deposits were reduced in the cirrhotic tissue and almost absent in the HCC tissue.

CONCLUSIONGal-BSA-SPIO can specifically bind to ASG receptors on hepatocyte membrane to improve the tumor-liver contrast-to-noise ratio.

OBJECTIVETo study the effect of testosterone propionate (TP) on the distribution pattern of calcitonin gene-related peptide (CGRP) in two types of motoneuron (Mn) pools in rats.

METHODThe double labeling of cholera toxin B subunit coupled with colloidal gold (CB-Au) retrograde identification combining with immunocytochemistry was mainly used to reveal the distribution pattern of CGRP-like immunoreactivity (CGRP-LI) and its changes in the motoneuron pools labeled by CB-Au.

RESULTTP injected intramuscularly 28 days later significantly decreased CGRP expression in Mn pool innervating extensor digitorum longus (EDL, fast-twitch), comparing with corresponding control and castration group respectively (P < 0.001), while no significant effect on Mn pools innervating soleus (SOL, slow-twitch, P > 0.05) was observed.

CONCLUSIONEDL-Mn pool is more sensitive to testosterone propionate than SOL-Mn pool in regulating CGRP expression.
