Objective To study the clinical, histopathological and immunohistochemistric features of different types of primary cutaneous lymphomas.Methods 17 cases of primary cutaneous lymphomas were ret-rospectively reviewed.All cases were classified according to the WHO-EORTC(World Health Organization-Eu-ropean Organization for Research and Treatment of Cancer) classification system combined with morphology and immunobistochemistry.The clinicopathological features of each type were observed and summarized.Results Among the 17 cases, male were 10, female were 7.The average age was 51 years old (from 16 to 78).All pa-tients visited the doctor for skin diseases 14 cases were T-cell lymphoma including 5 cases of primary cutaneous anaplastic large cell lymphuma, 2 cases of mycosis fungoides, 4 cases of subcutaneous panniculitis-like T-cell lymphoma, and 3 cases of primary cutaneous peripheral T- cell lymphomas (including 1 primary cutaneous ag-gressive epidermotropic CD8+ cytotoxic T-cell lymphoma).3 cases were B-cell lymphoma including 2 diffuse large B-cell lymphoma, leg-type and 1 primary cutaneous follicle center lymphoma.Conclusion The clinical behaviors and pathological characteristics of primary cutaneous lymphomas were complicated and variant.Nei-ther of them could be neglected in the diagnosis.

ObjectiveTo investigate the correlation between electro-acupunctured point Houxi(SI3)and activated brain function areas, contrast the images produced with electroacupuncture at left and right points Houxi and make a comparison with electroacupuncture at point Hegu(LI4)in patients with peripheral facial paralysis.MethodPatients with peripheral facial paralysis, six on the left side and six on the right side, were enrolled as subjects. A scan of the whole brain was taken using fMRI during electroacupuncture stimulation. The images were processed using SPM software. An analysis using at-test (P<0.01) showed differences in brain functional images produced with electroacupuncture at different points.ResultElectroacupuncture at left point Houxi increased the signals of brain regions: rightcaudate nucleus, right cingulate gyrus, right parahippocampal gyrus, right superior temporal gyrus, the brainstem and the cerebellar vermis. Electroacupuncture at right point Houxi increased the signals of brain regions: right medial frontal gyrus, left middle frontal gyrus, left anterior cingulate gyrus, rightcingulate gyrus and right superior temporal gyrus.ConclusionThere is a difference in the image between electroacupuncture at point Houxi and at point Hegu or Dicang(ST4). There is also a larger difference in the image between bilateral points Houxi. The brain regions with high-frequency or low-frequency signals are not consistent. The results further prove the scientificalness of “Point Hegu is indicated for diseasesin the face and mouth” and also show that the cognominal acupoints on the two sides ofthe human body may have some differences, e.g. the conduction pathways are not completely the same and the therapeutic effects are not completely consistent.

Objective To explore the brain changes of electroacupuncturing (EA) different acupoints of peripheral facial paralysis (PFP) with functional magnetic resonance imaging (fMRI). Methods Eighteen patients with left PFP were randomly divided into three groups. Six of them received electroacupuncturing left Dicang, 6 received electroacupuncturing left Hegu, and 6 received electroacupuncturing left Houxi. fMRI data were obtained from scanning of the whole brain. Functional data were processed by SPM99 software and functional responses were established with t-test analysis (P<0.05). Results Electroacupuncturing Dicang and Hegu on the left induced decreasing of signal in bilateral middle frontal gyrus, left cingulate gyrus, signal increased of right precentral gyrus, bilateral postcentral gyrus, left superior temporal gyrus and right insular, while electroacupuncturing Houxi on the left induced decrease of signal in bilateral inferior frontal gyrus, left lentiform nucleus, right middle temporal gyrus, right cerebellar tonsil, signal increased of right caudate head, right cingulate gyrus, brainstem, cerebellar vermis and right parahippocampal gyrus. Conclusion Electroacupunctuing Hegu and Dicang can cause corresponding functional activation in cerebrum, while electroacupuncturing Houxi can not, suggesting that there is association between cerebral and acupoint of owned meridian.

AIM: To study the role of injury and phenotype shift of liver sinusoidal endothelial cells in the development of portal hypertension of liver cirrhosis in rats. METHODS: The rat liver cirrhosis model was established by peritoneal injection of dimethylnitrosamine (DMN) (at a dose of 10 mg?kg~(-1), 3 times a week, for 4 weeks). The dynamic changes of liver cirrhosis were observed at different time points (1 day, 2 days, 3 days, 1 week, 2 weeks, 4 weeks, 6 weeks and 8 weeks). The pressure of portal vein (Ppv), the expression of CD44, von Willebrand factor (vWF), endothelin-1 (ET-1) mRNA and endothelial nitric oxide synthase (eNOS) mRNA, the serum hyaluronic acid (HA) content and liver ET-1 content were measured. RESULTS: Compared with the normal control rats, CD44 positive staining was weak in the 1 day model rats, and the numbers of fenestrae of sinusoidal endothelial cells (SECs) rapidly decreased, but serum HA content rapidly increased (P

Objective To observe the effects of acupuncture therapy on triglyceride (TG) content of quadriceps femoris in the high fat diet feeding-induced insulin resistance rats; To discuss acupuncture mechanisms to improve the insulin sensitivity. Methods Thirty-two Wistar rats at the age of eight weeks were randomly divided into normal group, model group, electro-acupuncture group, and sham electro-acupuncture group. The normal group was given basic diet, and model group, electro-acupuncture group and sham electro-acupuncture group were given high fat diet for 8 weeks, after which, the model of insulin resistance was successfully obtained. Electro-acupuncture group was given acupuncture therapy with “Guanyuan (GV4)”, “Zhognwan (GV12)”, “Zusanli (ST36)”, and “Fenglong (ST40)” for 8 weeks. Sham electro-acupuncture group was given stimulation at non-acupuncture points which were not on the meridians and near the acupoints but not at the area of the acupoints. In addition, food intake and body weight of each group were recorded, blood glucose was tested, TG content of quadriceps femoris was measured by enzymatic method after the treatment. Results The weight of the rats and TG levels of quadriceps femoris in electro-acupuncture group and sham electro-acupuncture group were significantly lower than those in model group, with significant statistical difference (P<0.05), especially in electro-acupuncture group. Conclusion Acupuncture therapy could improve insulin sensitivity to prevent and its related diseases.

BACKGROUND:Hepatic fibrosis in chronic liver disease can be reversed. Studies have shown that Periplaneta americana extract has anti-fibrosis effect, and has protective effect on the experimental hepatic fibrosis rats.
OBJECTIVE:To observe the effect of Periplaneta americana extract sticky sugar amino acid on hepatic fibrosis, and to primarily explore the mechanism of sticky sugar amino acid against hepatic fibrosis.
METHODS:Rat models of immune hepatic fibrosis were induced by pig serum and intragastricaly administered 0.5, 0.25, 0.10 g/kg sticky sugar amino acid. Four indexes of hepatic fibrosis were detected by radioimmunoassay. Immunohistochemical staining wasused to measure transforming growth factor beta 1, tissue inhibitor of metaloproteinase protein expression intensity and positive cel rate, to determine the correlation of different concentrations of sticky sugar amino acid, transformation growth factorbeta 1 and tissue inhibitor of metaloproteinase.
RESULTS AND CONCLUSION:(1) The Periplaneta americana extract sticky sugar amino acid reduced the levels of laminin, type III procolagen, type IV colagen and hyaluronidase (P< 0.01) and reduced the expression of transformation growth factor beta 1 and tissue inhibitor of metaloproteinase 1 in liver tissue (P< 0.01). (2) Sticky sugar amino acid concentration and transformation growth factor beta 1 and tissue inhibitor of metaloproteinase 1 protein expression showed a significant negative correlation (|r| > 0.9). (3) Results confirmed that the Periplaneta americana extract sticky sugar amino acid can change the reversal of hepatic fibrosis. Its mechanism of action is associated with expression of transforming growth factor beta 1 and tissue inhibitor of metaloproteinase 1 inhibited by sticky sugar amino acids.

OBJECTIVE: The aim of this study was to investigate the clinical effects of sartorius tendon transposition versus sartorius transposition during bilateral inguinal lymphadenectomy of radical vulvectomy. METHODS: A total of 58 vulvar cancer patients who had surgery from May 2007 to October 2013, in which 30 patients received sartorius transposition and 28 patients received sartorius tendon transposition. All patients were matched by age, body mass index, stage, histology, and grade. Intraoperative variables and postoperative complications, recurrence, progression-free survival (PFS), and overall survival (OS) and postoperative life quality were compared and analyzed. RESULTS: No significant differences were found at median surgical times and amounts of bleeding (p=0.316 and p=0.249, respectively), neither at the incidences of groin cellulitis and lymphocele (p=0.673 and p=0.473, respectively), but the recovery times of the inguinal wounds were shorter (p=0.026) and the incidences of wound break and chronic lymphedema were significantly decreased in the tendon transposition group (p=0.012 and p=0.022, respectively). Postoperative quality of life in tendon transposition group was significantly improved as indicated by the EORTC QLQ-C30 questionnaire. Recurrences were similar (p=0.346) and no significant differences were found at PFS and OS (p=0.990 and p=0.683, respectively). CONCLUSION: Compared to sartorius transposition, sartorius tendon transposition during inguinal lymphadenectomy led to improved patient recovery, reduced postoperative complications, and improved life quality without compromising the outcomes.
