Objective To determine the clinical features,neurophysiological characteristics and cervical magnetic resonance imaging of sensory neumnopathy,and to describe the pathology of skin nerve, sural nerve and spinal dorsal columns.Methods Two patients who died from sensory neuron disease (SND)after infection of digestive tract were discussed including clinical features and ancillary tests which included neurophysiology and pathology of peripheral nerve and spinal dorsal columns.Associated documents are reviewed.Results Early ataxia,widespread sensory symptoms and global loss of deep tendon reflex were the distinctive signs of SND,which was characterized by non-length-dependent abnormalities of sensory nerve action potentials,a hallmark of ganglionopathies.The second patient showed normal cervical magnetic resonance imaging possibly because of short course of disease,while diffuse hyperintensity in the spinal posterior columns of SND was reported.Demyelination of spinal posterior columns and loss of mostly large diameter nerve fibers without regeneration clusters were the main pathological features.Conclusions The distinctive clinical features and neurophysiological characteristics of SND indicate that peripheral sensory nerve fibers are widely damaged.Pathology of spinal posterior columns confirm that central sensory pathway are impaired which allow the localization of the pathologic site to the dorsal root ganglion neurons.Cervical spinal MRI of SND are possibly normal at early phase.

OBJECTIVETo verify the clinical efficacy of acupuncture combined with auricle cutting method for treatment of blood stasis-type psoriasis.

METHODSFifty-six cases of blood stasis-type psoriasis were randomly divided into a combined therapy group, a auricle cutting group, an acupuncture group and a control group, 14 cases in each one. Based on regular treatment of TCM decoction in four groups, the combined therapy group was treated with acupuncture and auricle cutting method, and the auricle cutting group was treated with sham-acupuncture and auricle cutting, and the acupuncture group was treated with acupuncture and sham auricle cutting, and the control group was treated with sham-acupuncture and sham auricle cutting. The acupuncture was applied at Dazhui (GV 14), Feishu (BL 13), Ganshu (BL 18) and Geshu (BL 17), etc., and manipulated with routine technique; in the sham acupuncture, the needle was inserted into dermis layer so that the needles could be swung without being dropped out. In the auricle cutting, erbeixin (P1) of unilateral auricle was selected and cut by Chan needle to perform bloodletting; in the sham auricle cutting, the neighborhood approximately 0.5 cm next to erbeixin (P) of auricle was selected as cutting area. The treatment was given once a day, seven days as a treatment session for totally two sessions. Psoriasis area and severity index (PASI) before and after treatment was observed and efficacy of each group was compared.

RESULTSThe effective rate was 57.1% (8/14) in the combined therapy group, which was superior to 14.3% (2/14) in the auricle cutting group, 7.1% (1/14) in the acupuncture group and 0.0% (0/14) in the control group (all P < 0.05). The scores of PASI were all decreased in each group after the treatment (all P < 0.05), which was the most significant in the combined therapy group (all P < 0.05). After factorial analysis, the main effect was P < 0.05 in the auricle cutting, P < 0.05 in the acupuncture and P < 0.05 in interaction effect of combined therapy.

CONCLUSIONThe scores of PASI of blood stasis-type psoriasis could be effectively reduced by acupuncture, auricle cutting method and TCM decoction, among which the interaction effect of auricle cutting and acupuncture combined with TCM decoction is the most significant.

BACKGROUNDCoronal diffusion-weighted magnetic resonance imaging (DW-MRI) and apparent diffusion coefficient (ADC) values have gradually become applied (following conventional axial DW-MRI) in the renal analysis. To explore whether data obtained using coronal DW-MRI are comparable with those derived using axial DW-MRI, this preliminary study sought to assess the agreement in renal ADC values between coronal DW-MRI and axial DW-MRI.

METHODSThirty-four healthy volunteers were enrolled in the study; written consents were obtained. All subjects underwent respiratory-triggered axial and coronal DW-MRI using a 1.5-MR system with b values of 0 and 800 s/mm 2 . The signal-to-noise ratios (SNRs) of the two DW-MRI sequences were measured and statistically compared using the paired t-test. The extent of agreement of ADC values of the upper pole, mid-pole, and lower pole of the kidney; the mean ADC values of the left kidney and right kidney; and the mean ADC values of the bilateral kidneys were evaluated via calculation of intraclass correlation coefficients (ICCs) or Bland-Altman method between the two DW-MRI sequences.

RESULTSThe SNR of coronal DW-MR images was statistically inferior to that of axial DW-MR images (P < 0.001). The ICCs of the ADC values of each region of interest, and the mean ADC values of bilateral kidneys, between the two sequences, were greater than 0.5, and the mean ADCs of the bilateral kidneys demonstrated the highest ICC (0.869; 95% confidence interval: 0.739-0.935). In addition, 94.1% (32/34), 94.1% (32/34), and 97.1% (31/34) of the ADC bias was inside the limits of agreement in terms of the mean ADC values of the left kidneys, right kidneys, and bilateral kidneys when coronal and axial DWI-MRI were compared.

CONCLUSIONSADC values derived using coronal DW-MRI exhibited moderate-to-good agreement to those of axial DW-MRI, rendering the former an additional useful DW-MRI method, and causing the ADC values derived using the two types of DW-MRI to be comparable.

Objective To investigate the protective effect and the underlying mechanism of water soluble coenzyme Q10 (CoQ10)against rotenone induced injury on PC12 cells model.Methods PC12 cells were cultured with rotenone,water-soluble CoQ1 0 was added to the culture media 3 hours prior to the rotenone incubation.We determined cell viability by CCK8;reactive oxygen species (ROS)was detected by spectrophotometer;and Bcl-2, Bax,active Caspase-3,Caspase-9 and apoptosis-inducing factor (AIF)were measured by Western blotting after 24-hour rotenone incubation.Results After the treatment by rotenone,cell viability decreased significantly (P＜0.01)and ROS level increased (P＜0.01).CoQ10 could improve PC12 cell viability (P＜0.01)and reduce the level of ROS (P＜0.01).Western blotting experiments showed that CoQ10 could reduce rotenone-induced Caspase-9 (P＜0.05),active Caspase-3 (P＜0.05)and Bax (P＜0.01)expressions,increase the expression of Bcl-2 (P＜0.01),and prevent nuclear translocation of AIF (P＜0.05).Conclusion CoQ10 has a protective effect on rotenone-induced apoptosis in PC12 cells,the mechanism of which may be through scavenging ROS in cells;decreasing caspase-9 ,active caspase-3 and Bax expressions;and increasing the expression of Bcl-2 ;and preventing AIF nuclear translocation.

OBJECTIVETo observe the pathological changes and morphological alterations of ECV304 cells after the infection by herpes simplex virus type 2 (HSV-2) in vitro.

METHODSPassaged ECV304 cells were infected with HSV-2, TCID50 and morphological changes were observed by optical microscopy and tissue staining.

RESULTSOne day after HSV-2 infection, swelling, rounding, and increase of thickened cytoplasmic granules occurred in the ECV304 cells, and on day 2, cell fusion was observed with weakened nuclear staining.

CONCLUSIONECV304 cells mostly undergo necrosis after HSV-2 infection without obvious evidence of cell apoptosis.

OBJECTIVETo investigate the mechanisms for the cytopathic effect (CPE) of human cytomegalovirus (HCMV) in ECV304 endothelial-like cells.

METHODSPCR and indirect immunofluorescence were used to detect HCMV infection by examining immediate-early (IE) gene and protein expression of the virus in ECV304 cells. Phase-contrast and electron microscopies were performed to observe the morphological changes of the infected and uninfected cells, and DNA ladder analysis and flow cytometry were carried out to study HCMV-induced cell apoptosis.

RESULTSIn HCMV-infected ECV304 cells, cytopathic effects were first observed at approximately 72 h post-infection. The cells with CPE changes exhibited detachment from the monolayer, cell rounding and shrinkage. The expression of the IE gene was detected. Chromatin condensation and nuclear fragmentation along with dramatic changes of the mitochondria were observed by electron microscopy at 96 h post-infection. Cellular DNA fragmentation was observed in the infected cells, which had cells apoptotic rates of 4.1% and 45.7% at 96 h and 144 h post-infection, respectively.

CONCLUSIONHCMV can induce apoptosis of ECV304 endothelial-like cells.

OBJECTIVETo summarize the 23-year experience of laparoscopic biliary surgery in General Hospital of PLA and evaluate the application of laparoscopic surgery in the treatment of biliary diseases.

METHODSWe retrospectively analyzed the clinical data of 11 419 consecutive patients with biliary diseases undergoing laparoscopic surgery from April, 1992 and December, 2014. The disease spectrum was compared between patients treated before December 31, 2003 and those treated after the time point.

RESULTSThe 11419 patients receiving laparoscopic surgery accounted for 56.3% of the total patients undergoing biliary surgeries during the 23 years, including 4701 male and 6718 female patients with a mean age of 50.9∓13.2 years (6-93 years). Most (80.83%) of the patients received laparoscopic surgery for gallbladder stones, and 12.53% patients had the operation for gallbladder polyps. The laparoscopic operation rate was 84.81% in patients with gallbladder stones and 34.91% in patients with extrahepatic bile duct stones, but remained low in patients with biliary carcinoma. In laparoscopic operations, laparoscopic cholecystectomy was the most frequent (96.18%) followed by operations for extrahepatic bile duct stones, in which primary suture accounted for 1.38%, traditional T tube drainage for 0.90% and laparoscopic transcystic duct exploration for 0.72%. For malignant tumors, laparoscopic technique was used mainly for the purpose of exploration (0.34%). The application of laparoscopic technique in biliary surgery tended to increase after the year 2004, especially for benign gallbladder diseases and extrahepatic bile duct stones (P<0.05).

CONCLUSIONLaparoscopic technique in biliary surgery is gradually replacing the traditional open operation and becomes the gold standard for the treatment of benign biliary diseases.
