Objectives To compare clinical manifestations and electrophysiological features in patients with chron?ic inflammatory demyelinating polyneuropathy (CIDP) and Type-I Charcot Marie Tooth Disease (CMT-I) for guiding dif?ferential diagnosis. Methods Data including clinical manifestations and electrophysiological indexes was collected from thirty-one CIDP cases and 28 CMT-I cases. Correlation analysis was used to assess the association of the severity of electrophysiology with the severity of clinical symptoms. Results There were statistically significant differences in onset site, sensory dysfunction, foot deformity and cerebrospinal fluid protein between these two groups (P<0.05). There were significant differences in indexes of nerve conduction and needle electromyography between these two groups (P<0.05). The severity of clinical symptoms was not related with the severity of electrophysiology in CMT-I group (r=0.27,P>0.05). Conclusions Differential diagnoses of CIDP and CMT-I can be made based on clinical manifestations and electro?physiological features.

OBJECTIVETo explore the effect of berberine on lipid metabolism disorder and lipid deposition in liver cells of non-alcoholic fatty liver disease (NAFLD) rats induced by high fat diet.

METHODSAfter one week adaptable feeding, 45 SPF level male SD rats were randomly divided into 3 groups, the normal control group, the model group, and the berberine group, 15 in each group. Except those in the normal control group, all rats were fed with high fat diet to prepare NAFLD model. As for rats in the berberine group, Berberine Hydrochloride was administered by gastrogavage. HE staining and oil red O staining were performed to identify the model after 8 weeks. Hepatocytes were isolated, and their activities and purities were tested by Typan blue staining and flow cytometry (FCM). Serum levels of TC, TG, HDL-C, and LDL-C were detected using automatic biochemical analyzer. mRNA expression levels of LXRα and FAS in liver cells were analyzed by Real-time quantitative polymerase chain reaction (PCR). Protein levels of LXRα and FAS in liver cells were examined by Western blot.

RESULTSThe NAFLD rat model was successfully established by high fat diet. The yields of purified liver cells in each rat were (6.0-7.5) x 10(8). The viability of isolated liver cells with purity over 90% (tested by FCM analysis) was higher than 95%. Compared with the normal control group,the expression of LXRα and FAS at mRNA and protein levels was higher in the model group (P < 0.01). Compared with the model group, the expression of LXRα and FAS at mRNA and protein levels was obviously down-regulated in the berberine group (P < 0.01).

CONCLUSIONSLXRα/FAS signaling pathway was one of important signaling pathways of NAFLD lipid metabolism disorders. Berberine could recover hepatocyte fatty deposits in NAFLD rats by adjusting the LXR/FAS signaling pathway of hepatocytes, which might be one of important mechanisms for fighting against NAFLD.

OBJECTIVETo investigate the influence of therapeutic bloodletting at Jing-well points and hypothermia on acute cerebral edema after traumatic brain injury (TBI) in rats.

METHODSSeventy-five SD rats were randomly divided into sham-operation group (Sham), TBI group (TBI), bloodletting group (BL), mild-induced hypothermia group (MIH), and bloodletting plus MIH group (BL + MIH) (n = 15). The model of TBI was established by electric controlled cortical impactor (eCCI). The rats of BL group were bloodletting at Jing-well points immediately after injury, twice daily. While the MIH group was settled on a hypothermia blanket promptly after TBI for 6 hours, so that the temperature dropped to 32 degrees. Each of measurement was performed after 48 hours. Magnetic resonance imaging (MRI) was used to evaluate the dynamic impairment of cerebral edema after TBI (n = 3). In addition, mNSS score, measurements of wet and dry brain weight, and Evans Blue assay were performed to investigate the neurologic deficit, cerebral water content (n = 8), and blood-brain barrier permeability (BBB), (n = 4), respectively.

RESULTSMRI analysis showed that the cerebral edema, hematoma and midline shifting of rats in TBI group was more serious than other treatment group. Meanwhile compared with TBI group, the mNSS scores of every treatment group were meaningfully lower (all P < 0.05). Furthermore, treatment with BL+ MIH group was superior to the separated BL and MIH group (all P < 0.01). In addition, brain water content of each intervention group reduced to varying degrees (all P < 0.05), especially that of MIH group and BL + MIH group (P <0.01). BBB permeability of each treatment group was also significantly improved (all P < 0.01), and the improvement in MIH group and BL + MIH group was much better than the BL alone group (P < 0.05, P < 0.01).

CONCLUSIONOur major finding is that bloodletting at Jing-well points and MIH can reduce cerebral edema and BBB dysfunction and exert neuroprotective effects after TBI. The results suggest that the combination of BL and MIH is more effective than other treatment being used alone.

OBJECTIVETo observe effects of heavenly stem-prescription of point selection of the needling methods of midnight-noon ebb-flow on motorial and neurological functional deficit of ischemic cerebrovascular diseases.

METHODSThe patients were randomly divided into a Ziwu Liuzhu group and a channel acupoint selection group. In the channel acupoint selection group, Jianyu (LI 15), Quchi (LI 11), Waiguan (TE 5), Zusanli (ST 36) were selected, combined with selected acupoints by syndrome differentiation. In the Ziwu Liuzhu group, on the basis of the channel acupoint selection group, according to the principle "the acupoints of the yang-channel were opened at yang-day-yang-hour and the acupoints of the yin-channel were opened at yin-day-yin-hour", and acupoints were selected by the day-hour acupoint-opening method of the Ziwu Liuzhu Najia method in Zhenjiu Daquan. The patients in the both groups began to be treated at the Chen hour (7:00-9:00) or Si hour (9:00-11:00) in the morning, 10 times constituting one course. They were treated for 3 courses. Improvement of the motor function symptom cumulative score, Fugl-Meyer (FMA) and improvement of neurological functional deficit were investigated.

RESULTSThe FMA score (36.13 +/- 21.80) after treatment was significantly lower than (73.50 +/- 21.53) before treatment (P<0.01) in the Ziwu Liuzhu group, and (54.43 +/- 20.89) after treatment was significantly lower than (62.27 +/- 22.91) before treatment (P<0.05) in the channel acupoint selection group; the neurological functional deficit score (15.40 +/- 9.34) after treatment was significantly lower than (27.17 +/- 10.81) before treatment in the Ziwu Liuzhu group, and (23.97 +/- 1.30) was lower than (27.97 +/- 7.72) before treatment in the channel acupoint selection group. After treatment, FMA and the neurological functional scores significantly improved in the Ziwu Liuzhu group as compared with those in the channel acupoint selection group (P<0.05).

CONCLUSIONZiwu Liuzhu Najia point-selection method can effectively improve both nervous function and motor function in the patient of ischemic cerebrovascular disease.

OBJECTIVETo optimize the therapeutic programs for periarthritis of shoulder treated with acupuncture, moxibustion and kinetohterapy with orthogonal design method adopted.

METHODSThe orthogonal design table of L8 (2(7)) hierarchical principle was used to randomly divide 192 patients of periarthritis of shoulder into 8 groups, 24 cases in each one. Separately, 4 factors and each different 2 levels were adopted in treatment, named acupuncture timing (factor A: A, acute stage, A2 adhesion stage), acupoint combination (factor B: B, local acupoints, B2 local acupoints and distal acupoints along meridians), filiform needling and warm needling therapy (factor C: C1 acupuncture with filiform needle, CZ acupuncture with filiform needle and warm needling therapy) and positive functional exercise (factor D: D1 without positive functional exercise, D2 with positive functional exercise). The treatment was given once a day, 10 treatments made one session and 2 sessions were required totally. The time points of observation were the point after 1 session of treatment and after 2 sessions of treatment. The short-form McGill pain questionnaire (MPQ) and shoulder joint motor disturbance score were adopted for evaluation.

RESULTSIn the orthogonal design analysis, taking the hierarchical factors into consideration, the age was considered as the main factor in the evaluation of shoulder pain and shoulder motor disturbance (P<0.01), and the shoulder function grade apparently impacted pain evaluation and the efficacy on shoulder motor disturbance (P<0.01). The best combination of 4 factors and 2 levels were A1B1CzD2 and A2BC2D2. SAS statistical analysis showed that at acute stage and adhesion stage, CZ Dz , meaning acupuncture with fifiform needling and warm needling therapy combined with positive functional exercise, is the main factor of the improvements of shoulder motor function (P<0.05).

CONCLUSIONFor periarthritis of shoulder at acute stage, the combined therapy of acupuncture at local acupoints, warm needling and positive functional exercise is adopted. At chronic stage, the combined therapy of acupuncture at local acupoints and distal acupoints, acupuncture with filiform needle and warm needling and positive functional exercise is the best program. Additionally, in clinical treatment, the patients' age, sex, shoulder joint function and duration of treatment should be considered comprehensively for the impacts on the efficacy.

OBJECTIVETo observe the biofilm (BF) formation of Staphylococcus aureus (SA), Acinetobacter baumannii (AB) and Pseudomonas aeruginosa (PA) on the surface of deep vein catheters in burn patients after infection.

METHODSThe bacteria from deep vein catheters in 20 patients hospitalized from November 2008 to August 2009 were isolated, and were compared with their respective standard stains. Catheters tips were examined with scanning electron microscope (SEM). The semi-quantitative adhesion assay of bacterial BF was performed with modified microtiter-plate test, and the thickness of BF was scanned and measured by confocal laser scanning microscopy (CLSM) after double fluorescence staining, after being cultured in vitro for 12, 24, 48, 72 hours and 5 days, respectively. Data were processed with grouped t test.

RESULTSSix strains of SA, 8 strains of AB, and 6 strains of PA, all drug resistant, were isolated from the deep vein catheters. SEM showed that the BF structures on the inner surfaces of catheters were in diverse in their shape and degree, characterized by adherence and flake formation, and embedded in polysaccharide matrix. BF gathered in clusters, forming three-dimensional structure, in which small amount of red blood cells were found. A small number of bacteria were incompletely embedded, with some bacteria adhered to them. The absorbance values for SA after 24, 48 and 72 hours of culture (PCH) were above the cut-off value, the same for AB at PCH 12, 24, 48 and 72, and PA after PCH 48. Except for PA standard strain, CLSM showed scattered green fluorescence, mainly close to the bottom of plate, while the red fluorescence was observed in full scope at PCH 24 for each strain. At PCH 48 green fluorescence increased obviously and extended upward from the bottom, overlapping partly with red fluorescence, forming yellow fluorescence, and among the bacteria it was most obvious in AB culture, with SA the next. Compared with those of the standard stains, the intensity and quantity of fluorescence from the clinical strains were stronger; at PCH 72 the green fluorescence increased obviously especially for PA and its standard strain, while the yellow fluorescence was full of the scope for other strains. On in vitro culture day 5, the green fluorescence was dispersed and was obvious on the bottom of the plate. BF mature time for AB and SA was PCH 48, and for PA was PCH 72. The BF thickness of AB was (18.2 +/- 3.6) microm at PCH 72, which was thicker than that [(9.4 +/- 2.6) microm] of its standard strain (t = 5.42, P < 0.05), and was also the thickest among the three clinically found strains.

CONCLUSIONSSA, AB and PA, which are commonly found bacteria in burn patients, can form BF in deep vein catheters. Their ability to form BF seems to be stronger than other usually pathogenic strains, especially AB, which is the important pathogen leading to catheter related infection.
