Objective: To observe the difference of the effect of low-frequency electroacupuncture (EA) on blood lipids between male and female patients with simple obesity due to damp induced by spleen deficiency. Methods: Eighty patients with simple obesity were recruited, including 37 males and 43 females, to receive low-frequency EA by selecting Yinlingquan (SP 10), Sanyinjiao (SP 6), Zusanli (ST 36), Fenglong (ST 40), Quchi (LI 11), Tianshu (ST 25), Zhongwan (CV 12), Shuifen (CV 9), Qihai (CV 6) and Guanyuan (CV 4), with needles retained for 30 min. The treatment was given once a day, 10 sessions as a treatment course, for 2 courses in total. The contents of body fat percentage (F%), total cholesterol (TC), triglyceride (TG), high-density lipoprotein (HDL), low-density lipoprotein (LDL), blood glucose (Glu) and adiponectin (ADPN) in serum were observed to see the changes, and the two groups were compared and analyzed. Results: After the treatment, F%, and serum contents of TC, TG, LDL, Glu and ADPN dropped significantly in the two groups (P<0.05 or P<0.01) and the serum content of HDL increased significantly in male group (P<0.05). The decrease of F% in female group was more significant than that in male group (P<0.01); the decrease of ADPN in male group was more significant than that in female group (P<0.05). Conclusion: EA can regulate the disordered blood lipids in male and female patients with simple obesity, with certain differences between genders. The decrease of subcutaneous fat content is more significant in females than that in males, while the decrease of ADPN is more significant in males.

This study was aimed to improve the transfer rate of sinomenine in the intermediate product of Caulis Sinomenii in order to optimize the purification process of intermediate product ofCaulis Sinomenii fromTong-An (TA) injection. The transfer rate of sinomenine and the stability of fingerprints in the intermediate product of Caulis Sinomenii were used as indexes for the investigation on the impact from different pH ofCaulis Sinomenii extract before extraction. The transfer rate of sinomenine was used as an index for the investigation on the impact by different pH of hydrochloric acid created to dry extract solution. The transfer rate of sinomenine was used as an index for the investigation of four separation ways, which included the vacuum filtration, plate and frame filters, high-speed tube separator, and flat direct centrifuge, on the liquid separation of sinomenium acutum acid. The results showed that the pH ofCaulis Sinomenii extract before extraction was 10-11; the transfer rate of sinomenine was the highest in the extraction process and the fingerprints of TA injection was stable. The pH of hydrochloric acid was 2.0-2.5; and the highest transfer rate of sinomenine in acid dissolution process was 92.94%. The high-speed tube separator had the best separation to sinomenium acutum acid-dissolving liquid. The highest transfer rate of sinomenine was 93.34%. It was concluded that the optimized process can effectively improve the transfer rate of sinomenine in the intermediate product ofCaulis Sinomenii. Meanwhile, fingerprints of the product were stable. The process was simple with good repeatability.

Objective: To investigate the effect of moxibustion at Shenque (CV 8) on fatigue in rats with chronic exercise-induced exhaustion. Methods: Thirty male Sprague-Dawley (SD) rats were randomly divided into a blank group, a model group and a moxibustion group, 10 rats in each group. Except rats in the blank group, the remaining rats were subjected to create long-term exhaustion models by repeated swimming. After successful modeling, rats in the moxibustion group received mild moxibustion at Shenque (CV 8) for 15 min, once every other day with a total of 10 times. Rats in the model group and the blank group did not receive moxibustion. At the end of the treatment, the exhausted times, and the body weight of rats before and after the experiment were compared among groups. The levels of blood malondialdehyde (MDA) and urea nitrogen (BUN), as well as the activities of aspartate transarninase (AST), alanine aminotransferase (ALT) and lactate dehydrogenase (LDH) were also measured by the automatic biochemical analyzer, 24 h after the exhausting excise. Results: The 10th swimming time was significantly longer in the moxibustion group than that in the model group (P<0.01). The increase rate of the body weight was lower in the rats of the moxibustion group than that in the model group before the 7th and the 10th exhausting excise (P<0.05, P<0.01). The levels of serum MDA and BUN, as well as the activities of AST, ALT and LDH in the model group were higher than those in the blank group (all P<0.01). The levels of serum MDA and BUN, as well as the activities of AST, ALT and LDH in the moxibustion group were lower than those in the model group (P<0.01). Conclusion: Moxibustion at Shenque (CV 8) can decrease the serum levels of MDA and BUN, as well as activities of AST, ALT and LDH in the long-term fatigue rats, thus to improve the symptoms of fatigue.

OBJECTIVEConditioned taste preference (CTP) is a taste learning reflex by which an animal learns to prefer a substance which tastes not well and has been studied with much interest in recent years. However, the neural substrates of CTP are less known. This study aimed to determine the possible neural path- ways of CTP and whether serum leptin level and the leptin receptor (OB-Rb) in the hind brain are involved following CTP formation.
METHODSWe established CTP of quinine in rats with a 2-bottle preference test. The serum leptin concentrations were detected, the expression of c-fos in the rat brain was tested to determine the nuclei in relation with establishment of CTR Finally, the OB-Rb mRNA expression was examined by RT-qPCR assay in parabrachial nucleus (PBN) and the nucleus of the solitary tract (NST) of the hind brain.
RESULTSCompared with control group, the level of serum leptin was higher in the CTP group (4.58 ± 0.52 vs 1.67 ± 0.25 µg/L, P < 0.01); increased c-fos positive cells were found in the anterior hypothalamus (AH, 221.75 ± 4.96 vs. 178.50 ± 6.63 cells/mm², P < 0.05), the basal lateral amygdala (BLA, 70.75 ± 6.17 vs 56.50 ± 3.62 cells/ mm², P < 0.05) and the nucleus of the solitary tract (NST, 41.25 ± 1.32 vs 32.50 ± 1.02 cells/mm², P < 0.05). But in ventromedial nucleus of the hypothalamus (VMH, 20.75 ± 2.73 vs 38.5 ± 1.54 per 1 mm², P < 005), PBN (21.50 ± 2.24 vs 36.25 ± 1.49 cells/mm², P < 0.05) and the central nucleus of the amygdala (CeA, 22.25 ± 1.53 vs 35.50 ± 2.11 cells/mm², P < 0.05), the number of c-fos positive cells was decreased in the CTP group. In addition, we found OB-Rb mRNA expression in PBN of CTP group rats was higher than that of control group (0.95 ± 0.055 vs 0.57 ± 0.034, P < 0.05), while there was no significant difference of OB-Rb mRNA expression in NST between the two groups.
CONCLUSIONNuclei AH, BLA, NST, VMH, PBN and CeA participate in the formation of CTP. Leptin and its receptor in PBN may be involved in the formation and maintenance of CTP.

AIMTo approach the protective effect of low dose gentamicin against high ototoxic dose of gentamicin.
METHODSThe guinea pigs were randomly divided into four groups: control group, low dose group, low dose protective group and high dose group. Each group received multiple intraperitoneal injections of gentamicin sulphate within different durations. Auditory brain stem response (ABR) was examined one day previous to the first and 24 h after the final injection respectively. The bulla was taken out so that the content of NO, MDA and the activity of LDH in cochlear were determined.
RESULTSThe threshold of ABR was significantly lower in low dose protective group compared with high dose group (P < 0.01). The content of NO (15.86 +/- 1.98 nmol/mg pro) and MDA (19.14 +/- 0.96 nmol/mg pro) in homogenate of high dose group was significantly higher than that of control group, low does group and low does protective group (P < 0.01). The increase of the content of NO and MDA induced by high dose GM could be significantly decreased by low dose GM administration previous to high dose injection (P < 0.01). The activity of LDH in homogenate of high dose group was significantly higher compared with control group, low dos group and low dos protective group (P < 0.01). There was no statistically significant difference of content of NO and MDA among control group, low does group and low does protective group.
CONCLUSIONThe protective effects resulting from previous low dose administration to high dose injection of GM may be related to the decrease of content of NO and MDA and activity of LDH both of which induced by high dose GM.

Objective To observe the changes of magnetoencephalography (MEG) during stretching and flexing forefinger in one hemiplegic patient before and after rehabilitation training.MethodsThe cerebral electromagnetic wave of one hemiplegic patient during stretching and flexing both forefingers was recorded by MEG and superposed with magnetic resonance imaging (MRI) to form magnetic source imaging (MSI). The changes of MEG before and after rehabilitation training were analyzed.ResultsThere was no movement evoking magnetic fields in right hemisphere motor cortex at two MSI detections, but detected in left hemisphere motor cortex. The latent period of the first and the second detection was -34.2 ms and -61.7 ms respectively. The exiting motor cortex was located in precentral gyrus. The exiting motor cortex at the second detection was located more front medial and low than at the first detection. The volume of the exiting motor cortex (9569.6 m3) at the second detection was more larger than the first detection (2309.7 m3). There was no movement evoking somatosensory magnetic fields in right hemisphere motor cortex at first MSI detection, but found at the second detection, the latent period was 91.1 ms, and the exiting cortex was located in postcentral gyrus.ConclusionThe cortex somatosensory function of patient with stroke recovers early than the motor function and the uninjured hemisphere function can improve obviously after rehabilitation training.
