During professor SHAO Jing-ming's academic research and medical practice, his academic opinion of focusing spirit is gradually developed. In terms of nurturing the spirit, attention should be paid on persistence as well as everyday health maintenance and exercise to nurture the spirit of physician. In terms of clinical diagnosis and treatment, patients' psychology, employment and life status should be observed and experienced, which could bring more methods to take essential care of patients' spirit. The treatment should work with psychological counseling, advocating that based on patients' qi and spirit, various forms of treatment methods should be properly used, such as acupuncture or moxibustion or combination of acupuncture and medicine, along with simple acupoint selection and harmony medication. Before clinical treatment of acupuncture, calming the mind is critically emphasized to make a clear diagnosis. During the acupuncture, calming and focusing the mind is necessary as well as emphasizing the details, so acupuncture could be integrated with Chi Gong to create a new warming-sensation technique. In a word, the academic opinion of focusing spirit is shedding an inspiring light upon further study.

OBJECTIVETo investigate sex difference on nutritional status, feeding practice and health care of rural children in western China.

METHODSData used in this study was from a large scale cross-sectional survey conducted in western rural areas of China. The total number of children younger than 3 years old was 14 532, in which 57.4% were boys. Logistic regression model was employed to control selected background factors for analysis of sex differential on nutritional status,feeding practice and health care of children.

RESULTSThe prevalence rates of stunting, underweight and wasting were close between both genders, regardless of north or south areas. After controlling of selected background factors, sex differentials in malnutrition happened only in north areas. It showed that boys having higher risk of being underweight than girls (OR = 1.27) in the families with one child and lower risk of being stunting than girls ( OR = 0.60). There was no sex differential found in stunting, underweight and wasting for any type of families in south areas. As for feeding practice egg was introduced to boys more frequently compared with girls,which was found in families with one child of south areas and ones with two children from the southern areas. More boys from families with two children of southern areas were exclusively breastfed within 4 months after birth. Data indicated boys had higher risk of being sick. Prevalence of anemia was 36.2% for boys,33.4% for girls. Prevalence of cold was 29.0% for boys,27.4% for girls. Prevalence of diarrhea was 19.0% for boys, 17.5% for girls. This sex differential persisted in the families of north areas after controlling for selected background factors.

CONCLUSIONSex differentials on nutritional status, feeding practice and health care exist in rural areas of western China, especially in north areas.

Objective To evaluate the effect of bone mesenchymal stem cells (BMSCs) on lidocaine-induced apoptosis in dorsal root ganglion cells (DRGCs) of rats in vitro.Methods DRGCs in the logarithmic phase were incubated in culture plates at the density of 2 × 104 cells/cm2 (27 wells in total).DRGCs were randomly divided into 3 groups (n =9 each) using a random number table:control group (group C),lidocaine treatment group (group L) and BMSC treatment group (group B).The DRGCs in group C were incubated routinely without lidocaine,while the DRGCs were incubated for 2 h with lidocaine with the final concentration of 50 mmol/L in L and B groups.The DRGCs were then incubated normally in group L.The DRGCs were then co-cultured with the BMSCs which were incubated in Transwell chambers with the density of 2 × 104 cells/cm2 in group B.DRGCs were collected at 48 h of incubation for detection of apoptosis by flow cytometry.Apoptosis rate was calculated.Results Compared with group C,the apoptosis rate was significantly increased in L and B groups (P ＜ 0.05).The apoptosis rate was significantly lower in group B than in group L (P ＜ 0.05).Conclusion BMSCs can reduce lidocaine-induced apoptosis in DRGCs of rats in vitro,indicating that BMSCs may reduce local anesthetics-produced toxicity to the peripheral nerve.

Professor Shao Jing-ming had practiced Chinese medicine for more than 80 years with rich clinical experience and exquisite acupuncture techniques. From his clinical experience, Professor Shao's clinical features can be summarized as the followings: attaching importance to the theory of meridians and collaterals, combining pattern identification and disease identification, using fewer acupoints for treatment, and using Ashi point and Hegu (LI 4) to treat goiter. He emphasized the priority and sequence in acupoint-selection and manipulation. In treatment of epilepsy, he proposed to treat it according to the situation and paid great attention to the special function of the extraordinary acupoints. During the onset, it should be managed by calming the mind and controlling the symptoms; during the remission period, acupuncture and drugs should be applied simultaneously to regulate qi-blood and yin-yang, so as to reduce the frequency of attacks. He believed that acupuncture manipulation be one of the key factors in achieving the efficacy. In treatment of the motive diseases, such as convulsions and cramps, acupuncture with static and longer needle-retaining time should be adopted to control the limb movement, to strengthen the stimulation and to obtain a long-term efficacy. Professor Shao Jing-ming's medical records range from internal medicine, external medicine, gynecology and pediatrics, listing various refractory diseases effectively treated by him. Professor Shao was a moral and erudite Chinese medicine master, and his clinical experience is worthy of inheritance and development.

OBJECTIVETo explore the intervention of baicalin on signal transduction and activating transcription factor expression of ulcerative colitis (UC) patients.

METHODSRecruited were UC patients at Outpatient Department of Digestive Disease, Inpatient Department of Digestive Disease, Center for Digestive Endoscopy of College City Branch, Guangdong Provincial Hospital of Traditional Chinese Medicine, and Southern Hospital affiliated to Southern Medical University from June 2010 to January 2011. They were assigned to the UC group (33 cases) and the diarrhea-predominant irritable bowel syndrome (IBS-D) group (30 cases). Another 30 healthy subjects were recruited as a healthy control group. Peripheral blood mononuclear cells (PBMCs) in vitro intervened by different concentrations baicalin were taken from UC patients. IL23R gene expressions in vitro intervened by different concentrations baicalin were detected using Q-PCR. Expressions of signal transducer and activator of transcription 4 (STAT4) , STAT6, phosphorylated-STAT4 (p-STAT4), and p-STAT6 were detected using Western blot. Serum levels of IFN-γ, IL-4, IL-6, and IL-10 were measured by ELISA. Effects of different concentrations baicalin on expressions of PBMCs, and levels of IFN-γ, IL-4, IL-10 of UC patients were also detected.

RESULTSCompared with the negative control group, 40 µmol baicalin obviously decreased IL23R gene expression of UC patients (P <0. 01). Compared with the healthy control group and the IBS-D group, p-STAT4/STAT4 ratios increased, p-STAT6/STAT6 ratios decreased, levels of IFN-γ, IL-4, IL-10 all increased in the US group (all P <0. 05). Compared with the negative control, 5 and 10 µmol baicalin groups, 20 and 40 moL baicalin obviously decreased p-STAT4/STAT4 ratios (all P <0. 05); 20 and 40 µmoL baicalin obviously increased p-STAT6/STAT6 ratios (all P <0. 05); 20 and 40 µmoL baicalin obviously lowered levels of IFN-γ and IL-4, and elevated IL-10 levels (all P <0. 05).

CONCLUSION40 µmoL baicalin could in vitro inhibit p-STAT4/STAT4 ratios, adjust p-STAT6/STAT6 ratios and related cytokines, thereby balancing the immunity and relieving inflammatory reactions of UC.

Objective: To evaluate the effect of docosahexaenoic acid (DHA) on microglial activation during oxygen-glucose deprivation and restoration (OGD/R) injury. Methods: N9 microglia were inoculated in 96-well culture plates at a density of 10⁴ cells/well for 3-5 days and divided into 3 groups (n=18 each) using a random number table method: control group (group C), group OGD/R and DHA+ OGD/R group. The cells were cultured for 24 h in an incubator at 37 ℃ (95% air-5% CO₂) in group C. In OGD/R and DHA groups, the culture medium was replaced by glucose-free culture medium, the cells were cultured for 12 h in an incubator at 37 ℃ (95% N₂-5% CO₂), and then cells were returned to the normal culture medium and cultured for 24 h in an incubator at 37 ℃ (95% air-5% CO₂) to establish the OGD/R injury model. The cells in group DHA were incubated with 25 μmol/L DHA at 12 h before OGD/R. The cell viability was detected using the methyl thiazolyl tetrazolium assay, the activity of lactate dehydrogenase (LDH) was measured by using chemical colorimetric method, activated microglia were counted by immunofluorescence staining, the expression of microglia activation marker iba-1 was detected by Western blot, and the concentrations of tumor necrosis factor-α (TNF-α), interleukin 6 (IL-6) and IL-4 and IL-10 in culture medium were determined using enzyme-linked immunosorbent assay. Results: Compared with the group C, the cell viability was significantly decreased, the LDH activity was increased, the number of activated microglia was increased, and the expression of iba-1 was up-regulated in OGD/R and DHA+ OGD/R groups, the concentrations of TNF-α and IL-6 were significantly increased in group OGD/R, and the concentrations of TNF-α, IL-6, IL-4 and IL-10 were significantly increased in group DHA+ OGD/R (P<0.05). Compared with group OGD/R, the cell viability was significantly increased, the LDH activity was decreased, the number of activated microglia was decreased, the expression of iba-1 was down-regulated, TNF-α and IL-6 concentrations were decreased, and IL-4 and IL-10 concentrations were increased in group DHA (P<0.05). Conclusion The mechanism by which DHA reduces OGD/R injury may be related to inhibiting activation of microglia and to reducing inflammatory responses.

OBJECTIVETo investigate the clinical indications of asthma control test (ACT).

METHODSA total of 120 asthmatic patients with a diagnosis in line with the American Thoracic Society criteria and treated for over a month were enrolled in this study. The patients were asked to complete a survey to assess their symptoms and asthma attacks, and ACT evaluation was conducted by physicians familiar with ACT evaluation. The patients were classified into two groups based on the pulmonary function test (positive for bronchodilator test and provocation test) or based on disease severity (mild and moderate-to-severe asthma groups). The effect of ACT evaluation was graded as good (no less than 4 item available for evaluation), fair (2-3 items available) and poor (no more than 1 item). To further analyze the ACT sensitivity in relation to different disease severity, 29 asthmatic patients with an initial diagnosis and BDT positivity were included, and the ACT score of the patients with mild, moderate and severe asthma based on FEV1% were compared.

RESULTSIn patients positive for bronchodilator test, good, fair and poor evaluation effects were found in 48, 15, and 5 cases, as compared to 10, 15, and 27 in those positive for provocation test, respectively, showing significant differences between the two groups (P < 0.001). In mild asthma group, good, fair and poor evaluation effects were found in 12, 15, and 18 cases, respectively, significantly different from those in moderate-to- severe asthma group (50, 21, and 4 cases, P < 0.001). ACT scores showed a positive correlation to FEV1% in 29 patients with positive BDT (r = 0.55, P = 0.003). ACT scores had no significant difference between mild and moderate asthma groups (P > 0.05), but showed significant differences between mild and severe groups (P = 0.009) and between moderate and severe groups (P = 0.008).

CONCLUSIONACT is more suitable for evaluating patients positive for bronchodilator test or with moderate to severe asthma.

A pairs of primers were designed according to the fusion protein(F)gene sequences of canine distemper virus(CDV)in GenBank.A 369 bp fragment aimed signal peptide fragment of F gene was amplified.The PCR products from viscera samples,blood,urine of fur animals including foxes,minks and raccoon dogs,which collected in the years 2005-2007,were cloned to pMD18-T Vector and sequenced.We obtained 13 positive signal peptide fragments from wild-type strains.The results indicated there was obviously genetic diversity between the wild-type strains and CDV3 and other vaccine strains.The homology with CDV3 is 80.7%-83.2%in nucleotide,and 64.8%-71.3%in amino acid.The analysis for the hydrophobic regions indicated the function of signal peptide fragment may be changed.This study can offer aca- demic data to research of CDV genetic variation and epidemiology.

This study was aimed to investigate expression of vascular endothelial growth factor mRNA (VEGF mRNA) and its relationship with leukemic cell apoptosis after VEGF antisense oligonucleotide (VEGF ASODN) transferred into HL-60 cells. The phosphorothiate VEGF ODN was transferred into HL-60 cells in vitro by using cation poly mediated method, the inhibitory rate of cell proliferation was assayed by MTT, expression of VEGF mRNA was measured by RT-PCR, cell apoptosis was detected by cell morphology observation, DNA agarose gel electrophoresis and flow cytometer (FCM). The results showed that difference of the inhibitory rate of cell proliferation and the relative expression of VEGF mRNA between ASODN group and MSODN or control groups under the same condition (p < 0.05) was statistic significant, but no significant difference (p > 0.05) was found between MSODN and control. The number of clusters of cells in ASODN group decreased; the morphology features of apoptotic cells involved cell shrinking, more granulation in cytoplasm, nuclear contracting and many fragments of cells. In MSODN and control groups, however, cells were plump and clear, and grow healthly. The result of electrophoresis revealed DNA ladder in ASODN group, while only one band of DNA in control groups. The rate of cell apoptosis was 19.46% in ASODN group with a significant difference as compared with MSODN groups and control (p < 0.05). The rate of HL-60 cell apoptosis in combination of VEGF ASODN with VP16 was significantly higher than that in VP16 alone (p < 0.05) and showed time- and dose- dependence. It is concluded that VEGF ASODN can down-regulate expression of VEGF mRNA of HL-60 cells, induces the apoptosis, inhibits the proliferation of HL-60 cells and enhances VP16-induced apoptosis in HL-60 cells, the VEGF ASODN in combination with VP16 shows additive effect.
