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 investigate the expression of Slingshot-1L (SSH-1L) in peripheral blood eosinophils of asthmatic patients.

METHODSPeripheral vein blood sample of 30 ml was collected from 15 healthy volunteers, 15 asthmatic patients with glucocorticoid treatment and 15 asthmatic patients without the treatment. The eosinophils were isolated, purified and counted for each sample, and SSH-1L/beta-actin gene fragments were amplified simultaneously by RT-PCR for the total RNA. SSH-1L protein was detected by Western blotting from the total protein of the peripheral eosinophils. The expressions of SSH-1L at both mRNA and protein levels are compared between different groups.

RESULTSSSH-1L/beta-actin ratio significantly increased in untreated patients with asthma attacks in comparison with healthy volunteers (P<0.05), which did not occur in patients treated with glucocorticoids (P>0.05). The optical density of SSH-1L protein significantly increased in untreated asthmatic patients (P<0.05), but not in patients treated with glucocorticoids (P>0.05), as compared with the healthy volunteers.

CONCLUSIONSignificantly increased SSH-1L expression in peripheral eosinophils may play an important role in the activation and migration of eosinophils.

OBJECTIVETo evaluate and compare the outcome of two kinds of diameter hollow screws for the treatment of femoral neck fractures.

METHODSFrom June 2008 to June 2013, 117 patients with femoral neck fractures were treated by closed reduction and hollow screws fixation. Among them,48 patients were fixed by 6.5 mm screw including 30 males and 18 females with an average age of (45.61 ± 11.99) years old ranging from 19 to 60 years old, involving 17 cases in Garden I/II and 31 cases in Garden III/IV; 69 patients were fixed by 8.0 mm screw including 40 males and 29 females with an average age of (45.17 ± 9.95) years old ranging from 18 to 60 years old, involving 31 cases in Garden I/II and 38 cases in Garden III/IV. The general information, operative time, hospital stay time, reduction quality, diameter of femoral head and neck, fracture healing time, the rate of fracture healing, postoperative complications were recorded and evaluated. Harris scoring was used to evaluate the hip joint function.

RESULTSAll patients were followed up for 19.6 months (18 to 24 months). The difference of operative time, duration of hospitalization, quality of reduction were not statistically significant (P > 0.05). There was no difference between two groups about the average diameter of the femoral head and neck, the fracture healing time, the rate of healing and the postoperative complications (P > 0.05). There were no difference between two groups about Harris scale. There were significant difference between Garden III/IV and I /II (P > 0.05).

CONCLUSIONClosed reduction and internal fixation with hollow screw in treating the young adult patients with femoral neck fracture is the first choice, both different diameters hollow screws could meet the requirements of fixation of femoral neck fracture, and not affect on fracture healing time and postoperative complications.

To analyze the epidemiological and etiological characteristics of Hand-Foot-and-Mouth disease (HFMD) in Shanghai in 2009, epidemiological data was retrieved from the National Notifiable Disease Report System (NNDRS). Nucleic acid of enterovirus (EV) was detected by real-time RT-PCR from 799 HFMD cases from 15 districts/counties in Shanghai; the complete sequences of VP1 encoding region of several identified EV71 strains and sequences of VP4 encoding region of several untyped EV were determined and analyzed. Analysis and summary of the epidemiological data was conducted with Microsoft Excel, and sequence analyses were conducted with both BioEdit and MEGA software. Untyped EV was identified through comparing the VP4 sequence to sequence database using BLAST online service. It was showed that all the 18 districts/counties had reported HFMD cases; children less than 6 years old were the most susceptible population group; the peak of epidemics of HFMD was from April to July; EV71 and Coxsackievirus A16 (CA16) were the major pathogens for this epidemic, but the constituent ratio of EV71 and CA16 was different in different months and regions; CA16 infection was mainly responsible for the mild HFMD, but EV71 for most of the severe cases; EV71 strains of Shanghai were clustered with representatives of subgenotype C4a and showed the highest identity to them, based on the sequence analyses of VP1 encoding region; 2 of the untyped EV were identified as CA2 and CA10 respectively. All the results indicated that EV71 and CA16 were the major pathogens for the epidemic of HFMD in Shanghai, 2009; the circulating EV71 belonged to subgenotype C4a. Besides, other types of EV (for example: CA2 and CA10) were also responsible for a few of the HFMD cases.

OBJECTIVETo investigate the effect of education on self-evaluation and control level in patients with bronchial asthma.

METHODSSeventy-five asthmatic patients with the initial diagnosis in line with the American Thoracic Society criteria, including 46 with junior high school education or below (group A) and 29 with senior high school education or above (group B), were asked to complete a survey to assess their symptoms and asthma attacks. Asthma control test (ACT) and peak expiratory flow rate (PEFR) evaluation were performed 8, 12 and 24 weeks after salmeterol/fluticasone therapy. Step-down treatment was administered according to GINA guidelines. The self-evaluation of the patients was assessed according to ACT score, physical signs and pulmonary function. An ACT score over 19 indicate well controlled condition. The effect of education on the self-evaluation and control level of bronchial asthma was assessed.

RESULTSThe two groups had similar basal level of pulmonary function (FEV1). Eight weeks after the therapy, 29 patients in group A had ACT score over 19, including 11 with high control level; in group B, 17 had ACT score over 19, of whom 4 showed high control level. There was no significant difference between the two groups in control levels and self-evaluation (P>0.05). At 12 weeks, 37 patients in group A had ACT score over 19, with 17 having high control level; 22 patients in group B had ACT score over 19, 4 showing high control level; the two groups were similar in the control levels (P>0.05) but showed significant difference in self-evaluation (P<0.05). At the time of 24 weeks, 42 and 26 patients had ACT score over 19 in the two groups, with 19 and 5 having high control level, respectively. The two groups differed significantly in the control levels (P<0.05) and self-evaluation (P<0.05).

CONCLUSIONThe patients' education level may play a role in self-evaluation and control level of bronchial asthma, but its impact differs in the course of the treatment.

OBJECTIVETo investigate the expression of HMGB1 and RAGE mRNA in the lungs of asthmatic mice and the effect of N-acetylcysteine (NAC) on their expression.

METHODSTwenty-one female BALB/c mice were randomly divided into control group, asthma group and NAC group (n=7). The expressions of HMGB1 and RAGE mRNA and their distributions in the lungs were detected by RT-PCR and immunohistochemical method.

RESULTSThe expression levels of HMGB1 and RAGE mRNA were not significantly different between the control group (0.88-/+0.02 and 1.20-/+0.20, respectively) and the asthma model group (0.86-/+0.05 and 1.21-/+0.08, P>0.05). After NAC treatment, both of HMGB1 and RAGE mRNA levels (0.98-/+0.05 and 1.58-/+0.21) were significantly higher than those in the other two groups (P<0.05). HMGB1 was found in the nuclei and membrane of the bronchial and alveolar epithelial cells, and RAGE was located on the membrane of the alveolar epithelial cells.

CONCLUSIONHMGB1 and RAGE may play a role in the oxidative stress during asthma, but the exact mechanism needs further investigation.

OBJECTIVETo investigate the effect of toluene diisocyanate (TDI) on the expression of vascular endothelial growth factor (VEGF) in human bronchial epithelial (HBE) cells.

METHODSTDI-human serum albumin (TDI- HSA) conjugate was prepared using a modified Son's method. MTT assay was used to examine the viability of HBE135-E6E7 cells cultured in serum-free medium after treatment with HSA or TDI-HSA at different concentrations. VEGF mRNA expression of the HBE cells treated with HSA or TDI-HSA at 10, 20, 30 and 40 microg/ ml, respectively, was detected using semi-quantitative RT-PCR.

RESULTSTreatment with 40 microg/ml HSA and 40 microg/ml TDI-HSA did not result in significant changes in the viability of HBE135-E6E7 cells. RT-PCR revealed the constitutive expression of two VEGF isoforms, namely VEGF189 and VEGF165, in cultured HBE135-E6E7 cells. After exposure to TDI-HSA at the different concentrations (except for 10 microg/ml), a significant increase occurred in both VEGF189 and VEGF165 mRNA expressions in HBE135-E6E7 cells as compared with the expressions in the control group and the HSA-treated cells (P<0.05), and significant dose dependence was noted in the effect of TDI-HSA (P<0.05). No significant difference was found in the expressions between the control cells and the HAS-treated cells (P>0.05).

CONCLUSIONTDI induces significant increase in VEGF expression in HBE cells, and VEGF overexpression may play an important role in the pathogenesis of TDI-induced asthma.

This study is designed to test the agreement in measuring left ventricular systolic function between transthoracic two-dimensional echocardiography (2DTTE) and "gold standard" of non-invasive cardiac imaging, magnetic resonance imaging (CMRI) and their impacts on the classification of patients according to the left ventricular ejection fraction (EF). 32 patients who were suspected with heart disease were evaluated by CMRI and 2DTTE examinations. End diastolic volume (EDV), end systolic volume (ESV), EF and left ventricular function category were then calculated and compared. There was no significant difference (P=0.504) for EDV, while ESV of CMRI was significantly higher than that of 2DTTE (P=0.049), and EF of CMRI was significantly lower than that of 2DTTE (P= 0.018). There was no significant difference (P=0.077) in left ventricular functional category. Bland-Altman analysis of LV volumetric data and EF measurements showed a good agreement between two methods. The 2DTTE over-estimated I (n=5) or II (n=1) degrees of functional classification when compared with the CMRI. Both CMRI and 2DTTE are of great clinical value in evaluating left ventricular systolic function, while CMR may be more beneficial to patients with abnormal LV functions.
