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.

Objective To discuss the clinicopathological characteristics of cervical cancer patients with lymphatic metastasis, to evaluate lymph node metastasis in cervical cancer patients by combining pelvic MRI enlarged lymph nodes and SCC-Ag, and to analyze the prognostic value of the model. Methods We retrospectively analyzed the data of 124 patients with cervical cancer. The predictive model was established based on the result. Results The depth of interstitial infiltration, serum SCC-Ag change value before and after treatment, lymph node enlargement showed by pelvic MRI, D2-40 and Ki67 were independent risk factors for lymph node metastasis of cervical cancer (P < 0.05). The prediction model of lymph node metastasis: L=the serum SCC-Ag change value+7.127×lymph node enlargement showed by pelvic MRI+5.386×D2-40+5.135×the depth of interstitial infiltration+19.457×Ki67; the sensitivity was 78.6% and specificity was 79.2%. Conclusion The cervical cancer patients with L≥20.8261 should be noticed. Doctors should give them individualized neoadjuvant treatment, and ensure adequate surgical scope. The above lymphatic prediction model has predictive value for preoperative lymph node metastasis.

Objective To investigate the effect of infection on the expression of substance P(SP) and Th1 cytokine on colonic mucosa in patients with irritable bowel syndrome(IBS).Methods Mucosa biopsy samples were obtained in descending colon and rectum from 77 patients(20 post-infective-IBS cases)and 30 controls by colonoscopy.The expressions of SP,interleukin(IL)-2,interferon(IFN)-?were determined by immunohistochemical staining.Results Compared with controls,expressions of SP,IL-2 and IFN-?were significantly increased in IBS patients with diarrhea-predominant(P＜0.05),and expression of SP in post-infective-IBS patients with cytokines positive(IL-2 and IFN-?)were also signifi- cantly increased(P＜0.05).There were no significant differences between non post-infective-IBS and controls.Conclusions Expression of SP was significantly increased in post-infective-IBS.SP upregulated the expression of Thl cytokines(IL-2 and IFN-?).Gastrointestinal infection may involve in the patho- genesis of IBS through neuroimmune mechanism.

BACKGROUND: A pathogenesis of skin-homing lymphoid cells in primary cutaneous T-eell lymphoma(CTCL) has not been elucidated, CLA(cutaneous lymphocyte-associated antigen) defined by HECA-452 monoclonal anfibody has been proposed as the novel skin-homing receptors of infiltrative lymphocytes in atopic dermatitis and graft-versus-host disease. Accordingly, CLA may be a determinant explaining about the skin-homing properties of lymphoid tumor cells in CTCL. OBJECTIVE: This study was conducted to investigate the immunohistochemical expression of CLA in the lesional tissue specimens of cutaneous lymphomas. METHODS: Immunohistochemicslly, we examined the expression of CLA, E-selectin, ICAM-1 and LFA-1 antigens in the tissue specimens taken from the skin lesions and lymph nodes of the 22 patients with cutaneous lymphomas and the 20 control subjects with non-cutaneous lymphomas. Results : 1. The expression rate of CLA was 40.9% in the skin specimens of cutaneous lymphomas. We could not fad any expression of CLA in non-cutaneous lymphomas. 2. CTCL showed a more frequent expression of CLA(80%) than cutaneous B-cell lymphomas (CBCL)(8.3%). We found more frequently CLA+ high endothelial venules in non-cutaneous lymphomas(40%) than in cutaneous lymphomas(9.1%). 3. CLA and E-selectin were more frequently expressed in primary CTCL(100%, 83.3%) than in secondary CTCL(50%, 0%). 4. The positivity to ICAM-1 and LFA-1 antigens was higher in primary cutaneous lymphomas (72.7%, 81.8%) than in secondary forms(9.1%, 9.1%). Conclusion : CLA and E-selectin may represent the pivotal skin-homing receptor of infiltrative tumor cells and vascular counter-receptor in primary CTCL, respectively. Also, ICAM-1 and LFA-1 may have a role in the primary cutaneous infiltration of lymphoma cells as the additional cofactors.

BACKGROUND: Antiphospholipid antibodies(APA) including anticardiolipin antibodies(ACA) are significantly associated with ulcerations of the leg. Moreover, resistance to activated protein C(aPC) may be an important risk factor in leg ulcerations. Until now, there has been no clinical investigation about the positivity of APA or resistance to aPC in patients with leg ulcers in Korea. OBJECTIVE: We investigated the positivity to APA and the presence of resistance to aPC in patients with leg ulcers in Korea. METHODS: Venous or arterial ultrasonic Doppler, semiquantitative assay for serum APA and functional analysis for aPC resistance were conducted in 32 patients with leg ulcers. RESULTS: 1. Of the 32 patients with leg ulcers, 34,3% had a positive APA. APA were more frequently associated with venous ulcerations of the leg than in subjects with leg ulcers of arterial or mixed origin. 2. aPC resistance based upon the functional analysis, occurred in 43.7% to 46.8% of leg ulcer patients. 3. Livedo reticularis (38.1%) and superficial thrombophlebitis (19.0%) were the most common cutaneous manifestations accompanied by leg ulcers in 21 APA-positive and/or aPC resistant patients. Deep vein thrombosis of extremities was the most common complication (47.6%) among the systemic thrombotic sequelaes in APA-positive and/or aPC resistant patients. CONCLUSION: APA positivity and aPC resistance may be relatively common anticoagulant defects among patients with leg ulcerations in Korea. APA positivity and aPC resistance should be considered important risk factors for the development of not only leg ulcers but also systemic thrornbotic complications.

objecfive To know and compare the intelligence level of children born in different time periods in regions with iodine deficiency disorders(IDD)in Liaoning province.Methods All 7-14 year-old children from ten schools were chosen as the subjects respectively from six villages in each of the six counties and in regions with iodine deficiency,who were respectively born at the initialization of iodinated salt supplying period(1978-1980);non-iodinated salt supplying period(1981-1990);recovery of supplied iodized salt period(1991-1995);universal iodized salt period(1996-2000),respectively.Intelligence quotient(IQ)was measured by Combined Ravens Test in China(CRT-C)and Combined Ravens Test-the Rural,in China,2nd edition(CRT-RC2).Results IQ of children during the non-iodized salt period(91.9±14.3)was significantly lower than the initial supply of iodized salt period(95.8±14.6,q=8.60,P<0.01),recovery of supplied iodized salt period(99.7±14.7)was significantly higher than the initial supply of iodized salt period, non-iodized salt sales period(q = 9.53, 18.13, all P < 0.01 ),universal salt iodization( 104.3 ± 14.9) was significantly higher than the initial supply of iodized salt period, non-iodized salt sales period, recovery of supplied salt iodization(q = 20.00,28.00,10.46, all P < 0.01). Children's rate of mental retardation (IQ≤69) was higher in non-iodinated salt supplying period (6.7%, 88/1314 ) than the initial supply of iodized salt (4.4%, 21/471, χ2 = 3.85, P < 0.05), recovery of supplied iodized salt period(3.3%,48/1470) was significantly lower than non-iodinzed salt supplying period (χ2 = 15.37, P < 0.01), universal salt iodization period(2.7%, 36/1344) was lower than the initial supply of iodized salt period(χ2 = 4.41, P < 0.05) and non-iodinzed salt supplying period(χ2 = 26.34, P < 0.01 ). The IQ and intelligent retarded rates in children born during the initial years of iodinated salt supplying period were not different. The IQ of the children during ten years of non-iodized salt supplying period fluctuated in a "∪" curve, while the intelligent retardation rates in a "∩" curve.The children born during the period of recovery supplied iodized salt increased their IQ and lowered the retardation rates year after year. The IQ of the children in universal iodized salt period kept on increasing while intelligent retarded rates reduced to the lowest level. Conclusions The intelligence level of children born in regions with IDD during non-iodized salt supplying period is remarkably lower than that of the beginning years of iodinated salt supplying period. The intelligence level of children born after universal iodized salt period is remarkably higher than that of the initial iodinated salt supplying period and recovery of supplied iodized salt period, respectively.

OBJECTIVETo make multi-central clinical valuation of SHAO's "five needling methods" for treatment of asthma of deficiency of lung and spleen.

METHODSTwo hundred and ten cases were randomly divided into a test group and a control group, 105 cases in each group. The test group were treated with SHAO's "five needling methods", with Feishu (BL 13), Dazhui (GV 14), Fengmen (BL 12) selected; the control group were treated with routine needling method, with Dingchuan (EX-B 1), Gaohuang (BL 43), Feishu (BL 13), Taiyuan (LU 9), Pishu (BL 20), etc. selected. The treatment in the two groups was given once each day, for 4 weeks, with one-day interval each 6-consecutive day.

RESULTSFourteen cases were clinically cured, 42 cases were markedly effective, 32 cases were effective and 6 cases were ineffective in the test group with an effective rate of 93.6%; and 8, 30, 41 and 13 cases in the control group, respectively, with an effective rate of 85.9%, with a significant difference between the two groups (P < 0.05). After treatment, the symptoms and signs, pulmonary function in the test group were better than those in the control group (P < 0.05).

CONCLUSIONSHAO's "five needling methods" has significant therapeutic effect for treatment of asthma of deficiency of lung and spleen, which is better than that of the routine needling method.
