Objective To explore the changes of Clara cell secretory protein(CCSP) in asthmatic children and the effects of inhaling glucocorticoid (ICS) on CCSP.Methods Sixty children with asthma were selected as asthma group(in which 39 cases were male and 21 cases were female,aged 3-12 years old) and 30 healthy children were selected as healthy control group(in which 20 cases were male and 10 cases were female,aged 3-12 years old).Venous blood samples were collected in asthma group and healthy control group in morning before breakfast,and then sera were obtained by centrifuge in speed of 1 500 r?min-1 in 10 min.The dynamic levels of CCSP were measured in sera by enzyme-linked immunosorbent assay.Results 1.In asthmatic children,the CCSP levels in acute episode,3 months after ICS,6 months after ICS, and 12 months after ICS[(5.140?2.331)?g?L-1,(8.730?3.392)?g?L-1,(10.510?2.813)?g?L-1]were all lower than that in healthy control group[(13.230?4.010)?g?L-1](Pa0.05).2.Compared with acute episode,the patients who ICS for 3 months,6 months and 12 months had significantly higher levels of CCSP (Pa0.05).Conclusions CCSP may play a protective role in the airway inflammation of asthma.Glucocorticoid may increase CCSP level in asthmatic children.Glucocorticoid and CCSP may cooperate in anti-inflammation in airway of asthmatic children.

Objective To study the clinical characteristics and curative effects of pancreatic cystade- nocarcinoma in order to improve its diagnostic and therapeutic accuracy.Methods A retrospective analysis was done on the clinical materials of 13 cases of pancreatic cystadenocarcinoma hospitalized in Shanxi Cancer Hospital from 1990 to 2006.Results The preoperative diagnosis were as follows:pancreatic cystadenocarci- noma 6 cases,pancreatic cystadenoma 2 cases,pancreatic cancer 1 case,pancreatic pseudocyst 4 cases.The misdiagnosis rate was 53.8 %.Surgical operation was done on the 13 cases,and 10 of them were treated by radical operation.A 5-year follow-up was done on 6 still alive cases,and 1 of them lived over 11 years.3 cases were treated by palliative operation,and all of them died within 3 years.Conclusion Since there is no specific clinical manifestations of pancreatic cystadenocarcinoma,it is very difficult to get an accurate preop- erative diagnosis.Radical operation is the most effective therapeutic methods.

Objective To study the survival,migration and differentiation of the neural stem cells which transplanted into ventral horn of spinal cord after brachial plexus avulsion.Methods Neural stem ceils isolated from spinal cord of neogenetic rats and cultured,expanded,labeled by BrdU before transplanted. Twenty adult healthy SD rats preformed as the model of brochial plexus avulsion(Roots C_(5～7)),then transplan- rod stem ceils into the C_6 ventral horn of spinal cord.On 1,2,4,8,12 weeks postoperatively,immunohisto- chemistry assay were carried out in the spinal cord.Results Transplanted into ventral horn of spinal cord after brachial plexus avulsion.Neural stem cells can survive,migrate for at least one segment of spinal cord and differentiate to neurons and astrocytes.The differentiation of stem cells were time-depends.Conclusion Neural stem cells can survive,migrate and differentiate after transplanted into ventral horn of spinal cord in the rats which suffered from brachial plexus avulsion.

Objective To study the efficacy and safety of tacalcitol combined with monochromatic excimer light (MEL) 308 nm vs MEL 308 nm monotherapy in treating vitiligo.Methods Thirty-eight pa- tients with vitiligo were enrolled in the single-blind clinical trial,using plabebo-treated lesions in the same patient as controls.Contralateral or nearby lesions were randomly selected to be treated by either tacalcitol or placebo.All lesions were treated weekly with MEL 308 nm,for a total of 12 sessions.Patients were ex- amined at monthly intervals.The mean number of sessions and the cumulative dosage for initial and excel- lent repigrnentation were calculated.Results Thirty-five patients were evaluated.The mean?SEM cumu- lative dose and number of MEL exposures for initial repigmentation,respectively,were 4.27?3.59 J/cm~2 and 4.89?3.16 on tacalcitol-treated site,5.36?4.12 J/cm~2 and 5.69?3.29 on placebo-treated site,re- spectively (both P＜0.05).For excellent repigrnentation,the cumulative dose and number of exposures were 7.72?5.64 J/cm~2 and 7.79?4.70 respectively on tacalcitol-treated site,and 8.18?4.87 J/cm~2 and 8.4?3.92 respectively on placebo-treated site (both P＞0.05).Treatment with tacalcitol resulted in a sig- nificantly higher percentage (71.4% vs 54.3%) of repigmentation than that with placebo.Conclusions Our results show that MEL 308 nm is safe and effective for the treatment of vitiligo.Additionally,concur- rent topical tacalcitol potentiates the efficacy of MEL 308 nm in the treatment of vitiligo;this combination achieves more rapid pigmentation with a lower total MEL dosage.

Objective To explore the role and clinical significance of interleukin-6(IL-6) in children with bronchial asthma.Methods Sera were collected from 29 cases with asthmatic attacks,32 asthmatic children who in stable conditions,and 20 health children.Serum IL-6 concentrations were measured by radioimmunoassay(RIA).Results 1.Asthmatic children appeared significantly higher levels of serum IL-6 during asthmatic attacks as compared to those in stable conditions and healthy ones respectively(P3 years old had significantly higher serum IL6 concentrations than ≤3 years old children in remission.Conclusion IL-6 may participate pathogenesis of asthma,and it may play different biological roles during asthmatic attacksas or stable conditions.

OBJECTIVETo study the clinical efficacy of Suogudan Granule (SGDG) in the treatment of rheumatoid arthritis (RA).

METHODSNinety patients with RA were randomly divided into the treated group and the control group. The treated group was administered orally with SGDG 6 g each time, thrice a day, while the control group with the combined therapy of Fenbid Capsules 0.3 g each time, twice a day and Tripterygium tablet 20 mg each time, thrice a day. The treatment course for both groups was 6 weeks. The changes of clinical symptoms and signs, and laboratory indices such as erythrocyte sedimentation rate (ESR), rheumatoid factor (RF), antistreptolysin O (ASO), routine examination of blood and urine, liver and kidney function, etc. before and after treatment were observed.

RESULTS(1) The total effective rate in the treated group (88.0%) was obviously higher than that in the control group (67.5%) with significant difference (P < 0.05). (2) The improvement in arthralgia, joint swelling, time of morning stiffness, 15-meter walking, analgesia initiation and persistence in the treated group was better than that in the control group (P < 0.05, P < 0.01), but there was no obvious difference in improvement of joint tenderness, range of joint motion, grip strength, and initiating detumescence time (P > 0.05). (3) The improvement in ESR and RF in the treated group was better than that in the control group with significant difference (P < 0.05). The negative-conversion rate of ASO in the treated group was also higher than that in the control group (P < 0.01). (4) No evident abnormality in blood, urine, liver or kidney function was found in either group.

CONCLUSIONSGDG is effective and safe for the treatment of RA.

OBJECTIVE: To investigate a nwe, simple technique for preparation of interferon-alpha-liposomes, which may be suitable for industrial use. METHODS The uniform design coupled with computerized optimization was utilized to screen the formulation and preparation procedure of interferon-alpha-liposomes. Pro-liposomes were prepared by the powder bed grinding method and combined with interferon-alpha-solution to form interferon-alpha-liposomes. Liposome size was determined by the particle size analyzer. Free interferon-alpha and interferon-alpha-liposome were separated by gel filtration. Then the recovered activity of interferon-alpha was analyzed by enzyme-linked immunosorbent assay. RESULTS The result demonstrated that the best interferon-alpha-liposome formulation was as follows: the protectant was sorbitol; weight ratio of protectant to lipid was 5:1; weight ratio of octadecytamin to lipid was 1:9; weight ratio of sobey phosphatidylcholine to cholesterol was 9:1 respectively. Interferon-alpha-liposome size determined by the particle size analyzer was 80.8+/-36 nm and the encapsulation efficiency was 59.0+/-3.3%. CONCLUSION The powder bed grinding method can be used to prepare pro-liposomes which can be easily combined with interferon-alpha-solution to form interferon-alpha-liposomes.
