Objective To study the prognosis of neonatal hyperthyrotropinemia (HT). Methods Children with HT were followed up regularly to evaluate the growth index, thyroid function and effectiveness of treatment. Results One hundred and ninety-one neonates with serum TSH level of 5.6~10 mU/L at the screening were followed up until 24 months old. Serum TSH gradually returned to normal range in 182 cases. Serum TSH increased to be>10 mU/L in 5 cases who were treated with levothy-roxine sodium. Serum TSH lfuctuated between 5.6 and 10 mU/L in 4 cases who were continually followed up. Among 44 cases of serum TSH at 10~20mU/L, serum TSH gradually returned to normal range after levothyroxine sodium treatment in 38 cases;se-rum TSH increased to>20 mU/L in 7 cases for whom continuous treatment with levothyroxine sodium was required. In 242 cases of HT neonates, 18 cases had received continuous levothyroxine sodium replacement treatment for 2 years and were followed-up continuously. Conclusions Most of the newborns with HT recover within 2 years, while a few develop thyroid dysfunction and require follow-ups.

The amount of acupuncture treatment refers to the sum of acupuncture effects during the treatment. From the factors that constitutes the amount of acupuncture treatment, including the numbers of needling, the size of acupuncture instruments, the depth of acupuncture, the manipulation, the retained time of needle, etc., and combined with teaching and clinical experience, it is believed that the amount of acupuncture treatment is closely related with clinical efficacy, besides, moderate amount of acupuncture treatment is a key factor to improve acupuncture efficacy and guarantee the safety of acupuncture. The basic principles of regular treatment amount are arrival of qi and being moderate, indicating the retained time of needle, treatment frequency and course should be based on individual condition, time, location and disease.

Objective To investigate the dynamic variation of flavonoids contents in the flowers of Citrus grandis at different flowering periods. Methods The content of total flavonoids in the flowers of Citrus grandis was determined by means of ultraviolet-visible absorption spectroscopy ,and the contents of naringin and rhoifolin were determined by HPLC. Results The content of total flavonoids in the flowers during the flower withering period ,the young fruit period ,the blossom period,and the budding period was 306.90 mg.g-1,277.93 mg.g-1,215.55 mg.g-1 and 162.74 mg.g-1 respectively. The naringin content during the above four different periods was 246.31 mg.g-1,213.93 mg.g-1,175.94 mg.g-1 and 130.90 mg.g-1 respectively. The rhoifolin content during the four periods was unchanged. Conclusion The contents of total flavonoids and naringin in flowers of Citrus grandis during flower withering period are the highest.

Objective To study clinical characteristics in patients of systemic lupus erythematosus (SLE)with cardiac involvement and to assess relevant risk factors contributed to it.Methods Totally,239 patients of SLE were evaluated by cardiogram,echocardiogram and serologic examinations,and those with cardiac involvement were compared to those without it by clinical and laboratory data.Results There were 114 of 239(47.7%)SEE patients with cardiac abnormalities,of whom only 31(27.2%)had cardiac symptoms,including 44 cases(38.6%)with hydropericardium,32(28.1%)with myocardial damage,14 (12.3%)with cardiac valvular lesions,19(16.7%)with cardiac block,and 13 with other cardiac damages.No significant difference in age,gender,course of disease,SLE activity index(SEEDAI)scores,serum levels of auto-antibodies and complement(C3),and so on,were found between 114 SLE patients with cardiac abnormalities and 64 without it,who were:randomly selected from 125 patients of SEE without cardiac damage.But,patients of SLE complicated with pericarditis or myocardial lesions had higher SLEDAI scores and lower serum level of C3 than those without cardiac lesions(both P＜0.05),and relatively longer course of disease was found in those with valvular heart disease.Conclusions Cardiac damage was common in patients with SLE,but most of whom were asymptomatic,and only those with severe and active illness tended to develop pericarditis and myocardial damage and those with longer course were liable to have valvular heart disease.

Objective To determine the level of monocyte chemoattractant protein-1 (MCP-1) in patients with systemic lupus erythematosus (SLE) and to assess its relationship with disease activity and organ damage. Methods The plasma levels of MCP-I were measured by enzyme linked immunosorbent assay (ELISA) in 95 patients with SLE and 21 healthy controls. Disease activity in SLE patients was assessed using the SLE Disease Activity Index (SLEDAI). Results Plasma level of MCP-1 was significantly elevated in SLE patients than in healthy controls [(849±289) pg/ml vs (426±266) pg/ml, P<0.01]. Moreover, level of MCP-1 was significantly higher in SLE patients with lupus nephritis (LN) than in patients without LN (P<0.01), andin SLE patients with neuropsychiatric symptoms than in patients without neuropsychiatric involvement (P< 0.01). In addition, significant correlation between plasma MCP-I levels and the SLEDAI was observed (r= 0.3699, P<0.01), and this relationship was not influenced by the treatment with glucocorticoid and cyclophosphamide. Conclusion MCP-I may play an important role in the pathogenesis of SLE, including renal and neuropsychiatric involvement. MCP-I is also a serologic marker of disease activity in patients with SLE, and its measurement in SLE patients may be useful for the evaluation of disease activity.

Objective To investigate the clinical characteristics of systemic lupus erythematosus (SLE) and the situation of diagnosis after onset. Methods Three hundred outpatients diagnosed with SLE were investigated in the People's Hospital, the Third Hospital of Peking University, Xinjiang People's Hospital and the Affiliated Hospital from May to July 2008, including gender, age of onset, clinical manifestations and the site of first hospitalization. Results ① In the cross-sectional study, 300 SLE patients were investigated. The male-to-female ratio was 1:13. ② The most common manifestations at onset were arthritis (46.3%), rash (34.%) and fever (32.7%). Lupus nephritis was found to occur in a significantly higher frequency in male patients than female as the initial manifestation. 60.9% patients had lupus nephritis in the first year after onset. ③ 99.1% of the patients were correctly diagnosed after visiting rheumatologists. 23.7% of the SLE patients were not correctly diagnosed for more than one year after disease onset. Conclusion Arthritis, rash and fever are the most common initial clinical manifestations of SLE. Lupus nephritis is more commonly seen in male SLE patients than female at the disease onset. The diagnosis of lupus is delayed in certain proportion of patients.

OBJECTIVETo compare the clinical effects between ginger-partition moxibustion combined with glucocorticoid and simple oral glucocorticoid for thyreoitis at subacute stage.

METHODSEighty-one patients were randomly divided into an observation group (41 cases) and a control group (40 cases). In the observation group, ginger-partition moxibustion and hormone were applied. Moxa cones were used at local ashi points, Zusanli (ST 36), Guanyuan (CV 4) and Qihai (CV 6), six cones every point, once every other day and three times a week. Besides, 24 mg methylprednisolone tablets were adopted orally every day, and in two weeks the dose was 16 mg/d, in four weeks 8 mg/d, in six weeks 4 mg/d; all the patients were observed for 8 week. In the control group, simple methylprednisolone was prescribed orally, and the dose, the usage and treatment time were the same as those in the observation group. Erythrocyte sedimentation rate (ESR), triiodothyronine (T3), thyroxin (T4) and ultra-sensitive thyroid stimulating hormone (TSH) before and after treatment were observed in the two groups, as well as fever, the pain of thyroid gland, the regression time of swelling and adverse reaction.

RESULTSThe time of thyroid gland pain relieved of the observation group was earlier than that of the control group [(3.07 ± 0.78) days vs (3.62 ± 0.92) days, P < 0.05]. After treatment, T3, T4 and ESR were declined apparently (all P < 0.01), and TSH was obviously increased in the two groups (both P < 0.01). After 2-week treatment, ESR in the observation group was lower than that in the control group (P < 0.05). After 4-week treatment, T3, T4, TSH and ESR in the observation group were better than those in the control group (all P < 0.05). After 8 weeks, all indices in the observation group were superior to those in the control group, without statistical significance between the two groups (all P > 0.05). The effects of the observation group in 2 weeks, 4 weeks and 8 weeks were better than those in the control group (all P < 0.05). The cured course was shorter in the observation group than that in the control group (P < 0.05). The adverse reaction rate in the observation group was lower than that in the control group [4.9% (2/41) vs 22.5% (9/40), P < 0.05]. Three months later after treatment, the cured patients were followed. There was no recrudescence in the observation group and three patients caught the disease again in the control group, but there was no statistical significance between the two groups (P > 0.05).

CONCLUSIONGinger-partition moxibustion combined with glucocorticoid achieves better effect than simple oral glucocorticoid for thyreoitis at subacute stage, and the adverse reaction is less, which presents the clinical advantages of the integration of Chinese and western medicine.

BACKGROUND:Nerve growth factor has been shown to play an important role in bone healing, but little is reported on the effect of growth factor composite scaffolds via the immediate implantation in the repair of canine bone defects. OBJECTIVE:To analyze the effect of nerve growth factor composite scaffolds via the immediate implantation for the repair of canine bone defects. METHODS:Nerve growth factor composited strontium apatite scaffolds were prepared. Canine mandibular defect models were established and divided into three groups, fol owed by implanted with composite scaffold (experimental group), strontium apatite (positive control group), or nothing (blank control group). The three-dimensional CT reconstruction and hematoxylin-eosin staining of canine mandibular bone defects were observed. RESULTS AND CONCLUSION:In the blank control group, there were few new bones surrounding bone defect. Trabecular bones spread from the defect center to the surrounding tissues in the experimental and positive control groups. The bone density, volume, thickness, and implant-bone contact were significantly increased, while the trabecular separation was significantly decreased in the experimental group compared with the positive control and blank control groups (P<0.05), and al above indicators in the positive contro group were significantly higher than those in the blank control group (P<0.05). Hematoxylin-eosin staining showed that in the experimental group, there were a large number of new bones that contacted with the surrounding bones closely, and trabecular bones arranged regularly. In the positive control group, newborn osteoid, trabeculare, and a smal amount of debris were found. In the blank control group, few new bones were connected with the surrounding bones untightly and trabecular bone arranged irregularly. These results indicate that the nerve growth factor composite scaffold can promote the bone regeneration in the canine bone defects after immediate implantation.

It is kno wn that 8-Br-cAMP is one of selective bi nding site analogues for cAMP RIIα to af fect cell growth through regulation of g ene expression.The p16,p21wafl,p53 a nd Rb are antioncogenes which affect cel l growth through control of cell cycle.T he aim of this study is to investigate t he 8-Br-cAMP effect on the expression of antioncogenes in human HXO-Rb44 cells. Methods Cultured HXO-Rb44 cells in RPMI -1 640 medium were divided into two aliquot s.8-Br-cAMP (2×10-5mol/L) was added i nto one aliquot for 24h as the experime ntal group(EG),the another aliquot witho ut 8-Br-cAMP as the control group(CG).Af ter 24h,the cell suspension was dropped onto the nitrocellulose membrane.The mR NA of p16,p21wafl,wild type(w)p53,mut ant type(m) p53 and Rb were used respec tively with biotin-labeled cDNA probes b y intact cell RNA dot blot.The immunorea ctivity(IR) of P16,P21wafl,PRb,PCN A,cdk2 and cdk4 were detected respecti vely with specific monoclonal antibodies on dot blot.ResultsThe mRNA dot blot s ignals of mp53 and protein dot blot of cdk2-IR,cdk4-IR and PCNA-IR in EG were weaker than those in CG(P＜0.05～0.01). W hile,the mRNA signals of p16,p21wafl,wp53 and Rb in EG were stronger than tho se in CG(P＜0.05～0.01).The intensity of ea ch protein dot blot was consistent with that of their RNA dot blot (except for w P53-IR and mP53-IR not to be done).Conc lusions(1)8-Br-cAMP could up-regul ate expression of antioncogenes includin g p16,p21wafl,wp53,Rb,and protein exp ression of P16,P21wafl and PRb.(2) 8-Br-cAMP could down-regulate mp53 gene expression and protein expression of cd k2,cdk4 and PCNA.The results suggest t hat 8-Br-cAMP could inhibit human HXO-Rb 44 cell growth through interfering rela ted gene expression of cell cycle.
