Objective To increase the awareness of thyroid diseases through observing the relationship between ultrasound indications of thyroid and thyroid disease,and to enhance the understanding of thyroid disease through outpatient data.Methods Two hundred women aged 25 to 50 with thyroid imaging data were selected from the Department of Ultrasonography,the First Affiliated Hospital of Harbin Medical University.Seven indications including age,body weight,thyroid volume,the number of nodules,nodule size,nature of nodules and thyroid disease were recorded.Thyroid cases were divided into four groups based on their sonographic changes of color Doppler ultrasound:normal group (136 cases):sonographic changes of thyroid were approximately normal ; mild degree group (9 cases):consisting of patients with mild thyroid disease,diffused thyroid enlargement or combined cystic nodules; moderate degree group (38 cases):consisting of patients with moderate thyroid disease,hyperthyroidism or hypothyroidism; severe degree group (17 cases):consisting of patients with severe thyroid disease,thyroiditis and/or with hemorrhage and calcification.Data were analyzed using the method of clinical case observation and SPSS 16.0.Results We found that in mild degree group the discriminant coefficients of thyroid volume,the nature of thyroid nodules and nodule size were 0.085,0.169 and 0.695; but in sever degree group the corresponding values were 0.158,0.344 and 0.484,respectively,and the difference between the two groups was statistically significant (x2 =43.3,df =18,P ＜ 0.01).Conclusions The nature,size and area of thyroid nodules are closely related to the progression of thyroid disease.The color Doppler ultrasound data of outpatients as a part of hospital statistics have important theoretical and practical value.

Objective To develop and test a stressor scale for in-patients with spinal cord injury (SSIPSCI). Methods Based on in-depth interviews and the second-level International Classification of Functioning, Disability, and Health (ICF) categories, a 39-item SSIPSCI was generated and pilot tested. It was then used with 284 inpatients with spinal cord injury. Principal components factor analysis and correlation analysis were performed.Results The exploratory components factor analysis revealed 7 significant stress factors: social activity, economy security, individual activity, relationship with others, physical disorders, bowel and bladder problems and medical fees. Internal consistency was high, with a Cronbach's alpha coefficient of 0. 950 overall and 0. 741 ～ 0. 920 for the individual factors. Test-retest reliability was 0.848. The correlation between SSIPSCI scores and Beck depression inventory (BDI) scores was strong ( r = 0. 665 ). Conclusions The reliability and validity of the SSIPSCI are both satisfactory enough to meet psychometric requirements.

Professor LI Zhi-dao's acupuncture technique at muscle belly and its clinical experiences for the treatment of arthralgia are introduced. From aspects of TCM, anatomical physiology and sports biomechanics, the theory basis of this technique is explained, while its method is elaborated in details from acupoint selection and manipulation combined with classic medical cases.

To investigate the effect of Carbomer eye gel and recombinant human epidermal growth factor (rhEGF) on dry eye after cataract surgery in diabetics.
●METHODS: A total of 160 patients ( 160 eyes ) with diabetes undergone phacoemulsification with a diagnosis of dry eyes were randomized divided into two groups, treatment group (80 cases, 80 eyes) and control group (80 cases, 80 eyes). ln treatment group, the patients were treated by Carbomer eye gel and rhEGF. ln control group, the patients were treated by Carbomer eye gel. The subjective dry eye symptoms, tear break - up time (BUT), Schirmer l test ( S Ⅰ t) and cornea fluorescein staining ( FL) were observed before treatment, 1, 4wk after treatment.
●RESULTS: There was no significant difference between groups before treatment (P> 0. 05). After treatment at 1, 4wk, the subjective dry eye symptoms and the results of three examination ( BUT, S Ⅰ t and FL) in two groups better than those before treatment ( P< 0. 01). And there was significant difference between experimental group and control group (P<0. 05; P<0. 01), the results of BUT, Slt and FL were improved in treatment group better than that in control group (P<0. 01). All patients showed good tolerance to Carbomer eye gel and recombinant human epidermal growth factor.
●CONCLUSlON: Carbomer eye gel can relieve the dry eye symptoms of diabetes after phacoemulsification effectively, and it can be more effective to combine Carbomer eye gel with rhEGF at early stage after phacoemulsification.

This study was purposed to investigate the inhibitory effect of bactericidal permeability-increasing protein (BPI) on lipopolysaccharide (LPS)-mediated activation of platelets. Venous blood samples were obtained from 10 healthy volunteers and were prepared into platelet-rich plasma (PRP, 1 × 10(8)/ml). Experiments were divided into four groups: normal platelet group (untreated group); LPS group, BPI group and BPI+LPS group. PRP were stimulated by LPS (10 µg/ml) in the presence and absence of BPI (100 µg/ml) or BPI alone. Then platelets were harvested and determined for Toll-like receptor-4 (TLR-4) with flow cytometry (FCM), the supernatant was used for detection of cytokines including tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) with enzyme-linked immunosorbent assay (ELISA). The results showed that as compared with normal platelet group, TLR-4 expression on platelets was significantly increased under LPS stimulation (P < 0.001); the levels of TNF-α and IL-6 in the supernatant were also remarkably elevated (P < 0.001). However, either TLR-4 expression or the cytokine levels significantly decreased in the presence of BPI when platelets underwent LPS-challenge (P < 0.05), but still were higher than that in normal platelet group. Stimulating the platelets with BPI alone could not enhance the TLR-4 expression and cytokine levels. It is concluded that BPI has the ability to inhibit the LPS-induced platelet activation.

OBJECTIVETo describe the characteristic magnetic resonance imaging (MRI) appearance of cerebral schistosomiasis.

METHODSTwenty-five patients whose diagnosis of central nervous system (CNS) schistosomiasis had been pathologically (n = 8) and clinically (n = 17) confirmed were randomly selected. MRI was performed on a Signal 1. 5T MRI scanner before and after the intravenous administration of gadopentetate dimeglumine constrast medium. We reviewed the MRI studies obtained at the time of initial presentation, as well as follow-up studies obtained during and after medical treatment.

RESULTSImmunological tests in 15 patients indicated schistosomiasis haematobium. Contrast-enhanced T1-weighted images in 22 cases showed central linear enhancement surrounded by multiple enhancing punctate nodules, which appeared "arborized". Through operation and pathological examination, 8 cases had the granuloma formation of schistosomal eggs extensive surrounded by inflammation and venous congestion. And 17 cases were treated with praziquantel and corticosteroid therapy. And they were followed up for 2 months by taking MRI, which turned out to be complete resolution of the enhancing structure and edema. At follow-up, all the patients' initial symptoms also resolved.

CONCLUSIONThe specified MRI enhancement pattern of cerebral schistosomiasis is common in most cases of CNS schistosomiasis, so it should be taken account into the diagnosis of cerebral schistosomiasis.

ABSTRACT:OBJECTIVE To explore the effects of Taohong Siwu Decoction on inflammatory factors and hemorheology in patients with femoral shaft fracture after surgery.METHODS 79 patients with femoral shaft fracture after surgery in the con-trol group were treated with conventional therapy while the equal number of patients in the study group were given Taohong Si-wu Decoction.The clinical curative effect,TCM syndrome,interleukin-1(IL-1),interleukin-6(IL-6),tumor necrosis factor-α(TNF-α),whole blood high shear viscosity(ηhigh),whole blood midst shear viscosity(ηmidst),whole blood low shear viscos-ity(ηlow),plasma viscosity(ηplasm),hematocrit value(HCT),white blood cell(WBC) count and sedimentation equation-K value of both groups were compared.RESULTS The total curative effects of study group and control group were 97.02% and 79.75% respectively(P <0.01).Both groups experienced a decrease in pain,swelling,ecchymosis,IL1,IL6,TNFα,ηhigh,ηmidst,ηlow,ηplasm,HCT,WBC and sedimentation equation-K value and the treatment group was more superior to the control group(P <0.05~0.01).CONCULSION Taohong Siwu Decoction can significantly inhibit the inflammatory response and improve hemorheology indexes and clinical symptom for patients with femoral shaft fracture after surgery.

Objective: To observe the changes of somatosensory evoked potential(SEP) and nitric oxide (NO) after subarachnoid hemorrhage(SAH), and the influence of Ginkgo biloba extract (EGb). Method: Rats in sham-operated group, SAH model group and EGb-treated group underwent measurement of dynamic changes of regional cerebral blood flow( rCBF),SEP and NO levels both in serum and in brain tissue within 24h after operation. Result: In SAH group, rCBF decreased immediately after operation, with no tendency to recover within 24h. The latency of SEP delayed progressively from 1h to 24h after SAH. NO levels in serum and in brain tissue decreased and increased respectively from 1h to 24h after SAH. EGb effectively antagonized the changes of above parameters. Conclusion: SEP is helpful in the judgement on brain ischemic damage after SAH. Decrease of NO in serum and increase of that in brain tissue may lead to cerebral vasospasm and ischemic brain damage respectively after SAH. EGb relieves SAH-induced brain ischemic damage by reversing the pathological alterations of NO.
