Objective:To evaluate the knowledge and recognition of the influence factors of adverse drug reactions in medical staffs in Nanjing.Method:A structured questionnaire was used to collect information on ADR related knowledge in medical staffs in some selected hospitals in Nanjing.Result:972 valid questionnaires were obtained form 1200 selected subjects,and the response rate was 81.0%.The scores were significantly different in age groups,sex and different kinds of occupational medical workers.The mean levels of the scores were analyzed between different groups.The single factor analysis demonstrated that the different levels of hospitals,sex,knowledge and occupation were correlated with the recognition. The multiple factors logistic regression analysis demonstrated that the recognition of adverse drug reaction among medical staff in Nanjing was related with different levels of hospitals and different occupations.Conclusion:In order to enhance the recognition level,it is necessary to carry out both the long-term education and train about the specialized knowledge of ADR in basic hospitals and non-pharmacy medical staff.

Objective To study the changes of clonality of T cell receptor (TCR) and complementarity determinative region 3(CDR3) before and after autologous peripheral blood CD34+ stem cell transplantation(auto-PBSCT) for severe/refractory connective tissue disease(CTD). Methods Thirteen patients with severe/refractory CTD were enrolled for auto-PBSCT in Peking Union Medical College Hospital, including systemic lupus erythematosus (8 cases), rheumatoid arthritis(4 cases), and primary Sjogren’s Syndrome(1 case). Blood samples were collected before/after mobilization, 2 weeks, 1, 3, 6, 12 and 18 months post-transplantation. Diversity of TCRBV and CDR3 were showed by reverse transcription-polymerase chain reaction(RT-PCR) and genescan. Results The TCR BV usage and CDR3 spectral pattern of pre-auto-PBSCT CTD patients were revealed skewed pattern and oligoclonality, Which developed severe oligoclonality within 1 months after auto-PBSCT. However, they showed diversity andpoly-clonality 3～6 months after auto-PBSCT. Conclusion Skewed pattern and oligoclonality of TCRBV and CDR3 which implied auto-reactive were depressed after auto-PBSCT, and inclined to change to normal pattern.

In this work, a new method of heart sound signal preprocessing is presented. First, the heart sound signals are decomposed by using multilayer wavelet transform. And then double parameters as thresholds are used in processing each layer after decomposition for denoising. Next, reconstruction of heart sound signals could be done after processing last layer. Four methods, i.e. wavelet transform, Hilbert-Huang transform (HHT), mathematical morphology, and normalized average Shannon energy, were used to extract the envelop of the heart sound signals respectively after reconstruction of heart sounds. All methods were improved in this study. We finally in our study chose 30 cases of raw heart sound signals, which were selected randomly from a database comed from The Clinical Medicine Institute of Montreal, and processed them by using the improved methods. The results were satisfactory. It showed that the extracted envelope with the original signal has a high degree of matching, whether it is a low frequency portion or high frequency portion. Most of all information of heart sound has been maintained in the envelope.

The residents who had lived for at least 5 years and aged over 20 years old were sampled from urban to rural districts of Jiangsu Province with a stratified cluster sampling technique. B mode ultrasonography and thyroid function determination were carried out in 6 128 persons. The location, diameter, number, boundary, and calcification in thyroid nodules were described by using 7.5 MHz/50 mm transducer of thyroid ultrasonography. TSH was measured by chemiluminescence immunoassay. Free triiodothyronine(FT3)and free thyroxin(FT4)were measured when TSH was abnormal. The crude prevalence of thyroid nodules was 21.12% in total population, 14.55% in male, and 25.24% in female. The standardized prevalence was 15.69%, 11.20%, and 20.40%, respectively. The prevalence was lower in male than in female, and increased with age(P＜0.05). Thyroid nodules in Jiangsu Province were highly prevalent and more attention should be paid to the follow-up, early diagnosis, and treatment.

Objective To investigate the prevalence and epidemiologic characteristics of hypothyroidism among community population in Jiangsu province. Methods The residents who had lived for at least five years and aged more than 20 years old were sampled from six layers in urban and rural districts of Jiangsu province by a stratified cluster sampling technique. Serum was sampled from 7 122 subjects and sTSH was measured by chemiluminescence immunoassay, and FT3 and FT4 were determined in the subjects with abnormal sTSH level. Results (1) The crude prevalences of overt hypothyroidism and subclinical hypothyroidism were 0.66% and 7.53% respectively in total population, with the respective standardized rates of 0.43% and 6.28%. (2)The prevalences of hypothyroidism and subclinical hypothyroidism were significantly higher in females than in males (both P <0.05). (3) The prevalence of subclinical hypothyroidism was significantly increased with advancing age in both female and males (P<0.05). Conclusion Comparing with hypothyroidism, subclinical hypothyroidism shows higher prevalence in Jiangsu province, and more attention should be paid to the follow-up and diagnosis of subclinical hypothyroidism.

Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.
