Objective To investigate the clinical value of multi-slice spiral CT (MSCT)in the diagnosis of focal pulmonary ground-glass opacity nodules(fGGO)of 1 cm or less.Methods The MSCT examination data of 95 patients with subcentimeter fGGO was analyzed and compared with pathology results.The different pathological types of fGGP lesion size,internal solid component size,mixed type ground glass nodules (mGGO)proportion and pleural sag,lesion shape,grave leaves,burr,cavitation and the boundary conditions were compared. According to the relationship of the lesions and the surrounding blood vessels,3 types were classified,and the relationship of fGGO and blood vessel were analyzed.Results The minimal lesion was 0.41 cm of 95 cases and the maximum was 0.99 cm.There was statistically signifi-cant difference in the lesion size,solid component sizes,mGGO and lobulation occupied the percentage of the group before infiltrating and the adenocarcinoma group (P <0.05),and there was no statistically significant difference in pleural indentation,lesion shape,burr,vacuoles and boundary conditions (P >0.05).The difference was statistically significant in the leaflet occupied the percentage of the benign group com-pared with the adenocarcinoma group,and the differences of the remaining features were not statistically significant compared with the adeno-carcinoma group(P >0.05).According to the relstionship between fGGO and the vessels,patients in the benign group were type Ⅰ or typeⅡ,type Ⅲ was found in 10 cases of the group before infiltrating (25.6%),and type Ⅲ in 17 cases of the adenocarcinoma group (39.5%), the proportion of type Ⅲ of the group before infiltrating and the adenocarcinoma group was higher than that of the benign group (P <0.05). Conclusion The qualitative diagnosis of pulmonary fGGO is difficult,and the relationship between the morphology of the lesions under the MSCT and the surrounding vessels have some value for the diagnosis of the lesions.

Patent documentation is a kind of high-value scientific literature, which has caught the attention of more and more scholars. In this paper, the World Traditional Medicine Patent Database (WTMPD) was used to retrieve patents of the traditional medicines used in the treatment and prevention of influenza worldwide in the past 30 years. A total of 2 423 patents were further screened by a series of processes. Finally, multi-angle analysis was carried on the dataset to form a patent analysis report on traditional anti-flu drugs. From the analysis, we found that China had a rapid increase in the number of patent applications, which was in the leading role in the world, though the number of PCT applicant from China is relatively low. A large amount of applicants from the USA, Japan, and Korea have entered into China. Pharmaceutical company is the core group of patent applicant, who had applied a lot of quality patent about their products to protect their commercial interests. Honeysuckle, licorice, isatis root, forsythia and skullcap are five kinds of herbs, which have been most frequently used in anti-influenza patents.

Objective To study the effect of the extract of Chrysanthemum Indicum(CI)on the expression of tumor necro-sis factor-α (TNF-α) and neutrophil function in chronic bronchitis (CB)rats and to explore the therapeutic mechanism for chronic bronchitis. Methods The extract of CI was prepared. Wistar rats were randomly divided into blank control group, model group, Chuanxiling group, and low-, middle-and high-dose CI extract groups. Rat model of CB was established by intratracheal injection with low-dose lipopolysaccharide. After drug intervention, the expression of TNF-α in rat serum and bronchoalveolar lavage fluid was detected by ELISA method. Phagocytic function of the neu-trophil and respiratory burst of the rats were measured by flow cytometry (FCM). Results Compared with the blank con-trol group, the phagocytic function of the neutrophil, respiratory burst of the rats, and the expression of TNF-α in rat serum and bronchoalveolar lavage fluid of the model group were increased significantly. CI extract significantly decreased the abnormal rising of the above indexes. Conclusion Down-Regulation of TNF-α expression, and decrease of the neutrophil phagocytic function and rat respiratory burst may be one of the therapeutic mechanisms of Chrysanthemum In-dicum extract for the treatment of CB.

Ketotifen, a benzocycloheptathiophene, has an orally effective antiallergic as well as antihistaminic properties. In pervious studies, Ketotifen has shown encouraging results on patient with allergic rhinitis, either perennial or seasonal. 39 patients with allergic rhinitis had been treated with Ketotifen 1 mg twice daily for 8 weeks. And we obtained following results. 1) The efficacy rate in sneezing attack was 73.5%, in nasal discharge 71%, in nasal obstruction 58%. 2) Some improvements in at least one of three-major symptoms were noted within 1 week in 30.7%, within 2 weeks in 55.8%, within 3 weeks in 66.7%, within 8 weeks in 87.2%. 3) Physical findings such as colour, swelling of turbinate, character of rhinorrhea were not improved significantly. 4) Side effect was observed only in one patient with abdominal pain and diarrhea, which was subsided after interruption of administration. These results suggested that Ketotifen was effective in treatment of allergic rhinitis.

Objective To analyze the clinical characteristics of pneumomediastinum in patients with dermatomyositis and polymyositis for demonstrating its pathogenesis and for predicting its prognosis. Methods The clinical records of 96 patients with PM/DM were reviewed, focusing on for perdicting its pneumomediastinum. Five patients with pneumomediastinum are described in detail. Case reports of pneumomediastinum in PM/DM in English publications are reviewed. Results Five DM cases complicated by pneumomediastinum all had lung infections. Twenty-nine cases (including our five cases) of DM/PM with pneumomediastinum have taken methylprednisolone, four cases alive, and six died. Nine cases have taken CsA,seven cases alive and two died. Conclusion The infections was strongly suspected as being responsible for the pneumomediastinum. Methylprednisolone has poor effect. CsA can be an effective therapeutic agent in PM/DM.

The limitation so direct or indirect laryngoscopy and laryngogram in detemining the exact site and anatomiclocation of laryngeal carcinoma were well documented by many authors. As compared with laryngoscopy and laryngogram, CT study for laryngeal cancer is more exact and accurate method demonstrating anatomic sites of involvement, invasion into deep soft tissue spaces of endolarynx, destruction of laryngeal cartilages and cervical metastasis. Fourteen laryngeal cancer patients proven by laryngoscopic biopsy were further examined by computed tomography for staging. The authors compared laryngoscopic findings with those of computed tomography, and their clinical, surgical and computed tomographic findings were analysed. The results were as follows; 1. All patients were proved as squamous cell carcinoma. They were 12 males and 2 females aged over 50 yrs. 2. Common clinical symptoms were hoarseness, dysphagia and swallowing difficulty. The pirmary anatomic sites determined by CT were 8 transglottic, 2 glottic, 2 supraglottic and 1 pyriform sinus respectively. They were 2 T1. 7 T2, 1 T3, 3 T4 by TNM systems, respectivly. (One case was difficult to evaluate exactly). 3. Invasion into deep soft tissue spaces of endolarynx, cartilage destruction, and neck metastasis were relatively predominant in transglottic caracinomas. 4.CT was superior in evaluating tumor invasion, especially into deep soft tissue spaces of endolarynx, laryngeal cartilages and metastasis ot soft tissue and lymph nodes of neck. However CT had some limitation in determining primary site of laryngeal cancer.
