ObjectiveTo explore whether the posture changing can ameliorate the dysuria for patients with femoral artery puncture and catheterization, and observe the influence of posture changing on blooding in the point of puncture. Methods Changing patients′ posture under the order of nurses, and then observed the amelioration condition of dysuria. Results After using intervention method, the rate of urinary stasis decreased from 31.67% to 4.17%, the rate of using urethral catheterization also decreased from 8.33% to 1.67%. Conclusion Posture changing was an effective method to ameliorate the dysuria for patients with femoral artery puncture and catheterization.

Objective To evaluate the feasibility,safety and clinical value of CT-guided localization with a Hook-wire system for nodular pulmonary lesions before video-assisted thoracoscopic resection (VATS). Methods The records of all patients undergoing VATS resection for solitary pulmonary nodules preoperatively localized by CT-guided a Hook-wire system were assessed with respect to failure to localize the lesion by the Hook-wire system, conversion thoracotomy rate, duration of operation, postoperative complications, and histology of nodular pulmonary lesions. Results Sixty-eight patients with seventy four nodules underwent VATS resections. Preoperative CT-guided Hook-wire localization succeeded in all patients ( 100. 0% ). Conversion thoracotomy was necessary in 2 patients. The average operative time was ( 15 ±6)min. Asymptomatic complication rate was 70.6% (48/68), asymptomatic pneumothorax rate, asymptomatic hemorrhage rate and simultaneous pneumothorax and bleeding rate were 45.6% (31/68),25.0% ( 17/68 ) and 4. 4% ( 3/68 ), respectively. The mean hospitalization was ( 15 ± 6 ) days.Histological assessment revealed primary lung cancer (NSCLC) in 30, metastasis in 18, and nonmalignant disease in 26 nodules. Conclusions Video-assisted thoracoscopic resection of nodular pulmonary lesions previously localized by a CT-guided Hook-wire system is related to a low conversion thoracotomy rate, short operation time, and high safety. It for differential diagnosis and treatment.

OBJECTIVE: To analyze the indications of the therapies for rheumatoid arthritis (RA) with neural network model analysis. METHODS: Three hundred and ninety-seven patients were included in the clinical trial from 9 clinical centers. They were randomly divided into Western medicine (WM) treated group, 194 cases; and traditional Chinese herbal medicine (CM) treated group, 203 cases. A complete physical examination and 18 common clinical manifestations were prepared before the randomization and after the treatment. The WM therapy included voltaren extended action tablet, methotrexate and sulfasalazine. The CM therapy included Glucosidorum Tripterygii Totorum Tablet and syndrome differentiation treatment. The American College of Rheumatology 20 (ACR20) was taken as efficacy evaluation. All data were analyzed on SAS 8.2 statistical package. The relationships between each variable and efficacy were analyzed, and the variables with P<0.2 were included for the data mining analysis with neural network model. All data were classified into training set (75%) and verification set (25%) for further verification on the data-mining model. RESULTS: Eighteen variables in CM and 24 variables in WM were included in the data-mining model. In CM, morning stiffness, swollen joint number, peripheral immunoglobulin M (IgM) level, tenderness joint number, tenderness, rheumatoid factor (RF), C-reactive protein (CRP) and joint pain were positively related to the efficacy, and disease duration and more urination at night negatively related to the efficacy. In WM, erythrocyte sedimentation rate (ESR), weak waist, white fur in tongue, joint pain, joint stiffness and swollen joint were positively related to the efficacy, and yellow fur in tongue, red tongue, white blood negatively related to the efficacy. In the analysis with the neural network model in the patients of verification set, the predictive response rates of 20% patients would be 100% and 90% in the treatment with CM and WM, respectively. CONCLUSION: Neural network model analysis, based on the full clinical trial data with collection of both traditional Chinese medicine and modern medicine diagnostic information, shows a good predictive role for the information in the efficacy in rheumatoid arthritis.

OBJECTIVE: To evaluate the correlations between clinical symptoms and treatment efficacy in patients with rheumatoid arthritis (RA). METHODS: Four hundred and thirteen patients were included in the clinical trial from 9 clinical centers. They were randomly divided into Western medicine-treated group with 204 cases and Chinese herbal drug-treated group with 209 cases. Eighteen clinical symptoms were evaluated before and after treatment. The Western medicine therapy included voltaren extended release tablets, methotrexate and sulfasalazine. The Chinese herbal drug therapy included glucosidorum Tripterygii totorum tablets and Yishen Juanbi Tablets combined with treatment based on syndrome differentiation. The American College of Rheumatology 20 (ACR20) was used as efficacy evaluation criteria. RESULTS: In the Chinese herbal drug-treated group, clinical symptoms such as arthralgia and tenderness of joints were positively correlated with the efficacy after 12-week treatment, while frequent urination at night was negatively correlated. In the same group, tenderness of joints and fever were positively correlated with the efficacy after 24-week treatment, while deep-colored and turbid urine was negatively correlated. In the Western medicine-treated group, tenderness of joints and thirst were positively correlated with the efficacy after 12-week treatment, while vertigo was negatively correlated. And in the same group, tenderness of joints was positively correlated with the efficacy after 24-week treatment, while heaviness of limbs was negatively correlated to the efficacy. The statistical results showed that the treatment efficacy was improved when the correlated symptoms were included in the indications. CONCLUSION: The treatment efficacy of RA is correlated with some symptoms, so further studies should proceed on these correlations in order to achieve better treatment outcome.
