Objective To observe the clinical effect of Blade needle closed release and massage for the patients with cervical heart syndrome. Methods A total of 60 patientswith cervical-heart syndrome were randomly divided into the control group and the treatment groups, 30 patients in each group. Both groups were treated with rehabilitation exercises, and the treatment group were added with Blade needle closed release and massage, while the control group were added with traction. The treatments were operated once to 3 times based on the patients' condition with an interval of seven days. The symptoms, signs and effective rates were observed and compared. Results After treatment, the neck and shoulder pain (0.7 ± 0.6 vs. 0.9 ± 0.7, t=2.904), precordialgia (0.5 ± 0.5 vs. 1.0 ± 0.7, t=4.210), chest tightness (0.5 ± 0.6 vs. 0.8 ± 0.7, t=2.093), cardiopalmus (0.7 ± 0.5 vs. 1.0 ± 0.8, t=3.915), spontaneous (0.7 ± 0.5 vs. 0.8 ± 0.9, t=2.837), vertigo (1.0 ± 0.6 vs. 1.6 ± 0.8, t=2.760) scores in the treatment group were significantly lower than those in the control group (P<0.05 or P<0.01). The total effective rate of the treatment group was 93.89% (28/30), and the Control group was 66.67%(20/30). There are significantly different(χ2=4.547, P<0.05). Conclusions The method of Blade needle closed release and traction could improve the symptom of the shoulder neck and heart area of the cervical-heart syndrome.

Objective To observe and evaluate the long-term efficacy and safety of PPH plus partial internal anal sphincterotomy for severe mixed hemorrhoids .Methods Choose 103 patients who were diagnosed with severe mixed hemorrhoids from May 2008 to May 2010 .Then divided these patients into the experimental group of 52 patients and the control group of 51 patients ,randomly . The patients of experimental group were treated by PPH plus partial internal anal sphincterotomy ,and the patients of control group were treated by the simple PPH operation .Have a postoperative followed up for 24 months to check and compare the long-term ef-ficacy and safety of two groups .Results The incidence of prolapse recurrence ,anus pain and hemafecia in experimental group were significantly lower than that in control group(P<0 .05) ,there was no significance of the anal incontinence and anal stenosis in two groups(P>0 .05) .Conclusion The therapy of the PPH plus partial internal anal sphincterotomy for severe mixed hemorrhoids can significantly reduce the recurrence ,and improve the long-time efficacy ,but not to increase additional risk .

Objective To investigate the construction and value of radiation pneumonitis(RP)predic-tive model based on machine learning algorithm.Methods A retrospective analysis was conducted on the clin-ical data in 77 patients with breast cancer receiving radiotherapy and regular follow-up in this hospital from August 2019 to September 2022.The affected side lung was delineated on the localization CT as the area of in-terest and the radiomics features were extracted,meanwhile the affected side lung dosimetric parameters were extracted.After feature screening,the patients were divided into the training set and testing set by a 7∶3 rati-o.The features of positioning CT radiomics were extracted and combined with the dosimetry parameters of the affected side lung,and the model was established by using stochastic gradient descent(SGD)algorithm.The performance of the model was validated by using the area under the receiver operating characteristic(ROC)curve(AUC)and decision curve analysis(DCA).Results Among 77 patients,24 cases developed RP after ra-diotherapy end with an incidence rate of 31.17％.Compared with the patients without RP occurrence,V5,V10,V15,V20,V25,V30 and mean lung dose(MLD)in the patients with RP occurrence were higher,and the differ-ence was statistically significant(P＜0.05).In the training set,36 cases did not develop RP.17 cases devel-oped RP,in the testing set,17 cases did not develop RP and 7 cases developed RP.The affected side lung dosi-metric parameters had no statistical difference between the training set and testing set with and without RP occurrence(P＞0.05).After characteristics screening,the 8 optimal characteristics combinations were finally obtained.The average AUC of SGD model in 50％off cross-validation of the training set was 0.900 and AUC in the test set was 0.882.Conclusion The positioning CT radiomics features combined with dosimetry param-eters of the affected side lung has the good predictive value for RP after breast cancer radiotherapy.
