ObjectiveTo observe the effectiveness of collagen sponge for reducing volume of drainage after surgery for lumbar spinal stenosis. MethodsOne hundred and eighty-six patients who suffered from lumbar spinal stenosis were divided into two groups by random digits table method. The test group(96 cases) used collagen sponge to cover dura mater before placing drainage tube,the control group (90 cases) was treated without collagen sponge. The volume of drainage at 1,12,24 h after surgery were observed, the blood routine test was carried out at before and 48 h after surgery and the volume and ratio of blood transfusion after surgery was also measured and compared between the two groups. ResultsThe volume of drainage were significantly decreased in the test group compared with the control group at 1,12,24h after surgery [( 106.11 ± 20.02 ) ml vs. ( 127.02 ± 25.09) ml, (236.12 ± 34.06) ml vs. (327.31 ± 51.21 )ml, (355.16 ± 49.03 ) ml vs.( 506.36 ± 85.29 ) ml](P ＜ 0.05 ). The volume and the ratio of blood transfusion in the test group were ( 176.27 ± 21.37) ml and 10.42％(10/96) ,which were greatly lower than those in the control group[(445.94 ±24.56) ml and 32.22％ (29/90)](P ＜0.05). The number of RBC and the concentration of Hb were (2.96 ± 0.45 ) × 1012/L and ( 106.75 ± 7.30) g/L, differently in the test group at 48 h after surgery,which were increased significantly compared with the control group[(2.35 + 0.57) × 1012/Land (90.45 ± 5.10) g/L](P ＜ 0.05 ). ConclusionsCollagen sponge provides rapid ,effective and durable hemostasis and decreases the leak of cerebrospinal fluid after surgery for lumbar spinal stenosis. It can be used as an effective and economic method to reduce the volume of drainage after surgery.

Objective To evaluate the curative effect,safety,and medium-term effect of intracranial artery stenosis stent (ICASS) for the treatment of the symptomatic intracranial artery stenosis.Methods ICASS was performed in 21 cases with the symptomatic intracranial artery stenosis.The stenting success rate,the improvement rate of stenosis post-stenting and the incidence of complications were observed.The change of the scores of the Modified Rankin Scale (MRS)and National Institutes of Health Stroke Scale (NIHSS)between pre-and post-stenting (1 month,3 months,6 months,12 months and 2 years)and the occurrence of ischemic cerebrovascular events after stenting were compared and analyzed respectively.Results Except one case failed because of intracranial hemorrhage during the operation,other 20 patients were treated with endovascular stent plasty successfully,the total technical achievement ratio was 95.2%.The aver-age stenosis ratio decreased from (73.4±7.9)% to (13.7±9.2)%.The complications incidence was 4.8% within the peroperative. 9 patients were reviewed with DSA in 6 months,the average ratio of stenosis was (29.5 ±12.2)%,no patient was found with the restenosis.Compared with pre-stenting,the score of MRS and NIHSS at the follow-up duration of 3 months,6 months,12 months and 2 years post-stenting of patients were significant improved (all P < 0.05 ).During the follow-up period,2 patients were found with new transient ischemia attack (TIA),1 patient had non-targeted vascular CI without other target vascular therapy-related com-plications.Univariate analysis indicated that patients with elderly (≥ 75 years old),or hypertension,or diabetes,or dyslipidemia,or in the set of events to endovascular treatment for longer than 1 month,or with more than two independent risk factors for patients with underlying diseases treatment,or without systemic therapy,whom would be much more easily to reoccur the cerebrovascular events in post-operation(all P <0.05 ).Conclusion ICASS should be an effective and safe therapeutic method to the symptomatic intracra-nial arterial stenosis.The medium-term efficacy is significant.Serious complications might still be emerge with endovascular stent plasty,so close attention must be paid with.

Objective To analyze the factors related to the occurrence of complications in performing CT-guided percutaneous lung biopsy with 18 G-Bard Magnum needle. Methods CT-guided percutaneous lung biopsy with 18 G-Bard Magnum needle was carried out in a total of 58 patients. The postoperative complications were recorded, and the related factors causing complication were analyzed. Results Successful puncturing was achieved in all patients with a technical success rate of 100%. Postoperative complications included pulmonary hemorrhage (n=11,19.0%), a little amount of bleeding in needle tract (n=7,12.1%), hemoptysis (n=3,5.2%), hemothorax (n=1,1.7%), and pneumothorax (n=10,17.2%). Chi-square test showed that the occurrence of pulmonary hemorrhage bore a close relationship to the lesion’s diameter, the distance between the lesion and the chest wall, the lesion’s location and times of puncturing (P<0.05). The occurrence of pneumothorax was closely correlated with the age, the distance between the lesion and the chest wall, the presence of perifocal emphysema, the lesion’s location and times of puncturing (P<0.05). Univariate analysis indicated that the postoperative complications were liable to occur in the patients whose imaging examination showed perifocal emphysema and lung hilar lesion, and who had more than two independent risk factors (P<0.05). Conclusion CT-guided percutaneous lung biopsy with 18 G-Bard Magnum needle is an accurate and safe technique with relatively higher positive diagnosis rate, but this technique should be carefully used in patients who has perifocal emphysema, or lung hilar lesion, or more than two independent risk factors.(J Intervent Radiol, 2015, 24:792-796)

Objective To explore the effects of preoperative fun game on the physiological indicators and the degree of cooperation in the treatment of Bianchi in cryptorchidism children. Methods From July 2013 to June 2016, totally 136 cases of cryptorchidism children who were treated with Bianchi method in Affiliated Hospital of Ji'ning Medical University were selected as research objects. The patients were numbered according to the order of admission, and randomly divided into observation group and control group with 68 cases in each by random table method. The control group was given routine psychological education, while the observation group was treated with interest game before operation. The mean arterial pressure (MAP), heart rate (HR), modified Yale preoperative anxiety scale (mYPSA), and the degree of anesthesia coordination were compared between the two groups when entering operation room and during anesthesia induction. Results There was no statistical difference in MAP and HR of the children between the two groups when entering operation room (P>0.05), whereas the MAP and HR of the observation group children were significantly lower than those of the control group during anesthesia induction, and the differences were statistically significant (t=3.012, 2.498;P<0.05). There was no significant difference in anxiety scores between the two groups when entering operation room (P> 0.05). However, during the anesthesia induction the anxiety score of the observation group was significantly lower than that of the control group, and the difference was statistically significant (t=4.021, P<0.01). The score of cooperation level in observation group was significantly lower than that in control group, with statistical difference (Z=3.578,P< 0.01). Conclusions The application of preoperative fun game in the Bianchi treatment of cryptorchidism children can improve patients' cooperation degree and reduce preoperative anxiety.

Objective:To explore the association between internet use and healthy lifestyles in urban adults.Methods:From May to August, 2022, a face-to-face questionnaire survey was conducted in residents aged 18-64 years selected in the urban area of Hangzhou by integrated cluster stratified random sampling and Kish grid method. The information about internet use included the internet use time in the past 7 days and 12 kinds of internet use contents. Using factor analysis and K-means clustering, three types of internet use were summarized, i.e. general type, video game type and working/learning type. Healthy lifestyles were defined as active physical activity, healthy diet habit, non-smoking, non-drinking, healthy weight, and healthy waist circumference. The correlations between internet use and healthy lifestyles were evaluated by using binary logistic regression and multinomial logistic regression analyses.Results:A total of 1 624 participants were included. After adjusting for potential confounding factors, the longer internet use time group (≥8.5 h/d) was less likely to have healthy weight ( OR=0.59, 95% CI:0.41-0.85) and 5-6 healthy lifestyles ( OR=0.55, 95% CI: 0.32-0.96) compared with those with shorter internet use time group (<2.5 h/d). For different types of internet use, it was found that compared with working/learning type group, the general type group was less likely to have healthy diet habits ( OR=0.63, 95% CI: 0.46-0.86), non-drinking ( OR=0.68, 95% CI: 0.47-0.99), healthy waist circumference ( OR=0.59, 95% CI: 0.42-0.84) and 5-6 healthy lifestyles ( OR=0.40, 95% CI: 0.23-0.69), the video game type group was less likely to have active physical activity ( OR=0.73, 95% CI: 0.55-0.97) and healthy diet habits ( OR=0.79, 95% CI: 0.62-0.99). Conclusion:Too long internet use (≥8.5 h/d), general type and video game type of internet use were associated with unhealthy lifestyles.

OBJECTIVE To explore the influence of Zingiber officinale and processed Z. officinale on pharmacodynamic indexes and intestinal flora on gastric ulcer rats with spleen -stomach deficiency and cold type before and after processing with sand . METHODS The SD rats were randomly divided into normal group ，model group ，positive control group （Compound tianqi weitong capsule 0.45 g/kg），Z. officinale high-dose（15.0 g/kg）and low -dose（7.5 g/kg）groups，processed Z. officinale high- dose（15.0 g/kg）and low -dose（7.5 g/kg）groups，with 10 rats in each group . The rat model of gastric ulcer with spleen -stomach deficiency and cold type was established by intragastric administration of vinegar （day 1-10）and absolute ethanol （day 11）. Administration groups were given relevant liquid intragastrically ，and normal group and model group were given water intragastrically（day 5-10）. One hour after intragastric administration of absolute ethanol ，blood was taken from the femoral artery of rats ，the serum contents of motilin （MTL），gastrin（GAS），epidermal growth factor （EGF）as well as 4 items of blood coagulation [activated partial thromboplastin time （APTT），prothrombin time （PT），thrombin time （TT），fibrinogen（FIB）] were detect. The ulcer index and inhibition rate of ulcer in gastric tissue were calculated . The pathological changes of gastric tissue were observed，and the number and area of erosions were recorded . The diversity of gut microbiota in fecal samples of rats was detected . RESULTS Compared with model group ，the contents of MTL （except for processed Z. officinale low-dose group ），GAS（except for processed Z. officinale low-dose group ），EGF（except forofficinale groups） and FIB （except for Z. officinale groups），inhibitory rate of ulcer （only positive control group ）were all increased significantly （P＜0.05）. APTT（except for Z. officinale groups），PT（only processed Z. officinale high- dose group ），TT（except for Z. officinale groups），ulcer index （except for Z. officinale groups），the number （except for Z. officinale groups）and area of erosions （except for Z. officinale groups）were shortened and decreased significantly （P＜0.05）； improvement effects of processed Z. officinale were better than those of the same dose of Z. officinale on EGF ，4 items of blood coagulation（except for PT ，TT，FIB of processed Z. officinale low-dose group ），ulcer index （except for processed Z. officinale low-dose group ）and inhibitory rate of ulcer （P＜0.05）. Compared with model group ，α diversity indexes as ACE ，Shannon and Simpson of intestinal microorganisms in rats were increased significantly in processed Z. officinale group；the relative abundance of Proteobacteria was decreased significantly in processed Z. officinale group，while that of Bacteroidetes was increased significantly （P＜0.05）； the relative abundance of Limosilactobacillus was decreased significantly in Z. officinale group （P＜0.05）. CONCLUSIONS Z. officinale and processed Z. officinale can improve the symptoms of spleen -stomach deficiency and cold ，and enhance gastrointestinal function by increasing the content of GAS and MTL . Processed Z. officinale can significantly inhibit gastric ulcer of spleen -stomach deficiency and cold type ，which is related to the promotion of mucosal protection and repair ，improvement of coagulation functionand adjustment of gut microbiotadisorder .

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.
