Objective To compare and analyze the application value of domestic Octoparms and imported Celect inferior vena cava filter(IVCF)in the interventional treatment of venous thromboembolism(VTE).Methods Forty patients with VTE were randomly divided into Octoparms group(experimental group)and Celect group(control group)according to the double-blinded method of the central random system.All the patients underwent filter placement,catheter-directed thrombolysis and filter retrieval.The primary end point was the success of filter placement and retrieval,and the secondary end point included indwelling complications such as the occurrence of pulmonary embolism(PE)and filter tilt and migration.Results Forty patients were enrolled in this study,22 patients and 18 patients were divided into the experimental group and the control group,respectively.Among them,11 cases were identified with right lower extremity deep vein thrombosis,29 cases with left lower extremity deep vein thrombosis,17 cases with PE,and 6 cases with inferior vena cava thrombosis.The success rate of IVCF placement was 100%in all participants.Immediately after filter place-ment,the angle of filter tilt was(3.8±2.3)° in the experimental group and(4.9±2.8)° in the control group(t=1.44,P=0.16).Filter retrieval was successful in 21 cases(21/22,95.5%)of the experimental group and 17 cases(17/18,95.5%)of the control group.There was no significant difference between the two groups(t=0.14,P=0.89).The mean indwelling time of filter was(8.0±2.1)days in the experimental group and(9.7±3.1)days in the control group(t=0.73,P=0.47).The angle of filter tilt was(5.3±3.4)° in the experimental group and(5.7±7.7)° in the control group(t=0.19,P=0.85).There was no significant difference for filter placement and retrieval between the two groups(t=0.48 and 2.00,P=0.06 and 0.64,respectively).There were no complications of filter migration,strut penetration or new PE in both groups.Conclusion The application value of domestic Octoparms and impor-ted Celect IVCF is similar in interventional treatment of VTE.

The combination of sourness,bitterness,sweetness,pungency,and saltness results in different effects.Through the analysis of the theory of combining five flavours in Fu Qingzhu's Obstetrics and Gynecology,this article explores its application in formulation ideas and the characteristics of Chinese medication,summarized as"primarily sweet,with all four flavors harmonized".FU Qingzhu emphasizes the central role of sweet-flavour medicine in facilitating conception,while incorporating the other four flavours in synergy.For instance,sweet and pungent flavours can boost yang energy,eliminating chilliness and warming the uterus;sour and sweet flavours can nourish yin essence and protect the uterus;bitter and sweet flavours can tonify yin,supporting the kidneys and moistening the uterus;and pungent and salty flavours can eliminate stasis,regenerate blood,and enhance uterine functions.By flexibly utilizing the flavours and meridian affinity of traditional Chinese medicine,along with the theory of combining five flavours,it is possible to enhance drug compatibility,deepen the theoretical connotation of Chinese formulas,and regulate the uterus from both yin and yang aspects to facilitate conception.FU Qingzhu's integration of multiple Chinese formulas into a single formula allows for comprehensive treatment.Clear differentiation of dosages within the formula highlights the primary and secondary relationships of traditional Chinese medicines.Additionally,the utilization of pharmaceutical processing techniques optimizes efficacy and regulates meridians and collaterals.This article explores FU Qingzhu's application of the"pure and harmonious traditional Chinese medicines"theory.His prescription thinking enables the attainment of multi-level therapeutic effects,which greatly benefits the optimization of traditional Chinese medicine fertility assistance programs and increases pregnancy rates among infertility patients.

Objective: To observe the clinical efficacy of Tuina (Chinese therapeutic massage) plus oxiracetam in treating mild vascular dementia (VD) and seek its underlying mechanism. Methods: Ninety-six patients with mild VD were randomized into an observation group and a control group, with 47 cases in the observation group and 49 cases in the control group. The control group received oral oxiracetam capsules for treatment, and the observation group was given additional Tuina treatment. Before and after treatment, the mini-mental state examination (MMSE) was adopted to assess the patient's cognitive function; the activities of daily living (ADL) scale was used to evaluate their ability to conduct daily activities; changes in the serum inflammatory factors and oxidative stress indicators were also detected. Results: After treatment, the serum content of malondialdehyde (MDA) decreased in both groups (P<0.05) and was lower in the observation group than in the control group (P<0.05); the serum contents of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) increased in both groups (P<0.05) and were higher in the observation group than in the control group (P<0.05); the serum contents of interleukin (IL)-1, tumor necrosis factor (TNF)-α, IL-6, and IL-8 declined in both groups (P<0.05) and were lower in the observation group than in the control group (P<0.05). After the intervention, the levels of systolic velocity (Vs) and mean velocity (Vm) of the middle cerebral artery elevated, and the pulsatility index (PI) dropped in patients in the two groups, showing significant intra-group differences (P<0.05); the levels of Vs and Vm in the observation group were higher than those in the control group, and the PI was lower in the observation group than in the control group, showing significant between-group differences (P<0.05). The MMSE and ADL scores increased in both groups after the intervention (P<0.05) and were higher in the observation group than in the control group (P<0.05). Conclusion: In the treatment of mild VD, Tuina plus oxiracetam can improve the cerebral blood supply, ADL, and cognitive function; the mechanism may be associated with the reduction of oxidative stress damages and inflammatory reactions.

Objective:To understand the current situation of knowledge, attitude and practice in the prevention and control of catheter-associated urinary tract infections (CAUTI) among community nurses in Pudong New Area in Shanghai and analyze influencing factors, so as to provide a basis for better community-based CAUTI prevention and control.Methods:Using the stratified random sampling method, a total of 286 community nurses from 4 areas in Pudong New Area in Shanghai were selected as the research objects from April to June 2021. The community nurses were surveyed by general information questionnaire, training situation questionnaire and CAUTI Prevention Knowledge, Attitude and Practice Scale. Univariate analysis and multiple linear regression were used to analyze the current situation and influencing factors of CAUTI prevention and control knowledge, attitude and practice among community nurses. Pearson correlation analysis was used to explore the correlations between knowledge, attitude and practice of CAUTI prevention and control among community nurses.Results:A total of 286 questionnaires were sent out and 283 valid questionnaires were recovered, with the effective recovery rate of 98.95%. Only 52.30% (148/283) community nurses had participated in CAUTI related training. The scores of CAUTI prevention and control knowledge, attitude and practice of community nurses were (85.04±5.31) , (23.28±2.73) and (21.39±2.07) , respectively. Univariate analysis showed that there were statistically significant differences in CAUTI prevention and control knowledge, attitude and practice scores among community nurses with different working years, professional titles, age, whether or not to train, training forms and training times ( P<0.01) . Multiple linear regression analysis showed that professional title and training frequency were the influencing factors of CAUTI prevention and control knowledge and practice of community nurses ( P<0.05) . Pearson correlation analysis showed that there were positive correlations between CAUTI prevention and control knowledge and attitude ( r=0.555, P<0.01) , knowledge and practice ( r=0.501, P<0.01) and attitude and practice ( r=0.417, P<0.01) . Conclusions:The level of CAUTI prevention and control knowledge, attitude and practice of community nurses in Pudong New Area in Shanghai needs to be improved and CAUTI-related training needs to be strengthened urgently. Medical institutions should actively carry out targeted CAUTI prevention and control knowledge training and assessment, improve CAUTI prevention and control knowledge reserves of community nurses, update prevention and control concepts, enhance community nurses' initiative and confidence in prevention and control, correctly implement various prevention and control measures and actively give play to the role of community nurses in the prevention and control of CAUTI.

Objective: To understand the consistency of ALK Ventana-D5F3 immunohistochemistry (IHC) interpretation in Chinese lung adenocarcinoma among histopathologists from different hospitals, and to recommend solution for the problems found during the interpretation of ALK IHC in real world, with the aim of the precise selection of patients who can benefit from ALK targeted therapy. Methods: This was a multicenter and retrospective study. A total of 109 lung adenocarcinoma cases with ALK Ventana-D5F3 IHC staining were collected from 31 lung cancer centers in RATICAL research group from January to June in 2018. All cases were scanned into digital imaging with Ventana iSCANcoreo Digital Slide Scanning System and scored by 31 histopathologists from different centers according to ALK binary (positive or negative) interpretation based on its manufacturer′s protocol. The cases with high inconsistency rate were further analyzed using FISH/RT-PCR/NGS. Results: There were 49 ALK positive cases and 60 ALK negative cases, confirmed by re-evaluation by the specialist panel. Two cases (No. 2302 and No.2701) scored as positive by local hospitals were rescored as negative, and were confirmed to be negative by RT-PCR/FISH/NGS. The false interpretation rate of these two cases was 58.1% (18/31) and 48.4% (15/31), respectively. Six out of 31 (19.4%) pathologists got 100% accuracy. The minimum consistency between every two pathologists was 75.8%.At least one pathologist gave negative judgement (false negative) or positive judgement (false positive) in the 49 positive or 60 negative cases, accounted for 26.5% (13/49), 41.7% (25/60), respectively, with at least one uncertainty interpretation accounted for 31.2% (34/109). Conclusion There are certain heterogeneities and misclassifications in the real world interpretation of ALK-D5F3 IHC test, which need to be guided by the oncoming expert consensus based on the real world data.

Objective To evaluate the clinical effect of reduced glutathione in protecting the liver function for patients with hepatocellular carcinoma (HCC) after receiving international therapy.Methods The clinical data of 110 HCC patients,who were admitted to authors' hospital during the period from January 2010 to June 2013,were retrospectively analyzed.According to the random number table method the patients were divided into the control group (n=50) and the treatment group (n=60),and transcatheter arterial chemoembolzation (TACE) and transcatheter arterial infusion (TAI) were carried out in all patients.After the treatment,intravenous infusion of 2.0 g vitamin C,0.2 g vitamin B6,2.0 g inosine,and 250 ml branched chain amino acid was employed per day for one week for the patients of both groups,and additional intravenous dripping of 1.8 g reduced glutathione (added in 250 ml of 5％ glucose solution) was adopted for the patients of the treatment group.Various liver function indexes were tested before and one week after the treatment,the results were compared between the two groups.Results Before the treatment,no obvious differences in the hepatic functions and in the clinical condition existed between the two groups.One week after the treatment,in both groups the aminotransferase (ALT and AST) and total bilirubin (TBIL) were significantly increased when compared with the preoperative data (P＜0.05),while the serum pre-albumin (PA) was remarkably decreased when compared with the preoperative data (P＜0.05);these changes of various indexes in the treatment group were apparently better than those in the control group (P＜0.05).Conclusion The use of reduced glutathione can effectively relieve the liver function damage caused by interventional therapy in HCC patients,therefore,reduced glutathione has a very good clinical application value.

After confirmation of the diagnosis, endovascular treatment was performed. Then the occluded blood vessels resumed blood stream, urine output increased, and abdominal distension was significant relieved. Conclusions In young children, BCS is rare, the condition is complex, and endovascular therapy is effective.

BACKGROUND:Dorsal digital block refers to the commonly used anesthesia for adults in smal or moderate hand injury surgeries, but in recent years, modified transthecal digital block technique is gradualy respected, which is favored with a rapid and good effect and fewer complications.
OBJECTIVE:To evaluate the clinical anesthetic outcomes of modified transthecal digital block and traditional dorsal digital block technique for the treatment of hand injury of adults in emergency by a prospective randomized controled study.
METHODS:Totaly 60 adult patients with hand injury were enroled and divided into two groups of modified transthecal digital block and traditional dorsal digital block randomly. Blocks were performed by one single surgeon. The operation time, local anesthetic dose, onset time of anesthesia, duration of anesthesia, success rate of anesthesia, visual analogue scale scores and complications were recorded.
RESULTS AND CONCLUSION:The anesthesia effects in the two groups were acceptable. There was no significant difference in the onset time of anesthesia, duration of anesthesia, success rate of anesthesia and complications between the two groups (P > 0.05). The operation time of anesthesia, local anesthetic dose, and visual analogue scale scores were significantly different between the two groups (P< 0.05). Modified transthecal digital block is more convenient and has less pain than the traditional root digital block, which is a safe and reliable anesthetic technique.

Objective To explore the therapeutic efficacy of endovascular embolization for the treatment of tiny intracranial aneurysms (≤3.0 mm) and to discuss its technical skill. Methods During the period from Dec. 2010 to July 2013, a total of 12 patients with tiny intracranial aneurysms (≤3.0 mm) were admitted to authors’ hospital to receive endovascular embolization therapy. Of the 12 patients, narrow-necked aneurysm (neck-to-body ratio ≤0.5) was seen in 7 and embolization with coils only was carried out, while wide-necked aneurysm (neck-to-body ratio > 0.5) was seen in 5 and stent-assisted coils embolization was adopted. Based on Raymond grading standard, the immediate therapeutic results were evaluated, and the procedure-related complications were recorded. Thirty days after the treatment , GOS grade was used to assess the results. Follow-up evaluation with angiography or through call was conducted. Results Successful embolization of the aneurysm was obtained in all the 12 aneurysms , with a success rate of 100%. Angiography performed immediately after the treatment showed that complete embolization was achieved in 8 aneurysms (66.7%) and residual aneurysm cavity was seen in 4 aneurysms (33.3%). GOS grading indicated that 12 cases belonged to grade V. The 12 patients were followed up for 1 - 12 months through telephone , and no re-bleeding occurred. Conclusion For the treatment of tiny intracranial aneurysms (≤ 3.0 mm), endovascular embolization is feasible although its safety and efficacy need to be further observed.
