OBJECTIVE: To investigate the relationship between serum matrix metalloproteinase-1(MMP-1) and matrix metalloproteinase-2(MMP-2) and the formation of deep venous thrombosis(LDVT) in lower extremity patients after surgery for lower extremity fracture, and to analyze the value of MMP-1 and MMP-2 in predicting the occurrence of LDVT after lower extremity fracture. METHODS: From June 2018 to December 2021, 352 patients who planned to receive surgical treatment of lower limb fracture in our hospital were selected as the research objects. Venous blood was collected at 1, 2 and 3 days after surgery, respectively, and serum MMP-1 and MMP-2 levels were detected. The incidence of LDVT during hospitalization was analyzed, and the risk factors of postoperative LDVT in patients with lower limb fracture surgery and the predictive value of MMP-1 and MMP-2 for LDVT were analyzed. RESULTS: LDVT occurred in 40 patients (LDVT group), the incidence of LDVT was 11.36%, and 312 patients did not occurred(no occurred group). The serum levels of MMP-1 and MMP-2 in LDVT group increased gradually after surgery; the serum levels of MMP-1 and MMP-2 in the no occurred group increased slightly after surgery at 2 days and then decreased at 3 days after surgery (P<0.01);the serum levels of MMP-1 and MMP-2 in LDVT group were higher than those in the no occurred group at 2 days and 3 days after surgery (P<0.05). Serum levels of MMP-1 and MMP-2 were positively correlated with serum levels of interleukin-6 (IL-6), IL-8 and tumor necrosis factor -α (TNF-α) in LDVT patients at 2 days and 3 days postoperatively (P<0.05). Operative time, MMP-1 and MMP-2 postoperative 3 days were related to the occurrence of LDVT after lower limb fracture (P<0.01). The area under the curve(AUC) predicted by MMP-1 and MMP-2 postoperative 3 days for LDVT after lower limb fracture was 0.738 and 0.744 respectively, and the AUC predicted by combined MMP-1 and MMP-2 was 0.910, which was higher than that predicted by single indicator(Z=2.819 and 2.025, P<0.05). CONCLUSION High levels of MMP-1 and MMP-2 after lower extremity fracture are closely related to the occurrence of LDVT, and 3 d mMP-1 and MMP-2 after surgery maybe used as evaluation indexes for LDVT risk prediction.

OBJECTIVE: To investigate the clinical effect of aconite-isolated moxibustion at Yongquan (KI 1) combined with rivaroxaban for lower extremity venous thrombosis after total knee arthroplasty and the influence on hypercoagulation. METHODS: Seventy-three patients of knee osteoarthritis with lower extremity venous thrombosis after total knee arthroplasty (KOA) were randomly divided into an observation group (37 cases, 2 cases dropped off) and a control group (36 cases, 1 case dropped off). The patients in the control group took orally rivaroxaban tablets, 10 mg a time, once a day. On the basis of the treatment as the control group, the aconite-isolated moxibustion was applied to Yongquan (KI 1) for the patients of the observation group, once daily and 3 moxa cones were used in each treatment. The duration of treatment was 14 days in both groups. Before treatment and 14 days into treatment, the ultrasonic B test was adopted to determine the conditions of lower extremity venous thrombosis in the two groups. Before treatment, 7 and 14 days into treatment, the coagulation indexes (platelet [PLT], prothrombin time [PT], activated partial prothrombin time [APTT], fibrinogen [Fib] and D-dimer[D-D]), the blood flow velocity of the deep femoral vein and the circumference of the affected side were compared between the two groups separately, and the clinical effect was evaluated. RESULTS: Fourteen days into treatment, the venous thrombosis of the lower extremity was relieved in both groups (P<0.05), and that of the observation group was better than the control group (P<0.05). Seven days into treatment, the blood flow velocity of the deep femoral vein was increased compared with that before treatment in the observation group (P<0.05), and the blood flow rate in the observation group was higher than that in the control group (P<0.05). Fourteen days into treatment, PT, APTT and the blood flow velocity of the deep femoral vein were increased in the two groups compared with those before treatment (P<0.05); and PLT, Fib, D-D and the circumference of the limb (knee joint, 10 cm above the patella and 10 cm below the patella) were all reduced in the two groups (P<0.05). Compared with the control group 14 days into treatment, the blood flow velocity of the deep femoral vein was higher (P<0.05), PLT, Fib, D-D and the circumference of the limb (knee joint, 10 cm above the patella and 10 cm below the patella) were all lower in the observation group (P<0.05). The total effective rate was 97.1% (34/35) in the observation group, higher than 85.7% (30/35) in the control group (P<0.05). CONCLUSION Aconite-isolated moxibustion at Yongquan (KI 1) combined with rivaroxaban can effectively treat lower extremity venous thrombosis after total knee arthroplasty, relieve hypercoagulation, accelerate the blood flow velocity and alleviate swelling of the lower extremity in the patients with knee osteoarthritis.

BACKGROUND: Lung cancer is the first leading cause of morbidity and mortality among the malignant tumors, which has become a hot issue in current research. Clinically, lung cancer is divided into small cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC) according to the pathological types. NSCLC includes adenocarcinoma, squamous cell carcinoma and other types of lung cancer, accounting for about 80% of all lung cancer. Venous thromboembolism (VTE) includes deep venous thrombosis (DVT) and pulmonary embolism (PE), which is a recognized complication in lung cancer patients with higher morbidity and mortality. The aim of this study is to determine the incidence of DVT and reveal the risk factors for DVT in the postoperative patients with lung cancer. METHODS: We collected 83 postoperative patients with lung cancer admitted to the Department of Lung Cancer Surgery, Tianjin Medical University General Hospital from December 2021 to December 2022. All these patients were examined by color Doppler ultrasound of lower extremity vein upon admission and after operation to analyze the incidence of DVT. In order to explore the possible risk factors for DVT in these patients, we further analyzed the correlations between DVT and their clinical features. At the same time, the changes of coagulation function and platelet were monitored to investigate the value of blood coagulation in the patients with DVT. RESULTS: DVT occurred in 25 patients after lung cancer operation, and the incidence rate of DVT was 30.1%. Further analysis found that the incidences of postoperative lower limb DVT were higher in lung cancer patients of stage III+IV or over 60 years of age (P=0.031, P=0.028). D-Dimer level in patients with thrombosis was significantly higher than that in non-thrombus patients on the 1st, the 3rd, and the 5th day after operation (P<0.05), and there was no significant difference in platelets and fibrinogen (FIB) (P>0.05). CONCLUSIONS The overall incidence of DVT in our center after lung cancer patients operation was 30.1%. Late-stage and older postpatients were more likely to develop DVT, and these patients with higher D-Dimer values should be considered the possibility of VTE events.

Objective: To investigate the effects of primary preventive treatment under endoscope for esophageal and gastric varices on bleeding rate and its relevant factors. Methods: 127 cases with liver cirrhosis accompanied with esophageal and gastric varices without bleeding history were included in the endoscopic and non-endoscopic treatment group, respectively. Informed consent was obtained from both groups. Gastric varices (Lgf) and esophageal varices (Leg) were diagnosed according to LDRf classification criteria, and the corresponding treatment scheme was selected according to the recommended principle of this method.The incidence rate of bleeding from ruptured esophageal varices were observed at 3, 6 months, and 1, and 2 years in the treated and the untreated group, and the patients with different Child-Pugh scores were followed-up for 2 years. Gender, age, etiology, varicose degree, Child-Pugh grade, platelet count, prothrombin activity, portal vein thrombosis, collateral circulation, portal vein width and other factors affecting the bleeding rate were assessed. Measurement data were described as mean ± standard deviation (x¯±s), and qualitative data of categorical variables were expressed as percentage (%), and χ² test was used. Results: 127 cases were followed up for 2 years. There were 55 cases in the endoscopic treatment group (18 cases underwent band ligation, 2 cases underwent band ligation combined with tissue adhesive embolization, 28 cases underwent sclerotherapy, and 7 cases underwent sclerotherapy combined with tissue adhesive embolization). Recurrent bleeding and hemorrhage was occurred in 5 (9.1%) and 28 cases (38.9%), respectively (P<0.05). In addition, there were 72 cases in the untreated group (P<0.05). Severe varicose veins proportions in treated and untreated group were 91.1% and 85.1%, respectively (P>0.05). There was no statistically significant difference in liver cirrhosis-related medication and β-blocker therapy between the treated and untreated group (P>0.05). There was no statistically significant difference in the bleeding rate between the different treated groups (P>0.05). The bleeding rates at 3, 6 months, 1, and 2 years in endoscopic treated and untreated group were 2.00% vs. 2.59% (P>0.05), 2.30% vs. 5.88% (P>0.05), 3.10% vs. 7.55% (P>0.05) and 4.00% vs. 21.62% (P<0.05), respectively. All patients with Child-Pugh grade A, B and C in the treated and the untreated group were followed-up for 2 years, and the bleeding rates were 1.8% vs. 8.1% (P<0.05), 1.1% vs. 9.4% (P<0.05) and 9.1% vs. 10.1% (P>0.05), respectively. There were statistically significant differences in the rupture and bleeding of esophageal and gastric varices, varices degree, Child-Pugh grade and presence or absence of thrombosis formation in portal vein (P<0.05); however, no statistically significant differences in gender, age, etiology, platelet count, prothrombin activity, collateral circulation and portal vein width (P>0.05). There was no intraoperative bleeding and postoperative related serious complications in the treated group. Conclusion: The risk of initial episodes of bleeding from esophageal and gastric varices is significantly correlated with the varices degree, Child-Pugh grade, and portal vein thrombosis. Primary preventive treatment under endoscope is safe and effective for reducing the long-term variceal bleeding risk from esophageal and gastric varices.

OBJECTIVE: To explore the effect of intermittent pneumatic compression(IPC) combined with 3M thermometer on the prevention of deep venous thrombosis(DVT) in patients with femoral intertrochanteric fracture. METHODS: From March 2016 to August 2019, 127 patients with femoral intertrochanteric fractures who underwent proximal femoral nail antirotation(PFNA) were retrospectively analyzed. They were divided into two groups according to different methods of thrombus prevention and treatment. Among them, 63 patients in group A did not use IPC and 3M thermometer;64 cases in group B were treated with IPC combined with 3M thermometer. Color Doppler ultrasound was used to dynamically monitor the DVT and changes of lower limbs during perioperative period. The venous thrombosis of lower limbs was monitored at 0, 24, 72 h and > 72 h after operation(recheck every 3 days until discharge). RESULTS: Occurrence of DVT of lower limbs after PFNA operation in two groups:there were 5 cases (7.8%) in group B and 20 cases (31.7%) in group A, there was significant difference between two groups (P=0.001). There was no significant difference in lower limb DVT between two groups at 0, 72 and > 72 h after operation(P>0.05), but the formation rate of group A was significantly higher than that of group B at 24 h after operation (P=0.049). There was no significant difference in DVT formation between group A and group B(P>0.05). However, the formation of DVT in group A was significantly higher than that in group B(P=0.012). CONCLUSION Intraoperative IPC combined with 3M thermostat can effectively prevent DVT of lower limbs in patients undergoing PFNA surgery.

Objective To compare the early clinical effects of unilateral biportal endoscopic lumbar interbody fusion (ULIF) and minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF)on single-segment lumbar stenosis with instability. Methods The patients who had single-segment lumbar spinal stenosis with instability and were treated in our hospital from August 2020 to May 2021 were selected.According to the operation methods,they were classified into ULIF group and MIS-TLIF group.The operation duration,hospital stay after operation,perioperative blood loss (drainage volume 48 h after operation,total blood loss),creatine kinase,inflammatory cytokines (C-reactive protein,interleukin-6),D-dimer,and the incidence of lower-extremity venous thrombosis were compared between the two groups.The visual analogue scale and Oswestry disability index were used to evaluate the functional recovery of the two groups in 1 week,1 month,and 3 months after operation. Results The ULIF group had longer operation duration (P<0.001) and shorter hospital stay after operation (P=0.022)than the MIS-TLIF group.The drainage volume 48 h after operation and total blood loss in ULIF group were lower than those in MIS-TLIF group (all P<0.001).The levels of creatine kinase (all P<0.001),C-reactive protein (P<0.001,P=0.002),and interleukin-6 (P=0.003,P<0.001) in ULIF group were lower than those in MIS-TLIF group on the 1st and 3rd day after operation.However,the D-dimer in ULIF group was insignificantly different from that in MIS-TLIF group on the 1st and 3rd day after operation (P=0.117,P=0.683).Lower-extremity venous thrombosis occurred in neither group.The score of visual analogue scale showed no significant difference between the two groups 1 week,1 month,and 3 months after operation (P=0.447,P=0.578,P=0.538),so did the Oswestry disability index (P=0.832,P=0.797,P=0.619). Conclusion ULIF shows similar clinical effect on single-segment lumbar stenosis with instability to MIS-TLIF,which features less bleeding,mild inflammation,mild muscle injury,but long operation duration.

This article presented an overview of the therapeutic effects of Chinese medicine (CM) preparations for promoting blood circulation and removing blood stasis for patients with portal vein thrombosis (PVT) after splenectomy. Based on published clinical researches of CM preparations for PVT after splenectomy in patients with cirrhotic portal hypertension (CPH), this paper evaluated the incidence of PVT, and explored potential active components and mechanisms of CM preparations. Safflower Yellow Injection, Danshen Injection () Danhong Injection (), and Compound Danshen Dropping Pill () achieved good curative effect alone or combined with anticoagulant therapy. In addition, Compound Biejia Ruangan Tablet () and Anluo Huaxian Pill () can also significantly improve the hemodynamic disorders of portal vein system in patients with cirrhosis. Considering the role of CM preparations in ameliorating the incidence of PVT after splenectomy in patients with CPH, we suggested that future research should provide more attention to CM alone or CM combined with anticoagulant for cirrhosis with PVT.

OBJECTIVE: To observe the effect of transcutaneous electrical acupoint stimulation (TEAS) on venous thrombosis and quality of life after lung cancer surgery, basing on the conventional nursing and early functional exercise. METHODS: A total of 120 patients diagnosed as non-small cell lung cancer (NSCLC) and received radical resection of lung cancer surgery for the first time were randomized into a conventional nursing group, a rehabilitation training group and a TEAS group, 40 cases in each group. Conventional nursing was adopted in the conventional nursing group. Conventional nursing combined with early functional exercise were adopted in the rehabilitation training group, the exercise was taken 20 min each time, once in both morning and afternoon for 5 days. On the basis of the treatment in the rehabilitation training group, TEAS was applied at Zusanli (ST 36), Xuehai (SP 10), Sanyinjiao (SP 6), etc. in the TEAS group, with disperse-dense wave in frequency of 30 Hz/100 Hz and tolerable intensity, 30 min each time, once in both morning and afternoon for 5 days. The incidence of venous thrombosis in each group was observed at the 5th day after surgery. Before surgery and at the 5th day after surgery, the Caprini thrombus risk assessment was performed, the Karnofsky performance status (KPS) scale and the functional assessment of cancer therapy-lung (FACT-L) were used to evaluate the quality of life. RESULTS: At the 5th day after surgery, no thrombosis was found in the TEAS group, the incidence of venous thrombosis in the TEAS group was lower than 15.0% (6/40) in the conventional nursing group ( CONCLUSION On the basis of the conventional nursing and early functional exercise, TEAS can reduce the incidence of venous thrombosis, effectively prevent thrombosis and improve quality of life.

The creation of transjugular intrahepatic portosystemic shunt (TIPS) is a widely performed technique to relieve portal hypertension, and to manage recurrent variceal bleeding and refractory ascites in patients where medical and/or endoscopic treatments have failed. However, portosystemic shunt creation can be challenging in the presence of chronic portal vein occlusion. In this case report, we describe a minimally invasive endovascular mesocaval shunt creation with transsplenic approach for the management of recurrent variceal bleeding in a portal hypertension patient with intra- and extrahepatic portal vein occlusion.

Laparoscopic sleeve gastrectomy is a surgical procedure for patients who want to lose weight. An acute porto-mesenteric vein thrombosis is an infrequent but not rare complication in patients who undergo laparoscopic sleeve gastrectomy. In this article, we present a 40-year-old male patient with body mass index of 47 kg/m² was admitted for laparoscopic sleeve gastrectomy. The surgery took about 130 minutes without any hemorrhage. Full enoxaparin prophylaxis, early and full mobilization, and intermittent pneumatic compression stockings were all applied to prevent venous thrombosis. Unfortunately, he applied to our emergency department and diagnosed to have porto-mesenteric vein thrombosis. There was an approximately 60 cm necrotic jejunal segment between 10th and 70th cm after Treitz ligament and was resected. He was discharged on sixth post operative day with prescription of oral warfarin.
