Objective To study the effects of adjuvant Huaier on long-term survivals after curative partial hepatectomy for primary liver cancer.Methods 175 patients with primary liver cancer who received curative partial hepatectomy from January 2002 to January 2006 were divided into two groups:the treatment group (group A,n =87) and the control group (group B,n=88).Group A was treated with Huaier (60 g per day for 6 months) after the operation while group B received no Huaier treatment.Results The overall 1-,3- and 5 year survival rates and disease-free survival rates were 91.90％,73.90％,and 56.0％ and 68.1％,48.4％ and 40.2％,respectively.The overall 1-,3-and 5-year survival rates in group A were significantly higher than group B (91.80％,79.30％,65.2％ vs 92.0％,68.3％,46.6％,P 0.038).In addition,the 1-,3-and 5-year survival rates after tumor recurrence in group A was also significantly higher than group B (78.6％,46.9％,38.2％ vs 69.0％,16.8％,12.6％,P=0.040).Multivariate analysis showed that the use of Huaier,hepatitis infection,severity of cirrhosis,vascular cancer thrombus were the most important prognostic factors for overall long-term survival (P＜0.05).Blood transfusion and histological grade were independent risk factors for disease free survival.The use of Huaier and the clinicopathological type were significantly co-related to the survival from recurrence/metastasis to death.Conclusion The use of Huaier improved disease free survival and the survival from recurrence or metastasis for patients with primary liver cancer following curative hepatectomy.

Objective To investigate the clinical therapeutic methods and their curative effects in recurrent ischemic angina for internal mammary artery resterosis after coronary artery bypass grafting (CABG).Methods We enrolled the patients who had recurrence of ischemic angina for restenosis of internal mammary artery graft after CABG as research subjects in the Affiliated Hospital of Yan'an University from January 2014 to January 2016.The 42 patients were divided into three groups according to the different treatment approaches for recurrence of ischemic angina:Group A (n=22)who received internal mammary artery interventional therapy;Group B (n=12)who received coronary artery bypass grafting treatment;and Group C (n=8)who received left subclavian artery proximal stent treatment.Then we compared the clinical therapeutic effects in the three groups.Results The success rate in Group C was 100%,which was the highest in the three groups,and the post-operative restenosis rate was 0.The hospitalization time was significantly shorter in Group A than in Group B (P＜0.05).However,the two groups did not significantly differ in mortality,success rate or restenosis rate (P＞0.05).Conclusion We should select the appropriate treatment according to the patient's specific situation for recurrent ischemic angina. Endovascular treatment has evident therapeutic effects,rapid postoperative recovery,and lower treatment risk, making it the preferred treatment when possible.

Objective: This study aimed to assess the technical feasibility, efficacy, and safety of the safe triangular working zone (STWZ) approach applied in percutaneous vertebroplasty (PV) for spinal metastases involving the posterior part of the vertebral body. Materials and Methods: We prospectively enrolled 87 patients who underwent PV for spinal metastasis involving the posterior part of the vertebral body, with or without the STWZ approach, from January 2019 to April 2022. Forty-nine patients (27 females and 22 males; mean age ± standard deviation [SD], 57.2 ± 11.6 years; age range, 31–76 years) were included in group A (with STWZ approach), accounting for 54 vertebrae. Thirty-eight patients (18 females and 20 males; 59.1 ± 10.9 years; 29–81 years) were included in group B (without STWZ approach), accounting for 57 vertebrae. Patient demographics, procedure-related variables, and pain relief as assessed using the visual analog scale (VAS) were collected at different time points. Tumor recurrence in the vertebrae after PV was analyzed using Kaplan–Meier curves. Results: The STWZ approach was successful from T1 to L5 without severe complications. Cement filling was satisfactory in 47/54 (87.0%) and 25/57 (43.9%) vertebrae in groups A and B, respectively (v< 0.001). Cement leakage was not significantly different between groups A and B (p= 1.000). Mean VAS score ± SD before and 1 week and 1, 3, 6, 9, and 12 months after PV were 7.6 ± 1.8, 4.2 ± 2.0, 2.7 ± 1.9, 1.9 ± 1.5, 1.7 ± 1.4, 1.7 ± 1.1, and 1.6 ± 1.3, respectively, in group A and 7.2 ± 1.7, 4.0 ± 1.3, 3.4 ± 1.6, 2.4 ± 1.2, 1.8 ± 1.0, 1.4 ± 0.5, and 1.7 ± 0.9, respectively, in group B. Kaplan–Meier analysis showed a lower tumor recurrence rate in group A than in group B (p = 0.001). Conclusion The STWZ approach may represent a new, safe, alternative/auxiliary approach to target the posterior part of the vertebral body in the PV for spinal metastases.

OBJECTIVETo investigate the prognostic factors of hepatocellular carcinoma.

METHODSThe purpose of this study was to retrospectively analyze the surgical outcomes of hepatocellular carcinoma (HCC) in 832 patients who underwent hepatic resection between February 2002 and June 2010 in the Cancer Hospital of Chinese Academy of Medical Sciences. Post-resection prognostic factors were assessed using a univariate Kaplan-Meier analysis and a multivariate Cox proportional hazards model.

RESULTSThe overall 1-, 3- and 5-year survival rates were 92.0%, 70.2% and 53.6%, respectively. The disease free survival rates (DFS) were 90.2%, 61.5% and 40.5%, respectively. The univariate analysis showed that a better prognosis for overall survival (OS) was associated with asymptomatic presentation, small tumor, single lesion, high-grade histological differentiation, no vascular tumor embolus, negative serum alpha-fetoprotein (AFP), negative serum alkaline phosphatase (ALP), Child-Pugh class A, no ascites, no/mild cirrhosis, new surgical techniques, no blood transfusion, no regional lymph node metastasis, no major vascular invasion, and no extra-hepatic invasion. The multivariate analysis showed that asymptomatic presentation, small tumor, single lesion, no tumor embolus, negative serum alpha-fetoprotein (AFP), no regional lymph node metastasis, no major vascular invasion, no extra-hepatic invasion, no/mild cirrhosis, and surgical techniques are independent factors for a longer overall survival.

CONCLUSIONSThe prognosis of HCC after resection is influenced by a number of factors. Therefore, regularly screening and early diagnosis, applying surgical techniques to minimize the liver injury, and preventing the aggravation of cirrhosis are important measures to improve the overall survival of HCC patients. For those patients with high risk factors of recurrence, routine follow-up is one of the best methods to be recommended.

OBJECTIVETo investigate the influence of combined hepatectomy with splenectomy on safety of operation for hepatocellular carcinoma patients complied with cirrhosis and hypersplenism and the best peri-operative treatment of these patients.

METHODSClinical data of 177 hepatocellular carcinoma patients complied with cirrhosis and hypersplenism admitted from January 1999 to December 2009 were analyzed retrospectively. Among which, 71 patients received concomitant splenectomy with hepatectomy (splenectomy group), 106 patients only receive a hepatectomy (non-splenectomy group). The safety of operation, complications, liver function and WBC and PLT counts were compared between the two groups.

RESULTSThere was no significant difference of general conditions, counts of WBC and PLT between the two groups before operation. The counts of PLT at 1, 10, 30 day after operation were (88.4 ± 23.6) × 10⁹/L, (345.3 ± 98.2) × 10⁹/L and (210.8 ± 92.2) × 10⁹/L respectively in splenectomy group, which were significantly higher than that of non-splenectomy group (P < 0.05). The operation time of splenectomy group was (216 ± 105) min, which was longer than that of non splenectomy group (P < 0.05), but the blood loss and transfusion rate had not significantly difference between the two groups. The complication rates of splenectomy group and non-splenectomy group were 11.3% and 6.6% respectively, there was no significant difference between the two groups.

CONCLUSIONCombined hepatectomy with splenectomy will be safe for hepatocellular carcinoma patients complied with cirrhosis and hypersplenism as if the operative indication and increase the ability of peri-operative treatment are strictly obeyed.

OBJECTIVEHigh short-term successful rate was reported for catheter ablation in patients with paroxysmal atrial fibrillation (AF), we analyzed the long-term outcome (success rate, anticoagulation therapy and embolism event, anti-arrhythmic therapy and death post procedure) of catheter ablation for paroxysmal AF in this study.

METHODSFrom January 2000 to December 2004, 106 consecutive patients with drug-refractory paroxysmal AF underwent catheter ablation and were followed-up for (60.7 + or - 11.8) months. Segmental pulmonary vein isolation (SPVI) was routinely performed by radiofrequency energy under the guidance of circular mapping catheter. The patients were followed up with 24 h-holter, ECG, telephone or letter. Data on recurrence of AF, the anticoagulation medication and the incidence of embolism, anti-arrhythmic therapy were obtained.

RESULTSThere were 9 patients lost to follow up. In the remaining 97 patients [65 males, (54.8 + or - 11.2) years old], 3 cases died from cancer, sinus rhythm was maintained in 68 patients (Group S, 72.3%) and AF recurrence evidenced in 26 patients (Group R, 27.7%). In Group S, 56 patients (82.4%) discontinued anticoagulation medication, and 12 patients continued to take aspirin. There was no embolism event in Group S during follow-up. In Group R, 1 patient continued to take warfarin; 11 patients continued to take aspirin and 2 patients suffered from cerebral embolism. Anticoagulation medication was discontinued in 14 patients (53.8%) and 1 patient suffered form cerebral embolism. The incidence of embolism event in Group R is significantly higher than in Group S (P < 0.01). More patients discontinued anti-arrhythmic medication in Group S than in Group R (80.9% vs. 56.0%, P < 0.05).

CONCLUSIONCatheter ablation is associated with satisfactory long-term success rate, reduced anti-arrhythmia medication, improved quality of life in patients with paroxysmal AF.

Objective To assess the limit of detection(LOD),sensitivity and specificity of collodial gold immunochrom-atography(GICA)products purchased from two manufacturers under special environmental conditions.Methods The sensitivity and specificity of GICA made in InTec Products, INC.and Beijing WANTAI Biological Pharmacy Enterprise Co., LTD.for detecting HBsAg, anti-HCV and anti-Treponema pallidum(TP)serum samples were evaluated under different conditions(conventional facilities,simulated hot and humid environments and simulated low pressure and hypoxia environments)according to the protocol of kits.LOD was estimated by detecting the standard materials obtained from the National Center for Clinical Laboratory(NCCL)of China.Results LOD for syphilis improved from 2 NCU to 1 NCU using GICA from InTec Products in hot and humid environments.The extreme conditions did not influence the specificity of GICA from the two manufacturers in the course of detection of clinical samples,but the sensitivity of detection was affected.For InTec Products,the sensitivity of hepatitis B virus and syphilis detection was improved in hot and humid environments,but was reduced in low pressure and hypoxia environments.In addition,the sensitivity of hepatitis C virus detection by InTec Products decreased in hot and humid environments.As for WANTAI products,the sensitivity of hepatitis B virus detection was reduced under extreme conditions and that of hepatitis C virus was only influenced by hot and humid environments. Interestingly, extreme conditions had no impact on the sensitivity of syphilis.Conclusion LOD of InTec Products is better than that of the WANTAI products for detection of standard materials from blood-borne diseases.In the process of detecting clinical samples,the sensitivity of the two manufacturers′GICA is influenced by extreme conditions, with the specificity unchanged.Overall, WANTAI products are more stable than those of InTec, and are also less influenced by extreme conditions.

Objective To discuss the clinical curative effect of percutaneous vertebroplasty(PVP)combined with percutaneous pedicle screw fixation for thoracolumbar fracture.Methods Retrospectively analyzed the clinical data of 43 patients with thoracolumbar fracture who underwent PVP combined with percutaneous pedicle screw fixation in our hospital from November 2015 to June 2017.Those patients included 28 males and 15 females,and the age of patients ranged from 50 to 66 years old,with an average age of(58.26 ±3.67)years old.The func-tional outcome were evaluated by VAS scores and ODI scores before and after the operation.The sagittal Cobb angle was used to evaluate the reduction of fracture.Results All these patients all successfully completed the operation,and there was no complications after operation.The operation time ranged from 60 to 126 min,with an average time of(96.07 ±15.69)min;the blood loss ranged from 60 to 180 min,with an average time of(113.26 ±24.7)min.All the patients were followed up for 4 to 23 months,with an average time of(12.07 ±4.01)months. The VAS score,ODI score and sagittal Cobb angle were significantly decreased in the last follow -up period compared with those before surgery,and the difference was statistically significant(P<0.05).Conclusion PVP combined with percutaneous pedicle screw fixation in the treatment of thoracolumbar fracture has smaller incision,less blood loss,shorter operation time and better improvement of local pain,func-tional movement and kyphosis.

Objective:To explore the effect of timely induction intervention on postpartum urination in primipara during vaginal delivery, so as to provide the evidence for preventing the occurrence of postpartum urinary retention and relieving the pain of primipara.Methods:This study adopted a randomized controlled trial design, and selected 400 cases of primipara who were hospitalized for vaginal delivery in the Obstetric Department of Dalian Women and Children's Medical Group Sports New Town Hospital from June 2021 to September 2022 as the study objects by convenience sampling method. They were divided into the intervention group and the control group with 200 cases each by random number table method, and the control group received routine postpartum care. Instruct active urination within 6 hours after delivery. The intervention received timely induction urination intervention. The general condition and bladder urine volume of the women in the intervention group were evaluated at 2, 4, 6 h after delivery, respectively, and personalized guidance was implemented, including the frequency of massage of the bottom of the uterus, the control of water intake, the selection of methods and timing of inducing urination, etc., and routine postpartum care was given when the women completed their first urination and had no complaints of discomfort. The first urination time, first urination volume, first bladder irritation during the first urination and the incidence of postpartum urinary retention in different periods were compared between the two groups.Results:The patients in the control group were (29.60 ± 3.20) years old, while the patients in the intervention group were (28.81 ± 3.42) years old. The first urination time in the intervention group was (6.89 ± 2.18) h, which was shorter than that in the control group (9.11 ± 3.86) h, and the difference was statistically significant ( t=-2.49, P<0.01). The first urination volume in the intervention group was (322.36 ± 120.15) ml, which was higher than that in the control group (262.93 ± 105.68) ml, and the difference was statistically significant ( t=3.39, P<0.05). The incidence of the first bladder irritation in the intervention group was 22.0%(44/200), which was lower than that in the control group 33.5%(67/200), and the difference was statistically significant ( χ2=6.60, P<0.05). The incidence of postpartum urinary retention within 24 h in the intervention group was 5.5%(11/200), which was lower than that in the control group 11.5%(23/200), and the difference was statistically significant ( χ2=4.63, P<0.05). The incidence of postpartum urinary retention within 1 week in the intervention group was 9.5%(19/200), which was lower than that in the control group 16.5%(33/200), and the difference was statistically significant ( χ2=4.33, P<0.05). There was no significant difference in the incidence of postpartum urinary retention within 24 to 72 h between the two groups ( P>0.05). Conclusions:Timely induction intervention can reduce the incidence of postpartum urinary retention, shorten the time of first urination, increase the volume of first urination and improve the comfort of first urination, which is worthy of clinical application.
