ABSTRACT
Objective:To characterize the geriatric osteoporotic pelvic fractures using 3-D computed tomography (CT) fracture mapping.Methods:Retrospectively analyzed were the 79 elderly patients with pelvic fracture who had been admitted to Department of Orthopaedics, The 7th Medical Center of PLA General Hospital between January 2017 and December 2021. There were 24 men and 55 women, aged from 60 to 98 years (average, 74.3 years). The CT scan data of the pelvis from all patients were imported into the software (Mimics Medical 18.0, Geomagic Studio 2014, Rhinoceros 6.0, and Matlab) to create a 3-D pelvic fracture model. The fracture pieces were imported into a standard pelvic template to obtain the morphology of the fracture lines after fitting. A map of fracture line distribution frequency and a fracture heat map were created by fitting the fracture lines of all patients into a common pelvic template.Results:Of the 79 elderly patients with pelvic fracture, 69 (87.3%) had fractures of both the anterior and the posterior rings. The fracture map and heat map of geriatric pelvic fractures showed the following: the fracture lines of the anterior ring were concentrated in the junction of the cancellous bone and cortical bone of the superior and inferior pubic rami; the fracture lines of the posterior ring were concentrated in the middle and posterior 1/3 of the ilium and in the sacral wing; the fracture frequencies incurred by the pubic bone, sacrum, and ilium were from the highest to the lowest.Conclusions:Fracture mapping can visually characterize the distribution of fracture lines of the geriatric pelvic fractures. Simultaneous fractures of the anterior and posterior rings of the pelvis are the most typical kind of pelvic fractures in the elderly. The junction of the cancellous and cortical bones of the superior and inferior pubic rami and the area surrounding the sacroiliac joint are the most frequent locations for the fractures.
ABSTRACT
Objective:To evaluate clinical outcomes and complications of minimal invasive surgery for the treatment of elderly patients with fragility fracture of pelvis.Methods:Elderly patients with fragile pelvic fractures undergoing minimally invasive surgery and being followed up were retrospectively analyzed from January 2015 to December 2019.Based on the classification of pelvic fragile fractures(FFP), open reduction and internal fixation with pelvic anterior ring instability internal fixator(INFIX)plus posterior ring sacroiliac screw, or open reduction and internal fixation with iliac fossa approach, were performed for elderly patients with fragile pelvic fractures.The general data of all patients(age, sex, mechanism of injury)were recorded.Time from injury to operation, VAS(visual analogue scale)before and after operation, blood loss during operation, complications during hospitalization, time to ambulation, mortality, and Koval walking index at 2 year follow-up were recorded to evaluate clinical outcomes and complications of minimal invasive surgery for the treatment of fragility fracture of pelvis.Results:Thirty-two patients were followed up, including 11 males and 21 females, aged 65-88 years(76.9±5.5)years.The mechanism of injury was fall on the ground as a percentage of 59.4%(19/32), fall in the sitting position as a percentage of 25.0%(8/32), and 15.63%(5/32)had unknown history of trauma.The time from injury to operation was 3-36 days(9.6±3.3)days.There were 50.0%(16/32)type Ⅱ, 31.3%(10/32)type Ⅲ and 18.8%(6/32)type Ⅳ cases according to FFP classification.The mean blood loss during operation was(65.9±35.2)ml(range, 20-200 ml). The preoperative VAS score was 5-9 scores, with an average of(6.41±1.07)scores.The postoperative VAS score was 1-4(1.71±0.63). Average time from injury to operation was(9.6±3.3)days(range, 3~36). The incidence of complications during operation was 9.4%(3/32), including 1 case of gastrointestinal bleeding, 1 case of lower extremity deep vein thrombosis, and 1 case of superficial wound infection.Ambulation was at 4 weeks post-operation in 56.3%(18/32)cases, at 6 weeks post-operation in 31.3%(10/32)cases and at 8 weeks post-operation in 12.5%(4/32)cases.6.25%(2/32)patients died within 2 year follow-up.Koval walking index of the rest 30 patients included grade 1 in 46.9%(15/32)cases, grade 2 in 18.8%(6/32)cases, grade 3 in 6.3%(2/32)cases, grade 4 in 18.8%(6/32)cases and grade 6 in 3.1%(1/32)case(1 year after surgery, hemiplegia after cerebral infarction).Conclusions:Minimal invasive surgery achieves significant pain relief and early mobilization in patients with fragility fracture of pelvis.
ABSTRACT
Objective:To investigate the efficacy and safety of laparoscopic versus open surgery for early cervical cancer and analyze the factors that influence laparoscopic surgery for early cervical cancer. Methods:The clinical data of 411 patients with International Federation of Gynecology and Obstetrics (FIGO)stage IA1-IIA2 cervical cancer who received treatment in Liuzhou Worker's Hospital, China between January 1, 2000 and August 31, 2016 were retrospectively analyzed. The clinical data were divided into laparoscopic surgery ( n = 320) and open surgery ( n = 91) groups according to surgical approaches. The operation time, intraoperative injury, intraoperative blood loss, time to first postoperative anal exhaust, postoperative complications, time to extubation, and postoperative recurrence rate were compared between laparoscopic surgery and open surgery groups. Multivariable COX regression analysis was performed to analyze the recurrence of cervical cancer after laparoscopic surgery. Results:The operation time in the laparoscopic surgery group was significantly shorter than that in the open surgery [(223.4 ± 53.2) min vs. (251.0 ± 50.0) min, t = 20.200, P < 0.05]. The intraoperative blood loss, time to extubation and the time to first postoperative anal exhaust in the laparoscopic surgery group were less or shorter than those in the open surgery group (all P < 0.05). Under the premise that there were no significant differences in vascular and lymphatic space invasion, tumor size, parametrial invasion, depth of muscle invasion, lymph node metastasis, and vaginal margin between the laparoscopic surgery and open surgery groups, the 1-year and 3-year recurrence rate of cervical cancer was 9.4% (30/320) and 15.9% (51/320), respectively and the 1-year and 3-year tumor-free survival rate was 90.6% and 84.1%, respectively in the laparoscopic surgery group; the 1-year and 3-year recurrence rate of cervical cancer was 4.4% (4/91) and 9.9% (9/91), respectively and the 1-year and 3-year tumor-free survival rate was 95.6% and 89.6%, respectively in the open surgery group. There were no significant differences in 1-year and 3-year recurrence rate of cervical cancer and 1-year and 3-year tumor-free survival rate between laparoscopic surgery and open surgery groups (all P > 0.05). During the 5-year follow-up, there were no significant differences in the recurrence rate of cervical cancer (18.7% vs. 12.2%) and the tumor-free survival rate (81.9% vs. 86.8%) between the laparoscopic surgery and open surgery groups (both P > 0.05). Univariate and multivariate analysis showed that positive lymph node metastasis, tumor size ≥ 2 cm, FIGO stage > IB1 and non-squamous cell carcinoma pathological type are the risk factors for the recurrence of cervical cancer. Conclusion:Laparoscopic surgery for early cervical cancer can reduce the intraoperative and postoperative complications. Positive lymph node metastasis, tumor size ≥ 2 cm, FIGO stage > IB1, and non-squamous cell carcinoma pathological type are the risk factors of recurrence of cervical cancer after laparoscopic surgery.

Meta-analysis was performed by RevMan5.3 software. 【Results】 A total of 28 049 patients in 12 literature were included, 1 190 patients were included into the ART group and 26 859 into the non-ART group. Meta-analysis results showed that the incidence of ART was 1.63% (410/24 361), mainly allergic reaction (43.90%, 188/410) and non-hemolytic fever (40%, 164/410). Primary hematologic disease (OR=27.11, 95%CI=21.64~33.96, P 2 (OR=7.06, 95% CI=5.64~8.84, P30 min interval between blood issuing and transfusion (OR=3.40, 95% CI=2.88~4.00, P2, >30 min interval between blood issuing and transfusion, transfusion of plasma and cryoprecipitates, while transfusion of red blood cells/white blood cells/platelets was the protective factor.
ABSTRACT
Objective:To evaluate the clinical outcomes of Acumed intramedullary nailing for AO type A3 forearm diaphyseal fracture in adults.Methods:A retrospective study was conducted of the 20 adult patients with AO type A3 forearm diaphyseal fracture who had been treated by Acumed intramedullary nailing from January 2016 to November 2018 at PLA General Hospital. They were 18 males and 2 females, aged from 18 to 56 years (average, 36.5 years). There were 6 radius diaphyseal fractures, 9 ulna diaphyseal fractures and 5 diaphyseal fractures of both forearm bones. The clinical outcomes of Acumed intramedullary nailing for AO type A3 forearm diaphyseal fractures were evaluated by recording the perioperative complications, fracture union time, forearm rotation range at 12-month follow-up, and Disability of the Arm, Shoulder and Hand Questionnaire (DASH) scores for the upper limb function.Results:The 20 patients were followed up for 12 to 18 months (mean, 15.8 months). Bony union was achieved in all the patients after 3 to 4 months (average, 3.3 months). Partial rupture of the extensor pollicis longus tendon happened during operation in one patient and at 3 months post-operation in another due to fixation irritation, and linear ossification of interosseous membranes was observed in one patient with diaphyseal fractures of both forearm bones. 12-month follow-ups showed that, in the 20 patients, forearm pronation ranged from 80° to 90° (average, 89°), supination from 60° to 90° (average, 86.3°) and DASH scores from 0 to 37 (average, 6.5).Conclusions:In the treatment of AO type A3 forearm diaphyseal fracture in adults, Acumed intramedullary nailing can lead to successful fracture union and excellent rotational activity at one year after operation. Therefore, adult AO type A3 forearm diaphyseal fracture can be listed as an indication for Acumed intramedullary nailing.
ABSTRACT
Pelvic fragility fractures are increasing with the aging population in China, characterized by high incidence, high mortality and high morbidity just as geriatric hip fractures. In diagnosis of a pelvic fragility fracture in the elderly, the patient＇s age, comorbidities, osteogenic factors, clinical manifestations and imaging examinations should be taken into consideration, as well as the special anatomical features and morphologies resulted from degenerative anatomy of the pelvis in the aged. Standard pelvic X-rays and CT scans may confirm the diagnosis in most cases, but MRI may prevent missing a fracture of malfunctioning pelvis or an insidious fracture line on the posterior ring. Fragility fractures of pelvis (FFP) classification, base on X-ray and CT checks, is a common guiding system in current clinic. Usually, conservative treatment is indicated for fractures of FFP types Ⅰ-Ⅱ while surgery for those of FFP types Ⅲ-Ⅳ. As far as possible, minimally invasive reduction and simultaneous fixation of the anterior and posterior rings are recommended. This article intends to review the characteristics, classification and development of minimally invasive techniques concerning pelvic fragility fractures in recent years, and to discuss the future trends in treatment of geriatric pelvic fractures.
ABSTRACT
Objective:To investigate the characteristics of fragility fractures of pelvis(FFP) in the elderly and compare the clinical efficacy between conservative treatment and minimally invasive surgery.Methods:A retrospective study was conducted in the 56 elderly FFP patients who had been treated at Department of Orthopaedics, The General Hospital of Chinese People＇s Liberation Army from January 2017 to January 2019. They were 16 males and 40 females, with an age of 73.4 years (from 65 to 93 years). By the American Society of Anesthesiologists (ASA) classification, there were 12 cases of grade Ⅰ, 16 cases of grade Ⅱ, 20 cases of grade Ⅲ, and 8 cases of grade Ⅳ; by the FFP classification, there were 6 cases of type Ⅰ, 10 cases of type Ⅱ, 36 cases of type Ⅲ, and 4 cases of type Ⅳ. The morphological characteristics and injury mechanisms of FFP were analyzed. According to the treatment methods, the patients were divided into a conservative treatment group of 32 cases and a minimally invasive surgery group of 24 cases. The 2 groups were compared in terms of complication incidence, mortality and the Koval attenuation rate of walking ability after one-year follow-up.Results:There were mostly the fractures of pubic branches on both sides of the pubic symphysis and compression fractures of the sacral wing caused by lateral crush injury. The 2 groups were comparable due to no significant differences in the preoperative general data between them other than FFP classification ( P>0.05). By one year after treatment, the conservative treatment group had a complication incidence of 34.4% (11/32), a mortality of 9.4% (3/32) and a Koval attenuation rate of walking ability of 13.8% (4/29) while the minimally invasive surgery group had a complication incidence of 20.8% (5/24), a mortality of 4.2% (1/24) and a Koval attenuation rate of walking ability of 8.7%(2/23), showing no significant difference between the 2 groups ( P>0.05). Conclusions:The injury mechanism of geriatric FFP is mostly lateral compression injury. The fracture sites are mostly located on both sides of the pubic symphysis, pubic branches and the sacral wing of anterior and posterior rings simultaneously. Although there may be no significant difference in complication incidence, mortality or Koval attenuation rate of walking ability between conservative treatment and minimally invasive surgery after one year, the minimally invasive surgery deals with more unstable fracture types.
ABSTRACT
Objective@#To investigate the clinical efficacy of radical resection for stage T3 gallbladder cancer and prognostic factors.@*Methods@#The retrospective case-control study was conducted. The clinico-pathological data of 87 patients with T3 gallbladder cancer who were admitted to Tianjin Medical University Cancer Institute and Hospital from January 2005 to June 2016 were collected. There were 44 males and 43 females, aged 29-79 years, with a median age of 61 years. According to the different preoperative pathological classification and intraoperative exploration of gallbladder cancer, corresponding surgeries were performed. Observation indicators: (1) surgical and postoperative conditions; (2) clinical efficacy of stage T3 gallbladder cancer and prognostic factors analysis; (3) clinical efficacy of stage T3 gallbladder adenocarcinoma and prognostic factors analysis; (4) clinical efficacy of stage T3 gallbladder adenosquamous carcinoma and prognostic factors analysis. Follow-up by outpatient examination or telephone interview was performed to detect the postoperative survival of patients up to June 2018. Measurement data with skewed distribution were represented as M (range), and count data were described as absolute numbers. Survival curve, survival time and survival rate were drawn and calculated by the Kaplan-Meier method. Survival analysis was performed by the Log-rank test. Univariate analysis was performed using the Log-rank test and multivariate analysis using the COX proportional hazard model.@*Results@#(1) Surgical and postoperative conditions: all the 87 patients underwent radical resection of gallbladder cancer, including 29 cases of hepatic wedge resection and 58 cases of extended hepatectomy. Of the 87 patients, 42 underwent standard lymph node dissection and 45 underwent enlarged lymph node dissection. There were 27 cases receiving extrahepatic bile duct reconstruction. The postoperative pathological results of 87 patients showed that 64 were diagnosed with gallbladder adenocarcinoma and 23 were diagnosed with gallbladder adenosquamous carcinoma. There were 59 cases comorbid with liver invasion and 3 cases comorbid with vascular invasion. The marginal histopathological examination showed negative margin in 63 cases and positive margin in 24 cases. The degree of tumor differentiation: there were 23 patients with highly differentiated tumor and 64 with poorly differentiated tumor. Of the 87 patients, 43 received postoperative adjuvant therapy and 44 didn′t receive adjuvant therapy. (2) Clinical efficacy of stage T3 gallbladder cancer and prognostic factors analysis. ① All the 87 patients were followed up for 1.8-128.0 months, with a median follow-up time of 26.3 months. All the 87 patients had survived for 1.1-82.7 months, with a median time of 20.1 months. The 2-year overall survival rate of patients was 59.8%, and the 2-year disease-free survival rate was 49.4%. ② Univariate analysis showed that preoperative alkaline phosphatase (ALP) level, tumor diameter, pathological type of tumor, lymph node metastasis, and range of hepatectomy were associated factors for the postoperative 2-year overall survival rate of patients (χ2=5.451, 4.900, 8.256, 4.419, 5.858, P<0.05), and pathological type of tumor, lymph node metastasis, and range of hepatectomy were associated factors for the postoperative 2-year disease-free survival rate of patients (χ2=5.828, 6.968, 4.077, P<0.05). Multivariate analysis showed that preoperative ALP level, tumor diameter, and lymph node metastasis were independent factors influencing the postoperative 2-year overall survival rate of patients [hazard ratio (HR)=2.539, 2.619, 2.201, 95% confidence interval (CI) : 1.174-5.491, 1.209-5.673, 1.104-4.391, P<0.05)]; pathological type of tumor and lymph node metastasis were independent factors influencing the postoperative 2-year disease-free survival rate of patients (HR=2.254, 2.296, 95%CI: 1.170-4.344, 1.206-4.374, P<0.05). ③ Survival analysis: pathological type of tumor was an associated factor for the postoperative 2-year overall survival rate and 2-year disease-free survival rate of patients. Of the 87 patients with T3 gallbladder cancer, there was no significant difference in the postoperative 2-year overall survival rate between the 64 patients with gallbladder adenocarcinoma and 23 with gallbladder adenosquamous carcinoma (68.8% vs. 34.8%, χ2=8.256, P>0.05), but a significant difference in the postoperative 2-year disease-free survival rate between them (56.3% vs. 30.4%, χ2=5.828, P<0.05). (3) Clinical efficacy of stage T3 gallbladder adenocarcinoma and prognostic factors analysis. ① Sixty-four patients with gallbladder adenocarcinoma had the median survival time of 23.1 months, with a range from 3.2 to 82.7 months. The postoperative 2-year overall survival rate was 68.8%, and the postoperative 2-year disease-free survival rate was 56.3%. ② For the 64 patients with T3 stage gallbladder adenocarcinoma, univariate analysis showed that preoperative CA19-9 level and range of lymph node dissection were associated factors for the postoperative 2-year overall survival rate (χ2=4.012, 8.837, P<0.05). The range of lymph node dissection was an associated factor for the postoperative 2-year disease-free survival rate (χ2=6.361, P<0.05). Multivariate analysis showed that range of lymph node dissection was an independant factor for both the postoperative 2-year overall survival rate and postoperative 2-year disease-free survival rate (HR=0.244, 0.382, 95%CI: 0.088-0.674, 0.176-0.831, P<0.05). ③ Survival analysis: range of lymph node dissection was an associated factor for both the postoperative 2-year overall survival rate and postoperative 2-year disease-free survival rate of patients. Of the 64 patients with T3 stage gallbladder adenocarcinoma, the postoperative 2-year overall survival rate and disease-free survival rate of patients undergoing enlarged lymph node dissection were 84.8% and 69.7%, versus 51.6% and 41.9% of the patients undergoing standard lymph node dissection (χ2=8.837, 6.361, P<0.05). (4)Clinical efficacy of stage T3 gallbladder adenosquamous carcinoma and prognostic factors analysis. ① Twenty-three patients with gallbladder adenosquamous carcinoma had the median survival time of 13.2 months, with a range from 1.1 to 70.3 months. The postoperative 2-year overall survival rate was 34.8%, and the postoperative 2-year disease-free survival rate was 30.4%. ② For the 23 patients with T3 stage gallbladder adenosquamous carcinoma, univariate analysis showed that preoperative ALP level, lymph node metastasis, range of hepatectomy, and extrahepatic bile duct reconstruction were associated factors for the postoperative 2-year overall survival rate of patients (χ2=5.288, 4.574, 12.960, 4.106, P<0.05). The lymph node metastasis and range of hepatectomy were associated factors for the postoperative 2-year disease-free survival rate of patients (χ2=7.364, 10.582, P<0.05). Multivariate analysis showed that range of hepatectomy was an independant factor for both the postoperative 2-year overall survival rate and postoperative 2-year disease-free survival rate (HR=0.102, 0.153, 95%CI: 0.012-0.880, 0.033-0.718, P<0.05). ③ Survival analysis: range of hepatectomy was an independant factor for both the postoperative 2-year overall survival rate and postoperative 2-year disease-free survival rate of patients. Of the 23 patients with T3 stage gallbladder adenosquamous carcinoma, the postoperative 2-year overall survival rate and postoperative 2-year disease-free survival rate of patients undergoing extended hepatectomy were 87.5% and 75.0%, versus 6.7% and 6.7% of the patients undergoing hepatic wedge resection (χ2=12.960, 10.528, P<0.05).@*Conclusions@#Lymph node metastasis is an independent factor influencing the postoperative 2-year overall survival rate and postoperative 2-year disease-free survival rate of patients with T3 stage gallbladder cancer. The range of lymph node dissection is an independent factor for the postoperative 2-year overall survival rate and postoperative 2-year disease-free survival rate of patients with stage T3 gallbladder adenocarcinoma. Range of hepatectomy is an independent factor for the postoperative 2-year overall survival rate and postoperative 2-year disease-free survival rate of patients with stage T3 gallbladder adenosquamous carcinoma. Patients with gallbladder adenocarcinoma should undergo enlarged lymph node dissection, and patients with gallbladder adenosquamous carcinoma need to undergo extended hepatectomy.

Objective To compare the efficacy of radiofrequency ablation versus surgical resection in treatment of colorectal liver metastases with a maximum diameter ≤ 3 cm and a number ≤ 3, and to analyze the risk factors of recurrence. Methods The data of 97 patients with colorectal liver metastases from January 2012 to June 2016 treated at Tianjin Medical University Cancer Institute and Hospital were analyzed retrospectively. There were 66 males and 31 females. The patients were divided into the radiofre-quency ablation group (23 patients) and the surgical resection group ( 74 patients). The patients were followed up. The clinicopathological features of the two groups before treatment were compared. Kaplan-Meier curves were drawn, and the recurrence-free survival curve and overall survival curve of the two groups were compared by log-rank test. Univariate and multivariate Cox regression analysis was used to analyze the risk factors of recurrence. Results There were no significant differences in age, location of primary tumor, number and size of liver metastases, and preoperative carcinoembryonic antigen level between the two groups (P＞0. 05). On the date this study was censored, there were 50 patients who had developed recurrence in the surgical resection group and 22 patients in the ablation group, (67. 6% vs. 95. 7% ). The difference was significant (P＜0. 05). The 1-and 2-year recurrence-free survival rates were 54. 6% and 39. 0% in the surgical resection group and 39. 1% and 8. 7% in the radiofrequency ablation group, respectively. The difference was significant (P＜0. 05). There was no local recurrence in either of the two groups. There was no significant difference in the overall survival curves between the two groups (P＞0. 05). Univariate and multivariate analysis showed that N 1 ～2 staging (HR=1. 908, 95% CI: 1. 094～3. 325), simultaneous liver metastasis (HR=1. 662, 95% CI: 1. 024～2. 695) and radiofrequency ablation (HR=2. 708, 95% CI: 1. 589～4. 617) were independent risk factors of recurrence for colorectal liver metastasis. Conclusions Radiofrequency ablation can achieve complete ablation in patients with colorectal liver metastases with maximum diameter ≤3 cm and number≤3, but the recurrence rate of radiofrequency ablation is significantly higher than that of surgical resection. N 1 ～2 staging, simultaneous liver metastasis and radiofrequency ablation were independent risk factors for recurrence of colorectal liver metastasis.
ABSTRACT
Objective:To compare the relationship between the operative strategies and clinical outcomes of type Ⅲ and Ⅳ hilar chol-angiocarcinomas(HCs).Methods:We retrospectively analyzed the clinical data and long-term outcomes for 50 cases of type Ⅲ and Ⅳ HC that underwent surgery at the Tianjin Medical University Cancer Hospital.Results:Fifty patients were followed up and the median follow-up duration was 27 months.The hilar limited hepatectomy group included 13 cases;the median disease-free survival was 6 months,and 1-and 2-year disease-free survival rates were 30.8% and 23.1%,respectively.The median overall survival was 20 months, and the 1-and 2-year overall survival rates were 76.9% and 38.5%,respectively.The extended hepatectomy group included 37 cases;the median disease-free survival was 14 months,and 1-and 2-year disease-free survival rates were 59.5% and 32.4%,respectively.The median overall survival was 37 months,and the 1-and 2-year overall survival rates were 83.8% and 51.4%,respectively.Compared with the hilar limited hepatectomy group,the extended hepatectomy group had significantly longer median disease-free and overall survival(P<0.05).The 1-and 2-year disease-free and overall survival rates were higher for the extended hepatectomy group.There was no significant difference in morbidity and mortality between the two groups(P>0.05).Conclusions:Extended hepatectomy is a safe operation that delays recurrence at early time points and improves the prognosis for patients with type Ⅲ and Ⅳ HC.
ABSTRACT
Objective To observe the long-term mortality in the elderly patients with hip fracture and evaluate its associated risk factors.Methods Included in this retrospective analysis were the eligible patients who had been treated for hip fracture at Department of Orthopedics,General Army Hospital of PLA from January 2012 to December 2013.Their clinic data were documented,including age,gender,coexisting disease,American Society of Anesthesiologists (ASA) rating,fracture type,operation time and operation pattern.The patients included were divided into 2 groups depending on whether they died or survived during the follow-up period.Mortality-related risk factors included age,gender,comorbidities,timing of operation,and type of fixation.T-test and Chi-squared test were used to analyze any significant differences between mortality and survival.Only the variables with a P ＜ 0.05 at the simple regression test were retested into a logistic multiple regression to screen risk factors for mortality after operation.Results Included in this study were 327 eligible patients with an average age of 78.7 years.They were 115 men (35.2％) and 212 women (64.8％).The total mortality till December 2017 was 40.1％ (there were 131 dead and 196 living cases).One-way analysis of variance showed that the risk factor related to mortality were stroke (P =0.016),dementia (P =0.005),heart failure (P =0.002),dysfunction of kidney (P =0.027) and type of anesthesia (P =0.015);logistic multiple regression analysis revealed that age (OR =1.092,P =0.000),stroke (OR =1.759,P =0.036),type of anesthesia (OR =6.730,P=0.035) and dysfunction of kidney (OR =5.624,P =0.026) were independent risk factors for long-term mortality.Conclusions Special attention should be paid on hip fracture patients with a high age,stroke and dysfunction of kidney,because their long-term mortality is high.For high risk patients with no obvious contraindications,proper anesthesia methods should be chosen which can lead to definite efficacy and little influence on the body.
ABSTRACT
<p><b>OBJECTIVE</b>To observe the effect difference of warming needling combined with decoction and ciloprost for arteriosclerosis obliterans (ASO) with stasis.</p><p><b>METHODS</b>A total of 96 ASO patients with stasis were randomly assigned into a combination group and a western medication group, 48 cases in each group. Anti-hypertension, glucose-lowering and lipid lowering therapies were applied in the two groups. Ciloprost was prescribed orally in the western medication group, twice a day, 100 mg a time. The main acupoints in the combination group were Sanyinjiao (SP 6), Yinlingquan (SP 9), Zusanli (ST 36), Guanyuan (CV 4), and Xuehai (SP 10), matched with Yanglingquan (GB 34) and Weizhong (BL 40). Warming needling was used at Sanyinjiao (SP 6), Zusanli (ST 36), Xuehai (SP 10) and Guanyuan (CV 4), 5 times a week, once a day, 20 min a time. At the same time, self-made decoction was applied in the combination group, 1 dose a day, twice a day. All the treatment was given for continuous 3 courses, 1 month as a course. The indexes were the symptom scores for cool limb skin, sour swelling, numbness, pain, abnormal complexion, ankle brachial index (ABI) and blood biochemical indexes, including fasting blood-glucose (FPG), triacylglycerol (TG), cholesterol total (TC), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), glutamic-pyruvic transaminase (ALT), glutamic-oxalacetic transaminase (AST), serum creatinine (Scr) and blood urea nitrogen (BUN). The adverse reactions were recorded. The clinical effect was evaluated. Two-month follow-up was carried out.</p><p><b>RESULTS</b>After treatment, the symptom scores for cool limb skin, sour swelling, numbness, pain, abnormal complexion and total score decreased in the two groups (all <0.05), with better results in the combination group (all <0.05).

ABSTRACT
Objective@#To evaluate the short-term and long-term outcomes after laparoscopic surgery compared with traditional laparotomy in cases of stage ⅠA2-ⅡA2 cervical cancer.@*Methods@#We conducted a retrospective study on the clinical data of 1 863 patients diagnosed as FIGO stages ⅠA2-ⅡA2 cervical cancer in 6 third-grade class-A hospitals in Guangxi province between January 2007 and May 2014. One thousand and seventy-one received laparoscopy, and 792 received laparotomy. T-test, U-test and χ2 test were used to compare the short-term and long-term outcomes. The short-term outcomes included surgical related outcomes and operative complications, and the long-term outcomes included quality of life (pelvic floor functions and sexual functions), survival and recurrence. Pelvic floor function and sexual function were assessed with the International Consultation on Incontinence Quesonnaire Female Lower Urinary tract(ICIQ-FLUTS) and the Female Sexual Function Inventory (FSFI), respectively. Survival rates were estimated by Kaplan-Meier analysis. The survival curves were compared with Log-rank test. Cox regression analysis was used to evaluaterisk factors for prognosis.@*Results@#(1)The short-term outcomes : There were significant difference in operative time([(257±69) vs(238±56)min], estimated blood loss[(358±314) vs(707±431)ml], anus exhausting time[(2.5±0.9) vs (2.9±0.8)d], preserved days of catheter[(15±7) vs(18±9)d], and post-operative length of stay[(19±16) vs (30±21)d] between the laparoscopic surgery group and the opensurgery group(P<0.05). There was no significant difference in lymph nodes yielded[(21±9) vs (21±11)], left parametrial width[(2.5±0.8) vs (2.7±0.7)cm], right parametrial width [(2.6±0.3) vs (2.7±0.2)cm], vaginal cuff length[(2.4±0.7) vs (2.2±0.7)cm] between the laparoscopic surgery group and the opensurgery group(P>0.05). The intra-operative complications occurred in 8.1%(87/1 071)in the laparoscopic surgery group and in 10.7%(85/792)in the open surgery group(P>0.05). However, the complications of vascular injury in the laparoscopic surgery group[2.6%(28/1 071)]was lower than that in the open surgery group[7.7%(61/792), P<0.001]. The laparoscopic surgery exhibited lower post- operative complication rate [33.8%(362/1 071)vs 40.2%(318/792), P<0.05] and poorer wound healing rate [0.7%(7/1 071)vs 4.0%(32/792), P<0.05]. (2)The long-term outcomes(Hierarchical analysis): The overall incontinence in ICIQ-FLUTS questionnaire in nerve-sparing laparoscopic group [28.4%(67/236)] was lower than that in the open surgery group [35.9%(71/198), P=0.004] . However, There was no significant difference in degree of incontinence between the two groups(P>0.05). The overall sexual dysfunction in FSFI questionnaire after 12 months of postoperative in the nerve-sparing laparoscopic group [47.0%(111/236)]was lower than that in the open surgery group [58.6%(116/198), P=0.001], and the six different dimension scores in the laparoscopic surgery group were higher than that in the open surgery group (P<0.05). The recurrence rate was 3.5%(35/1 007)in the laparoscopicsurgery group and 4.7%(35/740)in the open surgery group(P>0.05). The 5-year OS was 94.0% for the laparoscopic surgery group and 90.2% for the open surgery group(P>0.05), and the 5-year DFS was 93.9% for the laparoscopic surgery group and 89.1% for the open surgery group(P>0.05). (3) Prognostic fators: In univariate analysis, tumor dimension, clinical stage, deep stromal invasion, LVSI, and retroperitoneal lymph node metastasis signficantly affected 5-year OS and 5-year DFS(P<0.05); In multivariate analyses, LVSI, deep stromal invasion and LN metastasis were independent prognostic factors(P<0.05).@*Conclusions@#Laparoscopy can reduceestimated blood loss, accelerate postoperative recovery and improve the quality of life after surgery compared to laparotomy, and it ensures the same oncological results as open surgery. Laparoscopic approach is a safe and effective treatment for early-stage cervical cancer.
ABSTRACT
Objective To disccuss the antioxidative effects of sodium ozagrel(OZG) in myocardial ischemia in rats and illuminate its effect of decreasing oxidative damage.Methods Forty healthy Wistar rats were randomly devided into five groups:control,model,pretreatment,treatment and therapeutic alliance groups.OZG was used for 2 weeks in pretreatment group,then isoprenaline hydrochloride (ISO) was applied to make myocardial ischemia model.5 min after the establishment of model,OZG and OZG combined with glyceryl trinitrate(GT) were used in treatment group and therapeutic alliance group,respectively,ECG was recorded at the same time.1 h later,the activities of serum myocardial creatases(AST,LDH,CK),malonaldehyde(MDA) level and superoxide dismutase(SOD) activity were detected.Results ECG:When the model was successfully set up,ST segment in every group all raised≥0.1 mV,the minimum value of raise was in pretreatment group.When the model was succeeded 5 min later,ST segment in model group slightly decreased but still ≥0.1 mV and it was significant in pretreatment group.In treatment and therapeutic alliance groups,compared with model succeeding'ST segment,ST segment decreased significantly at 5 min later(P
