Objective To compare the curative effects of intertrochantefie fractures in aged by two operative methods. Methods 85 cases of elderly patients suffered from intertrechanteric fractures were retrospectively ana-lyzed. Out of the 85 cases,45 cases were treated with dynamic hip screw(DHS) and 40 cases were fixed with Gamma nails. The curative effects and complications were compared simultaneously. Results The total excellent rate was 83.5% in 85 patients,the rates of DHS and Gamma nails group were 77. 8% and 90% (X2 = 2. 84, P 0. 05), re-spectively. The operative time (66. 4 ± 19. 4)min in DHS group were less than the Gamma nail group (875 ± 25.5) rain (t=2. 451 ,P < 0. 05), but the length of surgical incision (19. 6± 5. 1)cm greater than the Gamma nail group (10. 3 ± 4. 7) cm(t = 2. 501, P < 0. 05). The complications of DHS group (11.1%) were significanfly higher than that of Gamma nail group(2. 5%) (X2 =3.94,P<0. 05). Conclusion As long as the physical condition can toler-ate,surgery recommend the use of DHS and Gamma nail surgical techniques in aged patients with intertrechanteric fractures.

Objective To investigate the relationship between perioperative allogeneic blood transfusion and postoperative infection. Methods The records of 213 consecutive patients undergoing elective radical resection of colorectal cancer at the first Affiliated Hospital of Zhongshan University from January 1st, 2001 to December 31st, 2001 were reviewed. The association of allogeneic blood transfusion with postoperative infection was analyzed by logistic regression. Correction for multiple analysis were made to eliminate the effects of confounding factors. Results Among the patients who received transfusion the incidence of postoperative infection was higher than that among those who received no allogeneic blood ( P

Objective To discuss the effects of two different fluid resuscitation methods on early resuscitation and clinical prognosis in traumatic shock patients. Methods One hundred and twenty-six patients were treated with two different fluid resuscitation methods in traumatic shock (TS). These patients were randomly divided into 2 groups according to the strategy: the conventional resuscitation group (conventional group, 66 cases), the hypertouic saline solution resuscitation group (hypertonic saline group, 60 cases).The heart rate, blood pressure, breath, blood Na+ ,blood Cl-, the original thrombin time before and after the resuscitation and the syndrome were observed and analyzed. Results The input in the conventional group was (3000±500) mL, in the hypertonic saline group was (2000±200) mL. The difference of the input between the two groups was significant (P < 0. 05). The difference of the heart rate, blood pressure,breath, and the original thrombin time before and after half hour to one hour of the resuscitation in the two groups was not significant (P<0.05). The difference of the blood NA+, blood CL- and the original thrombin time before and after half hour to one hour of the resuscitation in the two groups was not significant (P <0. 05). The difference of the ARDS incidence, MODS incidence, cure rate and death rate from onset of the diseases to hospitalization in the two groups was significant (P <0. 05). Conclusions The fluid resuscitation strategy with hypertonic saline in early period of traumatic shock is efficient, which can work well with low fluid quantity, enhance blood pressure in short time, improve breath quality, save time for the operation of the primary injury, heighten the resuscitation rate, decrease the syndrome incidences and the death rate. The early fluid resuscitation strategy is worthy of clinical application and popularization.

Objective To study curative effect of core decompression and autologous bone marrow stem cell transplantation combined with traditional Chinese medicine in the treatment of early femoral head necrosis (ANFH).Methods 30 patients with femoral head necrosis treated by different methods were divided into 3 groups: core decompression A group) 10 cases(12 hips) ;core decompression pus stem cells transplantation(B group) 10 cases(13 hips) ;core decompression pus stem cells transplantation combined with traditional Chinese medicine(C group) 10 ca-ses( 10 hips) ;The X-ray 、CT MRI、Harris score( HHS) .curative effect were observed.Results The phase of Ⅰ,Ⅱ,Ⅲ,in 3 groups didn't appear deformation and collapse at 3,6,12 months;The score of Harris after 12 months 93 points were higher than that preoperatively 57.5 points(χ 2= 5.81 ,P<0.05) ;The signal ratio of femoral head volume in MRI was 42% before treatment,disappearance of femoral head necrosis after treatment;Total curative effect of B,C group,werehighter than that Agroup(χ2 =3.81,χ2 =3.98,P<0.05).Conclusion The operative treatment of ANFH with core decompression and stem cells transplantation combined with traditional Chinese medicine had the advantage of minimal damage,simplicity,accuracy,and effectiveness.

Objective To study the characteristics and therapeutic effect of femoral neck fractures in young adults by many treatment methods. Methods 32 cases with femoral neck fractures in young adults 21-50 years. Using of tube decompression of the femoral head involvement, fracture of drug injection, intravenous drip and so many ways of delivery, to regular observe their fracture healing and clinical efficacy. Results All 32 cases with femoral neck fracture postoperative follow-up 5-9 months to obtain bone healing;Follow-up to 1 year of hip joint function was basically normal,non-femoral head necrosis. Follow-up to 3 years,32 cases in 26 cases of excellent,good in 5 and poor in example 1. Example 1 due to poor weight -bearing walking premature and older (50 years) appear avascular necrosis of femoral head,the total hip arthroplasty. Conclusion The joint methods have an exact effect in patirnts with femoral neck fracture.The advantages were easy to operate,less trauma and fewer complications,fast recovery ,easy to promote.

Objective:To evaluate the value of platelet to lymphocyte ratio (PLR) and neutrophil to lymphocyte ratio (NLR) in predicting short-term prognosis of acute severe carbon monoxide poisoning.Methods:Clinical data of 180 patients with acute severe carbon monoxide poisoning admitted to Hanzhong Central Hospital from October 2021 to May 2023 were retrospectively analyzed. According to the prognosis of the patients within 6 months, they were divided into poor prognosis group ( n=37) and good prognosis group ( n=143). The baseline data and laboratory indicators of the two groups were compared, and the risk factors of short-term poor prognosis in acute severe carbon monoxide poisoning patients were analyzed by multivariate logistic regression. The value of neutrophils (NEU), platelets (PLT), lymphocytes (LYM), PLR and NLR in predicting short term poor prognosis in patients with acute severe carbon monoxide poisoning was analyzed by receiver operating characteristic (ROC) curve. Results:The proportion of ≥60 years old, stroke history, exposure time >8 h and the levels of NEU, PLR and NLR in the poor prognosis group were higher than those in the good prognosis group, while the PLT and LYM were lower than those in the good prognosis group (all P<0.05). Multivariate logistic regression analysis confirmed that ≥60 years old, stroke history, exposure time >8 h, PLT, LYM, NEU, PLR, NLR levels were the risk factors for short-term poor prognosis in acute severe carbon monoxide poisoning patients (all P<0.05). According to ROC curve analysis, the areas under ROC curve of PLT, LYM, NEU, PLR and NLR to predict the short-term prognosis of acute severe carbon monoxide poisoning patients were 0.684, 0.702, 0.720, 0.889 and 0.801, respectively. Conclusions:Age, stroke history, exposure time, PLT, LYM, NEU, PLR and NLR levels are all factors affecting the short-term poor prognosis of patients with acute severe carbon monoxide poisoning. Increasing PLR and NLR levels will increase the risk of short-term poor prognosis of patients with acute severe carbon monoxide poisoning.
