Objective To investigate the diagnostic value ofbiomarkers in cerebrospinal fluid in differentiating meningeal carcinomatosis (MC) and tubercular meningitis (TBM).Methods The clinical features and cerebrospinal fluid (CSF) test results of 34 patients with MC and 44 patients with TBM,admitted to our hospital from January 1994 to August 2014,were retrospectively analyzed and compared.Results The main clinical manifestations of MC included headache and bowel and bladder dysfunction,and those of TBM were fever and headache.The cell population of MC and TBM patients increased and the number of leucocyte of TBM patients was significantly larger than that of MC patients (P＜0.05);the CSF of all the patients presented with decreased levels of glucose and chloride,and increased protein level,and higher protein in MC patients was noted than that in TBM patients (P＜0.05).The biomarkers in CSF of MC and TBM patients increased to varying degrees,and the biomarkers,including carcinoembryonic antigen (CEA),cancer antigen (CA) 125,CA 199,CA 153 and CYFRA21-1,in MC group were significantly higher than those in TBM group (P＜0.05).The neuron-specific enolase level in the TBM patients of Ⅲ grade was significantly higher than that in the MC patients (P＜ 0.05).Conclusion The detections of tumor biomarkers in cerebrospinal fluid is a tool in differentiating MC and all stages of TBM,especially with the combined detections of CEA,CA125,CA199 and CYFRA21-1.

This study was aimed to observe the curative effect and safety of Danzhi Jiangtang Capsule ( DJC ) combined with atorvastatin on carotid artery intima-media thickness (IMT) in diabetes patients without hyper-tension . A total of 196 diabetes patients without hypertension with incrassate carotid artery IMT were randomly divided into the control group ( 98 cases ) and the treatment group ( 98 cases ) . The conventional diabetes thera-py was given to both groups . The atorvastatin of 20 mg/night was given to the control group . And the atorvas-tatin 20 mg/night added with DJC 9 . 0 g/night were given to the treatment group . The treatment course was
12 months . Carotid artery IMT , carotid atherosclerotic plaque area , FPG , FIns , HOMA-IR , HbA1c , blood lipids , hepatorenal function and etc . were examined before and after the treatment respectively . The results showed that there was a significant positive correlation between carotid artery IMT and FIns , HOMA-IR , HbAlc , LDL-C . After 12-month treatment , the total effectiveness is 85 . 87% in the treatment group . And there was significant difference compared with the control group ( P < 0 . 05 ) . The levels of FPG , FIns , HOMA-IR , HbAlc of the treatment group had no difference compared with the control group . Compared with the control group, TC and LDL-C of the treatment group was obviously decreased (P < 0.05). And HDL-C was significantly increased ( P < 0 . 05 ) . The carotid artery IMT of the treatment group decreased from ( 0 . 11 ±0 . 01 ) cm to ( 0 . 08 ± 0 . 01 ) cm . And compared with the control group , there was statistical significance ( P <0 . 05 ) . The carotid atherosclerotic plaque area of 58 cases in the treatment group decreased from ( 0 . 37 ±0.56) cm2 to (0.21 ± 0.25) cm2. However, there was no statistical significance compared to the control group. There were 5 adverse events in the control group and 9 adverse events in the treatment group . And there was no difference between two groups. It was concluded that DJC combined with atorvastatin can regulate lipid metabolism and reduce carotid artery IMT .

Objective:To study the efficacy of closed reduction with a self-developed T-frame plus robotic navigation in the treatment of supracondylar humeral fractures of Gartland type Ⅲ in children.Methods:A retrospective study was conducted to analyze the data of 67 children with supracondylar fracture of Gartland type Ⅲ who had undergone surgery at The Fifth Hospital of Harbin from January 2023 to March 2024. There were 35 males and 32 females with an age of (5.6±1.2) years. The children were divided into 2 groups according to different surgical methods. The control group (33 cases) was treated by closed reduction and internal fixation with percutaneous K-wire and the study group (34 cases) by closed reduction with a self-developed T-frame plus robotic navigation for internal fixation with percutaneous K-wire. The operation time, anatomical reduction, intraoperative fluoroscopy frequency, intraoperative needle adjustment, Flynn score at the last follow-up and complications were compared between the 2 groups.Results:There was no significant difference in the preoperative general data between the 2 groups, indicating comparability ( P>0.05). All children were followed up for (6.3±2.5) months after surgery. There were no significant differences in operation time, Flynn score at the last follow-up or incidence of complications between the study and the control groups ( P>0.05). The rate of anatomical reduction in the study group (97.1%, 33/34) was significantly higher than that in the control group (54.5%, 18/33), and the intraoperative fluoroscopy frequency [(11.6±2.5) times] and needle adjustment (5.6±1.2) times in the study group were significantly lower than those in the control group [(37.2±2.1) times and (28.7±3.9) times] ( P<0.05). Conclusions:In the treatment of supracondylar humeral fractures of Gartland type Ⅲ in children, our self-developed T-frame can play a good role in fracture reduction and temporary fixation, avoiding iatrogenic secondary injuries caused by freguent reduction and adjustment of needle threading in the course of robotic navigation.
