BACKGROUND:Studies have shown that malnutrition was associated with death of elder people after fracture of hip, but there were no above-mentioned reports in China.
OBJECTIVE: To retrospectively analyze the relationship of blood albumin, total lymphocyte count and hemoglobin levels to prognosis when elder patients with fracture of hip were on admission.
METHODS:130 elderly patients with hip fractures aged ≥ 70 years were included underwent either total hip arthroplasty or bipolar arthroplasty. Admission serum albumin, total lymphocytecount and hemoglobin levels were recorded. The patients were fol owed up for 1 year or til the death. Survival data were available in 92 patients. Rates of survival were calculated by the Kaplan-Meier method and the Log-Rank test. Cox proportional hazard regression model received prognostic multivariate analysis.
RESULTS AND CONCLUSION:Of the 92 patients, albumin<35 g/L in 20 cases (22%), total lymphocyte count<1.5×106/L in 67 cases (73%), and hemoglobin<120 g/L in 56 cases (61%). Kaplan-Meier method showed that the survival rate of patients with normal albumin (≥ 35 g/L) was significantly higher than those with reduced albumin (<35 g/L) (P<0.01). No significant difference was detected in the survival rate of patients with normal total lymphocyte count (≥ 1.5×106/L) and reduced total lymphocyte count (<1.5×106/L) (P>0.05). The survival rate of patients with normal hemoglobin (≥ 120 g/L) was significantly higher than those with decreased hemoglobin (<120 g/L) (P <0.05). Cox multivariate analysis displayed that albumin decrease is an independent prognostic factor for death of patients with hip fracture. Results indicated that the prognosis of elder patients with hip fracture was strongly associated with their nutritional conditions. Albumin and hemoglobin levels at admission can be considered as important indexes for judging patient’s prognosis.

Aim To study the effect of 3-pyridin-3-yl-4-[(4-hydroxy-3-methoxy-benzylidene)amino]-5-me-thylsulfanyl-4H-[1,2,4] triazole (LH-37) on induction of differentiation and apoptosis of hepatocarcinoma BEL-7402 cells. Methods BEL-7402 cells were cultured in RPMI 1640 and treated by LH-37 at different doses. The proliferation of the cells and the inhibition effect of LH-37 on the cell proliferation were examined by MTT assay. The reverse transcriptase-polymerase chain reaction (RT-PCR) was used to detect the changes of alpha fetoprotein(?-FP)mRNA and albumin(Alb). The concentration of ?-FP in the cells was detected by ELISA assay. Cell morphology was observed by fluorescence microscope techniques. The protein expressions of active caspase-3 in BEL-7402 cells were observed by immunohistochemical staining. Western blot was used to assay caspase-3 and caspase-9. Colorimetric method was used to assay activity of superoxide dismutase (SOD) and catalase (CAT). The apoptotic cells were assayed by flow cytometry (FCM) with annexin V-FITC conjugated and propidium iodide (PI) staining. Results The cell proliferation was inhibited by LH-37 at 10 ?mol?L-1~1 mmol?L-1 in dose dependent manners. After treated with 10 ?mol?L-1 or 1.0 ?mol?L-1 LH-37, the mRNA and protein expression of ?-FP were significantly reduced but mRNA expression of Alb was significantly increased. Treatment of BEL-7402 cells with different LH-37 concentrations for 48 hours increased the percentage of active caspase-3 positive cells and protein expression of caspase-3 and caspase-9. More apoptosis features of cells were observed in LH-37 ( 100 ?mol?L-1) treatment groups than in control group. LH-37 markedly promoted the viability of SOD and decreased CAT in BEL-7402 cells. Counclusion LH-37 might inhibit proliferation and induce differentiation and apoptosis of human hepatocarcinoma BEL-7402 cells, which might be related to the cytotoxicity of the intracellular hydrogen peroxide (H2O2).

Objective: On the basis of typical cases, the objective of this study is to assess the service quality of primary healthcare institutions under the vertically integrated model from the perspective of demanding side.Methods: The vertical model between Renhe Hospital and Lixian Township Health Center was selected as the case study.Quantitative data were collected by exit review using Primary health-Care quality service Assessment Tool (PCAT)-Chinese version from the patients seeking services in Lixian.Quantitative data were analyzed by descriptive statistics and multiple linear regression equations while qualitative data were analyzed by thematic framework analysis.Results: Under the vertical model, the PCAT total score was 20.09.The scores on the first diagnosis, continuity of care, and comprehensiveness of care and coordination of care were 6.59, 3.27, 4.58 and 5.62 respectively.The scores on the three dimensional extensions, family-centered, community-oriented, medical culture were 3.07, 1.86 and 2.67 respectively.The difference was significant for the PCAT total score between a number of visits and the length of waiting time for services in Lixian.Conclusions: Under the vertical model, primary healthcare institutions did better in the first diagnosis while weaker in continuity and the three dimensional extensions.With the development of the integration, the primary healthcare institutions need to strengthen the continuity and downward referral in the future.Future researches and follow-up, analysis is needed to track the impact of the vertically integrated model.

Objective To investigate the value of endoscopic carbon nanoparticles labeling technique assisted in situ resection after neoadjuvant chemoradiotherapy(nCRT)for middle and low locally advanced rectal cancer(LARC).Methods From January 2020 to January 2023,46 cases of middle or low LARC were selected for endoscopic injection of carbon nanoparticles suspension to label the lower edge of the tumor before nCRT,and laparoscopic anterior resection of the rectum was performed after nCRT.The main observations were the visualization of carbon nanoparticles marker during the operation,the length of each area(primary tumor area,tumor regression scar,distal resection margin,and regression area of lower edge of tumor)of surgical specimens and the positive rate of distal resection margins.Results The median interval between injection of carbon nanoparticles suspension and surgery was 105(77-182)d in the46 cases.Carbon nanoparticles remnants were observed on the rectal mucosal surface in all the patients after nCRT by endoscopy.During laparoscopic anterior rectal resection surgeries,carbon nanoparticles marker exposure on the surface of the rectal intrinsic fascia observed in 41 cases(89.1%),of which38 cases were judged as good exposure(the width of marker area≤1.5 cm,which assisted the operator accurately determining the distal surgical margins)and 3 cases were judged as inferior exposure(a larger range of black staining whereas in situ resection of the tumor still achievable).In another 5 cases,the carbon nanoparticles marker could not be observed and were judged as exposure failure.Intraoperative cryopathology showed that all distal resection margins were negative.Measurement of 30 surgical specimens with identifiable primary tumor area showed that the length of resected intestinal canal was 17.9(10.1-25.7)cm,the diameter of primary tumor area was(4.3±0.8)cm,the diameter of scar after tumor regression was 2.5(0.8-4.8)cm,and the length of regression of tumor lower margin was 1.0(0-2.9)cm.The length of distal resection margins in middle rectal cancer(n =17)was3.4(1.5-4.3)cm and in low rectal cancer(n =13)was1.6(0.5-2.8)cm.Conclusion Application of carbon nanoparticles labeling technology before nCRT for rectal cancer can effectively mark the lower margin of the primary tumor in a long time and assist surgeons to precisely remove the primary tumor area.
