Objective:To observe the clinical efficacy of posterior vertebral column resection (PVCR) combined with double row nanomimetic bone column implantation and internal fixation in the treatment of stage Ⅲ Kümmell's disease plus kyphosis.Methods:A retrospective study was conducted to analyze the clinical data of the 12 patients with stage Ⅲ Kümmell's disease plus kyphosis who had been admitted to Department of Spine Surgery, Zhengzhou Orthopedic Hospital from March 2017 to September 2023. There were 2 males and 10 females, with an age of (63.4±6.4) years and a disease duration of (8.6±5.1) months. The injured segment was T 11 in 1 patient, T 12 in 5 ones, and L 1 in 6 ones. The preoperative spinal nerve injury was graded according to American Spinal Injury Association (ASIA): grade D in 5 cases and grade E in 7 cases. All the patients were treated with PVCR combined with double row nanomimetic bone column implantation and internal fixation. The operation time, intraoperative blood loss, shortening rate of the osteotomy area, complications during follow-up, and spinal nerve recovery at the last follow-up were recorded. The visual analogue scale (VAS) pain scores, Oswestry Disability Indexes (ODIs), and local kyphosis Cobb angles were compared between pre-surgery, 2 weeks after surgery, and the last follow-up. Results:Incisions in all the 12 patients healed at the primary stage. Their operation duration was (268.4±26.5) min, intraoperative blood loss (994.9±180.4) mL, shortening rate of the osteotomy area 3.94%±7.58%, and follow-up duration (24.1±13.5) months. At 2 weeks after surgery and the last follow-up, the VAS pain scores [(3.08±0.79) points and (1.17±0.58) points] and ODIs (27.59%±6.10% and 16.67%±2.22%) were significantly lower than those before surgery [(8.08±0.79) points and 73.14%±5.64%], and the values at the last follow-up were further significantly lower than those at 2 weeks after surgery (all P<0.05). There was no statistically significant difference in the Cobb angle at the last follow-up (5.29°±1.30°) compared with 2 weeks after surgery (4.74°±1.31°) ( P>0.05), but there was a statistically significant difference compared with the preoperative value (49.41°±4.40°) ( P<0.05). At the last follow-up, the ASIA grading in all the 12 patients recovered to grade E, with good bone healing at the fixation segment. No screw loosening or fracture was found. Two patients had a biomimetic bone column sinking of 3.5 and 4.0 mm, respectively, but their Marchi's grading was still 0. During the follow-up period, one patient developed proximal junctional kyphosis, and one patient developed an osteoporotic fracture of the proximal vertebral body at the fixed level. Conclusions:In the treatment of stage Ⅲ Kümmell's disease plus kyphosis, PVCR combined with double row nanomimetic bone column implantation and internal fixation can significantly correct the kyphosis and improve clinical symptoms, leading to good clinical efficacy.

ObjectiveTo investigate the value of aspartate aminotransferase-to-platelet ratio index （APRI） and platelet-albumin-bilirubin （PALBI） score in predicting the risk of esophagogastric variceal bleeding in patients with liver cirrhosis. MethodsA total of 119 patients with liver cirrhosis who were admitted to The First Affiliated Hospital of Soochow University from May 2021 and June 2022 were enrolled， and clinical data， routine blood test results， serum biochemistry， and coagulation test results were collected from all patients. According to the presence or absence of esophagogastric variceal bleeding， the patients were divided into non-bleeding group with 59 patients and bleeding group with 60 patients， and a comparative analysis was performed for the two groups. The independent samples t-test was used for comparison of normally distributed continuous data between two groups， and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups； the chi-squared test or the Fisher’s exact test was used for comparison of categorical data between groups. The multivariate Logistic regression analysis was used to identify the independent risk factors for esophagogastric variceal bleeding in patients with liver cirrhosis and establish a nomogram predictive model. ResultsThe male patients accounted for 75.00% in the bleeding group and 40.68% in the non-bleeding group， and there was a significant difference in sex composition between the two groups （χ²=14.384， P<0.001）. Chronic hepatitis B was the main etiology in both the bleeding group and the non-bleeding group （53.33% vs 38.98%）， and there was no significant difference in composition ratio between the two groups （χ²=2.464， P=0.116）. Compared with the non-bleeding group， the bleeding group had a significantly higher activity of AT-IIIA （t=3.329， P=0.001） and significantly lower levels of PLT， TBil， Ca， TC， and TT （all P<0.05）. There were significant differences in APRI and PALBI between the two groups （χ²=6.175 and 19.532， both P<0.05）. The binary logistic regression analysis showed that APRI （odds ratio ［OR］=0.309， 95% confidence interval ［CI］： 0.109‍ ‍—‍ ‍0.881， P=0.028）， PALBI （OR=7.667， 95%CI： 2.005‍ ‍—‍ ‍29.327， P=0.003）， Ca （OR=0.001， 95%CI： 0.000‍ ‍—‍ ‍0.141， P=0.007）， TC （OR=0.469， 95%CI： 0.226‍ ‍—‍ ‍0.973， P=0.042）， and TT （OR=0.599， 95%CI： 0.433‍ ‍—‍ ‍0.830， P=0.002） were independent influencing factors for esophagogastric variceal bleeding in liver cirrhosis. A nomogram model was established based on the above factors and had an index of concordance of 0.899 and a well-fitted calibration curve. ConclusionAPRI and PALBI have a good value in predicting esophagogastric variceal bleeding in patients with liver cirrhosis， and the nomogram model established based on this study can predict the incidence rate of esophagogastric variceal bleeding in patients with liver cirrhosis.

PURPOSE: Rapid decompressive craniectomy (DC) was the most effective method for the treatment of hypertensive intracerebral hemorrhage (HICH) with cerebral hernia, but the mortality and disability rate is still high. We suspected that hematoma puncture drainage (PD) + DC may improve the therapeutic effect and thus compared the combined surgery with DC alone. METHODS: From December 2013 to July 2019, patients with HICH from Linzhi, Tibet and Honghe, Yunnan Province were retrospectively analyzed. The selection criteria were as follows: (1) altitude ≥1500 m; (2) HICH patients with cerebral hernia; (3) Glascow coma scale score of 4-8 and time from onset to admission ≤3 h; (4) good liver and kidney function; and (5) complete case data. The included patients were divided into DC group and PD + DC group. The patients were followed up for 6 months. The outcome was assessed by Glasgow outcome scale (GOS) score, Kaplan-Meier survival curve and correlation between time from admission to operation and prognosis. A good outcome was defined as independent (GOS score, 4-5) and poor outcome defined as dependent (GOS score, 3-1). All data analyses were performed using SPSS 19, and comparison between two groups was conducted using separate t-tests or Chi-square tests. RESULTS: A total of 65 patients was included. The age ranged 34-90 years (mean, 63.00 ± 14.04 years). Among them, 31 patients had the operation of PD + DC, whereas 34 patients underwent DC. The two groups had no significant difference in the basic characteristics. After 6 months of follow-up, in the PD + DC group there were 8 death, 4 vegetative state, 4 severe disability (GOS score 1-3, poor outcome 51.6 %); 8 moderate disability, and 7 good recovery (GOS score 4-5, good outcome 48.4 %); while in the DC group the result was 15 death, 6 vegetative state, 5 severe disability (poor outcome 76.5 %), 4 moderate disability and 4 good recovery (good outcome 23.5 %). The GOS score and good outcome were significantly less in DC group than in PD + DC group (Z = -1.993, p = 0.046; χ CONCLUSION PD + DC treatment can improve the good outcomes better than DC treatment for HICH with cerebral hernia at a high altitude.

BACKGROUNDAn zidovudine (AZT)-substitution regimen containing 24-week stavudine (d4T) followed by long-term AZT for HIV therapy is potential to trade off short-term AZT-related anemia and long-term risks associated with d4T in resource-limited settings. However, evidence is scarce. This study aims to assess the efficacy and safety of AZT-substitution regimen, aiming to find a regimen with better efficacy, less adverse events, and more affordability in resource-limited settings.

METHODSThis prospective, multicenter study enrolled 499 (190 on d4T regimen, 172 on AZT regimen, and 137 on AZT-substitution regimen) HIV-1-infected subjects who initiated combined antiretroviral therapy and attended follow-up visits over 96 weeks from 2009 to 2011. Lamivudine (3TC) and either nevirapine (NVP) or efavirenz (EFV) were the other two drugs in the antiretroviral regimens. Virologic and immunologic responses and adverse events were monitored at baseline and at weeks 4, 12, 24, 36, 48, 60, 72, 84, and 96.

RESULTSIn terms of hematological adverse effects, AZT-substitution group had similar safety profiles to d4T group and was superior to AZT group. In comparison with AZT-substitution group, AZT group was associated with higher risk of developing anemia (adjusted hazard ratio (aHR) for anemia ≥ grade II, 8.44, 95% CI 1.81-39.46) and neutropenia (aHR for neutropenia ≥ grade II, 1.86, 95% CI 1.19-2.93). The prevalence of lipodystrophy in d4T group was 19.5%, while that in AZT-substitution group was zero. As to antiretroviral efficacy, these three groups showed no differences.

CONCLUSIONAZT-substitution regimen provides a relatively safe and effective first-line antiretroviral strategy in resource-limited settings.

Two sample pretreatment methods of pesticide residues in Panax notoginseng of Chinese traditional medicine were developed. For Method I, the residues were extracted from homogenized tissue with n-hexane-dichloromethane (6:4) by means of ultrasonication, the crude extract was purified by an Envi-carb/NH2 solid-phase extraction (SPE) column. For Method II, matrix solid-phase dispersion (MSPD) technique was used for extracting and cleaning up. The eluates were concentrated by rotary evaporation, and then were redissolved in dichloromethane prior to GC-MS determination. The determination was performed in selected ion monitoring (SIM) mode with the external calibration for quantitative analysis. Under the optimal conditions, the results indicated that the methods are easier and faster, the recoveries of method I for the spiked standards at concentration of 0.01, 0.5, and 2.0 mg x kg(-1) were 81.90%-102.10% with the relative standard deviations (RSDs) of 3.60%-7.10%. The recoveries of method II were 96.26%-104.20% with the RSDs of 3.52%-7.94%. The detection limits (S/N) for residues of pesticides were in the range of 0.48-1.34 ng x g(-1). The results indicated that these multiresidue analysis methods can meet the requirements for determination of residue pesticides and can be appropriate for trace analysis of residue pesticides in Panax notoginseng.
