OBJECTIVE: To investigate the efficacy of posterior axillary approach internal fixation for Ideberg Ⅰa andⅡ glenoid fractures. METHODS: From December 2018 to September 2021, 9 patients with lower part of glenoid fractures were treated by posterior axillary approach, including 3 males and 6 females, aged from 50 to 78 years old. All the fractures were closed fractures. According to Ideberg type of scapular glenoid fracture was type Ⅰa in 6 cases and type Ⅱ in 3 cases. AP and lateral X-ray films of scapula were taken at 6, 12 weeks and 6 and 12 months postoperatively. Constant-Murley and disabilities of the arm shoulder and hand (DASH), and other complications were recorded at the latest follow-up. RESULTS: Nine patients were followed up, ranged from 6 to 15 months. And bone healing was achieved in all 9 patients at the final follow-up, the healing time 3 to 6 months, Constant-Murley score at the final follow-up ranged from 55 to 96, and DASH score ranged from 3.33 to 33.33. Both of them were better than preoperative. CONCLUSION The posterior axillary approach internal fixation for Ideberg Ⅰa and Ideberg Ⅱ Glenoid fractures scapular fracture is satisfactory and worthy of clinical application.

OBJECTIVE Cerebral ischemia or ischemic stroke is due to insufficient blood supply to the brain, which causes hypoxia or ischemia in some areas. This work aimed to quantify the minerals and heavy metals in Qishiwei Zhenzhu pill in vivo and in vitro, analyze its effect on the types and abundance of intestinal flora, and study its mechanism on inflammation and apoptosis pathways as a treatment for cerebral ischemia. METHODS Microwave digestion and induc?tively coupled plasma mass spectrometry (ICP-MS) were used to determine the minerals and heavy metals in 10 batches of Qishiwei Zhenzhu pill in vitro. With the use of the middle cerebral artery obstruction (MCAO) model, ICP-MS was applied to determine the content of minerals and heavy metals in hepatic portal vein blood, abdominal aortic blood, brain, liver, kidney, hair, urine and feces at different time periods. On this model, the ileum, cecum, and colon tissues were tested for intestinal pathology, and 16S rRNA was used for sequencing. Species taxonomy, α diversity, and spe?cies microbial composition and structure analysis were also performed. Polymerase chain reaction and Western blotting were employed to determine the mRNA and protein expression of p38 MAPK, caspase-3, IL-1β and TNF-α in the isch?emic brain tissues of rats. RESULTS The average content of heavy metals in the 10 batches of Qishiwei Zhenzhu pill samples is in the descending order Hg>Cu>Pb. Significant differences in the metal elements are found among Qishiwei Zhenzhu pill from different manufacturers but not among the different batches of the same manufacturer. An extremely low content of heavy metals are absorbed into the blood or accumulated in the brain, liver, kidney, and other tissues. Stool is the main excretion route of minerals and heavy metals from Qishiwei Zhenzhu pill. This medicine helps repair the intestinal mucosa in MCAO rats. At the phylum level, it can regulate the abundance of Firmicutes and Proteobacteria in the intestinal flora of rats with cerebral ischemia. At the genus level, it can adjust the abundance of Escherichia Shigella. At the species level, it can adjust the abundance of Lactobacillus yoelii and Lactobacillus reuteri. Cluster classification results show that Qishiwei Zhenzhu pill can improve the intestinal flora of rats with cerebral ischemia, reduce the mRNA and protein expression of caspase-3 and IL-1βin rat brain tissues, and have a tendency to decrease the mRNA expres?sion of p38 MAPK and TNF-α. CONCLUSION Quantifying the minerals and heavy metals in Qishiwei Zhenzhu pill in vivo and in vitro will help improve their quality standards. Minerals and heavy metals are mainly excreted in feces, accumu?late in extremely low levels in various tissues, and do not damage the intestinal mucosa. The effective material basis of Qishiwei Zhenzhu pill in treating cerebral ischemia may be related to their Li, Cr, and Cd elements. These pills can improve the environment of intestinal flora, and their mechanism of treatment for cerebral ischemia may be related to the down-regulation of IL-1βinflammatory factor and inhibition of cell apoptosis.

This study aimed to examine the clinical and radiographic outcomes of primary total knee arthroplasy (TKA) with use of NexGen® Legacy® Constrained Condylar Knee (CCK) prosthesis for severe knee deformity. Clinical data of 46 patients (48 knees in total, aged 61 years on average) with severe knee deformity who underwent TKA with NexGen® Legacy® CCK prosthesis between December 2007 and February 2012 were retrospectively analyzed. There were 34 knees with severe valgus with incompetent medial collateral ligament, 11 knees with severe flexion contracture with inability to achieve knee balancing in flexion and extension by posterior soft tissue release, 2 knees with Charcot arthritis with severe varus and bone loss, and 1 with traumatic osteoarthritis with severe varus and ligamentous instability. The mean duration of follow-up was 71 months (range 40-90 months). The New Knee Society scoring (NKSS) system and the Hospital for Special Surgery (HSS) score were used to evaluate the functional and clinical outcomes. Visual Analogue Scale (VAS) was used for pain measurement and Knee Society criteria for evaluation of radiological images. The results showed that, in the total 48 knees, 1 case of loosening due to short-stem tibial component at 3 months post-operatively underwent revision. The 6-year prosthesis survival rate in this cohort was 97.9%. There was no component infection occurring within 6 years. Significant post-operative improvements were found in NKSS and HSS scores. Patient satisfaction was significantly increased. Pain score was decreased significantly. Total functional score was improved from 31.46±11.43 to 86.42±8.87, range of motion (ROM) from 42.42°±23.57° to 95.31°±23.45° and the flexion contracture from 5.31°±7.87° to 0.92°±1.80°. Preoperative radiographic study showed excessive valgus (≥7°) in 37 knees, and varus deformity in 3 knees. Post-operative femorotibial alignment was valgus 3.88°±1.76° in 48 knees. Antero/posterior (A/P) view of X-ray films showed 4 radiolucent lines (RLL) in 48 tibial components. It was concluded that TKA with CCK is effective for the treatment of the severe unstable knee that cannot be balanced by soft tissue.

This study aims to investigate the effects of fibroblast growth factor 21 (FGF-21) on learning and memory abilities and antioxidant capacity of D-galactose-induced aging mice. Kunming mice (37.1 +/- 0.62) g were randomly divided into normal control group, model group and FGF-21 high, medium and low dose groups (n = 8). Each group was injected in cervical part subcutaneously with D-galactose 180 mg x kg(-1) x d(-1) once a day for 8 weeks. At the same time, FGF-21-treated mice were administered with FGF-21 by giving subcutaneous injection in cervical part at the daily doses of 5, 2 and 1 mg x kg(-1) x d(-1). The normal control group was given with normal saline by subcutaneous injection in cervical part. At seventh week of the experiment, the learning and memory abilities of mice were determined by water maze and jumping stand tests. At the end of the experiment, the mice were sacrificed and the cells damage of hippocampus was observed by HE staining in each group. Reactive oxygen species (ROS), malondialdehyde (MDA), superoxide dismutase (SOD), glutathione peroxidase (GPx), catalase (CAT) and total antioxidant capacity (T-AOC) in the brain of mice were determined. The results showed that different doses of FGF-21 could reduce the time reaching the end (P < 0.01 or P < 0.05) and the number of touching blind side (P < 0.01 or P < 0.05) in the water maze comparing with the model group. It could also prolong the latency time (P < 0.05) and decrease the number of errors (P < 0.01 or P < 0.05) in the step down test. The result of HE staining showed that FGF-21 could significantly reduce brain cell damage in the hippocampus. The ROS and MDA levels of three different doses FGF-21 treatment group reduced significantly than that of the model group [(5.58 +/- 1.07), (7.78 +/- 1.92), (9.03 +/- 1.77) vs (12.75 +/- 2.02) pmol (DCF) x min(-1) x mg(-1), P < 0.01 or P < 0.05], [(2.92 +/- 0.71), (4.21 +/- 0.81), (4.41 +/- 0.97) vs (5.62 +/- 0.63) nmol x mg(-1) (protein), P < 0.01]. Comparing with the model group, the activities of SOD, GPx, CAT and T-AOC of the three different doses FGF-21 treatment groups were also improved in a dose-dependent manner. This study demonstrates that FGF-21 can ameliorate learning and memory abilities of D-galactose induced aging mice, improve the antioxidant abilities in brain tissue and delay brain aging. This finding provides a theoretical support for clinical application of FGF-21 as a novel therapeutics for preventing aging.

BACKGROUNDCancer stem cells (CSCs) are the cause of cancer recurrence because they are resistant to conventional therapy and contribute to cancer growth and metastasis. Endocrinotherapy is the most common breast cancer therapy and acquired tamoxifen (TAM) resistance is the main reason for endocrinotherapy failure during such therapy. Although acquired resistance to endocrine treatment has been extensively studied, the underlying mechanisms are unclear. We hypothesized that breast CSCs played an important role in TAM-induced resistance during breast cancer therapy. Therefore, we investigated the biological characteristics of TAM-resistant (TAM-R) breast cancer cells.

METHODSMammosphere formation and tumorigenicity of wild-type (WT) and TAM-R MCF7 cells were tested by a mammosphere assay and mouse tumor xenografts respectively. Stem-cell markers (SOX-2, OCT-4, and CD133) and epithelial-mesenchymal transition (EMT) markers were tested by quantitative real-time (qRT)-PCR. Morphological observation was performed to characterize EMT.

RESULTSAfter induction of TAM resistance, TAM-R MCF7 cells exhibited increased proliferation in the presence of TAM compared to that of WT MCF7 cells (P < 0.05), indicating enhanced TAM resistance of TAM-R MCF7 cells compared to that of WT MCF7 cells. TAM-R MCF7 cells showed enhanced mammosphere formation and tumorigenicity in nude mice compared to that of WT MCF7 cells (P < 0.01), demonstrating the elevated CSC properties of TAM-R MCF7 cells. Consistently, qRT-PCR revealed that TAM-R MCF7 cells expressed increased mRNA levels of stem cell markers including SOX-2, OCT-4, and CD133, compared to those of WT MCF7 cells (P < 0.05). Morphologically, TAM-R MCF7 cells showed a fibroblastic phenotype, but WT MCF7 cells were epithelial-like. After induction of TAM resistance, qRT-PCR indicated that MCF7 cells expressed increased mRNA levels of Snail, vimentin, and N-cadherin and decreased levels of E-cadherin, which are considered as EMT characteristics (P < 0.05).

CONCLUSIONTAM-R MCF7 cells possess CSC characteristics and may be responsible for TAM resistance during breast cancer therapy.

OBJECTIVETo observe the expressions of Wnt/beta-catenin and the effects of tanshinone IIA (TII A) on Wnt/beta-catenin signaling pathway in high glucose induced renal tubular epithelial cell transdifferentiation.

METHODSHuman kidney proximal tubular epithelial cells (HK-2) were divided into three groups, i. e., the normal glucose group, the high glucose group, and the high glucose plus tanshinone IIA group. The expression of beta-catenin was observed using immunocytochemical staining. The protein expression of beta-catenin, E-cadherin, and alpha-smooth muscle actin (alpha-SMA) were detected by Western blot. The mRNA levels of beta-catenin and E-cadherin were detected by RT-PCR.

RESULTSCompared with the normal glucose group, both the protein and the mRNA expressions of beta-catenin were significantly enhanced (P < 0.01), the expression of E-cadherin significantly decreased (P < 0.01), the expression of beta-catenin increased in the cytoplasm and nucleus in the high glucose group. TIIA at the final concentration of 100 micromol/L significantly reduced the ectopic expression of beta-catenin. At that concentration, the protein and mRNA expressions of beta-catenin in the nucleus significantly decreased, while the protein and mRNA expressions of E-cadherin were up-regulated. Meanwhile, the expression of alpha-SMA obviously decreased.

CONCLUSIONSWnt/beta-catenin signaling pathway participated in the high glucose induced renal tubular epithelial cell transdifferentiation. TIIA inhibited the transdifferentiation process possibly through down-regulating the activities of Wnt/beta-catenin signaling pathway, thus further playing a role in renal protection.
