OBJECTIVETo discuss arthroscopic technique of single Kirschner wire and suture avoiding epiphyseal line fixation for tibial intercondylar eminence fracture and its clinical results.

METHODSFrom May 2008 to December 2012, 21 patients (13 males, 8 females, ranging in age from 6 to 14 years old) with tibial intercondylar eminence fracture were treated arthroscopically with single Kirschner wire and suture avoiding epiphyseal line fixation technique. According to Meyers and McKeever classification, 7 patients were type II, 10 patients were type III, and 4 patients were type IV. Active rehabilitation began at one week after operation. The patients were followed up for 10 to 30 months. X-ray films were taken to evaluate fracture healing at 1, 3, 6 months after operation; range of motion, the anterior drawer test, the lachman test and the Lysholm knee score were used to evaluate clinical effects.

RESULTSAll fractures were healed without displacement at 6 weeks after operation. Anterior drawer test and the lachman test were both negative in all patients at 3 months after operation. Lysholm knee score was 95.5 ±2.5 at 6 months after operation, and postoperative X-ray film did not find epiphyseal line broadening or narrowing.

CONCLUSIONArthroscopic treatment for tibial eminence intercondylar fracture with single Kirschner wire and 8-shaped suture avoiding epiphyseal line fixation technique has many advantages, such as firm fixation,early mobilization, less invasive, less injury of physis and satisfactory effect.

OBJECTIVETo study the mechanism of spontaneous rupture of hepatocellular carcinoma (HCC).

METHODSThe specimens of 30 patients with ruptured HCC and 30 patients with non-ruptured HCC were collected. Immunofluorescence, immunohistochemical and flow cytometry techniques were used to detect the phagocytosis of macrophages and the deposition of immune complex (IC) on vascular wall.

RESULTSIn this study, the poor function of macrophage phagocytosis was found in patients with ruptured HCC, which could results in the cumulating of IC and deposition on vascular wall. The IC, which composed of hepatitis B virus e1 antigen (HBeAg/1), complement C1q and immunoglobulins, was found deposited in the elastic membrane of arteries. Likely as a result of IC deposition, vascular injury occurs mainly in the small arteries where the deposition of IC was present. As the small arteries were the blood vessels with predominant injury, they would likely to be the ones to split and cause hemorrhage and rupture of HCC during vascular load increase.

CONCLUSIONSWe would conclude that the poor function of macrophage phagocytosis, which lead to the IC deposition and vascular injury may be the factors involved in the pathogenesis of ruptured HCC.

Abstract: Objective　To analyze the epidemic characteristics of hand, foot and mouth disease (HFMD) in Nanping City, Fujian province and to provide the basis for formulating effective prevention and control measures as well as evaluating the efficacy of prevention and treatment. Methods　Descriptive epidemiological method was used to analyze the incidence data of HFMD in Nanping City from 2012 to 2021. Results　A total of 49 231 cases of HFMD were reported in Nanping City from 2012 to 2021. The incidence fluctuated greatly over the 10-year period, ranging from 76.10/100 000 to 308.93/100 000, with an average incidence of 184.99/100 000 per year. The overall incidence and the number of cases showed a fluctuating downward trend over time, but the incidence was high in the next year, and there were statistically significant differences in the incidence rates between different years(χ2=8 169.176, P<0.001). There were significant regional differences in the incidence, the top three average annual incidence rates were: Guanze County (370.76/100 000), Zhenghe County (295.31/100 000) and Wuyishan City (250.31/100 000). There were two peaks of HFMD incidence each year, with the first occurring in May and June and the second occurring in September and October. The incidence rate was higher among males (215.86/100 000) than females (152.93/100 000), and males were more susceptible than females (RR=1.412, 95%CI=1.387-1.438). The cases were mainly aged 0-4 years, accounting for 86.25% (42 461/49 231) of all cases, and the incidence rate gradually decreased with increasing age (χ2trend=570,105.801, P<0.001). The majority of cases (85.22%, 41 953/49 231) occurred in children living in scattered areas, followed by children in kindergartens (12.39%, 6 101/49 231). The etiological results showed a total of 3 476 laboratory-confirmed cases, and the proportion of three (classes) of enterovirus positivity varied each year, with different pathogen compositions showing statistical significance (χ2=584.613, P<0.001). In addition to the years 2015-2017, during which Cox A16 and EV71 were the dominant strains, other years were dominated by other enteroviruses, with EV71 being the main type in severe and fatal cases of HFMD in Nanping City. Conclusion　Nanping City should strengthen health education for children living in the diaspora and in day-care centers, enhance surveillance of epidemics and pathogenology, improve vaccination rates against EV71, focus on the detection and typing of other enteroviruses, and implement effective prevention and control measures for HFMD.

OBJECTIVE: To determine deformity correction by postural correction and subsequent balloon inflation in acute vertebral compression fractures (OVCFs) and to examine the effect of bone mineral density on deformity correction. METHODS: A totol of 50 acute OVCFs received balloon kyphoplasty. Lateral radiographs were taken and analyzed at five different time points : 1) preoperative, 2) after placing the patient in prone hyperextended position, 3) after balloon inflation, 4) after deposition of the cement, and 5) postoperative. All fractures were analyzed for height restoration of anterior (Ha), middle (Hm) and posterior (Hp) vertebra as well as Cobb angle and Kyphotic angle. The bone mineral density (BMD) of lumbar spine was measured by dual-energy X-ray absorptiometry. According to the T-score, the patients were divided into two groups which were osteoporosis group and osteopenia group. RESULTS: Postoperative measurements of Ha, Hm and the Cobb angle demonstrated significant reduction of 4.62 mm, 3.66 mm and 5.34degrees compared with the preoperative measurements, respectively (each p<0.05). Postural correction significantly increased Ha by 5.51 mm, Hm by 4.35 mm and improved the Cobb angle by 8.32degrees (each p<0.05). Balloon inflation did not demonstrate a significant improvement of Ha, Hm or the Cobb angle compared with baseline prone hyperextended. Postural correction led to greater improvements of Ha, Hm and Cobb angle in osteoporosis group than osteopenia group (each p<0.05). CONCLUSION: In acute OVCFs, the height restoration was mainly attributed to postural correction rather than deformity correction by balloon inflation. BMD affected deformity correction in the process of postural correction.

OBJECTIVEStudy blood vessel injury and gene expression indicating vascular endothelial cell apoptosis induced by mannitol with and without administration of anti-oxidative vitamins.

METHODSHealthy rabbits were randomly divided into four groups. Mannitol was injected into the vein of the rabbit ear in each animal. Pre-treatment prior to mannitol injection was performed with normal saline (group B), vitamin C (group C) and vitamin E (group D). Blood vessel injury was assessed under electron and light microscopy. In a second experiment, cell culture specimen of human umbilical vein endothelial cells were treated with mannitol. Pre-treatment was done with normal saline (sample B), vitamin C (sample C) and vitamin E (sample D). Total RNA was extracted with the original single step procedure, followed by hybridisation and analysis of gene expression.

RESULTSIn the animal experiment, serious blood vessel injury was seen in group A and group B. Group D showed light injury only, and normal tissue without pathological changes was seen in group C. Of all 330 apoptosis-related genes analysed in human cell culture specimen, no significant difference was seen after pre-treatment with normal saline, compared with the gene chip without pre-treatment. On the gene chip pre-treated with vitamin C, 45 apoptosis genes were down-regulated and 34 anti-apoptosis genes were up-regulated. Pre-treatment with vitamin E resulted in the down-regulation of 3 apoptosis genes.

CONCLUSIONVitamin C can protect vascular endothelial cells from mannitol-induced injury.

OBJECTIVETo detect succinate dehydrogenase (SDH) of sperm mitochondria by an improved method, and to evaluate the relationship between SDH and the motility and viability of sperm.

METHODSIn 46 fertile and infertile men (aged from 25 to 36), the motility, viability and mitochondrial SDH of sperm were detected by computer-assisted semen analysis system, dead/live sperm molecular fluorescent probe and an improved cytochemical method. Then, the correlation between the motility and viability of sperm and the positive percentage of sperm mitochondrial SDH were analyzed.

RESULTSIn the 46 fertile and infertile men, the motility and viability of sperm were (67.33 +/- 7.37)% and (79.78 +/- 7.65)%, and the positive percentage of sperm mitochondrial SDH was (74.74 +/- 8.29)%. The motility and viability of sperm and positive percentage of sperm mitochondrial SDH had significant correlation (r = 0.901, P < 0.01; r = 0.876, P < 0.01; r = 0.917, P < 0.01).

CONCLUSIONSDetection of sperm mitochondrial SDH has significance in evaluation of sperm mitochondrial function and may serve as an assisted marker of sperm viability.

Endoplasmic reticulum (ER) stress occurs in macrophage-rich areas of advanced atherosclerotic lesions and contributes to macrophage apoptosis and subsequent plaque necrosis. The purpose of the present study was to investigate the effects of caveolin-1 (Cav-1) on ER stress-induced apoptosis in cultured macrophages and the underlying mechanisms. RAW264.7 cells were incubated with thapsigargin (TG) to establish ER stress model. And Cav-1 expression was detected by Western blot. After being pretreated with filipin(III), a caveolae inhibitor, RAW264.7 cells were assayed with flow cytometry and confocal laser scanning microscopy to detect cell apoptosis. Moreover, p38 mitogen-activated protein kinase (MAPK) phosphorylation and C/EBP homologous protein (CHOP) expression were detected with Western blot. The results showed that Cav-1 expression was markedly increased at early stage of TG treatment (P < 0.05) and then decreased with prolonged or high dose TG treatments. The increasing of Cav-1 expression induced by TG in RAW264.7 cells was abolished under inhibition of caveolae by filipin(III) (P < 0.05). The effect of TG on apoptosis of RAW264.7 cells was further augmented after pretreatment with filipin(III) (P < 0.05). Western blotting showed that MAPK phosphorylation induced by TG was inhibited by filipin(III) in RAW264.7 cells (P < 0.05), whereas CHOP remained unchanged (P > 0.05). These results suggest that Cav-1 may play a critical role in suppressing ER stress-induced macrophages apoptosis in vitro, and one of the mechanisms may be correlated with the activation of p38 MAPK prosurvival pathway.
