BACKGROUND:Autologous hard palate mucosa has been validated to be a substitute of the tarsal conjunctival. OBJECTIVE:To investigate the treatment outcomes of autologous hard palate mucosa applied in the eyelid reconstruction. METHODS:180 patients (180 eyes) with eyelid defects aged 10-63 years old were recruited, including 122 males and 58 females, and subjected to the transplantation of autologous hard palate mucosa. In the same time, flaps were designed and transferred into the defected eyelid soft tissues. All patients were followed up for over 3 months to observe the treatment outcomes. RESULTS AND CONCLUSION:Three months after surgery, viscous secretions were found in the implanted region and conjunctival sac, which were relieved and eliminated by usage of antibiotic drops. All implanted hard palate mucosa survived within 1 year, neither infections nor falling off occurred, and blood vessels growth into the implant-tissue conjugation that inosculated with the host vessels presenting no rejection. The implants revealed different degrees of shrink in 132 patients, but the eye function was normal. During the hospitalization, some uncomfortable feeling such as eye pain had been relieved, and the wound showed no infections and healed well. During the follow-up, there were eight patients with slight lower eyelid ectropion and three with hypophasis. The length or height difference of both eyelids was within 2 mm, except those who lost eye bal s. These results suggest that autologous hard palate mucosa achieve satisfactory outcomes in the eyelid reconstruction and possesses good histocompatibility.

BACKGROUND: Umbilical cord blood mesenchymal stem cells (UCB-MSCs) can differentiate into various types of cells under certain condisions, and easily proliferate in vitro. However, UCB-MSCs have long establishment time and low frequency.OBJECTIVE: To in vitro isolate and culture UCB-MSCs, and induce its differentiation into osteoblasts.DESIGN, TIM E AND SETTING: The in vitro cytological study was performed at the Laboratory of the Medical College of Qingdao University from June 2008 to January 2009.MATERIALS: UCB was obtained from term normal delivery women at the Department of Gynaecology and Obstetrics, Qingdao Municipal Hospital.METHODS: Human UCB-MSCs were isolated and cultured in vitro by Percoll density gradient. When reached 90% confluency,UCB-MSCs were digested by trypsin for subculture. At the third passage, UCB-MSCs at 1×106 were incubated. When reached 50% 60% cenfluency, UCB-MSCs were treated with DMEM supplemented with 0.1 μmol/L dexamathasone, 10 mmol/Lβ-sodium glycerophosphate and 50 μmol/L vitamin C. UCB-MSCs in the control group were incubated in low glucose DMEM.MAIN OUTCOME MEASURES: Growth and proliferation of MSCs were observed under the inverted microscope. Cell surface marker expression and cell growth curve were measured by flow cytometry. Cell ultrastructure was observed under the transmission electron microscope. Differentiation of UCB-MSCs into osteoblasts was determined by Won Kossa staining and alkaline phosphatase staining.RESULTS: Primary cultured UCB-MSCs had similar morphology to bone marrow mesenchymal stem cells. After passage, cell morphology was even, presenting spindle shape. UCB-MSCs at passage 3 highly expressed CD29, CD44, CD13, but did not express CD34. Growth latency was 2-3 days. Cells entered logarithm proliferation phase at days 3-4, and platform phase 1 month later. Nuclei presented round or irregular, with clear nuclear membrane, 1-2 nucleoli, rough chromatin, abundant organelles and microvilli. UCB-MSCs at passage 3 were gradually confluent following 3 days of osteogenic induction, with the presence of pavement-stone shape. 14 days later, calcified nodules by Von Kossa staining, and cells were positive for alkaline phosphatase staining. In the control group, no calcified nodules were found, and cells were negative for alkaline phosphatase staining.CONCLUSION: UCB-MSCs can be successfully isolated by Percoil density gradient, and induced to differentiate into osteoblasts in vitro.

Objective To investigate the clinical manifestations and treatment regiment of children with juvenile dermatomyositis(JDM).Methods The clinical manifestation,changes of serum muscale enzyme,myopathic laboratory examination,treatment and prognosis of 15 children with JDM retrospectively admitted from Jan.1990 to Jan.2004 were analyzed.Results All of the children had symmetrical weakness of the proximal muscles.The most frequent features were heliotrope and Gottron's papules.Elevated muscle enzymes were noted in all cases.Electromyography revealed typical change of myopathic type and muscle biopsy was compalible with myositis in all cases.Most of patients achieved normal muscle enzymes within 1 month and had improved muscle strength with 2.5 monthes of the initiation of corticosteroid therapy.Conclusion It is very important to know the clinical features of JDM,and prompt diagnosis and treatment will result in an improved prognosis.

To understand the distribution and accumulation rules of polydatin, resveratrol, anthraglycoside B, emodin and physicion in different tissue structure of rhizome and root of Polygonum cospidatum, the content of 5 active compounds were analyzed simultaneously by HPLC, based on plant anatomy and histochemistry. The rhizome and root consist of different tissues, with an increased diameter, the proportions of the secondary xylem and phloem have increased. Resveratrol and polydatin mainly distributed in the pith, the secondary phloem and periderm of rhizome, and the secondary phloem and periderm of the root, while emodin and anthraglycoside B concentrated in the secondary structure and pith of rhizome mostly. In different thickness of the measured samples, the total contents of 5 compounds were correspondingly higher in thinner rhizome and root than those in the coarse ones.

OBJECTIVE: To explore the mutation of Y-STR loci in meiotic allelic transmission in a large pedigree. METHODS: The oral swabs of 163 male individuals were collected from a Lin pedigree. Twenty-two Y-STR genetic markers were typed with AGCU Y24 fluorescent detection kit (AGCU Y24 system), which also contained 16 Y-STR markers included in Yfiler multiple amplification kit (Yfiler system). The genotyping results of Y-STR loci were compared between each two males in the pedigree. RESULTS: There were 20 and 30 kinds of haplotypes obtained with Yfiler and AGCU Y24 systems in 163 male individuals from the Lin pedigree, respectively. The rates referred to haplotype differences (RRHD) of these two typing systems between male pairs were 0.910 5 and 0.922 7, respectively. The average number of marker differences were 6.582 1 and 9.824 8, respectively. The RRHD increased along with the incidents of meiosis. CONCLUSION Y-STR mutation leads to different Y-STR haplotypes among the male members in a paternal pedigree and the rate of difference increases along with the incidents of meiosis.

Purpose: Hemiparesis in stroke survivors has been reported to affect respiratory function. The relationship between trunk control and respiratory function, however, is not well understood. We aimed to map the state of the association between the trunk and respiratory function as well as evaluate the effect of a respiratory function training intervention on trunk control for stroke survivors. Methods: A scoping review and meta-analysis of observational and interventional studies were performed. Cochrane Library, CINAHL with Full Text (EBSCO), Medline (Ovid), and PubMed were searched using the terms stroke, respiratory, and trunk control. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR) checklist was used to examine the sections of each report. Results: A total of 102 studies were identified, of which 12, published between 2011 and 2022, were included in the meta-analysis or narrative synthesis. Three studies were included in the meta-analysis of the correlation between trunk control and respiratory function parameters (forced vital capacity [FVC], forced expiratory volume during the first breath [FEV1], maximal inspiratory pressure [MIP], and maximal expiratory pressure [MEP]) with effect sizes (Fisher's z) for all outcomes, which ranged from small to intermediate (between 0.21 and 0.39). Furthermore, five studies were included in the meta-analysis of the effect of respiratory function training intervention on trunk control. An overall effect size (Cohen's d) of 1.47 corresponds to a large effect. We also found significant improvements in MIP and MEP but not in FVC and FEV1 for stroke survivors with the interventions. Conclusions Respiratory training, use of diaphragmatic resistance exercise or abdominal breathing, use of a pressure threshold-loading device, and the performance of functional strengthening exercises for the trunk muscles were found to increase patients’ trunk control and improve their respiratory muscle strength.
