BACKGROUND: Experiments have demonstrated that exogenous basic fibroblast growth factor (bFGF) promotes the growth and survival of skeletal muscle satellite cells, and endogenous bFGF also has obvious effect on muscular repair.But whether bFGF gene transfection has the same effect on extraocular muscle satellite cells is unclear.OBJECTIVE: The goal of this study was to investigate the effect of bFGF gene transfection on the bio-behavior of rat extraocular muscle satellite cells.DESIGN: Single sample observation.SETTING: Department of Ophthalmology, Qingdao University Medical College.MATERIALS: Primary rat extraocular muscle satellite cells were cultured (purity ＞ 90%). Human PEGFP-N3-bFGF eukaryotic expression vector was successfully constructed (reported in other papers).METHODS: This study was carried out in the Central Laboratory of Qingdao University Medical College between September 2005 and December 2006. Experimental intervention and grouping: During the experiment, 3 groups were divided: Experimental group, in which, recombinant PEGFP-N3-bFGF was used for transfection; Control group A, in which, empty-load PEGFP-N3 was used for transfection; Control group B: in which, only F 10 medium (0.1 volume fraction of fetal bovine serum)was used for transfection. Recombinant PEGFP-N3-bFGF plasmid was used to transfect rat extraocular muscle satellite cells cultured in vitro by liposome-mediated transgenic technology. Experimental evaluation: bFGF expression was observed by immubohistochemical method; Transfection efficiency was detected with fluorescence microscope; The protein secretion of bFGF of satellite cells in each group was detected by SBC-ELISA method on the 1st, 3rd, 5th, 9th, 11th, 13th, 15th, 21st and 28th days of culture; The proliferation of rat extraocular muscle satellite cells in each group was detected by methyl thiazolyl tetrazolium(MTT) method; Creatine kinase (CK) activity of cells in each group was determined according to the A value of some standard whose concentration was known.MAIN OUTCOME MEASURES: ① Transfection efficiency of bFGF gene to rat extraocular muscle satellite cells cultured in vitro and bFGF gene expression after transfection; ②bFGF protein secretion after transfection, and effect of bFGF gene transfection on the growth and proliferation of extraocular muscle satellite cells.RESULTS: ① Transfection efficiency of bFGF gene to rat extraocular muscle satellite cells cultured in vitrowas (42.8±1.2)%. ② Immunohistochemical detection showed positive reaction. ②Transfected cells could secrete bFGF protein,which was the highest on the 5th day (662.935 ng/L). ④ The proliferation activity of transfected cells was obviously enhanced, and its A value was significantly higher than that of control group at the same time point (P ＜ 0.05). ⑤CK value was higher than that of the control group from the 5th day after transfection to the end (P ＜ 0.01).CONCLUSION: bFGF gene transfering into rat extraocular muscle satellite cells can make extraocular muscle satellite cells to secrete bFGF, promote cell proliferation, survival and differentiation.

Objective To investigate the role of intrathecal i njection of oxygen in the treatment of patients with craniocerebral injury throu gh the comparison research of intrathecal injection of oxygen and hyperbaric oxy gen on the rehabilitation of patients with craniocerebral injury. Methods A total of 150 patients were divided into three gro ups: the group of intrathecal injection of oxygen, the group treated with hyperb aric oxygen and the group of intrathecal injection of air. CSF was applied via l umbar puncture. The rehabilitative function of patients was observed and the lev el of superoxide dismutase (SOD), malondialedhyde (MDA), and nitrogen monoxide ( NO) in CSF were measured. Results The neurological function of the patients treated w ith oxygen injected intrathecally intrathecal injection of oxygen was improved w as more significanty than that of patients treated with hyperbaric oxygen; the i ncrease of SOD, NO and the decrease of NO were more significant than that in the group treated with hyperbaric oxygen. Conclusion Intrathecal injection of oxygen can improve the rehabilitative function more significantly than the hyperbaric oxygen therapy in the treatment of craniocerebral injury.

BACKGROUND:Transgenosis of basic fibroblast growth factor (bFGF) gene has been successfully performed into the muscle satellite cells of rat extraocular muscles in the previous study of the research group, proving that bFGF could express in the myoblasts of extraocular muscles, also promote cell proliferation and differentiation.OBJECTIVE: To further investigate the methods for regulating the expression of the bFGF in myoblasts following transfection. METHODS: Target gene bFGF was connected with inducing expression vector pcDNA4/T0/myc-His?A, followed by masculine clone sequencing identified by colony PCR and enzyme digestion, EcoR I and Hind III restriction enzyme digestion, as well as Xho I single enzyme verification. C2C12 myoblasts antibiotics sensitivity was screened and finally defined. By use of lipofection transfection technology, cell lines where C2C12 stably expressed pcDNA6/TR were estabolishd and then identified by Western blot. The pcDNA4/TO/myc-His?A-bFGF was transfected into pcDNA6/TR- C2C12 cells. The bFGF expression and secretion in C2C12 cells following tetracycline-induced pcDNA4/TO/myc-His?A-bFGF transfection were determined by immunofluorescence and Western blot, the controls were established.RESULTS AND CONCLUSION: ① The conjunction between the bFGF and inducing expression vector pcDNA4/TO/myc-His?A was proved successfully by sequencing comparison, double digestion and single digestion. ②The minimal lethal concentration of blasticidin to C2C12 cells was 10 mg/L, while that of zeocin was 750 mg/L. ③ The pcDNA6/TR-C2C12 cell lines were established correctly. ④ The myoblasts treated by tetracycline and transfected with pcDNA4/TO/myc-His?A-bFGF were positive for gene expression, those untreated exhibited a negativity; bFGF protein could be produced in myoblasts treated by tetracycline and transfected with pcDNA4/TO/myc-His?A-bFGF, the production reached a peak at 24 hours, while those untreated can not produce bFGF protein. Results suggest that the bFGF expression in the myoblasts can be controlled by tetracycline inhibition and regulatory systems.

Studies have shown that co-infection of influenza viruses with bacteria is an important cause of high mortality during the epidemic of influenza.There are at least 12 species of bacteria that have been reported to be able to co-infect with influenza.Among those species,co-infection with Staphylococcus aureus is not only the most common but also the most lethal.However,the pathogenesis of high mortality from co-infection with influenza virus/S.aureus remains elusive.In addition,co-infection of influenza virus/S.aureus can induce severe pneumonia.There is new evidence that influenza virus can reduce the host′s tolerance to pathogenic or inflammatory injury,and the two pathogens can also synergistically aggravate toxic effects on the host.Here,we review the mechanisms of severe mortality of influenza infection associated with S.aureus co-infections in order to contribute to prevention and control of influenza in the future.

Objective To evaluate the best mean for the treatment of varicocele. Methods The clini-cal effects of the high ligation of spermatic vein under the small incisal opening of the poritneum meta abdom-inal membrane and the ligation of spermatic vein under the laparoscope for the varicocele were retrospectively reviewed. The operating time, the postoperative days and the cost of hospitalization were compared of the two methods. Results Comparing with the group of operation and the group of laparoscope. Among the 158 vat-icocele patients with unilateral or bilateral varicocele, there was not statistical difference in the operating time between the two methods (P > 0. 05), whi]e there was significant difference in the postoperative days and the cost of hospitalization(P <0. 05). Conclusions When the bilateral varicoceles were simultaneously ligated, the high ligation of spermatic vein under the laparoscope was the best selection; if the unilateral varicocele was highly ligated or the patients were unconditional or the patients were not fit for laparoscopic operation, the high ligation of spermatic vein under the small incisal opening of peritoneum was the best operating method.

Objective:To systematically review qualitative research on the experiences of palliative care patients and caregivers in home medication management, so as to improve their drug management capabilities and optimize grassroots palliative care services as a reference.Methods:This review was conducted using databases including the Cochrane Library, PubMed, Embase, Web of Science, CINAHL, China National Knowledge Infrastructure, Wanfang Data, VIP Database, and China Biology Medicine disc, searching for qualitative research on the medication management experiences of palliative care patients and caregivers up to April 30, 2024. The quality of the literature was assessed using the Australian Joanna Briggs Institute Evidence-Based Health Care Center standards for qualitative research quality assessment. A convergent integrated approach was employed to synthesize and integrate the findings.Results:Eleven articles were included, all of which were from abroad, synthesizing 51 findings into 7 new categories, which were then integrated into 3 composite outcomes: complex feelings of patients and caregivers in home medication management, including responsibility and self-efficacy, anxiety and fatigue; challenges in home medication management, including polypharmacy and experiences using pain medication, disagreements over medication management at home, and perceived inadequacies in primary healthcare resources;the need for multifaceted support, including desires for more medication guidance and communication with palliative care professionals in the community.Conclusions:Due to the complexity of medication needs and insufficient regulatory support, home medication management in palliative care presents challenges. It is recommended to enhance the self-efficacy and medication management skills of patients and caregivers, improve risk response capabilities, optimize medication administration processes, and strengthen training for healthcare professionals. Government agencies should also support policies to ensure a safe and comfortable home medication environment for palliative care patients in China.

Objective To explore the safety and feasibility of time of postoperative strict bed rest shorten to one hour among patients with CT-guided percutaneous lung biopsy.Methods From July 2016 to June 2017,we selected 140 patients with CT-guided percutaneous lung biopsy of cancer center at Nanjing Drum Tower Hospital,the Affiliated Hospital of Nanjing University Medical School,by convenience sampling.All of the patients were randomly divided into observation group and control group,70 cases in each group.Patients of observation group kept strict bed rest for one hour and those of control group for six hours by the routine.We compared the incidence of complication and patients' comfort between two groups after surgery using t test and χ2test.Results The total of 140 patients were treated with biopsy successfully without chest infection and asphyxia after surgery.There was no statistical difference in the incidences of pneumothorax and bleeding of patients between two groups (χ2=0.341,0.119;P＞0.05);the comfort of observation group was superior to that of control group six hours after biopsy with a significant difference (t=9.683,P＜0.01).Conclusions The time of postoperative strict bed rest shorten to one hour among patients with CT-guided percutaneous lung biopsy does not increase the incidence of complications after surgery and makes patients feel more comfortable.
