Objective To evaluate the clinical value of transcranial Doppler ultrasonography(TCD) in detecting cerebral hemooynamic changes at the early stages of cerebrovascular disease in the diabetics.Methods TCD was used to measure the peak wave in the spectra,the pulsatility index(PI) and the mean blood flow velocity(Vm) of each cerebral artery in 142 normotensive type 2 diabetic patients without clinical symptoms of cerebrovascular disease and 62 age and gender matched healthy controls.Results The incidence of cerebral hemodynamic changes detected with TCD was 87.3% in diabetic patients,whose PI for each cerebral artery was significantly higher than those in the controls.Significant increases in the Vm of the extracranial nternal carotid artery,the middle cerebral artery and the basilar artery were detected in the diabetic patients when compared with the controls,suggesting lowered cerebrovascular compliance and smaller vascular diameter in the patients,which leaded to indicate that the pathological changes had spread to the intemal carotid artery and the vertebral artery system.Conclusion TCD can be helpful in detecting cerebral hemodynamic changes at the early stages of cerebrovascular disease in the diabetics.

Objective To compare the outcomes of Dresden technique versus open surgery for acute Achilles tendon ruptures.Methods From January 2013 to June 2017,67 patients were operatively treated for acute Achilles tendon rupture at Department of Orthopaedics,China Japan Friendship Hospital.Of them,Dresden technique was used in 32(minimally invasive group) and open surgery in 35(open surgery group).The 2 groups were compared in terms of baseline characteristics,operation time,operative incision length,hospital stay,postoperative complications like incision infection and tendon re-rupture and the Achilles Tendon Total Rupture Score(ATRS).Results The 2 groups were compatible due to insignificant differences in the baseline characteristics(P>0.05).They were followed up for 18 months.The minimally invasive group had significant shorter operation time(40.0min),incision length(3.0cm) and hospital stay(5 d) than the open surgery group(42.5 min,10.0 cm and 6 d)(P<0.05).No sural nerve lesion was observed in either group.The rate of wound complications was 0% for the minimally invasive group and 8.6% for the open surgery group;the rate of re-rupture was 3.1% for the former and 2.9% for the latter;the ATRS at the final follow-up was 98.0 for the former and 98.5 for the latter.There were no significant differences between the 2 groups in the above comparisons(P>0.05).Conclusions Percutaneous suture of the Achilles tendon with the Dresden instruments is a safe,fast and standardized surgical procedure for acute Achilles tendon ruptures,leading to shorter operation time,incision length and hospital stay,better functional recovery and a tendency of decreased wound complications than the open surgery.

To meet the needs of management of medical case information and biospecimen simultaneously, we developed a novel medical case information system integrating with biospecimen management. The database established by MS SQL Server 2000 covered, basic information, clinical diagnosis, imaging diagnosis, pathological diagnosis and clinical treatment of patient; physicochemical property, inventory management and laboratory analysis of biospecimen; users log and data maintenance. The client application developed by Visual C++ 6.0 was used to implement medical case and biospecimen management, which was based on Client/Server model. This system can perform input, browse, inquest, summary of case and related biospecimen information, and can automatically synthesize case-records based on the database. Management of not only a long-term follow-up on individual, but also of grouped cases organized according to the aim of research can be achieved by the system. This system can improve the efficiency and quality of clinical researches while biospecimens are used coordinately. It realizes synthesized and dynamic management of medical case and biospecimen, which may be considered as a new management platform.

OBJECTIVE To study the inhibitory effects and possible mechanism of naringenin on the activation of hepatic stellate cells. METHODS Using human hepatocytes LO2 as reference, based on drug intervention concentration screened by MTT assay, the effects of naringenin (Western blot assay and trypan blue staining test in 10, 20, 40 μmol/L, immunofluorescence assay in 40 μmol/L) on the expressions of liver fibrosis markers protein (collagen Ⅰ, α-SMA) and mRNA (α1-pro collagen Ⅰ, α-SMA) in human hepatic stellate cells LX2, and the expressions of cell apoptosis and apoptosis-related proteins (Bcl-2, Bax, cleaved caspase-3) were investigated. The apoptosis agents (Z-VAD-FMK, FMK), ferroptosis pathway inhibitor ferrostatin-1, and programmed death pathway inhibitor necrostatin-1 were used to verify the mechanism of the above effects. RESULTS The naringenin could significantly down-regulate protein expressions of collagen Ⅰ (except for naringenin 10 μmol/L) and α-SMA, mRNA expressions of α1-pro collagen Ⅰ (except for naringenin 10 μmol/L) and α-SMA (P<0.05); it also induced LX2 cell apoptosis and increased its apoptotic ratio, down-regulated the protein expression of Bcl-2 while up-regulated the protein expressions of Bax (except for naringenin 10 μmol/L) and cleaved caspase-3 (except for naringenin 10 μmol/L). FMK could reverse above effects of naringenin on LX2 cells (P<0.05). CONCLUSIONS Naringenin can inhibit the activation of hepatic stellate cells LX2 through activating the cell apoptosis signal, which plays ameliorative role in liver fibrosis.
