ObjectiveTo investigate the effect of early induced finger function training on motor function and activities of daily living (ADL) of stroke patients.Methods60 stroke patients with hemiplegia were randomly divided into the early induced finger function training group (treatment group) and control group with 30 cases in each group. The patients of the control group were treated with routine rehabilitation; while those of the treatment group were added with training of early induced flexion and extension of fingers. All patients of two groups were assessed with Brunnstorm Scale, Fugl-Meyer Assessment, scores of Neurological Functional Deficit, and Modified Barthel Index before and 8～12 weeks after treatment.ResultsAfter treatment, upper limb motor function, hand function and fingers' fine function in the sick side of the patients in the treatment group improved significantly better than that in the control group ( P<0.05～0.01).ConclusionThe early induced finger function training can obviously improve the upper limb motor function and ADL of stroke patients.

The coronavirus disease 2019 (COVID-19) is an acute infectious disease caused by the new severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, which has led to serious worldwide economic burden. Due to the continuous emergence of variants, vaccines and monoclonal antibodies are only partial effective against infections caused by distinct strains of SARS-CoV-2. Therefore, it is still of great importance to call for the development of broad-spectrum and effective small molecule drugs to combat both current and future outbreaks triggered by SARS-CoV-2. Cathepsin L (CatL) cleaves the spike glycoprotein (S) of SARS-CoV-2, playing an indispensable role in enhancing virus entry into host cells. Therefore CatL is one of the ideal targets for the development of pan-coronavirus inhibitor-based drugs. In this study, a CatL enzyme inhibitor screening model was established based on fluorescein labeled substrate. Two CatL inhibitors IMB 6290 and IMB 8014 with low cytotoxicity were obtained through high-throughput screening, the half inhibition concentrations (IC₅₀) of which were 11.53 ± 0.68 and 1.56 ± 1.10 μmol·L^-1, respectively. SDS-PAGE and cell-cell fusion experiments confirmed that the compounds inhibited the hydrolysis of S protein by CatL in a concentration-dependent manner. Surface plasmon resonance (SPR) detection showed that both compounds exhibited moderate binding affinity with CatL. Molecular docking revealed the binding mode between the compound and the CatL active pocket. The pseudovirus experiment further confirmed the inhibitory effects of IMB 8014 on the S protein mediated entry process. In vitro pharmacokinetic evaluation indicated that the compounds had relatively good drug-likeness properties. Our research suggested that these two compounds have the potential to be further developed as antiviral drugs for COVID-19 treatment.

OBJECTIVETo study the relationship between TCM syndrome type and HBV-DNA in serum and peripheral blood mononuclear cells (PBMCs) in chronic hepatitis B (CHB) patients.

METHODSThe serum HBV markers,HBV-DNA levels in serum and PBMCs, were quantitatively detected in 220 CHB patients by PCR method, and TCM syndrome type of 205 patients were differentiated.

RESULTSArranged from low to high, the percentages of CHB patients with the serum HBV-DNA > or = 1.0 x l0(5) copy/mL (high viral loading) in the five syndrome types were as follows: damp-heat retention in middle-jiao syndrome (DHRS, 55.2%), blood stasis blocking collateral syndrome (BSBC), Gan-Shen yin deficiency syndrome (GSYS), Pi-Shen yang deficiency syndrome (PSDS) and Gan stagnation with Pi deficiency syndrome (GSPS, 82.5%), the difference was significant between DHRS and GSPS; those with HBV-DNA in PBMCs infection were: GSYS (27.3%), DHRS (34.3%), BSBC (53.1%) and GSPS (77.2%). The percentage in GSPS was the highest, which was significantly different to that in other syndromes.

CONCLUSIONAmount of serum HBV-DNA and PBMCs HBV-DNA infection has certain correlation with the TCM syndrome type of CHB. The highest percentage of patients with HBV-DNA > or = 1.0 x l0(5) copy/mL and PBMCs HBV-DNA infection presented in CHB patients of GSPS type. We should pay more attention to strengthen genuine qi to eliminate pathogenic factors in treatment of CHB.

Sugarcane stem is an ideal organ for producing foreign pharmaceutical proteins and chemicals by genetic engineering.A perfect promoter driving foreign gene to express strongly and specifically in sugarcane stem is necessary for this purpose.In order to isolate a Sugarcane stem-specific promoter,a fragment of 1968bp nucleotide sequence(Ppst2a)upstream 5' of sugarcane pst2a gene,which was demonstrated to express specifically in sugarcane stem previously was isolated by using chromosomal walking.Bioinformatical analysis of this sequence shows that the sequence contains some typical elements of a promoter.To identify the stem-specific of this promoter,a construct was derived from pCAMBIA1301,which original CaMV 35S promoter was replaced by the 1968bp nucleotide sequence,and named as pCAMBIA1900.Transformations of pCAMBIA1900 and pCAMBIA1301 to leaves and stem pieces of sugarcane were carried out by using particle bombardment.The transient expression of gus showed that the gus expressed specifically in sugarcane with a little higher level compared with CaMV 35S.It is the first report that pst2a promoter is a potential stem-specific promoter which can further be used in transgenes into sugarcane.

Objective To study the cellular immune function in children with kawasaki disease(KD).Methods T lymphocyte subcytes,levels of serum interleukin 2(IL-2) and soluble interleukin 2 receptor(sIL-2R) were determined by APAAP,ELISA met-hods,and a double-antibody “sandwich” enzyme-linked immunosorbent assay respectively in 60 cases.Results During the acute stage of KD,the percentage of CD4 +,the ratio of CD4 +/CD8 +,levels of IL-2 and sIL-2R increased markedly,while the percentage of CD3 + and CD8 + decreased significantly compared with the controls.These changes were more remarkable in patients subsequently developed coronary artery aneurysms than in those with normal appearing coronary artery.Conclusion Marked activation of cellular immune function and immune regulation disorders develop in acute stage of KD patients.

OBJECTIVETo investigate the effects of antibiotic-PMMA (polymethyl-methacrylate) beads combined with external fixator in treatment of infected fracture nonunion.

METHODSTwenty-two cases of infected fracture-nonunions were reviewed involving 20 male and 2 female with an average age of 34.68 years (ranging 21 to 74 years). The data consisted of 9 cases of tibial fractures, 2 distal fractures of the femur, 6 femoral shaft fractures, 3 intertrochanteric fracture of the femur and 2 humeral shaft fractures. The procedure included thorough debridement to wipe out dead bone and granulation tissue, then antibiotic-PMMA bead chains imbedded into the dead space. One week later, secondary debridement was performed, antibiotic-PMMA bead chains were changed according to result of bacterial culture and susceptibility test, and fractures were stabilized with external fixator. Three months after debridement, antibiotic-PMMA bead chains were taken out and bone graft with autogenous iliac cancellous bone chips was performed.

RESULTSThe mean follow-up period was 19.98 months (ranging 15 to 28 months). Infection was controlled in 20 cases. One tibial fracture and 1 intertrochanteric fracture of the femur needed repeated debridement 2 and 3 months after bone grafting respectively,because of infection recurrence and sinus formation. All 22 cases achieved bony union averaged 15.09 weeks after bone grafting with a range of 8 to 24 weeks.

CONCLUSIONThorough debridement, imbedding antibiotic-PMMA bead chains combined with external fixator and staged bone grafting has proven to be effective and simple for treatment of infected fracture nonunion. The antibiotic bead delivers high tissue levels,obliterates dead space, aids bone repair.
