OBJECTIVE:To promote the working performace of automatic medicine packing machine in our hospital. METH-ODS:Combined with the problems we met in the use of the automatic medicine packing machine,the reconstructions of software functions,such as drug inventory management,drug identification,specific drug sub-package and document printing of non-pack-age drug,were introduced. Related indicators were compared before and after reconstruction. RESULTS:After the software recon-struction,compared with 2012,loss events of expire drug due to poor sales fell by 70% in 2013;drug dispensing errors related to medicine packing machine dropped by 1/2;the time of drug checking shortened by 1/5. CONCLUSIONS:The software program re-construction of automatic medicine packing machine can improve the work efficiency of pharmacy and the accuracy of drug dispens-ing,further guarantee the quality and safety of drugs,and meet the practical demand of our hospital.

Objective: To study the mechanism and effect of Chinese medicine Yiqi Tongyang Huatan prescription(益气通阳化痰方,YQTYHT) on hyperlipidemia and atherosclerosis(AS).Methods: The rabbit′s model was established by feeding the food containing high cholesterol,and 32 rabbits were randomly divided into four groups(each n=8): normal group,model group,Huoxue Huayu prescription treatment group(活血化瘀方,HXHY group) and YQTYHT treatment group(YQTYHT group).Before the experiment,at the end of 6 th and 12 th weeks after the experiment,the following items were measured: blood lipids platelet aggregation rate,platelet adhesion rate,malondialdehyde(MDA),endothelin-1(ET-1),nitric oxide(NO),the ratio of the lipid plaque area and the thickness of the endothelial plaque.Results: After feeding the food containing high cholesterol,the blood lipids,platelet aggregation rate,platelet adhesion rate,MDA,ET1,the ratio of lipid plaque area and the thickness of plaque were elevated significantly,while serum NO3-/NO2-decreased significantly in model group.Compared with the model group,the blood lipids were lower in the two treatment groups,and the blood lipid regulating effect in YQTYHT group was significantly better than that in HXHY group.Platelet aggregation rate and platelet adhesion rate of YQTYHT group and HXHY group were lower than those in the model group,but the degree of lowering in YQTYHT group and HXHY group had no significant differences.The serum MDA of YQTYHT group and HXHY group was lower than that in model group,and the lowering effect in YQTYHT group was better than that in HXHY group.YQTYHT group and HXHY group had a significant increase on the level of serum NO3-/NO2-and a decrease on the content of plasma ET-1,furthermore,the effects in the former group were significantly better than those of the latter group.The area of atherosclerotic plaque coverage in aorta and the thickness of plaque of HXHY group were larger than those in YQTYHT group(both P

Objective To evaluate the clinical efficacy and safety of short-segment pedicle screw fixation combined with vertebroplasty for the treatment of thoracolumbar osteoporotic compression fractures.Methods A retrospective case control study was conducted on 63 patients with fresh thoracic or lumbar osteoporotie compression fractures who were surgically treated from January 2010 to December 2013.There were 26 males and 37 females,with age of 63-87 years [(76.3 ± 5.7) years].According to the surgical method,the patients were assigned to simple vertebroplasty group (Group A),short-segment pedicle screw fixation group (Group B),and short-segment pedicle screw fixation group combined with vertebroplasty group (Group C),with 21 cases in each group.Length of hospital stay,operation time,and blood loss were recorded.The visual analog scale (VAS),anterior vertebral body height,angle of the kyphotic deformity,and complications before operation,immediately after operation,3 months after operation,and at the last follow up were compared among three groups.Complications of each group were recorded.Results The hospital stay,operation time,and blood loss in Group C were significantly higher than those in Group A (P ＜ 0.05),but there were no significant differences between Group B and Group C (P ＞ 0.05),except for a longer operation time in Group C.The pre-operative VAS showed no significant difference among three groups (P ＞ 0.05).However,the mean VAS in Groups A,B and C at the last follow up were 1.0(0.0,2.0)points,1.0(0.0,2.0)points,0.0(0.0,1.0)points,respectively.The VAS in Group C was significantly lower than that in Group B or A (P ＜ 0.05).The mean anterior vertebral body height and angle of the kyphotic deformity in Group C had no significant difference from that in Group A or B before operation and immediately after operation (P ＞ 0.05).At the last follow up,the mean anterior vertebral body height and angle of the kyphotic deformity in Groups A,B and C were (68 ±14.7)％,(72.3 ±9.0)％,(81.5 ±5.6)％ and (10.6 ±3.9)°,(10.7 ±5.0)°,(7.4 ± 5.0) °,respectively.The loss of anterior vertebral body height and angle of the kyphotic deformity correction in Group C were significantly less than that in Group A or B (P ＜ 0.05).Superficial infection was found in Groups B (n =2) and C (n =1),and the infection was cured after antibiotic therapy and dress change.Bone cement leakage was found in Groups A (n =8) and C (n =5),with no nerve compression.Internal fixation failure was seen in Group B (n =3),and the implant was removed directly.Conclusion Short-segment pedicle screw fixation combined with vertebroplasty can effectively reduce the loss of anterior vertebral body height and angle of the kyphotic deformity and hence enhance the clinical efficacy.

Objective:To study the characteristics and clinical significance of mitochondrial injury of T lymphocyte subsets in patients with autoimmune hepatitis (AIH).Methods:The clinical data of 57 patients with AIH (AIH group) from June to December 2021 in Hangzhou Xixi Hospital were retrospectively analyzed, while 60 healthy physical examiners were included as healthy group. The peripheral blood T lymphocyte subsets (CD 8+ T lymphocyte count and CD 4+ T lymphocyte count) were detected by flow cytometry, and matched mitochondrial staining value according to certain algorithm was used to determine the mitochondrial damage of helper T lymphocyte (Th cell) and suppressor T lymphocyte (Ts cell). The levels of IgG, alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were measured using a Roche E170 automatic electrochemiluminescence immunoassay. Anti-nuclear antibody (ANA) titer was measured by immunofluorescence. Multivariate Logistic regression was used to analyze the independent risk factors of mitochondrial damage of Th cell and Ts cell in patients with AIH. Results:The ALT, AST, IgG, positive rate of ANA titer, CD 4+ T lymphocyte count, CD 8+ T lymphocyte count, rate of Th cell mitochondrial injury and rate of Ts cell mitochondrial injury in AIH group were significantly higher than those in healthy group: (118.90 ± 37.61) U/L vs. (30.96 ± 14.37) U/L, (102.40 ± 36.51) U/L vs. (31.12 ± 14.06) U/L, (18.40 ± 3.71) g/L vs. (13.89 ± 1.98) g/L, 96.49% (55/57) vs. 16.67% (10/60), 438 (323, 637) × 10 6/L vs. 398 (272, 469) × 10 6/L, 296 (211, 296) × 10 6/L vs. 270 (193, 322) × 10 6/L, 61.40% (35/57) vs. 8.33% (5/60) and 82.46% (47/57) vs. 11.67% (7/60), and there were statistical differences ( P<0.01 or <0.05). Multivariate Logistic regression analysis result showed that the AST elevated and CD 8+ T lymphocyte count reduced were the independent risk factors of Ts cell mitochondrial injury in patients with AIH ( OR = 1.06 and 0.99, 95% CI 1.01 to 1.10 and 0.99 to 1.00, P<0.05); the ALT elevated and IgG elevated were the independent risk factors of Th cell mitochondrial injury in patients with AIH ( OR = 1.08 and 1.66, 95% CI 1.02 to 1.14 and 1.11 to 2.48, P<0.05). Conclusions:It is of positive clinical significance to measure the T lymphocyte subtype mitochondrial injury in patients with AIH. The probability of mitochondrial injury of T lymphocyte subtype can be predicted by biochemical indexes such as ALT, AST and IgG, so as to indirectly evaluate the liver cell necrosis.
