Abstract
OBJECTIVE To investigate the correlation between bone metabolism markers, bone mineral density (BMD), and sarcopenia. METHODS A total of 331 consecutive patients aged ≥ 60 years who were hospitalized between November 2020 and December 2021 were enrolled. Participants were divided into sarcopenia and non-sarcopenia groups according to the Asian Working Group on Sarcopenia criteria (AWGS, 2019). The clinical data, bone metabolism markers (β-CTX, N-MID, and TP1NP), and BMD were compared between the two groups. RESULTS Age, β-CTX, and N-MID of the sarcopenia group were higher than those of the non-sarcopenia group (P < 0.05), but the BMD T values were lower than those of the non-sarcopenia group (P < 0.05). Binary logistic regression analysis showed that increased femoral neck BMD (FNBMD) was a protective factor for sarcopenia, while increased β-CTX was a risk factor. Pearson/Spearman correlation analysis showed that the diagnostic indices of sarcopenia were positively correlated with FNBMD and negatively correlated with β-CTX and N-MID. Multiple linear regression analysis revealed that BMI and FNBMD significantly positively affected muscle strength and appendicular skeletal muscle mass (ASM). The FNBMD significantly positively affected physical performance, while β-CTX significantly negatively affected muscle strength, ASM, and physical performance. CONCLUSION Increased FNBMD may be a protective factor against sarcopenia, and increased β-CTX may be a risk factor. The FNBMD significantly positively affected the diagnostic indices of sarcopenia, while β-CTX significantly negatively affected them. BMD and bone metabolism marker levels may be considered in early screening for sarcopenia.

Abstract
Objective: To analyze effects of cooperation between physicians in department of burn surgery and department of intensive care medicine on rescue and treatment of severe mass burn patients involved in August 2nd Kunshan factory aluminum dust explosion accident. Methods: On August 2nd, 2014, 15 extremely severe burn patients involved in August 2nd Kunshan factory aluminum dust explosion accident were admitted to temporary burn treatment center established in Department of Critical Care Medicine of the Second Affiliated Hospital of Soochow University. The 15 patients were equally divided into 3 groups, with 5 patients in each group. Fifteen surgeons and 30 nurses from department of burn surgery and 15 physicians and 30 nurses from department of intensive care medicine from different hospitals in China were divided into 3 groups, with 5 physicians and 10 nurses from department of burn surgery and 5 physicians and 10 nurses from department of intensive care medicine in each group. Each group of physicians and nurses were responsible for treatment of 5 patients. Treatment of patients was leaded by surgeons from department of burn surgery, who were responsible for wound dealing and operation. Physicians from department of intensive care medicine were responsible for systemic treatment and adjustment of relevant equipment's parameters. Volume of fluid infusion and urine output in shock period, severe systemic complication during period of treatment, using time and kind of antibiotics, death in 1 month after admission, length of hospital stay, and survival of patients were monitored. Results: Volume of fluid infusion of 15 extremely severe burn patients within the first 24 hours post injury was 10 360-17 162 (12 998±1 811) mL, including (1.62±0.23) mL·% total body surface area (TBSA)(-1)·kg(-1) electrolyte and colloid and (2 850±232) mL glucose, with electrolyte and colloid ratio of (1.76±0.23)∶1.00. Volume of urine output within the first 24 hours post injury was (2 384±1 242) mL, with (99±52) mL in each hour. Volume of fluid infusion of 15 extremely severe burn patients within the second 24 hours post injury was 8 720-11 616 (9 406±1 277) mL, including (1.04±0.22) mL·%TBSA(-1)·kg(-1) electrolyte and colloid and (2 910±187) mL glucose, with electrolyte and colloid ratio of (1.53±0.31)∶1.00. Volume of urine output within the second 24 hours post injury of patients was (2 299±1 362) mL , with (108±61) mL in each hour. One patient had pulmonary infection, and 7 patients had fungal infection, and no patient had gut microbiota dysbiosis. Patients were treated with combined 2 kinds of antibiotics for 21-85 (50±16) d. No patient died within 1 month after admission. The length of hospital stay was 53-132 (98±44) d. Ten patients survived finally. Conclusions: After being treated by cooperation between physicians in department of burn surgery and department of intensive care medicine, severe mass burn patients involved in August 2nd Kunshan factory aluminum dust explosion accident had hemodynamic stability and could stably experience shock period, with less complication, shorter length of hospital stay, no death within 1 month after admission, more survived patients, which can provide reference for rescue and treatment of severe mass burn patients.

Abstract
The objective of this study was to examine hepatitis B virus (HBV) subgenotypes and mutations in enhancer II, basal core promoter, and precore regions of HBV in relation to risks of liver cirrhosis (LC) and hepatocellular carcinoma (HCC) in Southeast China. A case-control study was performed, including chronic hepatitis B (CHB; n=125), LC (n=120), and HCC (n=136). HBV was genotyped by multiplex polymerase chain reaction and subgenotyped by restriction fragment length polymorphism. HBV mutations were measured by DNA sequencing. HBV genotype C (68.2%) predominated and genotype B (30.2%) was the second most common. Of these, C2 (67.5%) was the most prevalent subgenotype, and B2 (30.2%) ranked second. Thirteen mutations with a frequency >5% were detected. Seven mutation patterns (C1653T, G1719T, G1730C, T1753C, A1762T, G1764A, and G1799C) were associated with C2, and four patterns (C1810T, A1846T, G1862T, and G1896A) were associated with B2. Six patterns (C1653T, G1730C, T1753C, A1762T, G1764A, and G1799C) were obviously associated with LC, and 10 patterns (C1653T, G1730C, T1753C, A1762T, G1764A, G1799C, C1810T, A1846T, G1862T, and G1896A) were significantly associated with HCC compared with CHB. Four patterns (C1810T, A1846T, G1862T, and G1896A) were significantly associated with HCC compared with LC. Multivariate regression analyses showed that HBV subgenotype C2 and C2-associated mutation patterns (C1653T, T1753C, A1762T, and G1764A) were independent risk factors for LC when CHB was the control, and that B2-associated mutation patterns (C1810T, A1846T, G1862T, and G1896A) were independent risk factors for HCC when LC was the control.

Abstract
The complete mitochondrial genome of the oriental fruit fly Bactrocera dorsalis s.s. has been sequenced, and is here described and compared with the homologous sequences of Bactrocera oleae and Ceratitis capitata. The genome is a circular molecule of 15,915 bp, and encodes the set of 37 genes generally found in animal mitochondrial genomes. The structure and organization of the molecule is typical and similar to the two closely related species B. oleae and C. capitata, although it presents an interesting case of putative intra-molecular recombination. The relevance of the growing comparative dataset of tephritid complete mitochondrial genomes is discussed in relation to the possibility to develop robust assays for species discrimination in quarantine and agricultural monitoring practices, as well as basic phylogeography/population genetic studies.

Abstract
PURPOSE To evaluate sequential pathologic and immunologic changes and their prognostic significance after percutaneous microwave coagulation therapy (PMCT) of hepatocellular carcinoma (HCC). METHODS Eighty-nine nodules in 82 consecutive patients were studied. The 89 nodules were divided into two groups: a treatment group, with 82 primary nodules (average dimension was 3.4 +/- 1.2 cm) in 82 patients, and a control group, of seven nodules (average dimension was 1.4 +/- 0.6 cm) in seven patients. The criteria for a nodule's inclusion in the control group was that the nodule was one of two nodules in the same patient and that the two nodules were located in different liver lobes. This guarantees that while one nodule is treated by PMCT, the distant one will not be directly affected by the microwave thermal field. The control group nodules were treated after the study was completed. Specimens were taken with ultrasound-guided liver biopsy from the treated nodule and the control nodule, pre- and post-PMCT. Infiltration by T-lymphocytes, B-lymphocytes, NK cells and macrophages in the tumour tissue were observed immunohistochemically using a panel of monoclonal antibodies against CD3, CD45RO, CD20, CD56 and CD68. The extent of immune cell infiltration was compared both before and after PMCT, as well as between the treated and control nodules. The relationship between the prognosis and the extent of immunocyte infiltration was analysed. RESULTS The patients were followed for 2-26 months (mean 14.6 +/- 6.3) post-treatment. The recurrence rates at 1 and 2 years were 20.4% and 28.1% within the liver in treatment group, respectively. The survival rates at 1 and 2 years were 92.5% and 75.3% for the treatment group. T-cells, NK cells and macrophages increased significantly in both treated and untreated nodules after PMCT, albeit less markedly within untreated nodules when compared to the treated ones. There is a statistically significant correlation between survival outcome and the extent of immunocyte infiltration. CONCLUSIONS For inoperable HCC patients, PMCT is one of the treatment choices shown to be effective. Apart from its tissue coagulation effect, an increased systemic immune response directed against the tumour may also play an important role in improved survival.

Abstract
MRL-Fas(lpr) mice spontaneously develop a chronic lupus-like renal disease, characterized by immune complex-mediated glomerulonephritis and abundant mononuclear cell infiltration in the interstitium. In the present study we have examined whether the macrophage chemoattractant osteopontin (Opn) could be important in the recruitment of macrophages in this murine model of autoimmune renal injury. We have examined the expression of Opn in the kidney of MRL-Fas(lpr) mice and have correlated Opn synthesis with the degree of macrophage infiltration. Immunofluorescence staining revealed prominent expression of Opn by proximal tubules in MRL-Fas(lpr) mice but not in MRL-++ control mice. Northern blot analysis demonstrated that steady-state transcript levels for Opn mRNA were also significantly increased in MRL-Fas(lpr) kidneys compared with control kidneys. Furthermore, in situ hybridization showed massive Opn mRNA transcripts in proximal tubules in MRL-Fas(lpr) mice but not in controls. The diffuse macrophage infiltration in the kidney of MRL-Fas(lpr) correlated with the enhanced Opn expression. Opn secretion in vitro by cultured renal tubular epithelial cells was upregulated by TNF-alpha and 1,25(OH)2-vitamin D3, whereas no regulation was observed in a control macrophage cell line. We conclude that the enhanced expression of the chemotactic molecule Opn by tubular cells is a prominent feature of murine lupus nephritis and might be promoted by the proinflammatory cytokine environment in MRL-Fas(lpr). The chronic upregulation of Opn could participate in the recruitment of monocytes in the kidney of MRL-Fas(lpr) mice, thereby contributing to the pathogenesis of autoimmune renal disease.

Abstract
The expression of surface antigens on both normal adult's bone marrow and multipotential progenitor cells (CFU-Mix) was detected by use of ABC technique. The culture system of CFU-Mix was an ideal model for studying the differentiation direction of hematopoietic cells. The monoclonal antibodies (McAb) CD3, CD4, CD8 specific for T-lymphocytic lineage, CD22 for B-lymphocytic lineage and CD11, CD13, CD14 for granulocytomonocytic lineage were all demonstrated in certain proportion in cultured CFU-Mix, which might be associated with the control of hematopoiesis. A decrease in the positive rate of OKT9 and CD34 in cultured cells might be related to the differentiation of hematopoietic cells. SZ-2 and SZ-21 could contribute to the identification of the presence of megakaryocytes in CFU-Mix.

Abstract
By use of transmission electron microscope we demonstrated that the limiting dilution assay is an important method for investigating differentiation of hemopoietic cells in vitro. If various growth factors were added into this culture system, the stem cells of normal adults could differentiate into erythrocyte, granulocyte, megakaryocyte and macrophage, while leukemic progenitor cells could not. The colony forming cell in leukemia still had the nature of leukemic cell.

Abstract
We observed CFU-Mix of 4 normal adults and 11 cases of leukemia. The culture system used by us in this study represented a suitable model for studying differentiation of hemopoietic stem cells in vitro. The pathogenesis of myeloid-lymphoid bipotent leukemia were malignant changes in pluripotent hemopoietic progenitor cells. The leukemic clones showed proliferation, but did not mature in culture. It is suggested that differentiation of leukemic stem cell did not pass through CFU-Mix stage.

Abstract
Karyotypes and in vitro cultures of bone marrow cells from eleven patients with acute myelogenous leukemia M2 type were performed. 8/21 translocation was found in 5 patients. In all of them the cultures in vitro shared one characteristic, i.e., clusters were small and less in number. These patients could relatively easily obtain complete remission. The similarity of CFU-GM in patients with t (8; 21) may be another important biological phenotype.

Abstract
By limiting dilution assay, CFU-Mix of 47 cases of untreated leukemia, myelodysplastic syndrome and 30 cases of normal adults were studied. It is suggested that most cases of acute nonlymphocytic leukemia, like chronic myelogenous leukemia (CML) and myelodysplastic syndrome should have defect in pluripotent hemopoietic stem cell. The CFU-Mix of acute myelogenous leukemia (AML) and CML were obviously lower than that of normal adults (p less than 0.001). By light microscopy, scanning and transmission electron microscopy, it was confirmed that the CFU-Mix colonies, of leukemic patients were chiefly composed of leukemic cells. Their incorporating rate of 3H-TdR was high in the early stage of culture, but that of 55 + 59Fe was low in the whole course. This phenomenon was quite different from that of the normal adults in that the CFU-Mix of the patients showed distinctive proliferation and differentiation into the leukemic progenitor cells.
