Abstract
BACKGROUND Some hydatid cysts of cystic echinococcosis type 1 (CE1) lack well-defined cyst walls or distinctive endocysts, making them difficult to differentiate from simple hepatic cysts. AIM To investigate the diagnostic methods for atypical hepatic CE1 and the clinical efficacy of laparoscopic surgeries. METHODS The clinical data of 93 patients who had a history of visiting endemic areas of CE and were diagnosed with cystic liver lesions for the first time at the People's Hospital of Xinjiang Uygur Autonomous Region (China) from January 2018 to September 2023 were retrospectively analyzed. Clinical diagnoses were made based on findings from serum immunoglobulin tests for echinococcosis, routine abdominal ultrasound, high-frequency ultrasound, abdominal computed tomography (CT) scan, and laparoscopy. Subsequent to the treatments, these patients underwent reexaminations at the outpatient clinic until October 2023. The evaluations included the diagnostic precision of diverse examinations, the efficacy of surgical approaches, and the incidence of CE recurrence. RESULTS All 93 patients were diagnosed with simple hepatic cysts by conventional abdominal ultrasound and abdominal CT scan. Among them, 16 patients were preoperatively diagnosed with atypical CE1, and 77 were diagnosed with simple hepatic cysts by high-frequency ultrasound. All the 16 patients preoperatively diagnosed with atypical CE1 underwent laparoscopy, of whom 14 patients were intraoperatively confirmed to have CE1, which was consistent with the postoperative pathological diagnosis, one patient was diagnosed with a mesothelial cyst of the liver, and the other was diagnosed with a hepatic cyst combined with local infection. Among the 77 patients who were preoperatively diagnosed with simple hepatic cysts, 4 received aspiration sclerotherapy of hepatic cysts, and 19 received laparoscopic fenestration. These patients were intraoperatively diagnosed with simple hepatic cysts. During the follow-up period, none of the 14 patients with CE1 experienced recurrence or implantation of hydatid scolices. One of the 77 patients was finally confirmed to have CE complicated with implantation to the right intercostal space. CONCLUSION Abdominal high-frequency ultrasound can detect CE1 hydatid cysts. The laparoscopic technique serves as a more effective diagnostic and therapeutic tool for CE.

Abstract
OBJECTIVE Protein disulfide isomerase A2 (PDIA2), a member of the protein disulfide isomerase family, plays a key role in the folding of nascent proteins in the endoplasmic reticulum by forming disulfide bonds, together with enzymes such as thiol isomerase, oxidase, and reductase. This study investigated the clinical significance and potential functions of PDIA2 in glioma. METHODS The expression of PDIA2 in gliomas was explored using The Cancer Genome Atlas and Gene Expression Omnibus databases. We analyzed the clinical characteristics of glioma patients and the prognostic and diagnostic value of PDIA2 expression. Kaplan-Meier and Cox regression analyses were used to examine the effect of PDIA2 expression on overall survival, progression-free interval, and disease-specific survival. Furthermore, we performed Gene Set Enrichment Analysis and immune infiltration analysis to investigate the functions of PDIA2. PDIA2 mRNA and protein expression was evaluated in cell lines and glioma tissues. RESULTS PDIA2 was expressed at low levels in glioma patients. Kaplan-Meier survival analysis showed that glioma patients with low PDIA2 levels had a worse prognosis than those with high PDIA2 levels. Receiver operating characteristic curve analysis indicated the diagnostic and prognostic ability of PDIA2 (area under the curve = 0.918). Pathways associated with PD1, PI3K/AKT, cancer immunotherapy via PD1 blockade, Fceri-mediated NF-kB activation, FOXM1, and DNA repair were enriched in glioma patients with low levels of PDIA2. PDIA2 expression levels were negatively correlated with immune cell infiltrate levels. CONCLUSION PDIA2 levels are significantly downregulated in glioma. PDIA2 expression may be a potential biomarker for the diagnosis and prognosis of glioma patients.

Abstract
Herein, we describe a stereoselective sulfa-Michael/aldol cyclization reaction promoted by a rationally designed novel axially chiral styrene-based organocatalyst. A variety of highly substituted tetrahydrothiophenes featuring an alkyne-substituted quaternary stereogenic center are obtained in good yields, excellent stereoselectivities, and exclusive trans selectivities. This process tolerates a broad range of alkynyl-substituted acrylamides under mind conditions. The utility of this approach is highlighted in its excellent asymmetric introduction, scalability, and attractive product diversification.

Abstract
An axially chiral styrene-based organocatalyst, featuring a combination of axially chiral styrene-based structure and a pyrrole ring, has been designed and synthesized. This catalyst demonstrates remarkable capabilities in producing a wide range of densely substituted spirooxindoles that feature an alkyne-substituted quaternary stereogenic center. These spirooxindoles are generated through mild cascade Michael/cyclization reactions, resulting in high conversion rates and exceptional enantioselectivity. Our catalytic model, based on experiments, X-ray structure analysis and DFT calculations suggests that chiral matched π-π interactions and multiple H-bonds between the organocatalyst and substrates play significant roles in controlling the stereoselectivity of the reaction.

Abstract
BACKGROUND Intracranial hemorrhage after spinal surgery is a rare and devastating complication. AIM To investigate the economic burden, clinical characteristics, risk factors, and mechanisms of intracranial hemorrhage after spinal surgery. METHODS A retrospective cohort study was conducted from January 1, 2015, to December 31, 2022. Patients aged ≥ 18 years, who had undergone spinal surgery were included. Intracranial hemorrhage patients were selected after spinal surgery during hospitalization. Based on the type of spinal surgery, patients with intracranial hemorrhage were randomly matched in a 1:5 ratio with control patients without intracranial hemorrhage. The patients' pre-, intra-, and post-operative data and clinical manifestations were recorded. RESULTS A total of 24472 patients underwent spinal surgery. Six patients (3 males and 3 females, average age 71.3 years) developed intracranial hemorrhage after posterior spinal fusion procedures, with an incidence of 0.025% (6/24472). The prevailing type of intracranial hemorrhage was cerebellar hemorrhage. Two patients had a poor clinical outcome. Based on the type of surgery, 30 control patients were randomly matched in 1:5 ratio. The intracranial hemorrhage group showed significant differences compared with the control group with regard to age (71.33 ± 7.45 years vs 58.39 ± 8.07 years, P = 0.001), previous history of cerebrovascular disease (50% vs 6.7%, P = 0.024), spinal dura mater injury (50% vs 3.3%, P = 0.010), hospital expenses (RMB 242119.1 ± 87610.0 vs RMB 96290.7 ± 32029.9, P = 0.009), and discharge activity daily living score (40.00 ± 25.88 vs 75.40 ± 18.29, P = 0.019). CONCLUSION The incidence of intracranial hemorrhage after spinal surgery was extremely low, with poor clinical outcomes. Patient age, previous stroke history, and dura mater damage were possible risk factors. It is suggested that spinal dura mater injury should be avoided during surgery in high-risk patients.

Abstract
PURPOSE To compare the efficacy and safety of high-dose vitamin C plus FOLFOX ± bevacizumab versus FOLFOX ± bevacizumab as first-line treatment in patients with metastatic colorectal cancer (mCRC). PATIENTS AND METHODS Between 2017 and 2019, histologically confirmed patients with mCRC (n = 442) with normal glucose-6-phosphate dehydrogenase status and no prior treatment for metastatic disease were randomized (1:1) into a control (FOLFOX ± bevacizumab) and an experimental [high-dose vitamin C (1.5 g/kg/d, intravenously for 3 hours from D1 to D3) plus FOLFOX ± bevacizumab] group. Randomization was based on the primary tumor location and bevacizumab prescription. RESULTS The progression-free survival (PFS) of the experimental group was not superior to the control group [median PFS, 8.6 vs. 8.3 months; HR, 0.86; 95% confidence interval (CI), 0.70-1.05; P = 0.1]. The objective response rate (ORR) and overall survival (OS) of the experimental and control groups were similar (ORR, 44.3% vs. 42.1%; P = 0.9; median OS, 20.7 vs. 19.7 months; P = 0.7). Grade 3 or higher treatment-related adverse events occurred in 33.5% and 30.3% of patients in the experimental and control groups, respectively. In prespecified subgroup analyses, patients with RAS mutation had significantly longer PFS (median PFS, 9.2 vs. 7.8 months; HR, 0.67; 95% CI, 0.50-0.91; P = 0.01) with vitamin C added to chemotherapy than with chemotherapy only. CONCLUSIONS High-dose vitamin C plus chemotherapy failed to show superior PFS compared with chemotherapy in patients with mCRC as first-line treatment but may be beneficial in patients with mCRC harboring RAS mutation.

Abstract
Titanium (Ti) is a widely used metallic biomaterial in developing orthopedic implants or devices, but it is often encountered with a poor osteogenic response. In this study, the authors report the surface modification of Ti with cobalt (Co)-containing titanium dioxide (TiO2)
coatings by plasma oxidation technique in order to enhance its cellular response. The results were compared between unmodified and surface modified Ti. The scanning electron microscopy (SEM) analysis showed that the surface coating was homogenous and porous throughout the test specimen. Indeed,
the energy-dispersive X-ray spectrometry (EDS) analysis showed that the cobalt was evenly distributed on the Ti surface. It was also observed from the preliminary cell culture studies that the surfacemodified Ti has excellent cell compatibility and has promoted the adhesion and proliferation
of osteoblasts when compared to the unmodified Ti. The present study clearly demonstrated that the Co-containing plasma electrolytic oxidation is an efficient technique for the surface modification of Ti in order to promote its osteogenic response.

Abstract
Objectives: To compare the clinical efficacy of unilateral and bilateral puncture PKP in the treatment of OVCFs and explored whether there is a difference in the efficacy of unilateral and bilateral puncture PKP after surgery. Methods: A total of 98 patients with OVCFs treated by PKP from August 2016 to June 2018 were selected. There were 62 cases in the unilateral puncture group and 36 cases in the bilateral puncture group. The operation time, the amount of bone cement injection, the height of the anterior edge of the vertebral body and the visual analog scale (Visual Analog Scale, VAS) scores before and after the operation were analyzed, and whether the differences between the 2 groups were statistically significant was analyzed. Results: All patients were followed up completely. The operation time and the number of X-ray fluoroscopies of the unilateral puncture group were significantly reduced compared to those of the bilateral group, and the difference was statistically significant (p<0.05). In terms of the bone cement injection volume, the average injection volume of the bilateral group was greater than that of the unilateral group, and the difference was statistically significant (p<0.05); the postoperative VAS scores of the 2 groups of patients were significantly improved, and the difference was statistically significant compared with that before surgery (p<0.05) but that of the unilateral group was not statistically significant compared with that of the bilateral group (p>0.05). The height of the anterior edge of the vertebral body in both groups was significantly improved compared with that before the operation, and the difference was statistically significant (p<0.05). Conclusion: Unilateral and bilateral puncture PKP can achieve good clinical efficacy in the treatment of osteoporotic vertebral compression fractures, but unilateral PKP has the advantages of short operation time and low X-ray exposure.

Abstract
BACKGROUND Hepatic cystic echinococcosis (CE) is an infectious zoonotic parasitic disease, and the insidious onset and slow progression of hepatic CE usually contributes to delayed diagnosis and treatment. Hepatocellular carcinoma (HCC) is the fourth most common malignant tumor. Co-existence of CE and HCC is fairly rare in clinical settings and the association between the two is still not well recognized. We report a case of hepatic CE complicated with HCC which are radically resected and raise some questions worth thinking about.
CASE SUMMARY A 70-year-old man presented with upper abdominal pain. On admission, laboratory data showed that, except for hepatitis B surface antigen positivity, other indicators were normal, including alpha-fetoprotein. Computed tomography of the abdomen revealed a huge polycystic lesion in left liver lobe, without reinforcement after enhanced scanning and sized about 16.9 cm × 12.2 cm, which was considered a type II hydatid cyst. Multiple small solid lesions were also found adjacent to it, and thus it was highly suspected as a malignant tumor. After a multidisciplinary team discussion, the diagnosis of co-occurrence of hepatic CE and HCC was made. According to Romic classification, the case belongs to type IIb, and radical left hemi-hepatectomy was performed. Postoperative pathological examination revealed CE co-existence with well-differentiated HCC, consistent with the preoperative diagnosis.
CONCLUSION With the combination of hepatitis B and obvious extrusion by large hydatid, the HCC risk of a patient might be higher.

Abstract
Background With the mature application of laparoscopy in hepatobiliary surgery, laparoscopic treatment of hepatic cystic echinococcosis (CE) has made certain progress. But, due to the inherent limitations of laparoscopy and the growth characteristics of cystic echinococcosis, distinguishing the boundary between cystic lesion and normal hepatic parenchyma is pivotal importance for successful surgery. Indocyanine green (ICG) fluorescence imaging technology can view the boundary of lesion and normal tissue during the treatment of hepatic cystic echinococcosis. Applied laparoscopy combined with ICG fluorescence imaging technique for hepatic cystic echinococcosis may be an effective surgical strategy. Methods The clinical data contained nine patients with hepatic cystic echinococcosis who underwent laparoscopic surgery with indocyanine green fluorescence imaging technique in authors’ institution from December 2018 to December 2019 were retrospectively analyzed. Indocyanine green was administered intravenously three days prior to surgery. The fluorescence acquisition system for real-time imaging was used during the surgery and the patients were followed up after surgery. Results Of reported nine patients, six are male and the remaining three are female. The average age is (36.4 ± 7.6) years. For all subjects, surgical procedures were performed under laparoscopy with indocyanine green fluorescence system. This technique showed the clear boundary of the hepatic cyst with normal liver parenchyma. Total cystectomy in six patients, subtotal cystectomy in two patients and partial hepatectomy in one patient were performed respectively. The average operation time was 3.8 ± 0.9 h, blood loss 206.0 ± 120.7 ml. Neither blood transfusion nor post-operative complication was experienced. The average abdominal drainage time was 3.4 ± 0.9 days with hospital stay 5.7 ± 2.1 days. During the 6–12 months follow-up period, neither recurrence nor intraperitoneal implantation was found. Conclusions Applied laparoscopy combined with ICG fluorescence imaging technique for hepatic cystic echinococcosis is safe and feasible. Enhanced boundary image can assist surgeons to complete radical resection and reduce complications.

Abstract
BACKGROUND Radical resection is an important treatment method for hepatic echinococcosis. The posterosuperior segments of the liver remain the most challenging region for laparoscopic or robotic hepatectomy.
AIM To demonstrate the safety and preliminary experience of robotic radical resection of cystic and alveolar echinococcosis in posterosuperior liver segments.
METHODS A retrospective analysis was conducted on the clinical data of 5 patients with a median age of 37 years (21-56 years) with cystic and alveolar echinococcosis in difficult liver lesions admitted to two centers from September to December 2019. The surgical methods included total pericystectomy, segmental hepatectomy, or hemihepatectomy.
RESULTS Among the 5 patients, 4 presented with cystic echinococcosis and 1 presented with alveolar echinococcosis, all of whom underwent robotic radical operation successfully without conversion to laparotomy. Total caudate lobectomy was performed in 2 cases, hepatectomy of segment VII in 1 case, total pericystectomy of segment VIII in 1 case, and right hemihepatectomy in 1 case. Operation time was 225 min (175-300 min); blood loss was 100 mL (50-600 mL); and postoperative hospital stay duration was 10 d (5-19 d). The Clavien-Dindo complication grade was I in 4 cases and II in 1 case. No recurrence of echinococcosis was found in any patient at the 3 mo of follow-up.
CONCLUSION Robotic radical surgery for cystic and selected alveolar echinococcosis in posterosuperior liver segments is safe and feasible.

Abstract
Monoclonal gammopathy of renal significance (MGRS) can present with different morphologic features and lead to kidney failure. The Henoch-Schönlein purpura nephritis (HSPN) that cannot be relieved by treatment with glucocorticoid and immunosuppressive agents suggests the presence of monoclonal gammopathy in adult patients. The present study reports on a single case of HSPN associated with IgA-κMGRS. The patient who suffered from recurrent skin purpura for 6 months and nephrotic syndrome for 2 months was admitted to our hospital. Bone marrow biopsy showed monoclonal gammopathy of undetermined significance. Kidney biopsy indicated a Henoch-Schönlein purpura nephritis (HSPN, ISKDC classified as type III) with positive staining with κ-light chain in the glomeruli and renal tubular epithelial cells. Furthermore, skin biopsy showed leukocytoclastic vasculitis and negative staining for Congo red and light chain. Given both the renal and cutaneous involvement, the patient was considered to have HSPN associated with IgA-κMGRS. The patient experienced an exacerbation in his purpura-like lesions and clinical status after treatment with glucocorticoid and immunosuppressive agents. Consequently, the patient was put on a regimen that included dexamethasone (20 mg on the 1st, 4th, 8th, and 11th days of each month, iv) and bortezomib (2.4 mg on the 1st, 4th, 8th, and 11th days of each month, iv). Eight weeks after treatment, he had complete resolution of his cutaneous purpura and his biochemical parameters improved. The latent presence of MGRS in cases of HSPN should be considered in adult patients. Increased cognizance and correct treatment options could improve patient outcomes.

Abstract
Pyoderma gangrenosum (PG) is an uncommon ulcerative cutaneous condition of an unknown etiology and is often associated with immune diseases. However, PG rarely shows visceral involvement, especially in the kidney. A 20-year-old female presented with pedal edema and skin ulceration of both lower limbs. The skin lesion began as an erythematous plaque and then became a blister. She also complained of abdominal distension and a decreasing urine volume. Laboratory data showed high proteinuria, hypoalbuminemia and hyperlipidemia. Her skin and kidney were biopsied. The pathological results indicated PG and immunoglobulin A (IgA) nephropathy. The patient was finally cured with prednisolone in combination with cyclosporine A (CsA).

Abstract
An efficient and convenient palladium-catalyzed direct intermolecular silylation of C(sp2)-H bonds by using disilanes as the silicon source with the assistance of a readily removable bidentate directing group is reported. This strategy provided a regio- and stereoselective protocol for exclusive synthesis of Z-vinylsilanes with reasonable to excellent yields and good functional group compatibility. Silylation of the isolated palladacycle intermediate revealed the Z-stereoselective pathway. Moreover, the practicality and effectiveness of this method were illustrated by a gram-scale experiment and further functionalization of the silylation product.

Abstract
Salvianolic acid B (SAB) is one the major phytocomponents of Radix Salvia miltiorrhiza and exhibit numerous health promoting properties. The objective of the current study was to examine whether SAB exerts a renoprotective effect by attenuating oxidative stress and inflammatory response through activating phosphatidylinositol 3-kinase/serine-threonine kinase B (PI3K/Akt) signaling pathway in a renal ischemic reperfusion rat model. Forty Sprague-Dawley male rats (250–300 g) were obtained and split into four groups with ten rats in each group. The right kidney of all rats was removed (nephrectomy). The rats of the Control group received only saline (occlusion) and served as a sham control group, whereas rats subjected to ischemic reperfusion (IR) insult by clamping the left renal artery served as a postitive control group. The other 2 groups of rats were pretreated with SAB (20 and 40 mg·kg-1·day-1) for 7 days prior IR induction and served as treatment groups (SAB 20+IR; SAB 40+IR). Renal markers creatinine (Cr) and blood urea nitrogen (BUN) were significantly lower in the groups that received SAB. Pretreatment with SAB appears to attenuate oxidative stress by suppressing the production of lipid peroxidation products like malondialdehyde as well as elevating antioxidant activity. The concentration of inflammatory markers and neutrophil infiltration (myeloperoxidase) were significantly decreased. Meanwhile, PI3K protein expression and pAkt/Akt ratio were significantly upregulated upon supplementation with SAB, indicating its renoprotective activity. Taken together, these results indicate that SAB can therapeutically alleviate oxidative stress and inflammatory process via modulating PI3K/Akt signaling pathway and probably ameliorate renal function and thus act as a renoprotective agent.

Abstract
MiR-200b, a member of the microRNA-200 family, has been identified to be capable of suppressing glioma cell growth through targeting CREB1 or CD133. However, whether miR-200b affects the biological behavior (proliferation, invasion, and migration) of glioma cells is poorly understood. The aim of this study was to evaluate the effect of miR-200b on the biological behavior of glioma cells in vitro. MiRNA-200b mimics, miRNA-200b inhibitor, and mimic control were transfected into conventionally cultured glioma U251 cells, followed by measuring the expression of miR-200b and CD133 in transfected cells by RT-PCR; effect of miR-200b on CD133 mRNA 3'-UTR luciferase activity by luciferase reporter assay; proliferation activity of transfected U251 cells by MTT method; and changes in U251 cell invasion and migration by Transwell method after transfection. Compared to that in the miRNA-200b inhibitor, mimic control, and blank control groups, miRNA-200b expression was significantly increased and CD133 mRNA expression was significantly decreased in the mimic miRNA-200b group in a time-dependent manner (P < 0.05). Meanwhile, dual luciferase reporter assay showed that miR-200b could inhibit CD133 activity through binding to the 3'-UTR of CD133 mRNA (P < 0.05). Furthermore, the proliferation activity and invasion and migration abilities of U251 cells transfected with miRNA-200b mimic were significantly decreased (P < 0.05). In conclusion, overexpression of miR-200b inhibited the proliferation, invasion, and migration of glioma cells possibly through targeting CD133.

Abstract
AIM: To evaluate the therapeutic effects of bone marrow-derived mesenchymal stem cells (BMSCs) with human urokinase-type plasminogen activator (uPA) on liver fibrosis, and to investigate the mechanism of gene therapy.
METHODS: BMSCs transfected with adenovirus-mediated human urokinase plasminogen activator (Ad-uPA) were transplanted into rats with CCl4-induced liver fibrosis. All rats were sacrificed after 8 wk, and their serum and liver tissue were collected for biochemical, histopathologic, and molecular analyzes. The degree of liver fibrosis was assessed by hematoxylin and eosin or Masson’s staining. Western blot and quantitative reverse transcription-polymerase chain reaction were used to determine protein and mRNA expression levels.
RESULTS: Serum levels of alanine aminotransferase, aminotransferase, total bilirubin, hyaluronic acid, laminin, and procollagen type III were markedly decreased, whereas the levels of serum albumin were increased by uPA gene modified BMSCs treatment. Histopathology revealed that chronic CCl4-treatment resulted in significant fibrosis while uPA gene modified BMSCs treatment significantly reversed fibrosis. By quantitatively analysing the fibrosis area of liver tissue using Masson staining in different groups of animals, we found that model animals with CCl4-induced liver fibrosis had the largest fibrotic area (16.69% ± 1.30%), while fibrotic area was significantly decreased by BMSCs treatment (12.38% ± 2.27%) and was further reduced by uPA-BMSCs treatment (8.31% ± 1.21%). Both protein and mRNA expression of β-catenin, Wnt4 and Wnt5a was down-regulated in liver tissues following uPA gene modified BMSCs treatment when compared with the model animals.
CONCLUSION: Transplantation of uPA gene modified BMSCs suppressed liver fibrosis and ameliorated liver function and may be a new approach to treating liver fibrosis. Furthermore, treatment with uPA gene modified BMSCs also resulted in a decrease in expression of molecules of the Wnt signaling pathway.

Abstract
This study was designed to observe the comprehensive efficacy of traditional Chinese medicine (TCM) combined with interferon in the treatment of chronic hepatitis C (CHC), compare this combined therapy with interferon therapy alone and investigate its possible mechanism to provide a basis for the development of an integrated traditional Chinese and Western medicine for the treatment of CHC. According to patient contraindications for antiviral treatment, patients who were suitable for interferon therapy and willing to use TCM were enrolled as combined traditional Chinese and Western medicine group, and 21 CHC patients were selected as Western medicine control group; patients who had contraindications for antiviral treatment were included in the TCM group. The three groups of patients were all diagnosed with positive hepatitis C virus - ribose nucleic acid (HCV-RNA). The treatment course lasted for one year and the patients were followed up for 12 months. Patients demographic data, course of disease, chronic liver disease questionnaire (CLDQ), genetic typing, biochemical indexes, HCV-RNA and side effects were compared between the groups. The efficacy, incidence of side effects and improvement in quality of life were analyzed in each group. Results showed that the combination of TCM and interferon could protect liver, reduce side effects and also improve quality of life of the patients, while the antiviral activity of TCM alone was not obvious.

Abstract
BACKGROUND Jatropha curcus is a good candidate plant for biodiesel production in tropical and subtropical regions. However, J. curcus is susceptible to the geminivirus Indian cassava mosaic virus (ICMV), and frequent viral disease outbreaks severely limit productivity. Therefore the development of J. curcus to carry on durable virus resistance remains crucial and poses a major biotechnological challenge. RESULTS We generated transgenic J. curcus plants expressing a hairpin, double-stranded (ds) RNA with sequences homologous to five key genes of ICMV-Dha strain DNA-A, which silences sequence-related viral genes thereby conferring ICMV resistance. Two rounds of virus inoculation were conducted via vacuum infiltration of ICMV-Dha. The durability and heritability of resistance conferred by the dsRNA was further tested to ascertain that T1 progeny transgenic plants were resistant to the ICMV-SG strain, which shared 94.5% nucleotides identity with the ICMV-Dha strain. Quantitative PCR analysis showed that resistant transgenic lines had no detectable virus. CONCLUSIONS In this study we developed transgenic J. curcus plants to include a resistance to prevailing geminiviruses in Asia. These virus-resistant transgenic J. curcus plants can be used in various Jatropha breeding programs.

Abstract
Liver fibrosis, a reversible pathological condition occurring after chronic liver injury, is closely associated with the activation and proliferation of hepatic stellate cells (HSCs). Several studies have demonstrated that the Wnt signaling pathway is involved in the activation of HSCs, and then contributes to the occurrence and development of liver fibrosis. Thus, the Wnt signaling pathway and HSCs are considered to be the valid targets for the treatment of liver fibrosis. In recent years, domestic and international scholars have carried on many studies on the regulation of the Wnt signaling pathway and HSCs, trying to find out effective antifibrotic therapies. A large number of studies have shown that regulating HSCs can play a positive role in the treatment of liver fibrosis through the Wnt signaling pathway. On the basis of the relationship among the Wnt signaling pathway, HSCs and liver fibrosis, this review mainly summarizes the latest progress in the study of strategies for regulating HSCs through the Wnt signaling pathway and discusses the implications for the treatment of liver fibrosis.

Abstract
Fatty acid desaturases exist in all living organisms and play important roles in many different biologic processes, such as fatty acid metabolism, lipid biosynthetic processes, and pheromone biosynthetic processes. Using the available silkworm genome sequence, we identified 14 candidate fatty acid desaturase genes. Eleven genes contain 3 conserved histidine cluster motifs and 4 transmembrane domains, but their N-terminal residues exhibit obvious diversity. Phylogenetic analysis revealed that there are 6 groups; Bmdesat1 and Bmdesat5-8 were clustered into group 2, which is involved in Δ11 desaturation activity, and Bmdesat3-4 were grouped in group 1, which is involved in Δ9 desaturation activity. Twelve of the 14 genes have expressed sequence tag evidence. Microarray data and reverse transcription polymerase chain reaction analysis demonstrated that Bmdesat3-4 and Bmdesat10 were expressed from the larval to moth stages and in multiple tissues on day 3 of 5th instar larvae. Bmdesat9, Bmdesat11, and Bmdesat14 were expressed during the pupal and late-embryonic stage, suggesting that they may take part in fatty acid metabolism to provide energy. These results provide some insights into the functions of individual fatty acid desaturases in silkworm.

Abstract
Glucocorticoids (GCs) resistance is frequently encountered in children with acute lymphoblastic leukemia (ALL), especially in T-ALL, which usually results in failure of treatment. To find new agent to overcome GC resistance of ALL is an urgent problem. Here we investigated potential effect of anisomycin on GC-resistant T-ALL CEM-C1 cells and explored involved molecular mechanisms. Dramatic growth inhibition and apoptosis in GC resistant CEM-C1 cells and GC-sensitive CEM-C7 cells induced by anisomycin were observed, which presented in a concentration- and time-dependent manner. Correspondingly, anisomycin induced cleaved caspase-3 and up-regulation of pro-apoptotic proteins (BimEL and Bad), meanwhile down-regulation of anti-apoptotic proteins (Mcl-1 and Bcl-2), both in a dose- and time-dependent manner in GC resistant CEM-C1 cells. Anisomycin also induced cell cycle arrest at G0/G1 phase in CEM-C1 cells through increasing expressions of p21 and p27, and attenuating the expression of cyclinA. The rapid up-regulation of phosphorylated mitogen-activated protein kinases (MAPKs) p38 and Jun N-terminal kinase (JNK) were observed after CEM-C1 cells were incubated with anisomycin. The activation of p38 and JNK could be blocked by respective inhibitors (SB203580 for p38 and SP600125 for JNK) accompanied with the inhibition of apoptosis and changes of apoptosis associated proteins in CEM-C1 cells. These results suggested that anisomycin induced apoptosis of CEM-C1 cells via activation of p38 and JNK, and might be an attractive new agent for treatment of GC-resistant ALL.

Abstract
Based on the TM and ETM remotely sensed images of Yangtze Estuary in 1987, 1995, 2000, and 2006, and by using RS, GIS, and mathematical statistical methods, this paper analyzed the dynamic changes of land use and land cover in different reclamation zones of the estuary. In terms of relative area occupied by each land use type, grassland showed significant spatial differences (P < 0.05) among the reclamation zones, while greenhouse land and paddy field showed significant temporal differences (P < 0.05). After eliminating the factor reclamation time, there was no significant difference in the land use diversity index among the reclamation zones. In terms of land use change rates, no significant spatial difference was observed among the reclamation zones, while greenhouse land and built-up area showed significant temporal differences. In terms of land use intensity and transformation direction, different reclamation zones had no significant differences. The land use dynamic changes in different reclamation zones of the estuary were mainly affected by reclamation time.

Abstract
OBJECTIVE Cardiovascular (CV) disease (CVD) is the single most important cause of death among Chinese dialysis patients, accounting for 51% of overall mortality. The study was performed to investigate the prevalence and the spectrum of CVD in Chinese chronic kidney disease (CKD) patients. METHODS The multicenter Chinese cohort study examined 1239 CKD patients from 7 main medical centers (distributed in 5 regions of China) who were hospitalized between 2002 and 2003. RESULTS (1) The most prevalent pathological form of CVD was left ventricular (LV) hypertrophy (LVH), accounting for 58.5% of total patients. The prevalence of coronary artery disease (CAD), congestive heart failure (CHF), and cerebrovascular accidents (CVA) was 16.5%, 27.7% and 5.6%, separately. (2) The cohort with minor renal dysfunction (stage 2-3) had higher prevalence of CAD (5.9%) and CVA (1.0%) compared with general population in the same regions. Up to 41.2% of minor CKD patients were complicated with LVH, and 13.8% of them had clinical evidence of CHF. The prevalence of CAD, LVH and CHF increased as glomerular filtration decline. (3) The prevalence of CAD (20.0%) was much lower and the prevalence of CVA (5.4%) was higher in Chinese dialysis patients than that in American dialysis population. There was significant geographical variations in CAD prevalence, but it was not different between genders. CONCLUSION The CV risk is significantly increased in patients with CKD. Even minor CKD has a major impact on the CV risk. The prevalence of CAD in Chinese dialysis patients is markedly lower than that in American dialysis population.

Abstract
One 63-year-old woman, who presented with cholestatic jaundice due to common bile duct compression produced by primary retroperitoneal fibrosis, is studied. The patient was operated six years ago because of hydronephrosis, when the disease was first diagnosed. Magnetic resonance cholangiopancreatography (MRCP) revealed the presence of extrahepatic bile duct obstruction, which once was considered to be pathognomonic of pancreatic cancer. CT-scan demonstrated the change of retroperitoneal fibrosis around left kidney, atrophy of right kidney, and obstruction of extrahepatic bile duct (pancreatic head). An explorative laparotomy was performed, and the retroperitoneum and pancreas were grayish-white and hard, the fibrotic pancreatic head compressed the common bile duct. Bile duct stricture was managed by Rouxen-Y hepatocholangio-jejunostomy. To the best of our knowledge, few similar cases of retroperitoneal fibrosis have been reported.

Abstract
Fifty-six patients with de novo acute myeloid leukemia M4/M5 subtypes were studied for rearrangements of the mixed lineage leukemia gene, MLL (also called HRX, Htrx-1, or ALL-1). Ten patients (18%) showed rearrangements of the MLL gene, 9 in a major breakpoint cluster region within a centromeric 8.3-kb BamHI fragment, whereas rearrangement in one patient was the result of a direct tandem duplication of exons 2-6 of MLL. Analysis of sequences at the duplication junction revealed that the points of MLL fusion within introns 6 and 1 both lie within Alu elements. This suggests the involvement of Alu repeat mediated homologous recombination in MLL self fusion. For the 10 rearranged samples, cytogenetics analysis revealed a normal karyotype in 3, and 3 had abnormalities other than 11q23. Survival analysis of patients revealed no difference between those with rearrangement of MLL and those showing the germ-line configuration.
