Abstract
BACKGROUND Observational studies have suggested that depression is associated with sarcopenia. However, the causal relationship between depression and sarcopenia remains unclear.
AIM To investigate the causal relationship between depression and sarcopenia.
METHODS We performed a Mendelian randomization (MR) analysis to identify the bidirectional relationship between depression and sarcopenia-related traits. Summary-level data and independent variants used as instrumental variables came from large genome-wide association studies of depression (414055 cases and 892299 controls), of appendicular lean mass (ALM, 450243 participants), and of hand grip strength (exposure: 360000 participants; outcome: 334925 participants).
RESULTS We identified a negative association of depression with lower ALM [odds ratio (OR): 0.932, 95% confidence interval (95%CI): 0.889-0.979, P = 0.005]. In the reverse MR analysis, we also observed an inverse association of hand grip strength with depression (OR: 0.200, 95%CI: 0.108-0.370, P < 0.001). Similar results were obtained in sensitivity analyses.
CONCLUSION Depression was causally related to decreased muscle mass, and declined muscle strength might lead to a higher risk of depression.

Abstract
DMRT, a gene family related to sexual determination, encodes a large group of transcription factors (DMRTs) with the double-sex and mab-3 (DM) domain (except for DMRT8), which is able to bind to and regulate DNAs. Current studies have shown that the DMRT gene family plays a critical role in the development of sexual organs (such as gender differentiation, gonadal development, germ cell development, etc.) as well as extrasexual organs (such as musculocartilage development, nervous system development, etc.). Additionally, it has been suggested that DMRTs may be involved in the cancer development and progression (such as prostate cancer, breast cancer, lung cancer, etc.). This review summarizes the research progress about the mammalian DMRTs' structure, function and its critical role in cancer development, progression and therapy (mainly in human and mice), which suggests that DMRT gene could be a candidate gene in the study of tumor formation and therapeutic strategy.

Abstract
Although livestock manure serves as an effective source of nutrients for agricultural purposes, it also causes an obvious risk of contamination of heavy metals and pathogens in soil. Soil microorganisms are always considered a sensitive indicator for the change in soil quality. However, knowledge of the effects of cow manure application on soil microbial community is still scarce. Therefore, the characteristics of the soil microbial community and its influencing factors in the farmland with cow manure application were studied using dilution plate counting and high-throughput sequencing. The results showed that the β diversity of the soil microbial community exhibited a significant difference between the cow manure application site and control site. The application of cow manure increased the relative abundance of Proteobacteria but decreased the relative abundances of Actinobacteria and Gemmatimonadetes. Furthermore, the cow manure application significantly changed the relative abundances of Sphingomonas,PLTA13, MSB-4B10, Halomonas, CCD24, Gaiella, Arthrobacter, Bacillus, and Entotheonellaceae. Both the content of soil water and actinomycete numbers were the important influencing factors of soil microbial community composition in the farmland with cow manure application. The cow manure application increased the relative abundance of pathogenic bacteria including Pseudomonas, Clostridium, and Streptococcus, which may have resulted in potential risks of pathogenic contamination for soil quality. The findings of this study are useful for understanding the effects of cow manure application on soil quality in farmland.

Abstract
Objective: To investigate the clinicopathological characteristics of reactive epithelial hyperplasia and dysplasia in the stomach, as well as the clinical value of mucin special staining and proliferating cell nuclear antigen (Ki-67) in distinguishing the two gastric lesions. Methods: The clinical pathological data of 63 patients with gastric reactive epithelial hyperplasia, 54 patients with low-grade dysplasia, and 63 patients with high-grade dysplasia diagnosed from May 2018 to May 2021 in Beijing Chaoyang Hospital, Capital Medical University, Beijing, China were analyzed. Alcian blue periodic acid Schiff (AB-PAS) and Ki-67 staining were performed to examine the mucin staining pattern, number of Ki-67 positive cells, Ki-67 staining patterns in the three groups of lesions, and histopathologic characteristics. Results: The positive rates of AB-PAS in the reactive epithelial hyperplasia and gastric dysplasia groups were 87.3%(55/63) and 10.3%(12/117), respectively. The expression of AB-PAS in the reactive epithelial hyperplasia was gradually increased from the base to the surface of the epithelium. In low-grade dysplasia and high-grade dysplasia, there was no mucin present in the dysplasia epithelium. The difference between the two groups was statistically significant (P<0.01). The positive rate of Ki-67 in the epithelial reactive hyperplasia (>10%) was 81.0% (51/63), and the positive cells were mainly located in the neck and middle parts of the mucosal glands (58/63, 92.1%). In the low-grade dysplasia group, the positive rate of Ki-67 (>10%) was 90.7%(49/54); the positive cells were mainly located in the upper mucosa (33/54, 61.1%), showing a banded distribution pattern; in the high-grade dysplasia group, the positive rate (>10%) was 95.2%(60/63), and the positive cells were mainly located in the whole mucosa (49/63, 77.8%), showing a diffuse/diffuse scattered distribution pattern. The three groups had statistically different rates and distribution patterns of Ki-67 expression (P<0.01). Conclusion: The gastric epithelial reactive hyperplasia and dysplasia can be differentiated using clinicopathological features, AB-PAS staining and Ki-67 expression pattern.

Abstract
Rubiaceae is the fourth largest and a taxonomically complex family of angiosperms. Many species in this family harbor low reproductive isolation and frequently exhibit inconsistent phenotypic characteristics. Therefore, taxonomic classification and their phylogenetic relationships in the Rubiaceae family is challenging, especially in the genus Leptodermis. Considering the low taxonomic confusion and wide distribution, Leptodermis oblonga is selected as a representative Leptodermis for genome sequencing. The assemblies resulted in 497 Mbp nuclear and 155,100 bp chloroplast genomes, respectively. Using the nuclear genome as a reference, SNPs were called from 37 Leptodermis species or varieties. The phylogenetic tree based on SNPs exhibited high resolution for species delimitation of the complex and well-resolved phylogenetic relationships in the genus. Moreover, 28,987 genes were predicted in the nuclear genome and used for comparative genomics study. As the first chromosomal-level genome of the subfamily Rubioideae in Rubiaceae, it will provide fruitfully evolutionary understanding in the family.

Abstract
Betanin and curcumin hold promise as natural colorants and antioxidants for food purposes due to their anti-hypertensive, anti-inflammation, and anti-tumor effects. However, the thermal stability and bioavailability of betanin and curcumin still need improvement. Here, we fabricated sugar beet pectin-bovine serum albumin nanoparticles (SBNPs) with a mean particle size of 180 ± 5.2 nm through a genipin cross-linking strategy to stabilize a type of Pickering water-in-oil-in-water (W/O/W) emulsion and co-encapsulated betanin and curcumin. First, the W1/O emulsion was homogenized with gelatin (the gelling agent) in the water phase and polyglycerol polyricinoleate (a lipophilic surfactant) in the oil phase. Later, W1/O was homogenized with another water phase containing SBNPs. The microstructure of the emulsion was regulated by the particle concentration (c) and W1/O volume fraction (Φ), especially the gel-like high internal phase emulsions were formed at the Φ up to 70%. In this case, betanin was encapsulated in the internal water phase (encapsulation efficiency = 65.3%), whereas curcumin was in the medium-chain triglyceride (encapsulation efficiency = 84.1%). Meanwhile, the shelf stability of betanin and curcumin was improved. Furthermore, the stability of bioactive compounds was potentiated by an emulsion gel in simulated gastrointestinal digestion, resulting in higher bioaccessibility. The aforementioned results suggest that SBNP-stabilized Pickering W/O/W emulsions could be a potential alternative to co-encapsulate betanin and curcumin with enhancement of shelf stability and bioaccessibility.

Abstract
Objective: To assess the relationship between body mass index (BMI) and death risk of cardiovascular disease (CVD) in rural male population. Methods: 22 282 men aged 40 years older in Tanghe county and Fenghuang county from the cohort of the "Prospective Study on Adult Behavior and Health Risk Factors in China" were selected as subjects of this study. Cox regression model was used to calculate the hazard ratios (HRs) of the death of CVD during the follow-up period with different BMI groups at baseline. Results: The average follow-up period in the two counties was (19.1±8.7) years and 10 828 (48.6%) people died during the follow-up period. 4 504 deaths were attributed to CVD. Among the deaths of CVD, 1 279 cases died of ischemic heart disease (IHD), ischemic stroke (IS) died in 1 201, cases died of died of 1 317 hemorrhagic stroke (HS), other 707 cases. Compared to population with BMI<18 kg/m(2), Cox regression model (adjusting factors of region, age, nationality, education level, occupation, smoking, drinking, blood pressure, blood pressure, etc.) showed that people with BMI between 20-22 kg/m(2) had the lowest risk of CVD death (HR=0.95, 95%CI: 0.83-1.09). But the difference was not statistically significant among each BMI group (P>0.05). The risk of IHD death was the lowest in the population with BMI between 20-22 kg/m(2) (P<0.05) (HR=0.64, 95%CI: 0.52-0.80). There was no statistically significant difference between the risk of IHD death in the population with BMI≥24 kg/m(2) and that in the population with BMI<18 kg/m(2) (P>0.05). There was no statistically significant difference between the risk of IS death and BMI (P>0.05). The death risk of HS in the population with BMI between 18-24 kg/m(2) was higher than that in the population with BMI<18 kg/m(2) (P<0.05). The death risk of the population with BMI between 26-28 kg/m(2) was the highest (HR=1.88, 95%CI:1.18-2.99). Conclusions: The mortality risk of CVD and IHD was the lowest in lean or normal weight group, and HS was higher in overweight group. Maintaining a reasonable weight can reduce the risk of death in patients with CVD.

Abstract
Background MYC transcriptional factors are members of the bHLH (basic helix-loop-helix) superfamily, and play important roles in plant growth and development. Recent studies have revealed that some MYCs are involved in the crosstalk between Jasmonic acid regulatory pathway and light signaling in Arabidopsis, but such kinds of studies are rare in wheat, especially in photo-thermo-sensitive genic male sterile (PTGMS) wheat line. Results 27 non-redundant MYC gene copies, which belonged to 11 TaMYC genes, were identified in the whole genome of wheat (Chinese Spring). These gene copies were distributed on 13 different chromosomes, respectively. Based on the results of phylogenetic analysis, 27 TaMYC gene copies were clustered into group I, group III, and group IV. The identified TaMYC genes copies contained different numbers of light, stress, and hormone-responsive regulatory elements in their 1500 base pair promoter regions. Besides, we found that TaMYC3 was expressed highly in stem, TaMYC5 and TaMYC9 were expressed specially in glume, and the rest of TaMYC genes were expressed in all tissues (root, stem, leaf, pistil, stamen, and glume) of the PTGMS line BS366. Moreover, we found that TaMYC3, TaMYC7, TaMYC9, and TaMYC10 were highly sensitive to methyl jasmonate (MeJA), and other TaMYC genes responded at different levels. Furthermore, we confirmed the expression profiles of TaMYC family members under different light quality and plant hormone stimuli, and abiotic stresses. Finally, we predicted the wheat microRNAs that could interact with TaMYC family members, and built up a network to show their integrative relationships. Conclusions This study analyzed the size and composition of the MYC gene family in wheat, and investigated stress-responsive and light quality induced expression profiles of each TaMYC gene in the PTGMS wheat line BS366. In conclusion, we obtained lots of important information of TaMYC family, and the results of this study was supposed to contribute novel insights and gene and microRNA resources for wheat breeding, especially for the improvement of PTGMS wheat lines.

Abstract
Background: An aura is usually considered to be the initial clinical sign of a seizure. The types of abnormal neuron activities (i.e., localized and generalized firing) play an important role in the diagnosis of epilepsy. The goal of this study was to investigate the types of auras and its correlation with the localization and treatment of epilepsy. Methods: The 426 epileptic patients with auras from a single center were reviewed with reference to International League Against Epilepsy (ILAE, 1981) classification; the clinical manifestations and incidence of auras were analyzed in this retrospective study, as well as the results of electroencephalogram (EEG), brain magnetic resonance imaging (MRI) and the treatment methods. Results: Among the 426 epileptic patients, six different types of auras were defined, including autonomic auras, sensory auras, mental and affective auras, aura as vertigo, cognitive auras, and unspeakable feelings. Duration of auras ranged from 2 s to 7 min; the median duration of auras was 64.2 s. Abnormal EEG was observed in 297 (69.72%) patients. Moreover, abnormal brain MRI was observed in 125 (29.34%) patients. Nineteen (4.46%) epilepsy patients with auras underwent both surgeries and antiepileptic drugs (AEDs) while others were treated only with AEDs. Conclusions: This study suggested that auras played an important role in the diagnosis, classification, and localization of epilepsy. Epileptic aura could help differentiate partial seizure from generalized seizure.

Abstract
NLRC5 plays an important role in the innate immunity and cellular immunity in many species, but the regulatory mechanism of NLRC5 expression in chickens remains unclear. In this study, a series of deletion fragments of the NLRC5 promoter region were constructed and dual-luciferase assay was performed. Then, we detected the SNP in the core region and its function. Important transcriptional regulatory elements were predicted and identified. Methylation of CpG islands was measured. The results revealed that the two core regions of -4372 to -3756 and -2925 to -2265 in the NLRC5 promoter were essential for NLRC5 mRNA expression in which a SNP (A/G), located at -2470, was found to have an effect on the transcriptional activity. Also, the STAT1 element in the second core region of the NLRC5 promoter was identified to bind with the STAT1 transcription factor, which was necessary for the transcriptional activity. In addition, many other elements in the NLRC5 promoter, including YY1 and CEBP, may contribute significantly to the expression activity of NLRC5. Moreover, two CpG islands were searched. Part of one was located in the first core region, which suggests that epigenetic modification may regulate the activity of the first promoter region, and the other was mostly in an unmethylated state. Collectively, these results suggest the complex regulation of NLRC5 expression includes SNPs, transcription factors and methylation.

Abstract
OBJECTIVE To analyze the relationship between N-nitrosodimethylamine(NDMA)and the risk of digestive tract cancers. METHODS The papers about the relationship between NDMA and the risk of digestive tract cancers published from 1980 to 2012 were retrieved following databases: Chinese BioMedical Literature Database(CBM), the Chinese Journal Full-text Database(CNKI), Wanfang Database, PubMed and EBSCO. The fix and random effect model was used and statistical analyses were conducted by using RevMan 5.1 software. RESULTS Thirteen papers were found, in which 7 about digestive tract cancers were used in this Meta analysis. The NDMA had significant positive effect on the incidence of digestive tract cancers(RR=1.12, 95% CI: 1.03-1.21). The relationship between NDMA and esophageal cancer was not significant(RR=1.18, 95%CI: 0.98-1.41)but NDMA could increase the risk of gastric cancer(RR=1.08, 95% CI: 1.00-1.18). For the subtypes of esophageal and gastric cancer, NDMA had positive relationship with esophageal squamous cell carcinoma(RR=1.72, 95% CI: 1.01-2.96), but had no significant relationship with esophageal adenocarcinoma, cardiac carcinoma and gastric adenocarcinoma. CONCLUSION The population-based cohort studies have showed that the NDMA could significantly increase the risk of digestive tract cancers, but the effects differed with subtypes of esophageal and gastric cancer. However, it is necessary to collect more evidence due to the limited studies and obvious differences in the study design, sampling and exposure measurement of these cohort studies.

Abstract
Background Experimental data suggest that mitochondria is involved in tumorigenesis. However, little is known about the qualitative and quantitative changes of mtDNA in colorectal cancer tissues. We therefore conducted possible correlations of the mitochondrial DNA (mtDNA) copy number in colorectal cancer (CRC) with clinical and pathological findings and CRC prognosis. Methods mtDNA copy numbers in CRC cancer tissue and adjacent non-cancerous tissue samples were measured using quantitative real-time polymerase chain reaction analyses from 60 patients admitted to our hospital. We examined the correlation of mtDNA copy numbers and clinicopathologic parameters of CRC patients. The correlation between mtDNA copy number and three-year survival was analyzed. Results The mtDNA copy number was lower in CRC tissue compared with the corresponding non-cancerous colorectal tissue (mean: 108.60 ± 20.11 vs. 153.68 ± 25.72) and was significantly correlated with lymph-node metastasis. Patients with a lower mtDNA copy number tended to have lower 3-year survival than patients with a higher mtDNA copy number assessed by Kaplan–Meier curves, but the correlation was not significant (overall survival, 63.0 vs 83%). Conclusions These results suggest that a reduced copy number of mtDNA is correlated with malignant potential in CRC.

Abstract
Hemoglobin (Hb) is the major protein component of erythrocytes in animals with red blood, although it can serve additional functions beyond the transport of oxygen. The blood clam (Tegillarca granosa) is one of the few mollusks that has Hb, although the structure and function of molluskan Hbs remain unclear. We characterized two unique and highly compartmentalized blood clam hemoglobin genes, Tg-HbIIA and Tg-HbIIB, at the molecular level. The full-length cDNA of Tg-HbIIA was 731 bp with a 450-bp open reading frame encoding 150 amino acids; that of Tg-HbIIB was 698 bp, with a 456-bp open reading frame encoding 152 amino acids. Their intronic regions were amplified by PCR. The two genes showed the typical 2 intron/3 exon organization found in T. granosa. The 3-D structures of the three blood clam Tg-Hbs were predicted using the SWISS-MODEL Protein Modeling Server, and a phylogenetic analysis was conducted to investigate its evolution. As quantified by qRT-PCR, the expression levels of Tg-HbIIA and Tg-HbIIB were significantly upregulated upon challenge by Vibrio parahaemolyticus, lipopolysaccharides, and peptidoglycans. Three Hb isoforms, Tg-HbI, Tg-HbIIA, and Tg-HbIIB, were found. Specific structures and evolutionary features were found in these molluskan Hb genes. Challenge experiments indicated that Tg-Hbs are involved in immune defense responses against bacterial infection and bacterial pathogenic factors. As this is the first functional research on Hb genes in the blood clam, our findings provide new insight into the innate immune defense mechanisms of T. granosa.

Abstract
Membrane proteins can be investigated at various structural levels, including the topological structure, the high-resolution three-dimensional structure, and the organization and assembly of membrane protein complexes. Gene fusion technology makes it possible to insert a polynucleotide encoding a protein or polypeptide tag into the gene encoding a membrane protein of interest. Resultant recombinant proteins may possess the functions of the original membrane proteins, together with the biochemical properties of the imported fusion tag, greatly enhancing functional and structural studies of membrane proteins. In this article, the latest literature is reviewed in relation to types, applications, strategies, and approaches to fusion tag technology for structural investigations of membrane proteins.

Abstract
Recent findings of linear carbon-atom chains (C-chains) inside carbon nanotubes have stimulated considerable interest. In this work, molecular dynamics (MD) simulation and an elastic string-elastic shell model is adopted to study radial pressure-induced buckling of single-walled carbon nanotubes (SWCNT) filled with a C-chain. The continuum model predicts that the C-chain increases critical buckling pressure considerably (about 40%-160%) for SWCNTs of diameters ranging from 0.68 to 0.72 nm, in reasonable quantitative agreement with the prediction of MD simulation. In particular, the MD simulation confirms that the originally circular cross section of filled SWNTs becomes elliptical after buckling, as predicted by the continuum model.

Abstract
OBJECTIVE To analyse the neointimal coverage of sirolimus-eluting stent (SES) and bare-metal stent (BMS) visualised in vivo by optical coherence tomography (OCT). METHODS OCT images were obtained in 26 coronary vessels of 24 patients at 5-93 months after SES or BMS deployment. The short-term BMS group (BMS1) consisted of eight BMS in seven patients at 5-10 months of follow-up, the long-term BMS group (BMS2) consisted of six BMS in six patients at 23-93 months of follow-up, and the SES group (SES) consisted of 13 SES in 10 patients at 6-12 months of follow-up. The strut apposition, strut coverage and mean maximal and minimal neointimal thicknesses (NIT) for both BMS groups and SES were compared. RESULTS OCT images were acquired successfully. Significant differences between completely apposed and malapposed stent struts (p<0.0001) and between covered and uncovered stent struts (p<0.0001) were found among the three groups. The mean maximal and minimal NIT in the SES group were all significantly less than those of the BMS1 or BMS2 group, the minimal NIT in the BMS1 group was significantly less than that of the BMS2 but the mean maximal NIT was no significant difference between the BMS1 and BMS2 groups. In an open bifurcation artery, 19 struts visualised by OCT had no discernible coverage or were surrounded by either thrombus or a thick tissue layer. CONCLUSIONS OCT imaging can clearly visualise stent apposition and neointimal coverage of stent struts. Incomplete strut apposition and lack of strut coverage occurred with a significantly higher frequency in SES than in BMS. These findings may explain the occurrence of late thrombosis in SES. Optical coherence tomography (OCT) is the optical analogue to ultrasound, measuring the back-reflection of infrared light instead of sound waves. The greatest advantage of OCT is its high resolution, which exceeds that of any currently available in vivo imaging technology. The resolution of catheter-based systems is in the range of 10-20 microm. Furthermore, resolutions as high as 4 microm have been achieved ex vivo with more sophisticated techniques that may be applicable to future catheter-based approaches. The main components of various atheromatous plaques can be identified in OCT images, and have been validated in a histology-controlled study. Several studies have demonstrated the feasibility of OCT imaging in patients undergoing percutaneous coronary intervention (PCI). The aim of the present study was to use OCT to analyse the neointimal coverage of sirolimus-eluting stents (SES), compared with that of bare-metal stents (BMS).

Abstract
The study was purposed to investigate the polymorphism of killer cell immunoglobulin-like receptor (KIR) gene of the patients with leukemia and to explore the correlation between the KIR gene and susceptibility of leukemia. The KIR genotype of 50 patients with leukemia and 60 healthy controls in northern. Hans were analyzed by PCR-SSP. The results indicated that the present known 18 KIR genes were detected and identified. The frequencies of KIR 3DL3, 3DL2 and 2DL4 were 100% in all subjects, with the most frequent genotype KIR 3DP1 (0.86) followed by 2DP1, 2DL3, 3DL1, 2DL1, 3DS1, 2DL5, 2DS4, 2DS2, 1D, 2DS5, 2DL2, 2DS1, 2DS3 and 3DP1v in leukemia successively. Compared with the control, the KIR 3DL1 (0.60) and 2DL1 (0.57) were significantly lower in the leukemia patient group than that in the control group (1.00) (P < 0.01). It is concluded that the polymorphism of KIR gene is associated with susceptibility of leukemia in Hans. There may be a negative correlation between pathogenesis of leukemia and KIR 3DL1, KIR 3DS1, KIR 2DL1, KIR 2DL5 genes.

Abstract
AIMS To investigate the strength of association between anaemia and overall survival, locoregional control, and late radiation complications in patients with locally advanced oesophageal carcinoma undergoing radiotherapy with or without chemotherapy and hyperthermia. MATERIALS AND METHODS Between March 1996 and December 2002, 303 patients with locally advanced squamous cell carcinoma of oesophagus enrolled in three consecutive prospective phase III trials conducted in our department were included in this study. These patients received one of the following four irradiation schedules: late course accelerated hyperfractionated (LCAF) radiotherapy alone, LCAF combined with concurrent chemotherapy, LCAF combined with hyperthermia, and continuous accelerated hyperfractionated (CAHF) radiotherapy according to each protocol. According to the haemoglobin levels measured before radiotherapy, patients were stratified to normal haemoglobin group (> or = 12.0 g/dl for men, or > or = 11.0 g/dl for women) or anaemic group (< 12.0 g/dl for men, or < 11.0 g/dl for women). Overall survival, locoregional control rate and late irradiation toxicity were estimated by Kaplan-Meier method. RESULTS Of 303 eligible patients, 243 patients (80.2%) had normal haemoglobin level and 60 patients (19.8%) were anaemic. The 5-year overall survival was 39% in patients with normal haemoglobin level, whereas, 22%, with anaemia patients (P = 0.001). The 5-year locoregional control rate at 5 years was 68% in patients with normal haemoglobin, versus 62%, with anaemia patients (P = 0.050). The 5-year rate of radiation toxicity of grade 3 or greater was 29% in patients with normal haemoglobin level, but it was 8%, with anaemic patients (P = 0.033). From multivariate analyses, T stage, location of tumour and haemoglobin level were found to be independent predictors for survival. T stage, gender and haemoglobin level were independent predictors for locoregional control. It was also detected that age and haemoglobin level played as independent predictors for development of radiation toxicity. CONCLUSIONS For patients with locally advanced oesophageal carcinoma undergone irradiation, anaemia associated a statistically significant reduction in survival and locoregional control rates, but also decreased radiation toxicity rates. Therefore, haemoglobin level should be considered as a stratification variable in prospective clinical trials.

Abstract
To investigate the effects of D-limonene (D-L) on the cell growth and apoptosis in HL-60, K562 cells and to elucidate its mechanism, the influence of D-L on proliferation of HL-60 and K562 cells was determined by propidium iodide assay, the expression levels of mutant p53, bcl-2, bax gene were detected by cell morphological analysis, flow cytometry and immunohistochemistry staining, the D-L-inducing HL-60 and K562 cell apoptosis in vitro was observed systematically. The results showed that D-L inhibited HL-60 and K562 cell growth in a dose- and time-dependent manner with the IC50 of 0.75 mmol/L similarly, D-L induced apoptosis of HL-60 and K562 cells, and expression of bcl-2 gene was down regulated by D-L in a concentration-dependent manner in HL-60 cells. The bcl-2, mutant type of p53 genes were down regulated while bax gene was up regulated by D-L in a concentration-dependent manner in K562 cells. It is concluded that D-L can inhibit proliferation and induce apoptosis of HL-60 and K562 cells. The bcl-2, mutant type of p53 and bax may be involved in the gene regulation of D-L-induced apoptosis.

Abstract
OBJECTIVE To observe the effect of the modified artificial esophagus on postoperative stenosis in dogs. METHODS The models of defected esophagus were established in dogs. The double-layered membrane tube (modifying type) was implanted in the test group (n = 10) and the esophageal stent was further inserted when the stenosis occurred. The single pattern tube (original type) was transplanted to the control group (n = 30). The dilation treatment was performed to relieve the postoperative stenosis; alternatively, the esophageal stent was implanted in the unsuccessful dogs. RESULTS The average artificial esophagus removal time was 19.10 days in the test group, which was significantly lower than 39.07 days in the control group (t = 15.6, P = 0.000). No obstruction after removal was observed in the experimental group. The incidence of postoperative stenosis had no significant difference between these two groups. CONCLUSION The double-layered membrane tube can make the tube removal safer by shortening the removal time.

Abstract
Xilingzhimu, the rhizomes of Anemarrhena asphodeloides Bunge (Liliaceae), has been prescribed as antipyretic, anti-inflammatory, diuretic and hypoglycemic agents in Chinese traditional medicine. In this paper, two xanthone glycosides I and II, were isolated from Xilingzhimu by conventional method. The structures of I and II were identified on the basis of chemical reactions and UV, IR, 1HNMR, 13CNMR and DEPT. Compound I was identified as mangiferin and II is a new compound, named neomangiferin. Its structure is 7-O-beta-D-glucopyranosyl-mangiferin.

Abstract
OBJECTIVE To seek for the effective therapeutical method in treating non-Hodgkin's lymphoma (NHL). METHODS One hundred and sixty seven patients with non-Hodgkin's lymphoma were randomly divided into two groups, the treatment group, which consisted of 112 cases using Chinese herbs combined with chemotherapy and 55 cases of control group were treated by chemotherapy only. RESULTS The effective rate (CR + PR) in the combined group was 91.96% and survival rates of 1-, 3- and 5-year were 85.7%, 54.5% and 29.5% respectively, and median survival time was 554 days. In control group the effective rate was 72.73% and 1-, 3- and 5-year survival rates were 76.4%, 38.2% and 18.2% respectively, and the median survival time was 465 days. The difference of effective rates or 3-year survival rates between two groups was significant (P < 0.05). In the combined group the activity of NK cell, OKT3, OKT4 and ratio of OKT4/OKT8 were obviously raised after treatment (P < 0.01). And the level of platelet adhesion rate and the blood viscosity markedly decreased (P < 0.01), but in the control group the values of these indexes did not distinctly change. CONCLUSION Chinese herbs could enhance the immunologic function and improve the viscosity of blood of the patients with NHL. The side effect in the combination therapy group was less and milder than that in the chemotherapy group. These showed that Chinese herbs combined with chemotherapy was a safe and effective method for treating NHL and deserve to be recommended.

Abstract
The conventional surgical management of congenital subluxated lenses is frequently associated with a high incidence of complications leading to poor visual prognosis. Lensectomy through the pars plana with modern techniques of microsurgery and automated suction-cutting devices was performed on 11 patients (18 eyes) whose pre-operative visual acuities with the best optical correction ranged from 0.05-0.3, which were improved postoperatively to 0.5-1.0 during a follow-up of 3 to 60 months with an average of 36 months. The complications were accidental small cuts at the pupillary borders of 3 eyes, indicating that pars plana lensectomy is a safe procedure for the treatment of congenital subluxated lenses.

Abstract
1. [2'-2H]Inosine was made from inosine by tetraisopropyldisiloxanyl protection of the 3'- and 5'-positions, oxidation with dimethyl sulphoxide and acetic anhydride, immediate NaB2H4 reduction of the oxo sugar product and inversion at C-2' of the resultant protected [2'-2H]arabino-inosine by trifluoromethanesulphonylation and reaction with caesium propionate, followed by deprotection. 2. The equilibrium-perturbation technique was used to measure beta 2H(V/K) for phosphorolysis of this compound by the purine nucleoside phosphorylase of Escherichia coli as a function of pH. 3. The pH variation indicates an intrinsic effect of 1.068 masked by isotopically silent steps near the pH optimum. 4. The similar pH variation of these beta-deuterium effects and the alpha-deuterium effects measured previously [Stein & Cordes (1981) J. Biol. Chem. 256, 767-772; Lehikoinen, Sinnott & Krenitsky (1989) Biochem. J. 257, 355-359] for this reaction provides the first experimental reassurance for the common assumption that pH changes merely mask and unmask the chemical steps in an enzyme-catalysed reaction, and do not detectably alter transition-state structure. 5. The dihedral angle between the C-H-2' bond and the electron-deficient p-orbital at the transition state is in the range 32-48 degrees, in accord with an essentially planar furanose ring.

Abstract
Marfan's syndrome (MS) is an inherited disease of connective tissue. The most characteristic ocular change is dislocation of lens, but myopia and retinal detachment also can occur. We examined 11 MS patients using electroretinography (ERG). 6 cases showed normal ERG. 5 cases had abnormal ERG. One had retinal detachment. 3 had myopia and 1 case suffered from secondary glaucoma. The defects of visual function were shown by electrophysiological test in those MS patients.

Abstract
Through routine ocular examination of 279 Deaf-mute students in Lie De School in Guangzhou in 1988 by visual chart, Yu Zi Ping Pseudoisochromatic plate, portable slit lamp and direct ophthalmoscope, 100 persons (35.8%) were found to have ocular defects in one or both eyes. The incidence of ocular defects was higher than that of the normal populations. Among the ocular abnormalities, fundus defects occupied 28.6%, error of refraction, 17.9%. 17.9% of the eyes had the vision lower than 1.0 and the error of refraction was the main cause. Cases of hereditary syndromes were found: Usher syndrome, 2 cases; Goldenhar syndromes, 2 cases (brother and sister); Waardenburg syndrome, 1 case; von Recklinghausen's syndrome, 1 case. In comparing with the other articles, the ocular defect, visual disturbance, error of refraction, way of examination as well as types and characteristics of some syndromes were briefly discussed. The importance of special examinations for diagnosis, early correction of refractive error, avoidance of consanguineal marriage among deaf-mutes were emphasized.

Abstract
This article introduces the application of compound crystal trichosanthin to 179 difficult cases of artificial abortion including cases with extreme anteversion and anteflexion of uterus with a fine and long cervix, cases with uterine deformations, cases within 1 year after cesarotomy, and cases of recently induced abortion. Past experiences have indicated that there have been considerable difficulties in inducing abortion in such cases as the above, and that accidents have been liable to occur. The authors have recently employed compound crystal trichosanthin, composed of crystal trichosanthin, testosterone propionate and reserpine, and succeeded in bringing about drug expansion of uterus and abortion, and safe abortion at that. The success roles were as follows: 97.96% for the group with extreme anteversion and anteflexion of uterus with a fine and long cervix, 100% for the one with uterine deformations, 95.08% for the one with past cesarotomy and 96.72% for the one with recently induced abortion.
