Comparative effectiveness and safety of 36 therapies or interventions for pregnancy outcomes with recurrent implantation failure: a systematic review and network meta-analysis.

PURPOSE: To investigate the effectiveness and safety of 36 different therapies for recurrent implantation failure (RIF) patients. METHODS: We searched PubMed, Embase, the Cochrane Library (CENTRAL), Web of Science, and China National Knowledge Internet (CNKI) from inception to August 24, 2022, with language in both English and Chinese. Randomized controlled trials (RCTs) and observational studies that provided data with one of pregnancy outcomes on RIF patients were included in the network meta-analysis (NMA). The odds ratios (OR) and 95% credible interval (CrI) on pregnancy outcomes were summarized by NMA with a random-effects model. We also analyzed data from only RCTs and compared whether the optimal treatment is the same for different failed embryo transfer attempts. RESULTS: The total of 29,906 RIF patients from 154 clinical studies (74 RCTs and 80 non-RCTs) were included in the NMA. In terms of implantation rate (IR), growth hormone (GH) (OR: 3.32, 95% CrI: 1.95-5.67) is the best treatment in all included studies; IVIG+PBMC (5.84, 2.44-14.1) is the best for clinical pregnancy rate (CPR); hyaluronic acid (HA) (12.9, 2.37-112.0) for live birth rate (LBR); and aspirin combined with glucocorticoids (0.208, 0.0494-0.777) for miscarriage rate (MR). The two-dimensional graphs showed that GH could maximize IR and CPR simultaneously; HA and GH could simultaneously increase IR and LBR to a large extent; HA could maximize IR and minimize MR. CONCLUSION: IVIG+PBMC, GH, and embryo medium enriched with HA could significantly improve pregnancy outcomes in patients with RIF. It appears that combination therapy is a potential administration strategy. TRIAL REGISTRATION: This study has been registered on PROSPERO (CRD42022353423).

Examining the gastric cancer survival gap between Asians and whites in the United States.

BACKGROUND: Globally, Asian countries bear a disproportionate gastric cancer burden. Asian Americans, the fastest growing minority population in the US, have higher gastric cancer survival than non-Hispanic whites (NHWs) despite higher incidence. Benefitting from uniform cancer registry standards within the US, we examine for the first time the heterogeneity in the Asian American population, which may elucidate the causes of these disparities. METHODS: SEER gastric cancer data from 2000 to 2012 were used to calculate 5-year survival estimates for NHWs and the six largest Asian ethnicities. Multivariate analyses were performed to identify critical prognostic factors and survival disparities between Asian groups and NHWs. RESULTS: We analyzed 33,313 NHW and 8473 Asian gastric cancer cases. All Asian groups had significantly higher 5-year survival than NHWs, at 29.8%. Among Asians, Koreans and Vietnamese had the highest and lowest survival, at 45.4% and 35.7%, respectively. The Korean survival advantage was largely attributable to relatively high proportions of localized stage and low proportions of cardia tumors. After adjusting for major prognostic factors, the survival disadvantage of NHWs, while attenuated, remained significant in comparison to all Asian groups (HR: 1.33, 95% CI: 1.24-1.43; reference: Korean). The survival disparities within the Asian groups vanished with adjustment. CONCLUSIONS: This study characterizes distinctive gastric cancer survival patterns among the six major Asian groups and NHWs in the US. The favorable survival for Koreans is largely attributable to specific clinical factors, particularly stage at diagnosis. The causes of the survival disadvantage for NHWs remain elusive.

Cancer incidence among Asian American populations in the United States, 2009-2011.

Cancer incidence disparities exist among specific Asian American populations. However, the existing reports exclude data from large metropoles like Chicago, Houston and New York. Moreover, incidence rates by subgroup have been underestimated due to the exclusion of Asians with unknown subgroup. Cancer incidence data for 2009 to 2011 for eight states accounting for 68% of the Asian American population were analyzed. Race for cases with unknown subgroup was imputed using stratified proportion models by sex, age, cancer site and geographic regions. Age-standardized incidence rates were calculated for 17 cancer sites for the six largest Asian subgroups. Our analysis comprised 90,709 Asian and 1,327,727 non-Hispanic white cancer cases. Asian Americans had significantly lower overall cancer incidence rates than non-Hispanic whites (336.5 per 100,000 and 541.9 for men, 299.6 and 449.3 for women, respectively). Among specific Asian subgroups, Filipino men (377.4) and Japanese women (342.7) had the highest overall incidence rates while South Asian men (297.7) and Korean women (275.9) had the lowest. In comparison to non-Hispanic whites and other Asian subgroups, significantly higher risks were observed for colorectal cancer among Japanese, stomach cancer among Koreans, nasopharyngeal cancer among Chinese, thyroid cancer among Filipinos, and liver cancer among Vietnamese. South Asians had remarkably low lung cancer risk. Overall, Asian Americans have a lower cancer risk than non-Hispanic whites, except for nasopharyngeal, liver and stomach cancers. The unique portrayal of cancer incidence patterns among specific Asian subgroups in this study provides a new baseline for future cancer surveillance research and health policy.

Building keypoint mappings on multispectral images by a cascade of classifiers with a resurrection mechanism.

Inspired by the boosting technique for detecting objects, this paper proposes a cascade structure with a resurrection mechanism to establish keypoint mappings on multispectral images. The cascade structure is composed of four steps by utilizing best bin first (BBF), color and intensity distribution of segment (CIDS), global information and the RANSAC process to remove outlier keypoint matchings. Initial keypoint mappings are built with the descriptors associated with keypoints; then, at each step, only a small number of keypoint mappings of a high confidence are classified to be incorrect. The unclassified keypoint mappings will be passed on to subsequent steps for determining whether they are correct. Due to the drawback of a classification rule, some correct keypoint mappings may be misclassified as incorrect at a step. Observing this, we design a resurrection mechanism, so that they will be reconsidered and evaluated by the rules utilized in subsequent steps. Experimental results show that the proposed cascade structure combined with the resurrection mechanism can effectively build more reliable keypoint mappings on multispectral images than existing methods.

Cellular mechanisms of monozygotic twinning: clues from assisted reproduction.

BACKGROUND: Monozygotic (MZ) twins are believed to arise from the fission of a single fertilized embryo at different stages. Monochorionic MZ twins, who share one chorion, originate from the splitting of the inner cell mass (ICM) within a single blastocyst. In the classic model for dichorionic MZ twins, the embryo splits before compaction, developing into two blastocysts. However, there are a growing number of ART cases where a single blastocyst transfer results in dichorionic MZ twins, indicating that embryo splitting may occur even after blastocyst formation. OBJECTIVE AND RATIONALE: For monochorionic MZ twins, we conducted a comprehensive analysis of the cellular mechanisms involved in ICM splitting, drawing from both ART cases and animal experiments. In addition, we critically re-examine the classic early splitting model for dichorionic MZ twins. We explore cellular mechanisms leading to two separated blastocysts in ART, potentially causing dichorionic MZ twins. SEARCH METHODS: Relevant studies including research articles, reviews, and conference papers were searched in the PubMed database. Cases of MZ twins from IVF clinics were found by using combinations of terms including 'monozygotic twins' with 'IVF case report', 'ART', 'single embryo transfer', or 'dichorionic'. The papers retrieved were categorized based on the implicated mechanisms or as those with unexplained mechanisms. Animal experiments relating to MZ twins were found using 'mouse embryo monozygotic twins', 'mouse 8-shaped hatching', 'zebrafish janus mutant', and 'nine-banded armadillo embryo', along with literature collected through day-to-day reading. The search was limited to articles in English, with no restrictions on publication date or species. OUTCOMES: For monochorionic MZ twins, ART cases and mouse experiments demonstrate evidence that a looser ICM in blastocysts has an increased chance of ICM separation. Physical forces facilitated by blastocoel formation or 8-shaped hatching are exerted on the ICM, resulting in monochorionic MZ twins. For dichorionic MZ twins, the classic model resembles artificial cloning of mouse embryos in vitro, requiring strictly controlled splitting forces, re-joining prevention, and proper aggregation, which allows the formation of two separate human blastocysts under physiological circumstances. In contrast, ART procedures involving the transfer of a single blastocysts after atypical hatching or vitrified-warmed cycles might lead to blastocyst separation. Differences in morphology, molecular mechanisms, and timing across various animal model systems for MZ twinning can impede this research field. As discussed in future directions, recent developments of innovative in vitro models of human embryos may offer promising avenues for providing fundamental novel insights into the cellular mechanisms of MZ twinning during human embryogenesis. WIDER IMPLICATIONS: Twin pregnancies pose high risks to both the fetuses and the mother. While single embryo transfer is commonly employed to prevent dizygotic twin pregnancies in ART, it cannot prevent the occurrence of MZ twins. Drawing from our understanding of the cellular mechanisms underlying monochorionic and dichorionic MZ twinning, along with insights into the genetic mechanisms, could enable improved prediction, prevention, and even intervention strategies during ART procedures.

Common mental disorders and risk of spontaneous abortion or recurrent spontaneous abortion: A two-sample Mendelian randomization study.

BACKGROUND: The direct causal relationships between common mental disorders (anxiety disorders, broad depression, major depressive disorder (MDD), bipolar disorder, and insomnia) and miscarriage or recurrent spontaneous abortion (RSA) are unclear. Therefore, this study aimed to explore these, using Mendelian randomization. METHODS: Genome-wide association studies (GWAS) meta-analyses with the largest sample size possible and selected independent single individuals of European ancestry were selected. Inverse variance weighted (IVW) was the main analysis method. The heterogeneity of the instrumental variables (IVs) was assessed using IVW and MR-Egger, and the horizontal pleiotropy of the IVs was assessed using MR-Egger and MR-PRESSO. RESULTS: Based on IVW results, the four mental disorders were found to be causally associated with spontaneous abortion (anxiety disorder: OR (95%CI), 1.230 (1.063-1.420), P = 0.0050; major depressive disorder: 1.690 (1.239-2.307), P = 0.0009; bipolar disorder: 1.110 (1.052-1.170), P = 0.0001; insomnia: 1.292 (1.076-1.552), P = 0.0060). Furthermore, no causal relationship was observed between broad depression and spontaneous abortion. Five common mental disorders were not causally associated with the RSA. LIMITATIONS: (1) Our analysis was limited to the European population; (2) the duration of mental disorders was not analyzed, as no information was available; and (3) it was difficult to completely detect genetic pleiotropy. CONCLUSIONS: Anxiety disorders, MDD, bipolar disorder, and insomnia may contribute to spontaneous abortion. Therefore, we should focus on the mental and sleep health of pregnant women. Future studies may be required on whether mental disorders directly lead to RSA, especially unexplained RSA.

The second polar body contributes to the fate asymmetry in the mouse embryo.

The polar bodies (PBs) are extruded microcells during oocyte meiosis and generally regarded as inessentials for embryonic development. Therefore, PBs have been widely used as important materials for pre-implantation genetic diagnosis in human. Here we report that the second PB (PB2) in the mouse zygote may play roles in cell-fate specification and post-implantation development. A subset of mRNAs encoding pluripotency-related factors are enriched in PB2. Nascent proteins may be synthesized in PB2 after fertilization and transport from PB2 to the zygote before the two-cell stage. The PB2-attached blastomere (pbB) at the two-cell stage, compared to the other blastomere (npbB), likely contributes more descendants to the inner cell mass (ICM) lineage in the blastocyst. Removal of PB2 from the zygote or transient blockage of material exchange between PB2 and the zygote by nocodazole treatment appears to cause a loss of the ICM fate bias of pbB. PB2 removal or nocodazole treatment also results in abnormal post-implantation development. Injection of PB2 lysate into pbB of PB2-removed two-cell-stage embryos may reset the cell-fate preference and rescue post-implantation development. Our data collectively suggest that PB2 would demarcate the earliest cell-fate asymmetry of the mouse zygote and be required for post-implantation development.

5' Half of specific tRNAs feeds back to promote corresponding tRNA gene transcription in vertebrate embryos.

5'tRFls are small transfer RNA (tRNA) fragments derived from 5' half of mature tRNAs. However, it is unknown whether 5'tRFls could feed back to regulate tRNA biogenesis. Here, we show that 5'tRFlGly/GCC and 5'tRFlGlu/CTC function to promote transcription of corresponding tRNA genes and are essential for vertebrate early embryogenesis. During zebrafish embryogenesis, dynamics of 5'tRFlGly/GCC and 5'tRFlGlu/CTC levels correlates with that of tRNAGly/GCC and tRNAGlu/CTC levels. Morpholino-mediated knockdown of 5'tRFlGly/GCC or 5'tRFlGlu/CTC down-regulates tRNAGly/GCC or tRNAGlu/CTC levels, respectively, and causes embryonic lethality that is efficiently rescued by coinjection of properly refolded corresponding tRNA. In zebrafish embryos, tRNA:DNA and 5'tRFl:DNA hybrids commonly exist on the template strand of tRNA genes. Mechanistically, unstable 5'tRFl:DNA hybrid may prevent the formation of transcriptionally inhibitory stable tRNA:DNA hybrids on the same tRNA loci so as to facilitate tRNA gene transcription. The uncovered mechanism may be implicated in other physiological and pathological processes.

prpf4 is essential for cell survival and posterior lateral line primordium migration in zebrafish.

Prpf4 (pre-mRNA processing factor 4), a key component of spliceosome, plays critical roles in pre-mRNA splicing and its mutations result in retinitis pigmentosa due to photoreceptor defects. In this study, we characterized a zebrafish prpf4t243 mutant harboring a Tol2 transposon-based gene trap cassette in the third intron of the prpf4 gene. Cells in the brain and spinal cord gradually undergo p53-dependent apoptosis after 28 hpf in prpf4t243 mutants, suggesting that a widespread function of prpf4 in neural cell survival. In addition, prpf4 is essential for survival of posterior lateral line primordial (pLLP) cells. prpf4 deficiency perturbs Fgf, Wnt/ß-catenin and chemokine signaling pathways and impairs pLLP migration. RNA-Seq analysis suggests that prpf4 deficiency may impair spliceosome assembly, leading to compensatory upregulation of core spliceosomal genes and alteration of pre-mRNA splicing. Taken together, our studies uncover an essential role of prpf4 in pre-mRNA splicing, cell survival and pLLP migration.

Molecular cloning and characterization of Crmdr1, a novel MDR-type ABC transporter gene from Catharanthus roseus.

A novel gene encoding a MDR-like ABC transporter protein was cloned from Catharanthus roseus, a medicinal plant with more than 120 kinds of secondary metabolites, through rapid amplification of cDNA ends (RACE). This gene (named as Crmdr1; GenBank accession no.: DQ660356) had a total length of 4395 bp with an open reading frame of 3801 bp, and encoded a predicted polypeptide of 1266 amino acids with a molecular weight of 137.1 kDa. The CrMDR1 protein shared 59.8, 62.5, 60.0 and 58.2% identity with other MDR proteins isolated from Arabidopsis thaliana (AAD31576), Coptis japonica (CjMDR), Gossypium hirsutum (GhMDR) and Triticum aestivum (TaMDR) at amino acid level, respectively. Southern blot analysis showed that Crmdr1 was a low-copy gene. Expression pattern analysis revealed that Crmdr1 constitutively expressed in the root, stem and leaf, but with lower expression in leaf. The domains analysis showed that CrMDR1 protein possessed two transmembrane domains (TMDs) and two nucleotide binding domains (NBDs) arranging in "TMD1-NBD1-TMD2-NBD2" direction, which is consistent with other MDR transporters. Within NBDs three characteristic motifs common to all ABC transporters, "Walker A", "Walker B" and C motif, were found. These results indicate that CrMDR1 is a MDR-like ABC transporter protein that may be involved in the transport and accumulation of secondary metabolites.

Cancer Mortality in Hispanic Ethnic Groups.

Background: Cancer is the leading cause of death among Hispanics. The burden of cancer mortality within Hispanic groups has not been well quantified.Methods: Cancer mortality rates for 2008-2012 in Florida were computed on the basis of race, ethnicity, and birthplace, specifically focusing on major Hispanic groups-Mexicans, Puerto Ricans, Cubans, Central Americans, South Americans, and Dominicans. Age-adjusted mortality rate ratios derived from negative binomial regression were used to compare Hispanics, aggregated and by group, to nonHispanic whites (NHW).Results: A total of 205,369 cancer deaths from 2008-2012 were analyzed, of which 22,042 occurred in Hispanics. Overall cancer mortality rates were lower for Hispanics, 159 and 100 per 100,000 in males and females, respectively, compared with 204 and 145 per 100,000 in NHWs, largely driven by relatively low rates of lung and breast cancers among Hispanics. However, Hispanics had a higher risk of death from stomach and liver cancers, both infection-related. Of all Hispanic groups, Mexicans had the lowest mortality, whereas Cubans had the highest, with significantly higher mortality for colorectal, endometrial, and prostate cancers.Conclusions: Compared with other Hispanic groups, Cubans and Puerto Ricans had significantly higher rates. For these longer-established populations in the United States, increases in diet and obesity-related cancers are evident. Some groups show excesses that clearly fall out of the common Hispanic patterns, with implications for public health: Cubans for colorectal cancer, Puerto Ricans for liver cancer, and Dominicans for prostate cancer.Impact: Cancer mortality outcomes in Hispanics vary between ethnic groups. Research and public health strategies should consider this heterogeneity. Cancer Epidemiol Biomarkers Prev; 26(3); 376-82. ©2017 AACR.

[Isolation and characterization of a 2C-methyl-D-erythritol 2,4-cyclodiphosphate synthase gene from Taxus media].

2C-methyl-D-erythritol 2,4-cyclodiphosphate (MEC) synthase (MECS, EC: 4.6.1.12) is the fifth enzyme of the nonmevalonate terpenoid pathway for isopentenyl diphosphate biosynthesis and further Taxol biosynthesis. The full-length MECS cDNA sequence (GenBank accession number DQ286391) was cloned and characterized for the first time from Taxus media, using Rapid Amplification of cDNA Ends (RACE) technique. The full-length cDNA of Tmmecs was 1081 bp containing a 741 bp open reading frame (ORF) encoding a peptide of 247 amino acids with a calculated molecular mass of 26.1 kDa and an isoelectric point of 8.97. Comparative and bioinformatic analyses revealed that TmMECS had extensive homology with MECSs from other plant species. Phylogenetic analysis indicated that TmMECS was more ancient than other plant MECSs. Southern blot analysis revealed that Tmmecs belonged to a small gene family. Tissue expression pattern analysis indicated that Tmmecs expressed constitutively in all tissues including roots, stems and leaves. The cloning and characterization of Tmmecs will be helpful to understand more about the role of MECS involved in the Taxol biosynthesis at the molecular level.

Embryonic hematopoiesis in vertebrate somites gives rise to definitive hematopoietic stem cells.

Hematopoietic stem cells (HSCs) replenish all types of blood cells. It is debating whether HSCs in adults solely originate from the aorta-gonad-mesonephros (AGM) region, more specifically, the dorsal aorta, during embryogenesis. Here, we report that somite hematopoiesis, a previously unwitnessed hematopoiesis, can generate definitive HSCs (dHSCs) in zebrafish. By transgenic lineage tracing, we found that a subset of cells within the forming somites emigrate ventromedially and mix with lateral plate mesoderm-derived primitive hematopoietic cells before the blood circulation starts. These somite-derived hematopoietic precursors and stem cells (sHPSCs) subsequently enter the circulation and colonize the kidney of larvae and adults. RNA-seq analysis reveals that sHPSCs express hematopoietic genes with sustained expression of many muscle/skeletal genes. Embryonic sHPSCs transplanted into wild-type embryos expand during growth and survive for life time with differentiation into various hematopoietic lineages, indicating self-renewal and multipotency features. Therefore, the embryonic origin of dHSCs in adults is not restricted to the AGM.

[RISK FACTORS FOR INCIDENTAL DUROTOMY DURING LUMBAR SURGERY].

OBJECTIVE: To evaluate the risk factors for incidental durotomy (ID) during lumbar surgery. METHODS: Eighty-six patients with ID and 86 patients with no ID (who were matched 1:1 in surgeons and surgery time) were selected from 2 235 patients who underwent lumbar surgery between January 2010 and December 2012. The gender, age, body mass index, history of smoking, alcoholism, nonsteroidal drug use, the etiology, lumbar surgery history, revision surgery, surgical approach, osteoporosis, diabetes, and surgical procedure were compared between 2 groups. Logistic regression analysis was applied to analyze the risk factors for ID. RESULTS: There was significant difference (P < 0.05) in etiology, surgical approach, revision surgery, lumbar surgery history, and surgical procedure between patients with ID and patients with no ID, which were then included in multivariate analysis. Logistic regression analysis demonstrated that lumbar surgery history, revision surgery, and minimal invasive surgery were risk factors for ID during lumbar surgery (P < 0.05). CONCLUSION: Lumbar surgery history, revision surgery, and minimal invasive surgery were risk factors for ID during lumbar surgery, thus surgery for patients with the above histories should be carefully performed to prevent ID.

Construction, expression and tumor targeting of a single-chain Fv against human colorectal carcinoma.

AIM: A single-chain antibody fragment, ND-1scFv, against human colorectal carcinoma was constructed and expressed in E.coli, and its biodistribution and pharmacokinetic properties were studied in mice bearing tumor. METHODS: V(H) and V(L) genes were amplified from hybridoma cell IC-2, secreting monoclonal antibody ND-1, by RT-PCR, and connected by linker (Gly(4)Ser) (3) to form scFv gene, which was cloned into expression vector pET 28a(+) and finally expressed in E.coli. The expressed product ND-1scFv was purified by metal affinity chromatography using Ni-NTA, its purity and biological activity were determined using SDS-PAGE and ELISA. ND-1scFv was labeled with (99m)Tc, and then injected into mice bearing colorectal carcinoma xenograft for phamacokinetic study in vivo. RESULTS: SDS-PAGE analysis showed that the relative molecular weight of recombinant protein was 30kDa with purity of 94 %. ELIAS assay revealed that ND-1scFv retained the immunoactivity of parent mAb, being capable of binding specifically to human colorectal carcinoma cell line expressing associated antigen. Radiolabeled ND-1scFv exhibited rapid tumor targeting, with specific distribution in mice bearing colorectal carcinoma xenograft observed as early as 1 h following injection. In vivo pharmacokinetic studies also demonstrated that ND-1scFv had very rapid plasma clearance (T(1/2)alpha of 5.7 min, T(1/2)beta of 2.6 h). CONCLUSION: ND-1scFv shows significant immunoactivity, and better pharmacokinetic and biodistribution characteristics compared with intact mAbs, demonstrating the possibility as a carrier for tumor-imaging.

Prevention of type 2 diabetes in urban American Indian/Alaskan Native communities: The Life in BALANCE pilot study.

OBJECTIVE: The Life in BALANCE (LIB) study is a pilot translational study modeling the Diabetes Prevention Program (DPP) intensive lifestyle coaching intervention among an underserved, high-risk population: American Indians/Alaska Natives (AI/ANs) living in a large urban setting (Las Vegas, Nevada). RESEARCH DESIGN AND METHODS: A total of 22 overweight/obese AI/ANs (age, 39.6 ± 10.4 years; BMI, 34.1 ± 6.3 kg/m2) at increased risk for developing type 2 diabetes (HbA1c > 5.4 (36 mmol/mol) < 6.4 percent (46 mmol/mol) participated in the program between April and December, 2011. Study participants completed a 16 week intensive lifestyle coaching intervention. In addition to obtaining qualitative data regarding opportunities and challenges of applying the lifestyle intervention for AI/AN participants in an urban setting, clinical data, including BMI, waist circumference, blood pressure, fasting blood glucose, and blood lipids (HDL, LDL and Triglycerides), were collected. RESULTS: Only 12 of the 22 participants remained in the LIB program at the final post-program follow-up. Participants demonstrated significant decreased waist circumference and elevated HDL cholesterol. Triglycerides manifested the highest percentage change without statistical significance. No significant change was observed in blood pressure or fasting blood glucose. CONCLUSIONS: LIB participants' improvements in BMI, waist circumference, HDL cholesterol and triglycerides suggests type 2 diabetes prevention programs aimed at urban AI/ANs show significant potential for reducing the risk of developing type 2 diabetes among this underserved and high risk community. Qualitative data suggest the main challenge for type 2 diabetes prevention specific to this population is a need for improved community outreach strategies.

[Clinical effects of the treatment of gastrointestinal dysfunction after stable thoracolumbar fractures with Simo decoction oral liquid].

OBJECTIVE: To evaluate the clinical effects of Simo Decoction Oral Liquid for the treatment of gastrointestinal dysfunction after stable thoracolumbar fractures. METHODS: From May 2005 to July 2008, 81 patients with stable thoracolumbar fractures were randomly divided into treatment group (41 cases) and control group (40 cases) according to a random digits table. The treatment group included 32 males and 9 females with an average age of (47.19 +/- 5.18) years old ranging from 21 to 55 years, and the course was from 1 to 45 hours with an average of (7.83 +/- 1.29) hours. The control group included 30 males and 10 females with an average age of (46.31 +/- 3.72) years ranging from 20 to 54 years,and the course was from 1.5 to 43 hours with an average of (8.15 +/- 1.63) hours. The treatment group were dealed with Simo Decoction Oral Liquid,and the control group with neostigmine for acupoint block in bilateral Foot-Three-Li. The recovery of gastrointestinal function and the first passage of gas by anus were compared. RESULTS: The time of recovery of gastrointestinal function in treatment group (7.27 +/- 3.14) h was shorter than that in control group (10.12 +/- 3.62) h. The time of first passage of gas by anus in treatment group (15.39 +/- 13.70) h was significantly shorter than that in contral group (24.02 +/- 18.11) h. The total effective rate in treatment group was higher than that in control group. CONCLUSION: Both the treatment group and the control group have clinical effects in treatment of the restoration of gastrointestinal dysfunction after the stable thoracolumbar fractures, but the treatment group has more remarkable therapeutic effect and less side effects.
