BACKGROUND:Lumbar decompression and fusion is the most effective surgical method to treat lumbar degenerative spondylolisthesis.In recent years,the sagittal balance of the spine has been widely considered the key factor to adjust the outcome of spinal surgery,and factors that can affect the sagittal balance of the spine indirectly affect the surgical effect and prognosis. OBJECTIVE:To summarize the risk factors that can affect the sagittal balance of the spine during decompression and fusion due to lumbar spondylolisthesis,and play a certain reference role in the surgical treatment of lumbar spondylolisthesis. METHODS:With"lumbar spondylolisthesis,the sagittal plane balance of the spine,surgical treatment,risk factors"as the Chinese search terms,and"lumbar spondylolisthesis,sagittal balance,risk factor"as the English search terms,PubMed,Springer,ScienceDirect,Wanfang,VIP and CNKI were searched respectively.The focus of the search was from January 2010 to January 2023,and a few classic long-term articles were included.Preliminary screening was conducted by reading the title and abstract.After excluding repetitive research in Chinese and English literature,low-quality journals and irrelevant literature,67 articles were finally included for review. RESULTS AND CONCLUSION:(1)Degenerative lumbar spondylolisthesis is an important factor causing spinal canal stenosis and lumbar instability,and is the main cause of low back pain and intermittent claudication.Lumbar decompression,fusion and internal fixation is an effective way to treat degenerative lumbar spondylolisthesis.(2)In the past,the treatment of degenerative lumbar spondylolisthesis with decompression,fusion and fixation focused on thorough exploration and release of nerve roots,reduction of spondylolisthesis and solid internal fixation,but less attention was paid to the balance of sagittal plane of the spine.(3)With the popularization of lumbar decompression,fusion and internal fixation,complications caused by the sagittal imbalance of the spine gradually increased,resulting in poor prognosis of patients and even increased risk of secondary surgery.(4)Previous studies have only discussed the correlation between lumbar sagittal plane parameters and spinal sagittal plane balance,but have not in-depth studied the relevant factors causing spinal sagittal plane imbalance.(5)Our results show that open lumbar fixation and fusion,complete reduction of spondylolisthesis,selection of thicker pedicle screws,selection of larger fusion cages,and autologous bone transplantation are beneficial factors for maintaining sagittal balance.The higher the number of fusion segments,the higher the level of fusion segments is,which is a risk factor for sagittal plane imbalance.

Objective:To compare the efficacy of reduction and in situ intervertebral fusion fixation in the treatment of degenerative lumbar spondylolisthesis.Methods:A total of 182 patients (92 males and 90 females) with L 4 degenerative lumbar spondylolisthesis of Meyerding's classification of grade I and grade II, aged (62.6±6.8) years (range, 57-73 years), who underwent posterior L 4, 5 internal fixation and interbody fusion in the Department of Spinal Surgery, the Second Hospital of Shanxi Medical University, were retrospectively analyzed from January 2019 to December 2022. There were 105 cases of I-degree spondylolisthesis and 77 cases of II-degree spondylolisthesis. According to the operation method, the patients were divided into reduction intervertebral fusion fixation (reduction group) and in situ intervertebral fusion fixation group (in situ group). Imaging parameters such as lumber lordosis (LL), pelvic incidence (PI)-LL, L 3, 4 intervertebral space heights, fusion segment angle, and sagittal vertical axis (SVA) were measured on the pre- and post-surgical lumbar spine lateral radiographs. The visual analogue scale (VAS) and Oswestry Disability Index (ODI) of low back pain were recorded before and after surgery. The differences in clinical and imaging parameters were compared between reduction and in situ fusion group. Results:All 182 patients successfully completed the surgery and were followed up for 12.0±2.4 months (range, 9-15 months). The LL of the reduction group before surgery, immediately after surgery, and at the last follow-up were 46.9°±7.1°, 57.2°±5.9°, 55.6°±5.5°, respectively, with statistically significant differences ( F=87.61, P<0.001), with immediate and final follow-up being smaller than those in the in situ fixation group. The LL of the in situ fixation group before surgery, immediately after surgery, and at the last follow-up were 47.8°±7.2°, 50.5°±7.0°, and 48.7°± 6.4°, respectively, with no statistically significant difference ( F=2.83, P=0.062). The immediate and final follow-up of LL in the reduction group was lower than those in the in situ fixation group ( P<0.05). The fusion segment angles of the reduction group before surgery, immediately after surgery, and at the last follow-up were 14.2°±5.1°, 23.2°±4.7°, 23.2°±4.7°, respectively, with statistically significant differences ( F=152.87, P<0.001), with immediate and final follow-up after surgery being greater than before surgery. The fusion segment angles of the in situ fixation group before surgery, immediately after surgery, and at the last follow-up were 15.4°±5.9°, 18.2°±5.5°, and 17.4°±5.1°, respectively, with statistically significant differences ( F=4.69, P=0.009), with immediate and final follow-up being greater than before surgery. The fusion segment angulation in the reduction group was greater than that in the in situ fixation group at both the immediate and final follow-up ( P<0.05). The SVA of the reduction group before surgery, immediately after surgery, and at the last follow-up were 16.9±18.2 mm, 9.5±12.0 mm, and 8.7±11.3 mm, respectively, with statistically significant differences ( F=11.32, P<0.001), with immediate and final follow-up being smaller than before surgery. The SVA of immediately after surgery and at the last follow-up were both smaller than before surgery. The SVA of the in situ fixation group before surgery, immediately after surgery, and at the last follow-up were 16.4±17.2 mm, 14.3±15.5 mm, and 13.8±15.0 mm, respectively, with no statistically significant difference ( F=0.57, P=0.576). The SVA of the reduction group at immediate and final follow-up was lower than that of the in situ fixation group ( P<0.05). Conclusion:Both reduction and in situ intervertebral fusion fixation can effectively relieve the clinical symptoms of patients. Fusion fixation after reduction can improve the angulation of fusion segments to form segmental kyphosis, which is more conducive to improving SVA.

Objective To investigate the relationship between Toxoplasma gondii (T.gondii) infection and metabolic syndrome (MS).Methods A total of 20 577 patients who received serum test of anti-T.gondii IgG antibody in the National Health and Nutrition Examination Survey ( NHANES) of the United States from 2009 to 2014 were collected to analyze the clinical features of anti-T.gondii IgG antibody positive patients , and to compare metabolic related indicators in the antibody IgG positive and negative groups .The independent sample t-test, chi-square test, and logistic regression analysis were used to explore the risk factors of MS . Results A total of 2 746 participants were positive for the T.gondii antibody (13.34%), with a higher prevalence of male (14.44%vs 12.27%, χ2 ＝15.99, P＜0.01).Meanwhile, the prevalence of T.gondii increased with age and body mass index (BMI) (χ2 ＝979.98 and 50.85,respectively, both P＜0.01).Among the 2 191 patients with MS, 449 (20.49%) patients were positive for T.gondii.While 2 297 (12.49%) patients were anti-T.gondii positive in 18 386 non-MS patients.The difference was statistically significant (χ2 ＝78.504, P＜0.01).Age (t＝-37.37), BMI (t＝-4.28), glycosylated hemoglobin (t＝-11.81), fasting blood glucose (t＝-9.38), triacylglycerol (t＝-6.32), cholesterol (t＝-7.16), serum uric acid (t＝-5.25) and serum creatinine (t＝-7.69) in the seropositive group were all higher than those in the seronegative group (all P＜0.01).After adjusting for age and gender , the prevalence of T.gondii was an independent risk factor for MS (odds ratio [OR]＝1.147,P＝0.023).Conclusions BMI, blood lipids, blood uric acid and blood glucose are significantly increased in patients with T.gondii infection.T.gondii infection is an independent risk factor for MS.

Objective: To investigate the correlation between interleukin-6 (IL-6) single nucleotide polymorphism (SNP) and the occurrence and prognosis of hepatitis B virus-associated acute-on-chronic liver failure (HBV-ACLF). Methods: Patients with chronic hepatic diseases diagnosed as HBV infection in the Hepatology Center of the First Affiliated Hospital of Fujian Medical University from July 2012 to March 2018 were divided into HBV-ACLF and non-ACLF group. SNP genotyping of eight loci in IL-6 gene (rs1524107, rs1800795, rs1800797, rs2069827, rs2069830, rs2069837, rs2069840 and rs2069845) was determined by the improved multi-temperature ligase detection reaction (imLDRTM) technique. Simultaneously, case data were reviewed with the 3-months followed up survival condition of the ACLF group. Normally distributed data were expressed as arithmetic means and SDs, and t-test was adopted. Data with skewed distribution were expressed as medians with interquartile range, and were measured by non-parametric test. Multivariate logistic regression analysis was used to analyze the relative risk of genetic polymorphism and HBV-ACLF as well as the relationship between IL-6 SNPs with the occurrence and prognosis of HBV-ACLF. Results: Four hundred patients were included in the study, with 122 (30.5%) in the HBV-ACLF and 278 (69.5%) in the non-ACLF group. There were significant differences in total bilirubin, albumin, and white blood cell count, percentage of neutrophils, platelet count, alanine aminotransferase, aspartate aminotransferase, prothrombin time and international standardized ratio, creatinine and the model for end-stage liver disease score between the two groups (P < 0.001). The genotype of IL-6 genes (rs1800795, rs1800797, rs2069827, and rs2069830) of all subjects showed no mutation or the mutation rate under 1%. There was no significant difference in the genotype of IL-6 (rs1524107, rs2069837, rs2069840 and rs2069845) between the two groups (P > 0.05). Multivariate logistic regression analysis showed that the SNPs in the above four loci of IL-6 gene was not associated with HBV-ACLF risk, nor had significant correlation with the 3-months prognosis. Conclusion The SNP genotyping of eight loci in IL-6 gene (rs1524107, rs1800795, rs1800797, rs2069827, rs2069830, rs2069837, rs2069840 and rs2069845) is unrelated to the occurrence and short-term prognosis of HBV-ACLF.

Objective To investigate the relationship between hepatic steatosis and virological markers in patients with chronic hepatitis B (CHB ) during immune clearance (IC ) phase.Methods Pathology proven CHB patients in IC phase were collected from the Liver Center of the First Affiliated Hospital of Fujian Medical University from January 2009 to October 2016 .Patients were divided into non-to mild fatty liver (F0 －F1) group and moderate to severe fatty liver (F2 －F4) group according to the liver steatosis degree .The relationship between liver steatosis and virological markers in serum was compared .The measurement data were analyzed using independent sample t test ,and the count data were analyzed by chi-square test .Results A total of 298 patients were included ,including 237 males (79 .5%) and 61(20 .5%) females ,and the average age was (32 .4 ± 10 .3) years old .The 23 .5%(70／298) of these patients had liver steatosis .A total of 273 (91 .6%) cases were in F0－F1 group ,and the remaining 25 (8 .4%) cases were in F2 －F4 group.The patients in F2 － F4 group had higher body mass index ([25.90 ± 2.70] vs [21 .68 ± 2.90] kg／m2) ,serum triglyceride ([1.52 ± 0.77] vs [1.11 ± 0.55] mmol／L) and cholesterol ([4 .88 ± 1 .15] vs [4 .33 ± 0 .92] mmol／L) than F0－F1 group ,and the differences were all statistically significant (t＝ －7 .007 ,－2 .667 ,and －2 .751 ,respectively ,all P＜0 .05).In addition , the serum levels of HBsAg and HBV DNA in F2 －F4 group were also significantly higher than F0 －F1 group (t＝ －3 .291 and －2 .831 ,respectivelt ,both P＜0 .01).According to the grading of inflammation and fibrosis ,the differences of HBsAg and HBV DNA levels between F0 －F1 group and F2 －F4 group were statistically significant only in patients with more severe inflammation (t＝ －2 .738 and －2 .135 , respectively ,both P＜0 .05) or less severe fibrosis (t＝ －2 .258 and －2 .333 ,respectively ,both P＜0 .05).Conclusion Among CHB patients experiencing immune clearance ,serum HBsAg and HBV DNA levels are positively correlated with the severity of hepatic steatosis ,and this phenomenon is closely related to the degree of liver inflammation.

Objective To investigate the association between interleukin-22 (IL-22) single nucleotide polymorphisms (SNPs) and the prognosis of hepatitis B virus related acute-on-chronic liver failure (HBV-ACLF).Methods The patients with HBV-ACLF from the First Affiliated Hospital of Fujian Medical University were retrospectively studied.Seven SNP genotypes of IL-22 gene,including rs2227478,rs2227491,rs1179251,rs1179249,rs2227473,rs2227484,and rs11611206,were detected using imLDRTM multiple SNP typing kit and the distribution features of SNP genotypes were described.The relationship between the distribution of SNP genotypes and alleles and the prognosis of ACLF was analyzed.Comparison of genotypes and allele frequencies between groups were performed by chi-square test of R × C table or Fisher's exact tests.Binary logistic regression analysis was used to analyze whether IL-22 gene polymorphisms was an independent prognostic factor for patients with ACLF.Results A total of 122 patients with HBV-ACLF were included in this study.Ninety-two (75.1％) were male and 30 (24.59 ％) were female.Patients were stratified as survival group (90 cases) and non-survival group (32cases) according to the Results of three months follow-up.The genotype distribution of rs2227484 of IL-22 gene was significantly different between the two groups (x2=6.128,P=0.033).The A allele frequency in the non-survival group (15.6％) was significantly higher than that in the survival group (5.6％) with statistically significance (OR=0.318,95％ CI=0.126-0.804,P=0.012).There was no significant difference in the other six SNP genotypes of IL-22 gene between the two groups (all P＞0.05).However,binary logistic regression showed that rs2227484 of IL-22 gene was not an independent risk factor for the short-term mortality in HBV-ACLF patients (adjusted OR=3.102,95％ CI:0.939-10.250,P=0.063).Conclusions The A allele and AA genotype of rs2227484 of IL-22 gene may be associated with a short-term prognosis in patients with HBV-ACLF.

Objective: To observe the effects of follistatin (FST)on the skeletal muscle wasting of cancer cachexia mice and the expressions of Mstn, LncRNA-MALAT1 and Caspase-3, and to elucidate its associated molecular mechanisms.Methods:Thirty-two BALB/c mices were randomly assigned into:healthy control (HC) group,FST prevention (FP)group,FST treatment (FT)group and cancer cachexia (CC)group.The murine colon adenocarcinoma CT26 cells were inoculated subcutaneously into the mices in FP, FT and CC groups to establish the cancer cachexia models. The body weight, spontaneous activity and tumor growth were daily monitored.The mice in FP and FT groups were administrated with FST intraperitoneally on day 6 and 12 after inoculation.The samples were collected on day 20.The tumor and gastrocnemius weights of the mice were detected. The biochemical metabolism indexes and myofiber cross-sectional area of gastrocnemius tissue were detected.The mRNA expression levels of Mstn,Caspase-3 and LncRNA-MALAT1 were examined by Real-time PCR.The protein expression levels of Mstn and Caspase-3 were measured by Western blotting method. Results:Compared with CC group,the body weights,spontaneous activities,gastrocnemius weights and myofiber cross-sectional areas were increased (P <0.05);the serum levels of glucose,total protein and albumin of the mice in FP and FT groups were increased (P <0.05).The protein and mRNA expression levels of Mstn and Caspase-3 in gastrocnemius of the mice in CC group were significantly higher and the expression level of LncRNA-MALAT1 was significantly lower than those in HC group (P < 0.05).The mRNA and protein expression levels of Mstn and Caspase-3 in FP and FT groups were reduced and the expression level of LncRNA-MALAT1 was increased compared with CC group (P < 0.05).The prevention effect in FP group is better than FT group (P < 0.05). Conclusion:FST may alleviate the muscle wasting of the mice with cancer cachexia by inhibiting the expression of Mstn,thus upregulating the expression of LncRNA-MALAT1 which in turn to suppress the expression of Caspase-3.
