ABSTRACT

Objective: To summarize the clinical features and genetic characteristics of Zellweger spectrum disorder caused by PEX6 gene variation. Methods: This was a case series research. Clinical date and genetic results of 2 neonatal cases of Zellweger syndrome caused by PEX6 gene variation in Wuhan Children's Hospital, Tongji Medical College, Huazhong University of Science & Technology and Affiliated Hospital of Guangdong Medical University from July 2021 to July 2022 were retrospectively collected and analyzed. Literature up to August 2023 was searched from electronic databases of China National Knowledge Infrastructure (CNKI), Wanfang Data and PubMed with the combined keywords of "Zellweger syndrome" "Zellweger spectrum disorder", and "PEX6 gene" both in Chinese and English. The main clinical features and genetic characteristics of Zellweger spectrum disorder caused by PEX6 gene variation were summarized. Results: The 2 male neonates both developed clinical manifestations as dyspnea, hypotonia, feeding difficulties, enlarged fontanelle, and high palatine arch after birth. Biochemical parameters indicated elevated bile acids, and the cranial ultrasound showed the enlarged bilateral ventricles and subependymal cyst in both 2 neonates. Zellweger syndrome was confirmed by whole exome sequencing, and the results revealed PEX6 gene variation in the 2 neonates, including compound heterozygous variants c.315G>A and c.2095-3T>G, and homozygous variant c.506_507del. Case 1 was hospitalized for 5 days, and case 2 for 32 days; they both died shortly after being discharged (the specific time is unknown). Literature review found 26 patients, including 2 neonates in this study, with Zellweger spectrum disorder caused by PEX6 gene defect reported in 1 Chinese article and 11 English articles. Clinical features included hearing loss (19 cases), developmental delay (19 cases), vision impairment (19 cases), elevated very long chain fatty acids (17 cases), brain malformations (15 cases), hypotonia (12 cases), hepatic insufficiency (12 cases), distinctive facies (10 cases), and dental impairment (9 cases). Compound heterozygous variations dominated the variation types (15 cases), and the frameshift variations (16 cases) were the main pathogenic variations. Conclusions: Zellweger spectrum disorder should be considered when neonates show hypotonia, feeding difficulty, distinctive facial appearance, brain malformations and failure of hearing screening, or when older children show retinitis pigmentosa, sensorineural hearing loss, amelogenesis imperfecta and developmental delays. Detection of genetic variation in the PEX gene is crucial for definitive diagnosis.

ABSTRACT

OBJECTIVE To investigate the implementation effects of the national centralized drug volume-based procurement policy (abbreviated as “national centralized procurement policy”) in Guangxi Zhuang Autonomous Region prefecture, and to provide a reference for the future centralized drug procurement work of the medical institution. METHODS Drug procurement data before and after policy implementation were included in the study. The six secondary indicators (such as availability, affordability, and drug safety) and eighteen third-level indicators (such as completion rate of agreed purchase volume, affordability level, drug revenue proportion) were introduced, guided by the policy objectives and issues of concern to policy beneficiaries. Descriptive statistics was adopted to analyze the data before and after policy implementation (in 2019 and 2020) in terms of differences and change trends. RESULTS In terms of accessibility, the participation rate of medical institutions in Guangxi Zhuang Autonomous Region was 92.55%, the proportion of diseases involved and median completed procurement rate were 40.16%, and 287.82% respectively, and the total centralized delivery rate was 97.20%. In terms of affordability, the total reduction amplitude in drug price was 74.80% from 2019 to 2022; the charge for medicine per capita in hospitalization, the proportion of medicine used for outpatient service and hospitalization, decreased by 17.61%, 10.22%, and 20.10% in order; the burden levels on medical fares for patients were all below 1 in addition to chronic diseases, and anti-tumor drugs. In terms of the impact on medicine, the ratio of adverse drug reaction event cases in 2022 was 66.00%, an increase of 1.29% compared to the previous; since the implementation of the policy, 12 drugs from local pharmaceutical enterprises from Guangxi Zhuang Autonomous Region had passed the consistency evaluation, and the market concentration rate of the top 8 pharmaceutical companies was less than 20.00%. In terms of the impact on healthcare and medical insurance, the public medical institutions achieved generic substitution for originator drugs mostly until 2022; about 9.12% of drugs that were non- centrally purchased in the same category were used; 63.39% of people under investigation did not show a need for a second dressing change; drug expenditure decreased by 2.459 billion yuan. CONCLUSIONS The national centralized procurement policy achieves a significant effect in Guangxi Zhuang Autonomous Region. On the other hand, attention should be paid to these suggestions as follows: expanding the category of drugs used in clinic, conducting clinically comprehensive evaluation of selected drugs, and improving reasonable allocation strategy, etc.

ABSTRACT

Objective:To evaluate the clinical application of online adaptive radiotherapy based on iterative cone-beam computed tomography (iCBCT) for the pelvic malignancies.Methods:This was a prospective clinical trial of iCBCT guided online adaptive radiotherapy for pelvic malignancies in Department of Radiation Oncology, Peking Union Medical College Hospital. Clinical data of 13 patients with pelvic malignancies who received online adaptive radiotherapy from August to November, 2022 were preliminarily analyzed (2 cases of cervical cancer, 4 postoperative cervical cancer, 3 postoperative endometrial cancer, 3 bladder cancer and 1 prostate cancer). The feasibility of online adaptive radiotherapy, adaptive radiotherapy time, the frequency and magnitude of edits for organs at risk and target volume, target volume coverage and organs at risk doses were analyzed. Statistical analysis was performed by SPSS software. Data conforming to normal distribution were described by Mean±SD, and data with non-normal distribution were expressed by M ( Q1, Q3). Data with homogeneous variances were analyzed by t-test, and data with non-normal distribution or heterogeneous variances were analyzed by nonparametric test. Results:The average adaptive time was 15 min and 38 s (from acceptance of acquired CBCT scan to completion of the final plan selection). 85.4% (830/972 fractions) of influencer structures (system-defined organs adjacent to and with high impact on the generation of clinical target volume and planning target volume, primarily bladder, rectum and small intestine in pelvic neoplasms) automatically generated by artificial intelligence required no edits or minor editors, and 89.8% (491/547 fractions) of clinical target volume automatically generated by artificial intelligence required no edits or minor editors. The adapted plan was adopted in 98.5% (319/324 fractions) of radiotherapy fractions. Compared with the scheduled plan, the adapted plan showed better target volume coverage and reduced the dose of organs at risk.Conclusions:iCBCT guided online adaptive radiotherapy for the pelvic malignancies can be achieved within clinically acceptable timeslots. In addtion, better dose coverage of target volume shows the advantages of online adaptive radiotherapy.

ABSTRACT

@#AIM: To evaluate the efficacy of mycophenolate mofetil(MMF)on the prevention of relapse and visual prognosis of patients in neuromyelitis optica spectrum disorders(NMOSD)with AQP4 antibody positive optic neuritis. <p>METHODS: We retrospectively reviewed 11 patients with initial diagnosis of NMOSD and AQP4 antibody positive optic neuritis from January 2017 to December 2019. Among the 11 patients, 3 were male and 8 were female. The unique core clinical manifestation of NMOSD was optic neuritis. The onset age was 36.3±6.0(27-47)years old. Duration of the disease was 3.4±1.4(2.2-6.8)a. MMF was added in the relieving period of NMOSD for 1a or over 1a. Annualized relapsing rate(ARR), best corrected vision activity(BCVA)and adverse reactions of MMF were recorded.<p>RESULTS: The median time of MMF treatment was 18(12, 36)mo. The ARR was 0.66/a at baseline and 0.16/a after the treatment. There were 91% of the patients had decreased ARR and 82% of them had no clinical relapse. The patients had significant improvement on ARR after MMF treatment(<i>P</i><0.05 ). In total, there was no significant difference between the mean BCVA after treatment and that at baseline(<i>P</i>>0.05). Of the 11 patients, 3 patients had side effects(27%), including 1 patient with elevated liver transaminase(9%), and 2 patients with mild gastrointestinal reaction(18%)during follow-up period. None of them discontinued MMF due to adverse events.<p>CONCLUSION: MMF treatment for AQP4 antibody positive NMOSD can reduce the ARR of optic neuritis to a certain extent and protect the visual function of patients.

ABSTRACT

Objective To investigate the clinical effect of transcatheter arterial chemoembolization (TACE) combined with microwave ablation (MWA) (TACE-MWA) versus repeat resection (RR) in the treatment of recurrent hepatocellular carcinoma (RHCC). Methods A total of 178 patients with RHCC who were admitted to The Second People's Hospital of Neijiang from June 2015 to September 2020 were enrolled, and according to the treatment modality, they were divided into RR group with 64 patients and TACE-MWA group with 114 patients. Baseline demographic data, liver function, and tumor conditions before treatment were recorded, and the patients were followed up to October 2021 to compare postoperative overall survival (OS) time and recurrence-free survival (RFS) time between the two groups. Subgroup analysis based on recurrence pattern (recurrence time and tumor size) was performed, and the influencing factors for prognosis were analyzed. The independent samples t -test was used for comparison of continuous data between groups, and the chi-square test was used for comparison of categorical data; the Kaplan-Meier method was used for postoperative survival rate, the Log-rank test was used for survival difference analysis, and a multivariate Cox regression analysis was used to investigate independent risk factors for survival. Results The multivariate analysis showed that tumor diameter, alpha-fetoprotein (AFP) level, alanine aminotransferase, albumin, and time to recurrence were independent prognostic factors for OS (all P 2 years), there were significant differences between the two groups in median OS (54.0 months vs 36.0 months, χ 2 =6.171, P =0.013) and median RFS (28.0 months vs 21.0 months, χ 2 = 5.211, P =0.022). For RHCC with a tumor diameter of ≤5 cm, there was a significant difference in median OS between the two groups (33.0 months vs 27.0 months, χ 2 =6.447, P =0.011). Conclusion RR has a similar clinical effect to TACE-MWA in RHCC with early recurrence or a tumor diameter of > 5 cm, but RR should be the first choice for RHCC with late recurrence or a tumor diameter of ≤5 cm.

ABSTRACT

Objective To compare the corneal biomechanical parameters identified from uniaxial tensile test under fast and slow loading. Methods The stress-strain and stress relaxation data were obtained from uniaxial tensile tests on corneal strips from 15 healthy adult rabbits at average loading rate of 0.16 mm/s and 0.02 mm/s, respectively. A visco-hyperelastic model was applied to analyze the loading and unloading data from the fast tensile tests, where the model parameter set was denoted by Gvh. The first-order Ogden model and second-order Prony series model were used to fit stress-strain and stress relaxation data from the slow tensile tests, respectively, in which the model parameter set was denoted by Gvh. Correlation analysis was used to compare the correlation of parameters between Gvh and GOP. Results All the goodness-of-fits to the three data sets were greater than 0.95. There were significant differences in 5 (μ, A1, A2, τ1, τ2,) of the 6 parameters between Gvh and GOP (P<0.05), and the Ogden model parameters was positively correlated between the two groups. Conclusions There are differences in corneal biomechanical parameters identified by data from uniaxial tensile tests under fast and slow loading. The results provide a preliminary research basis for further exploring the use of clinical data to identify corneal biomechanical properties.

ABSTRACT

Objective@#To compare T-cell receptor (TCR) β chain complementarity-determining region 3 (CDR3) in the patients with coexistence of HBsAg and HBsAb and other HBV infected patients. @*Methods@#The clonotype and diversity of CDR3 in blood of group cases (positive HBsAg and HBsAb) (n=11), control 1 (negative HBsAg and positive HBsAb) (n=10) and control 2 (positive HBsAg and negative HBsAb) (n=10) were analyzed by high-throughput TCR sequencing with Illumina HiseqX10. @*Results@#In the case group, the overlap rate of 6.28% (0.25%, 13.10%) was detected between any two samples, which was significantly lower than the overlap rate of 10.49% (6.20%,17.30%) seen in control 1 group (P=0.008). In control 2 group, the overlap rate of 2.60% (0.13%,13.69%) was significantly lower than control 1 group (P=0.001). There was no difference between case group and control 2 group. After pairwise comparison between the three groups, the frequency of clonotype TRBV7-2/TRBD1/TRBJ2-1 in case group was higher than that of control 1 group (P=0.029), the frequency of TRBV7-3/TRBD1/TRBJ2-7 in case group was lower than that of control 1 group (P=0.031). The difference of TRBV5-8 was significant in comparing case group with control 1 group (P=0.047). There were 14 clonotypes which had differences between case group and control 2 group in frequency. TRBV28was significant in comparing case group with control 2 group (P=0.028). For diversity, there was no difference among the three groups. @*Conclusion@#Clonotype TRBV7-2/TRBD1/TRBJ2-1, TRBV7-3/TRBD1/TRBJ2-7 and TRBV5-8 were associated with coexistence of HBsAg and HBsAb, but the diversity was not associated with TCR β chain CDR3.

ABSTRACT

ObjectiveTo investigate the influence of dual positivity of HBsAg and anti-HBs on the development of hepatocellular carcinoma (HCC) in patients with hepatitis B virus (HBV) infection. MethodsPubMed, Embase, Cochrane Library, CNKI, and Wanfang Data were searched for articles on the influence of dual positivity of HBsAg and anti-HBs on the risk of HCC published from July 1, 1975 to March 27, 2019. RevMan5.3 and Stata11.2 were used for statistical analysis of data. A heterogeneity analysis was performed for the studies included; a random effects model was used in case of significant heterogeneity, and a fixed effects model was used in case of non-significant heterogeneity. Odds ratio (OR) and corresponding 95% confidence interval (CI) were used to investigate the association of dual positivity of HBsAg and anti-HBs with the development of HCC. Begg funnel plots were used to investigate publication bias. By removing one article each time, the sensitivity analysis was used to assess the quality and reliability of the Meta-analysis. ResultsA total of 4 articles were included, with 2 studies in the Korean population and 2 in the Chinese population, and there were 3042 patients in total. The meta-analysis showed that there was no significant association between dual positivity of HBsAg and anti-HBs and the development of HCC (OR=1.46, 95%CI: 0.76-2.80, P=0.25). A country-based subgroup analysis showed significant association between dual positivity of HBsAg and anti-HBs and the development of HCC in the Korean population (OR=2.67, 95%CI: 1.61-4.43, P=0.000 1), while no significant association was found in the Chinese population (OR=0.89, 95%CI: 0.48-1.64, P=0.70). ConclusionThere is no significant association between dual positivity of HBsAg and anti-HBs and the development of HCC, and further studies are needed in future.

ABSTRACT

Objective To investigate the technique and outcome of primary management of skull base fracture and cerebrospinal fluid (CSF) leakage by emergency surgery in patients with severe craniocerebral trauma. Methods A total of 16 patients with severe brain injury, skull base fracture and CSF leakage hospitalized in Department of Neurosurgery, Tianjin Medical University General Hospital from January 2014 to December 2015 were retrospectively analyzed. All of patients underwent emergency surgery to remove the hematoma and repair the skull base fracture, including anterior skull base repair in 12 patients and middle temporal skull base repair in 4 patients. During the surgery, the inner wall of the frontal sinus was managed by electrocautery, then removal of frontal sinus mucosa, hydrogen peroxide and iodophor rinse were used. The repairing and forming of the orbital roof were performed for the severe deformation cases. All bone fractures and fissures were filled with muscle blocks and biological glue and covered with a pedicled muscle flap. In addition, after close suturing of epidural, the intact periosteum under the skin flap was used to tile the skull base. No external material was used in the whole process. Results Among the 16 patients, 14 (87.5%) patients were successfully repaired by emergency surgery, and 2 cases (12.5%) failed. One of the patients who failed to repair the fracture was with the middle skull base fracture, severe fracture of skull base and mastoid, and extensive exposure of mastoid air chamber with large bone mass. This patient failed secondary surgical repair and died with severe infection. Another one case who failed primary surgery was with severe bone fractures in the anterior, middle and posterior skull base, which could not be completely repaired. This patient was also combined with infection and dead ultimately. Conclusion Primary repair in patient with severe head injury combined with skull base fracture, which needs surgical intervention can reduce further injury and save the patient's life. The key to the operation is to determine the operative principle and to repair the skull base tightly.

ABSTRACT

OBJECTIVE@#To investigate potential human leucocyte antigen (HLA)-A2-restricted epitope peptides of glypican-3 (GPC3) and determine the cytotoxicity of peptide-specific cytotoxic T lymphocytes (CTLs) against hepatocellular carcinoma (HCC) cells.@*METHODS@#The potential HLA-A*0201-restricted GPC3 peptides were screened using computer algorithms, T2 cell-binding affinity and stability of peptide/HLA-A*0201 complex assay. The peptide-specific CTLs were generated and their cytotoxicity against GPC3 SMMC 7721 and HepG2 cells was detected using IFN-γ based enzyme-linked immunospot and lactate dehydrogenase release assays in vitro.@*RESULTS@#A total of six peptides were identified for bindings to HAL-A2 and the GPC3 522-530 and GPC3 229-237 peptides with HLA-A*0201 molecules displayed high binding affinity and stability. The CTLs induced by the GPC3 522-530 or positive control GPC3 144-152 peptide responded to the peptide by producing IFN-γ, which were abrogated by treatment with anti-HLA-A2 antibody. The GPC3 522-530-specific CTLs responded to and killed SMMC 7721 and HepG2 cells, instead of GPC3-silenced SMMC 7721 or HepG2 cells. GPC3 522-530-specific CTLs response to HCC cells was blocked by anti-HLA-A2 antibody.@*CONCLUSIONS@#The GPC3 522-530 peptide contains antigen-determinant and its specific CTLs can effectively kill HCC in a HLA-A2-restricted and peptide-dependent manner. Our findings suggest that this peptide may be valuable for development of therapeutic vaccine.

Objective To establish standard parameters of cervical alignment and cervical range of motion(ROM) in asymptomatic population,and to explore the influential factors such as age,sex and cervical disc degeneration.Methods The cervical standard lateral,flexion and extension plain radiographs of 212 asymptomatic volunteers were analyzed retrospectively.The volunteers,including 128 females and 84 males with ages ranging from 20 to 79 years,were divided into 6 groups from 3rd to 8th decade of life and were divided into 4 groups based on the scoring system of cervical disc degeneration.These plain films were blindly measured by 3 spine surgeons with Mimics software,and each spine surgeon mcasured them for 3 times.Several parameters,including C2-C7 cervical alignment,total ROM,flexion ROM,extension ROM and segmental ROM were measured.The score of disc degeneration were assessed from C2-C3 to C6-C7.Pearson correlation analyses was used to quantify the relation between cervical alignment and total ROM.Multiple linear regression analyses were required to account for influential factors.Inter-and intrarater correlation coefficient was analyzed.Results The C2-C7 cervical alignment was 21.40°± 12.15°,and the total ROM was 63.59°± 15.37°.Sex had a significant impact on the cervical alignment (regression coefficient was-2.472,P < 0.05).Both sex and age had significant impacts on the total ROM (regression coefficient was 3.863 and-6.463 respectively,P < 0.05).Sex had a significant impact on C2,3 and C5,6 segmental ROM; age had a significant impact on all of the five segmental ROM from C2,3 to C6,7; cervical disc degeneration had a significant impact on the C4-5,C5-6 and C6-7 segmental ROM.The cervical alignment had no significant association with both of the extension and total ROM (r=-0.106 and 0.215,respectively,P > 0.05),but had a significantly negative association with flexion angle (r=-0.401,P< 0.05).The measurement of cervical alignment,total ROM and segmental ROM showed excellent intra-rater agreement and excellent inter-rater agreement.Conclusion Sex is an influential factor of the cervical alignment.Sex and age are two influential factors of the total ROM.Sex,age and cervical disc degeneration are influential factors of the segmental ROM.The cervical alignments do not have an impact on total ROM.

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the efficacy and safety of entecavir maleate (ETV) versus ETV in Chinese patients with hepatitis B e antigen(HBeAg)-positive chronic hepatitis B(CHB).</p><p><b>METHODS</b>The patient population of this previously published randomized, double-blind, double-dummy, controlled, multicenter study was expanded by patients in the 0.5 mg/day ETV maleate group (total n = 110) and patients in the 0.5 mg/day ETV group (total n = 108). At treatment weeks 12, 24 and 48, hepatitis B virus (HBV) DNA levels were measured by the Roche Cobas Ampliprep/Cobas Taqman PCR assay. Adverse events (AE) were recorded.</p><p><b>RESULTS</b>As in the original analysis, the two treatment groups showed similar characteristics at baseline. In addition, the results for the all therapeutic effects showed identical trends to the results obtained in the original analysis, including the statistically similar effects of ETV and ETV maleate treatment-induced decreases in mean HBV DNA level at weeks 12, 24, and 48 (ETV: by 4.28, 5.00, and 5.53 log10 IU/ml vs. ETV maleate: by 4.46, 4.99, and 5.51 log10 IU/ml, respectively; all vs. baseline P more than 0.05), achievement of undetectable levels of serum HBV DNA ( less than 20 IU/ml) at week 48 (ETV: 38.18% vs. ETV maleate: 35.19%; P more than 0.05), HBeAg loss rates at week 48 (ETV: 10.91% vs. ETV maleate: 12.96%; P more than 0.05), HBeAg seroconversion rates at week 48 (ETV: 7.77% vs. ETV maleate: 10.38%; P more than 0.05), normalization of alanine aminotransferase at week 48 (ETV: 75.47% vs. ETV maleate: 82.86%; P more than 0.05), and overall incidence of AE (ETV: 18.02% vs. ETV maleate: 17.43%; P more than 0.05).</p><p><b>CONCLUSION</b>Performing analysis of the therapeutic efficacies of entecavir maleate versus entecavir with a larger study population confirmed our original findings of similar efficacy and safety profiles for these two drugs in patients with HBeAg-positive CHB.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the efficacy and safety of entecavir (ETV) maleate versus ETV in Chinese patients with hepatitis B e antigen (HBeAg)-negative chronic hepatitis B (CHB).</p><p><b>METHODS</b>This was a randomized, double-blind, double-dummy, controlled, multicenter study. Patients were randomly assigned to receive 48 weeks of treatment with 0.5 mg/day ETV (group A; n = 26) or 0.5 mg/day ETV maleate (n = 31). Hepatitis B virus (HBV) DNA levels were measured at weeks 12, 24, and 48 by the Roche Cobas Ampliprep/Taqman PCR assay. Adverse events (AE) were recorded.</p><p><b>RESULTS</b>Baseline characteristics were similar between the two groups. At weeks 12, 24, and 48, the mean HBV DNA level had similarly decreased from baseline in both groups (A: by 4.24, 4.61 and 4.88 log10 IU/mL vs. B: 4.01, 4.50 and 4.99 log10 IU/mL, respectively; all P more than 0.05). Patients who achieved undetectable levels of serum HBV DNA (less than 20 IU/mL) at week 48 were similar in the two groups (A: 69.23% vs. B: 80.65%; P more than 0.05). Both groups achieved similar normalization of ALT at week 48 (A: 96.00% vs. B: 83.87%; P more than 0.05). The overall AE incidence was similar for the two groups (A: 22.22% vs. B: 9.38%; P more than 0.05).</p><p><b>CONCLUSION</b>Entecavir maleate and entecavir showed similar efficacy and safety in patients with HBeAg-negative CHB.</p>

ABSTRACT

<p><b>BACKGROUND</b>Recently, new anti-epileptic drugs (AEDs) have been more frequently selected to treat epilepsy. In the present study, we evaluated the dynamic changes of efficacy and safety of three newer AEDs for treating partial epilepsy in China.</p><p><b>METHODS</b>Patients were collected sequentially and were divided into three groups which accepted oxcarbazepine (OXC), lamotrigine (LTG) or topiramate (TPM) therapy. Each group included monotherapy and add-on therapy subgroups. We followed all patients for one year and recorded the indexes of efficacy and safety in detail.</p><p><b>RESULTS</b>A total of 909 patients finished the follow-up observation. No significant difference was found in proportion of patients with > or = 50% reduction, > or = 75% reduction and 100% seizure reduction in the LTG and OXC groups between the first and the second six months. In the TPM group there was a statistical difference between the first and the second six months in proportion of patients with > or = 50% reduction (P = 0.002), > or = 75% reduction (P < 0.0001) and 100% seizure reduction (P = 0.009) in the monotherapy subgroup, and about > or = 75% reduction and 100% seizure reduction in the add-on therapy subgroup (P < 0.0001). The efficacy between the add-on and monotherapy subgroups showed a statistical difference. The safety of the three newer AEDs was good.</p><p><b>CONCLUSIONS</b>The three newer AEDs all showed good efficacy and tolerability for partial epilepsy. And the efficacy can be maintained for at least one year.</p>
