Public health issues are drawing more and more attention from all sides of the society,and they refer to many aspects of social life.The approaches to achieving the goal of public health will be discussed in this article,including economic development,improvement of legislation and system construction,strengthening the directing function of public opinion and the macro-control function of government,and the strength of morality.

OBJECTIVE: To validate the diagnosis of an infant with elevated urine 3-methylglutaconic acid (3-MGA) through sequencing of the CLPB gene. METHODS: Genomic DNA of the infant was sequenced by next generation sequencing (NGS), and candidate pathogenic variants were verified by Sanger sequencing and bioinformatics analysis. RESULTS: NGS has revealed that the infant has carried a c.1085G>A (p.Arg362Gln) and a c.1700A>C (p.Tyr567Ser) of the CLPB gene, which were respectively inherited from her parents. Among these, c.1085G>A (p.Arg362Gln) is a novel variant which was unreported previously, and based on the ACMG guidelines, it was predicted to be a possible pathogenic variant. CONCLUSION Compound heterozygous variants c.1085G>A (p.Arg362Gln) and c.1700A>C (p.Tyr567Ser) of the CLPB gene probably underlay the disease in this infant. Genetic testing has confirmed the diagnosis.

OBJECTIVE: To explore the genetic basis for a child featuring congenital insensitivity to pain (CIP). METHODS: Targeted capture and next generation sequencing (NGS) was carried out for the proband. Suspected pathogenic variants were confirmed by Sanger sequencing of the proband and his parents. RESULTS: The proband was found to harbor compound heterozygous variants of SCN9A gene, namely c.1598delA (p.N533Ifs*31) and c.295_296delCGinsAT (p.R99I), which were respectively inherited from his father and mother. Both variants were predicted to be pathogenic, and neither was reported previously. CONCLUSION The compound heterozygous variants of the SCN9A gene probably underlay the CIP in this child. Above finding has enabled genetic counseling for this family.

Objective:To evaluate the value and efficacy of microscope-assisted minimally invasive anterior lumbar discectomy and zero-profile fusion (ALDF) for lumbar degenerative diseases.Methods:Anterior lumbar distractors were designed to maintain the distraction of intervertebral space and expose the posterior edge of the intervertebral space. From June 2018 to December 2020, 41 cases of lumbar degenerative diseases were treated with this operation, including 19 men and 22 women, aged 29-71 years old (average 42.1 years old). All patients had intractable low back pain. Imaging examination showed lumbar disc degeneration with narrow intervertebral space, including disc herniation with Modic changes in 7 cases, spinal stenosis with instability in 16 cases and spondylolisthesis in 18 cases. The involved levels included L 2,3 in 1 case, L 3,4 in 3 cases, L 2-L 4 in 1 case, L 4,5 in 17 cases and L 5S 1 in 19 cases. An incision was taken that was pararectus for L 2-L 4 and transverse for L 4-S 1, with the intervertebral disc exposed via extraperitoneal approach. The intervertebral space was released and distracted after discectomy in intervertebral space, and self-made distractors were used to maintain the space. Under microscope, the herniation, posterior annulus and osteophyte were removed for sufficient decompression, with a suitable self-anchoring cage implanted into the intervertebral space. The visual analogue score (VAS), Oswestry dysfunction index (ODI), intervertebral space height, lordosis angle and spondylolisthesis rate were evaluated. Results:Operations were performed successfully in all the patients. The operation time was 70-120 min with an average of 90 min, and the intraoperative blood loss was 15-70 ml with an average of 30 ml. No severe complication such as nerve or blood vessel injury occurred. The patients were followed up for 12 to 36 months, with an average of 18 months. At the last follow-up, VAS decreased from 6.4±2.3 to 1.1±0.9, and ODI decreased from 44.9%±16.9% to 5.8%±4.7%. Intervertebral space height recovered from 7.2±2.8 mm to 12.1±2.1 mm and lordosis angle recovered from 6.9°±4.8° to 10.1°±4.6°. X-ray showed significant recovery of intervertebral space height, lordosis angle and spondylolisthesis rate, with obvious interbody fusion and no displacement of cage. For 18 patients of spondylolisthesis, the slippage recovered from 16.6%±9.3% to 7.6%±5.3%, with an average improvement of 54.2%.Conclusion:Microscope-assisted minimally invasive ALDF can provide sufficient decompression and zero-profile fusion for lumbar degenerative diseases with satisfactory results during short-term follow-up.

Objective:To evaluate the safety and validity of enriched autologous bone marrow mesenchymal stem cells (BMSCs) and annular suture for repairing defect after lumbar discectomy.Methods:Enrichment of autologous BMSCs: autologous bone marrow blood was collected from 5 patients undergoing lumbar surgery, and nucleated cells were enriched on gelatin sponge particles by selective cell retention technique. From October 2016 to March 2019, 109 patients with lumbar disc herniation underwent discectomy with mobile microendoscopic discectomy technique, including 61 males and 48 females, aged 24-59 years. Discectomy group: 26 cases received simple discectomy. Suture group: 39 cases received annular suture after discectomy. BMSCs+suture group: 44 cases received intradisc transplantation of gelatin sponge particles enriched with autologous BMSCs and annular suture after discectomy. The perioperative conditions were recorded, with visual analogue scale (VAS), Oswestry dysfunction index (ODI), Pfirrmann grade of disc degeneration, disc height and degree of herniationevaluated after operation.Results:In enrichment test with flow cytometry, the enrichment multiple of nucleated cells and target cells was 6.4±0.9 and 4.2±0.6 respectively, and BMSCs grew well in vitro. The operation time was 35-55 mins. 7 cases in the suture group were transferred to the discectomy group and 10 cases in the BMSCs+suture group were transferred to BMSCs group due to unsuccessful suture. There were no significant differences in VAS, ODI, Pfirrmann grade of disc degeneration, disc height and degree of herniation among the groups. There was no significant difference in intraoperative bleeding, postoperative drainage and length of hospital stay. The incision was healed without redness and swelling. 18 patients were followed up for 6 months, and 91 cases were followed up for 1-3 years (25.0±5.6 months). There was no interbody fusion, heterotopic ossification or infection during follow-up. VAS and ODI decreased significantly after operation in all patients. At final follow-up, the VAS improvement rate of BMSCs+suture group (81.7%±7.9%) was higher than discectomy group (73.0%±8.9%), suture group (74.0%±6.9%) and BMSCs group (75.3%±8.4%); the ODI improvement rate of BMSCs+suture group (91.9%±8.8%) was higher than discectomy group (86.2%±8.1%) and suture group (86.4%±5.5%). According to MRI, the Pfirrmann grade of disc increased 0.7 in discectomy group, 0.6 in suture group, while it did not increased significantly in BMSCs+suture group and BMSCs group, and the progress of Pfirrmann grade in BMSCs+suture group and BMSCs group were lighter than discectomy group and suture group.The disc height decreased in each group, the loss rate of disc height in BMSCs+suture group (17.2%±4.3%) was less than discectomy group (29.3%± 6.3%) and suture group (20.6%±5.7%); and suture group was less than discectomy group. The degree of herniation was reduced by more than 50% in all groups, while 1 case in discectomy group had herniation without clinical symptoms.Conclusion:Autologous BMSCs and annulus suture are safe and effective in repairing the defect after lumbar discectomy, which may help to slow down the degeneration of intervertebral disc.

OBJECTIVE: To explore the clinical and genetic characteristics of a very early-onset inflammatory bowel disease (VEO-IBD) type 28 child with atypical clinical manifestations. METHODS: A VEO-IBD type 28 child with atypical clinical manifestations admitted to the Department of Neonatology, Children's Hospital Affiliated to Shandong University on November 5, 2021 was selected as the study subject. Clinical data of the child was collected. Peripheral venous blood samples of the child and his parents were collected for high-throughput sequencing. Candidate variants were verified by Sanger sequencing and bioinformatic analysis. RESULTS: The child, a 50-day-old male, had manifested bronchitis, ulcerative stomatitis, eczema and slightly loose stool. High-throughput sequencing revealed that he has harbored compound heterozygous variants of the IL-10RA gene, namely c.299T>G (p.V100G) and c.301C>T (p.R101W), which were inherited from his father and mother, respectively. Bioinformatic analysis showed that both variants have been recorded in the HGMD database, though the c.299T>G variant has not been included in the gnomAD, 1000 Genomes, ExAC and ESP6500 databases, while the c.301C>T variant has a low population frequency. Both variants were predicted to be deleterious by the online software including SIFT, PolyPhen-2 and Mutation Taster. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), both variants were predicted to be pathogenic (PS3+PM2_Supporting+PP3). CONCLUSION The c.299T>G and c.301C>T variants of the IL-10RA gene probably underlay the VEO-IBD type 28 in this child. Above finding has expanded the phenotypic spectrum of VEO-IBD type 28 due to variants of the IL-10RA gene and provided a reference for the clinical diagnosis of this disease.
