Objective: To investigate the incidence trend of sexually transmitted diseases (STDs) in Yantian District, Shenzhen City, Guangdong Province from 2008 to 2022, and the effects of age, period, and cohort on STDs incidence, so as to provide the basis for formulating control measures for STDs. Methods: Data of reported STDs cases (syphilis, gonorrhea, genital Chlamydia trachomatis infections, condyloma acuminatum and genital herpes) among population aged 15 to 64 years in Yantian District from 2008 to 2022 were collected through the Chinese Disease Control and Prevention Information System. The temporal and population distribution of STDs were descriptively analyzed. Trends in incidence of STDs were analyzed using average annual percent change (AAPC). Impacts of age, period and cohort on the incidence of STDs were analyzed by an age-period-cohort model. Results: A total of 6 156 cases of STDs aged 15 to 64 years were reported from 2008 to 2022, and the average annual incidence was 229.92/105. The overall incidence showed an upward trend (AAPC=2.409%, P<0.05), and an upward trend among females (AAPC=5.846%, P<0.05), but the trend was not statistically significant among males (AAPC=0.193%, P>0.05). The incidence of STDs showed an increasing trend followed by a decreasing trend with the increase of age. The incidence trend among males was consistent with the overall population, reaching its peak in the age group of 30 to 34 years (371.04/105), while the incidence among females showed an increasing trend with the increase of age, peaking in the age group of 60 to 64 years (442.15/105). Compared with 2013-2017, the incidence risk of STDs showed an increasing trend in 2018-2022 (RR=1.349, 95%CI: 1.217-1.495). Compared with the birth cohort of 1975-1979, the incidence risk of STDs in 1980-2005 birth cohort showed an increasing trend, with the highest incidence risk in 2000-2004 birth cohort (RR=4.178, 95%CI: 2.717-6.423). Conclusions The overall incidence of STDs among residents aged 15 to 64 years in Yantian District from 2008 to 2022 appeared a tendency towards a rise. Age, period and cohort all had impacts on the incidence, with a greater effect among females than males.

The seventy-two grid palm technique is an important theoretical source of traditional Chinese medicine hand diagnosis. Starting from the ecological medical model， we analyse the seventy-two grid palm technique， and believe that its diagnosis of human body integrates biological， ecological， psychological， social and other factors， and each factor is based on physiological and pathological theories， and its external social interpretation of the nature of the human body is inseparable from health state. It is proposed that the seventy-two grid palm technique should be integrated with the ecological and natural viewpoints based on the biomedical models or bio-psycho-social medical models， and the research should be conducted from the perspective of the ecological medical model， in order to promote the development of hand diagnosis.

Acute liver injury (ALI) is often caused by virus infection, alcohol, drugs, toxin, and metabolic disorder, and oxidative stress is a common pathophysiological mechanism in the development and progression of ALI and other liver diseases. Hepatocyte function is impaired after ALI, which further causes oxidative stress, and persistent or high-intensive oxidative stress may increase the risk of hepatocyte death and thus result in a series of liver diseases. Oxidative stress is mainly associated with the signaling pathways including nuclear factor erythroid 2-related factor 2 and nuclear factor-kappa B. Therefore, it is of great importance to understand the mechanism of oxidative stress in the development and progression of liver injury and related pathways. This article introduces oxidative system and antioxidative system, oxidative stress and damage factors, and oxidative stress and pathways associated with liver injury, so as to provide a reference for the selection of therapeutic targets for ALI and related clinical research.

【Objective】 To study the technology of separating and purifying C1 esterase inhibitor (C1-INH) by using the waste washing liquid as raw materia during the preparation of human prothrombin complex (PCC) l. 【Methods】 C1-INH was isolated and purified by a two-step method of polyethylene glycol (PEG) 4000 precipitation and cation chromatography. The pH of raw materials and the concentration of PEG4000 were adjusted to investigate the optimal conditions of PEG4000 precipitation method. After PEG was precipitated and centrifuged, the supernatant is treated as the loading solution for cation exchange chromatography, using Fractogel EMD SE HiCap(M) gel and CM Sepharose FF gel for ion exchange chromatography. The most suitable gel and separation conditions were selected by comparing the C1-INH antigen yield, activity yield and specific activity. 【Results】 Under the condition of pH 6.1, when the mass fraction of PEG4000 was 14%, the recovery rate of C1 esterase inhibitor was close to 70%, and the removal rate of ceruloplasmin was more than 95% after stirring for 10 minutes. As fractogel EMD SE HiCap(M) gel was used for cation exchange chromatography, when the eluent salt concentration was 0.25 M sodium chloride, the activity yield of C1 esterase inhibitor was greater than 80%, and the specific activity was greater than 5 IU/mg. 【Conclusions】 Using the waste washing liquid as the raw material during the preparation of PCC, the C1 esterase inhibitor with high specific activity can be prepared through PEG precipitation and purification by Fractogel EMD SE HiCap(M) ion exchange chromatography.

The clinical data of a case of neonatal bacterial meningitis complicated with posterior fossa subdural empyema in the West China Second University Hospital in December 2019 were retrospectively analyzed.The 3-day-old male newborn was admitted for jaundice with decreased intake for 1 day.Examinations on admission showed increased C-reactive protein.The count of karyocytes in cerebrospinal fluid (CSF) significantly increased, which were mainly neutrophils, and pyocytes could be found.The protein content in CSF increased, while that of glucose decreased.Both CSF culture and blood culture detected the presence of Escherichia coli.Enhanced magnetic resonance imaging (MRI) of the head indicated large abnormal signals in bilateral occipital extra-cerebellar spaces.T1-weighted images presented mixed low and high signals, and T2-weighted images presented high signals, and marginal enhancement was observed after enhancement.After 6 weeks of antibiotic treatment using Meropenem combined with Ceftazidime, the CSF index of the newborn patient returned to normal, and the subdural empyema of the posterior fossae subsided.Bacterial meningitis complicated with subdural empyema of posterior fossa is a rare and critical disease of the central nervous system.It is easily misdiagnosed due to the atypical clinical manifestations and early imaging features.The disease requires an adequate course of anti-infective treatment.Surgical removal of the empyema should be performed if the anti-infective treatment is unresponsive.

Objective:To systematically evaluate the rehabilitation efficacy of core stability training versus general exercises or manual therapy in patients with non-specific low back pain.Methods:The Medline, EMBASE, PubMed, Cochrane Central Register of Controlled Trials (CENTRAL) , PsycINFO, China Biology Medicine (CBM) , CNKI, VIP and Wanfang database were searched by computer, and the retrieval time was from the establishment of the database to 20th October, 2018. All randomized controlled trials (RCT) and clinical control studies of the rehabilitation effects of core stability training on patients with non-specific low back pain were collected.

And the data were extracted for Meta-analysis using Revman 5.3 software.Results:A total of 14 articles were included, all of which were RCTs. The results of Meta-analysis showed that the comparison of pain improvement between core stability training group and general exercise training group was ( Z=4.67, P<0.001) [ OR=1.01, 95% CI (-1.43, -0.59) ], and the evidence showed statistical significance ( P<0.05) . The comparison of Oswestry Disability Index scores of patients after core stability training and general exercise training was ( Z=5.03, P<0.01) [ OR=-7.18, 95% CI (-9.98, -4.38) ], and the evidence showed statistical significance ( P<0.05) . The comparison results of other indicators were not statistically significant ( P>0.05) . Conclusions:The core stability training group and manual therapy group can effectively reduce pain in patients with non-specific low back pain, and core stability training can promote the relief of dysfunction in patients with non-specific low back pain, and core stability training should be encouraged as part of musculoskeletal rehabilitation for patients with non-specific low back pain.

Objective: Alport syndrome was an inherited kidney disease caused by the mutation of COL4A3, COL4A4, or COL4A5. Whole-exome sequencing was used to detect the mutations on these genes for the molecular diagnosis of Alport syndrome. Methods: A 6-year-old girl found accidentally with microscopic hematuria at the age of 4. The clinical data and blood sample of the family including proband, parents, brothers, and sisters were collected. Whole exome sequencing was conducted using their genomic DNAs. Results: A novel heterozygous frameshift mutation c.1826delC (p.Pro609Glnfs*44) was found in the exon 25 of the COL4A4 (NM_000092) in the proband, the father, and the sister, showing an autosomal dominant inheritance pattern of Alport syndrome. This mutation of COL4A4 was confirmed by mutation analysis, and the mutation of c.1826delC was verified by Sanger sequencing. No mutations on COL4A3 and COL4A5 were detected in this family. And the mother and brother are normal wide-type. Conclusions This novel mutation is a valuable addition to the current genetic profile of Alport syndrome, and provide us a better understanding of the disease. Whole-exome sequencing is a power tool to identify the novel mutations of inherited disease and contribute to the molecular diagnosis of disease.
