MethodsAccording to the systematic review of text and opinion （SrTO） process developed by the Joanna Briggs Institute （JBI） in Australia， this paper determined literature screening criteria by searching China National Knowledge Infrastructure （CNKI）， VIP， Wanfang， and China Biomedical Literature Database. Information was extracted after literature screening， and quality evaluation was conducted using the JBI Narrative， Text， and Opinion Systematic Review Strict Evaluation Checklist. The JBI Narrative， Opinion， Text Evaluation， and Review Tool Summary Table was used for information synthesis， and data analysis and display were conducted in the form of text and charts. ResultsThe 146 articles related to 39 renowned experts and 19 articles related to 10 schools of thought were included. Research has found that contemporary experts and schools in traditional Chinese medicine gynecology consider blood stasis as the core pathogenesis in understanding the etiology and pathogenesis of two diseases and related infertility. Their viewpoints varied from multiple aspects such as clinical symptom characteristics， meridian circulation location， pathological product evolution， disease duration， emotional psychology， lifestyle habits， preference for food and drink， innate endowment， and acquired injury. In terms of treatment， it was advocated to divide the stage， treat according to different types， adapt to the times， integrate nature and humans， and combine multiple methods to treat comprehensively when necessary. It was also recommended to skillfully use insects， make good use of classic formulas and small prescriptions， pay attention to protecting the spleen and stomach and regulating emotions， and make good use of self-formulated empirical formulas for internal or external use. Besides， individualized long-term management of patients was also advocated. ConclusionThis study applies the SrTO process to systematically summarize the academic ideas of contemporary renowned experts and schools in traditional Chinese medicine gynecology regarding the causes， mechanisms， diagnosis， and treatments of endometriosis， providing a scientific and standardized reference for future theoretical exploration.

Objective To understand the prevalence and risk factors of hyperuricemia in electronics factory workers in Wuhan, and to provide evidence for the health protection of electronics factory workers. Methods A total of 1 415 employees in an electronics factory in Wuhan were selected as the research subjects, and the physical examination and determination of various biochemical indicators, as well as questionnaire survey were carried out. Results The detection rate of hyperuricemia among workers in the electronics factory in Wuhan was 32.43%, with 36.33% for men and 14.11% for women, and the difference was statistically significant ( χ²＝46.077，P＜0.001). The detection rate of hyperuricemia was the highest (33.77%) among those with university or college education, followed by graduate students and above (31.50%). Compared with subjects with good lifestyle habits, people with drinking habits had higher hyperuricemia detection rate (49.38%), and the difference was statistically significant (P =0.001). The detection rates of hyperuricemia in those with central obesity and elevated alanine aminotransferase were 48.23% and 61.29%, respectively, which were significantly higher than those in the subjects without the above diseases (26.91% and 27.21%, respectively), and the differences were statistically significant (P <0.001). Obese people had the highest detection rate of hyperuricemia (66.95%), followed by overweight people (43.75%), and the difference was statistically significant (P <0.001). Multivariate logistic analysis showed that alcohol drinking (OR=1.836, 95% CI=1.139-2.961, P =0.013) and body mass index ≥ 24 kg/m² (OR=2.175, 95% CI=1.686 -2.806, P <0.001) were risk factors for hyperuricemia in electronic factory workers. Elevated alanine aminotransferase (ALT) was significantly correlated with hyperuricemia (OR=2.964, 95%CI=2.146-4.095 , P <0.001). Female gender was a protective factor for hyperuricemia in workers in the electronics factory (OR=0.441, 95%CI=0.297-0.653 , P <0.001). Conclusion The detection rate of hyperuricemia among workers in an electronics factory in Wuhan is high, and the detection rate of hyperuricemia in men is higher than that in women. Alcohol consumption, overweight and obesity will increase the risk of hyperuricemia. Elevated ALT is associated with hyperuricemia. Maintaining an ideal body mass index and establishing a good lifestyle play an important role in preventing hyperuricemia.

Objective:To investigate the effect of different administration methods of recombinant human prourokinase (rhPro-UK) during emergency percutaneous coronary intervention (PCI) on myocardial perfusion and prognosis of patients with acute ST segment elevation myocardial infarction (STEMI).Methods:The clinical data of 132 patients with STEMI who underwent emergency PCI in the Military Hospital of the 71st Army Group of the Chinese People′s Liberation Army from August 2017 to August 2022 were analyzed retrospectively. Among them, 66 patients treated with rhPro-UK injection after the guide wire passed through the coronary artery lesion, balloon dilation and stent placement were included in group A. The other 66 patients treated with rhPro-UK injection once after the guide wire passed through the coronary artery lesion were included in group B. The two groups were compared in terms of PCI conditions, target vessel perfusion status [corrected TIMI frame count (CTFC) and blood flow (thrombolysis in myocardial infarction, TIMI) grade], myocardial perfusion status [TIMI myocardial perfusion grade (TMPG), ST segment regression rate (STR) at 90 min after operation and the incidence of no reflow/slow flow (NR/SF)], cardiac function indicators [left ventricular end diastolic volume (LVEDV), left ventricular end systolic volume (LVESV) and left ventricular ejection fraction (LVEF)], the incidence of major adverse cardiovascular events (MACE), and the incidence of bleeding events.Results:There were no statistically significant differences between the two groups in terms of the distribution of culprit blood vessels, intubation methods, and number of stents implanted ( P>0.05). After treatment, the proportion of TIMI blood flow grade 3 in the group A was higher than that in the group B:99.97% (64/66) vs. 87.88% (58/66). CTFC of the two tgroups decreased, and CTFC of group A was lower than that of group B: (23.49 ± 4.27) frames vs. (27.14 ± 4.83) frames ( P<0.05). The proportion of TMPG grade 3 in group A was significantly higher than that in group B: 95.45% (63/66) vs. 83.33% (55/66)( P<0.05). STR in group A was significantly higher than that in group B: 95.45% (63/66) vs. 83.33% (55/66)( P<0.05). The incidence of NR/SF in group A was lower than that in group B: 3.03% (2/66) vs. 14.29% (10/66)( P<0.05). There were no statistically significant differences in LVEDV or LVESV between the two groups before and after treatment ( P>0.05). After 1 month of treatment, LVEF of the two groups increased, and LVEF of group A was higher than that of group B: (71.08 ± 6.38) % vs. (66.24 ± 6.49) % ( P<0.05). After treatment, the incidence of MACE in group A was lower than that in group B: 6.06%(4/66) vs. 13.64%(9/66) ( χ2 = 2.13, P = 0.144). There was no statistically significant difference in the incidence of bleeding events between the two groups ( P>0.05). Conclusions:For patients with STEMI undergoing PCI, fractional injection of rhPro-UK can better improve myocardial perfusion, reduce the incidence of MACE, and effectively improve the prognosis, compared with one-time injection of rhPro-UK.

Objective To investigate the predictive value of preoperative blood inflammatory markers for the recurrence risk in patients with basal cell carcinoma(BCC).Methods A total of 225 patients with BCC were divided into the high-risk recurrence group(155 cases)and the low-risk recurrence group(70 cases).General information and preoperative hematological indicators were collected in the two groups of patients.The neutrophil-to-lymphocyte ratio(NLR),lymphocyte-to-monocyte ratio(LMR),systemic inflammation marker(SIM)and platelet-to-lymphocyte ratio(PLR)were calculated.Receiver operating characteristic(ROC)curves were used to determine the predictive value of hematological markers with statistically significant differences between the two groups for BCC recurrence and to establish optimal cutoff values.Univariate and multivariate Logistic regression analyses were conducted to identify factors influencing BCC recurrence.A multivariate Logistic regression model was established to predict the recurrence risk of BCC.Area under the curve(AUC)and the Hosmer-Lemeshow test were used to evaluate the prediction efficiency and goodness-of-fit of the model.Results ROC analysis identified that optimal cutoff values for LMR and SIM were 5.12 and 0.86,respectively.Univariate Logistic regression analysis showed that LMR,SIM,ulceration at the primary tumor site,UV exposure and tumor maximum diameter were factors influencing BCC recurrence.Multivariate Logistic regression revealed that SIM≥0.86,tumor maximum diameter≥2.0 cm and UV exposure were risk factors for BCC recurrence,while LMR≥5.12 had a protective effect.The Logistic prediction model for BCC recurrence risk was Logit(P)=-1.598-1.517×LMR+1.323×SIM+2.406×UV exposure+3.465×tumor maximum diameter,with good model fit(P=0.725)and an AUC of 0.869(95%CI:0.822-0.917)for predicting BCC recurrence risk.Conclusion Monitoring preoperative LMR and SIM levels can assist in assessing the risk of recurrence in BCC patients and provide important guidance for clinical decision-making.

Objective To study the influence of implant depth and scanning rod lengths on the accuracy of digital impression for single-tooth implant restoration of the mandibular posterior teeth.Methods Five standard dental cast models with missing right mandibular first molar(46)were prepared with the subgingival implant depths of 0,1,3,5 and 7 mm.ITI RC and ITI RC H11 scanning rods were connected to the replacement body and placed into the seating tract for scanning.The reference data were obtained using a 3D dental scanner,and the experimental data were obtained by 10 scans of each model using a digitized intraoral scanner.Geomagic Wrap 2021 was used to analyze the model data to test the trueness and precision of the models.Results The trueness did not differ significantly among the groups(P>0.05).The implant depth of 1 mm achieved the highest impression precision(66.81±2.45 μm),and the depth of 0 mm resulted in a significantly lower precision(95.60±3.04 μm)than the depth of 1 and 3 mm.Starting from the subgingival depth of 1 mm,the precision of the scan decreased progressively with the increase of the implant depth.At the subgingival implant depth of 5 or 7 mm,the use of an extended rod significantly improved the scan precision.Conclusion For single-tooth implant restoration of the mandibular posterior teeth,the implant depth can substantially affect the accuracy of digital impression,which decreases as the implant depth increases.For a deep implant,the use of a longer scanning rod can improve the scanning accuracy.

Despite decades of research,cancer continues to be a major global health concern.The human mouth appears to be a multiplicity of local environments communicating with other organs and causing diseases via microbes.Nowadays,the role of oral microbes in the development and progression of cancer has received increasing scrutiny.At the same time,bioengineering technology and nanotechnology is growing rapidly,in which the physiological activities of natural bacteria are modified to improve the therapeutic efficiency of cancers.These engineered bacteria were transformed to achieve directed genetic reprogramming,selective functional reorganization and precise control.In contrast to endotoxins produced by typical genetically modified bacteria,oral flora exhibits favorable biosafety characteristics.To outline the current cognitions upon oral microbes,engineered microbes and human cancers,related literatures were searched and reviewed based on the PubMed database.We focused on a number of oral microbes and related mechanisms associated with the tumor microenvironment,which involve in cancer occurrence and development.Whether engineering oral bacteria can be a possible application of cancer therapy is worth consideration.A deeper understanding of the relationship between engineered oral bacteria and cancer therapy may enhance our knowledge of tumor pathogenesis thus providing new insights and strategies for cancer prevention and treatment.

In order to understand the prevalence and genetic variation of H9N2 subtype avian influ-enza virus in Shandong,a total 492 tracheal and lung tissue samples collected from chicken farms with respiratory symptoms in partial areas in Shandong were detected by H9 subtype AIV real-time RT-PCR,and the positive samples were inoculated with chicken embryos for two generations.Whole genome sequences of the positive strains by applying Illumina Miaseq platform,and genetic evolution and mutation at positions associating with viral pathogenicity and transmissibility were analyzed.The results showed that there were 72 samples were positive for H9 subtype AIV among the 492 samples,with a positive rate of 14.63％.Thirty-four strains of H9 subtype AIV were ob-tained from the positive samples after passing through chicken embryo,meanwhile,the 34 isolates were all H9N2 subtype AIV by whole genome sequencing analysis.By analyzing the evolutionary tree of HA and NA genes,HA and NA genes of the 34 H9N2 AIV strains belonged to Y280-like branch and F/98-like branch,respectively.Meanwhile,based on above branches,there were obvious time node subbranch,which one was"isolates before 2013",another one was"isolates after 2013".The HA cleavage sites of thirty-four H9N2 strains were all 325PSRSSR↓GLF333,which met the se-quence characteristics of the lowly pathogenic avian influenza virus,and the HA receptor binding site 226 amino acid was leucine,which had the characteristics of blinding to a-2,6 mammalian sialic acid receptors.Among the internal amino acid sites that are key to mammalian adaptation,all strains had an I368V mutation in the PB1 gene that enhanced viral transmissibility in mammals and the PB2 genes of some strains were mutated to enhance the mammalian adaptation of I292 V and A588 V.The above results illustrated that the H9N2 subtype AIV gene segments in Shandong have different degrees of recombination and gene variation,so it is necessary to strengthen the monito-ring of virus variation.

Objective:To observe and analyze the ocular clinical features and pathogenic genes of Alstr?m syndrome (ALMS).Methods:A retrospective clinical study. From October 2020 to July 2022, 3 patients and 5 normal family members from 2 families affected with ALMS who visited in the Ophthalmology Department of Henan Children's Hospital were enrolled in the study. These 2 families were without blood relationship. The medical history and family history were inquired. Best corrected visual acuity (BCVA), fundus color photography, full-field electroretinogram (ERG), frequency domain optical coherence tomography (OCT) and systemic examination were performed. 3 ml peripheral venous blood of patients and their family members were collected, and the whole genomic DNA was extracted. The second generation sequencing analysis was performed on these members. The suspected pathogenic mutation sites were verified by Sanger, and the pathogenicity of the gene mutation sites were determined by bioinformatics analysis.Results:Three patients from two families all developed nystagmus and photophobia in infancy. In the family 1, the BCVA of both eyes of the proband was no light perception. The fundus examination revealed vascular attenuation and retinal pigment abnormality. OCT showed retinal thinning, loss of photoreceptor layer and atrophy of the retinal pigment epithelium layer. ERG examination showed extinguished. The BCVA of the proband’s younger brother was 0.04 in the right eye and 0.02 in the left eye. The fundus examination revealed vascular attenuation but the pigment distribution was roughly normal. OCT showed blurred photoreceptor layers in both eyes. ERG examination showed extinguished. Two patients developed sensorineural deafness, obesity, acanthosis nigricans, insulin resistance/diabetes, and abnormal liver function. In addition, the proband also had left heart enlargement, hyperlipidemia and abnormal kidney function. The results of genetic testing showed that the proband and his younger brother had compound heterozygous mutations in exon 8 (c.1894C>T/p.Gln632*, M1) and exon 10 (c.9148_9149delCT/p.Leu 3050 Leufs*9, M2) of ALMS1, which were both known mutations. The father of the proband was a carrier of M1 and the mother of the proband was a carrier of M2. The proband of the family 2 had a normal fundus at 23 months old. The amplitude of ERG b wave under the stimulation of the dark adaptation 0.01 and a, b wave under the stimulation of dark adaptation 0.3 were all mild reduced. The amplitude of ERG a, b wave under the stimulation of the light adaptation 0.3 was severity decreased. At 4 years old, the BCVA was 0.01 in the right eye and 0.05 in the left eye. The fundus examination revealed vascular attenuation and bilateral blunted foveal reflex. In addition to severely diminished of a, b wave under the stimulation of dark adaptation 0.3, the rest showed extinguished. There were no systemic abnormalities. The results of genetic testing showed that the proband had compound heterozygous mutations in exon 11 (c.9627delT/p.Pro3210Glnfs*22, M3) and exon 5 (c.1089delT/p.Asp364Ilefs*13, M4) of ALMS1, which were both novel mutations. The father of the proband was a carrier of M3 and the mother of the proband was a carrier of M4. Conclusions:Nystagmus and photophobia are often the first clinical manifestations of ALMS. In the early stage, the fundus can be basically normal. As the disease progresses, the fundus examination reveals vascular attenuation and retinal pigment abnormality, and the reflection of the fovea is unclear. OCT shows the photoreceptor cell layers are blurred or even lost. The final ERG is extinguished. M1, M2, and M3, M4 compound heterozygous mutations may be the pathogeny for family 1 and family 2, respectively.
