OBJECTIVE:
To provide anatomic data for cochlear implantation, and to find the method of locating lamina spiralis (LS) on the surface of promontory.
METHOD:
Microanatomical study was carried out on 30 sides of human temporal bones by observing and measuring lamina spiralis below promontory, including its location, course and adjacent structures.
RESULT:
(1) The basal turn of lamina spiralis below promontory can be divided into three segments: the hook segment (1.52 +/- 0.16) mm, the anteroinferior round window segment (3.83 +/- 0.37) mm and the forwarding segment (2.70 +/- 0.36) mm by two hinge points of which one was located at anterior of the junction of superior margin and anterior border of RW, and the other was located at anteroinferior of the round window; (2) The plane of round window anteroinferior segment of LS lay (51.00 +/- 5.97) degrees anteroinferior to horizontal segment of the facial nerve and comparative permanently meet posterior margin of'stapes head. Made posterior margin of stapes head as a fixation point and draw a line on promontory lay (51.00 +/- 45.97) degrees anteroinferior to horizontal segment of the facial nerve. This line can be thought as the projection of anteroinferior round window segment of LS on promontory; (3) The width of scala tympani at cochleostomy site on promontory: width of scala tympani at midpoint of superior margin of round window was (0.36 +/- 0.06) mm; width of scala tympani at midpoint of anterior border of round window was (0.97 +/- 0.14) mm; width of scala tympani at 3 mm point of anteroinferior round window segment was (1.24 +/- 0.21) mm.
CONCLUSION
(1) The basal turn lamina spiralis below promontory can be divided into three segments (the hook segment, the anteroinferior round window segment and the forwarding segment) by two hinge points; (2) The projection of anteroinferior round window segment of LS and the features exhibited in its course provide reference for locating the basal turn scala tympani and offer reliable anatomical basis for minimal invasive intervention during cochlear implantation.

Purpose:
Myofibroblastic cancer-associated fibroblasts (myCAFs) are important components of the tumor microenvironment closely associated with tumor stromal remodeling and immunosuppression. This study aimed to explore myCAFs marker gene biomarkers for clinical diagnosis and therapy for patients with bladder cancer (BC).
Materials and Methods:
BC single-cell RNA sequencing (scRNA-seq) data were obtained from the National Center for Biotechnology Information Sequence Read Archive. Transcriptome and clinical data were downloaded from The Cancer Genome Atlas and the Gene Expression Omnibus databases. Subsequently, univariate Cox and LASSO (Least Absolute Shrinkage and Selection Operator regression) regression analyses were performed to construct a prognostic signature. Immune cell activity was estimated using single-sample gene set enrichment analysis whilst the TIDE (tumor immune dysfunction and exclusion) method was employed to assess patient response to immunotherapy. The chemotherapy response of patients with BC was evaluated using genomics of drug sensitivity in cancer. Furthermore, Immunohistochemistry was used to verify the correlation between MAP1B expression and immunotherapy efficacy. The scRNA-seq data were analyzed to identify myCAFs marker genes.
Results:
Combined with bulk RNA-sequencing data, we constructed a two-gene (COL6A1 and MAP1B) risk signature. In patients with BC, the signature demonstrated outstanding prognostic value, immune infiltration, and immunotherapy response. This signature served as a crucial guide for the selection of anti-tumor chemotherapy medications. Additionally, immunohistochemistry confirmed that MAP1B expression was significantly correlated with immunotherapy efficacy.
Conclusions
Our findings revealed a typical prognostic signature based on myCAF marker genes, which offers patients with BC a novel treatment target alongside theoretical justification.

OBJECTIVETo study the genetic polymorphisms of methylenetetrahydrofolate reductase (MTHFR) among the Han, Buyi and Miao populations in Guizhou and to provide genetic data for establishment of the genetic polymorphism bank of Guizhou Minorities.
METHODSThe technique of polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP) was used to detect the genotype and allele frequencies at two mononucleotide sites (677 and 1298) of MTHFR among the Han population in Libo county, the Buyi population in Libo county and the Miao population in Leishan county.
RESULTSAt the site of 677, the T allele frequencies were found to be 22.8%, 16.1%, 10.6%, for the Han, Buyi, Miao populations respectively. At the site of 1298, the C allele frequencies were 28.9%, 39.1%, 48.7% for the Han, Buyi, Miao populations respectively. The frequencies for the combined heterozygote of 677CT/1298AC were 16.66%, 22.7%, 11.1% for the three populations respectively. Moreover, one case with combined homozygote of 677TT/1298CC was seen in the Miao population.
CONCLUSIONThe polymorphisms of the two mononucleotide sites (677 and 1298) of MTHFR are diverse in different populations. The C allele frequencies at the site of MTHFR 1298 of the Miao population in Leishan county and the Buyi population in Libo county are high, and the C allele frequency in the Miao population is higher than those hitherto reported in literature.

Objective :
To investigate the expression and prognosis of urokinase plasminogen activator (PLAU) and v-akt murine thymoma viral oncogene homolog 1 (AKT1) in oral squamous cell carcinoma ( OSCC) and normal tis- sues and the correlation of PLAU and AKT1 in OSCC tissues.
Methods :
The expression levels of PLAU and AKT1 in 70 cases of oral squamous cell carcinoma and 50 cases of normal tissues were detected by immunohistochemical method,and the correlation between PLAU and AKT1 expression and clinicopathological features and prognosis as well as the correlation between PLAU and AKT1 expression in OSCC tissues was analyzed,and the results were fur- ther verified by bioinformatics database.
Results :
The expression of PLAU and AKT1 in OSCC tissues was higher than that in normal tissues (P<0. 05) ,Kaplan-Meier analysis showed that patients with low PLAU and AKT1 ex- pression had longer survival time than those with high AKT1 expression (P<0. 05) ,Spearman rank sum correlation test showed that there was a strong correlation between PLAU and AKT1 expression in OSCC tissues (r = 0. 357,P <0. 05) ,GEPIA bioinformatics database analysis results are consistent with experimental results.
Conclusion
PLAU and AKT1 are highly expressed in OSCC tissues and are associated with poor prognosis of patients.There is a correlation between PLAU and AKT1 in OSCC tissues.
