OBJECTIVETo investigate the expression of a new immunoglobulin gene SNC73 in malignant tumor and normal tissue and its significance.

METHODSExpression level of SNC73 in tumors and normal tissues was determined by reverse transcription-polymerase chain reaction and enzyme-linked immunosorbent assay (RT-PCR-ELISA) in 90 malignant tumors, including colorectal cancer, gastric cancer, breast cancer, lung cancer and liver cancer. Analysis on relation of SNC73 expression with age, sex, site, differentiation grade, depth of invasion and metastasis of colorectal cancer was made to assess the clinical significance of SNC73.

RESULTSMean ratio of SNC73 expression level in normal mucosa and colorectal cancer tissue was 7.134 (P < 0.01). Expression of SNC73 showed no significant difference among gastric cancer, breast cancer, lung cancer or liver cancer as compared with the control normal tissues (P > 0.05).

CONCLUSIONDown-regulation of SNC73 expression is a relatively specific phenomenon in colorectal cancer for which development SNC73 may be a potential genetic marker. The study on relationship of SNC73 expression with development of colorectal cancer is promising.

Objective: The incidence and distribution of positional deformities(PD)were studied by measuring cranial types of infants aged 0-6 months of 3 hospitals in Chongqing, and the recommended values of local PD were discussed. Methods: Data of 3 406 infants with 0-6 months head size measurements were collected from the Second Affiliated Hospital of Army Military Medical University, Yongchuan Maternal and Child Health Care Hospital and Wanzhou Maternal and Child Health Care Hospital from September 1, 2017 to August 31, 2018, cranial vault asymmetry(CVA)and cranial index(CI)were calculated.According to different age groups, observe the distribution of cranial types, and use the current international common diagnostic criteria to understand the incidence of cranial abnormalities, and analyze the distribution of percentile values of CVA and CI in infants in Chongqing. Results: According to the current international standard diagnosis of PD, the incidence of simple brachycephaly was the highest(39.9%)in the overall cranial abnormalities of infants, followed by brachycephaly with plagiocephaly was the second(36.1%), simple plagiocephaly was the lowest(6.9%), and normal cranial type only accounted for 17.1%.The detection rates of plagiocephaly(36.9%)and brachycephaly(67.0%)were the lowest in the 0-2 months group, and the highest in the 3-4 months group(47.3%/83.3%), and then decreased in the 5-6 months group(46.6%/80.2%). Conclusion The basic values of cranial type measurement of full-term infants in chongqing were significantly different from international reports, mainly due to the large CI value.The general international diagnosis standard for positional deformities do not conform to Chinese infants.We suggest that the reference value for positional deformities in this region is as follows: CVA≥0.4 cm is abnormal, of which 0.4 cm≤CVA<0.6 cm for mild plagiocephaly, 0.6 cm≤CVA<1.0 cm for moderate plagiocephaly, CVA≥1.0 cm for severe plagiocephaly; 82%≤CI≤91% is abnormal, of which 91%≤CI<94% for mild brachycephaly; 94% ≤CI<99% for moderate brachycephaly; CI≥ 99% for severe brachycephaly.CI≤82% is scaphocephaly.

Objective:To investigate the clinical characteristics, differential diagnosis, treatments and prognosis of facial nerve hemangioma and schwannoma at genicular ganglion, so as to provide reference for clinical diagnosis and treatments of facial nerve tumor at genicular ganglion.Methods:Clinical data of 13 patients with facial nerve tumors at genicular ganglion confirmed by postoperative pathology in the Ninth People′s Hospital affiliated to Shanghai Jiaotong University School of Medicine from March 2018 to April 2020 were retrospectively analyzed, including seven cases of hemangioma and six cases of schwannoma. There were eight males and five females. Their ages ranged from 20 to 65, with an average age of 40. The course of disease ranged from 3 to 118 months, with an average of 52 months. All the patients underwent preoperative HRCT of the temporal bone and facial nerve dynamic contrast-enhanced(DCE) MRI examinations. All the patients had detailed surgical procedures and at least one-year postoperative follow-up.Results:On HRCT of the temporal bone, (4/7) hemangioma at geniculate ganglion showed characteristic honeycomb appearance, while 6/6 schwannoma and 3/7 hemangiomas showed expansive bone changes. On DCE-MRI, geniculate ganglion hemangioma (7/7) showed characteristic "point-to-surface" enhancement, and schwannoma (6/6) showed characteristic "face-to-surface" enhancement. For five hemangioma-patients with HB-Ⅱ-Ⅳ before surgery, the facial nerve anatomy was completely preserved through transcanal endoscopic approach(TEA), and the facial nerve function improved one year after surgery (two cases of HB-I, two cases of HB-Ⅱ, and one case of HB-Ⅲ). For two patients, with preoperative facial nerve function HB-Ⅴ-Ⅵ, since their tumors was inseparable from the nerves, they were performed with facial nerve anastomosis during the surgery, and the facial nerve function was improved to HB-Ⅳ level one year after surgery. For six patients with meningioma whose facial nerve function was greater than or equal to HB-Ⅲ, based on the preoperative hearing level, the involved segments, and duration of facial paralysis, three of them were conducted surgeries through middle cranial fossa approach, one by translabyrinthine approach, and one via mastoid approach. Two patients among them with complete facial paralysis over three years preoperatively were not performed facial nerve anastomosis after total resections of the tumors, and there was no improvement in facial nerve function one year after surgery. Three patients underwent facial nerve anastomosis after total tumor resections, and their facial nerve function was HB-Ⅲ in one patient, HB-Ⅳ in two patients one year after surgery. One patient (preoperative HB-Ⅲ) had a normal hearing level preoperatively, and the tumor involved the labyrinth segment. To protect the hearing, partial tumor was resected through the middle cranial fossa approach, and facial nerve function improved to HB-Ⅱ one year after surgery.Conclusions:Temporal bone HRCT combined with DCE-MRI are useful for the differential diagnosis of hemangioma and schwannoma at geniculate ganglion and provide references for preoperative clinical decision makings. It is extremely necessary to select the appropriate surgical approach based on the patient′s hearing and involved segments. For geniculate ganglion hemangioma, early surgery can improve the possibilities of anatomical integrity of facial nerve, thereby improving facial nerve function postoperatively.TEA is a kind of surgical method worth consideration, with the characteristics of minimally invasive, favorable postoperative features, and so on. For schwannoma, one-stage functional reconstruction of the facial nerve is recommended during the resection of the tumors because of the inevitable damage to the anatomical integrity of the facial nerve.
