OBJECTIVES:
To investigate the subcellular localization and biological functions of transmembrane protein 240 (TMEM240).
METHODS:
NCBI BLAST and TMHMM bioinformatics software were used for protein sequence analysis and prediction of transmembrane domain of TMEM240. Brain tissues from male C57BL/6 mice (18-20 days old) were examined for distribution of TMEM240 using in situ hybridization, and qPCR and Western blotting were used to detect TMEM240 expression in different mouse tissues and in cortical neurons at different time points (n=3). In the in vitro experiment, HepG2 and Neuro-2a cells were transfected with plasmids for overexpression of TMEM240, and subcellular localization of TMEM240 was analyzed using cell imaging. In primary cultures of cortical neurons isolated from C57BL/6 mice, TMEM240 expression and its biological functions were investigated using qPCR, Western blotting, and immunofluorescence staining.
RESULTS:
Human and mouse TMEM240 proteins share a 97.69% similarity in the protein sequences, and both are transmembrane proteins with two transmembrane domains. TMEM240 mRNA and protein were highly expressed in mouse brain tissues and cortical neurons. In isolated mouse cortical neurons, TMEM240 expression reached the peak level after primary culture for 9 days and distributed in scattered spots within the cells. In HepG2 cells, TMEM240 was characterized as intracellular membrane structures and showed 80% colocalization with peroxisomes. In Neuro-2a cells, TMEM240 overexpression caused significant enhancement of the expressions of Rho GDP dissociation inhibitor β (ARHGDIB) at both the mRNA and protein levels.
CONCLUSIONS
TMEM240 is a novel intracellular subcellular structure specifically expressed in neurons with significant potential for targeted cellular function regulation.

This paper summarized Professor PENG Peichu's experience in the differentiation and treatment of prostate cancer in three phases and four stages. It is considered that prostatic cancer is categorized into root deficiency and branch excess, with depletion of healthy qi as the root, and the accumulation of cancer toxin as the minifestation. Clinical diagnosis and treatment of prostatic cancer can be divided into three phases and four stages according to the exuberance and decline of pathogenic and healthy qi and the changes of deficiency and excess of yin and yang. In the initial accumulation phase of cancer toxin (yang excess stage), the key pathogenesis is the accumulation of dampness, heat and static blood, and internal generation of cancer toxin, and the treatment should be resolving toxins, fighting cancer and dispelling yang excess. In the phase of healthy qi deficiency and toxin accumulation (yin deficiency stage), with the lung and kidney yin deficiency, dampness, heat and static toxin accumulation as the key pathogenesis, the treatment should be centered on mutual generation between metal and water to nourish kidney yin, supplemented with the method of clearing heat and draining dampness, activating blood and resolving toxins, for which self-made Nanbei Formula(南北方)is usually used. In the phase of yang deficiency and cold stagnation (yang deficiency stage and yin excess stage), with the spleen and kidney yang deficiency, cold dampness stagnation, static heat and toxin accumulation as the key pathogenesis, the treatment should be warming and tonifying spleen and kidney to dissipate cold accumulation; for deficiency of both yin and yang, and excess pathogen obstruction, modified Yanghe Decoction(阳和汤) is recommended, while for yang deficiency, cold congealing and blood stasis, self-made Wenshen Sanjie Formula(温肾散结方) can be used, and for cold dampness binding with cancer toxin, and cold complex with heat, self-made Quanan Formula (泉安方) is advised.

BACKGROUND:With the progress of minimally invasive procedures of the spine,endoscopic lumbar decompression has been widely used in the treatment of lumbar disc herniation.The indications of different endoscopic surgical approaches are different,and the decision of the specific operation plan needs to be combined with the actual situation and the choice of clinical surgeons. OBJECTIVE:To investigate the short-term effect in treatment of single-level lumbar disc herniation by percutaneous endoscopic visual trephine arthroplasty. METHODS:Ninety patients with single-level lumbar disc herniation admitted to Affiliated Hospital of Xuzhou Medical University from January 2019 to December 2021 who met the inclusion criteria were included in this study.According to different approaches of percutaneous endoscopic visual trephine arthroplasty,they were divided into transforaminal approach group(control group,n=48 cases)and translaminar approach group(trial group,n=42 cases).The general information of patients in the two groups was recorded,including sex,age,disease course,body mass index,incision length,operation time,intraoperative fluoroscopy times,length of hospital stay,and amount of blood loss.Visual analog scale score of pain and Japanese Orthopaedic Association score at different follow-up stages were assessed.The modified MacNab standard was used to evaluate the clinical outcome at the last follow-up,and the postoperative complications and recurrence rate were measured. RESULTS AND CONCLUSION:(1)The operation time and intraoperative fluoroscopy times of the trial group were less than those of the control group,and the difference was statistically significant(P<0.05).However,there were no significant differences in intraoperative blood loss,incision length,and hospital stay between the two groups(P>0.05).(2)There was no significant difference in visual analog scale score of pain and Japanese Orthopaedic Association score between the two groups before surgery(P>0.05).However,visual analog scale of pain and Japanese Orthopaedic Association score were significantly improved 1 week,3,6,and 12 months after surgery(P<0.05).(3)At the last follow-up,the good and good rate of modified MacNab standard was 94%in the control group and 95%in the trial group.(4)In the control group,one patient still felt back and leg pain after surgery,underwent open surgery,and recovered well after surgery without obvious sequelae.There were no postoperative complications or recurrent cases in the trial group.(5)It is concluded that both percutaneous transforaminal approach and interlaminar approach have good short-term clinical efficacy and high patient satisfaction in the treatment of single-level lumbar disc herniation,but the time of the interlaminar approach is shorter and has less intraoperative fluoroscopy times.
