Objective To investigate effects of hyperbaric oxygen (HBO) therapy on C-reactive protein (CRP) and tumor necrosis factor-α (TNF-α) levels in patients with moderate or severe traumatic brain injury (TBI)and to analyze its therapeutic efficacy. Methods One hundred and eight patients with moderate or severe TBI were randomly divided into a control group (54 cases) and an HBO adjunctive therapy group (HBO group, 54 cases).Both groups received essential neurosurgical treatment and conventional drug treatment, and the HBO group was given one session of HBO therapy in addition. Serum CRP and TNF-α were detected, and the scores on the Glasgow coma scale (GCS) were measured before and after treatment. CRP was detected by turbidimetric immunoassay and TNF-α using ELISA. Glasgow outcome scale (GOS) scores were evaluated in a follow-up 6 months after injury. Results Average CRP, TNF-α and GCS measurements showed no statistically significant difference between the groups before treatment. After treatment, CRP and TNF-α were significantly lower and GCS scores significantly better in both groups, but patients in the HBO group were, on average, significantly better than the controls on all three measures.Six months later, GOS evaluation gave a significantly larger number of patients with a better prognosis in the HBO group compared with the controls. Conclusion HBO therapy can significantly decrease serum CRP and TNF-α after severe TBI, thus enhancing therapeutic efficacy.

Objective To explore how medical staff in the oncology department understand management of cancer related fatigue (CRF), and explore what factors influencing the effective practice of CRF management. Methods Qualitative inquiry was adopted. Ten medical staffs in the oncology department were selected for in- depth interview. Generic analysis was applied to code, categorize and interpret the qualitative data. Results Participants believed that many factors influenced the CRF, which hadn′t been assessed as an independent symptom and lacked the systematic, effective and specific interventions. The medical staff, patients and their families neglecting the CRF management was the main barrier. Strengthening system construction and staff training was mentioned as major area which needed to be improved. Conclusions CRF management guideline should be formulated according to our national situations based on the clinical practices, besides, the training of correlated clinical knowledge and skills of medical staff should be strengthened and eventually promote the cancer patients′quality of life.

Objective To investigate the effects of hyperbaric oxygen (HBO) therapy on interleukin-1 β( IL-1 β) and interleukin-6 ( IL-6 ) levels in patients with moderate or severe traumatic brain injury ( TBI ) and to analyze its therapeutic efficacy.MethodsOne hundred and fifty-six patients with moderate or severe TBI were randomly divided into a control group and an HBO adjunctive therapy group with 78 cases in each.The control group received essential neurosurgical treatment and conventional drug treatment,and the HBO group was given one HBO therapy session in addition.IL-1 β and IL-6 were quantitatively determined using sandwich ELISA,and the patients'scores on the Glasgow coma scale (GCS) were measured before and after treatment.The Glasgow outcome scale (GOS) was used to evaluate in a follow-up 6 months after injury.ResultsThe average IL-1 β and IL-6 levels of the two groups and their average GCS scores were not significantly different before treatment.After treatment,IL-1 βand IL-6 levels decreased significantly and GCS scores increased significantly in both groups,but there were significant inter-group differences in all three measures.Six months after injury the GOS evaluation indicated that significantly more patients had better outcomes in the HBO group than in the control group. Conclusion Conventional treatment combined with HBO therapy can promote neurofunction recovery in TBI patients.The mechanism may be related to down-regulation of serum IL-1 β and IL-6.

Objective To evaluate the efficacy and safety of Qingpeng ointment for the treatment of localized eczema in children.Methods A multicenter,randomized,open-labeled,tacrolimus 0.03％ ointment-controlled clinical trial was conducted.A total of 442 children with localized eczema were enrolled into this study,and divided into 2 groups to topically apply Qingpeng ointment (Qingpeng group) and tacrolimus 0.03％ ointment (tacrolimus group) respectively twice a day for 2 weeks.The children were followed up before the treatment and 1,2 weeks after the treatment,and the efficacy and safety were evaluated at the same time.Results Clinical data from 426 children were included in the efficacy analysis.At 1,2 weeks after the treatment,there were no significant differences in the response rate between the Qingpeng group and tacrolimus group (1 week after the treatment:78.92％ vs.81.77％,x2 =0.545,P =0.460;2 weeks after the treatment:98.65％ vs.97.54％,x2 =0.721,P =0.396).However,the pruritus scores at 1,2 weeks after the treatment were both significantly lower in the Qingpeng group than in the tacrolimus group (1 week:F =14.001,P =0.000;2 weeks:F =11.252,P =0.001).At 1 week after the treatment,the incidence rate of adverse reactions was significantly lower in the Qingpeng group than in the tacrolimus group (P ＜ 0.05).Mild itching,burning sensation and other local irritant sensations were the most common adverse reactions.Conclusion Qingpeng ointment is safe and effective for the treatment of localized eczema in children with good tolerability.

Objective:To explore the effects of neonatal stimulator of interferon genes (STING) innate immune signaling pathway of HBsAg-positive mothers on non/hypo-response to hepatitis B vaccine (HepB) in their infants.Methods:From November 2019 to June 2022, HBsAg-positive mothers and their infants in the Third People's Hospital of Taiyuan were recruited as the study subjects. The epidemiological and clinical data were collected by questionnaire survey and medical records review. The key molecular proteins of STING innate immune signaling pathway (STING, pIRF3) and immune cells associated with vaccine response (DC, T and B and plasma cells) in neonatal cord blood were detected by flow cytometry. Follow up was conducted for infants for 1-2 months after the full vaccination of HepB. Serum hepatitis B surface antibody (anti-HBs) was detected by chemiluminescence microparticle immunoassay. Unconditional logistic regression model, nomogram and Bayesian network model were used to evaluate the effect of STING innate immune signaling pathway on non/hypo-response to HepB and related factors in infants, and the relationship between various factors.Results:A total of 195 pairs of HBsAg-positive mothers and infants were recruited, the rate of non/hypo-response to HepB in the infants was 12.31% (24/195). High maternal HBV DNA load, low expression of neonatal STING, low expression of pIRF3 and low percentage of plasma cells were risk factors for non/hypo-response to HepB in the infants ( OR=4.70, 3.46, 3.18 and 2.20, all P<0.05). The nomogram constructed by these factors had good predictive efficacy (area under curve=0.81, 95% CI: 0.63-0.83). The results of Bayesian network model showed that the infants with a high maternal HBV DNA load had a higher conditional probability of low STING expression (62.50%) and a higher conditional probability of low pIRF3 expression (58.54%). The conditional probabilities of low expression of DC, T, B and plasma cells were 53.16%, 60.20%, 68.42% and 57.14%, respectively. Conclusion:Maternal HBV DNA might inhibit STING innate immune signaling pathways in infants and immune cells associated with HepB response, resulting in non/hypo-response to HepB in infants of HBsAg-positive mothers.

Background:MicroRNA-9 (miR-9)is involved in the modulation of a variety of physiological process such as organ development and self-renewal and multipotential differentiation of cells. Moreover,its aberrant expression is closely associated with several types of malignant tumors. Aims:To investigate the effect of miR-9 on biological behavior of human gastric cancer cells. Methods:Expression of miR-9 in normal human gastric epithelial cell line GES-1 and human gastric cancer cell line BGC-823 and SGC-7901 was detected by real-time PCR. Then the two gastric cancer cell lines were transiently transfected with miR-9 mimic,miR-9 inhibitor and empty vector,respectively;the efficiency of transfection was assessed by real-time PCR. CCK-8 assay,Transwell assay and wound healing assay were used to examine the cell proliferation and migration capacities. Results:The expression level of miR-9 was significantly higher in gastric cancer cells than in normal gastric epithelial cells (P＜0. 05). Compared with cells transfected with empty vector,overexpression of miR-9 occurred in cells transfected with miR-9 mimic and effectively promoted the proliferation and migration of BGC-823 and SGC-7901 cells (P ＜ 0. 05 ). Conversely,transfection with miR-9 inhibitor significantly suppressed the proliferation and migration of gastric cancer cells (P＜0. 05). Conclusions:Up-regulating miR-9 expression promotes the proliferation and migration of gastric cancer cells,which indicates that miR-9 overexpression may be associated with progression of gastric cancer.

Objective:To discuss the classification and treatment of ureteroileal anastomotic stricture (UAS) after radical cystectomy.Methods:The clinical data of 34 patients with UAS after radical cystectomy in the Department of Urology of Tongji Hospital from January 2017 to January 2022 were reviewed and analyzed. There were 25 males and 9 females. The average age was (66.3±7.7)years, including 2 cases of bilateral hydronephrosis and 32 cases of unilateral hydronephrosis. The average time of UAS was detected (14.7±6.5)months after radical cystectomy. There were 32 patients of unilateral hydronephrosis and 2 patients of bilateral hydronephrosis. Two patients had undergone nephrostomy in an external hospital. Three patients had elevated leukocytes in blood routine. Among them, two patients had fever. First, nephrostomy on the hydronephrosis side and anti-infection treatment were performed. After routine blood tests showed that the white blood cells were normal and antibiotics were stopped for 24 hours without fever, the operation was performed. 34 patients had preoperative hydronephrosis of (2.7±0.6) cm. Of the 34 cases in this group, 5 cases were injected with methylene blue through a preoperative nephrostomy tube, and 29 were injected with methylene blue through the renal pelvis using an 18G puncture needle under ultrasound guidance. Using a ureteroscope to observe in the ileal bladder, methylene blue was seen in 4 cases. Methylene blue was used to guide the search for the stenosis and a super smooth guide wire was inserted. Among them, 3 cases were dilated with a 5 mm ureteral dilation balloon catheter, 1 case was dilated with a F14 ureteral access sheath, and then a F6 single J stent was inserted. Methylene blue was not seen in the ileal conduit in 30 cases, of which 16 cases were treated with a flexible ureteroscope through the nephrostomy to locate the stenosis, incised with a 30 W holmium laser. 9 cases were treated with 5 mm ureteral dilation balloon catheter, and 7 cases were treated with a F14 ureteral access sheath, and then an F6 single J stent was inserted. 14 cases were unable to find the stenosis by antegrade method. According to the operation time and patient's condition, it was decided to perform immediate or second stage dual endoscope surgery. Through the nephrostomy, a flexible ureteroscope was used to enter the stenosis along the super slide guide wire. A rigid ureteroscope was used to observe the stenosis through the ileal conduit, and the stenosis was found. The stenosis was found in 10 cases and incised with a 30 W holmium laser. 8 cases were treated with 5 mm ureteral dilation balloon catheter, and 2 cases were treated with a F14 ureteral access sheath, and then an F6 single J stent was inserted. 4 cases were still unable to accurately locate the stenosis using the dual endoscope surgery(one case was bilateral stenosis, and one side was relieved), and continued indwelling nephrostomy. The definition of successful removal of stricture in this study is that an F6 single J stent can be inserted into the ureter.Results:UAS were classified into four types based on the severity of the intraoperative findings: Type Ⅰ, the narrow ureteral lumen is more than 50% narrower than the normal ureteral lumen, but methylene blue can pass through in strands; Type Ⅱ, needle like stricture of the ureteral lumen, allowing only methylene blue filaments to pass through; Type Ⅲ, membranous atresia of the ureter, with a narrow segment of 1 to 3 mm in length, and methylene blue cannot pass through; Type Ⅳ, long segment stenosis. Of the 34 cases in this group, 4 cases were type Ⅰ, and the stenosis was dredged by retrograde method; 16 cases were type Ⅱ, and the stenotic segments were dredged by antegrade method; 10 cases were type Ⅲ, and the stenosis was dredged by the dual endoscope surgery; Four cases were of type Ⅳ (one case was of bilateral UAS, one side was of type Ⅲ, and the other side was of type Ⅳ, which was classified as type Ⅳ). The stenotic segment could not be solved through the above methods. Among the 34 patients, 30 patients were successfully relieved of anastomotic obstruction, and 1 patient with bilateral obstruction was unilaterally relieved of anastomotic obstruction. In the other 3 cases, because the stenosis segment was too long, 2 cases were changed to nephrostomy, and 1 case was changed to open surgery, with a success rate of 88.2%. UAS was classified into 4 types based on the severity of UAS seen during surgery. No serious complications occurred during and after the operation. During the follow-up of 6-24 months, the imaging evaluation of 4 patients showed that hydronephrosis was aggravated, with an average increase in creatinine of (32.5±10.9)μmol/L, requiring replacement of a single J tube. The imaging evaluation of the remaining 26 patients showed that the postoperative hydronephrosis was 0.9 ± 0.6 cm less than the preoperative hydronephrosis 2.6 ± 0.6 cm, with a statistically significant difference ( P<0.01). The quality of life score at 3 months after surgery was (1.9±0.6), which was significantly improved compared to the preoperative indwelling nephrostomy period (5.2±0.7), with a statistically significant difference ( P<0.01) Conclusions:The treatment of UAS after radical cystectomy with retrograde, antegrade, and dual endoscope surgery has a high success rate, which can help some patients avoid the inconvenience of indwelling external drainage tubes and the risk of open surgery. Choosing an appropriate surgical method can achieve the goal of treating UAS with minimal trauma.

Ulcerative colitis (UC) is a chronic non-specific intestinal inflammatory disease. Whether surgical treatment should be taken is a difficult and focus decision of clinical practice. Studies have shown that severe complications, combined with severe infection, poor laboratory indices, and ineffective medical treatment are the evaluation elements of UC surgery. This article reviewed the advances in study on high risk factors of surgery with UC.
