Programmed cell death (PCD) is a genetically determined, active and orderly cell death in the organism, and it affects the evolution of the organism, maintenance of its homeostasis, and development of several tissues and organs. The abnormal regulation of this process is closely related to various human diseases, including cancer. The identified pathways of PCD include apoptosis, autophagy, necroptosis, pyroptosis, and ferroptosis, which can be activated when cells are stimulated by various internal and external environmental factors. These pathways can induce cell death or maintain cell survival in kidney cancer cells under the regulation of various signaling molecules, thus affecting tumor progression or therapeutic efficacy. In this paper, the role of these PCD pathways in the development of kidney cancer was reviewed in light of recent research advances to provide new directions for the in-depth study of the pathogenesis of kidney cancer and the development of targeted antitumor drugs.

Objective:To evaluate the reporting quality of diagnostic radiological imaging case reports published in Chinese science citation database (CSCD) imaging journals.Methods:This study was a cross-sectional survey. We searched CSCD to include imaging journals from 2021 to 2022, from which we retrieved diagnostic radiological imaging case reports published in 2020, and evaluated their reporting quality using case reports (CARE) reporting criteria.Results:A total of five imaging CSCD journals were searched, with 161 final diagnostic imaging case reports included. The median and interquartile range reporting rate of the included studies was 33.5% (7.5%, 93.3%), and patient perspective and informed consent were not reported in all studies. Items with reporting rates below 10% included 3a (abstract-introduction), 3c (abstract-diagnoses, therapeutic interventions, and outcomes), 8b (diagnostic challenges), and 8d (prognosis where applicable), with reporting rates of 2.5% (4/161), 0.6% (1/161), 0.6% (1/161), and 4.3% (7/161), respectively. Reporting rates for items between 10% and 50% included 3b (abstract-main symptoms and/or important clinical findings), 4 (introduction), 5c (medical, family, and psycho-social history), 7 (timeline), 10 (follow-up and outcomes), and 11a (a scientific discussion of the strengths and limitations), with reporting rates of 16.8% (27/161), 30.4% (49/161), 34.2% (55/161), 24.8% (40/161), 32.9% (53/161), and 31.7% (51/161), respectively; The reporting rates for item 1 (title), item 2 (keywords), item 5a (identified patient specific information), item 5b (primary concerns and symptoms of the patient), item 8a (diagnostic testing), and item 11c (the scientific rationale for any conclusions) were all over 90%. Moreover, the number of authors as well as the number of disciplines were not associated with the quality of diagnostic imaging case reports.Conclusions:The overall adherence to CARE items in radiographic diagnostic case reports published in the CSCD imaging journals is low. Editors of the imaging journals, radiologists and the researchers of the reporting standard should emphasize the guidelines for drafting case reports and improve the quality of reporting of case reports.

Objective To investigate the effect of the endoscopic surveillance system in irrigating fluid absorption and bleeding during transurethral resection of the prostate.Methods In vitro trials,we simulated the fluid absorption and bleeding in the operation by using self-developed endoscopic surveillance system from January 2013 to June 2013.Continuous irrigation of 5 ％ mannitol solution,we extracted 5 times irrigating fluid (each time 100 ml and a total of 500 ml) in the process of irrigation and recorded absorption measurements of every time extraction rinses.At the same time,we dripped human whole blood 5 times(each time 5 ml and a total of 25 ml) in the process of irrigation and recorded the bleeding measurements.The above process was repeated three times to detect the accuracy and consistency of the endoscopic surveillance system.In clinical trials,50 cases of BPH were monitored in surgery and the biochemical index,hemodynamics,irrigating fluid absorption and bleeding were compared from October 2016 to April 2017.The included criteria contained as follow:the age of patients should be more than 50 years.The transabdominal ultrasound showed that the volume of prostate should be more than 60 ml.The maximal uroflowmetry should be less than 15ml/s.The IPSS scores should be more than 8.Based on the operative time,two groups (＜60 min and ≥ 60 min) were classified.Results We developed the endoscopic surveillance system which is original in the world.In vitro trials,the average irrigating fluid were (100.60 ± 2.07) ml,(201.00±3.39) ml,(302.00±4.67) ml,(403.60±4.39) ml and (502.40 ±7.57) ml;and the average bleeding were (5.06 ± 0.11) ml,(10.10 ± 0.16) ml,(15.04 ± 0.15) ml,(20.06 ± 0.11) ml and (25.10 ± 0.16) ml.No significant difference was observed in all groups (P ＞ 0.05).In clinical trials,we compared some preoperative and postoperative indexes.The average blood oxygen saturation were (94.46 ± 2.49) ％ and (92.39 ± 2.77) ％ (P ＜ 0.01),the average Serum sodium ion concentration were (141.05 ± 2.52) mmol/L and (138.06 ± 4.27) mmol/L(P ＜ 0.01),the average HGB were (143.50 ± 13.43) g/L and (137.04 ± 14.25) g/L(P ＜ 0.01).The average HCT were (42.05 ± 4.09) ％ and (137.04 ± 14.25) ％ (P ＜ 0.01).The average HR were (77.9 ± 7.6) beats per minute and (77.93 ± 6.93) beats per minute (P＞0.05).The MAP were (90.32 ± 9.75) mmHg and (91.07±8.96)mmHg(P＞0.05).The average serum potassium ion concentration were (4.13 ± 0.53) mmol/L and (4.09 ± 0.37) mmol/L (P ＞ 0.05).The average irrigating fluid absorption of the group less than 60 minutes and the group equal or more than 60 minutes were (401.83 ± 279.23) ml and (885.25 ± 367.68) ml (P ＜ 0.01).The average blood loss were (64.10 ±47.47) ml and (158.40 ± 65.22) ml(P ＜0.01).The preoperative and postoperative hemodynamic,blood biochemical and hematology showed difference in our trials.Irrigating fluid absorption and blood loss were positively associated with operation time.Conclusions The endoscopic surveillance system was safety and accuracy.It can offer real-time monitoring data and alarm mechanism for the surgeons that possibly improve operation safety.

Objective To evaluate the effects of remifentanil (RMF)on large conductance cal-cium-activated potassium channel (BKCa)and voltage-gated potassium channel (KV)activition currents in basilar arterial smooth muscle cells (BASMCs)of normotensive and hypertensive rats. Methods Spontaneously hypertensive rats (SHR)and homologous normotensive wistar-kyoto (WKY)rats,were used in this study.BASMCs were obtained freshly by the method of enzymolysis. Six basilar artery smooth muscle cells of each rat were chosen and analyzed.Outward current ampli-tude was recorded by the whole-cell patch clamp technique.The outward current amplitude under all stimulation voltage in set of step stimulation protocol before (basal level)and after administration of RMF (3×10-7mol/L)were recorded respectively and net current was calculated (net current=cur-rent amplitude after administration-basic value).With administration by concentrations cumulative method,the current amplitude under +60 mV stimulation voltage was separately recorded before (basic value)and after application of different concentrations of RMF (10-10,10-9,10-8,10-7, 10-6,10-5mol/L),then calculated current increasing rate and the half effective concentration (EC50)of RMF increasing current amplitude in BASMCs.Another six basilar artery smooth muscle cells of each rat were chosen and given RMF (3×10-7mol/L),and separately treated with BKCa channel blocker (tetraethylammonium,TEA)and Kv channel blocker (4-aminopyridine,4-AP),and then administrated the corresponding RMF mixture.The current amplitude was recorded after each dose.Results At 0,+20,+40 and +60 mV,the net current generated by RMF on both BASMCs of rats was successively and significantly increased (P <0.05).The increment rate of outward currents in BASMCs generated by 10-10,10-9,10-8,10-7RMF successively and significantly went upward (P<0.05).Compared to WKY rats,the half-effective concentration(EC50)of RMF increas-ing the current amplitude in BASMCs of SHR significantly rose(P<0.05).Compared with the base-line,the current amplitude in BASMCs of the two kind rats was significantly increased after adminis-tration of RMF,and decreased after administration of TEA or 4-AP (P<0.05);Compared to ad-ministration of TEA or 4-AP,the current amplitude in BASMCs of the two kind rats was significantly in-creased after administration of TEA+RMF or 4-AP+RMF (P<0.05).Conclusion Bkcaand Kv currents in both BASMCs of SHR and WKY rats were activated by RMF in a voltage-dependent and dose-dependent manner,and the effect of RMF on BKCaand Kvactivition currents in BASMCs of SHR was weaker than WKY rats.

Objective The aim of this study was to investigate and analyze the etiology, seizure type and anti-epileptic drugs (AEDs) utilization of in-patients with epilepsy Methods The study included 5563 cases in-patients with epilepsy. The etiology and seizure type and the date of type, quantity of AEDs in-patient department were collected and their usage frequency were analyzed statistically. Results The most common etiology of epilepsy was traumatic brain injury(13.64%), followed by hippocampal sclerosis (11.52%), stroke (5.24%), nervous system infection (4.98%), perinatal injury ( 5 . 28 % ) and undefined etiology ( 40 . 80 % ) . The most common seizure type was partial seizures (45.43% ). The AEDs of carbamazepine and valproate were the most common used drugs in the clinical and their average usage frequency were 36.88% and 30.80%, respectively. The newer AEDs of Lamotrigine and Levetiracetam were used more frequently. The use of Lamotrigine increased from 16.16% to 28.44% and the Levetiracetam from 0.61% to 20.87% whereas the use of Oxcarbazepine and Topiramate remained a stable level of 15.07% and 9.42%. Conclusion The etiology of epilepsy is complicated and the seizure type of epilepsy was diverse. Among a great variety of anti-epileptic drugs, the newanti-epileptic drugs are being increasingly used.

Purpose To quantitatively evaluate the severity of brain damage in the acute phase of CO poisoning using intravoxel incoherent motion imaging.Materials and Methods MRI scans were performed in 26 patients with CO intoxication of acute stage and 18 healthy controls with matched age and gender.The difference of D value,D* value and f value in different ROIs between the poisoning and the control groups were compared,and the best cut-off values were determined.The correlation between the consciousness state and the D value as well as f value in the vulnerable area of the brain (globus pallidus) was analyzed.Results Compared with control group,the D and F value of the poisoning group were decreased in multiple ROIs,of which statistical significance was observed in the f values in the centrum semiovale,globus pallidus and thalamus,and the D values in the centrum semiovale,lateral ventricle,globus pallidus and corpus callosum splenium (P＜0.05).The best cut-off value,sensitivity and specificity were as follows:fcs=51％,77％,73％;fga=61％,77％,83％;ft=80％,85％,64％;D,=0.69×10-3 mm2/s,85％,83％;Dlv=0.65× 10-3 mm2/s,73％,89％;Dga=0.68× 10-3 mm2/s,62％,83％;Dccs=0.70× 10-3mm2/s,81％,89％.The disturbance of consciousness was positively correlated with decrease of D value and f value (rD=0.828,rf=0.745,P＜0.05).Conclusion The D and f values of intravoxel incoherent motion imaging can quantitatively evaluate the brain damage severity in acute CO poisoning.

Objective To evaluate the efficacy of wax therapy for diabetic peripheral neuropathy, in order to provide suggestions for treatment and prevention.Methods Cochrane Library, JBI, PubMed, EMbase, CBM, CNKI, WANFANG DATA, VIP were searched by computer from inception to October, 2016 for randomized control trails in wax therapy for diabetic peripheral neuropathy. Two researchers searched and selected articles independently and the quality was assessed in accordance with Cochrane Manual. The articles were analyzed with Review Manager 5.3, and the evidence quality was assessed with GRADE profiler 3.6.1 software.Results A total of 8 randomized controlled trials were included. The number of literature quality grade A of original research is 3, while the number of literature quality grade B of original research is 4,and the number of literature quality grade C of original research is 1. Meta-analysis showed that the sensory nervus peronaeus conduction velocities improved by wax therapy for diabetic peripheral neuropathy patients,[MD=2.51, 95%CI(1.35,3.66), P<0.01]. By the GRADE system grading, the evidence quality is moderate.Conclusions The effect of wax therapy for diabetic peripheral neuropathy can improve the sensory nurve conduction velocities and speed of blood circle, so as to prevent ulcer of diabetic feet. Therefore, the clinical curative effects of the therapy require large-sample and high quality studies to confirm.
