Objective:To explore risk factors of skin pruritus in peritoneal dialysis patients and the effect of individualized care intervention, to provide guidance for clinical practice.Methods:The total of 87 patients with peritoneal dialysis who were followed-up with pruritus in the Beijing Anzhen Hospital from January 2017 to June 2020 were selected. The Visual Analogue Scale (VAS) was used to evaluate the degree of pruritus, and the patients were divided into two groups: mild-to-moderate skin pruritus group (VAS≤6 points) and severe skin pruritus group (VAS>6 points). The risk factors of severe skin pruritus were analyzed by single factor and multivariate Logistic regression. The improvement of skin pruritus after 3 months of individualized nursing intervention was observed.Results:Among the 87 patients, the mild-to-moderate skin pruritus group and the severe skin pruritus group accounted for 64.4%(56/87) and 35.6%(31/87), respectively. Single factor analysis showed that the age, prevalence of diabetes, serum albumin, serum phosphorus, intact parathyroid hormone and C-reactive protein levels were (61.8 ± 11.5) years old, 33.3%(19/56), (36.3 ± 5.3) g/L, (1.6 ± 0.5) mmol/L, 328.4(144.9, 494.5) ng/L, 2.8(0.6, 8.3) ng/L in the mild-to-moderate skin pruritus group, and (67.0 ± 9.2) years old, 61.1%(19/31), (33.9 ± 4.8) g/L, (1.9 ± 0.3) mmol/L, 397.0(300.0,758.6) ng/L, 7.2(2.6, 17.2) mg/L in the severe skin pruritus group, the differences were significant between the two groups ( t values were -2.17, 2.14, -2.32, Z values were -2.28, -2.90, χ 2 value was 6.07, P<0.05). Logistic multivariate regression analysis showed that low albumin, high blood phosphorus and high C-reactive protein were independent risk factors for severe skin pruritus in peritoneal dialysis patients ( P<0.05). After 3 months of individualized care,18.4% (16/87) patients had complete remission,19.5% (17/87) patients significantly relieved, 55.2% (48/87) relieved, 6.9% (6/87) were ineffective, and the total response rate was 93.1%(81/87). Conclusions:More than one-third of peritoneal dialysis patients with pruritus are severe. Lower serum albumin, higher serum phosphorus and higher C-reactive protein are independent risk factors for severe pruritus in peritoneal dialysis patients. Individualized care can effectively improve pruritus in peritoneal dialysis patients.

OBJECTIVETo analyze and evaluate the clinical efficacy of heat-sensitive moxibustion for symptoms of large intestine cancer.

METHODSSixty patients with large intestine cancer were randomly divided into an observation group and a control group, 30 cases in each one. FOLFOX chemotherapy regimen was used in the two groups,and heat-sensitive moxibustion was added in the observation group. The acupoints were Zusanli(ST 36), Sanyinjiao (SP 6) Xuehai (SP 10) and Geshu (BL 17), etc. The treatment was applied once a day,five-day treatment as one course. Four courses were required. The reaction rates of uncomfortable symptoms by the Chinese version of the M. D. Anderson symptom inventory (MDASI-C) scale and clinical effects were analyzed and evaluated in the two groups.

RESULTSAfter treatment, the MDASI-C reaction rate of uncomfortable symptoms in the observation group was 50.4% which was lower than 53.3% in the control group (P < 0.05). The total effective rate of symptom improvement in the observation group was 83.3% (25/30), which was higher than 60.0% (18/30) in the control group (P < 0.05).

CONCLUSIONHeat-sensitive moxibustion can improve symptoms of chemotherapy for large intestine cancer.

Objective: To compare moxibustion sensation and infrared thermography by the assessment of heat-sensitization on Guanyuan (CV 4) in patients with primary dysmenorrhea, and to prove the possibility of adopting infrared thermography as an objective demonstration of acupoints heat-sensitization. Methods: Seventy-one patients with primary dysmenorrhea were enrolled to receive moxibustion and infrared to detect the heat-sensitization of Guanyuan (CV 4). The results were then analyzed and compared. Results: The infrared radiation showed a lower temperature when the acupoint Guanyuan (CV 4) was sensitized in patients with primary dysmenorrhea. Compared with moxibustion sensation, its sensitivity rate (real positive rate) was 76.6%, divergence rate (real negative rate) was 70.1%, and the accuracy rate was 74.6%. After giving moxibustion to Guanyuan (CV 4), the infrared radiation area was significantly expanded longitudinally and transversely. Compared with moxibustion test, the sensitivity rate (real positive rate) of infrared test was 78.7%, divergence rate (real negative rate) was 83.3%, and the accuracy rate was 80.3%. Conclusion: To a certain extent, the heat-sensitization of the acupoint Guanyuan (CV 4) in patients with primary dysmenorrhea can be revealed by infrared thermography. The acupoint heat-sensitization phenomena (heat extension or transmission) after giving moxibustion to the heat-sensitized acupoints can also be demonstratedobjectively by infrared thermography, besides experienced subjectively by the receivers.

Objective To assess metabolic state in patients with Roux-y sigmoid neobladder.Methods The study comprised 33 patients(21 men and 12 women) with Roux-y sigmoid neobladder after oneological sur-gery.All enrolled patients were treated by the same protocol.Before and after withdrawing the catheter , serum e-lectrolytes, ereatinine and urea were analysed and used to assess the effect.Results All 33 patients were evalu-able.Before and after withdrawing the catheter , serum electrolytes, creatinine and urea were normal values and there was no signifcant difference(P >0.05).Three patients developed mild metabolic acidosis.Conclusions The Roux-y sigmoid neobladder is a feasible , safe and effective method for continent urinary diversion.This surgi-cal technique had no signifcant effect on metabolic state.

BACKGROUND:Several reports have demonstrated that metabolic disorders and physiopathologic changes accompany with urinary diversion.But these metabolic disorders caused by bladder reconstruction using intestinal tract are related to type and length of intestinal canal.OBJECTIVE:To investigate the histological change of reservoir mucosa and to assess effects on metabolic state in patients with a Roux-y sigmoid neobladder.DESIGN,TIME AND SETTING:A retrospective case analysis was performed at the Department of Urinary Surgery,the 184 Hospital of Chinese PLA between June 2000 and November 2008.PARTICIPANTS:The experimental group comprised 33 bladder carcinoma patients,21 males and 12 females,averaging 64 years of age.The control group consisted of 25 subjects who had no sigmoid colon diseases confirmed by gastroenterological endoscopy.METHODS:Patients with bladder carcinoma received radical cystectomy and bladder reconstruction using Roux-y sigmoid neobladder which controlled urination with anal sphincter.Prior to and after neobladder drainage tube removal,serum levels of electrolyte,creatinine,and urea nitrogen were detected.Before and 36 months after surgery,reservoir mucosa from 13 patients with bladder carcinoma was pathologically examined.For the control group,the thickness of sigmoid colon mucosa and the numbers of intestinal glands were determined.MAIN OUTCOME MEASURES:Electrolyte,renal function,acid-base balance,mucosal layer thickness,numbers of intestinal glands prior to and after surgery,as well as prior to and after drainage tube extraction.RESULTS:After surgery,electrolyte,creatinine,and urea nitrogen were all normal in 30 patients.There was no significant difference in serum electrolyte,creatinine,and urea nitrogen between prior to and after surgery.Mild acid poisoning was found in 3 patients.Microscopic observation results revealed that sigmoid colon mucosa in the control group did not change significantly after surgery,and it basically kept the normal tissue structure;in the experimental group,sigmoid colon mucosa that was(577.6±169.4)μm prior to surgery was thinned(412.5±114.7)μm(P＜0.05),intestinal glands were loosely arranged,interstitial substance became less,and the number of intestinal glands per high-fold visual field that was(26.4±3.5)/high-fold visual field prior to surgery was decreased(15.2±2.7)/high-fold visual field(P＜0.05),after surgery.In addition,intestinal villus in the neobladder was gradually atrophied,and no enterocyte proliferation and malignant changes were found after surgery.CONCLUSION:After Roux-y sigmoid neobladder application,colon mucosa was gradually thinned,intestinal glands were loosely arranged,interstitial substance became less,the number of glands per high-fold visual field was decreased,and body metabolism produced no changes.

Objective:To explore the characteristic of dynamic function network connectivity (dFNC) of resting brain networks in internet gaming disorder (IGD) adolescents.Methods:Forty-four adolescent IGD subjects (IGD group, male/female: 38/6) and fifty healthy controls (HC group, male/female: 40/10) were collected, and the subjects completed demographic questionnaires, Young internet addiction scale(YIAS), Chinese adolescents' maladaptive cognitions scale(CAMAS), and functional magnetic resonance imaging (fMRI) tests. The fMRI data were preprocessed on the Matlab platform, and the preprocessed data was divided into 64 components for group level independent component analysis.The dynamic functional connectivity of obtained 18 effective independent components was analyzed by sliding time window technique, and the difference of dynamic functional connectivity of brain triple network between the IGD group and HC group was compared using SPSS 22.0 software.Results:Four repeated dFNC states were identified through cluster analysis.Each state indicated that different functional networks had different connection strengths.State 3, the most frequent state, had been indicated that the whole brain network of the subject was in a state of weak functional connectivity.The second frequent state was state 1, which indicated enhanced functional connectivity within the subject's central executive network (CEN).State 2 had been indicated enhanced functional connectivity within the subject's salience network (SN).State 4 had been indicated generally enhanced functional connectivity in the subjects' brain networks, and this state was the least frequent.The results of non-parametric permutation test on the time attribute showed that compared with the HC group, the IGD group had a longer time score (IGD group: 0.24±0.19, HC group: 0.13±0.15, t=1.19, P<0.05, non-parametric substitution test) for state 1 with strong connectivity within the CEN, which was positively correlated with the YIAS score and game time ( r=0.418, P=0.003; r=0.515, P=0.004).Compared with HC group, the functional connectivity of ICD group between the internal insula of the SN and the dorsal anterior cingulate cortex was enhanced ( P<0.05, FDR corrected), while the average residence time in weakly connected state 3 was longer ( Z=2.09, P<0.05, nonparametric substitution test). Conclusions:The difference in dynamic functional connectivity of the triple network in the brain of IGD adolescents under resting state is mainly manifested by strong connections in CEN, functional connections between insula and dorsal anterior cingulate cortex in SN is enhanced, and weakening of overall functional connections, which may play an important role in the pathological mechanism of IGD.

Objective To evaluate the use of unilateral pedicle lymphography (PLG) in preoperative localization and treatment of chyluria.Methods From October 2010 to March 2017,25 cases with severe chyluria and undergoing cystoscopy and unilateral PLG before renal pedicle lymphatic disconnection were reviewed.There were 11 males and 14 females,aged 44-71 years,with an average of 58.5 years.The course of the disease was 6 months to 30 years,with an average of 8.3 years.Of them,18 cases had undergone unilateral PLG and spiral CT angiography preoperatively.Surgical treatment was performed according to PLG imaging.Results Unilateral ureteral chyluria was discovered in 16 out of the 19 cases through cystoscopy,with the sensitivity of 84.2％ (16/19).In contrast,unilateral chyluria was only detected in 4 of the other 6 patients with bilateral chyluria.Albiduria were found in the remaining 5 cases in bladder,without ureteral excreted chyle.The sensitivity for chyluria positioning by cystoscopy was 64.5％ (20/31).The location of lesion in 19 patients with unilateral chyuria and 6 patients with bilateral chyluria could be correctly displayed by PLG and the sensitivity was 100％ (31/31).There was no significant difference in location between cystoscopy and PLG in 19 patients with unilateral chyluria (P =0.2482).But in total lesion location,the sensitivity of PLG was higher than cystoscopy(P =0.0026).Eighteen patients who had undergone PLG combined with spiral CT angiography,could not only locate the chylous fistula,but also determine the number of renal vessels as well as their relationship with diseased lymphatic vessels.Chyluria had disappeared immediately after unilateral renal pedicle lymphatic exfoliation in 23 patients.However,it still presented in the other 2 patients who were confirmed contralateral pyeloymphatic fistulas by PLG 3 months after surgery and cured by reoperation.Chyluria recurred in 6 cases during follow-up of 6 to 58 months,and 4 were confirmed bilateral pyelolymphatic fistulas by PLG.Two of these 4 cases were cured by laparoscopic surgery or open surgery,respectively.The other 2 patients were cured by conservative treatment.Moreover,2 patients with unilateral chyluria recurred in situ after the first laparoscopic surgery,which was confirmed by PLG.Notably,all these patients were cured by ESWL finally.Conclusions This study suggested that PLG displays remarkable advantage in terms of localization sensitivity.PLG combined with spiral CT angiography preoperatively can not only locate the chylous fistula,but also determine the number of renal vessels as well as their relationship with diseased lymphatic vessels.Depending on PLG and spiral CT angiography,renal pedicle lymphatic disconnection can effectively protect renal vessel.In addition,it can avoid the omission of ligation for perivascular lymphatic vessels.Furthermore,PLG plays a key role in temporarily obstructing the leakage of pyelolymphatic fistulas to some extent.

Parkinson's disease(PD)is the second most common neurodegenerative disease in the world;however,it lacks effective and safe treatments.Ginkgo biloba dropping pill(GBDP),a unique Chinese G.biloba leaf extract preparation,exhibits antioxidant and neuroprotective effects and has a potential as an alternative therapy for PD.Thus,the aims of this study were to evaluate the effects of GBDP in in vitro and in vivo PD models and to compare the chemical constituents and pharmacological activities of GBDP and the G.biloba extract EGb 761.Using liquid chromatography tandem-mass spectrometry,46 GBDP constitu-ents were identified.Principal component analysis identified differences in the chemical profiles of GBDP and EGb 761.A quantitative analysis of 12 constituents showed that GBDP had higher levels of several flavonoids and terpene trilactones than EGb 761,whereas EGb 761 had higher levels of organic acids.Moreover,we found that GBDP prevented 6-hydroxydopamine-induced dopaminergic neuron loss in zebrafish and improved cognitive impairment and neuronal damage in methyl-4-phenyl-1,2,3,6-tetrahydropyridine-induced PD mice.Although similar effects were observed after EGb 761 treatment,the neuroprotective effects were greater after GBDP treatment on several endpoints.In addition,in vitro results suggested that the Akt/GSK3β pathway may be involved in the neuroprotective effects of GBDP.These findings demonstrated that GBDP have potential neuroprotective effects in the treatment of PD.
