ROS-responsive curcumin-encapsulated nanoparticles for AKI therapy via promoting lipid degradation in renal tubules.

Lipid accumulation is a factor contributing to the pathogenesis of acute kidney injury (AKI), yet there are currently no approved pharmacotherapies aside from adjuvant therapy. A developed reactive oxygen species (ROS)-responsive drug delivery system (NPSBG@Cur) was developed to deliver the autophagy activator curcumin (Cur) in order to alleviate AKI by activating autophagy and promoting lipid droplet degradation. The nanoparticles were shown to be ROS-responsive in the H2O2 medium and demonstrate ROS-responsive uptake in palmitate (PA)-induced oxidative stress-damaged cells. NPSBG@Cur was found to effectively inhibit lipid accumulation by autophagosome transport in kidney tubular cells. Additionally, in a mouse AKI model, NPSBG@Cur was observed to significantly ameliorate renal damage by activating autophagy flux and improving lipid transport. These results suggest that the ROS-responsive drug delivery system augmented the therapeutic effect of Cur on AKI by improving lipid metabolism through autophagy activation. Therefore, targeting lipid metabolism with NPSBG@Cur may be a promising AKI treatment strategy.

Applied Research of Case-based Learning Teaching in Nephrology Medicine for Professional Postgraduate Students in Clinical Medicine.

Objective: To explore the influence of case-based learning (CBL) teaching methods in comparison to the traditional lecture-based learning (LBL) model in clinical teaching of nephrology for master's degree students in clinical medicine. Methods: Clinical medicine master's degree students who were trained in the Department of Nephrology, The First Affiliated Hospital of Nanjing Medical University from December 2015 to December 2021 were selected as the study objects. The selected students were divided into two groups: the LBL group comprised 16 graduate students who received the traditional LBL model from December 2015 to December 2018, and the CBL group comprised 18 graduate students who received the CBL teaching methods from January 2019 to December 2021. Both groups participated in the professional theoretical knowledge assessment, including objective and subjective questions and calculating the total score), and the examination of clinical skills communication ability, preparation of handling materials, anesthesia techniques, operational skills, aseptic techniques, and postoperative management), at the time of discharge from the department. The independent learning ability (self-management ability, information ability, and learning ability) of students of the two groups after teaching was then assessed, and the satisfaction of the two groups with their respective teaching mode (including satisfaction with the teaching format, teaching effectiveness, interest stimulation, independent learning and the improvement of teamwork ability) was assessed by the questionnaire on the degree of satisfaction of the two groups. Results: The assessment scores of professional theoretical knowledge in the CBL group were significantly higher than those in the LBL group in objective questions, subjective questions, and total scores (P1 = .028; P2 = .036; P3 = .041). The CBL group scored higher than the LBL group in the assessment of communication skills, preparation of operative items, anesthesia technique, operative skills, aseptic technique, and postoperative handling skills, but the differences were not statistically significant (P1 = .071; P2 = .260; P3 = .184; P4 = .127; P5 = .352; P6 = .584). The self-management ability, information ability, and learning ability scores of students in the CBL group were significantly higher than those in the LBL group (P1 = .006; P2 = .013; P3 = .003). Students in the CBL group were significantly higher than those in the LBL group in terms of satisfaction with teaching form, teaching effect, interest stimulation, improvement of independent learning ability, and satisfaction with teamwork ability (P1 = .015; P2 = .008; P3 = .010; P4 = .024; P5 = .022). Conclusions: The CBL teaching model can improve and enhance the clinical thinking ability of clinical medicine master's degree students in nephrology, and stimulate their interest in learning. Professional master's degree students have a high degree of satisfaction with the CBL model.

Effect of Moxibustion Combined With Cisplatin on Tumor Microenvironment Hypoxia and Vascular Normalization in Lewis Lung Cancer Mice.

PURPOSE: This study was developed to evaluate the effects of moxibustion on tumor microenvironmental hypoxia in a murine model of Lewis lung carcinoma (LLC). METHODS: Twenty-four tumor-bearing mice were randomized into tumor group (T), tumor + cisplatin group (TC), tumor + moxibustion group (TM), and tumor + cisplatin + moxibustion group (TMC) (n = 6/group). Six age-matched C57BL/6 mice were employed as control group (Ctrl). A tumor model was established by implanting LLC cells into the right flank of each mouse. Animals in the TM group received moxibustion treatment at the ST36 (bilateral) and GV4 acupoints on the day of visible tumor formation. Moxibustion treatment was performed every other day for a total of 7 sessions. Animals in the TC group were intraperitoneally injected with cisplatin (3 mg/kg) on day 3 after visible tumor formation, and this treatment was performed every 3 days for 4 times. Animals in the TMC group underwent combined moxibustion and chemotherapy treatment, following the same conditions as outlined above. Following treatment, the concentrations of hypoxia-inducible factor-1α (HIF-1α), vascular endothelial growth factor (VEGF), CD31, and Ki67 were measured using ELISA, Western blot, and immunohistochemical staining. RESULTS: Compared to the tumor group, treatment in the TM, TC, and TCM groups resulted in varying reductions in tumor growth (P < .001 or P < .05), while tumor microenvironmental hypoxia was alleviated as evidenced by the downregulation of HIF-1α, VEGFA, and CD31(P < .001-P < .05). CONCLUSION: Our results suggest that a combined approach of moxibustion and cisplatin can alleviate intratumoral hypoxia, promote vascular normalization, and slow the growth of LLC tumors in mice.

Lateral hypothalamic orexin neurons mediate electroacupuncture-induced anxiolytic effects in a rat model of post-traumatic stress disorder.

The lateral hypothalamus' orexinergic system has been associated with anxiety-related behaviors, and electroacupuncture (EA) modifies orexin neurons to control the anti-anxiety process. However, in a rat model of post-traumatic stress disorder (PTSD), the important role of LH orexin neurons (OXNs) in the anxiolytic effects induced by EA has not been explored. In this study, rats underwent modified single prolonged stress (MSPS) for seven days before developing EA. The rats were then subjected to elevated plus maze (EPM) and open field (OFT) tests, and western blot and c-Fos/orexin double labeling investigations were carried out to determine the functional activation of LH orexinergic neurons. Compared to MSPS model rats, it has been demonstrated that EA stimulation enhanced the amount of time spent in the central zone (TSCZ) in OFT and the amount of time spent in the open arm (TSOA) in EPM in MSPS model rats (P < 0.01). After behavioral testing, MSPS model rats had decreased activated c-Fos positive OXNs. Still, EA in SPS rats increased that number and elevated orexin type 1 receptors (OXR1) protein expression in the LH. Furthermore, after administering SB334867 (an OXR1 antagonist) to MSPS model rats, the effects of EA therapy on anxiety-like behaviors (ALBs) were significantly diminished. Additionally, when low-dose orexin-A (LORXA) was administered intracerebroventricularly together with EA stimulation in MSPS rats, the anxiolytic effects of the stimulation were substantially enhanced (P < 0.05). The results of this study reveal the mechanisms by which acupuncture may reduce PTSD and advance our understanding of the function of LH orexin signaling in EA's anxiolytic effects.

The characteristics of registered acupuncture clinical trials enrolling cancer patients.

PURPOSE: This study sought to explore and summarize the global state of acupuncture clinical trials enrolling cancer patients included in international registries to date. METHODS: All relevant trials evaluating acupuncture-related interventions for the treatment of cancer that were registered in 16 trial registries from January 1, 2001, through December 31, 2020, were identified. Subsequent publications related to these trials were additionally retrieved from the PubMed, Cochrane Library, Embase, CNKI (China National Knowledge Infrastructure), VIP (China Science and Technology Journal Database), and Wanfang databases. We compared information included in these registries regarding completed trials with any associated publications, with a focus on study design, sample size, and selective reporting, based on the registered protocol. RESULTS: In total, 222 eligible trials across 19 countries were identified. These trials included 17 specific cancer types and 32 symptoms. The five most common cancer types were breast cancer, head and neck cancer, colorectal cancer, lung cancer, and gastric cancer, accounting for almost half of all registered trials (48.2%). The top five symptoms included in these trials were chemotherapy-induced peripheral neuropathy (CIPN), cancer-related pain, cancer-related fatigue, chemotherapy-induced nausea and vomiting (CINV), and gastrointestinal dysfunction. The overall rate of article publication was low, with publications being associated with just 33.3% of these registered trials. CONCLUSIONS: This review is the first snapshot of the landscape of acupuncture clinical trials registered in international trial registries, providing a methodological basis for the management of common treatment- and disease-related side effects among cancer patients undergoing acupuncture and offering useful information that will guide future acupuncture-focused research.

Exploring the perceptions of the educational environment in online acupuncture learning during the COVID-19 pandemic.

OBJECTIVE: Students have had to adapt to a "new normal" of online education at home during the COVID-19 pandemic. This poses a considerable challenge to the conduct of online acupuncture courses. Here, we provide our experience and guidance for conducting an online experimental acupuncture course during the COVID-19 pandemic. We aimed to compare the different perceptions of undergraduates to the educational environment between online and face-to-face learning approaches. METHODS: This study included senior undergraduates majoring in acupuncture during the academic years 2015 (face-to-face) and 2020 (online only) for the Experimental Acupuncture course. A survey was conducted at the end of this course. The Dundee Ready Educational Environment Measure (DREEM) questionnaire was used to assess students' perceptions. The results of students' responses to online learning were compared with those assessed for face-to-face learning. RESULTS: In total, 56/70 (80%) students in 2015 and 49/54 (91%) students in 2020 completed the questionnaire, respectively. Total DREEM scores were higher in the online learning group than in the face-to-face learning group (160.3 ± 21.9 vs 147.6 ± 17.9, p = 0.007), with improved students' perceptions on four out of five dimensions (social self-perception, learning, atmosphere and academic self-perception). The positive aspects of their online learning experience included the acquisition of new knowledge and skills. The significant limitations of this course included the lack of practical classes. CONCLUSION: Students' perceptions regarding the Experimental Acupuncture program were satisfactory for both online and face-to-face learning approaches, but even better with online learning. Online learning may be encouraged in traditional Chinese medicine (TCM) education. However, a combination of face-to-face and online methods is likely to be required to maximize the benefits. We hope that our online Experimental Acupuncture program practices may assist in the development of online curricula for acupuncture during the COVID-19 pandemic.

Electroacupuncture Attenuates Anxiety-Like Behaviors in a Rat Model of Post-traumatic Stress Disorder: The Role of the Ventromedial Prefrontal Cortex.

Electroacupuncture (EA) is a promising clinical approach to treating posttraumatic stress disorder (PTSD), yet the mechanisms whereby EA can alleviate anxiety and other PTSD symptoms have yet to be clarified. In the present report, rats underwent EA for 14 consecutive days following modified single prolonged stress (MSPS) exposure. These animals were then evaluated in open field and elevated plus maze tests (OFT and EPM), while Fos immunohistochemical staining was performed to assess ventromedial prefrontal cortex (vmPFC) functional activation. In addition, an extracellular recording and stimulation system was used to analyze vmPFC inputs into the ventral tegmental area (VTA) in these rats. Temporary vmPFC inactivation was further performed to assess whether this was sufficient to reverse the anxiolytic effects of EA. Overall, rats that underwent EA treatment spent more time in the central region (OFT) and the open arm (EPM) relative to MSPS model animals (P < 0.05). These MSPS model animals also exhibited significantly fewer activated Fos-positive nuclei in the vmPFC following behavioral testing, while EA was associated with a significant relative increase in c-Fos expression in this region. The transient inactivation of the vmPFC was sufficient to reverse the effects of EA treatment on anxiety-like behaviors in MSPS model rats. MSPS and SEA rats exhibiting no differences in bursting activity between baseline and vmPFC stimulation, whereas bursting activity rose relative to baseline upon ventral mPFC stimulation in EA treated and control rats. Together, these findings indicate that the vmPFC and its inputs into the VTA are functionally linked to the anxiolytic activity of EA, implicating this pathway in the EA-mediated treatment of PTSD.

Effects of 10.6-µm laser moxibustion and electroacupuncture at ST36 in a 5-Fu-induced diarrhea rat model.

OBJECTIVE: The aim of this study was to investigate the effect of 10.6-µm laser moxibustion and electroacupuncture in 5-fluorouracil (5-Fu)-induced diarrhea model rats. METHODS: Forty-eight Sprague Dawley rats were randomly divided into 4 groups: a normal group, model group, 10.6-µm laser moxibustion (LM) group, and electroacupuncture (EA) group. Diarrhea was induced by 5-Fu (50 mg/kg) injection in 36 rats; the LM and EA groups received treatment at acupoint ST36 (Zusanli) on hind limbs once a day for 6 days. RESULTS: 5-Fu injection caused body weight decline and diarrhea. From the 5th to 7th day, the LM group showed higher body weights than the model group (P < 0.05). On the 6th day, diarrhea score of the LM group was better than that of the EA group (P < 0.05). Both scores of the LM group and EA group were better than that of model group (P < 0.05). The LM group and EA group both had better intestine pathological scores and lower endotoxin (ET) and diamine oxide (DAO) activity than the model group (P < 0.01). The LM group got better pathological scores than the EA group (P < 0.01). Ultramicroscopic structures of the model group showed severe damage while the LM group and EA group remained good in their small intestines. The model group had obviously decreased occludin protein in intestine tissues than the control group (P < 0.01), while occludin expressions in the LM group and EA group were both obviously increased compared with the model group (P < 0.01). CONCLUSION: LM and EA treatment on ST36 could alleviate damage to intestinal barrier function and alleviate diarrhea caused by 5-Fu.

Effects of infrared laser moxibustion on cancer-related fatigue in breast cancer survivors: Study protocol for a randomized controlled trial.

BACKGROUND: Cancer-related fatigue (CRF) is the most common and distressing symptom associated with cancer treatment that breast cancer survivors (BCS) experience. We previously found that laser moxibustion may be efficacious for CRF. The primary aim of this study is to determine the specific efficacy of 10.6 µm infrared laser moxibustion on CRF. The secondary aim is to evaluate the effect of infrared laser moxibustion on co-existing symptoms that BCS experience. METHODS: We will conduct a randomized, sham-controlled, three-arm trial of infrared laser moxibustion (ILM) against sham ILM (SILM) and waitlist control (WLC) among BCS with moderate to severe fatigue. The two intervention groups will receive either real or sham infrared laser moxibustion on four acupoints (i.e., ST36 [bilateral], CV4, and CV6) for 20 minutes each session for 6 weeks (twice per week). The primary endpoint is the change in fatigue score from Baseline to Week 6 as measured by the Chinese version of the Brief Fatigue Inventory (BFI-C). Our secondary aim is to compare the severity of co-morbidities (e.g., depression, insomnia, and pain) among the 3 groups. DISCUSSION: The results of our trial will establish evidence for the efficacy of infrared laser moxibustion for CRF, a very common and challenging symptom. TRIAL REGISTRATION NUMBER: NCT03553355.

Bone metabolism markers and hungry bone syndrome after parathyroidectomy in dialysis patients with secondary hyperparathyroidism.

OBJECTIVE: To explore the short-term variation in bone metabolic markers and the characteristics of hungry bone syndrome (HBS) after parathyroidectomy (PTX) with forearm autotransplantation in uremic patients with secondary hyperparathyroidism (SHPT) and to provide a basis for the pathogenesis, diagnosis and treatment of metabolic bone disease in SHPT. METHODS: A total of 115 patients with SHPT receiving PTX from July 2015 to December 2017, hospitalized at the First Affiliated Hospital of Nanjing Medical University, were enrolled in our study. We retrospectively analyzed the baseline clinical data, the levels of bone metabolism markers before and on the third day after PTX, and the risk factors predicting HBS. RESULTS: Preoperative baseline data showed that the levels of bone metabolic markers such as bone metabolism-regulating hormones: iPTH, calcitonin (CT); bone formation markers: phosphatase (ALP), osteocalcin (OC); bone resorption markers: type I collagen cross-linked N-telopeptides (NTX), type I collagen cross-linked C-telopeptides (CTX), tartrate-resistant acid phosphatase 5b (TRAP-5b) were all increased compared to normal levels. The levels of postoperative serum iPTH, CT, CTX and TRAP-5b decreased significantly compared to preoperative levels, while the levels of OC and ALP increased significantly. Of the 115 patients, 101 (87.8%) developed HBS after PTX. High preoperative serum ALP and low preoperative serum calcium level independently predicted the occurrence of HBS. Younger preoperative age, high preoperative serum ALP and iPTH level independently predicted the severity of HBS. CONCLUSIONS: In severe SHPT, both bone formation and resorption were active, which suggested the presence of high-turnover bone diseases characterized by up-regulation of osteoclasts-osteoblasts functionally coupling activation in the patients. PTX could promote osteoblast activity and reduce osteoclast activity. HBS was common after PTX. Preoperative higher serum ALP and lower calcium were independent predictors of the occurrence of HBS. Younger patients with higher preoperative ALP and PTH may need to closely monitor serum calcium levels and intensive calcium supplementation after PTX.

Peritoneal dialysis can alleviate the clinical course of hungry bone syndrome after parathyroidectomy in dialysis patients with secondary hyperparathyroidism.

PURPOSE: It is unclear whether clinical courses of hungry bone syndrome (HBS) after parathyroidectomy (PTX) in peritoneal dialysis (PD) and hemodialysis (HD) patients are different. The present study aimed to investigate the possible differences of postoperative hypocalcemia and hyperkalemia between PD and HD patients. METHODS: We performed retrospectively 29 PD patients as the PD group and 169 HD patients as the HD group undergoing successful total PTX with autotransplantation. Calcium supplement after surgery was recorded. Higher levels of serum potassium during and immediately after surgery were recorded as K+d0. K+d3 was recorded as peak pre-dialysis serum potassium level 3 days post-surgery. RESULTS: There were 157 (92.90%) patients in HD group and 22 (75.86%) patients in PD group suffered from HBS after surgery, with significant difference between the groups (P = 0.004). Patients in PD group had significantly shorter intravenous calcium supplement duration (P = 0.037) and significantly smaller intravenous calcium supplement dosage (P = 0.042) and total calcium supplement dosage during hospitalization (P = 0.012) than patients in HD group. The levels of serum K+d0 (P < 0.001) and K+d3 (P < 0.001) were both significantly lower in PD group than those in HD group. Peritoneal dialysis was one of the independent influencing factors with negative correlation for calcium supplement, serum K+d0 and serum K+d3. CONCLUSIONS: Compared with HD patients, the clinical course of HBS after PTX in PD patients was alleviated. Efforts should be devoted to individual perioperative management for PD patients undergoing PTX.

Effects of Niaoduqing Particles () on Delaying Progression of Renal Dysfunction: A Post-trial, Open-Label, Follow-up Study.

OBJECTIVE: To follow up the participants of the randomized clinical trial "Efficacy and Safety of Niaoduqing Particles () for Delaying Moderate-to-Severe Renal Dysfunction", and assess the long-term effects of Niaoduqing Particles on delaying the progression of renal dysfunction. METHODS: Participants, who had previously been randomly assigned to receive Niaoduqing Particles or placebo for 24 weeks (146 cases in each group), were invited to follow-up and all were administered Niaoduqing Particles 5 g thrice daily and 10 g before bedtime for 24 weeks. The primary endpoints were changes in baseline serum creatinine (Scr) and estimated glomerular filtration rate (eGFR) after completion of the open-label treatment period. RESULTS: After the double-blind period, the median (interquartile range) changes in Scr were 1.1 (-13.0-24.1) and 11.7 (-2.6-42.9) µmol/L for the Niaoduqing Particle and placebo groups, respectively (P=0.008), and the median changes in eGFRs were-0.2 (-4.3-2.7) and-2.21 (-5.7-0.8) mL•min-1•1.73 m-2, respectively (P=0.016). There were significant differences in the double-blind period changes in renal function between groups. After the open-label period, the median changes in Scr were 9.0 (-10.0-41.9) and 17.5 (-6.0-50.0) µmol/L for the Niaoduqing Particle and placebo groups according to baseline grouping, respectively (P=0.214), and the median changes in eGFRs were-2.3 (-6.4-1.9) and-3.7 (-7.5-1.1) mL•min-1•1.73 m-2, respectively (P=0.134). There were no statistical differences in the open-label period changes in renal function between groups. The eGFR reduction of participants who accepted Niaoduqing Particle treatment for 48 weeks was projected to 2.5 mL•min-1•1.73 m-2 per year. CONCLUSION: Niaoduqing Particles appear to have long-term efficacy for patients with moderate-to-severe renal dysfunction. Although there was no statistical difference, the early use of Niaoduqing Paticles seems to ameliorate the worsening of renal function. (Trial registration No. ChiCTR-TRC-12002448).

Hypocalcemia-based prediction of hungry bone syndrome after parathyroidectomy in hemodialysis patients with refractory secondary hyperparathyroidism.

OBJECTIVE: This study was performed to explore the risk factors for hungry bone syndrome (HBS) and establish prediction equations for calcium supplementation after parathyroidectomy in hemodialysis patients with secondary hyperparathyroidism. METHODS: We retrospectively analyzed data from 252 hemodialysis patients undergoing successful total parathyroidectomy with autotransplantation. HBS was defined according to a minimum postoperative serum corrected calcium (PcCa) concentration of <2.0 mmol/L. Independent predictors of HBS were analyzed, and prediction equations for HBS were derived accordingly. Results The incidence of HBS was 71.4%. The serum corrected calcium and preoperative serum alkaline phosphatase (ALP) concentrations were independent predictors of HBS. The preoperative serum ALP, intact parathyroid hormone (iPTH), and hemoglobin concentrations were independent factors influencing the average descending velocity of the PcCa concentration before calcium supplementation (PcCa-V), intravenous calcium supplement holding time (IVCa-T), and intravenous calcium supplement dosage (IVCa), while the serum ALP and iPTH concentrations were independent predictors of the oral calcium supplement dosage (OCa). Four prediction equations for PcCa-V, IVCa-T, IVCa, and OCa were established. CONCLUSIONS: Establishment of prediction equations for HBS may contribute to a new individualized therapy for patients with HBS.

Efficacy and Safety of Niaoduqing Particles for Delaying Moderate-to-severe Renal Dysfunction: A Randomized, Double-blind, Placebo-controlled, Multicenter Clinical Study.

BACKGROUND: Chronic kidney disease (CKD) with moderate-to-severe renal dysfunction usually exhibits an irreversible course, and available treatments for delaying the progression to end-stage renal disease are limited. This study aimed to assess the efficacy and safety of the traditional Chinese medicine, Niaoduqing particles, for delaying renal dysfunction in patients with stage 3b-4 CKD. METHODS: The present study was a prospective, randomized, double-blind, placebo-controlled, multicenter clinical trial. From May 2013 to December 2013, 300 CKD patients with an estimated glomerular filtration rate (eGFR) between 20 and 45 ml·min-1·1.73 m-2, aged 18-70 years were recruited from 22 hospitals in 11 Chinese provinces. Patients were randomized in a 1:1 ratio to either a test group, which was administered Niaoduqing particles 5 g thrice daily and 10 g before bedtime for 24 weeks, or a control group, which was administered a placebo using the same methods. The primary endpoints were changes in baseline serum creatinine (Scr) and eGFR after completion of treatment. The primary endpoints were analyzed using Student's t-test or Wilcoxon's rank-sum test. The present study reported results based on an intention-to-treat (ITT) analysis. RESULTS: A total of 292 participants underwent the ITT analysis. At 24 weeks, the median (interquartile range) change in Scr was 1.1 (-13.0-24.1) and 11.7 (-2.6-42.9) µmol/L for the test and control groups, respectively (Z = 2.642, P = 0.008), and the median change in eGFR was -0.2 (-4.3-2.7) and -2.2 (-5.7-0.8) ml·min-1·1.73 m-2, respectively (Z = -2.408, P = 0.016). There were no significant differences in adverse events between the groups. CONCLUSIONS: Niaoduqing particles safely and effectively delayed CKD progression in patients with stage 3b-4 CKD. This traditional Chinese medicine may be a promising alternative medication for patients with moderate-to-severe renal dysfunction.

Effects of infrared laser moxibustion on cancer-related fatigue: A randomized, double-blind, placebo-controlled trial.

BACKGROUND: Fatigue is the most common symptom negatively affecting the quality of life of patients with cancer. The objective of the current study was to evaluate the preliminary efficacy and safety of 10.6-µm infrared laser moxibustion for cancer-related fatigue (CRF). METHODS: The authors conducted a randomized, placebo-controlled trial among 78 patients with cancer who were diagnosed with CRF. The group treated with infrared laser moxibustion received 10.6 µm of infrared laser moxibustion on the ST36 (bilateral), CV4, and CV6 acupoints. Each participant received a 20-minute treatment session 3 times per week for 4 weeks. The sham group received the same treatment duration on the same acupoints, but without infrared laser output. The outcome was change in fatigue as measured by the Chinese version of the Brief Fatigue Inventory between groups at week 4 with additional evaluation at week 8 for durability of treatment effects. A mixed effects model was used to evaluate the difference in treatment effect over time. RESULTS: Among those randomized, 61 patients (78%) completed the entire study. At the end of the intervention, the individuals in the group treated with the laser were found to have significantly less fatigue than those in the sham group (3.01 vs 4.40; P = .002). The improvement in fatigue persisted to week 8, favoring the group treated with laser moxibustion (3.03 vs 4.26; P = .006). Laser moxibustion was safe, with 3 cases of mild local erythema that resolved without medical intervention reported. CONCLUSIONS: Infrared laser moxibustion appeared to be safe and efficacious for improving CRF in a Chinese patient population. Larger studies in more racial/ethnically diverse populations are needed to confirm the benefit of this technique for fatigue in patients with cancer. Cancer 2016;122:3667-72. © 2016 The Authors.

A novel method HPLC-DAD analysis of the Contentsof Moutan Cortexand Paeoniae Radix Alba with similar constituents-monoterpene glycosides in Guizhi Fuling Wan.

A variety of traditional Chinese medical formulations contain two or more herbs from the same genus or family. Although these herbs may have a similar appearance and constituents, they usually have different pharmacodynamic actions. A series of qualitative and quantitative analysis methods are developed to determine one or more compounds for quality control of medicine. As far as we know, no method has been found to determine the real ratio of the two herbs along with the prescription. In this study, we used HPLC-DAD as a way to determine the content of Moutan cortex (M) and Paeoniae radix alba (P) in GuizhiFuling Wan (GZFLW). An effective, accurate and reliable HPLC-DAD method was developed for detecting the content of M and P in GZFLW through the analysis of four monoterpeneglycosides, namely, galloylpaeoniflorin (1), paeoniflorin (2), mudanpioside C (3) and benzoylpaeoniflorin (4). Due to the different UV characteristics of the compounds, the detection wavelength was 270 nm for 1 and 2, while 3 and 4 were monitored at 254 nm and 230 nm, respectively. Four equations were put forward to describe the relationship between content of M as well as P and the four monoterpene glycosides in GZFLW. After validation, all the accuracies of the M and P contents in GZFLW were within 10%. The result showed that the method could be successfully applied to analyze the contents of M and P in GZFLW. Moreover, our method may be more widely used to control the quality of proprietary Chinese medicines, especially for those containing the same genus or family herbs, in industrial GMP production.

Effects of electroacupuncture on ethanol-induced impairments of spatial learning and memory and Fos expression in the hippocampus in rats.

It is well established that alcohol impairs spatial learning and memory. Here, we investigated the effects of electroacupuncture (EA) at ST36 or nonacupoint on ethanol-induced learning and memory impairment and the expression of Fos in the hippocampus. Ethanol (5g/kg) was administered intragastrically once a day for 5 consecutive days; 2Hz EA was administered immediately after ethanol exposure. After a 2-day ethanol abstinence, for 6 consecutive days, the rats were submitted to Morris water maze training. Probe trials were performed on 1 day after the final training session. We also applied immunohistochemistry to detect Fos-positive nuclei in the hippocampus. We found that 5-day ethanol exposure markedly decreased spatial learning and memory abilities in the Morris water maze task as indicated by escape latency and time in the target quadrant. EA treatment shortened the time of reaching platform and increased times traveled in the target quadrant (P<0.05). Animals administered with ethanol emitted significantly fewer Fos expression in the hippocampal CA1 area. EA increased Fos expression in the hippocampal CA1 area. Significant correlations were obtained between Fos protein expression in CA1 and time in the target quadrant. Altogether, these results suggest that EA protects against ethanol-induced impairments of spatial learning and memory, which may be involved in the hippocampal CA1 area. EA treatment may provide a novel nonpharmacological strategy for ethanol-induced learning and memory impairment.

The effect of electroacupuncture on extinction responding of heroin-seeking behavior and FosB expression in the nucleus accumbens core.

Augmentation of extinction with learning enhancing therapy may offer an effective strategy to combat heroin relapse. Our lab previously found that electroacupuncture (EA) not only significantly reduced cue-induced reinstatement of heroin seeking but also exhibited a promoting effect on the ability of learning and memory. In the present study, we further investigated the effects of EA on the extinction of heroin-seeking behavior in rats with a history of intravenous heroin self-administration. We trained Sprague-Dawley rats to nose-poke for i.v. heroin either daily for 4h or 25 infusions for 14 consecutive days; then the rats underwent 7 daily 3h extinction sessions in the operant chamber. To assess EA's effects on the extinction response of heroin-associated cues, 2Hz EA was administered 1h before each of the 7 extinction sessions. We also applied immunohistochemistry to detect FosB-positive nuclei in the nucleus accumbens core. We found that EA treatment facilitated the extinction response of heroin seeking but did not alter the locomotor activity in an open field testing environment. EA stimulation attenuated the FosB expression in the core of the nucleus accumbens, a brain region involved in the learning and execution of motor responses. Altogether, these results suggest that EA may provide a novel nonpharmacological approach to enhance extinction learning when combined with extinction therapy for the treatment of heroin addiction.

[Treatment of chronic primary glomerulopathy patients of Shen deficiency and dampness heat syndrome by yishen qingli granule combined low-dose Tripterygium wilfordii multiglycoside tablet: a clinical efficacy observation].

OBJECTIVE: To evaluate the clinical efficacy and safety of treatment of chronic primary glomerulopathy (CPG) patients of Shen deficiency and dampness heat syndrome (SDDHS) by Yishen Qingli Granule (YQG) combined with low-dose Tripterygium Wilfordii multiglycoside Tablet (TWT). METHODS: Totally 231 CPG patients of SDDHS were enrolled in this study (including 60 patients from First Affiliated Hospital of Nanjing University of Chinese Medicine, 58 from First Affiliated Hospital of Nanjing Medical University, 46 from Xinqiao Hospital of Third Military Medical University, 35 from First Affiliated Hospital of Guangzhou University of Chinese Medicine, 14 from First Affiliated Hospital of Soochow University, and 18 from Wuxi Affiliated Hospital of Nanjing University of Chinese Medicine). They were randomly assigned to the control group (116 cases) and the trial group (115 cases) according to block group method. There were 217 cases in the safety analysis set (109 cases in the trial group vs 108 cases in the control group), and 203 cases in the full analysis set (99 cases in the trial group vs 104 cases in the control group). All patients received basic treatment such as ACEI/ARB. Furthermore, YQG (consisting of raw astragalus 10 g, prepared Polygonum Multiflorum 10 g, Pyrrosia 10 g, 1.5 g each package, containing 10 g of crude drugs) was additionally given to patients in the trial group, each package, twice daily. The TWT (10 mg) was given, twice a day. The TWT dose was adjusted according to 24 h urinary total protein (UTP). The placebos of YQG and TWT were administered to those in the control group. The treatment course consisted of 24 weeks and the follow-up visit lasted for 24 weeks. The biochemical indices were observed before and after treatment including 24 h UTP, urine red cell count (U(RBC)), renal functions (BUN, SCr), blood routine test (WBC), and liver functions (SGPT, SGOT). Reverse reactions such as gastrointestinal discomfort, skin rash, and irregular menstruation were also observed. RESULTS: Compared with the control group, the total effective rate was better in the trial group (82.83% vs 61.54%, P < 0.01). Results of stratified comparison of UTP showed better efficacy in the trial group (0.8-3.0 g/24 h, P < 0.01). The UTP decline occurred in the trial group after 8 weeks of treatment, with stable action, showing statistical difference when compared with the control group (P < 0.01). In the trial group, U(RBC) level decreased after treatment but changed more significantly. But there was no statistical difference in the changes when compared with the control group (P > 0.05). After treatment, there were no statistical difference in safety indicators such as WBC, SGPT, and SGOT between the two groups after treatment (P > 0.05). CONCLUSION: On the basis of basic treatment such as ACEI/ARB, application of YQG combined with low-dose TWT had better effect in controlling proteinuria of CPG patients, and could help stabilizing their conditions with less adverse reactions.
