Abstract
OBJECTIVE To investigate the immediate effects of electro-acupuncture (EA) on endometrial blood flow among recurrent implantation failure (RIF) patients. METHODS Eighty RIF patients, enrolled from March 2022 to December 2022, were randomly allocated into either the EA group (40 cases) or the waiting-list (WL) group (40 cases) by using a random number table. The EA group underwent acupuncture at points of Shenting (GV 24), Baihui (GV 4), Benshen (GB 13), bilateral Zigong (EX-CA 1), Huangshu (KI 16), Sanyinjiao (SP 6) and Xuehai (SP10), and electric acupuncture apparatus was connected to EX-CA 1, KI 16, SP 6, and SP 10 with disperse-dense waves at 4/20 Hz frequencies for 30 min after transvaginal ultrasound, while the WL group received no intervention. The primary outcome measured was the endometrial volume blood flow. The secondary outcomes included the bilateral uterine artery index, endometrial volume, endometrial blood flow type, vascular distribution index (VIMV) for endometrial and ovary, clinical pregnancy rate, and embryo implantation rate. RESULTS In the EA group, there was a notable decrease in the bilateral pulsatility index and a significant improvement in the endometrial blood flow type post-EA (P<0.05). Both the endometrial blood flow type and VIMV for the endometrium and right ovary were markedly higher in the EA group compared to the WL group post-treatment (P<0.05). Conversely, no significant disparities were observed in vascular index, flow index, vascular blood flow index, uterine arterial blood flow indices, endometrial volume, clinical pregnancy rate and embryo implantation rate between the two groups after treatment (P>0.05). Besides, no adverse events related to EA were observed. CONCLUSIONS EA can promptly ameliorate VIMV for the endometrial and right ovary, and endometrial blood flow type. Future randomized controlled trials are warranted to investigate the long-term effects of EA on blood flow of RIF patients and its implications for pregnancy outcomes.

Abstract
INTRODUCTION Persistently elevated thyroid stimulating hormone (TSH) despite levothyroxine (LT4) treatment that exceeds the standard weight-adjusted dose is a common clinical presentation. This may lead to additional testing for LT4 malabsorption or poor LT4 adherence, the latter of which is challenging to confirm because it is predicated on accurate patient accountability. CASE REPORT A 35-year-old lady, post-radioactive iodine therapy for Graves' disease remained euthyroid for a year on oral LT4. Two years later, she was clinically and biochemically hypothyroid despite claiming LT4 compliance. As all laboratory investigations were within the reference range, pseudomalabsorption was suspected and a LT4 absorption test was done. During the test, her free thyroxine increased significantly at 4 hours, reaching a peak of more than 50% from baseline while TSH decreased appropriately from 0 minute to 360 minutes. This was followed by normalisation of TSH with LT4 treatment under direct observation. DISCUSSION The LT4 absorption test is a prompt and economical means to rule out true malabsorption, decrease unwarranted subspecialty referrals and validate the weight-adjusted LT4 dose reduction.

Abstract
BACKGROUND Transvaginal oocyte retrieval is frequently followed by adverse events related to anesthesia and the procedure. Some research showed that transcutaneous electrical acupoint stimulation (TEAS) can relieve intraoperative pain and postoperative nausea. OBJECTIVE This study examined whether TEAS can alleviate pain and relieve adverse symptoms after oocyte retrieval. DESIGN, SETTING, PARTICIPANTS AND INTERVENTIONS Altogether 128 patients were randomly divided into the TEAS group and the mock TEAS group. The two groups received a 30-minute-long TEAS or mock TEAS treatment that began 30 min after oocyte retrieval. MAIN OUTCOME MEASURES The primary outcome was the visual analog scale (VAS) pain score. Secondary outcomes were pressure pain threshold, McGill score, pain rating index (PRI), present pain intensity (PPI), VAS stress score, VAS anxiety score, and postoperative adverse symptoms. RESULTS The baseline characteristics of the two groups were comparable (P > 0.05). The VAS pain scores of the TEAS group were lower than those of the mock TEAS group at 60 and 90 min after oocyte retrieval (P < 0.05). The McGill score, PRI and PPI in the TEAS group were significantly lower than those in the control group at 60 min after oocyte retrieval (P < 0.05). However, the two groups had equivalent beneficial effects regarding the negative emotions, such as nervousness and anxiety (P > 0.05). The TEAS group was superior to the mock TEAS group for relieving postoperative adverse symptoms (P < 0.05). CONCLUSION TEAS treatment can relieve postoperative pain and postoperative adverse symptoms for patients undergoing oocyte retrieval.

Abstract
Objectives The current study aims to assess the effectiveness of acupuncture in improving the live birth rate (LBR), ongoing pregnancy rate (OPR), clinical pregnancy rate (CPR), biochemical pregnancy rate (BPR), and pregnancy loss (early abortion rate, late abortion rate, ectopic pregnancy rate) in patients with recurrent implantation failure (RIF). Design This retrospective study compares the outcomes of patients with RIF who underwent frozen embryo transfer (FET) with or without acupuncture. Setting The medical records of patients diagnosed with RIF and visiting Chengdu Xi'nan Gynecological Hospital between January 2018 and June 2021 were reviewed. The Chengdu Xi'nan Gynecological Hospital Ethics Committee approved this retrospective study (No. 2021-029). Participants A total of 923 patients with RIF who underwent FET were included in this study. The patients were divided into two groups: the Acupuncture (n = 303) and the Non-acupuncture groups (n = 620). Exposure The Acupuncture group consisted of 303 RIF patients who received acupuncture therapy in addition to standard hormone replacement therapy (HRT)/delayed hormone replacement therapy (d-HRT) for FET. The Non-acupuncture group consisted of 620 RIF patients who received only standard HRT/d-HRT for FET. Primary and secondary outcome measures The primary outcome was the LBR. The secondary outcome referred to OPR, CPR, BPR, and pregnancy loss. Results The Acupuncture group had significantly higher BPR (P = 0.08) and CPR (P = 0.049) than the Non-acupuncture group. A potentially higher LBR (P = 0.16) and OPR (P = 0.248) were observed in the Acupuncture group than in the Non-acupuncture group. However, the survival analysis did not show that acupuncture significantly promoted live birth. Conclusions Acupuncture is an appropriate adjunctive technique in the in vitro fertilization process as it improves biochemical and clinical pregnancies. Therefore, it is necessary to be cautious about the role of acupuncture throughout the whole pregnancy cycle.

Abstract
Objective: To explore the influencing covariates of severe neutrophils and/or thrombocytopenia and their effect on treatment response and outcome in patients with chronic-phase chronic myeloid leukemia (CP-CML) receiving initial second-generation tyrosine kinase inhibitors (2G-TKI) . Methods: Data from consecutive patients aged ≥18 years with newly diagnosed CP-CML who received initial 2G-TKI at Peking University People's Hospital from September 2008 to November 2021 were interrogated. Binary logistic regression models and Fine-Gray and Cox regression models were applied. Results: Data from 267 patients who received initial 2G-TKI, including nilotinib (n=239, 89.5% ) and dasatinib (n=28, 10.5% ) , were interrogated. The median age was 36 (range, 18-73) years, and 156 (58.4% ) patients were male. At a median treatment period of 1.0 (0.1-3.0) month, 43 (16.1% ) patients developed grade ≥3 neutrophils and/or thrombocytopenia and recovered within 1.0 (0.1-24.6) month. Male (OR=2.9, 95% CI 1.2-6.8; P=0.018) , age of ≥36 years (OR=3.2, 95% CI 1.4-7.2, P=0.005) , a spleen below a costal margin of ≥7 cm (OR=2.8, 95% CI 1.2-6.6, P=0.020) , and a hemoglobin (HGB) level of <100 g/L (OR=2.9, 95% CI 1.3-6.8, P=0.012) at diagnosis were significantly associated with grade ≥ 3 neutrophils and/or thrombocytopenia. Based on their regression coefficients, male, age of ≥36 years, a spleen below a costal margin of ≥7 cm, and an HGB level of <100 g/L were given 1 point to form a predictive system. All patients were divided into three risk subgroups, and the incidence of severe cytopenia significantly differed among the three groups (P < 0.001) . Grade ≥3 neutrophils and/or thrombocytopenia for >2 weeks was significantly associated with lower cumulative incidences of complete cytogenetic response (CCyR, HR=0.5, 95% CI 0.3-0.7, P<0.001) and major molecular response (MMR, HR=0.4, 95% CI 0.3-0.8, P=0.004) and was not significantly associated with failure, progression, and survival. Conclusion: Male, advanced age, a large spleen, and a low HGB level were significantly associated with severe cytopenia. The four covariates were used to establish a prediction model, in which the incidence of severe cytopenia among different risk groups was significantly different. Severe cytopenia for >2 weeks was a negative factor for responses but not for outcomes.

Abstract
OBJECTIVE To determine the effect of acupuncture in treating poor ovarian response (POR). METHODS We searched MEDLINE (via PubMed), EMBASE, Allied and Complementary Medicine Database, CNKI, CBM, VIP database, Wanfang Database, and relevant registration databases from inception to January 30, 2023. In this review, both Chinese and English peer-reviewed literature were included. Only randomized controlled trials (RCTs) using acupuncture as an intervention for POR patients undergoing in vitro fertilization were considered. RESULTS Seven clinical randomized controlled trials (RCTs) were eventually included for comparison (516 women). The quality of included studies was generally low or very low. For the meta-analysis, seven studies showed that compared with controlled ovarian hyperstimulation (COH) therapy, acupuncture combined with COH therapy could significantly increase the implantation rate (RR=2.13, 95%CI [1.08, 4.21], p=0.03), the number of oocytes retrieved (MD=1.02, 95%CI [0.72, 1.32], p<0.00001), the thickness of endometrium (MD=0.54, 95%CI [0.13, 0.96], p=0.01), and the antral follicle count (MD=1.52, 95%CI [1.08, 1.95], p<0.00001), reduce follicle-stimulating hormone (FSH) levels (MD=-1.52, 95%CI [-2.41, -0.62], p=0.0009) and improve estradiol (E2) levels (MD=1667.80, 95%CI [1578.29, 1757.31], p<0.00001). Besides, there were significant differences in the duration of Gn (MD=0.47, 95%CI [-0.00, 0.94], p=0.05) between the two groups. However, no statistical variation was observed in improving clinical pregnancy rate (CPR), fertilization rate, high-quality embryo rate, luteinizing hormone (LH) value, anti-mullerian hormone (AMH) value, or reducing the dose of gonadotropin (Gn) values between the acupuncture plus COH therapy group and the COH therapy group. CONCLUSION Acupuncture combined with COH therapy is doubtful in improving the pregnancy outcome of POR patients. Secondly, acupuncture can also improve the sex hormone level of POR women, and improve ovarian function. Furthermore, more RCTs of acupuncture in POR are needed to be incorporated into future meta-analyses. SYSTEMATIC REVIEW REGISTRATION PROSPERO, identifier CRD42020169560.

Abstract
Background The neural activity of irritable bowel syndrome (IBS) patients in the resting state without any intervention has not been systematically studied. The purpose of this study was to compare the resting-state brain functions of IBS patients with healthy controls (HCs). Methods The published neuroimage studies were obtained from electronic databases including PubMed, EMBASE, PsycINFO, Web of Science Core, CNKI Database, Wanfang Database, VIP Database, and CBMdisc. Search dates were from inception to March 14th, 2022. The studies were identified by the preidentified inclusion and exclusion criteria. Two independent reviewers compiled the studies and evaluated them for quality and bias. Results Altogether 22 fMRI studies were included in this review. The risk of bias of the included studies was generally low. The findings indicated that in IBS patients, increased or decreased brain areas were mostly associated with visceral sensations, emotional processing, and pain processing. According to brain network research, IBS may exhibit anomalies in the DMN, CEN, and emotional arousal networks. The fluctuations in emotion (anxiety, sadness) and symptoms in IBS patients were associated with alterations in the relevant brain regions. Conclusion This study draws a preliminary conclusion that there are insufficient data to accurately distinguish the different neurological features of IBS in the resting state. Additional high-quality research undertaken by diverse geographic regions and teams is required to reach reliable results regarding resting-state changed brain regions in IBS.

Abstract
OBJECTIVE To evaluate the efficacy and safety of 585 nm Q-switched laser in the treatment of acne inflammatory lesions and postinflammatory erythema. METHODS A total of 25 patients with moderate facial acne, symmetrical distribution of inflammatory lesions and postinflammatory erythema on both sides of the face, were enrolled. Among the 25 patients, 22 patients completed all the treatment and evaluation, and 3 patients were lost to follow-up. 585 nm Q-switched laser was used on a randomly selected side of the face for three times of treatment at a 2 week interval. The evaluations were made before each treatment, 2 and 4 weeks after the last treatment, therefore the evaluation time points were before the treatment, weeks 2, 4, 6, and 8, respectively, for a total of 5 times. Acne severity was assessed using the investigator' s global assessment (IGA) score, and erythema severity was assessed using the investigator' s subjective erythema score and narrow-spectrum reflectance spectrophotometer at each follow-up. RESULTS After 3 times of treatment, there was statistically significant difference between the IGA score in week 8 and before treatment on both sides(Z=2.64, P < 0.01; Z=2.67, P < 0.01). There was no significant difference in IGA score between the treatment side and the control side before treatment and in week 8 (P=0.59, P=0.26). There was statistically significant difference between the investiga-tor' s subjective erythema score in week 8 and before treatment on the treatment side(Z=4.24, P < 0.01), while no significant difference was showed on the control side(Z=1.73, P=0.08). In week 8, the investigator's subjective erythema score of the treatment side was lower than that of the control side (Z=3.61, P < 0.01). The erythema index of the treatment side was significantly decreased at 5 time points (P < 0.01), and the index decreased significantly in week 8 compared with the index before treatment (P < 0.01), while the erythema index of the control side was not significantly different at 5 time points. The treatment related adverse events included erythema and edema after treatment and pain during treatment, the severity was mild to moderate, which resolved spontaneously within 1 to 3 days. Nine patients were very satisfied with the treatment, 7 patients were satisfied, and 6 patients considered average. CONCLUSION 585 nm Q-switched laser has some effect in the treatment of postinflammatory erythema, and it ensures good tolerance and safety. There was no statistically significant difference between the treatment side and the control side on the improvement of acne inflammatory lesions.

Abstract
Low-dimensional chiral organic-inorganic hybrid metal halides have attracted a lot of attention in recent years due to their unique intrinsic properties, including having potential applications in optoelectronic and spintronic devices. However, low-dimensional chiral molecular ferroelectrics are very rare. In this paper, we report a novel zero-dimensional molecular ferroelectric (C9H14N)2CdBr4 (C9H14N+ = protonated 3-phenylpropylamine), which has obvious dielectric and thermal anomalies and shows a high Curie temperature at 395 K. It crystallizes in the P21 space group at room temperature, showing a strong CD signal, large spontaneous polarization (P s = 13.5 μC cm-2), and a clear ferroelectric domain. In addition, it also exhibits a flexible SHG response. The photoluminescence spectrum shows that 1 has broadband luminescence. At the same time, compound 1 has a wide band gap, which is mainly contributed to by the inorganic CdBr4 tetrahedron. The high tunability of low-dimensional chiral molecular ferroelectrics also opens up a way to explore multifunctional chiral materials.

Abstract
Objective: To explore whether blood and polyp tissue eosinophil numbers are independent risk factors for poor disease control in patients with nasal polyp. Methods: By using the electronic medical records database and manual evaluation, 183 nasal polyp patients who had undergone endoscopic sinus surgery at least one year prior to the study with complete data of tissue specimens, baseline blood routine test, nasal endoscopy and sinus computed tomography, were identified and recruited to assess disease control based on the criteria of a European Position Paper on Rhinosinusitis and Nasal Polyps 2012 (EPOS 2012). Multiple logistic regression model was used to determine the association between blood and tissue eosinophil numbers and risk of poor disease control by adjusting for demographics and comorbidities. Results: We broke down the cohort into 4 groups according to blood (0.3×109/L) and tissue (10%) eosinophils. The patients without eosinophilic inflammation represented the largest group (41.5%). The group with concordant blood and tissue eosinophilia represented the second largest (31.2%), and the patients with isolated tissue (15.3%) or blood (12.0%) eosinophilia were relatively rare. Multiple logistic regression models found blood eosinophil count and tissue eosinophil percentage were independently associated with increased risk for poor disease control after adjustments for covariates related to poor treatment outcome. Furthermore, subjects with concordant blood and tissue eosinophilia had a higher risk for poor disease control than those with isolated blood or tissue eosinophilia. Conclusion: Concordant blood and tissue eosinophilia relates to a higher likelihood of poor disease control than isolated blood or tissue eosinophilia after adjustment of potential confounders in nasal polyp patients.

Abstract
In this study, we evaluated the body fat distribution and fatty acid composition of muscles and adipose tissues of Yangzhou geese, including thirty 60-day-old goslings (15 males and 15 females) and 20 320-day-old geese (10 males and 10 females). Adipose tissues of Yangzhou geese were distributed widely and could be divided into 5 types: subcutaneous fat, abdominal fat, sartorial fat, neck fat, and mesenteric fat. Higher contents of abdominal fat, sartorial fat, neck fat, and mesenteric fat but a lower content of subcutaneous fat were found in adult geese than in goslings (P ≤ 0.05). Adult female geese deposited more fat than adult male geese (P ≤ 0.05). No difference was found in the fat distribution and fat content between male and female goslings (P > 0.05). The breast muscle of adult geese was characterized by a higher content of total monounsaturated fatty acids (ΣMUFAs) and a lower content of n-6 polyunsaturated fatty acids (ΣPUFAs n-6) than that of goslings (P ≤ 0.05). Lower concentrations of total saturated fatty acids and ΣPUFA were found in adult female geese than in female goslings (P ≤ 0.05). In comparison with adult female geese, the breast muscle of adult male geese had higher total saturated fatty acids and stearic acid (P ≤ 0.05). For the thigh muscle, adult female geese had a higher ΣMUFAs content than adult male geese (P ≤ 0.05). In adipose tissues, adult geese had a higher Σn-6/Σn-3 ratio but had lower contents of erucic acid, linolenic acid, arachidonic acid, docosatetraenoic acid, and ΣPUFA n-3 than goslings, and adult female geese had a higher ΣMUFAs content than adult male geese (P ≤ 0.05). In conclusion, adult geese, especially adult female geese, accumulated more fat than goslings. Both age and sex affected the fatty acid composition of muscles and adipose tissues in geese. This research provides essential information not only for the nutritional evaluation of geese but also for the consumption and processing of goose products.

Abstract
Objectives: To explore BCR-ABL kinase domain mutation profiles and clinical variables associated with them in tyrosine kinase inhibitor (TKI) -resistant patients with chronic myeloid leukemia (CML) . Methods: Imatinib-, nilotinib-, and/or dasatinib-resistant patients with CML who screened BCR-ABL mutation (s) in Peking University People's Hospital between June 2001 and September 2019 were retrospectively reviewed. BCR-ABL mutation was analyzed by Sanger sequencing. Binary logistic regression model was built to identify independent clinical variables associated with developing BCR-ABL mutation (s) . Results: Data of 1 093 TKI-resistant cases in 804 patients who experienced resistance to imatinib (n=576, 52.7%) , nilotinib (n=238, 21.8%) , and dasatinib (n=279, 25.5%) were analyzed. In total, 291 (50.5%) imatinib-, 152 (63.9%) nilotinib-, and 160 (57.3%) dasatinib-resistant cases developed BCR-ABL mutation (s) . T315I mutation was the most frequent mutation detected in imatinib-, nilotinib-, and dasatinib-resistant cases, accounting for 12.3%, 27.3%, and 34.1%, respectively. Y253F/H (7.5%) and F359V/C/I (5.6%) were the mutation detected in ≥5% imatinib-resistant cases; F359V/C/I (12.2%) , Y253F/H (11.8%) , and E255K/V (10.5%) in nilotinib-resistant cases; and F317L/V/I/C (11.5%) and E255K/V (5.4%) in dasatinib-resistant cases. In multivariate analyses, no TKI dose reduction or discontinuation of TKI therapy was the common variable associated with developing BCR-ABL mutation (s) . Other variables associated with developing BCR-ABL mutation (s) in imatinib-, nilotinib-, or dasatinib-resistant cases included male gender, younger age, no comorbidity, advanced phase before starting current TKI therapy, longer interval from diagnosis to starting current TKI therapy, acquired resistance, and TKI resistance due to progression to advanced phase or hematologic failure. In addition, interval from TKI failure to BCR-ABL mutation detection, starting initial TKI therapy to TKI failure, and starting current TKI therapy to TKI failure were associated with the frequency of developing BCR-ABL mutation. Dasatinib and nilotinib use and acquired resistance were identified to be associated with the development of T315I mutation in multivariate analyses. Conclusions: More than half of TKI-resistant CML patients developed BCR-ABL mutation (s) by Sanger sequencing. T315I mutation was the most frequently detected. Clinical variables significantly associated with developing BCR-ABL mutation (s) should be used not only as basis for the choice of subsequent TKIs but also the understanding of TKI-resistant mechanisms.

Abstract
Objective: To compare the cytogenetic and molecular responses, outcomes and severe hematologic toxicity of nilotinib and imatinib as frontline therapy in newly diagnosed patients with chronic myeloid leukemia in chronic phase (CML-CP) . Methods: Newly diagnosed CML-CP patients were consecutively recruited from January 2006 to December 2018 who received nilotinib and imatinib as first-line treatment. Clinical data were retrospectively analyzed. Results: A total of 524 patients were classified into 439 (83.8%) receiving imatinib and 85 (16.2%) receiving nilotinib. Comparing with imatinib group, patients in nilotinib group were much younger (P=0.019) and more with intermediate and high Sokal risks (P<0.001) , WBC ≥100×10(9)/L (P<0.001) , HGB<120 g/L (P<0.001) , blast cells in bone marrow (P=0.026) , splenomegaly (P<0.001) by physical examination at diagnosis, and longer interval from diagnosis to TKI treatment (P=0.003) . With a median TKI duration of 57 (range 3-153) months, the probabilities of complete cytogenetic response (CCyR) (P=0.011) , major molecular response (MMR) (P=0.001) and MR(4.5) (P=0.046) were much higher in nilotinib group than those in imatnib according to each risk group. There is no statistical significance on probabilities of failure free survival (FFS) , progression free survival (PFS) and overall survival (OS) at 6 years between the two groups. Multivariate analyses showed that imatinib was an adverse factor associated with achieving CCyR (OR=0.6, 95% CI 0.5-0.8, P=0.001) , MMR (OR=0.6, 95% CI 0.5-0.9, P=0.032) and MR(4.5) (OR=0.6, 95%CI 0.5-0.9, P=0.032) and poor FFS (OR=1.9, 95%CI 1.0-3.4, P=0.041) . In addition, Sokal score was an independent factor affecting cytogenetic and molecular responses, treatment failure, disease progression and survival. Male, WBC ≥100×10(9)/L or HGB<120 g/L at diagnosis were significantly associated with lower cytogenetic and molecular response rates and/or poor FFS. The severe hematologic adverse events were not associated with different TKIs. Conclusions: Nilotinib reaches to the faster and deeper cytogenetic and molecular responses and significantly improves FFS than imatinib in newly diagnosed patients with CML-CP.

Abstract
Objective: To evaluate the efficacy of consolidation chemotherapy combined with allogeneic natural killer (NK) cell infusion in the treatment of low or intermediate-risk (LIR) acute myeloid leukemia (AML) . Methods: A cohort of 23 LIR AML patients at hematologic complete remission (CR) received NK cell transfusion combined with consolidation chemotherapy after 3 consolidation courses from January 2014 to June 2019 were reviewed. Control group cases were concurrent patients from Department of Hematology, and their gender, age, diagnosis, risk stratification of prognosis, CR and the number of courses of consolidate chemotherapy before NK cell transfusion were matched with LIR AML patients. Results: A total of 45 times of NK cells were injected into 23 LIR AML patients during 4 to 7 courses of chemotherapy. The median NK cell infusion quantity was 7.5 (6.6-8.6) ×10(9)/L, and the median survival rate of NK cells was 95.4% (93.9%-96.9%) . Among them, the median CD3(-)CD56(+) cell number was 5.0 (1.4-6.4) ×10(9)/L, accounting for 76.8% (30.8%-82.9%) ; The number of CD3(+) CD56(+) cells was 0.55 (0.24-1.74) ×10(9)/L, accounting for 8.8% (4.9%-20.9%) . Before NK cell infusion, the number of patients with positive MRD in the treatment and control groups were 9/23 (39.1%) and 19/46 (41.3%) (χ(2)=0.030, P=0.862) respectively. After NK infusion, There was no significant difference in terms of MRD that went from negative to positive between the treatment and the control groups (14.3% vs 22.2%, χ(2)=0.037, P=0.847) . In the treatment group, 66.7% (6/9) of the MRD were converted from positive to negative, which was significantly higher than that in the control group (10.5%, 2/19) (χ(2)=6.811, P=0.009) . Morphological recurrence occurred in 1 case of MRD negative in the treatment group and 2 cases of MRD positive in the control group. By the end of follow-up, the median follow-up was 35 (10-59) months, the number of patients with morphological recurrence in the treatment group was 30.4% (7/23) , which was significantly lower than that in the control group (50.2%, 24/46) (χ(2)=2.929, P=0.087) , although there was no statistically significant difference between the two groups. There was no significant difference on MRD-negative between the treatment and the control groups (43.5% vs 43.5%, χ(2)=1.045, P=0.307) . The 3-year leukemia-free survival was better in the treatment group [ (65.1±11.1) %] than that in the control group [ (50.0±7.4) %] (P=0.047) . The 3-year overall survival in the treatment and control groups were (78.1±10.2) % and (65.8±8.0) % (P=0.212) , respectively. Conclusion: The consolidation of chemotherapy combined with allogeneic NK cell infusion contributed to the further remission of patients with LMR AML and the reduction of long-term recurrence.

Abstract
1. PercollTM is one of the most widely used colloid for animal sperm preparation. The aim of this study was to evaluate whether PercollTM colloid centrifugation could be practical to improve cockerel sperm quality, and to compare the effects of PercollTM single layer centrifugation (SLC) and density gradient centrifugation (DGC) in order to obtain the most optimal protocol for cockerel semen.2. In the experiment with PercollTM SLC for fresh semen, an increase of motile sperm was seen after PercollTM 80% SLC and 90% SLC was conducted, at levels of 28.8% and 30.2% respectively (P < 0.01). The increase of progressively motile sperm after PercollTM 80% SLC and 90% SLC was 177.2% and 202.4% respectively (P < 0.01). Meanwhile, for semen stored at 4°C for 24 h, the increase of motile sperm after PercollTM 70% SLC and 80% SLC was 41.2% and 44.0% (P < 0.01), and the increase of progressive sperm after PercollTM 70% SLC and 80% SLC was 71.3% and 83.1% respectively (P < 0.01). Both the percentage of motile sperm and progressive sperm of the fresh and stored cockerel semen after appropriate PercollTM SLC was significantly enhanced.3. Sperm membrane integrity did not show any decrease after PercollTM centrifugation compared with non-centrifuged semen, which suggested that the PercollTM centrifugation treatment in this study did not cause damage to cockerel sperm membranes.4. In the experiment regarding the comparison of PercollTM SLC and DGC with fresh semen, the increase of motile sperm after PercollTM 80% SLC, 90% SLC and 40%/80% DGC was 29.5%, 36.4%, and 25.0% respectively; and the increase of progressive sperm was 44.7%, 58.5%, and 54.7%, respectively. For semen stored at 4°C for 24 h, the increase of motile sperm after PercollTM 70% SLC, 80% SLC and 35%/70% DGC were 41.2%, 44.0%, and 26.4%; and the increase of progressive sperm was 71.3%, 83.1%, and 43.7%, respectively. There were no significant differences between the increase of sperm motility after PercollTM 80%, 90% SLC or PercollTM 40%/80% DGC in fresh cockerel semen. There was no significant difference between PercollTM 70%, 80% SLC and PercollTM 35%/70% in stored cockerel semen. There was a tendency for sperm recovery rates with PercollTM SLC to be higher than PercollTM DGC, although this did not reach statistical significance in this study.5. It was concluded that PercollTM SLC was more suitable for cockerel sperm separation than PercollTM DGC. The results suggested that PercollTM 80% SLC was the most optimal procedure to separate fresh cockerel sperm and PercollTM 70% SLC was the most optimal procedure to separate stored cockerel sperm. PercollTM SLC is more simple, user-friendly and economical and less time-consuming than DGC for cockerel semen processing.

Methods: The clinical manifestations, MRI, EEG, treatment and prognosis of 16 patients with TMT poisoning were analyzed retrospectively. Results: Among the 16 cases of TMT poisoning, 6 cases were severe poisoning, 4 cases were moderate poisoning, and 6 cases were mild poisoning. All patients had dizziness, headache, general fatigue, loss of appetite, nausea, vomiting and other general clinical symptoms. Six patients with severe poisoning had psychobehavioral abnormalities, including 4 patients with mania, delirium, ataxia, epileptic seizures. Glasgow was 15 points in mild and moderate poisoning. Of the 6 cases of severe poisoning, 4 cases of Glasgow were 9~11 points, and 2 cases of Glasgow were 13 points. 2 patients with severe poisoning had abnormal MRI in head, and the total abnormal rate was 12.50%. Toxic encephalopathy was considered in 1 case with abnormal signal of corpus callosum pressure, and patchy ischemic foci of left cerebral foot and mild cerebral atrophy in 1 case. The total abnormal rate of EEG was 56.25%. The abnormal rate of electroencephalogram in severe poisoning was 83.33%. There were 2 cases of severe abnormal electroencephalogram, 2 cases of moderate abnormal electroencephalogram and 1 case of slight abnormal electroencephalogram. Twelve patients were recovered and discharged from hospital. 4 cases of severe poisoning are still getting better, and there are still cerebellar ataxia symptoms such as dizziness and unstable walking. Conclusion: In clinical work, attention should be paid to the identification of patients with mild and moderate TMT poisoning, and attention should be paid to the patients with severe TMT poisoning manifested by disturbance of consciousness. The positive rate of MRI test in TMT poisoning is low, and the lesion is nonspecific. Electroencephalogram test has a high positive rate in TMT poisoning, which can well reflect the degree of illness. Attention should be paid to the prevention and treatment of neurodegeneration caused by TMT poisoning.

Abstract
Objective: To compare the clinical features between the 2 cohorts developing myelodysplastic syndrome or acute myeIogenous Ieukemia in Philadelphia chromosome-negative cells (Ph(-) MDS/AML) and maintaining disease stable in the patients with Philadelphia chromosome-positive chronic myeloid Ieukemia (Ph(+) CML) who had clonal chromosomal abnormalities in Philadelphia chromosome-negative metaphases (CCA/Ph(-)) during tyrosine kinase inhibtor (TKI) - therapy. Methods: We retrospectively analyzed Ph(+) CML patients who developed CCA/Ph(-) during TKI-therapy from May 2001 to December 2017. Results: Data of CCA/Ph(-) 63 patients, including 7 progressing to Ph(-) MDS/AML and 56 remaining disease stable were collected. Compared with those with stable disease, patients with Ph(-)MDS/AML had lower hemoglobin (P=0.007) and platelet (P=0.006) counts, and higher proportion of peripheral blasts (P<0.001) when the first time CCA/Ph(-) was detected, and more mosonomy 7 abnormality (5/7, 71.4%) when MDS or AML was diagnosed; meanwhile, trisomy 8 (32/56, 57.1%) was more common in those with stable disease. Outcome of the patients with Ph(-) MDS/AML were poor. However, most of those with CCA/Ph(-) and stable disease had optimal response on TKI-therapy. Conclusions: A few patients with Ph(+) CML developed CCA/Ph(-) during TKI-therapy, most of them had stable disease, but very few patients developed Ph(-) MDS/AML with more common occurrence of monosomy 7 or unknown cytopenia. Our data suggested the significance of monitoring of peripheral blood smear, bone marrow morphology and cytogenetic analysis once monosomy 7 or unknown cytopenia occurred.

Abstract
Objective: To investigate the expression of 11β-hydroxysteroid dehydrogenase (11β-HSD) in polyps of patients with chronic rhinosinusitis with nasal polyps (CRSwNP) and its correlation with glucocorticoid sensitivity. Methods: The prospective study method was applied. Forty-three adult CRSwNP patients from Otorhinolaryngology Hospital, First Affiliated Hospital of Sun Yat-sen University between April 2016 and June 2017 were enrolled in this study. There were 19 males and 24 females with the age of (37.44±7.42) years old. The endoscopic scores by nasal Polyps Grading System before and after one-week prednisone treatment (0.5 mg/(kg·d)) were evaluated. The response of glucocorticoid by the total endoscopic scores was estimated. According to the patient's reduced nasal polyp endoscopic score, patients were devided into nasal polyps insensitive to glucocorticoids treatment group (insensitive group) and nasal polyp sensitive to glucocorticoids treatment group (sensitive group). The expression of 11β-HSD1, 11β-HSD2 in nasal polyps were measured by Real-time PCR (RT-PCR), Western Blot and immunohistochemisty. According to the clinical data, the Logistic regression models and receiver operation characteristics (ROC) curves were used to explore the predictor for glucocorticoid response in CRSwNP. Results: The expression of 11β-HSD1 and 11β-HSD1/11β-HSD2 was higher in sensitive group than that of insensitive group, while the expression of 11β-HSD2 was lower (rank average was 26.08 vs 16.33, 27.24 vs 14.72, 18.66 vs 26.64, Z value was -2.511, 0.323, -2.059, respectively, all P<0.05). The endoscopic scores in CRSwNP group declined whereas the expression of 11β-HSD1/11β-HSD2 increased (r=0.528, P=0.001), while the cutoff value of the ratio of 11β-HSD1/11β-HSD2 was 2.290 (sensitivity was 79.17%, specificity was 88.89%). Conclusions: There is a positive correlation between the response of glucocorticoid and the ratio of 11β-HSD1/11β-HSD2, which could be used as a marker in predicting the level of tissue response to glucocorticoid therapy in CRSwNP.

Abstract
Objective: To explore the clinical features, diagnostic methods and therapeutic strategy of silent sinus syndrome (SSS). Methods: A retrospective study was made on eight SSS patients treated during 2013-2016 in Longgang ENT Hospital and Otorhinolaryngology Hospital of the First Affiliated Hospital of SUN Yat-sen University. The following clinical data, including demographic data, symptoms, history of trauma and surgery, signs, imaging examination, endoscopic surgery and postoperative outcomes, were analyzed to summarize the diagnosis and treatment experiences. Results: Eight SSS patients showed the following clinical features: the proportions of both sexes and sinus sides were 4 to 4; seven cases (7/8) were adult, with an average of (48.1±11.8)y; seven cases (7/8) had long history of trauma or surgery, with an average of (17.9±10.5)y; seven cases (7/8) cannot recall the exact course of SSS; six cases (6/8) had no nasal symptoms; eight cases (8/8) had unilateral ocular discomforts; eight cases (8/8) had signs of unilateral enophthalmos (2-5 mm), accompanied with hypoglobus; and by CT and MRI scanning, eight cases (8/8) showed the unilateral maxillary sinus outlet obstruction, sinus full opacification, sinus wall bony rarefaction, sinus wall contraction, sinus volume loss, and the ipsilateral orbital floor bowing descent and orbital volume increase. After treated by endoscopic sinus surgery and followed-up for one year, four cases were cured, and the other four improved; no intra- or post-operative complications occurred; and no individual need a two-stage orbital plastic reconstruction. Conclusions: SSS often develops in the unilateral maxillary sinus of adult patient with long history of trauma or surgery, but the nasal symptoms and signs are silent. Diagnostic for SSS depends on characteristic ocular sign and sinus CT imaging. Endoscopic sinus surgery helps to improve ocular and nasal signs and promote orbital self-reconstruction.

Abstract
Objective: To compare the cytogenetic response detected by conventional banding analysis (CBA) and fluorescence in situ hybridization (FISH) and to explore the correlation between the cytogenetic and molecular response in chronic myeloid leukemia (CML) patients during tyrosine kinase inhibitor (TKI) treatment. Methods: CBA, FISH and real-time quantitative reverse transcriptase polymerase chain reaction (RQ-PCR) methods were performed to detect the cytogenetic and molecular response simultaneously in 504 bone marrow samples from 367 CML patients who received TKI treatment. Results: Among 504 samples, 344 were detected to reach complete cytogenetic response (CCyR) by CBA, while 297 samples reached CCyR by FISH which were considered to carry BCR-ABL positive cells<1%. When the results of CBA, FISH and RQ-PCR were compared in 493 samples at the same time, it showed that in 337 samples with CBA-CCyR, 273 (81.0%) reached FISH-CCyR and 289 (85.8%) were BCR-ABL(IS) (International Scale, IS) ≤1% by RQ-PCR, compared to 9.0 (261/290) were BCR-ABL(IS) ≤1% among 290 samples with FISH-CCyR. There was no significant difference in the median value of BCR-ABL(IS) between samples in CBA-CCyR and FISH-CCyR (0.21% vs 0.13%, z=-1.875, P=0.061) . Furthermore, when the samples were divided into three groups according to BCR-ABL positive cells (0,>0~<1%, 1%~5%) by FISH, the statistical difference was observed, the proportion of samples with BCR-ABL(IS) ≤1% in the three groups were 94.1%, 57.6% and 27.7% respectively (χ(2)=43.499, P<0.001; χ(2)=9.734, P=0.003) , while the median value of BCR-ABL(IS) were 0.10%, 0.64% and 1.80% respectively (z=-5.864, P<0.001; z=-4.787, P<0.001) . Conclusion: FISH results were in good concordance with CBA in identify samples in CCyR, FISH was more sensitive and had better correlation with RQ-PCR results than CBA, but how to define FISH-CCyR need further study.

Abstract
Objective: To summarize the surgical techniques, benefits and limitations of transnasal endoscopic resection and optic nerve decompression for patients with optic neuropathy caused by fibro-osseous lesions. Methods: Eight patients with optic neuropathy caused by fibro-osseous lesions who accepted endoscopic surgery of either resection of the lesion or decompression of optic nerve in Otorhinolaryngology Hospital, First Affiliated Hospital of Sun Yat-sen University from 2007 to 2016 were retrospectively reviewed and followed until April, 2017. Analyses were performed on the pathology type, disease extent and disease duration, especially on the visual acuity and visual field changes before and after surgery. Results: Eight patients (5 male and 3 female) were included in this study, with a median age of 12 years old (8-19 years old). The median disease duration was 12 months (1-72 months). The visual acuity (VA) of five patients (40 cm/FC, 0.2, 0.1, 0.2, 10 cm/FC, respectively) improved after surgery (0.1, 0.3, 1.2, 0.1, 0.6, respectively), and one patient had no change of VA after the surgery. Two patients (0.02, hand movement, before surgery) became deprived of light perception (VA=0) immediately after surgery. One patient complicated with intra orbital hemorrhage because of anterior artery injury. No complications of cerebral spinal fluid leak, intra-ocular muscle injury, intra-cranial hemorrhage or brain tissue injury occurred. Conclusion: For the treatment of optic neuropathy caused by fibro-osseous lesions, transnasal endoscopic surgery might have a good outcome.

Abstract
Objective: To compare the efficacy and safety between Chinese generic imatinib (Xinwei®, Jiansu Hansoh Pharmaceutical Group Co., Ltd.) versus branded imatinib (Glivec®, Novartis) in patients with newly-diagnosed chronic myeloid leukemia in chronic phase (CML-CP). Methods: Patients with newly diagnosed CML-CP were enrolled and assigned to receive either Xinwei or Glivec at an initial dose of 400 mg/d according to patients' financial capability. The efficacy and adverse effects were evaluated. Results: From January 2014 to September 2015, 145 eligible patients were assigned to Xinwei (n=89) or Glivec (n=56) group. All patients were treated and followed up at least 3 months. At 3 months, the complete response rates were 95.5%(85/89) and 100%(56/56), major cytogenetic response rates were 74.2%(66/89) and 80.4%(45/56), and the proportions of achieving BCR-ALBIS≤10% were 76.1%(67/88) and 82.1%(46/56) in Xinwei and Glivec groups respectively (all P>0.05). With a median follow-up of 12 months, 2 patients in each group progressed to accelerate or blast phase. Hematologic and non-hematologic side effects were similar between the 2 groups. Conclusions: Early hematological, cytogenetic and molecular responses between Xinwei and Glivec are comparable in newly-diagnosed CML-CP patients. The progression rate and side effects are also similar between the 2 groups.

Abstract
OBJECTIVE To investigate the prognostic significance of proportion of the blasts in bone marrow on day 14 (D14) during induction chemotherapy in patients with adult Ph-negative acute lymphoblastic leukemia (Ph (-) ALL). METHODS Newly diagnosed Ph (-) ALL patients with bone marrow morphology analysis on day 14 during induction chemotherapy were analyzed retrospectively. The proportion of the D14 blasts which had an impact on achieving a CR by the first induction chemotherapy and outcomes were determined by ROC curve. RESULTS 166 ALL patients including 94 male and 72 female were analyzed. The median age was 32 years (range, 18-64 years). The CR rate by the first induction chemotherapy was 74.7% with a total CR rate as 93.3%. By ROC analysis, 7.5% of the D14 blasts had the best sensitivity and specificity. The patients with D14 blasts ≥7.5% had lower CR rates after the first and overall induction chemotherapy compared with those with D14 blasts <7.5% (42.7% vs 85.9%, P<0.001 and 75.9% vs 95.6%, P=0.001 respectively). The probabilities of 5-year disease free survival (DFS) and 5-year overall survival (OS) were higher in the patients with D14 blasts<7.5% than those with D14 blasts ≥7.5% (49.8% vs 29.6%, P=0.006 and 52.4% vs 32.6%, P=0.010 respectively). Multivariate analysis showed that higher WBC or central nervous system leukemia at diagnosis, D14 blasts ≥7.5%, no CR after the first induction chemotherapy and receiving consolidation and maintenance chemotherapy rather than transplant were associated with poor outcomes. CONCLUSIONS Higher proportion of D14 blasts in bone marrow during the first induction therapy indicated poor prognosis in adult Ph(-) ALL.

Abstract
Hedgehog signaling pathway is a conserved and important signaling pathway involved in proliferation and differentiation of many types of cells. Latest studies have found that Hedgehog signaling pathway may induce MSCs osteoblast differentiation by increasing the expression of the Runx2 and Osx and inhibit MSCs differentiate to adipocyte. Hedgehog signaling pathway may also promote osteoblast proliferation by regulating cyclin. This review summarizes the mechanism that Hedgehog signaling pathway regulates osteoblast differentiation and proliferation,and concludes that Hedgehog signaling pathway can regulate bone metabolism. It might provide new ideas for the treatment of osteoporosis.

Abstract
OBJECTIVES We aimed to provide a consensus statement by the International Rapid Eye Movement Sleep Behavior Disorder Study Group (IRBD-SG) on devising controlled active treatment studies in rapid eye movement sleep behavior disorder (RBD) and devising studies of neuroprotection against Parkinson disease (PD) and related neurodegeneration in RBD. METHODS The consensus statement was generated during the fourth IRBD-SG symposium in Marburg, Germany in 2011. The IRBD-SG identified essential methodologic components for a randomized trial in RBD, including potential screening and diagnostic criteria, inclusion and exclusion criteria, primary and secondary outcomes for symptomatic therapy trials (particularly for melatonin and clonazepam), and potential primary and secondary outcomes for eventual trials with disease-modifying and neuroprotective agents. The latter trials are considered urgent, given the high conversion rate from idiopathic RBD (iRBD) to Parkinsonian disorders (i.e., PD, dementia with Lewy bodies [DLB], multiple system atrophy [MSA]). RESULTS Six inclusion criteria were identified for symptomatic therapy and neuroprotective trials: (1) diagnosis of RBD needs to satisfy the International Classification of Sleep Disorders, second edition, (ICSD-2) criteria; (2) minimum frequency of RBD episodes should preferably be ⩾2 times weekly to allow for assessment of change; (3) if the PD-RBD target population is included, it should be in the early stages of PD defined as Hoehn and Yahr stages 1-3 in Off (untreated); (4) iRBD patients with soft neurologic dysfunction and with operational criteria established by the consensus of study investigators; (5) patients with mild cognitive impairment (MCI); and (6) optimally treated comorbid OSA. Twenty-four exclusion criteria were identified. The primary outcome measure for RBD treatment trials was determined to be the Clinical Global Impression (CGI) efficacy index, consisting of a four-point scale with a four-point side-effect scale. Assessment of video-polysomnographic (vPSG) changes holds promise but is costly and needs further elaboration. Secondary outcome measures include sleep diaries; sleepiness scales; PD sleep scale 2 (PDSS-2); serial motor examinations; cognitive indices; mood and anxiety indices; assessment of frequency of falls, gait impairment, and apathy; fatigue severity scale; and actigraphy and customized bed alarm systems. Consensus also was established for evaluating the clinical and vPSG aspects of RBD. End points for neuroprotective trials in RBD, taking lessons from research in PD, should be focused on the ultimate goal of determining the performance of disease-modifying agents. To date no compound with convincing evidence of disease-modifying or neuroprotective efficacy has been identified in PD. Nevertheless, iRBD patients are considered ideal candidates for neuroprotective studies. CONCLUSIONS The IRBD-SG provides an important platform for developing multinational collaborative studies on RBD such as on environmental risk factors for iRBD, as recently reported in a peer-reviewed journal article, and on controlled active treatment studies for symptomatic and neuroprotective therapy that emerged during the 2011 consensus conference in Marburg, Germany, as described in our report.

Abstract
The purposes of this research were to study the effects of two modified photocatalysts, Nafion-coated TiO(2) and fluorinated TiO(2), and photocatalytic degradation of Victoria Blue R in aqueous solution. Photocatalytic degradation of Victoria Blue R was accelerated by the modified photocatalysts. Bulk and surface characterizations of the resulting powders were carried out. Attachment of the anions to the TiO(2) surface using the Nafion-coated-TiO(2) possibly results in increased adsorption of the cationic dye, and the degradation rate is larger for the cationic dye. It was found that Victoria Blue R on the two illuminated TiO(2) surfaces underwent very different changes. To obtain a better understanding on the mechanistic details of this modified-TiO(2)-assisted photodegradation of the Victoria Blue R dye with UV irradiation, a large number of intermediates of the process were separated, identified, and characterized by a high-performance liquid chromatography-mass spectrometry technique. Several probable photodegradation pathways were proposed and discussed.

Abstract
Recent studies have indicated that the glycine receptor antagonist strychnine and the gamma-aminobutyric acid type A (GABA A) receptor antagonist bicuculline reduced the rapid-eye-movement (REM) sleep-specific inhibition of sensory inflow via the dorsal spinocerebellar tract (DSCT). These findings imply that the spinal release of glycine and GABA may be due directly to the REM sleep-specific activation of reticulospinal neurons and/or glutamate-activated last-order spinal interneurons. This study used in vivo microdialysis and high-performance liquid chromatography analysis techniques to provide evidence for these possibilities. Microdialysis probes were stereotaxically positioned in the L3 spinal cord gray matter corresponding to sites where maximal cerebellar-evoked field potentials or individual DSCT and nearby spinoreticular tract (SRT) neurons could be recorded. Glutamate, glycine, and GABA levels significantly increased during REM sleep by approximately 48, 48, and 14%, respectively, compared with the control state of wakefulness. In contrast, dopamine levels significantly decreased by about 28% during REM sleep compared with wakefulness. During the state of wakefulness, electrical stimulation of the nucleus reticularis gigantocellularis (NRGc) at intensities sufficient to inhibit DSCT neuron activity, also significantly increased glutamate and glycine levels by about 69 and 45%, respectively, but not GABA or dopamine levels. We suggest that the reciprocal changes in the release of glutamate, glycine, and GABA versus dopamine during REM sleep contribute to the reduction of sensory inflow to higher brain centers via the DSCT and nearby SRT during this behavioral state. The neural pathways involved in this process likely include reticulo- and diencephalospinal and spinal interneurons.

Abstract
Inflammatory events may contribute to the pathogenesis of Parkinson's disease (PD) and interleukin 1 (IL-1) may exert both neurotoxic and neuroprotective effects. We conducted a case-control study in a cohort of 493 PD cases and 388 ethnically matched controls to investigate the association of IL-1alpha C-889T and IL-1beta C-511T polymorphisms with the risk of PD. No significant difference in the genotype distribution of the analyzed polymorphisms was found between PD and controls. However, after stratification by age, individuals over 70 years of age carrying IL-1alpha-889 C/T genotype demonstrated a significant decrease in risk of developing PD (OR = 0.44; 95% CI = 0.22-0.88, p = 0.021) and the decrease is strengthened by IL-1beta-511 T-carrying genotype (OR = 0.28; 95% CI = 0.11-0.71, p = 0.008). Our data suggest that IL-1alpha, acting synergistically with IL-1beta, plays role in PD susceptibility among Taiwanese people older than 70 years of age.

Abstract
A complete suppression of muscle tone in the postural muscles and a reduction of muscle tone in the respiratory related musculature occur in rapid eye movement (REM) sleep. Previous studies have emphasized the role of glycine in generating these changes. Because the activity of norepinephrine- and serotonin-containing neurons is known to decrease in REM sleep, we hypothesized that a decrease in release in one or both of these transmitters might be detected at the motoneuronal level during muscle tone suppression elicited by brainstem stimulation in the decerebrate animal. We compared release in the ventral horn with that in the hypoglossal nucleus to determine whether the mechanism of muscle tone suppression differs in these nuclei as has been hypothesized. Electrical stimulation and cholinergic agonist injection into the mesopontine reticular formation produced a suppression of tone in the postural and respiratory muscles and simultaneously caused a significant reduction of norepinephrine and serotonin release of similar magnitude in both hypoglossal nucleus and spinal cord. Norepinephrine and serotonin release in the motoneuron pools was unchanged when the stimulation was applied to brainstem areas that did not generate bilateral suppression. No change in dopamine release in the motoneuron pools was seen during mesopontine stimulation-induced atonia. We hypothesize that the reduction of monoamine release that we observe exerts a disfacilitatory effect on both ventral horn and hypoglossal motoneurons and that this disfacilitatory mechanism contributes to the muscle atonia elicited in the decerebrate animal and in the intact animal during REM sleep.

Abstract
Orexin-A (OX-A) and orexin-B (OX-B) (hypocretin 1 and hypocretin 2) are synthesized in neurons of the perifornical, dorsomedial, lateral, and posterior hypothalamus. The locus coeruleus (LC) receives the densest extrahypothalamic projections of the orexin (OX) system. Recent evidence suggests that descending projections of the LC have a facilitatory role in the regulation of muscle tone. The pontine inhibitory area (PIA), located ventral to LC, receives a moderate OX projection and participates in the suppression of muscle tone in rapid-eye-movement sleep. We have examined the role of OX-A and -B in muscle-tone control using microinjections (0.1 microM to 1 mM, 0.2 microl) into the LC and PIA in decerebrate rats. OX-A and -B microinjections into the LC produced ipsi- or bilateral hindlimb muscle-tone facilitation. The activity of LC units was correlated with the extent of hindlimb muscle-tone facilitation after OX microinjections (100 microM, 1 microl) into fourth ventricle. Microinjections of OX-A and -B into the PIA produced muscle-tone inhibition. We did not observe any significant difference in the effect of OX-A and -B on muscle tone at either site. Our data suggest that OX release activates LC units and increases noradrenergic tonus in the CNS. Moreover, OX-A and -B may also regulate the activity of pontine cholinoceptive and cholinergic neurons participating in muscle-tone suppression. Loss of OX function may therefore disturb both facilitatory and inhibitory motor processes.

Abstract
Activation of the pontine inhibitory area (PIA) including the middle portion of the pontine reticular nucleus, oral part (PnO), or the gigantocellular reticular nucleus (Gi) suppresses muscle tone in decerebrate animals. The locus coeruleus (LC) and midbrain locomotor region (MLR) have been implicated in the facilitation of muscle tone. In the current study we investigated whether PIA and Gi stimulation causes changes in activity in these brainstem motor facilitatory systems. PIA stimulation evoked bilateral muscle tone suppression and inhibited 26 of 28 LC units and 33 of 36 tonically active units located in the anatomical equivalent of the MLR (caudal half of the cuneiform nucleus and the pedunculopontine tegmental nucleus). Gi stimulation evoked bilateral suppression of hindlimb muscle tone and inhibited 20 of 35 LC units and 24 of 24 neurons located in the MLR as well as facilitated 11 of 35 LC units. GABA and glycine release in the vicinity of LC was increased by 20-40% during ipsilateral PnO stimulation inducing hindlimb muscle tone suppression on the same side of the body. We conclude that activation of pontine and medullary inhibitory regions produces a coordinated reduction in the activity of the LC units and neurons located in the MLR related to muscle tone facilitation. The linkage between activation of brainstem motor inhibitory systems and inactivation of brainstem facilitatory systems may underlie the reduction in muscle tone in sleep as well as the modulation of muscle tone in the isolated brainstem.

Abstract
Electrical stimulation of circumscribed areas of the pontine and medullary reticular formation inhibits muscle tone in cats. In this report, we present an analysis of the anatomical distribution of atonia-inducing stimulation sites in the brain stem of the rat. Muscle atonia could be elicited by electrical stimulation of the nuclei reticularis pontis oralis and caudalis in the pons as well as the nuclei gigantocellularis, gigantocellularis alpha, gigantocellularis ventralis, and paragigantocellularis dorsalis in the medulla of decerebrate rats. This inhibitory effect on muscle tone was a function of the intensity and frequency of the electrical stimulation. Average latencies of muscle-tone suppressions elicited by electrical stimulation of the pontine reticular formation were 11.02 +/- 2.54 and 20.49 +/- 3.39 (SD) ms in the neck and in the hindlimb muscles, respectively. Following medullary stimulation, these latencies were 11.29 +/- 2.44 ms in the neck and 18.87 +/- 2. 64 ms in the hindlimb muscles. Microinjection of N-methyl-D-aspartate (NMDA, 7 mM/0.1 microliter) agonists into the pontine and medullary inhibitory sites produced muscle-tone facilitation, whereas quisqualate (10 mM/0.1 microliter) injection induced an inhibition of muscle tone. NMDA-induced muscle tone change had a latency of 31.8 +/- 35.3 s from the pons and 10.5 +/- 0. 7 s from the medulla and a duration of 146.7 +/- 95.2 s from the pons and 55.5 +/- 40.4 s from the medulla. The latency of quisqualate (QU)-induced reduction of neck muscle tone was 30.1 +/- 37.9 s after pontine and 39.5 +/- 21.8 s after medullary injection. The duration of muscle-tone suppression induced by QU injection into the pons and medulla was 111.5 +/- 119.2 and 169.2 +/- 145.3 s. Smaller rats (8 wk old) had a higher percentage of sites producing muscle-tone inhibition than larger rats (16 wk old), indicating an age-related change in the function of brain stem inhibitory systems. The anatomical distribution of atonia-related sites in the rat has both similarities and differences with the distribution found in the cat, which can be explained by the distinct anatomical organization of the brain stem in these two species.

Abstract
Stimulation of the nucleus magnocellularis (NMC) of the medulla produces changes in locomotion, muscle tone, heart rate, and blood pressure. Glutamatergic input has been found to modulate muscle tone, whereas cholinergic input has been found to mediate cardiovascular changes produced by stimulation of the NMC. The current study was designed to identify the brainstem afferents to NMC by using retrograde transport of wheat germ agglutinin and horseradish peroxidase (WGA-HRP) combined with glutamate and choline acetyltransferase (ChAT) immunohistochemical and nicotinamide adenine dinucleotide phosphate-diaphorase (NADPH-d) histochemical techniques. Fifty nanoliters of 2.5% WGA-HRP were microinjected into the NMC in the cat. A heavy density of WGA-HRP-labeled neurons was found in the ipsilateral mesencephalic reticular formation (MRF), periaqueductal gray, Kolliker-Fuse nucleus, and pontis centralis caudalis (PoC), in the contralateral pontis centralis oralis (PoO), and bilaterally in the nucleus paragigantocellularis lateralis. A moderate density of retrogradely labeled neurons was found in the ipsilateral side of the nuclei parvocellularis, retrorubral (RRN), PoO, and vestibular complex, in the contralateral PoC and nucleus gigantocellularis, and bilaterally in the inferior vestibular nucleus. Retrograde HRP/glutamate-positive cells could be found throughout the brainstem, with a high percentage in RRN, PoO, PoC, and MRF. Double-labeled WGA-HRP/ChAT neurons were found in the pedunculopontine nucleus. Double-labeled WGA-HRP/NADPH-d-positive neurons could be seen in many nuclei of the brainstem, although the number of labeled neurons was small. The dense glutamatergic projections to the NMC support the hypothesis that rostral brainstem glutamatergic mechanisms regulate muscle activity and locomotor coordination via the NMC, whereas the pontine cholinergic projections to the NMC participate in cardiovascular regulation.

Abstract
The dorsal regions of the midbrain and pons have been found to participate in sleep regulation. However, the physiological role of the ventral brainstem in sleep regulation remains unclear. We used N-methyl-D-aspartate-induced lesions of the ventral midbrain and pons to address this question. Unlike dorsal mesencephalic reticular formation lesions, which produce somnolence and electroencephalogram synchronization, we found that ventral midbrain lesions produce insomnia and hyperactivity. Marked increases in waking and decreases in slow wave sleep stage 1 (S1), stage 2 (S2) and rapid eye movement sleep were found immediately after the lesion. Sleep gradually increased, but never returned to baseline levels (baseline/month 1 post-lesion: waking, 30.6 +/- 4.58%/62.3 +/- 10.1%; S1, 5.1 +/- 0.74/3.9 +/- 1.91%; S2, 46.2 +/- 4.74%/23.1 +/- 5.47%; rapid eye movement sleep, 14.1 +/- 3.15%/7.2 +/- 5.42%). These changes are comparable in magnitude to those seen after basal forebrain lesions. Neuronal degeneration was found in the ventral rostral pons and midbrain, including the substantia nigra, ventral tegmental area, retrorubral nucleus, and ventral mesencephalic and rostroventral pontine reticular formation. We conclude that nuclei within the ventral mesencephalon and rostroventral pons play an important role in sleep regulation.

Abstract
The pontomedullary region is responsible for the reduction of muscle activity in rapid-eye-movement sleep and contributes to the control of muscle tone in waking. This study sought to clarify the nature of the interaction between the pontine and medullary reticular formation in mediating muscle tone suppression. The degree of medullary-induced neck muscle tone suppression in the decerebrate cat was assessed before and after microinjection of lidocaine into the pontine reticular formation. Medullary stimulation-induced suppression of neck muscle tone was blocked after pontine lidocaine microinjection. The maximum blockade was observed at 16.6 minutes on average after the injection, and recovery occurred within 45 minutes. We conclude that descending mechanisms from the medulla are not sufficient for the triggering of muscle tone suppression. A two-way interaction between the medulla and pons is hypothesized to play a crucial role in the control of muscle tone.
