ABSTRACT
Diminished ovarian reserve (DOR), generally defined as a decreased number or quality of oocytes, has a significant impact on quality of life and fertility in women. In recent years, the incidence of DOR has been increasing and the ages of patients are younger. The search for an effective DOR treatment has emerged as one of the preeminent research topics in reproductive health. An effective DOR therapy would improve ovarian function, fertility, and quality of life in patients. In this review we evaluated DOR treatment progress both in Western medicine and Chinese medicine, and elucidated the characteristics of each treatment.

Objective:To study the clinical features and prognostic risk factors of gastrointestinal (GI) involvement in systemic lupus erythematosus (SLE), and improve clinicians' understanding of GI involvement in SLE.Methods:The clinical data of SLE patients admitted to the First Affiliated Hospital of Guangxi Medical University from September 1, 2012 to September 1, 2019 were retrospectively analyzed. Two hundred and forty-three patients with GI system involvement were the GI system affected group, and 486 patients with-out GI system involvement at the same period were randomly selected as the control group. The clinical mani-festations, laboratory tests and treatment effects of the two groups were compared by t test, Wilcoxon signed-rank test and χ2 test and Logistic regression was used to analyze the prognostic risk of SLE with GI system involvement. Results:① There were 243 SLE patients with GI involvement, with the proportion of GI involvement in SLE patients of 6.4%(243/3 820), and as the first manifestation with GI system symptoms accounted for 20.2%(49/243). The common causes were lupus hepatitis accounted for 52.3%(127/243), lupus mesenteric vasculitis (LMV) for 35.0%(85/243), pseudo Intestinal obstruction (IPO) for 9.9%(24/243), lupus-related pancreatitis for 8.6%(21/243), and protein-losing enteropathy (PLE) as 7.0%(17/243). ② Compared with the control group, the group with GI involvement had a lower average age [(38±14) year vs(32±15) year, t=-2.47, P=0.014], a shorter median duration of illness [12.0(3.0, 72.0) months vs 5.0(1.1, 24.8) months, Z=-5.67 , P<0.001], a higher median systemic lupus erythematosus disease activity index (SLEDAI) score [10(6,28) vs 16(9, 37), Z=2.24 , P<0.001], the occurrence of skin rash (38.7% vs 53.5%, χ2=14.46), arthritis (36.4% vs 46.7%, χ2=7.12 , P=0.008), myositis (43.0% vs 56.4%, χ2=11.53 , P=0.001), pericarditis [(216±111)×10 9/L vs (175±114)×10 9/L, t=-4.69 , P<0.001], thrombocytopenia, and hydroureterosis (1.0% vs 12.8%, χ2=47.47 , P<0.001) were high, but the incidence of pulmonary arterial hypertension (PAH) (31.2% vs 10.7%, χ2=36.99 , P<0.001) was low; Serum alanine aminotransferase (ALT) [17(10, 29) U/L vs 59(16, 127) U/L, Z=9.65 , P<0.001], aspartate aminotransferase (AST) [25.0 (18.0, 37.0) U/L vs 82.5(25.0, 289.0) U/L, Z=10.57 , P<0.001], alkaline phosphatase (ALP) [58(46, 76) U/L vs 82(56, 187)U/L, Z=8.42 , P<0.001], Creatine kinase (CK) [44.0(28.0, 83.0) U/L vs 58.5(34.0, 176.0) U/L, Z=4.46 , P<0.001], lactate dehydrogenase (LDH) [(309±206) U/L vs (443±332) U/L, t=5.64 , P<0.001], fasting blood glucose (FBS) [(5.0±1.5) mmol/L vs (5.3±1.7) mmol/L, t=2.16 , P=0.031], triglyceride (TG) [(2.0±1.3) mmol/L vs (2.7±2.2) mmol/L, t=4.55 , P<0.001] increased, albumin (ALB) [(30±7) g/L vs (27±7) g/L, t=5.87 , P<0.001)] and high-density lipoprotein (HDL) [(1.1±0.8) mmol/L vs (0.9±0.5) mmol/L, t=-4.20 , P<0.001] decrease, and anti SSB antibody positive rate (16.0% vs 9.5%, χ2=5.60 , P=0.018) decreased.③ After 3 months' follow-up, 203 patients with SLE GI involvement were relieved, 30 patients (12.3%) died, and 9 patients (1.8%) died in the control group. Ninety-five (46.8%) patients in the remission group had a significantly higher rate of cyclophosphamide treatment when compared with 5(12.5%) in the non-remission group ( χ2=16.23, P<0.001) . Logistic regression analysis showed that no increase of PAH, elevated erythrocyte sedimentation rate (ESR), ALT, glutamyl transpeptidase (GGT), indirect bilirubin (IBIL) and high SLEDAI scores, hydroureteral dilatation, decreased ALB and HDL were independent related factors for SLE GI involvement, while ascites and elevated FBS were SLE GI involvement factors of poor prognosis. Conclusion:SLE patients with GI involvement have a high mortality rate, and lupus hepatitis and LMV are common. Hydroureterosis, high SLEDAI score, abnormal liver function are risk factors for GI involvement. Jaundice and elevated FBS are the risk factors for poor prognosis, and treatment with cyclophosphamide is the protective factor.
ABSTRACT
OBJECTIVE@#To evaluate the influence of different transcutaneous electrical acupoint stimulation (TEAS) modes on ovarian responses and pregnancy outcomes in patients with infertility undergoing in vitro fertilization and embryo transfer (IVF-ET).@*METHODS@#Two hundred infertility patients undergoing IVF-ET were divided randomly into experimental groups (TEAS groups: E-I, E-II, E-III, and E-IV, 40 cases each group) and a control group (mock TEAS group, 40 patients) using the random number method. The patients in the experimental groups received TEAS treatment of 20, 30, 40 and 50 mA for the E-I, E-II, E-III and E-IV groups, respectively. The control group received a treatment of 5 mA. TEAS was applied at acupoints of Guanyuan (RN 4), Zhongji (RN 3), Sanyinjiao (SP 6), Zigong (EX-CA 1), and Taixi (KI 13), once a day for 30 min each time for a treatment period of 10-13 d. Treatment effect was assessed using the following indicators: endometrial thickness on the 6th day of gonadotropin treatment (GN6 day), endometrial thickness on the day on chorionic gonadotropin administration (HCG day), number of ovarian follicles on HCG day, number of ova captured, amount of estrogen required for each harvested ova, number of mature ova divided by the total number of ova, percentage of high-quality embryos, and clinical pregnancy.@*RESULTS@#Endometrial thickness in the experimental groups on the HCG day was significantly better than that of the control group after TEAS stimulation (P=0.01). TEAS exhibited a greater impact on the number of ova captured (P=0.003). However, the effect of TEAS stimulation on the high-quality embryo rate and clinical pregnancy in patients was not statistically significant (P>0.05).@*CONCLUSIONS@#TEAS is an effective method in improving the ovarian state. When the stimulus intensity was at 40 mA and above, it could be helpful to improve the patient's endometrial condition and endometrial receptivity and to retrieve more oocytes.

Objective:To explore the predictive value of stroke-related early tracheotomy score (SET) for tracheotomy in neurocritical patients.Methods:A retrospective analysis of the clinical data of neurocritical patients admitted to the department of intensive care unit (ICU) of the Xindu District People's Hospital of Chengdu from January 1st to December 31st, 2019. Patients were divided into tracheostomy group and non-tracheostomy group according to whether they underwent tracheotomy during hospitalization; according to SET score, patients were divided into groups with SET score < 10 points and SET score ≥ 10 points. The differences in gender, age, acute physiology and chronic health evaluation Ⅱ (APACHEⅡ), Glasgow coma score (GCS), SET score, the length of ICU stay and mechanical ventilation time were compared between the two groups. The receiver operator characteristic curve (ROC curve) was used to analyze the predictive value of SET score for the length of ICU stay > 10 days, mechanical ventilation time > 5 days, and tracheotomy treatment, and the predictive value of APACHEⅡ score for tracheotomy treatment.Results:Among 66 patients, 35 cases underwent a tracheotomy, 31 cases did not; SET score < 10 points in 19 cases, while SET score ≥ 10 points in 47 cases. Compared with the non-tracheostomy group, there were more male patients in the tracheostomy group (cases: 27 vs. 13), the GCS score was lower (7.00±2.41 vs. 11.52±2.00), the APACHEⅡ score and the SET score were higher (22.43±4.45 vs. 19.58±5.86, 16.11±3.67 vs. 8.61±4.27), and the length of ICU stay and mechanical ventilation time was longer [days: 27.54±18.82 vs. 7.45±5.30, 13 (9, 19) vs. 0 (0, 2)], and all differences were statistically significant (all P < 0.05). Compared with SET score < 10 points group, the proportion of traumatic brain injury and tracheotomy in the SET score ≥ 10 points group was higher (44.68% vs. 15.79%, 70.21% vs. 5.26%), the GCS score was lower (8.00±2.87 vs. 11.89±1.97), APACHEⅡ score was higher (22.30±4.80 vs. 18.11±5.49), and the length of ICU stay and mechanical ventilation time was longer [days: 22.38±18.74 vs. 7.53±4.60, 9 (4, 16) vs. 0 (0, 2)], and the differences were statistically significant (all P < 0.05). ROC curve analysis showed that the area under the curve (AUC) of SET score predicting the length of ICU stay > 10 days of neurocritical patients was 0.877, and the 95% confidence interval (95% CI) was 0.790-0.964 ( P = 0.000), and its cut-off value was 13.50, the sensitivity was 80.0%, and the specificity was 87.1%. The SET score predicts the AUC for mechanical ventilation time > 5 days was 0.915, the 95% CI was 0.851-0.979 ( P = 0.000), the cut-off value was 13.50, the sensitivity was 78.4%, and the specificity was 89.7%. SET score predicts the AUC of tracheotomy treatment was 0.919, 95% CI was 0.853-0.985 ( P = 0.000), its cut-off value was 13.50, the sensitivity was 82.9%, and the specificity was 90.3%, which was significantly better than that of APACHEⅡ score in predicting the value of tracheotomy (AUC was 0.647, 95% CI was 0.512-0.783, P = 0.040, its cut-off value was 17.50, the sensitivity was 91.4%, and the specificity was 41.9%). Conclusion:SET score has a good predictive value for the length of ICU stay, mechanical ventilation time and tracheotomy in neurocritical patients.

In particular, the difference was statistically significant in the recovery period (P<0.01).@*CONCLUSIONS@#The prefrontal cortex was widely activated and produced an immediate effect by reducing the local blood oxygen concentration at low-frequency magnetic stimulation of Shenmen acupoint, which verifies the sedative effect of Shenmen acupoint.
ABSTRACT
Xiaoshuan Tongluo formula is effective in treating mental retardation and speech astringency caused by cerebral thrombosis, but its mechanism remains unclear. In this investigation, by collecting the chemical constituents from Xiaoshuan Tongluo formula and the targets related to stroke, we obtained 1 251 constituents from the formula and 10 drug targets related with stroke. We established 18 prediction models of compound-target interaction for 10 stroke-related targets, using molecular docking method and machine learning methods includes Naive Bayesian and recursive partitioning based on the input of molecular fingerprints and molecular descriptors. Using these models, we predicted the active chemical constituents from Xiaoshuan Tongluo formula and their drug targets, 153 potential active constituents were discovered, 22 among them could interact with at least two drug targets related with stroke. On this basis, the chemical constituent-target network was constructed using network construction software, and then the important metabolic pathways of the targets were identified by using Gene-Ontology (GO) enrichment analysis, such as blood coagulation, positive regulation of angiogenesis, positive regulation of ion transport and so on. On this basis, a target-pathway network was constructed. In conclusion, using machine learning, molecular docking, virtual screening, data mining and network construction, this study explored and partially revealed the active chemical constituents and chemical constituent-target-pathway network action mechanism of Xiaoshuan Tongluo formula against stroke, which will provide important information for its further study.

ABSTRACT
Background@#With the development of assisted reproductive technology (ART) and its increasing success rate in the mainland of China, more attention has been paid to the safety of ART. In this study, we explored the associations between conception by ART and pregnancy/perinatal complications, and neonatal outcomes compared with similar outcomes following spontaneous conception.@*Methods@#This retrospective cohort study of pregnancies over a 3-year period (2013-2015) was performed at Beijing Obstetrics and Gynecology Hospital, Beijing, China. Subjects were divided into two groups: conception by ART (n = 2256) or spontaneous conception (n = 6768). According to different fertilization modes, the ART group was divided into in vitro fertilization (IVF, n = 1873) and intracytoplasmic sperm injection (ICSI, n = 383) subgroups. The ART group was also divided into two different embryo transfer methods; fresh embryo transfer (ET, n = 1583) and frozen embryo transfer (FET, n = 673) subgroups. Pregnancy complications, perinatal complications, and neonatal outcomes of the enrolled subjects were investigated and analyzed by univariate analysis and multivariate logistic regression.@*Results@#After adjustment for maternal age, gravidity, parity, maternal education, smoking, alcohol consumption, and body mass index (BMI), pregnancies conceived by ART were associated with a significantly increased incidence of gestational diabetes mellitus (GDM; OR 1.88, 95% CI 1.56-2.27), gestational hypertension (OR 2.18, 95% CI 1.83-2.60), and intrahepatic cholestasis of pregnancy (ICP) (OR 2.79, 95% CI 2.15-3.64), compared with spontaneous conception. These associations were similar for the singleton group. In the twin group, only the incidence of ICP was significantly higher than in controls. We found that pregnancies conceived by ART were associated with perinatal complications, including placental abruption (OR 2.14, 95% CI 1.33-3.45), premature rupture of membranes (PROM; OR 1.24, 95% CI 1.06-1.45), postpartum hemorrhage (OR 2.89, 95% CI 2.33-3.59) and polyhydramnios (OR 2.01, 95% CI 1.29-3.16). The singleton group had a similar result with placental abruption, but not with fetal membranes ruptures before labor and polyhydramnios. There were no significant differences in the incidence of these perinatal complications in the twin group. Some neonatal outcomes, including preterm labor (OR 4.29, 95% CI 3.84-4.80) and low birth weight (OR 1.72, 95% CI 1.42-2.08), were more likely to occur with singleton births after ART. However, there were no significant differences for these outcomes from twin pregnancies. Perinatal complications and neonatal outcomes were consistent between the IVF and ICSI subgroups. The FET and ET subgroups showed a similar increase in complications, except for the incidence of placental abruption. After taking into account the effects of parity, birth plurality and maternal age, the ART group still exhibited increased maternal and neonatal complications, although some differences narrowed or disappeared.@*Conclusions@#This retrospective cohort study demonstrated that patients who underwent ART were at increased risk of several adverse pregnancy outcomes compared with women who conceived spontaneously. These complications may be attributed in part to the relatively high multiple pregnancy rate after ART. Elective single embryo transfer should be promoted in China to reduce the obstetrical risks of ART pregnancy. Singletons of ART pregnancy exhibited increased maternal and neonatal complications as well, suggesting that underlying infertility or other maternal or parental factors may contribute to the adverse outcomes.
ABSTRACT
Hemorrhagic transformation (HT) is a frequent complication of ischemic stroke, especially after thrombolytic therapy. This event is associated with increased morbidity and mortality. Tissue plasminogen activator (t-PA), the only FDA proved drug for breaking blood clots, is underutilized in ischemic stroke, because of its limited therapeutic window and hemorrhagic complications. Due to the lack of clear understanding of the pathological mechanism, there are no effective drugs to decrease the incidence of HT. Pinocembrin is a natural flavonoid compound and has neuroprotective effects in animal ischemic stroke models. In this study, we investigated the role of pinocembrin in t-PA thrombolysis-induced HT in rat thromboembolic stroke model. t-PA was administrated 6 h after ischemia and pinocembrin (5, 10 and 20 mg·kg-1) was given 5 min before t-PA administration. Infarct volume, neurological score and hemoglobin content were evaluated at 24 h after ischemia. Evans blue leakage was used to detect blood-brain barrier (BBB) permeability. All procedures were approved by the Institutional Animal Care and Use Committee of the Peking Union Medical College. The results showed that treatment with t-PA at 6 h after ischemia aggravated brain injury and increased the risk of HT, with infarct volume and brain water content reached 39% and 83.4%, respectively. Pretreatment with pinocembrin decreased the infarct volume and brain water content to 28.5% and 80.3%, and improved neurological function. In addition, the combined application of pinocembrin with t-PA reduced hemoglobin content and Evans blue content in brain tissue by 50% and 40%, indicating that pinocembrin could protect the BBB permeability and reduce the occurrence of HT. Among these doses, 10 mg·kg-1 is most effective. In conclusion, our results demonstrate that the combination of pinocembrin with t-PA protects against cerebral ischemia, reduces the occurrence of HT induced by t-PA thrombolysis. Thus, pinocembrin may be a potential therapeutic drug for t-PA induced HT.
ABSTRACT
This study was designed to compare the antithrombotic effects of salvianolic acid A and aspirin. The anti-platelet aggregation and anticoagulant effects of salvianolic acid A and aspirin in vitro and in vivo were investigated in normal rats. The anti-cerebral ischemia and anti-platelet aggregation effects of salvianolic acid A and aspirin were also investigated in rats with thrombotic cerebral ischemia. All animal care and experimental procedures were reviewed and approved by the Animal Ethics Committee of Chinese Academy of Medical Sciences. The results of antiplatelet aggregation in vitro and in vivo showed that salvianolic acid A could mildly inhibit adenosine diphosphate (ADP), arachidonic acid (AA) and thrombin (THR)-induced antiplatelet aggregation in a dose-dependent manner, while aspirin played a strong inhibitory effect on AA-induced platelet aggregation in vivo. The effects of salvianolic acid A and aspirin on the coagulation system were similar. At the same time, the results of maximum platelet aggregation rate (MAR) in the rat cerebral ischemia model [MARADP= (41.67±4.55)%, MARAA= (53.22±2.83)%, MARTHR= (73.33±5.04)%] indicated that salvianolic acid A could mildly inhibit ADP and AA-induced antiplatelet aggregation [MARADP= (26.13±4.60)%, MARAA= (35.53±13.73)%, P<0.01], while aspirin played a strong inhibitory effect on AA-induced platelet aggregation [MARAA= (8.13±2.99)%]. Salvianolic acid A (10 mg·kg-1) significantly improved the neurological function, cerebral infarction volume [(10.77±7.80)%] and brain edema [(79.72±0.83)%] compared with the model group [(43.50±12.69)%, (82.25±0.89)%] (P<0.01), while the effect of aspirin (100 mg·kg-1) was not obvious. The above results suggest that compared with aspirin, salvianolic acid A provided a mild inhibitory effect on platelet aggregation and protected against cerebral ischemia induced by thrombus. Therefore, salvianolic acid A has a good application prospect in the prevention and treatment of thrombotic diseases.

ABSTRACT
OBJECTIVE@#To observe and verify the key anatomies of DeLancey's three levels of vaginal support theory through laparoscopic surgery by space dissection technique.@*METHODS@#The features and stress performance of related anatomies were observed and analyzed in laparoscopic type C hysterectomy and pelvic lymphadenectomy for cervical cancer by natural space exposures.@*RESULTS@#The main ligament-like structure at level Ⅰ was the uterosacral ligament, which acted as the main apical fixation in the sacral direction, while the cardinal ligament was mainly composed of vascular system, lymph-vessels and loose connective tissue around them, lacking the tough connective tissue structures, which was connected to the internal iliac vascular system. There were no strong ligaments connected to the tendinous arch of pelvic fascia (ATFP) at the lateral side of vaginal wall at level Ⅱ. ATFP was the edge of the superior fascia of pelvic diaphragm, which was bounded by the fascia of the obturator. Its surface was smooth and close to the levator ani muscle and fuses with the vaginal fascia in about one thirds of middle lower segments of the vagina. When the ureter tunnel is separated, dense connective structures can be found in both anterior and posterior walls near the intersection of the ureter across uterine artery, fixing the bilateral angle of the bladder triangle, starting from the cervix and vagina and ending in the tunica muscularis vesicae urinariae.@*CONCLUSIONS@#Based on the laparoscopic anatomy, the pelvic floor fascia ligament support above the levator ani muscle can be considered mainly around the vagina, and fascial ligament above the levator ani muscle can be simply considered as two parallel planes forming a "double hammock" structure, which may provide more anatomic data for pelvic floor reconstruction.

Objective To study the factors that may influence the quality of life (QoL) in patients with systemic sclerosis (SSc) by comprehensively evaluating of the patient's condition and to provide evidence for appropriate selection of treatment.Methods Out-patients with SSc in the First Affiliated Hospital of Guangxi Medical University from November 2015 to October 2016 were retrospectively enrolled into this cross-sectional study.Their clinical data were collected.Consecutive SSc patients and 30 healthy controls were recruited and were assessed by the MOS-36 Item Short-Form Health Survey (SF-36),Health Assessment Questionnaire (HAQ),Visual Analogue Scale (VAS) and the St.George's Respiratory Questionaire (SGRQ).The extent of skin involvement of SSc was assessed by the Modified Rodnan skin score (MRSS).The SSc group was divided to diffused SSc (dcSSc) and localized SSc (lcSSc) according's to extent of skin involvement.Pearson's correlation analysis was used to assess the associated clinical indications with the QoL.Results ① Sixty-eight SSc patients were studied [mean age (52±11) years,mean disease duration (35±48) months],in which 59(87％)patients had Raynaud's pheno-menon,9(13％) patients hadfinger ulcer,16(24％) patients were complicated with PAH,and anti-Scl-70 antibody was positive in 59(87％) cases.② The SSc patients had significantly lower SF-36 scale score,including physical function (PF) (64±29),role-physical (RP) (53 ±33),bodily pain (BP)(66±19),social function (SF) (53±20),general health (GH) (58±24),vitality (VT) (53±18),role emotional (RE)(47±35),mental health (MH) (45±21),compared with the healthy-control group (t=7.726,7.132,8.586,12.29,8.296,9.526,6.893,13.973,4.384),all P＜0.01).The SSc patients had significantly higher scale scores of HAQ (t=1 1.823),VAS (t=19.578) and SGRQ (t=14.043,16.688,21.210,20.053),all P＜0.01.③ Compared with lcSSc patients,the SF-36 of dcSSc patient in the PF (F=17.035,P=0.030),RP (F=17.579,P=0.033),BP (F=23.002,P=0.032),VT (F=35.737,P=0.008) were decreased.The HAQ and VAS scale of dcSSc patients were significantly higher than lcSSc patients (F=42.541 and 110.243,P＜0.01).④ The PF,RP,VT,SF,MH of SF-36 scale score in SSc patients was inversely associated with HRCT scores (r=-5.088,-2.896,-2.566,-3.450,-4.173),MRSS (r=-3.847,-3.044,-2.651,-2.571,-2.455),but positively correlated with Complement3 (C3)(r=2.372,2.133,2.370,2.493,2.387).BP,and HAQ scores,VAS were associated with Raynaud's phenomenon (r=2.502,-2.683,-3.703) and MRSS (r=2.141,-2.683,-3.703).And VAS score was correlated with arthralgia (r=-2.943).The symptom score,activity score,influence score of SGRQ were negatively associated with HRCT score (r=4.001,-3.213,2.478),smoking-state (r=-3.040,-2.007,-2.218),all P＜0.05.Conclusion The SSc patients have impaired physical and mental function in the QoL,limited mobility,increased physical pain compared to healthy controls.DcSSc patients have worse QoL index compared with lcSSc patients.For SSc patients with pulmonary fibrosis,extensive skin involvement,high C3 level might have poor QoL.
ABSTRACT
Hemorrhagic transformation (HT) is a common complication of ischemic stroke, especially after thrombolytic therapy, which is associated with increased morbidity and mortality. Thrombolysis with tissue plasminogen activator (t-PA) increases the rate of HT by as much as 10-fold, and the mortality by about 60%. The patients who are eligible for t-PA treatment are still between 3.4% and 5.2% of all patients with acute ischemic stroke because of the narrow therapeutic time window. Due to the unknown mechanism and therapeutic target of HT, there are no effective drugs to decrease the incidence of HT. The main mechanism of HT is disruption of the blood-brain barrier (BBB) integrity and neurovascular homeostasis, involving a variety of molecular signaling pathways. In animal and clinical studies, combining therapeutic agents with t-PA, which may help to minimize BBB perturbations, reduces the incidence of HT and increases the safety of thrombolytic therapy. This article is prepared to review the mechanisms, targets and therapeutic drugs of t-PA induced HT in recent years to provide a reference to the basic research and drug development of HT.
ABSTRACT
Whether habit stimulation is effective in DOC patient arousal has not been reported. In this paper, we analyzed the responses of DOC patients to habit stimulation. Nineteen DOC patients with alcohol consumption or smoking habits were recruited and 64-channel EEG signals were acquired both at the resting state and at three stimulation states. Wavelet transformation and nonlinear dynamics were used to extract the features of EEG signals and four brain lobes were selected to investigate the degree of EEG response to habit stimulation. Results showed that the highest degree of EEG response was from the call-name stimulation, followed by habit and music stimulations. Significant differences in EEG wavelet energy and response coefficient were found both between habit and music stimulation, and between habit and call-name stimulation. These findings prove that habit stimulation induces relatively more intense EEG responses in DOC patients than music stimulation, suggesting that it may be a relevant additional method for eliciting patient arousal.

AIM: To evaluate the effects of 23G vs 20G pars plana vitrectomy ( PPV ) combined with internal limiting membrane peeling, phacoemulsification and intraocular lens implantation for macular epiretinal membrane with cataract. ·METHODS: Totally 45 eyes of 45 patients with macular epiretinal membrane and cataract were enrolled in this retrospective non-randomized controlled clinical study. All eyes were treated with PPV combined with internal limiting membrane peeling, phacoemulsification and intraocular lens implantation. There were 20 eyes in 23G PPV group, and 25 eyes in 20G PPV group. The best corrected visual acuity ( BCVA ) , intraocular pressure (IOP), counting of corneal endothelial cells ( CEC) and central retinal thickness ( CRT ) were examined before surgery. BCVA results were converted to the logarithm of the minimum angle of resolution ( LogMAR ) visual acuity. All operations were performed by the same doctor. Operation time for vitrectomy and membrane peeling, average ultrasound energy ( AVE) and effective phacoemulsification time ( EPT ) were recorded. BCVA and CRT were observed postoperatively at 30d and 90d, counting of CEC was observed postoperatively at 90d. IOP was observed postoperatively at 1d and 7d. ·RESULTS:The mean operation time for vitrectomy were 12. 57± 1. 35min in 23G group and 17. 30 ± 1. 19min in 20G group. The difference was statistically significant ( t =-12. 488, P<0. 01). There were no statistical significances in operation time for membrane peeling, AVE and EPT between 23G and 20G groups ( t=-0. 68,-1. 186,-0. 737, P=0. 500, 0. 242,0. 465). On 1d after surgery, IOP in 23G group was lower than that in 20G group, the difference was statistically significant (t= -2. 345, P=0. 024). The BCVA and CRT of the two groups both improved after operations. There were no statistically significant differences between two groups in terms of IOP, BCVA, and CRT ( F = 0. 465, 1. 895, 0. 689; P = 0. 499, 0. 176, 0. 411). IOP, BCVA and CRT were significant statistical different in different time-point within each group ( F=291. 245, 103. 06, 665. 402, P<0. 01 ). Different surgical methods of 23G and 20G had interactive effects on IOP with different time points ( F = 13. 245, P<0. 01 ), but different surgeries had no interactive effects on BCVA and CRT with different time points (F=1. 212, 2. 293;P=0. 283, 0. 129). The counting CEC in 23G group was more than that in 20G group postoperatively at 90d, the difference was statistically significant (t=2. 049, P=0. 048). ·CONCLUSION: The 23G PPV combined with internal limiting membrane peeling, phacoemulsification, intraocular lens implantation for macular epiretinal membrane with cataract is effective. Compared with 20G PPV, 23G PPV has advantages in operation time for vitrectomy and counting CEC. But lower IOP is likely in 23G PPV on 1d after surgery
ABSTRACT
Objective To access the toxicity of forsythin from Forsythia suspensa leaves and evaluate its safety. Methods Acute toxicity was determined by oral administration of a single dose of 18 100 mg/kg forsythin in NIH mice. Sub-chronic toxicity was evaluated by oral administration of several doses of forsythin for 30 days at does of 0, 540, 1 620, and 6 480 mg/kg in SD rats. Results In the acute toxicity study, mortality was not observed after 14 days. In addition, clinically relevant adverse effects, or variations in body weight or food consumption were not observed. Similarly, after 30 days in the sub-chronic toxicity study, no mortality or significant toxicological effects such as decreased food consumption, body weight, biochemical parameters and vital organs etc. were noticed. Conclusion The results revealed that the forsythin from Forsythia suspensa leaves has low or no toxicity via oral administration, and therefore is suitable for further development and applications.
ABSTRACT
Objective To analyze the expression of interleukin ( IL)-17A in a mouse model of bleomycin ( BLM)-induced systemic sclerosis ( SSc) and to evaluate its effects on inflammation and fibrosis in skin and lung tissues. Methods Twenty-four female BALB/c mice were randomly divided into four groups:normal control group ( mice were subcutaneously injected with phosphate buffer ) , model group (subcutaneously injected with BLM), antibody group (injected with BLM + IL-17A monoclonal antibody), homotypic control group ( injected with BLM + isotype control) . Pathological changes in skin and lung tis-sues of those mice were observed;inflammatory and fibrotic scores were assessed. Immunohistochemistry and real-time fluorescent quantitative PCR ( RT-PCR) were used to detect the expression of IL-17A, TGF-β1 and typeⅠ collagen in skin and lung tissues of those mice at mRNA level. Mouse lung fibroblasts ( FB) de-rived from the mice of model group were cultured in vitro and then were cultured with IL-17A cytokines with or without the interference of monoclonal antibodies. Expression of typeⅠ collagen and TGF-β1 at mRNA level and levels of IL-6 and TGF-β1 in the culture supernatants were detected by RT-PCR and enzyme-linkedimmunosorbent assay ( ELISA) , respectively. Results Compared with the mice of model and homotypic control groups, those of the antibody group showed mild skin thickening, skin inflammation and lung inflam-mation as well as lower fibrosis scores (P<0. 05). The expression of IL-17A at both protein and mRNA lev-els and the expression of TGF-β1 and collagen typeⅠat mRNA level in skin and lung tissues of mice of the antibody group were significantly lower than those of the model and homotypic control group (P<0. 05). Re-sults of the in vitro cell culture of SSc mice-derived lung FB with IL-17A showed that the expression of TGF-β1 and typeⅠ collagen at mRNA level and the levels of IL-6 and TGF-β1 in the culture supernatants were decreased with the interference of anti-IL-17A monoclonal antibody (P<0. 05), but were still higher than those of the control group (P<0. 05). Conclusion IL-17A promotes the development of inflammation and fibrosis in skin and lung tissues in the mouse model of SSc. Blocking IL-17A might inhibit fibrosis in SSc by inhibiting the production of TGF-β1, IL-6 and typeⅠ collagen.
