Effect of Elevated Basal LH on IVF-ET Outcomes in Patients with Polycystic Ovary Syndrome / 中山大学学报(医学科学版)

ObjectiveTo compare the outcomes in controlled ovarian stimulation （COH） and fresh embryo transfer between women with and those without a high basal luteinizing hormone （bLH） level in polycystic ovary syndrome （PCOS）. MethodsThe clinical data of PCOS patients at the Reproductive Medicine Center of the Sixth Hospital of Sun Yat-sen University from January 2015 to December 2021 were retrospectively analyzed. They were divided into the high group （LH≥10 U/L） and normal group （LH<10 U/L） according to the bLH levels. The results of COH and pregnancy outcomes after fresh transfer were compared， including gonadotropin （Gn） initiation dose， Gn duration， total Gn dose， number of oocytes obtained， two pronuclei （2PN） rate， available embryos rate， high-quality embryos rate， blastocyst formation rate， human chorionic gonadotrophin （HCG） positive rate， clinical pregnancy rate （CPR）， spontaneous abortion rate （SAR）， ongoing pregnancy rate （OPR） and live birth rate （LBR）. The differences in hormonal trends during COH were also analyzed. ResultsThere were no statistically significant differences in age， body mass index， anti-Mullerian hormone， and type of infertility between the two groups. Compared with the normal group， the Gn initiation dose and Gn duration were not statistically significant （P>0.05）， while the total Gn dose was significantly lower （P<0.001） in the high group. The number of oocytes retrieved， 2PN rate， available embryos rate， high-quality embryos rate， and blastocyst formation rate were comparable between the two groups （all P>0.05）. After fresh embryo transfer， they had similar pregnancy outcomes in the HCG positive rate， CPR， SAR， OPR and LBR （all P > 0.05）. ConclusionsIn patients with PCOS， high bLH levels do not affect COH or pregnancy outcomes in fresh transfer cycles. Further studies are needed to determine whether LH levels need to be lowered prior to COH and whether frozen-all strategy is required in patients with elevated bLH levels.

The short-term outcomes of non-contact low frequency ultrasonic debridement in treating periprosthetic joint infections:a prospective single-arm clinical study / 中华外科杂志

Objective: To evaluate the short-term outcomes of non-contact low-frequency ultrasonic debridement in treating periprosthetic joint infections(PJI). Methods: The clinical data of patients with PJI who met the eligibility criteria and were treated with non-contact low-frequency ultrasonic debridement from August 2021 to January 2022 at the Department of Orthopaedics,the First Affiliated Hospital of Xinjiang Medical University were prospectively analyzed. PJI was defined according to the modified Musculoskeletal Infection Society criteria in 2016. After mechanical debridement,an 8-mm handheld non-contact low-frequency ultrasound probe was used for ultrasonic debridement in the whole surgical area at a frequency of (25±5)kHz and power of 90% for 5 minutes. Each ultrasound lasted 10 seconds with 3-second intervals. The probe was repeatedly sonicated among all soft tissue,bone interface and metal prosthesis surface(patients underwent debridement,antibiotics and implant retention (DAIR)) in the surgical area. The femoral canal of the hip joint,the distal femoral canal and the posterior capsule of the knee were fully sonicated with a special right-angle probe. Before and after ultrasonic debridement,20 ml of liquid was extracted from each operation area and injected into aerobic and anaerobic culture bottles,respectively,for pathogen culture. Harris hip score and Hospital for Special Surgery (HSS) score were used to evaluate clinical function. Treatment failure was defined as the recurrence of infection in the same joint. The patients were routinely followed up in the outpatient clinic at 1,3,and 6 months postoperatively and then annually with a deadline of August 2022. The paired t-test,rank sum,Mann-Whitney U or χ2 test was used to compare the observed data,and rates among multiple groups were compared using the Bonferroni approach. Results: A total of 45 patients were included in the study,including 21 men and 24 women with age of (65.8±15.2)years(range: 20 to 80 years) and body mass index of (29.3±4.2)kg/m2(range: 20.2 to 38.5 kg/m2). Twenty-eight patients (18 hips and 10 knees) underwent one-stage revision,and 17 cases (5 hips and 12 knees) underwent DAIR. Three of the patients (6.7%) had recurrent infections during follow-up. There were no intraoperative complications related to ultrasonic debridement (neurovascular and muscle injury,poor wound healing and fat liquefaction). Seventeen patients who received DAIR were followed for a median(M(IQR)) of 9(3) months,and two relapsed 3 weeks and 3 months post-operation,respectively. In addition,28 patients who underwent one-stage revision were followed for a median of 9(2) months,and one of the patients (3.6%,1/28) had a recurrence 6 months post-operation. The culture-positive rate of preoperative aspiration was 47.6% (20/42). The data of intraoperative soft tissue culture was 86.7% (39/45). The culture-positive rate of wound liquid before ultrasonic debridement was 46.7% (21/45). And the culture-positive rate after ultrasonic debridement was (75.6% (34/45)). After sonication,the culture-positive rate of explanted prostheses was 88.9% (40/45). There was a significant difference in culture-positive rates among all five cultures (χ2=35.483,P<0.01). Further pairwise comparison showed that the culture-positive rate of wound liquid after ultrasonic debridement was higher than that before ultrasonic debridement (χ2=7.901,P=0.005) but was not significantly different from the positive rates of other cultures (all P>0.05). The median number of colonies 24 hours after ultrasonic debridement(2 240 (1 310) CFU/ml,range: 310 to 3 140 CFU/ml) was significantly higher than that before debridement(450 (550) CFU/ml,range: 10 to 910 CFU/ml) (U=43, P=0.017). The post-operative Harris ((78.6±4.2)points,range:70.5 to 85.3 points) and HSS scores((76.4±4.8)points,range: 68.5 to 84.3 points) were significantly higher than the preoperative scores((46.0±9.8)points,range: 27.5 to 64.3 points;and (45.5±10.3)points,range: 27.6 to 63.1 points) (t=-14.6,t=-12.7;both P<0.01). Conclusions: Non-contact low-frequency ultrasonic debridement can increase the culture-positive rate and lead to a favorable short-term outcome. In addition,no complications are associated with using this new technique to treat PJI.

Microbial transformation of artemisinin and its derivatives / 中国中药杂志

Microbial transformation is an efficient enzymatic approach for the structural modification of exogenous compounds to obtain derivatives. Compared with traditional chemical synthesis, the microbial transformation has in fact the undoubtable advantages of strong region-and stereo-selectivity, and a low environmental and economic impact on the production process, which can achieve the reactions challenging to chemical synthesis. Because microbes are equipped with a broad-spectrum of enzymes and therefore can metabolize various substrates, they are not only a significant route for obtaining novel active derivatives, but also an effective tool for mimicking mammal metabolism in vitro. Artemisinin, a sesquiterpene with a peroxy-bridged structure serving as the main active functional group, is a famous antimalarial agent discovered from Artemisia annua L. Some sesquiterpenoids, such as dihydroartemisinin, artemether, and arteether, have been developed on the basis of artemisinin, which have been successfully marketed and become the first-line antimalarial drugs recommended by WHO. As revealed by pharmacological studies, artemisinin and its derivatives have exhibited extensive biological activities, including antimalarial, antitumor, antiviral, anti-inflammatory, and immunomodulatory. As an efficient approach for structural modification, microbial transformation of artemisinin and its derivatives is an increasingly popular strategy that attracts considerable attention recently, and numerous novel derivatives have been discovered. Herein, this paper reviewed the microbial transformation of artemisinin and its artemisinin, including microbial strains, culture conditions, product isolation and yield, and biological activities, and summarized the advances in microbial transformation in obtaining active derivatives of artemisinin and the simulation of in vivo metabolism of drugs.

Effective fraction from Simiao Wan prevents hepatic insulin resistant by inhibition of lipolysis via AMPK activation / 中国天然药物

Simiao Wan (SMW) is a traditional Chinese formula, including Atractylodis Rhizoma, Achyranthis Bidentatae Radix, Phellodendri Chinensis Cortex and Coicis Semen at the ratio of 1:1:2:2. It can be used to the treatment of diabetes. However, its bioactive compounds and underlying mechanism are unclear. This study aimed to screen the antilipolytic fraction from SMW and investigate its therapeutic mechanisms on hepatic insulin resistance. Different fractions of SMW were prepared by membrane separation combined with macroporous resin and their antilipolytic activities were screened in fasted mice. The effects of 60% ethanol elution (ESMW) on lipolysis were investigated in 3T3-L1 adipocytes stimulated by palmitic acid (PA) and high fat diet (HFD)-fed mice. In our study, ESMW is the bioactive fraction responsible for the antilipolytic activity of SMW and 13 compounds were characterized from ESMW by UHPLC-QTOF-MS/MS. ESMW suppressed protein kinase A (PKA)-hormone-sensitive lipase (HSL) related lipolysis and increased AMP-activated protein kinase (AMPK) phosphorylation in PA challenged 3T3-L1 adipocytes. AMPKα knockdown abolished the inhibitory effects of ESMW on IL-6 and HSL pSer-660, revealing that the antilipolytic and anti-inflammatory activities of ESMW are AMPK dependent. Furthermore, ESMW ameliorated insulin resistance and suppressed lipolysis in HFD-fed mice. It inhibited diacylglycerol accumulation in the liver and inhibited hepatic gluconeogenesis. Conditional medium collected from ESMW-treated 3T3-L1 cells ameliorated insulin action on hepatic gluconeogenesis in liver cells, demonstrating the antilipolytic activity contributed to ESMW beneficial effects on hepatic glucose production. In conclusion, ESMW, as the antilipolytic fraction of SMW, inhibited PKA-HSL related lipolysis by activating AMPK, thus inhibiting diacylglycerol (DAG) accumulation in the liver and thereby improving insulin resistance and hepatic gluconeogenesis.

Screening of the ubiquitin-proteasome system activators for anti-Alzheimer's disease by the high-content fluorescence imaging system / 中国天然药物

Ubiquitin-proteasome system (UPS) plays an important role in neurodegenerative diseases, such as Alzheimer's disease (AD), Parkinson's disease (PD), and Huntington's disease (HD). The discovery of UPS activators for anti-neurodegenerative diseases is becoming increasingly important. In this study, we aimed to identify potential UPS activators using the high-throughput screening method with the high-content fluorescence imaging system and validate the neuroprotective effect in the cell models of AD. At first, stable YFP-CL1 HT22 cells were successfully constructed by transfecting the YFP-CL1 plasmid into HT22 cells, together with G418 screening. The degradation activity of the test compounds via UPS was monitored by detecting the YFP fluorescence intensity reflected by the ubiquitin-proteasome degradation signal CL1. By employing the high-content fluorescence imaging system, together with stable YFP-CL1 HT22 cells, the UPS activators were successfully screened from our established TCM library. The representative images were captured and analyzed, and quantification of the YFP fluorescence intensity was performed by flow cytometry. Then, the neuroprotective effect of the UPS activators was investigated in pEGFP-N1-APP (APP), pRK5-EGFP-Tau P301L (Tau P301L), or pRK5-EGFP-Tau (Tau) transiently transfected HT22 cells using fluorescence imaging, flow cytometry, and Western blot. In conclusion, our study established a high-content fluorescence imaging system coupled with stable YFP-CL1 HT22 cells for the high-throughput screening of the UPS activators. Three compounds, namely salvianolic acid A (SAA), salvianolic acid B (SAB), and ellagic acid (EA), were identified to significantly decrease YFP fluorescence intensity, which suggested that these three compounds are UPS activators. The identified UPS activators were demonstrated to clear AD-related proteins, including APP, Tau, and Tau P301L. Therefore, these findings provide a novel insight into the discovery and development of anti-AD drugs.

Objective:To investigate the renoprotective effects that Sanjiao Qushi prescription ameliorates cationic bovine serum albumin （C-BSA） induced membranous nephropathy（MN） in mice model and its influence on nuclear factor erythroid-2-related factor-2（Nrf2）/heme oxygenase-1（HO-1） signaling pathway. Method:Sixty female BALB/c mice were randomly divided into the normal group（<italic>n</italic>=10） and the model group（<italic>n</italic>=50）. The mice in the model group received C-BSA injection via tail vein （6.5 mg·kg^-1）. The mice that were successfully modeled were randomized into the model group， the low dose Sanjiao Qushi prescription group（3.71 g·kg^-1）， the high dose Sanjiao Qushi prescription group（7.42 g·kg^-1） and benazepril hydrochloride group（1.3 mg·kg^-1）. And they were administered with the corresponding medicine by gavage once a day for four consecutive weeks. 24 hour-urine protein quantitation were performed before C-BSA injection and after C-BSA injection as well as the medicine gavage. When the treatment was finished， all of the mice were sacrificed and the biochemical indicators such as serum creatinine（SCr）， blood urea nitrogen（BUN）， triglyceride（TG）， total cholesterol（TC）， total protein（TP） and albumin（Alb） were measured. And the renal pathological morphology changes were observed by light microscope with hematoxylineosin（HE）， Masson and periodic acid-silver metheramine（PASM） staining. The deposition of immunoglobulin G（IgG） in the glomerulus was detected by fluorescence microscope. The expression of reactive oxygen species （ROS） of kidney was detected by fluorescence immunoassay. The protein expression levels of Nrf2 in cell nucleus and cytoplasm and the downstream protein factors HO-1 and NADH quinone acceptor oxidoreductase 1（NQO1） were detected by Western blot. Result:Compare to normal group， the levels of 24 hour-urine protein quantitation， TG and TC significantly increased in model group（<italic>P</italic><0.01）， while TP and Alb levels significantly decreased（<italic>P</italic><0.01）. The model group exhibited enlarged volume of glomerular， significantly thickened glomerular basement membrane（GBM）， fuchsinophilic protein deposition and spike formation through light microscope. Immunofluorescence staining for the model group exhibited granular deposition of IgG along the capillary wall. The expression of ROS in kidney significantly increased（<italic>P</italic><0.01）. The protein expression levels of Nrf2 in cell nucleus significantly increased（<italic>P</italic><0.01）， while Nrf2 in cytoplasm significantly decreased（<italic>P</italic><0.01）.The protein expression levels of HO-1 and NQO1 significantly increased（<italic>P</italic><0.01）. Compared to model group， the levels of 24 hour-urine protein quantitation， TG and TC significantly decreased in each treated group（<italic>P</italic><0.01）， TP and Alb levels significantly increased（<italic>P</italic><0.05，<italic>P</italic><0.01）. The pathological damages alleviated obviously. The expression of ROS in kidney significantly decreased（<italic>P</italic><0.01）. The protein expression levels of Nrf2 in cell nucleus significantly decreased（<italic>P</italic><0.01）， while Nrf2 in cytoplasm significantly increased（<italic>P</italic><0.05，<italic>P</italic><0.01）. The protein expression levels of HO-1 and NQO1 significantly increased（<italic>P</italic><0.01）. Conclusion:Sanjiao Qushi prescription worked on MN mice possibly by regulating related proteins in the Nrf2/HO-1 signaling pathway and relieving oxidative stress， thus decreasing 24 hour-urine protein and blood lipid， increasing serum protein， and alleviating the pathological damages to protect renal function and delay progress of the disease.

Effects of propofol and sevoflurane on intestinal flora diversity in infants undergoing cochlear implantation / 医学研究生学报

ObjectiveThe correlation of intestinal flora diversity in infants undergoing cochlear implantation (CI) with different general anesthetics remains unclear. The aim of this study was to observe the effects of propofol and sevoflurane on intestinal flora diversity in infants undergoing cochlear implantation.MethodsFrom January 2018 to August 2018, twenty infants with hearing impairment who underwent CI in the Department of Anesthesiology, Ninth People's Hospital, Shanghai Jiaotong University School of Medicine were randomly divided into propofol group (10 cases) and sevoflurane group (10 cases). The propofol group (group P) received intravenous injection while the sevoflurane group (group S) received inhalation. Genomic DNA was extracted for PCR and 16S rDNA sequencing technique was used to analyze the diversity of intestinal flora (intestinal flora taxonomic composition, flora alpha diversity index, and intestinal flora PICRUSt function prediction).ResultsThe analysis of intestinal flora taxonomic composition showed that the intestinal flora of infants in the two groups were mainly Firmicutes and Bacteroidetes after operation. There was no significant difference in species diversity of intestinal flora (Actinobacteria, Bacteriodetes, Firmicutes, etc.) between Group S and Group P（P＞0.05）. The analysis of flora alpha diversity index showed that there was no significant difference in metrics (species information index, chaol index, Shannon index, etc.) between Group S and Group P（P＞0.05）. The analysis of intestinal flora PICRUSt function prediction showed that there were significant differences in Peptidase metabolism (1.82±0.08, 1.91±0.07, P=0.02), Protein Kinase metabolism (0.32±0.03, 0.28±0.03, P=0.02) and Tuberculosis pathway (0.14±0.01,0.15±0.01,P=0.049) between Group S and Group P after operation.ConclusionSevoflurane and propofol can regulate the functional diversity of intestinal flora through affecting different metabolic pathways of KO function in the functional diversity of intestinal flora and provide new guidance for the use of clinical anesthetics in infants undergoing CI.

Objective:To study the clinical characteristics, diagnosis, treatment and rehabilitation of auditory agnosia after stroke. Methods:Four stroke inpatients with auditory agnosia as the first symptom from January, 2016 to August, 2018 were reviewed. Results:All the patients started with auditory impairment, followed with motor dysfunction and speech impairment. They had a previous history of cerebrovascular disease once or more, and were finally diagnosed as auditory agnosia after stroke. After comprehensive rehabilitation treatment, all the patients could walk independently, and the activities of daily living were improved. Some patients could discriminate environmental sound, but still were poor in listening comprehension. Conclusion:Post-stroke auditory agnosia is rare, with poor outcome, which needs comprehensive assessment, speech perception training and non-verbal communication training to improve the communication.

Malformation of Wharton′s duct with multiple sialoliths: a case report and literature review / 口腔疾病防治

Objective@#To explore the diagnosis and treatment of ductal malformations of the submandibular gland with multiple stones.@*Methods@# A case of a malformation of Wharton′s duct with multiple sialoliths according to the clinical data, diagnosis and treatment of the patient was analyzed retrospectively.@*Results@#The patient′s physical examination and CBCT showed a tumor on the left floor of the mouth. In this case, it was found that the mass was a malformation of Wharton′s duct with multiple sialoliths according to operative exploration. The postoperative pathological examination showed (left submaxillary) salivation gland tissue, duct dilation and duct epithelia hyperplasia, duct calculus, and a large number of lymphocytes proliferating around the duct; 1 month after the follow-up, the patient had healed well. Through literature review and analysis, it was found that cases of submandibular ductal malformation with multiple stones were rare and should be carefully differentiated from arteriovenous malformation at the base of the mouth. Calculi of the submandibular gland can be removed by incision through the oral submandibular duct or by combined resection of the submandibular gland and ductal calculi, and some smaller calculi can also be treated by endoscopy of the salivary gland. @* Conclusion@# In cases of submandibular ductal malformation with multiple stones, intraoral and extraoral incisions should be performed simultaneously to remove the associated ductal stones.

Low expression of SNHG3 was in negative correlation to Ki-67 (rs=-0.296, P=0.013).ConclusionThe expression of SNHG3 downregulated in breast cancer tissues, and its expression level is related to Ki-67, which may serve as a potential diagnostic molecular marker.

Specific Th2 immune response of MUC1 induced by thmosin α1 / 吉林大学学报(医学版)

Objective:To investigate the MUC1 specific immune response enhanced by thmosinα1(Tα1)using MUC1-MBP as the specific antigen,and to discuss the feasibility of MUC1-MBP as an adjuvant.Methods:The C57BL/6 mice were randomly divided into normal saline group,MUC1-MBP+BCG group and MUC1-MBP+Tα1 group.The T cellular immune activities,MUC1 special antibody and subclass,anti-tumor effect of Tα1 combined with MUC1-MBP were detected.4-7 d after the 3rd immunization,the spleen indexes of the mice in various groups were measured;the lymphocyte proliferation response was used to detect the stimulate index(SI)of the mice in various groups;the levels of specific cytokines IFN-γ,IL-2,IL-4 and IL-10 in the supernatant of spleen cells of the mice were detected by ELISA;the level of serum MUC1-specific antibody was detected by ELISA.The C57BL/6 mice were inoculated with B16-MUC1 7 d after the last immunization and the survival of the mice was observed.Results:Compared with normal saline group,the spleen index and SI of the mice in MUC1-MBP+Tα1 and MUC1-MBP+BCG groups were significantly increased(P< 0.05 or P<0.01);the specific SI of MUC1 were significantly increased(P< 0.05).Compared with normal saline group,the levels of IFN-γ and IL-2 in the supernatant of spleen cells of the mice in MUC1-MBP+BCG group were obviously increased(P<0.05);the levels of IL-4 and IL-10 were slightly increased,but there were no significant differences(P>0.05);compared with normal saline group,the level of IL-4 in MUC1-MBP+Tα1 group was obviously increased(P< 0.01);the levels of IFN-γ,IL-2 and IL-10 were slightly increased,but there were no significant differences(P>0.05).The titer of MUC1 specific antibody was increased with the increase of concentration of Tα1.The antibody subtype detection results showed that compared with normal saline group,the level of IgG1 in MUC1-MBP+BCG group was significantly increased(P< 0.05 or P< 0.01),and the level of IgG2a had no obvious change.The tumor prevention experiment results showed that compared with normal saline group,the survival rates of the mice in MUC1-MBP+BCG group and MUC1-MBP+Tα1 group had no significant differences.Conclusion:MUC1-MBP combined with Tα1 prefers to Th2 immune responses in the mice.It indicates that Tα1 can be used as an adjuvanted preventive vaccines,but not suitable for therapeutic vaccines.

Intrafollicular Soluble RAGE Benefits Embryo Development and Predicts Clinical Pregnancy in Infertile Patients of Advanced Maternal Age Undergoing In Vitro Fertilization / 华中科技大学学报（医学）（英德文版）

Soluble receptor for advanced glycation end products (sRAGE) can decoy the toxic AGEs and is considered to be a protective factor.This study aimed to evaluate the correlation between intrafollicular sRAGE levels and clinical outcomes in infertile women of young or advanced maternal age (AMA) undergoing in vitro fertilization (IVF).A total of 62 young women and 62 AMA women who would undergo IVF were included in this prospective study.The intrafollicular sRAGE concentration was measured to determine its association with the number of retrieved oocytes,fertilized oocytes,high-quality embryos or achievement of clinical pregnancy in young and AMA women,respectively.Besides,correlations between sRAGE and age or follicle-stimulating hormone (FSH) were examined.We found that the intrafollicular sRAGE levels were higher in young patients than those in AMA patients,suggesting that the sRAGE levels were inversely correlated with age.In young patients,sRAGE showed no correlation with the number of retrieved oocytes,fertilized oocytes,high-quality embryos or achievement of clinical pregnancy.But it was found that AMA patients with more retrieved oocytes,fertilized oocytes and high-quality embryos demonstrated higher sRAGE levels,which were a prognostic factor for getting clinical pregnancy independent of age or FSH level.In conclusion,the sRAGE levels decrease with age.Elevated intrafollicular sRAGE levels indicate good follicular growth,fertilization and embryonic development,and successful clinical pregnancy in AMA women,while in young women,the role of sRAGE may not be so predominant.

Inductive effect of recombinant MUC1-MBP fusion protein combined with R848 on immune activity of T cells in mice / 吉林大学学报(医学版)

Objective:To study the inductive effect of recombinant MUC1-MBP fusion protein combined with R848 on the immune activity of T cells in the mice,and to provide experimental basis for searching the suitable adjuvants of recombinant MUC1-MBP fusion protein.Methods:A total of 21 C57BL/6 mice were randomly divided into control group(treat with normal saline),MUC1-MBP+R848 group (treated with MUC1-MBP+R848),and MUC1-MBP+baillus calmette guerin(BCG) group(treated with MUC1-MBP+BCG)(n=7).After immunized for 4-7 d,the spleen tissue was taken and the spleen indexes of the mice in various groups were measured;the stimmulus index(SI) of the mice was detected by lymphocyte proliferation response;the levels of tumor necrosis factor-γ(TNF-γ) and interleukin-4(IL-4) were detected by ELISA method;the proprotions of T lymphocyte subsets in spleen cells were analyzed by flow cytometry.Results:Compared with control group,the spleen indexes,SI,and TNF-γ levels of the mice in MUC1-MBP+ R848 and MUC1-MBP+BCG groups were significantly increased (P0.05).Compared with control group,the proprotions of CD3+T,CD4+T,and CD8+ T cells of the mice in MUC1-MBP+ R848 group and MUC1-MBP+BCG group were significantly increased(P<0.05 or P<0.01).Conclusion:Both MUC1-MBP fusion protein combined with R848 and BCG can induce the Th1 type of immune activity in the mice,and R848 is the potential candidate adjuvant for MUC1-MBP.
