The Solanaceae plants distributed in China belong to 105 species and 35 varietas of 24 genera. Some medicinal plants of Solanaceae are rich in tropane alkaloids(TAs), which have significant pharmacological activities. In this paper, the geographical distribution, chemical components, traditional therapeutic effect, pharmacological activities, and biosynthetic pathways of TAs in Solanaceous plants were summarized. Besides, the phylogeny of medicinal plants belonging to Solanaceae was visualized by network diagram. Fourteen genera of Solanaceae plants in China contain TAs and have medical records. TAs mainly exist in Datura, Anisodus, Atropa, Physochlaina, and Hyoscyamus. The TAs-containing species were mainly concentrated in Southwest China, and the content of TAs was closely related to plant distribution area and altitude. The Solanaceae plants containing TAs mainly have antispasmodic, analgesic, antiasthmatic, and antitussive effects. Modern pharmacological studies have proved the central sedative, pupil dilating, glandular secretion-inhibiting, and anti-asthma activities of TAs. These pharmacological activities provide a reasonable explanation for the traditional therapeutic efficacy of tropane drugs. In this paper, the geographical distribution, chemical components, traditional therapeutic effect, and modern pharmacological activities of TAs-containing species in Solanaceae were analyzed for the first time. Based on these data, the genetic relationship of TAs-containing Solanaceae species was preliminarily discussed, which provided a scientific basis for the basic research on TAs-containing solanaceous species and was of great significance for the development of natural medicinal plant resources containing TAs.

Objective: To compare the efficacy between laparoscopic and open proximal gastrectomy with double-tract reconstruction for Siewert type II and III adenocarcinoma of the esophagogastric junction (AEG). Methods: A retrospective cohort study was conducted. Inclusion criteria: (1) 18 to 80 years old; (2) Siewert II and III AEG was confirmed by preoperative gastroscopy and biopsy, which could not be resected by endoscopy; patients undergoing radical proximal gastrectomy with double-tract reconstruction; (3) contrast-enhanced abdominal CT staging was cT1-2N0M0; (4) Eastern Cooperative Oncology Group (ECOG) physical status score <2 points, American Association of Anesthesiologists (ASA) grade 1 to 2; (5) patients agreed to perform proximal gastrectomy and signed an informed consent. Those who had undergone neoadjuvant radiochemotherapy, suffered from serious mental diseases and had incomplete data were excluded. According to the above criteria, clinical data of 84 consecutive patients with Siewert II and III AEG undergoing surgery at General Surgery Department of The Affiliated Tumor Hospital of Zhengzhou University from October 2010 to December 2018 were collected and analyzed. Of 84 patients, 61 underwent open proximal gastrectomy with double-tract reconstruction (OPG group), while 23 underwent laparoscopic proximal gastrectomy with double-tract reconstruction (LPG group). The perioperative complications and postoperative reflux esophagitis of two groups were compared. A P-value of <0.05 was considered to be statistically significant. Results: Among 84 cases, 74 were male and 10 were female. There were 43 cases of Siewert type II and 41 cases of Siewert type III. There were no significant differences in age, gender, body mass index, comorbidities, Siewert type, and tumor staging between the two groups (all P>0.05). As compared to the OPG group, the LPG group had longer operation duration [(223±21) minutes vs. (161±14) minutes, t=15.352, P<0.001], less intraoperative blood loss [195 (150, 215) ml vs. 208 (192, 230) ml, Z=2.143, P=0.032], and shorter time to flatus [(2.8±0.7) days vs. (3.3±0.9) days, t=2.477, P=0.015]. There were no significant differences in the number of harvested lymph nodes, time to the first meal and postoperative hospital stay between the two groups (all P>0.05). Postoperative complications developed in 2 cases (8.7%, 1 case each for anastomotic leakage and intestinal obstruction) in the LPG group and 5 cases (8.2%, 1 case each for anastomotic leakage, anastomotic bleeding, and anastomotic stenosis, 2 cases of incision infection) in the OPG group (χ(2)=5.603, P=0.231). The median follow-up was 41.2 (12.8-110.5) months. One patient (1.6%,1/61) had obvious reflux symptoms in the OPG group, compared with none in the LPG group (χ(2)=0.644, P=0.422). Esophagitis occurred in 1 case (4.8%, 1/21) in LPG group, compared with 4 patients (7.1%, 4/56) in the OPG group, without significant difference between the two groups (χ(2)=0.505, P=0.477). Conclusion: Laparoscopic proximal gastrectomy with double-tract reconstruction is safe and feasible without increasing the risk of postoperative complication and reflux esophagitis.

Objective To analyze the treatment outcome and related influencing factors of Tibet- an nationality new smear-positive pulmonary tuberculosis patients in Qinghai Province，so as to provide evidence for tuberculosis control and treatment among Tibetan population． Methods Statistical analysis was conducted on 5 564 Tibetan nationality new smear-positive pulmonary tuberculosis cases in Qinghai province who were reported in the China Tuberculosis Information Management System and approved to receive treatment from 2008 to 2017． The main influencing factors were detected by unconditional Logistic regression model analysis，dependent variable was successful treatment or not，independent variables were other factors related to the treatment outcome． Ｒesults The treatment success rate of Tibetan nationality new smear-positive pulmonary tuberculosis cases was 87. 1% ( 4 848 /5 564) ，and the adverse outcome rate was 12. 9% ( 716 /5 564) ． Unconditional Logistic regression model analysis indicated that non-full- course supervision management，living in agricultural and pastoral area，having severe disease，floating population，and age older than 60 years were risk factors of adverse outcome． The odds ratio( OＲ) 95% confidence interval( CI) of the above risk factors were 13. 044( 10. 671-15. 944) ，2. 305( 1. 703-3. 119) ， 2. 090( 1. 346-3. 243) ，1. 967( 1. 443-2. 682) ，and 1. 909( 1. 410-2. 586) ． Clinical consultation，farmers and herdsmen were protective factors． The OＲ( 95% CI) were 0. 451( 0. 375-0. 543) ，and 0. 786( 0. 627- 0. 985) ． Conclusions Treatment success rate of Tibetan nationality new smear positive pulmonary tuberculosis cases was low． Therefore，the directly observed treatment short-course ( DOTS) strategy should be strictly implemented and the full-course supervision management should be strengthened to improve the treatment success rate． More attention should be paid to the elderly，severe，floating，agricultural and pastoral populations among the Tibetan population．

The relationship between areca nut as a primary carcinogen and oral cancer has been widely concerned. Areca can change the levels of reactive oxygen species (ROS) and autophagy in cells, and the levels of ROS and autophagy are closely related to the occurrence and development of tumors. This paper reviewed the relationships among areca nut, intracellular ROS, and autophagy.

Non-obstructive azoospermia (NOA), which is defined as the absence of spermatozoa in the ejaculate secondary to impaired spermatogenesis within the testis, may be caused by a variety of etiologies, including varicocele-induced testicular damage, cryptorchidism, prior testicular torsion, post-pubertal mumps orchitis, gonadotoxic effects from medications, genetic abnormalities, chemotherapy/radiation, and other unknown causes currently classified as idiopathic (Cocuzza et al., 2013). The microdissection testicular sperm extraction (micro-TESE) technique involves a meticulous microsurgical exploration of the testicular parenchyma to identify and selectively extract larger seminiferous tubules that carry a higher probability of complete spermatogenesis (Schlegel, 1999). The Cornell group evaluated the efficacy of micro-TESE in 152 NOA patients with an associated history of cryptorchidism. In their series, spermatozoa were successfully retrieved in 116/181 attempts (64%), and the resulting pregnancy rate was 50% with a delivery rate of 38% (Dabaja and Schlegel, 2013). Franco et al. (2016) described a stepwise micro-TESE approach in NOA patients, which was considered to reduce the cost, time, and effort associated with the surgery. Alrabeeah et al. (2016) further reported that a mini-incision micro-TESE, carried through a 1-cm equatorial testicular incision, can be useful for micro-TESE candidates, particularly in patients with cryptozoospermia. We conducted a retrospective study of 20 consecutive NOA patients with a history of orchidopexy from May 2015 to March 2017.

Objective: To evaluate the outcomes of myelodysplastic syndromes (MDS) patients who received HLA-matched sibling donor allogeneic peripheral blood stem cell transplantation (MSD-PBSCT) . Methods: The clinical data of 138 MDS patients received MSD-PBSCT from Sep. 2005 to Dec. 2017 were retrospectively analyzed, and the overall survival (OS) rate, disease-free survival (DFS) rate, relapse rate (RR) , non-relapse mortality (NRM) rate and the related risk factors were explored. Results: ①After a median follow-up of 1 050 (range 4 to 4 988) days, the 3-year OS and DFS rates were (66.6±4.1) % and (63.3±4.1) %, respectively. The 3-year cumulative incidence of RR and NRM rates were (13.9±0.1) % and (22.2±0.1) %, respectively. ②Univariate analysis showed that patients with grade Ⅲ-Ⅳ acute graft-versus-host disease (aGVHD) or hematopoietic cell transplantation comorbidity index (HCT-CI) ≥2 points or patients in very high-risk group of the Revised International Prognostic Scoring System (IPSS-R) had significantly decreased OS[ (42.9±13.2) %vs (72.9±4.2) %, χ(2)=8.620, P=0.003; (53.3±7.6) %vs (72.6±4.7) %, χ(2)=6.681, P=0.010; (53.8±6.8) %vs (76.6±6.2) %vs (73.3±7.7) %, χ(2)=6.337, P=0.042]. For MDS patients with excess blasts-2 (MDS-EB2) and acute myeloid leukemia patients derived from MDS (MDS-AML) , pre-transplant chemotherapy or hypomethylating agents (HMA) therapy could not improve the OS rate[ (60.4±7.8) %vs (59.2±9.6) %, χ(2)=0.042, P=0.838]. ③Multivariate analysis indicated that the HCT-CI was an independent risk factor for OS and DFS (P=0.012, HR=2.108, 95%CI 1.174-3.785; P=0.008, HR=2.128, 95%CI 1.219-3.712) . Conclusions: HCT-CI was better than the IPSS-R in predicting the outcomes after transplantation. The occurrence of grade Ⅲ-Ⅳ aGVHD is a poor prognostic factor for OS. For patients of MDS-EB2 and MDS-AML, immediate transplantation was recommended instead of receiving pre-transplant chemotherapy or HMA therapy.

Objective: To assess the efficacy and toxicity of decitabine-based conditioning regimen in patients with myelodysplastic syndrome (MDS) , acute myeloid leukemia secondary to MDS (MDS-AML) or chronic myelomonocytic leukemia (CMML) . Methods: From March 1, 2013 to May 25, 2015, 22 patients who underwent allogenic hematopoietic stem cell transplantation (allo-HSCT) with decitabine-based conditioning regimen were analyzed retrospectively. Results: ①22 patients, 14 males and 8 females with a median age of 42.5 (24-56) years old, were diagnosed as MDS (n=14) , CMML (n=4) , MDS-AML (n=4) . ②15 patients were treated with the conditioning regimen of decitabine combined with busulfan, cyclophosphamide, fludarabine, and cytarabine, the other 7 cases were treated with decitabine, busulfan, fludarabine, and cytarabine. The dose of decitabine was 20 mg·m(-2)·d(-1) for 5 days.Rabbit anti-human anti-thymocyte globulin (2.5 mg·kg(-1)·d(-1) for 4 days) was involved in conditioning regimen in patients with unrelated donor or haploidentical transplantation. ③Except 1 patient died of infection in 2 months after transplantation, the other patients were engrafted successfully. The median time of granulocyte engraftment was 13 (12-18) days, and the median time of platelet engraftment was 16 (13-81) days. ④The incidence of acute graft versus host disease (aGVHD) was (41.3±10.6) %, and severe aGVHD (grade of III-IV) was (18.4±9.7) %. The incidence of chronic graft versus host disease (cGVHD) was (56.4±11.3) %, and extensive cGVHD was (36.4±12.1) %. ⑤8 patients were suffered with cytomegalovirus (CMV) viremia. Among the 18 patients with definitely infection, 6 occurred during myelosuppression and 12 cases occurred after hematopoietic reconstruction. The 2-year and 3-year non-relapse mortality was (13.9±7.4) % and (24.3±9.5) %, respectively. ⑥The 2-year and 3-year overall survival (OS) was (77.3±8.9) % and (67.9±10.0) %, respectively. The 2-year and 3-year relapse-free survival (RFS) was (72.7±9.5) % and (63.6±10.3) %, respectively. Conclusions: allo-HSCT with decitabine-based conditioning regimen is feasible in the treatment of MDS, MDS-AML or CMML.

OBJECTIVETo identify the role of serum cytokine levels prior allogeneic hematopoietic stem cell trans-plantation (allo-HSCT) in the outcome of severe aplastic anemia (SAA) patients received allo-HSCT treatment.

METHODSThe clinical data of 117 SAA patients received allo-HSCT were enrolled in this study. The overall survival (OS), graft versus host disease (GVHD) incidence and relationship of serum cytokines with OS and major transplantation complications were retrospectively analyzed.

RESULTSThe patients enrolled in this study included 78(66.7%) cases received HSCT matched sibling donors (MSD), 12(10.2%) HSCT of unrelated donors (MUD) and 27 cases received HSCT of haploidentical donors (HID). The 5-years OS was 76.0%(95% CI: 64.4-87.5%); aGVHD cumulative incidence was 49.6%(95% CI: 40.4%-58.8%) and cumulative incidence cGVHD was 31.6%(95% CI:23.1%-40.2%). MSD allo-HSCT had a significantly higher 5-years OS as compared with the other donors(82.3%±6.6% vs 61.3%±11.7%, P<0.05). HLA matching, donor's age, cytomegalovirus/ Epstein-Barr virus (CMV/EBV) infection were important factors of affecting occurence of aGVHD. The patients with higher serum IL-6 had reduced platelet recovery time after transplantation (14.6±1.8 vs 18.3±2.6 d)(P=0.050) and higher serum TNF-α level accompanied by a lower incidence of CMV/EBV infection (37.8%±11.1% vs 58.8±16.8%)(P<0.05).

CONCLUSIONMSD allo-HSCT is the effective treatment for SAA patients. Donor's type remains the strong predictor of survival. The serum levels IL-6 and TNF-α before transplantation associate with platelet recovery and CMV/EBV infection.

OBJECTIVETo investigate the effects of berberine (BBR) and cinnamic acid (CA), the main active components in Jiaotai Pill (, JTP), on palmitic acid (PA)-induced intracellular triglyceride (TG) accumulation in NIT-1 pancreatic β cells.

METHODSCells were incubated in culture medium containing PA (0.25 mmol/L) for 24 h. Then treatments with BBR (10 μmol/L), CA (100 μmol/L) and the combination of BBR and CA (BBR+CA) were performed respectively. Intracellular lipid accumulation was assessed by Oil Red O staining and TG content was measured by colorimetric assay. The expression of adenosine monophosphate-activated protein kinase (AMPK) protein and its downstream lipogenic and fatty acid oxidation genes, including fatty acid synthase (FAS), acetyl-coA carboxylase (ACC), phosphorylation acetyl-coA carboxylase (pACC), carnitine acyl transferase 1 (CPT-1) and sterol regulating element binding protein 1c (SREBP-1c) were determined by Western blot or real time polymerase chain reaction.

RESULTSPA induced an obvious lipid accumulation and a significant increase in intracellular TG content in NIT-1 cells. PA also induced a remarkable decrease in AMPK protein expression and its downstream targets such as pACC and CPT-1. Meanwhile, AMPK downstream lipogenic genes including SREBP-1c mRNA, FAS and ACC protein expressions were increased. Treatments with BBR and BBR+CA, superior to CA, significantly reversed the above genes changes in NIT-1 pancreatic β cells. However, the synergistic effect of BBR and CA on intracellular TG content was not observed in the present study.

CONCLUSIONIt can be concluded that in vitro, BBR and BBR+CA could inhibit PA-induced lipid accumulation by decreasing lipogenesis and increasing lipid oxidation in NIT-1 pancreatic β cells.

BACKGROUNDUrine output (UO) is an essential criterion of the Kidney Disease Improving Global Outcomes (KDIGO) definition and classification system for acute kidney injury (AKI), of which the diagnostic value has not been extensively studied. We aimed to determine whether AKI based on KDIGO UO criteria (KDIGOUO) could improve the diagnostic and prognostic accuracy, compared with KDIGO serum creatinine criteria (KDIGOSCr).

METHODSWe conducted a secondary analysis of the database of a previous study conducted by China Critical Care Clinical Trial Group (CCCCTG), which was a 2-month prospective cohort study (July 1, 2009 to August 31, 2009) involving 3063 patients in 22 tertiary Intensive Care Units in Mainland of China. AKI was diagnosed and classified separately based on KDIGOUOand KDIGOSCr. Hospital mortality of patients with more severe AKI classification based on KDIGOUOwas compared with other patients by univariate and multivariate regression analyses.

RESULTSThe prevalence of AKI increased from 52.4% based on KDIGOSCrto 55.4% based on KDIGOSCrcombined with KDIGOUO. KDIGOUOalso resulted in an upgrade of AKI classification in 7.3% of patients, representing those with more severe AKI classification based on KDIGOUO. Compared with non-AKI patients or those with maximum AKI classification by KDIGOSCr, those with maximum AKI classification by KDIGOUOhad a significantly higher hospital mortality of 58.4% (odds ratio [OR]: 7.580, 95% confidence interval [CI]: 4.141-13.873, P< 0.001). In a multivariate logistic regression analysis, AKI based on KDIGOUO (OR: 2.891, 95% CI: 1.964-4.254, P< 0.001), but not based on KDIGOSCr (OR: 1.322, 95% CI: 0.902-1.939, P = 0.152), was an independent risk factor for hospital mortality.

CONCLUSIONUO was a criterion with additional value beyond creatinine criterion for AKI diagnosis and classification, which can help identify a group of patients with high risk of death.
