Objective: To explore the clinical features and pregnancy outcomes of intrauterine subchorionic hematoma and retroplacental hematoma. Methods: From May 2016 to May 2018, in the Fourth Hospital of Xi′an City, 110 cases of intrauterine hematoma were selected in the middle of pregnancy, including 52 cases of subchorionic hemaloma (group A) and 58 cases of retroplacental hematoma (group B). The clinical features and pregnancy outcomes of the two groups were compared. Results: The volume of hematoma in group B was significantly smaller than that in group A [(8.8 ± 1.7) cm³ vs. (18.3 ± 2.0) cm³], the gestational weeks of group B was also significantly lower than that of group A [(35.2 ± 2.1) weeks vs. (38.4 ± 1.8) weeks], the full-term pregnancy rate in group B was lower than that in group A[56.9%(33/58) vs. 84.6%(44/52)], miscarriage rate and premature birth rate were higher than those in group A [20.7%(12/58) vs. 5.8%(3/52), 22.4%(13/58) vs. 7.7%(4/52)], and the differences were statistically significant (P < 0.05).The incidence of fetal distress in group B was higher than that in group A [17.4%(8/46) vs. 2.0%(1/49)], the incidence of fetal membrane rupture, placental abnormality, and placental residue was all higher than that in group A[41.3%(19/46) vs.10.2%(5/49), 37.0%(17/46)vs.12.2%(6/49), 28.3%(13/46) vs. 6.1%(3/49)], and the differences were statistically significant (P < 0.05). The neonatal body mass in group B was lower than that in group A [(3 091.7 ± 887.6) g vs. (3 457.6 ± 560.2) g], and the incidence of neonatal diseases was higher than that of group A [15.2%(7/46) vs. 2.0%(1/49)], and the differences were statistically significant (P < 0.05). Conclusions The volume of hematoma and gestational weeks of intrauterine retroplacental hematoma are lower than those of subchorionic hematoma, and the retroplacental hematoma is more likely to have adverse pregnancy outcomes.

OBJECTIVETo explore the effects and mechanisms of multi-glycoside of Tripterygium wilfordii (GTW) on improving glomerular inflammatory lesion in rats with diabetic nephropathy (DN).

METHODDN model was induced by unilateral nephrectomy and intraperitoneal injection of STZ (35 mg x kg(-1)) twice. The rats were randomly divided into 3 groups, the sham-operated group (Sham group, n = 5), the vehicle-given group (Vehicle group, n = 5 ) and GTW-treated group (GTW group, n = 5). After the model was successfully established, the rats in GTW group were daily oral administrated with GTW suspension (50 mg x kg(-1) x d(-1)), meanwhile, the rats in Vehicle group were daily oral administrated with distilled water (2 mL) for 8 weeks. From the beginning of the administration, all rats were killed 8 weeks later. Blood and renal tissues were collected,and then UAlb, renal function, glomerular morphology characteristics and glomerular macrophages (ED1 + cells) infiltration, as well as the protein expressions of inflammatory cytokines including tumor necrosis factor(TNF)-α and interleukin(IL)-lβ, and the key molecules in p38MAPK signaling pathway including p38 mitogenactivated protein kinase (MAPK), phosphorylated p38 (p-p38MAPK) and transforming growth factor(TGF)-β1 were investigated respectively.

RESULTGTW not only ameliorated the general state of health and body weight,but also attenuated UAlb, glomerulosclerosis, the infiltration of glomerular ED1 + cells and the protein expressions of TNF-α, IL-1β, p-p38MAPK and TGF-β1 in the kidney in DN model rats.

CONCLUSIONBy means of DN model rats, we demonstrated that GTW has the protective effect on renal inflammatory damage in vivo via inhibiting inflammatory cells infiltration and inflammatory cytokines expression. Furthermore, GTW could improve renal inflammatory lesion through down-regulating the expressions of the key signaling molecules in p38MAPK pathway such as p-p38MAPK and TGF-β1 ,and inhibiting the activation of p38MAPK signaling in the kidney.

OBJECTIVETo evaluate the effects of mechanical ventilation on pulmonary function during short duration of general anesthesia with tracheal intubation, and assess the safety of controlled spontaneous respiration during general anesthesia.

METHODSFifty-three adult patients (aged 18-55 years, ASA physical status I-II) scheduled for elective unilateral tympanoplasty were randomly assigned into mechanical ventilation group (group M, n=28) and spontaneous respiration group (group S, n=25). Anesthesia induction was performed in group M with intravenous propofol (2 mg/kg), fentanyl (3 microg

RESULTSA total of 43 patients (group M, n=23; group S, n=20) were included in the study with 10 dropouts due to failed attempt to obtain arterial blood samples (8 patients) or severe bucking during intubation (2 patients). No significant differences were found in HR and MAP between the two groups (P>0.05). The pH and SpO(2) [ (97.9-/+1.00)% at the lowest] and PaO(2) in group S were significantly lower and the PaCO(2) was higher than those in group M (P<0.05). In group S, the pH values were 7.274-/+0.025 and 7.331-/+0.039, PaCO(2) values were 60-/+6 and 53-/+5 mmHg, and PETCO(2) values were 53-/+ 6 and 48-/+7 mmHg, and the PaO(2) values were 143-/+37 and 165-/+49 mmHg immediately and 150 min after the intubation, respectively. These values were considered safe under the concept of permissive hypercapnia. No significant differences were found in the P(A-a)DO(2), RI, VD/VT and TFC between or within the two groups (P>0.05), nor were moving, bucking, swallowing and awareness recorded during the surgical procedures.

CONCLUSIONIn essentially normal lungs, short-term mechanical ventilation during general anesthesia with tracheal intubation does not damage the lung functions, and spontaneous respiration can offer sufficient oxygen supply without causing harmful carbon dioxide retention.

Subthalamic nucleus (STN) is the main target nucleus for deep brain stimulation (DBS) treatment in patients with Parkinson disease.To implant the electrode on the sensorimotor part of STN individually and accurately,the boundary of STN is required to be clarified clearly on the magnetic resonance imaging (MRI) without geometric distortion.At present,there are three categories of MRI sequences:spin echo sequence including T2-weighted imaging (T2WI),inversion recovery (IR),diffusion tensor imaging (DTI),and fractional anisotropy (FA);magnetization transfer technique including magnetic susceptibility weighted imaging (SWI) and T2-weighted magnitude imaging (T2 * WI);image reconstruction technique such as quantitative susceptibility mapping (QSM).It is found that QSM can provide optimal signal-noise ratio to identify the boundary of STN,T2 * technique comes second.T2WI has high geometric accuracy when the patients wear frame,which is appropriate for direct DBS implantation on STN with frame.

BACKGROUNDGastrojejunostomy (GJJ) and endoscopic stenting (ES) are palliative treatments for gastric outlet obstruction (GOO) caused by gastric cancer. We compared the outcomes of GJJ with ES by performing a meta-analysis.

METHODSClinical trials that compared GJJ with ES for the treatment of GOO in gastric cancer were included in the meta-analysis. Procedure time, time to resumption of oral intake, duration of hospital stay, patency duration, and overall survival days were compared using weighted mean differences (WMDs). Technical success, clinical success, procedure-related mortality, complications, the rate of re-obstruction, postoperative chemotherapy, and reintervention were compared using odds ratios (OR s).

RESULTSNine studies were included in the analysis. Technical success and clinical success were not significantly different between the ES and GJJ groups. The ES group had a shorter procedure time (WMD = -80.89 min, 95% confidence interval [CI] = -93.99 to -67.78,P < 0.001), faster resumption of oral intake (WMD = -3.45 days, 95% CI = -5.25 to -1.65,P < 0.001), and shorter duration of hospital stay (WMD = -7.67 days, 95% CI = -11.02 to -4.33,P < 0.001). The rate of minor complications was significantly higher in the GJJ group (OR = 0.13, 95% CI = 0.04-0.40,P < 0.001). However, the rates of major complications (OR = 6.91, 95% CI = 3.90-12.25,P < 0.001), re-obstruction (OR= 7.75, 95% CI = 4.06-14.78,P < 0.001), and reintervention (OR= 6.27, 95% CI = 3.36-11.68,P < 0.001) were significantly lower in the GJJ group than that in the ES group. Moreover, GJJ was significantly associated with a longer patency duration (WMD = -167.16 days, 95% CI = -254.01 to -89.31,P < 0.001) and overall survival (WMD = -103.20 days, 95% CI = -161.49 to -44.91, P= 0.001).

CONCLUSIONSBoth GJJ and ES are effective procedures for the treatment of GOO caused by gastric cancer. ES is associated with better short-term outcomes. GJJ is preferable to ES in terms of its lower rate of stent-related complications, re-obstruction, and reintervention. GJJ should be considered a treatment option for patients with a long life expectancy and good performance status.

Objective To explore the relationship between -262C/T and -21A/T polymorphisms of catalase(CAT) gene and coal-burning borne fluorosis. Methods In 2007, 150 villagers were taken as a nonintervention group in Bijie city from the village of coal-burning borne fluorosis areas with unchanged cooking stoves;150 villagers were taken as the intervention group from the town of Changchun county where cooking stoves changed; 150 villagers were taken as control from non-endemic fluorosis areas in Baiyun town of Changshun county.PCR-restriction fragment length polymorphism were employed to detect genotypes of CAT-262C/T and CAT-21A/T polymorphism of CAT gene. Results The genotypic frequencies of CAT-262C/T and CAT-21A/T in nonintervention group,intervention group and control group were in line with Hardy-Weinberg equilibrium law (P＞ 0.05 ).The genotypes of CC and CT were detected while no TT were detected for CAT-262C/T polymorphism; the genotypes of AA, AT and TT were detected for CAT-21A/T. The genotype frequencies of CAT-262 CC, CT in control group, intervention group and non-intervention group were (89.33%(134/150), 10.67%(16/150); 88.67%(133/150), 11.33% (17/150),93.33% (140/150),6.67% (10/150), respectively. The gene frequency of C in control group, intervention group and non-intervention group were (94.67% (284/300), 94.33% (283/300),96.67%(290/300), respectively. The gene frequency of T in control group, intervention group and non-intervention group were 5.33%(16/300), 5.67%(17/300), 3.33%(10/300), respectively. The genotype frequencies of CAT-21 AA,AT and TT in control group, intervention group and non-intervention group were 48.67%(73/150),46.00%(69/150),5.33%(8/150) ,52.67%(79/150) ,38.00%(57/150) ,9.33% (14/150) ,51.33%(77/150) ,38.00%(57/150), 10.67%(16/150), respectively. The gene frequency of A in control group, intervention group and non-intervention group were 71.67%(215/300),71.67%(215/300),70.33%(211/300), respectively. The gene frequency of T in control group, intervention group and non-intervention group were 28.33% (85/300),28.33% (85/300),29.67% (89/300),respectively. CAT-262C/T and CAT-21A/T genotype and allele frequencies in the control group, the intervention group and non-intervention group showed no significant differences in the distribution(x2= 0.331,0.336, all P ＞0.05 ). Conclusion CAT-262C/T and CAT-21A/T polymorphism is not associated with coal-burning borne fluorosis.

Objective To observe the clinical efficacy of warm needling plus Chinese medication for external application in treating post-stroke shoulder pain. Method Two hundred patients with post-stroke shoulder pain were randomized into a treatment group and a control group, 100 cases each. The two groups both received rehabilitation training for shoulder joint. In addition, the treatment group was given warm needling plus Chinese medication for external application, while the control group was given warm needling. Visual Analogue Scale (VAS) for pain, upper-limb Fugl-Mayer Assessment (FMA) and Modified Barthel Index (MBI) were adopted to evaluate the two groups before and after the treatment. The clinical efficacies of the two groups were also compared. Result The total effective rate was 100.0％ in the treatment group versus 87.0％ in the control group, and the between-group difference was statistically significant (P<0.01). The VAS, FMA and MBI scores were significantly changed after the treatment in both groups (P<0.01). After the treatment, the VAS, FMA and MBI scores of the treatment group were significantly different from those of the control group (P<0.05, P<0.01). Conclusion Warm needling plus Chinese medication for external application and rehabilitation training can obviously reduce post-stroke shoulder pain, and enhance the upper-limb motor function and activities of daily living.

Chloroplast genome sequences have comprehensive application prospects in DNA barcoding and chloroplast engineering in traditional Chinese medicine. The complete chloroplast genome of Magnolia officinalis sequenced by high-throughput pyrosequencing and a sequencing procedure was established. Fourteen contigs were obtained after de nove assembly. The sequencing percent of coverage was 99.99%. The chloroplast genome is 160 183 bp in size, and has a typical quadripartite structure with the large (LSC, 88 210 bp) and small copy (SSC, 18 843 bp) regions separated by two copies of an inverted repeat (IRs, 26 565 bp each). chloroplast genes were successfully annotated, of which 17 genes located in each IR region. The chloroplast genome features in Magnolia officinalis are nearly identical to those from other Magnoliid chloroplast genomes. Phylogenetic analyses were performed based on 81 shared coding-genes for a total of 9 Magnolia samples of 5 closely related species. Results showed that distinguishing among species was generally straightforward at the species and population level. This study confirmed the effectiveness of our chloroplast genome sequencing procedure. The chloroplast genome can provide distinguishing differences to help identify Magnolia officinalis and its closely related plants.
