Objective To investigate the clinical significance of quantitatively detecting serum cancer antigen 125(CA125) ,lactate dehydrogenase(LDH) ,β2-microglobulin(β2-MG) and serum ferritin(SF) in primary gastric lymphoma(PGL) .Methods The clini-cal data in 41 cases of PGL confirmed by Pathological examination were retrospectively analyzed on the serum CA 125 ,LDH ,β2-MG and SF levels ,and their relationship with the pathological type ,clinical phase ,grouping ,international prognostic index (IPI) andHe-licobacter pylori infection were compared .Results The serum levels of CA125 ,LDH ,β2-MG and SF in the Ⅲ + Ⅳ stage were high-er than those in the Ⅰ + Ⅱ stage in PGL patients(P<0 .05);the IPI scores in the middle-higher risk + high risk group were obvi-ously higher than those in the lower risk + low-middle risk group (P<0 .01) .There were no significant differences in the patho-logical type ,grouping and Helicobacter pylori infection .Conclusion Detecting the levels of CA125 ,LDH ,β2-MG and SF has the im-portant clinical value to the clinical phase and the prognostic judgment in PGL .

Objective To observe the effects of Jingning Granule on attention set shifting (AST) in rats with attention deficit hyperactivity disorder (ADHD).Methods Spontaneously hypertensive rats (SHR) were used as rat model of ADHD.Jingning granule (20.25, 10.125, 5.062 5 g/kg), Methylphenidate HCl Extended-release Tablets (Ritalin 6.75 mg/kg) and pediatric Huanglong granule (0.937 5 g/kg) were used as the intervention respectively and administered continuously for 17 days.The number of errors, burrowing times, and error rate in AST were used as the outcome measures.Results Compared with the normal control group, the number of error, error rate, and burrowing times increased in model group in Simple Discrimination (SD) phase, Compound Discrimination (CD) phase, Intra-Dimensional shift (IDS) phase, Reversal Learning (RL) phase, and Extra-Dimensional shift (EDS) phase;compared with the model group, Jingning granule reduced the frequency of error, error rate, and frequency of burrowing, and improved the attention set shifting defects in ADHD rat model.Conclusion ADHD model rats presented defected attention set shifting, and Jingning granule could effectively improve the attention set transfer ability in ADHD model rats.

Objective To explore the application value of comprehensive nursing path for patients with chronic pelvic inflammatory disease .Methods A total of 180 patients with chronic pelvic inflammation were randomly divided into observation group and control group on average .The control group received routine care for patients with chronic pelvic inflammatory disease , while the observation group underwent comprehensive comprehensive nursing path based on routine .The quality of life , effect of treatment and patients ’ satisfaction were compared .Results After intervention , the dimension assessment score of physical function , physical role , pain, health, vigor, social function, mental health and emotional function were (65.9 ±11.1),(67.8 ± 11.3),(68.1 ±10.0),(77.2 ±12.6),(70.8 ±11.0),(78.0 ±11.5),(77.6 ±11.3) and (80.4 ±10.7) in the observation group, which were better than those in the control group (t =6.983,9.042, 10.819, 19.037, 13.820, 25.174, 17.358, 28.974, respectively;P<0.01).The patients in the observation group had thirty six cured, twenty one dramatically effective, thirty effective and three invalid (Z=5.858,P<0.05). For assessment of satisfaction , there were seventy seven felt very satisfied , eleven satisfied and two unsatisfied (Z =6.678,P <0.05).Conclusions The comprehensive nursing path has a better therapeutic effect for patients with chronic pelvic inflammatory disease by improving the quality of life and treatment satisfaction .

ObjectiveTo analyze the community structure of endophytes in Panax quinquefolium root and explore the dominant endophytic bacteria and fungi， to provide scientific basis for the establishment of endophytic microbial bank in P. quinquefolium root. MethodInternal Transcribed Spacer （ITS） sequencing and 16S sequencing were performed on six P. quinquefolium root samples collected from Wendeng， Shandong province on PacBio Sequel Ⅱ. ResultA total of 8 phyla， 11 classes， 23 orders， 27 families and 53 genera of endophytic bacteria were identified in P. quinquefolium root， among which an unidentified Burkholderiaceae and an unidentified Rhizobiaceae were dominant. A total of 9 phyla， 23 classes， 35 orders， 43 families and 48 genera of endophytic fungi were identified in P. quinquefolium root， among which an unclassified Helotiales and Pseudogymnoascus were dominant. The community structure of endophytic bacteria revealed that the roots were selectively enriched with nitrogen-fixing bacteria such as unidentified Rhizobiaceae， Bradyrhizobium and Herbaspirillum， which suggested that nitrogen is important for the growth of P. quinquefolium root. The community structure of endophytic fungi indicated that P. quinquefolium in Shandong province might be infected by unclassified Helotiales. ConclusionThere is a rich diversity of endophytic bacteria and fungi in P. quinquefolium root， which provides scientific basis for studying the interaction of the plant with endophytic microorganisms and screening the endophytes to promote the growth of P. quinquefolium root.

ObjectiveTo discriminate the age of Arisaema Cum Bile， the combination of headspace solid-phase microextraction （HS-SPME） with gas chromatography-mass spectrometry （GC-MS） was applied to explore the differences of volatile components of unfermented， 1-year fermented， 2-year fermented， and 3-year fermented Arisaema Cum Bile. MethodSamples with different fermentation durations were collected and HS-SPME-GC-MS technology was employed to detect the volatile components of each sample. The relative contents of detected volatile components were processed and analyzed by chemometrics methods such as principal component analysis （PCA）， hierarchical cluster analysis （HCA）， and partial least squares discriminant analysis （PLS-DA）. ResultThe results showed that 145 volatile components were identified. Among these volatile components， the relative contents of heterocyclic， alcohols， aldehydes and aromatics were high. PCA， HCA， and PLS-DA can effectively separate Arisaema Cum Bile with four different ages. Based on variable importance in projection （VIP） value > 1， 73 markers of differential volatile components were identified. The content of 2，6，11-trimethyldodecane and m-xylene in unfermented samples was the highest， and the content difference between them and those in fermented samples was significant （P<0.05）. 2，3-butanediol was detected only in 1-year samples， octane was detected only in 2-year samples， and ethyl heptanoate was detected only in 3-year samples. These components can be used as odor markers for Arisaema Cum Bile with different fermentation years. ConclusionThe identification method of volatile components of Arisaema Cum Bile was established by HS-SPME-GC-MS technology， which can realize the rapid identification of unfermented， 1-year fermented， 2-year fermented， and 3-year fermented samples， and provide a scientific basis for the standardization of processing technology and quality standards of Arisaema Cum Bile.
