Objective: To observe the therapeutic effect of acupuncture plus psychological intervention for postpartum depression.
Methods: By random number table, 85 patients with postpartum depression were divided into a treatment group and a control group. Forty-three cases in the treatment group were treated by acupuncture plus psychological intervention, once every day, five sessions per week, and rest at weekend. Forty-two cases in the control group were treated by oral administration of Fluoxetine Hydrochloride, 20 mg, once per day. The two groups were treated continuously for six weeks. The change of the score in Hamilton depression scale (HAMD) was observed and the therapeutic effect was summarized.
Results:The total effective rate was 90.7%in the treatment group and 90.5% in the control group. The difference in the total effective rate between two groups was not statistically significant (P>0.05). In the intra-group comparisons of HAMD scores two, four and six weeks after treatment in both groups with those before treatment, the differences were statistically significant (all P<0.05). In comparison between the two groups at the same time point, the differences in HAMD scores were not statistically significant (all P>0.05). Regarding the adverse events, 5 cases had nausea, 3 cases had dizziness, and 6 cases had poor appetite in the control group; no obvious adverse events happened in the treatment group.
Conclusion:Acupuncture plus psychological intervention for postpartum depression is as same as oral administration of Fluoxetine Hydrochloride in therapeutic effects, but it does not have adverse reaction.

Objective In order to standardize plantation and get bumper crops cultivation technique of Abrus cantoniensis Hance (a general term: "Herba Abri"). Methods To cultivate A. cantonients guiding by the instructive rules of productive quality and standard of management of Chinese medicinal materials, productive A. cantoniensis under good agriculture practice (GAP) promulgated by State Administration of Food and Drug. Results Comparing to production under non-GAP, the content of extract and flavones was higher, while the content of pesticide residue and heavy metal was lower under GAP. Conclusion Plantation of A. cantoniensis under GAP through choosing soil strictly, selecting seeds, optimizing pollution-free environment and friendly fertilizer and agriculture chemical, the harmful heavy metal and residues of pesticides amount in crude medicinal materials could be controled effectively so that the quality and output of A. cantoniensis could be improved.

In January 2021, an acute chemical poisoning incident occurred at a fluorine polymerization plant. Through the analysis of the occupational health situation of the enterprise, combined with the clinical manifestations of the poisoned patients and the laboratory examination results, it was determined that the incident was an acute poisoning incident caused by the inhalation of organic fluorine mixed gas in the fluorine polymerization plant. Subsequently, it was clarified that the accident was caused by the illegal operation of the employees of the fluorine polymerization plant, which caused the discharge of the organic fluorine mixed gas containing high concentration of octafluoroisobutene, resulting in the poisoning of the on-site construction personnel. In order to avoid the occurrence of similar incidents, enterprises should implement the main responsibility of safety production, regularly organize supervision and inspection, eliminate illegal operations, conduct safety education and training for the staff of the unit and outsourced staff, and improve the emergency rescue ability of sudden poisoning incidents.

Objective:To explore the construction and effect of biobank in biological research in nursing field.Methods:Through the establishment of a biological research plan for nursing in Affiliated Jinhua Hospital, Zhejiang University School of Medicine, the biobank in biological research for nursing was constructed from aspects of biological samples, instruments and equipment, operating software, biobanking team formation, personnel training and standardized process formulation.Results:In August 2020, the Nursing Department and Central Laboratory of Affiliated Jinhua Hospital, Zhejiang University School of Medicine established a biobank for biological research in the nursing field, formed a biobank team, conducted personnel training and formulated standardized procedures. From December 1, 2020 to June 30, 2021, biological samples were collected from 264 gastric cancer patients and 56 healthy controls, mainly including whole blood, serum and urine.Conclusions:The construction of biobank for biological research in nursing field can collect abundant biological samples, which lays a foundation for subsequent independent biological research in nursing field.

Atropa belladonna seedlings were used as experimental materials and cultivated by soil culture method. Different concentrations(0,0.05,0.1,0.2,0.5 mmol·L~(-1))of NO donor sodium nitroprusside(SNP) were sprayed on the leaves. The effects of different concentrations of SNP and different treatment time(4,8,12,16 d) on nitrogen metabolism, secondary metabolite content, precursor content of tropane alkaloid synthesis pathway and expression of key enzyme genes under 100 mmol·L~(-1) NaCl stress were studied. The results showed that with the prolongation of salt stress, the nitrogen metabolism and the accumulation of secondary metabolites of A. belladonna were inhibited to some extent. After treatment with different concentrations of exogenous SNP, the ammonium nitrogen content decreased dramatically, and the contents of nitrate nitrogen, free amino acid, soluble protein and the activities of key enzymes of nitrogen metabolism(NR, GS, GDH) were all greatly improved; the contents of precursor amino acids(ornithine, arginine) and polyamines(Put, Spd, Spm) in the secondary metabolic pathway have increased to varying degrees. The qRT-PCR analysis showed that exogenous SNP treatment can effectively promote the high expression of key enzyme genes PMT, TRⅠ and H6H in the secondary metabolic pathway of A. belladonna, and the production of hyoscyamine and scopolamine were increased notably. In summary, the application of appropriate concentration of SNP can effectively alleviate the inhibition of salt stress on the nitrogen metabolism and secondary metabolism of Atropa belladonna, and enhance its salt tolerance. Overall, 0.1 mmol·L~(-1) and 0.2 mmol·L~(-1) SNP treatment achieved the most remarkable effect.
