Objective:To investigate mental health state of primary-middle school teachers in Guangdong.Methods:1321 primary-middle school teachers in Guangdong were administered SCL-90. Results:The mental health of Primary-middle school teachers was worse than that of Chinese norm, and 23.92% of them was worse in at least one item. There was significant difference between different teacher groups. The mental health of teachers from primary school,especially the male teachers and teaders with lower educational level was an important issue.Conclusion: Primary-middle school teachers need more help to improve their mental health.

The MPN method was used to enumerate ammonia-oxidizing bacteria (AOB) in water and sediments of several shallow lakes. The suitable incubation time, medium types and substrate (ammonium sulphate) concentrations were studied. The results showed that, MPN values increased with the incubation time, reaching a stable maximum at some time stages, which was 40 days in all the samples for MSF medium. Among the three media used (XZ-AOB、MSF、SW), MSF give the highest MPN value. In addition, am- monium sulphate concentration in medium was an important factor affecting MPN estimation of AOB. Compared to AOB in lake sediments, AOB in lake water was more sensitive to ammonium sulphate concentration.

We predicted the anti-ulcerative colitis (UC) mechanism of Fructus Amomi based on network pharmacology. The anti-UC activity of Fructus Amomi were investigated by in vivo animal experiment, and the active components of Fructus Amomi were obtained through TCMSP, PubChem database and literature research. Animal welfare and experimental procedures follow the regulations of the Animal Ethics Committee of Institute of Materia Medica of Chinese Academy of Medical Sciences. The potential targets of the active components and UC were predicted by SwissTargetPrediction, GeneCards and TTD databases. The protein-protein interaction (PPI) network was constructed by String database and Cytoscape software was used to construct a visual network of active component-disease target and perform topological analysis. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses were performed using Metascape platform. The molecular docking of key components and core targets was carried out by Sybyl X software. We screened out a total of 12 active components and 189 disease-component overlapping targets. Enrichment analyses obtained 227 related GO items and 168 signaling pathways. According to the results of molecular docking, most active components of Fructus Amomi showed good affinity with the JAKs receptor family. Furthermore, Western blot results verified that Fructus Amomi could effectively inhibit JAK/STAT signaling pathway, indicating that Fructus Amomi might exert the anti-UC activity by regulating JAK/STAT signaling pathway.

Professor LU Zhi-zheng, one of the first traditional Chinese medicine masters, is good at using tenuifoliain clinical practice, which often brings unexpected surprises. Lu said, tenuifolia is a mild herbal medicine with the nature of upward dispersion and outward penetration but not dryness. Tenuifolia has the following functions: making people conscious, relieving sore throat, diverging incubated diseases, regulating functional activities of qi, sending up Yang, dispelling wind evil and eliminating dampness, and activating collaterals to relieve pain. When well used, it will not only enhance the effect of monarch drug, but also restrict the impetuosity nature in a prescription, achieving better efficacy.

BACKGROUND:Topping-off technique can be used for fixation treatment through the combination of fusion and interspinous dynamic device, in order to prevent or slow down the adjacent lumbar segment degeneration.
OBJECTIVE:To obverse the protective effect of Topping-off technique (posterior lumbar interbody fusion
procedure combined with the fixation of dynamic interspinous device Coflex) for the degenerative intervertebral disc. METHODS:A total of 32 patients with degenerative lumbar diseases who had been treated with Topping-off technique were included in this study. The Oswestry disability index, the Japanese Orthopaedic Association scores, range of motion for Coflex implanted segment and during the relative signal intensity of the Coflex implanted segment in MRI image were recorded and calculated preoperatively and the entire fol ow-up period.
RESULTS AND CONCLUSION:Al patients were fol owed-up for 20.6 months averagely. Up to the last fol ow-up, the Oswestry disability index and Japanese Orthopaedic Association scores were significantly improved when compared with those before treatment (P<0.001). There was no significant difference in the range of motion for Coflex implanted segment before and after treatment (P=0.19). The relative signal intensity of the Coflex implanted segment was significantly improved when compared with that before treatment (P<0.01). The clinical application of the Topping-off technique showed a protective effect on the intervertebral disc.

Objective Our purpose was to observe the renal pathological changes in the mouse modells of adriamy -cin-induced nephropathy in different periods .Method 48 healthy male BALB/c mice were randomly divided into control group and model group .The model group received a disposable tail vein injection of adriamycin 10.5 mg/kg body weight , and the control group received the same amount of saline .24-hour urinary protein , serum biochemical indexes and kidney pathological changes were dynamically observed for 12 weeks.Results Proteinuria of model mice appeared in the 2th week after ADR injection, which lasted to the end of the 12-week experiment, At the 8th week, the amount of urine protein reached a peak (P<0.05);The serum albumin was decreased at the 4th week, cholesterol was increased at 8th week.At the end of experiment, serum creatinine was also increased (P<0.05).Minimal change nephrotic syndrome (MCNS) was observed in model mice at the 4th week;the lesions in renal tissues at 8th weeks were more serious than that at 4th weeks, but glomerular sclerosis was unconspicuous .Focal segmental glomerulonephritis ( FSGS) was seen at the 12th week.The GSI of the model mice was(2.81 ±0.84)%, significantly higher than that of the control mice ((0.33 ±0.21)%) at 12th week(P<0.01).Conclusions A mouse model with adriamycin-induced-nephrosis can be successfully established by a disposable tail vein injection of adriamycin in a dose of 10.5 mg/kg body weight .The early manifest ation of this model is MCNS, and at a late stage , it may be changed into FSGS .
