Objective To investigate the impact of temperature intervention on pain and catheterization outcomes in premature infants undergoing peripherally inserted central catheter(PICC)placement.Methods A total of 70 premature infants who underwent PICC placement and met the inclusion criteria were selected from the Neonatology Department of a tertiary children's hospital in Kunming,Yunnan,from January 2023 to December 2023.They were randomly divided into a control group(n=35)and an observation group(n=35)using a random number table.The control group underwent the standard PICC placement procedure;the observation group underwent temperature intervention measures based on the control group,which included using iodine tincture warmed to 37℃for disinfection,applying warm compresses to the catheterization site with heated hands of the operator,and using saline warmed to 37℃during catheter insertion and skin cleansing.Pain scores measured by the Premature Infant Pain Profile(PIPP),blood oxygen saturation,heart rate,success rates of single puncture and single catheter insertion,incidence of complications,and occurrence of hypothermia post-catheterization were compared between the two groups.Results The PIPP during disinfection,puncture,catheter insertion,and cleansing were significantly lower in the observation group than in the control group(P<0.05);the average blood oxygen saturation in the observation group was higher than that in the control group,with a lower difference compared to the control group(P<0.05);the difference and average heart rate during catheterization in the observation group were both lower than those in the control group(P<0.05);the success rates of single puncture and single catheter insertion,as well as the incidence of hypothermia post-catheterization in the observation group,were both lower than those in the control group(P<0.05),while the comparison of complication rates between the two groups showed no statistically significant difference(P>0.05).Conclusion Implementing temperature intervention during PICC placement in premature infants can effectively reduce pain,maintain stable vital signs,improve the success rates of single puncture and catheter insertion,and effectively prevent the incidence of hypothermia.

Type 2 diabetes mellitus （T2DM） is based on insulin resistance （IR） and insulin secretion deficiency， with the specific mechanisms still unclear. Current research involves mechanisms such as glycolipid toxicity， inflammatory response， oxidative stress damage， and mitochondrial dysfunction. Modern traditional Chinese medicine （TCM） scholars have named it "blood glucose collateral disease" based on the clinical characteristics and natural progression of T2DM. This condition is primarily manifested as abnormal blood sugar levels in the early stages， and as the disease progresses， it gradually causes widespread damage to the body's veins and collaterals， ultimately leading to lesions in vessels and collaterals. Among these， "spleen heat" （obesity type） is the most common clinical type of T2DM. The concept of "internal heat-induced elimination" runs through both the onset and complications of T2DM， with internal heat being a key factor in its pathogenesis. The clinical application of Dahuang Huanglian Xiexintang and its modifications has achieved significant therapeutic effects. This paper reviews the origins and treatment characteristics of Dahuang Huanglian Xiexintang， along with clinical application research and experimental studies related to T2DM treatment， involving mechanisms for regulating glucose and lipid metabolism disorders， improving IR， modulating inflammatory responses， combating oxidative stress damage， regulating autophagy-related signaling pathways， modulating intestinal flora， inhibiting pyroptosis， and alleviating endoplasmic reticulum stress， with the purpose to provide direction for further research on the prevention and treatment of T2DM and its related complications， to offer reference for developing Dahuang Huanglian Xiexintang as a rapid hypoglycemic Chinese patent medicine for obese T2DM， and to better guide the clinical promotion of this drug.

OBJECTIVE: To establish logistic regression model for prostate cancer and provide basis for prostate biopsy.
 METHODS: A total of 117 cases of prostate biopsy were retrospectively analyzed in chronological sequence. All cases were assigned into a model group (n=78) and a validation group (n=39). Logistic regression model was established and its value was estimated by receiver operating characteristic (ROC) curve. 
 RESULTS: Digital rectal examination(DRE), transrectal ultrasound(TRUS), MRI, prostate-specific antigen density (PSAD), and free PSA/total PSA (fPSA/tPSA) were the influential factors for prostate biopsy (P<0.01). The established logistic regression model for prostate cancer by regression coefficient was: logit P=-2.362+2.561×DRE+1.747×TRUS+2.901×MRI+1.126×PSAD-
2.569×fPSA/tPSA and area under curve was 0.907. When the cutoff aimed at 0.12, the sensitivity and specificity were 81.80% and 89.30%, respectively.
 CONCLUSION Logistic regression model for prostate cancer can provide sufficient basis for prostate biopsy. Prostate biopsy should be performed when P value is more than 0.12.

Objective To evaluate MSCT appearance and impaction of Ⅴ, Ⅷ segments' hepatic venous congestion ( HVC ) on hepatic functional recovery in living donor liver transplantation (LDLT).Methods In this study, 83 patients undergoing LDLT in our hospital were included, all subjects received plain and contrast MSCT examinations at early stage (within 1 month) and later stage (3 months later) after LDLT. MSCT appearance of HVC was recorded, at the same time, gutamic pyruvic transaminase ( ALT),glutamic oxalacetic transaminase (AST), total bilirubin (TB) and prothrombin time (PT) of 1 to 7 days after LDLT between congestion group and non-congestion group were recorded and compared.Results Segments Ⅴ and Ⅷ congestion was identified by after LDLT CT scanning in 20 patients (24. 10% ). Congestion volume and congestion ratio was (218. 25 ± 130. 29) cm3 and 16. 68% ±8. 81%,respectively. HVC often appear as hypoattenuation on plain CT scan and arterial phase, mixed or hyperattenuation on portal vein phase. There was no significant difference of ALT, AST, TB and PT after LDLT between congestion group and non-congestion group (P ＞ 0. 05). Conclusions MSCT is a valuable method to evaluate Ⅴ, Ⅷ segments' HVC after LDLT, most HVC has no impaction on hepatic functional recovery in LDLT patients.

OBJECTIVETo investigate the neuroprotective effects of the constituents in Herba Erigerontis on neuroblastoma SH-SY5Y cells, and find out its possible material foundation in treating Alzheimer's disease (AD).

METHODDifferent combinations of the three constituents in Herba Erigerontis were prepared according to the orthogonality experiment, and the indexes (MTT reduction assay, lipid peroxidation and expressions of nAChR alpha7 protein)were observed upon the SH-SY5Y cells followed by treatment of these combinations and beta-amyloid peptide (AP). The pharmacology data thus obtained and peak data in UPLC fingerprint were analyzed through ANOVA and correlationship by SPSS to give the information of active possible material foundation.

RESULTConstituents B and C showed clear activity and peaks of 4, 7-12 did positive correlationship according to the correlation of fingerprints and pharmacology.

CONCLUSIONThis study makes a valid approach for deducing the active constituents even the exact compounds against neurotoxicity induced by Abeta by correlation of fingerprints and pharmacology.
