OBJECTIVE To provide a reference for the pharmaceutical care of a patient with type 2 diabetes mellitus(T2DM)and limb-girdle muscular dystrophy(LGMD)who developed euglycemic diabetic ketoacidosis(euDKA)after taking empagliflozin.METHODS Clinical pharmacists provided pharmaceutical care for a patient with T2DM and LGMD who developed euDKA after taking empagliflozin.According to the patient's recent use of medications and his conditions,clinical pharmacists assessed the correlation between euDKA and empagliflozin as"very likely".As to euDKA,clinical pharmacists suggested discontinuing empagliflozin and metformin,and giving intravenous infusion of 10％Glucose injection instead of 5％Glucose injection for fluid resuscitation.Clinical pharmacists monitored the patient's laboratory indicators such as arterial blood gas analysis,blood/urine ketones and electrolytes.They assisted physicians to decide when to stop intravenous supplements of liquid and insulin.Clinical pharmacists also assisted physicians to adjust the antidiabetic drugs and educated the patient to avoid empagliflozin or other sodium-glucose linked transporter 2 inhibitors(SGLT2i).RESULTS Physicians adopted the suggestions of clinical pharmacists.After treatment,the patient's condition improved,and he was allowed to be discharged with medication.CONCLUSIONS euDKA is a relatively rare and serious adverse reaction associated with SGLT2i,and the patients with LGMD are susceptible to euDKA.Clinical pharmacists assist physicians in developing personalized medication plans by evaluating the association between euDKA and empagliflozin,adjusting medication regimens,conducting pharmaceutical monitoring,and other pharmaceutical services.Meanwhile,they provide medication education to patients to ensure their medication safety.

Objective:To develop and verify a predictive model for hip fracture risk in the aged patients with knee osteoarthritis (KOA) on the basis of analysis of the risk factors associated with the hip fracture.Methods:A retrospective study was conducted to analyze the 701 patients who had been diagnosed with KOA (Kellgren-Lawrence grades 1 to 4) at Dongyang Hospital affiliated to Wenzhou Medical University from September 2013 to September 2023. The cohort consisted of 275 males and 426 females with an age of (76.5±8.4) years. The patients were divided into a fracture group ( n=145) and a fracture-free group ( n=556) based on whether a hip fracture occurred during the follow-up period. The 2 groups were compared in terms of age, gender, comorbidities, albumin level, absolute lymphocyte count, and Kellgren-Lawrence grade, etc. The items with P<0.05 were analyzed by a multivariate logistic regression model to identify the risk factors for hip fracture in the aged KOA patients. A clinical prediction model based on the above risk factors was constructed and validated for hip fracture risk in the aged KOA patients. Results:Multivariate logistic regression analysis identified the following as independent risk factors for hip fracture in the aged KOA patients: female ( OR=2.009, 95% CI: 1.280 to 3.154, P=0.002), age ≥75 years ( OR=2.313, 95% CI: 1.493 to 3.583, P=0.001), Kellgren-Lawrence grades of 3-4 ( OR=2.348, 95% CI: 1.533 to 3.596, P=0.001), an albumin level <35 g/L ( OR=0.316, 95% CI: 0.191 to 0.522, P=0.001), and an absolute lymphocyte count <0.8×10 9/L ( OR=0.133, 95% CI: 0.069 to 0.253, P=0.001). The area under the ROC curve (AUC) for the model developed by this study was 0.753 in the training set and 0.815 in the validation set ( P<0.05). The Hosmer-Lemeshow goodness-of-fit test showed that the consistency between the predicted risk and the actual risk was good in the training and validation sets ( P<0.05). The calibration curves for both the training and validation sets closely aligned with the ideal curve. The clinical decision curve analysis showed that the nomogram model had a good net benefit rate and a good predictive potential. Conclusions:Female, age ≥75 years, Kellgren-Lawrence grades of 3-4, an albumin level <35 g/L, and an absolute lymphocyte count <0.8×10 9/L are independent risk factors for hip fracture in the aged KOA patients. Since the nomogram prediction model based on these risk factors is satisfactory in discrimination and calibration, it shows a certain predictive ability and application value in clinic.

Objective To compare the clinical effects of arthroscopically-assisted reduction and internal fixation(ARIF)combined with enhanced recovery after surgery(ERAS)and open reduction and internal fixation surgery(ORIF)in the treatment of posterior lateral tibial plateau fractures.Methods Seventy patients with posterior lateral tibial plateau fractures in the Department of Orthopaedics,Xuzhou Central Hospital,from January 2020 to November 2022 were retrospectively selected and divided into ARIF group(with ERAS,n=32)and ORIF group(without ERAS,n=38)according to the treatment methods.All patients were evaluated for fracture type by imaging examination after admission.The operation time,length of hospital stay,early postoperative pain score(evaluated by visual analogue scale[VAS]),knee joint function(evaluated by hospital for special surgery[HSS]scale)at 3 months and thigh circumference difference at 6 months postoperatively were compared between the two groups.Results The operation time in the ARIF group was significantly shorter than that in the ORIF group([67.84±9.89]min vs[85.16±9.18]min,P＜0.001),and the length of hospital stay was significantly shorter in the ARIF group([7.13±1.41]d vs[8.74±1.84]d,P＜0.001).On the third day after operation,the VAS score in the ARIF group was significantly lower than that in the ORIF group([4.00±1.44]vs[5.39±1.24],P＜0.001).ARIF group had better joint function than ORIF group 3 months after operation,and the difference of 10 cm thigh circumference on patella in ARIF group was smaller than that in ORIF group 6 months after operation.Conclusions Compared to ORIF,patients with posterior lateral tibial plateau fractures treated with ARIF combined with ERAS showed faster postoperative recovery,shorter hospital stay,and more precise clinical efficacy.

The purpose of this study was to clone and characterize the ZFP36L1 (zinc finger protein 36-like 1) gene, clarify its expression characteristics, and elucidate its expression patterns in different tissues of goats. Samples of 15 tissues from Jianzhou big-eared goats, including heart, liver, spleen, lung and kidney were collected. Goat ZFP36L1 gene was amplified by reverse transcription-polymerase chain reaction (RT-PCR), then the gene and protein sequence were analyzed by online tools. Quantitative real-time polymerase chain reaction (qPCR) was used to detect the expression level of ZFP36L1 in intramuscular preadipocytes in different tissues and adipocytes of goat at different differentiation stages. The results showed that the length of ZFR36L1 gene was 1 224 bp, and the coding sequence (CDS) region was 1 017 bp, encoding 338 amino acids, which was a non-secretory unstable protein mainly located in nucleus and cytoplasm. Tissue expression profile showed that ZFP36L1 gene was expressed in all selected tissues. In visceral tissues, the small intestine showed the highest expression level (P < 0.01). In muscle tissue, the highest expression level was presented in longissimus dorsi muscle (P < 0.01), whereas the expression level in subcutaneous adipose tissue was significantly higher than that in other tissues (P < 0.01). The results of induced differentiation showed that the expression of this gene was up-regulated during adipogenic differentiation of intramuscular precursor adipocytes (P < 0.01). These data may help to clarify the biological function of the ZFP36L1 gene in goat.

In this study, we cloned the complete sequence coding for aminoacids in protein (CDS) of goat ST13 gene, analyzed the bioinformation of it, and explored the expression pattern in different goat tissues and goat subcutaneous preadipocytes at different differentiation stages. To be specific, ST13 gene was cloned by reverse transcription PCR (RT-PCR), and the bioinformation was analyzed by online tools or software. The expression in various goat tissues and subcutaneous preadipocytes at different differentiation stages was detected by quantitative reverse transcription PCR (qRT-PCR). The results showed that the cloned goat ST13 gene was 1 380 bp, with CDS of 1 101 bp, encoding 366 amino acids. Protein prediction results showed that ST13 had 26 phosphorylation sites and that some sequences were highly hydrophilic and unstable. Moreover, ST13 was a non-transmembrane and non-secretory protein. Subcellular localization demonstrated that ST13 was mostly distributed in the nucleus (69.6%). Phylogeny analysis suggested that goat ST13 had the highest identity to sheep ST13. Tissue expression pattern showed that ST13 gene expressed in all of the collected 13 tissues of goat, including heart, liver, spleen, lung and kidney, especially in triceps brachii and subcutaneous fat (P < 0.01) and that the expression among heart, liver, spleen, lung, kidney, large intestine, small intestine and pancreas was insignificantly different (P > 0.05). In addition, according to the temporal expression pattern in adipocytes, the expression of ST13 was up-regulated in differentiated adipocytes, and the expression was the highest at the 108th hour of induction, significantly higher than that at other time points (P < 0.01). In conclusion, this gene expresses in various tissues of goat and regulates the differentiation of goat subcutaneous adipocytes.
