OBJECTIVE To explore the characteristics of adverse drug reaction (ADR) induced by semaglutide and provide a reference for clinically safe medication. METHODS Using search terms such as “semaglutide” and “adverse reactions” in both Chinese and English, the case reports about ADRs caused by semaglutide were searched and analyzed from PubMed, Web of Science, SpringerLink, CNKI, Chinese Medical Journal Full-text Database, Wanfang Medical Network and VMIS. RESULTS Overall 14 literature were included, involving 17 patients. Among 17 patients, 9 were female and 8 were male, with the age ranging from 25 to 80 years. Eight patients were given two or more drugs, and eight patients took 0.25 mg as the initial dose; the ADR occurred most frequently within 6 months (94.12%). Sixteen patients’ symptoms improved or recovered after drug withdrawal and symptomatic treatment. Eleven patients did not mention whether to continue to use semaglutide in the future. Nine patients underwent ADR correlation evaluation, and 1, 3, 1 and 4 cases were determined to be “definite”,“ probable”,“ possible”, and “doubtful” respectively. Semaglutide-induced ADRs involved multiple organs or systems, most of which were the digestive system (35.29%), followed by skin tissue (29.41%). Among them, acute gastric dilation, severe liver injury, calculous cholecystitis, bullous pemphigoid, eosinophilic fasciitis, acute kidney injury, acute interstitial nephritis, depression and acute hemolytic anemia were not mentioned in the instruction. CONCLUSIONS ADRs caused by semaglutide can occur in all ages, mainly within 6 months after medication, and mainly involve the digestive system, skin tissue, etc. Great attention should be paid to pharmaceutical care for those patients with liver and kidney dysfunction, neuropsychiatric diseases, glucose-6-phosphate dehydrogenase deficiency, etc. When ADR occurs, drug withdrawal and symptomatic treatment should be performed promptly to ensure patients’ medication safety.

Objective:To explore the clinical efficacy of Masquelet technique combined with tissue flap transfer in the treatment of infectious composite bone and soft tissue defects in the early and middle stages after internal fixation for tibial fractures.Methods:From October 2017 to November 2020, 12 patients (13 tibial fractures) with infectious bone and soft tissue defects in the early and middle stages after internal fixation were treated in the Department of Orthopaedics, 988th Hospital of the Joint Logistics Support Force of CPLA by two-phased surgery with retaining internal fixation. Phase I procedures were thoroughly removal of the infected lesions and failed screws, preserving internal implants as many as possible, implantation of absorbable calcium sulphate and an antibiotics blended string of beads into the distal and proximal medullary cavity of the fractured bones, filling the bone defect and wrapping the internal implants with antibiotics loaded bone cement. The size of defects was 3.5 cm × 5.0 cm-7.5 cm × 14.5 cm, and the flaps for wound coverage sized 4.0 cm × 5.5 cm-8.0 cm × 15.0 cm. As for the repair of donor site, 8 limbs were sutured directly, 5 limbs could not be closed completely, and the remaining wounds were covered by skin grafting after suture. Based on well control of infection and stable clinical signs, fillings of bone cement were then removed in Phase II surgery, or 6-9 weeks after primary surgery. Autologous cancellous bone pieces or composite allogeneic bone were fully implanted around the induction membrane formed by Masquelet technique, and auxiliary steel plates were implanted for internal fixation of unstable fractures. After discharge, the patients visited the outpatient clinic regularly, and combined with Wechat follow-up. The texture, colour and bone healing were observed. At the last follow-up, the function of the affected limbs were assessed according to Johner-Wruhs evaluation standard.Results:After Phase I surgery, 13 flaps survived smoothly without vascular compromise. The wounds healed in Phase I. Two patients (2 sides) had recurrent infections. Re-debridement was performed and external fixation was applied after removal of internal fixation. After Phase II surgery, all patients were included in 12-26 months of follow-up, with an average of 18 months. Thirteen lower leg fractures healed well, and the time of bone healing was 16-25 (average 19.5) weeks. The Johner Wruhs criteria was used in evaluation of the function of affected limbs, and it was found that 6 patients were in excellent, 5 in good and 2 in fair.Conclusion:It is feasible while preserving the internal implants, to use membrane induction technique (Masquelet technique) combined with flap transfer, together with the absorbable calcium sulphate antibiotic sustained-release beads as a carrier in the phased treatment of infectious bone defects and bone exposure in the early and middle stages after the surgery of tibial internal fixation. It also gives a higher rate of excellence in surgical outcome. This study explores a treatment procedure for traumatic bone infection combined with composite soft tissue defects.

Objective To provide theoretical reference and practical basis for accurately choosing the suitable packaging forms for different Injections. Methods Based on the raw materials in the common packaging forms of injections, the research and application progress on different packaging forms for injections were reviewed by analyzing the characteristics and technical requirements of different packaging forms, and the current registration information of pharmaceutical packaging materials in the Center for Drug Evaluation, NMPA were introduced. Results For preparations with small single-dose and low-cost, the ampoules or injection vials could be chosen. Powder injections are usually packaged in injection vials. For rescue medicines and valuable medicines, the pre-filled syringes could be chosen. For chronic disease treatment drugs (such as insulin) that require long-term injection, or some injections for emergency use, a pen-type syringe package that patients can inject themselves could be used. Neutral glass packaging or plastic packaging should be used for some acidic or alkaline. Conclusion The drug manufacturers should comprehensively consider the physicochemical properties of drugs, the performance of packaging raw materials, compatibility test results, price-cost, and convenience in carrying and use when choosing the appropriate packaging form to ensure the quality, safety, and effectivity of drugs.

Objective To analyze the polymorphism of Plasmodium lactate dehydrogenase (pLDH) gene and predict B-cell epitopes in pLDH peptides in four species of human malaria parasites. Methods The blood samples and epidemiological characteristics were collected from malaria cases in Yunnan Province registered in the National Notifiable Disease Report System. The pLDH genes of four human Plasmodium species were amplified using nested PCR assay and sequenced. The polymorphisms of pLDH genes was analyzed using the software MEGA version 7.0.26 and DnaSP version 5.10, and the B-cell epitopes were predicted in pLDH peptides using the Immune Epitope Database (IEDB). Results The sequences of P. vivax LDH (PvLDH), P. falciparum LDH (PfLDH), P. ovale LDH (PoLDH) and P. malariae LDH (PmLDH) genes were obtained from 153, 29, 17 and 11 blood samples from patients with P. vivax, P. falciparum, P. ovale and P. malariae malaria, respectively, which included 15, 2, 4 and 2 haplotypes and had a nucleotide diversity (π) of 0.104. A high level of intra-species differentiation was seen in the PoLDH gene (π = 0.012), and the π values were all < 0.001 for PvLDH, PfLDH and PmLDH genes. Active regions of B-cell antigen were predicted in the pLDH peptide chain of four human malaria parasites, of 4 to 5 in each chain, and the activity score was approximately 0.430. Among these peptide chains, the “86-PGKSDKEWNRD-96” short-peptide was a B-cell epitope shared by all four species of human malaria parasites, and the “266-GQYGHS (T)-271” short-peptide was present in PvLDH and PoLDH peptide chains, while “212-EEVEGIFDR-220” was only found in the PvLDH peptide chain, and “208-LISDAE-213” was only seen in the PfLDH peptide chain. Conclusions The PoLDH gene polymorphism may be derived from the weak negative purification selection, while PvLDH, PfLDH and PmLDH genes may maintain a relatively conservative state. There may be two B-cell epitopes “212-EEVEGIFDR-220” and “208-LISDAE-213” in the proximal region of the C terminal in the pLDH peptide chain, which is feasible to differentiate between P. vivax and P. falciparum infections.
