Neurofibromas are benign peripheral nerve sheath tumors. It is more common in neurofibromatosis type Ⅰ. However, isolated vagal nerve neurofibroma(VNN) of the neck is extremely rare, and only a few case reports have been reported. Its etiology and pathogenesis are not clear. The diagnosis is mainly based on pathological examination and immunohistochemistry, and surgical resection is the main treatment. This study reports a rare case of giant solitary vagus neurofibroma in the neck. The patient was a 29-year-old female who was found to have a mass on the right side of the neck by physical examination, which was considered to be a vagus nerve tumor by neck ultrasound and imaging examination. The tumor was completely removed during the operation, with the size of about 10.0 cm×2.5 cm, and the patient had no special discomfort. Postoperative pathology and immunohistochemistry confirmed neurofibroma. After surgery, the patient had right vocal cord paralysis, hoarseness, choking and paroxysmal cough. After swallowing function training and voice rehabilitation treatment in the department, the patient recovered satisfactorily. There was no complication and recurrence during the follow-up of 1 year. This article reviews the literature to improve the diagnosis and treatment of solitary vagus neurofibroma in the neck by combining its medical history, imaging features, pathology and immunohistochemistry, and surgical treatment.

Biosensors have become powerful tools for real-time monitoring of specific small molecules and precise control of gene expression in biological systems. High-throughput sensors for 1, 4-butanediamine biosynthesis can greatly improve the screening efficiency of high-yielding 1, 4-butanediamine strains. However, the strategies for adapting the characteristics of biosensors are still rarely studied, which limits the applicability of 1, 4-butanediamine biosensors. In this paper, we propose the development of a 1, 4-butanediamine biosensor based on the transcriptional regulator PuuR, whose homologous operator puuO is installed in the constitutive promoter PgapA of Escherichia coli to control the expression of the downstream superfolder green fluorescent protein (sfGFP) as the reporter protein. Finally, the biosensor showed a stable linear relationship between the GFP/OD600 value and the concentration of 1, 4-butanediamine when the concentration of 1, 4-butanediamine was 0-50 mmol/L. The promoters with different strengths in the E. coli genome were used to modify the 1, 4-butanediamine biosensor, and the functional properties of the PuuR-based 1, 4-butanediamine biosensor were explored and improved, which laid the groundwork for high-throughput screening of engineered strains highly producing 1, 4-butanediamine.

OBJECTIVE To provide reference for the adjustment of antibiotic treatment regimens, identification of adverse reactions, and individualized pharmaceutical care for melioidosis sepsis (MS). METHODS Clinical pharmacists participated in the intensive and eradicating therapeutic processes for an MS patient by using blood concentration and gene detection. Based on the literature, antibiotic treatment regimens of MS were adjusted by determining the blood concentrations of β-lactam and trimethoprim/ sulfamethoxazole (TMP/SMZ) and calculating PK/PD parameters. The causes of adverse drug reactions were analyzed and addressed by detecting drug-related gene polymorphisms through high-throughput sequencing. RESULTS Clinical pharmacists used blood concentration and genetic testing methods to propose adjustments to imipenem-cilastatin sodium dosage and analyze the causes of various adverse drug reactions. PK/PD targets were calculated by measuring the blood concentrations of β-lactam and TMP/SMZ. Clinical pharmacists explained to clinical doctors the compliance status of patients with melioidosis in sepsis and non- sepsis stages through reviewing guidelines and literature; the results of blood concentration and genetic test were used to analyze the correlation of neurotoxicity of MS patients with B14) IMP cmin, and it was found that nephrotoxicity was not related to the cmax of TMP/SMZ, but to the patient’s water intake. After whole-process antibiotic treatment, the patient’s condition improved and was discharged, and the adverse reactions were effectively treated. CONCLUSIONS Clinical pharmacists use blood concentration and genetic tests to assist clinicians in formulating MS treatment regimens, and provide whole-course pharmaceutical care for a MS patient. This method has improved the safety and effectiveness of clinical drug therapy.

OBJECTIVE To prepare progesterone-2-chloro-4-nitroaniline cocrystal (CNA) so as to improve the solubility of progesterone and primarily evaluate the safety of the progesterone cocrystal in vivo. METHODS Using progesterone as the main body and CNA as the ligand, progesterone-CNA cocrystal was prepared with solvent evaporation method. The cocrystal was characterized by X-ray single crystal diffraction, X-ray powder diffraction (XRPD), differential scanning calorimetry (DSC) and Fourier transform infrared spectroscopy (IR). The dissolution rate of cocrystal was compared with those of progesterone and physical mixture. Forty-eight female KM mice were randomly divided into normal group (phosphate buffer containing 0.1% dimethyl sulfoxide), progesterone group (16 mg/kg), CNA group (9 mg/kg), progesterone-CNA cocrystal low-dose, medium- dose and high-dose groups (6, 12.5, 25 mg/kg), with 8 mice in each group. They were given relevant medicine/solvent intramuscularly, once a day, for consecutive 14 d. The safety of cocrystal was evaluated primarily by determining/observing the changes in body weight, organ index, tissue morphology, blood routine indicators, and liver and kidney function indicators. RESULTS The new crystal structure in the X-ray single crystal diffraction results, the new characteristic peak in the XRPD pattern, the change of melting point in the DSC results, and the change of the characteristic peak position in the range of 3 500- 2 750 cm-1 and 1 700-1 250 cm-1 in the infrared spectrum all Δ 基金项目国家重点研发计划项目(No.2022YFC3502100) indicated that progesterone-CNA cocrystal was successfully *第一作者 硕士研究生 。研究方向 :药物制备技术与工艺 。 prepared, and the dissolution rate of cocrystal was more than E-mail:SWB_1221@163.com # 通信作者教授,硕士生导师,博士。研究方向:药物制备技术与 twice that of the progesterone raw material drug. The results of 工艺。E-mail:wuxx-415@126.com in vivo safety experiments showed that the mortality rate of all 中国药房 2023年第34卷第13期 China Pharmacy 2023 Vol. 34 No. 13 · 1567 · groups was zero. Compared with normal group, uterine indexes of mice in progesterone group and progesterone-CNA cocrystal groups were significantly increased (P>0.05), and endometrium was also thickened; there was no statistical difference in the changes of body mass, liver and kidney function, liver index, kidney index, the number of leukocyte, lymphocyte and neutrophil in routine blood test among those groups (P>0.05), and the morphology of liver and kidney tissue has also no significant difference. However, the number of plasma red blood cells in the progesterone group decreased significantly (P<0.05), and there was no statistical significance in the number difference of red blood cells among progesterone-CNA cocrystal groups (P>0.05). CONCLUSIONS The progesterone-CNA cocrystal is successfully prepared with good safety in vivo, which significantly improve the solubility of progesterone.

The anastomotic vessels between the superior mesenteric artery and the inferior mesenteric artery are vital to maintain the blood supply of the anastomosis and residual colon after colectomy. However, current studies of anastomotic vessels are facing four major obstacles: confusing nomenclature, large variability in data, diversification of research methods and incomplete information records. The existence of marginal artery has been widely proved, and its significance for blood supply is well recognized by relevant studies. In contrast, the Riolan′s arch, whose connotations constantly changed over history, can not refer to a specific structure accurately. Researchers should abolish the controversial names such as Riolan′s arch, select appropriate research methods and record the anastomotic vessels in detail, so as to improve the comparability between different results. The study of anastomotic vessels can help us to identify potential vascular disease, select the appropriate surgical approach, and provide appropriate treatment of the vessels in the operating area, so as to provide a theoretical foundation and practical basis for fine surgical maneuvers.
