The medicinal use of Malvae Semen has a long history. In this paper， by consulting the ancient materia medica， prescription， agronomy， literature and other aspects of the classics， the name， origin， evolution of scientific name， quality， harvesting and processing， functions and indications and others of Malvae Semen were systematically sorted out and verified， so as to provide a basis for the development and utilization of famous classical formulas containing this herb. According to the textual research， Shennong Bencaojing began to use Dongkuizi as the correct name， which was used in the past dynasties， and there were also aliases such as Kuicaizi， Huacai， and Kuizi. Through the original research， it can be seen that Kuicai is the mainstream original plant of Malvae Semen， that is， Malva verticillata var. crispa， the Alcea rosea and M. cathayensis are also used. In modern times， the seeds of Abutilon theophrasti have been passed off as Malvae Semen， while the seeds of M. verticillata var. crispa have rarely been used in medicine. And Abutili Semen has been another medicinal material with different efficacy since the collection of Newly Revised Materia Medica in the Tang dynasty. Since the Ming and Qing dynasties， the cultivation of Kuicai has been decreasing， while A. theophrasti is more common and easy to obtain， and Abutili Semen and Malvae Semen are similar in morphology and confused， which should be corrected. In addition， Malvae Fructus is a Mongolian customary medicinal herb， which is different from the traditional use of seeds in traditional Chinese medicine. Kuicai， as an important vegetable in history， was widely cultivated and gradually shrunk after the Song dynasty， it is now mainly produced in southern provinces. The quality evaluation of Malvae Semen is better for those with dry bodies， full grain， grayish brown color， no mud， and no impurities. The harvesting is generally in the autumn and winter. After drying， it is seeded， sieved peel and impurities， mashed， or slightly stir-fried to yellow-white color with gentle fire. It is sweet， cold and slippery in nature and taste， with the main effects of laxation， diuresis， lactation and elimination of swelling. The efficacy of Abutili Semen is clearing heat and removing toxicity， promoting diuresis and removing nebula， the efficacy is quite different from that of Malvae Semen. Based on the results of textual research， it is suggested that M. verticillata var. crispa should be used as the medicinal source of Malvae Semen in the development of famous classical formulas， the corresponding processing methods should be selected according to the requirements of drug processing in the formulas， while the raw products are recommended to be used if the processing is not specified.

The excessive accumulation of advanced glycosylation end products(AGEs), the end products of non-enzymatic glycosylation reactions, can be involved in the pathological processes of various ocular diseases through mechanisms such as oxidative stress, inflammatory responses and apoptosis. In this paper, we systematically reviewed the key role of AGEs in diabetic keratopathy, cataract, glaucoma, age-related macular degeneration(ARMD)and diabetic retinopathy(DR). It was found that AGEs activate signalling pathways such as NADPH oxidase, MAPK and NF-κB by binding to the receptor RAGE, leading to reactive oxygen species(ROS)generation, release of inflammatory factors, and vascular endothelial dysfunction, which in turn induces delayed corneal healing, cross-linking of lens proteins, optic nerve degeneration, formation of choroidal neovascularisation(CNV), and blood-retinal barrier(BRB)disruption. For example, in diabetic keratopathy, AGEs delay wound healing via the ROS/NLRP3 inflammatory vesicle axis; in cataract, ascorbic acid-mediated cross-linking of lens proteins due to AGEs directly impairs lens transparency; and in DR, AGEs exacerbate microvascular damage by regulating vasucular endothelial growth factor(VEGF)expression and pericyte apoptosis. In addition, this article discusses the advances and limitations of AGEs detection techniques, such as the potential application of lens AGEscan fluorescence assay in screening for diabetic complications, and the need to develop tissue-specific assays for aqueous humour and vitreous. For therapeutic strategies, the research directions of inhibiting AGEs production, blocking RAGE signalling pathway and developing anti-glycosylation drugs are proposed to emphasise their clinical value in delaying disease progression. This review not only integrates the molecular mechanisms and clinical associations of AGEs in ocular diseases, but also provides a theoretical basis for targeted interventions, which is of great significance in exploring novel diagnostic and therapeutic strategies.

Objective:To evaluate the relationship between inositol-requiring enzyme 1α-X box-binding protein 1 (IRE1α-XBP1) signaling pathway in endoplasmic reticulum and neutrophil extracellular traps during endotoxin-induced acute lung injury (ALI) in mice.Methods:Forty-eight SPF healthy male C57BL/6 mice, aged 6-8 weeks, weighing 25-30 g, were divided into 4 groups ( n=12 each) using a random number table method: control group (C group), STF-083010 group (ST group), lipopolysaccharide (LPS)-induced ALI group (ALI group) and LPS-induced ALI + STF-083010 group (ALI+ ST group). The ALI model was established by inhaling aerosolized LPS in ALI group and ALI+ ST group. The equal volume of aerosolized normal saline was inhaled in C and ST groups. IRE1α inhibitor STF-083010 50 mg/kg was intraperitoneally injected at 1 h before developing the model in ST and ALI+ ST groups, and the equal volume of normal saline was intraperitoneally injected in the other two groups. The mice were sacrificed after anesthesia at 24 h after developing the model. Bronchoalveolar lavage fluid (BALF) and lung tissues were collected for determination of the pathological changes (by light microscopy) which were scored, wet/dry lung weight (W/D) ratio, concentrations of interleukin-1beta (IL-1β), IL-18 and myeloperoxidase (MPO) in the BALF supernatant, and expression of phosphorylated IRE1α(p-IRE1α), XBP1s and citrullinated histone H3 (Cit H3) in lung tissues (using Western blot). Results:Compared to group C, the lung injury scores and W/D ratio were significantly increased at 24 h after developing the model, the concentrations of IL-1β, IL-18 and MPO in BALF were increased, and the expression of p-IRE1α, XBP1s and Cit H3 in lung tissues was up-regulated in ALI and ALI+ ST groups. Compared to group L, the lung injury scores and W/D ratio were significantly decreased at 24 h after developing the model, the concentrations of IL-1β, IL-18 and MPO in BALF were decreased, and the expression of p-IRE1α, XBP1s and Cit H3 in lung tissues was down-regulated in group ALT+ ST ( P<0.05). Conclusions:The IRE1α-XBP1 signaling pathway in endoplasmic reticulum is involved in endotoxin-induced ALI by up-regulating the expression of neutrophil extracellular traps in mice.

Objective To establish the drug use evaluation(DUE)standard of somatostatin and evaluate the rationality of its clinical use,so as to provide a reference for the rationally clinical application of somatostatin.Methods Based on the specification of somatostatin for injection,related guidelines and literature,DUE standard was established.Evaluate the rationality and standardization of the use of somatostatin for injection at Beihai People's Hospital from January 2021 to December 2021 based on the established DUE standards.Results A total of 407 patients were included,with a medication reasonable rate of 94.84％.The irrational use of drug included unreasonable indications(13 cases,3.19％),unreasonable drug use frequency(7 cases,1.72％),and unreasonable drug interactions(1 case,0.25％).Conclusion The somatostatin for injection DUE standard established is feasible and practical.The clinical application of somatostatin for injection in this hospital is basically reasonable,but there are still some irrational use of somatostatin,which should be strengthened for intervention.

Objective:To evaluate the role of inositol-requiring kinase 1α-X-box binding protein 1 (IRE1α/XBP1) signaling pathway in endoplasmic reticulumin in endotoxin-induced acute lung injury (ALI) in mice and the relationship with NOD-like receptor pyrin domain containing 3 (NLRP3) inflammasomes.Methods:Thirty-six SPF-grade healthy male C57BL/6 mice, aged 6-8 weeks, weighing 25-30 g, were divided into 3 groups ( n=12 each) according to the random number table method: control group (group C), endotoxin-induced ALI group (group ALI) and endotoxin-induced ALI+ STF-083010 group (group ST). The ALI model was established by inhaling nebulized lipopolysaccharide (LPS) 3 mg/ml for 30 min in ALI and ST groups, while the equal volume of nebulized normal saline was given in group C. IRE1α/XBP1 signaling pathway inhibitor STF-083010 50 mg/kg was intraperitoneally injected at 1 h before inhaling LPS in group ST, while the remaining two groups received the equal volume of normal saline intraperitoneally. Mice were sacrificed at 24 h after inhaling nebulized LPS or normal saline, bronchoalveolar lavage fluid (BALF) were collected and lung tissues were removed for microscopic examination of the pathological changes (by HE staining) which were scored and for determination of wet/dry lung weight ratio (W/D ratio), concentrations of interleukin-1beta (IL-lβ) and IL-18 in BALF (by enzyme-linked immunosorbent assay) and expression of phosphorylated IRE1α (p-IRE1α), XBP1s, NLRP3, ASC and caspase-1 in lung tissues (by Western blot). Results:Compared with group C, the W/D ratio, lung injury score and concentrations of IL-1β and IL-18 in BALF were significantly increased, and the expression of p-IRE1α, XBP1s, NLRP3, ASC and caspase-1 in lung tissues was up-regulated in group ALI and group ST ( P<0.001). Compared with group ALI, the W/D ratio, lung injury score and concentrations of IL-1β and IL-18 in BALF were significantly decreased, and the expression of p-IRE1α, XBP1s, NLRP3, ASC and caspase-1 protein in lung tissues was down-regulated in group ST ( P<0.001). Conclusions:IRE1α/XBP1 signaling pathway is involved in LPS-induced ALI in mice, and the mechanism is related to activation of NLRP3 inflammasomes.

Objective:To analyze the epidemiological characteristics of untreated 16-25 years old people living with HIV-1 (PLWH) in Dehong on the China-Myanmar border during 2009 to 2017, by using molecular network method and to provide references for precise prevention and reduction of the spread of HIV-1 in Dehong.Methods:Screening people living with HIV-1, collecting blood sample and separating plasma, extracting RNA were performed to amplify HIV-1 pol sequence, construct molecular network by HIV-TRACE program and conduct statistical analysis. Results:Among the 573 infected persons in the group, 319 were Chinese (55.67%), 254 were Burmese (44.33%); 351 were males (61%), and 222 were females (39%); 404 had heterosexual transmission (HET, 70.51%), 110 people injected drugs (PWID, 19.20%), 51 men had sex with men (MSM, 8.9%); genotypes included 252 unique recombinant forms (43.98%), and 222 had circular recombinant forms (39.02%), 76 had HIV-1 C (13.26%) and 23 HIV-1 B (4.01%) infection. The 83 molecular networks constructed through HIV-TRACE involved 250 PLWH, 49% were the China-Myanmar mixed network (41/83). Myanmar citizens were at high risk of accessing the China-Myanmar mixed network ( AOR=2.676, p=0.002). Chinese male PWID network assortativity is 0.34, Myanmar male PWID was 0.14, MSM was 0.12. Conclusions:There is a continuous risk of cross-border transmission of HIV-1 in Dehong on the China-Myanmar border; attention should be paid to the mixed transmission of MSM and Myanmar male PWID populations with other transmission routes.

Objective To investigate the surgical methods and the differences of postoperative complications in esophageal canccr patients aged 60 years and over undergoing different operation models.Methods A total of 542 elderly esophageal cancer patients who underwent thoracic surgery at our hospital between January 2010 and December 2016 were enrolled.Patients were divided into 4 groups:left thoracic incision operation group (n =202),lvor-Lewis two incisions operation group (right chest posterolateral and upper abdomen median) (n=251),three incision operation group (left neckright chest-abdominal midian (n =29),and McKneown under-endoscope minimally invasive operation group (n=60).Clinical data,including the postoperative days,numbers of lymph nodes dissection,pulmonary infection,serous membrane fluid,arrhythmia,chylous fistula,gastric emptying dysfunction and anastomotic leakage,were retrospectively compared between the four groups.Results There was no significant difference in the postoperative days,serous membrane fluid,arrhythmia,chylous fistula,gastric emptying dysfunction and anastomotic leakage (P ＞ 0.05).The number of lymph nodes dissection in Sweet group,Ivor-Lewis group,Mckeown operation group and minimally invasive Mckneown group were (12.9±7.4)、(19.3±8.6)、(14.3±6.9)and(15.4±7.3)respectively.The number of lymph nodes dissection was more in the Ivor-Lewis group than in the other three groups (F =23.915,P =0.000).Sweet group,Ivor-Lewis group,Mckeown group and minimally invasive Mckneown group were 31.7％、40.2％、24.1％ and 50.0％ respectively.The incidence of pulmonary infection was higher in the minimally invasive surgery group than in the other three groups (x2 =9.941,P =0.019).Conclusions Ivor-Lewis surgery is more effective in lymph nodes dissection and has a lower incidence of complications in elderly esophageal cancer patients.The minimally invasive surgery group has a higher incidence of pulmonary infection than in the other surgical groups,which may be related with the immaturity of endoscopic technique.

Objective To explore the expression of aquaporin-2 (AQP-2) in human fetus kidney and amniotic fluid at different stages of pregnancy.Methods Twenty-two cases of aborted fetuses' kidneys were collected.They were divided into 3 groups according to the pregnancy age:8 cases in 17-23 + 6 weeks,8 cases in 24-31 +6 weeks,and 6 cases in 32-38 +6 weeks.Western blot was used to examine the expression of AQP-2 in the kidney.Twenty-four cases of the amniotic fluid were collected,and they were divided into 3 groups according to the pregnancy age:10 cases in 17-23 +6 weeks,6 cases in 24-31 +6 weeks,and 8 cases in 32-38 +6 weeks.Eight cases of healthy adult morning urine were collected as positive controls.The AQP-2 protein in the amniotic fluid was detected with the method of enzyme-linked immunosorbent assay (ELISA) and the osmotic pressure of amniotic fluid at different stages of the pregnancy was measured with the freezing point osmometer.Results The expression of AQP-2 was increased with the extending of pregnancy age,and the AQP-2 expressions in fetus kidney of 17-23 +6 weeks,24-31 + 6 weeks and 32-38 +6 weeks were 0.986 ± 0.335,1.566 ± 0.272,and 2.080 ± 0.246,respectively,and the difference was significant (P ＜ 0.05).The AQP-2 detected from amniotic fluid was positively correlated with the result of AQP-2 in the kidney(r =0.985,P ＜ 0.05),and the AQP-2 expression also increased with the extending of pregnancy age:17-23 +6 weeks,24-31 +6 weeks,32-38 +6 weeks and adult urine was (30.253 ±5.843) mg/L,(35.103 ±7.271) mg/L,and (42.580 ± 1.230) mg/L and (46.493 ± 0.450) mg/L,respectively.The osmolality of the amniotic fluid of 17-23 +6 weeks,24-31 +6 weeks,32-38 +6 weeks was (272.600 ± 4.827) mmol/L,(252.00 ± 15.360) mmol/L,and (261.750 ±5.560) mmol/L,respectively,and the difference was significant(P ＜0.05).Conclusions The AQP-2 expression in human fetus kidneys has good correlation with amniotic fluid,which indicates that the level of AQP-2 of the amniotic fluid may reflect the expression of AQP-2 in the fetus kidney.

Objective To investigate the value of detrusor isovolumetric test(DIT)on female SUI with sus-pected detrusor contraction weakness. Methods A total of 86 SUI patients with suspected detrusor contraction weakness diagnosed by preoperative bladder cystometry(CMG)were enrolled in this study.DIT method was used to evaluate the bladder function. The difference of first sensation cystometry capacity, maximum cystometric capacity, bladder compliance and maximum detrusor pressure were compared between the two methods.Patients in group Ⅰwhowere diagnosed with normal detrusor function with DIT method underwent TOT surgery. Ninety normal SUI patients were selected as control group Ⅱ,who were diagnosed with normal detrusor function with CMG method. The surgery effect was compared between the two groups. Results By using DIT detection,there were 65 cases showed normal detrusor function of the 86 cases(75.6%).The maximum detrusor pressure with DIT was(31.2 ± 12.9)cm H2O versus(11.7 ± 3.1)cm H2O with cystometry(P＜0.05).No significant differences were observed in the first sensation cystometry capacity,maximum cystometric capacity and bladder compliance.The effective rate of TOT in both group Ⅰ and group Ⅱ was more than 95%,with no significantly difference between the two groups (P＞0.05). Conclusions DIT is a valuable method to evaluate the bladder function of female SUI patients with suspected detrusor contraction weakness.
