AIM To explore the clinical effects of comprehensive treatment regimen of traditional Chinese medicine on patients with refractory rhinosinusitis.METHODS One hundred and sixty-four patients were randomly assigned into control group(82 cases)for 3-month intervention of comprehensive treatment regimen of western medicine(Physiological Seawater Nasal Spray,Budesonide Nasal Spray,Clarithromycin Tablets),and observation group(82 cases)for 3-month intervention of comprehensive treatment regimen of traditional Chinese medicine(Xinzhi Tongqiao Granules,Xinbai Nasal Fumigation Powder,acupuncture of sphenopalatine ganglion).The changes in clinical effects,subjective disease indices(clinical symptom scores,SNOT-20 score,Lung Meridian Heat Accumulation Syndrome score),objective disease indices(Lund-Kennedy score,T&T olfactory score,MTT,MTR),inflammatory indices(LTC4,IL-17a,IL-33,ECP),immune indices(CD4+,CD8+,Treg,Th17,CD4+/CD8+,Th17/Treg)and safety indices were detected.RESULTS The observation group demonstrated higher total control rate than the control group(P＜0.05).After the treatment and at 3-month follow-up,the two groups displayed decreased clinical symptom scores,inflammatory indices,CD8+,Th17,Th17/Treg,SNOT-20 score,Lung Meridian Heat Accumulation Syndrome score,Lund-Kennedy score,T&T olfactory score(P＜0.05),increased CD4+,Treg,CD4+/CD8+,MTR(P＜0.05),and shortened MTT(P＜0.05),especially for the observation group(P＜0.05).No obvious adverse reactions were observable in the two groups.CONCLUSION For the patients with refractory rhinosinusitis,the comprehensive treatment regimen of traditional Chinese medicine can safely and effectively improve inflammatory responses,immune functions and mucociliary motor functions,repair the status and functions of nasal mucosa,alleviate subjective and objective symptoms,and enhance life quality.

Objective To observe the efficacy and safety of Morinda officinalis oligosaccharides in the continuation treatment of mild and moderate depression.Methods An open,single-arm,multi-center design was adopted in our study.Adult patients with mild and moderate depression who had received acute treatment of Morinda officinalis oligosaccharides were enrolled and continue to receive Morinda officinalis oligosaccharides capsules for 24 weeks,the dose remained unchanged during continuation treatment.The remission rate,recurrence rate,recurrence time,and the change from baseline to endpoint of Hamilton Depression Scale(HAMD),Hamilton Anxiety Scale(HAMA),Clinical Global Impression-Severity(CGI-S)and Arizona Sexual Experience Scale(ASEX)were evaluated.The incidence of treatment-related adverse events was reported.Results The scores of HAMD-17 at baseline and after treatment were 6.60±1.87 and 5.85±4.18,scores of HAMA were 6.36±3.02 and 4.93±3.09,scores of CGI-S were 1.49±0.56 and 1.29±0.81,scores of ASEX were 15.92±4.72 and 15.57±5.26,with significant difference(P＜0.05).After continuation treatment,the remission rate was 54.59％(202 cases/370 cases),and the recurrence rate was 6.49％(24 cases/370 cases),the recurrence time was(64.67±42.47)days.The incidence of treatment-related adverse events was 15.35％(64 cases/417 cases).Conclusion Morinda officinalis oligosaccharides capsules can be effectively used for the continuation treatment of mild and moderate depression,and are well tolerated and safe.

An electrochemical chemical oxygen demand(COD)sensor was proposed based on a FTO/TiO2/PbO2 electrode and a thin-layer electrochemical cell.The FTO/TiO2/PbO2 electrode was characterized by X-ray photoelectronic spectroscopy(XPS),X-ray diffraction(XRD)spectroscopy and electrochemical technique,and the results indicated that the rapid decrease in the output signals of the electrochemical COD sensor could be attributed to oxidation of PbSO4 occurring on the surface of FTO/TiO2/PbO2 electrode.The PbO2 deposition time and concentration of Na2SO4 were further optimized and then the electrochemical COD sensor was challenged by real samples including laker water sample,river water sample and wastewater sample.The evolution trend of signals of the electrochemical COD sensor in response to lake and river water samples was identical with that obtained with the standard method(HJ/T399-2007,Water quality-determination of the chemical oxygen demand-fast digestion-spectrophotometric method).The electrochemical COD sensor exhibited significant increase in the signal intensity after the samples were switched from lake water to wastewater sample,and a mean value of 32.5 mg/L with relative standard deviation(RSD)of 6.8%were obtained after measuring 45 times the wastewater with COD value of 30 mg/L under a sampling interval of 400 s.The as-prepared electrochemical COD sensor possessed good promise in regular monitoring of COD,discharge of wastewater and industrial process control,with advantages such as a small sampling interval,mild reaction conditions and no requirement of toxic and harmful chemical reagents.

Refractory prolactinoma is the most common pituitary neuroendocrine tumor.Dopamine receptor agonists(DA)are the primary choice for drug treatment.Most patients with prolactinomas respond well to DA.However,a minority of prolactinomas patients still show resistance to DA.Although drug-resistant and refractory prolactinomas are rare in clinical practice,their treatment is extremely challenging.Even a combination of drug therapy,multiple surgeries,and radiotherapy may not yield satisfactory outcomes.Therefore,standardizing the diagnosis and treatment process and pathway for refractory prolactionmas and exploring more effective multidisciplinary collaborative treatment strategies are urgent problems to be solved.In the clinical management of refractory prolactinomas,it is often necessary to consider the patient's condition comprehensively,replace other types of DA,or consider surgery,radiotherapy,and immunotherapy,which requires multidisciplinary diagnosis and treatment.This review synthesizes the latest literature at home and abroad to systematically discuss the latest advances in drug therapy,surgery,and radiotherapy treatments for refractory prolactionmas,aiming to provide new ideas for basic research,clinical diagnosis and treatment.

The study identified the blood-entering components of Sijunzi Decoction after gavage administration in rats by UPLC-Q-TOF-MS/MS, and investigated the mechanism of Sijunzi Decoction in treating Alzheimer's disease by virtue of network pharmacology, molecular docking, and experimental verification. The blood-entering components of Sijunzi Decoction were identified based on the mass spectra and data from literature and databases. The potential targets of the above-mentioned blood-entering components in the treatment of Alzheimer's disease were searched against PharmMapper, OMIM, DisGeNET, GeneCards, and TTD. Next, STRING was employed to establish a protein-protein interaction(PPI) network. DAVID was used to perform the Gene Ontology(GO) annotation and the Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment. Cytoscape 3.9.0 was used to carry out visual analysis. AutoDock Vina and PyMOL were used for molecular docking of the blood-entering components with the potential targets. Finally, the phosphatidylinositol 3-kinase(PI3K)/protein kinase B(Akt) signaling pathway enriched by the KEGG analysis was selected for validation by animal experiments. The results showed that 17 blood-entering components were detected in the serum samples after administration. Among them, poricoic acid B, liquiritigenin, atractylenolide Ⅱ, atractylenolide Ⅲ, ginsenoside Rb_1, and glycyrrhizic acid were the key components of Sijunzi Decoction in treating Alzheimer's disease. HSP90AA1, PPARA, SRC, AR, and ESR1 were the main targets for Sijunzi Decoction to treat Alzheimer's disease. Molecular docking showed that the components bound well with the targets. Therefore, we hypothesized that the mechanism of Sijunzi Decoction in treating Alzheimer's disease may be associated with the PI3K/Akt, cancer treatment, and mitogen-activated protein kinase(MAPK) signaling pathways. The results of animal experiments showed that Sijunzi Decoction significantly attenuated the neuronal damage in the hippocampal dentate gyrus area, increased the neurons, and raised the ratios of p-Akt/Akt and p-PI3K/PI3K in the hippocampus of mice. In conclusion, Sijunzi Decoction may treat Alzheimer's disease by activating the PI3K/Akt signaling pathway. The findings of this study provide a reference for further studies about the mechanism of action and clinical application of Sijunzi Decoction.

During coronavirus disease 2019 epidemic, the treatment of severe trauma has been impacted. The Consensus on emergency surgery and infection prevention and control for severe trauma patients with 2019 novel corona virus pneumonia was published online on February 12, 2020, providing a strong guidance for the emergency treatment of severe trauma and the self-protection of medical staffs in the early stage of the epidemic. With the Joint Prevention and Control Mechanism of the State Council renaming "novel coronavirus pneumonia" to "novel coronavirus infection" and the infection being managed with measures against class B infectious diseases since January 8, 2023, the consensus published in 2020 is no longer applicable to the emergency treatment of severe trauma in the new stage of epidemic prevention and control. In this context, led by the Chinese Traumatology Association, Chinese Trauma Surgeon Association, Trauma Medicine Branch of Chinese International Exchange and Promotive Association for Medical and Health Care, and Editorial Board of Chinese Journal of Traumatology, the Chinese expert consensus on emergency surgery for severe trauma and infection prevention during coronavirus disease 2019 epidemic ( version 2023) is formulated to ensure the effectiveness and safety in the treatment of severe trauma in the new stage. Based on the policy of the Joint Prevention and Control Mechanism of the State Council and by using evidence-based medical evidence as well as Delphi expert consultation and voting, 16 recommendations are put forward from the four aspects of the related definitions, infection prevention, preoperative assessment and preparation, emergency operation and postoperative management, hoping to provide a reference for severe trauma care in the new stage of the epidemic prevention and control.

Objective: This cross-sectional investigation aimed to determine the incidence, clinical characteristics, prognosis, and related risk factors of olfactory and gustatory dysfunctions related to infection with the SARS-CoV-2 Omicron strain in mainland China. Methods: Data of patients with SARS-CoV-2 from December 28, 2022, to February 21, 2023, were collected through online and offline questionnaires from 45 tertiary hospitals and one center for disease control and prevention in mainland China. The questionnaire included demographic information, previous health history, smoking and alcohol drinking, SARS-CoV-2 vaccination, olfactory and gustatory function before and after infection, other symptoms after infection, as well as the duration and improvement of olfactory and gustatory dysfunction. The self-reported olfactory and gustatory functions of patients were evaluated using the Olfactory VAS scale and Gustatory VAS scale. Results: A total of 35 566 valid questionnaires were obtained, revealing a high incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain (67.75%). Females(χ2=367.013, P<0.001) and young people(χ2=120.210, P<0.001) were more likely to develop these dysfunctions. Gender(OR=1.564, 95%CI: 1.487-1.645), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), oral health status (OR=0.881, 95%CI: 0.839-0.926), smoking history (OR=1.152, 95%CI=1.080-1.229), and drinking history (OR=0.854, 95%CI: 0.785-0.928) were correlated with the occurrence of olfactory and taste dysfunctions related to SARS-CoV-2(above P<0.001). 44.62% (4 391/9 840) of the patients who had not recovered their sense of smell and taste also suffered from nasal congestion, runny nose, and 32.62% (3 210/9 840) suffered from dry mouth and sore throat. The improvement of olfactory and taste functions was correlated with the persistence of accompanying symptoms(χ2=10.873, P=0.001). The average score of olfactory and taste VAS scale was 8.41 and 8.51 respectively before SARS-CoV-2 infection, but decreased to3.69 and 4.29 respectively after SARS-CoV-2 infection, and recovered to 5.83and 6.55 respectively at the time of the survey. The median duration of olfactory and gustatory dysfunctions was 15 days and 12 days, respectively, with 0.5% (121/24 096) of patients experiencing these dysfunctions for more than 28 days. The overall self-reported improvement rate of smell and taste dysfunctions was 59.16% (14 256/24 096). Gender(OR=0.893, 95%CI: 0.839-0.951), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), history of head and facial trauma(OR=1.180, 95%CI: 1.036-1.344, P=0.013), nose (OR=1.104, 95%CI: 1.042-1.171, P=0.001) and oral (OR=1.162, 95%CI: 1.096-1.233) health status, smoking history(OR=0.765, 95%CI: 0.709-0.825), and the persistence of accompanying symptoms (OR=0.359, 95%CI: 0.332-0.388) were correlated with the recovery of olfactory and taste dysfunctions related to SARS-CoV-2 (above P<0.001 except for the indicated values). Conclusion: The incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain is high in mainland China, with females and young people more likely to develop these dysfunctions. Active and effective intervention measures may be required for cases that persist for a long time. The recovery of olfactory and taste functions is influenced by several factors, including gender, SARS-CoV-2 vaccination status, history of head and facial trauma, nasal and oral health status, smoking history, and persistence of accompanying symptoms.

Infection of pregnant women by Asian lineage Zika virus(ZIKV)is more likely to cause microcephaly in infants than African lineage ZIKV.To further clarify the differences in infectivity and stability between Asian and African lineage ZIKV,we selected Asian lineage SZ01 and African lineage MR766 strains for study in glial cells.First,we examined the differ-ence in infectivity between SZ01 and MR766 on U251 and U87 astrocytes,and T98G glioblastoma cells,by using CCK8 assays.Subsequently,we examined the tolerance of SZ01 and MR766 to 37 ℃ and 40 ℃ in the free and infected cell states,by using qRT-PCR or viral plaque assays.Finally,we examined the effect of repeated freezing and thawing on the stability of SZ01 and MR766 with viral plaque assays.ZIKV had higher infectivity in U251 and U87 than T98G,and SZ01 was more infectious to as-trocytes than MR766.SZ01 tolerated 40 ℃ better than MR766 in the free state.SZ01 proliferated faster than MR766 in glial cells at 40 ℃.The tolerance of SZ01 to repeated freezing and thawing was higher than that of MR766.The above findings sug-gest that the infectivity and stability of Asian lineage ZIKV are significantly higher than those of African lineage ZIKV,possi-bly because of its persistent infection and pathogenicity.

Objective: To investigate the effect of asiaticoside for fibrosis in lung tissues of rats exposed to silica and to explore its possible mechanism. Methods: 144 SD male rats were randomly divided into control group, model group, positive drug control group, asiaticoside high-dose group, medium-dose group and low-dose group, each group included 24 rats. Rats in the control group were perfused with 1.0 ml of normal saline, and the other groups were given 1.0 ml 50 mg/ml SiO(2) suspension. Gavage of herbal was given from the next day after model establishment, once a day. Rats in the positive drug control group were administration with 30 mg/kg tetrandrine and rats in the low-dose group, medium-dose group and high-dose group were given 20 mg/kg, 40 mg/kg and 60 mg/kg asiaticoside for fibrosis respectively. Rats in the control group and the model group were given 0.9% normal saline. The rats were sacrificed in on the 14th, 28th and 56th day after intragastric administration and collect the lung tissues to detect the content of hydroxyproline, TGF-β(1) and IL-18, observe the pathological changes of the lung tissues by HE and Masson staining and determine the expressions of Col-I, a-SMA, TGF-β in lung tissues by Western Blot. Results: On the 14th day, 28th day and 56th day after model establishment, the lung tissues of rats in the model group showed obvious inflammatory response and accumulation of collagen fibers, and the degree of inflammation and fibrosis increased with time. The intervention of asiaticoside could effectively inhibit the pathological changes of lung tissues. The contents of hydroxyproline, IL-18 and TGF-β1 in lung tissues of model group were higher than those in the control group (P<0.05) , while the level of hydroxyproline, IL-18 and TGF-β1 in asiaticoside groups were significantly decreased, and the difference was statistically signicant (P<0.05) . Compared with the control group, the expression levels of Col-I, TGF-β1and α-SMA in lung tissue of model group were increased (P<0.05) , while the expression level of Col-I, TGF-β1 and α-SMA were decreased after the intervention of asiaticoside, and the difference was statistically signicant (P<0.05) . Conclusion: Asiaticoside can inhibit the increase of Col-I, TGF-β1 and α-SMA content in the SiO(2)-induced lung tissues of rats, reduce the release of TGF-β1 and IL-18 inflammatory factors in lung tissue, and then inhibit the synthesis and deposition of extracellular matrix in rat lung tissue, and improve silicosis fibrosis.

Objective: To investigate the distribution of HIV-1 genetic subtypes and pretreatment drug resistance (PDR) among men who have sex with men (MSM) from 19 cities of 6 provinces in China. Methods: From April to November 2019, 574 plasma samples of ART-naive HIV-1 infected MSM were collected from 19 cities in Hebei, Shandong, Jiangsu, Zhejiang, Fujian, and Guangdong provinces, total ribonucleic acid (RNA) was extracted and amplified the HIV-1 pol gene region by nested polymerase chain reaction (PCR) after reverse transcription. Then sequences were used to construct a phylogenetic tree to determine genetic subtypes and submitted to the Stanford drug resistance database for drug resistance analysis. Results: A total of 479 samples were successfully amplified by PCR. The HIV-1 genetic subtypes included CRF01_AE, CRF07_BC, B, CRF55_01B, CRF59_01B, CRF65_cpx, CRF103_01B, CRF67_01B, CRF68_01B and unrecognized subtype, which accounted for 43.4%, 36.3%, 6.3%, 5.9%, 0.8%, 0.8%, 0.4%, 0.4%, 0.2% and 5.5%, respectively. The distribution of genetic subtypes among provinces is statistically different (χ²=44.141, P<0.001). The overall PDR rate was 4.6% (22/479), the drug resistance rate of non-nucleoside reverse transcriptase inhibitors, nucleoside reverse transcriptase inhibitors, and protease inhibitors were 3.5% (17/479), 0.8% (4/479) and 0.2% (1/479), respectively. The PDR rate of recent infections was significantly higher than that of long-term infections (χ²=4.634, P=0.031). Conclusions: The HIV-1 genetic subtypes among MSM infected with HIV-1 from 19 cities of 6 provinces in China are diverse, and the distribution of subtypes is different among provinces. The overall PDR rate is low, while the PDR rate of recent infections was significantly higher than that of long-term infections, suggesting the surveillance of PDR in recent infections should be strengthened.
