Sustained inflammatory responses are closely related to various severe diseases, and inhibiting the excessive activation of inflammasomes and pyroptosis has significant implications for clinical treatment. Natural products have garnered considerable concern for the treatment of inflammation. Huanglian-Wumei decoction (HLWMD) is a classic prescription used for treating inflammatory diseases, but the necessity of their combination and the exact underlying anti-inflammatory mechanism have not yet been elucidated. Inspired by the supramolecular self-assembly strategy and natural drug compatibility theory, we successfully obtained berberine (BBR)-chlorogenic acid (CGA) supramolecular (BCS), which is an herbal pair from HLWMD. Using a series of characterization methods, we confirmed the self-assembly mechanism of BCS. BBR and CGA were self-assembled and stacked into amphiphilic spherical supramolecules in a 2:1 molar ratio, driven by electrostatic interactions, hydrophobic interactions, and π-π stacking; the hydrophilic fragments of CGA were outside, and the hydrophobic fragments of BBR were inside. This stacking pattern significantly improved the anti-inflammatory performance of BCS compared with that of single free molecules. Compared with free molecules, BCS significantly attenuated the release of multiple inflammatory mediators and lipopolysaccharide (LPS)-induced pyroptosis. Its anti-inflammatory mechanism is closely related to the inhibition of intracellular nuclear factor-kappaB (NF-κB) p65 phosphorylation and the noncanonical pyroptosis signalling pathway mediated by caspase-11.

Gastric cancer is a prevalent malignancy of the digestive system, and traditional laparoscopic radical gastrectomy remains a crucial treatment modality. However, the abdominal wound associated with specimen removal during this procedure conflicts with contemporary concept of minimally invasive surgery. Natural orifice specimen extraction surgery (NOSES) is an emerging minimally invasive surgical technique that has gained increasing utilization in patients with gastrointestinal tumors, owing to its benefits of reduced wound, accelerated postoperative recovery, and diminished postoperative pain. In recent years, the extensive application of NOSES technology for colorectal cancer in China has provided theoretical support for the minimally invasive treatment of gastric cancer. With the standardization of community health examinations in China, the incidence of early gastric cancer diagnoses is expected to rise, making NOSES surgery the likely future trend in the surgical treatment for early gastric cancer. However, this area remains under-explored both domestically and internationally. This paper aims to synthesize prior literature and review the historical development, current research status, advantages and disadvantages, technical challenges, and future directions of completely laparoscopic radical treatment of distal gastric cancer utilizing NOSES.

The assay was used in HIV/AIDS surveillance sentinel sites to identify recent HIV-1 infection, to estimate HIV-1 incidence and understand the epidemic trends among men who have sex with men during 2011-2015. During 2011-2015, the HIV-1 incidence of men who have sex with men was 5.16%(95%CI: 4.65%-5.66%) in Sichuan Province. According to, a total of 9 cities had been divided into two type of regions: the first type(the proportion of live HIV/AIDS accounts for more than 0.1% of the permanent population, and the number of live HIV/AIDS has reached 500 cases and above) and the second type(the proportion of live HIV/AIDS accounts for 0.03% to 0.100% of the permanent population, and the number of live HIV/AIDS has reached 100-500 cases). During 2011-2015, the HIV-1 incidence of the second type was 4.24% (95%CI: 3.72%-4.76%). The HIV-1 incidence of men who have sex with men was at a high level. The spread of HIV-1 to the second region was possible.

Objective Data from the HIV/AIDS surveillance sentinel sites was used to identify the recent HIV-1 infections and to estimate the HIV-1 incidence and epidemic trends among intravenous drug users (IDU),MSM,female sex workers and men attending the sexually transmitted disease clinics in Sichuan province.Methods Specimens collected from IDUs,MSM,female sex workers and men attending the sexually transmitted disease clinics sentinel sites were confirmed as HIV-I positive and tested with BED-CEIA.Annual HIV-1 prevalence and incidence rates were calculated and the incidence was adjusted by McNermar method.Results A total number of 194 223 serum specimens were collected and HIV antibody tested,with 5 297 HIV-1 positive.4 640 of the positives underwent BED-CEIA,with 749 identified as recent infections.During 2011-2015,HIV-1 incidence rates of the four types of population appeared as 5.16％ (95％CI:4.65-5.66),0.22％ (95％CI:0.16-0.28),0.57％(95％CI:0.45-0.69),7.53％ (95％CI:6.06-9.01) and 0.44％ (95％CI:0.36-0.53) respectively.Significant differences were seen in the HIV-1 incidence rates.Conclusions The HIV-1 incidence rates of IDUs from other sentinel sites in Sichuan province,female sex workers and men attending the sexually transmitted disease clinics appeared low,showing that the AIDS prevention and control activities worked effectively.However,the HIV-1 incidence of MSM was still at high level and even rising,suggesting that HIV-1 transmission between MSM and IDUs was possible.

OBJECTIVETo investigate the drug resistance of HIV patients to the HIV-1 CRF01_AE and CRF07_BC strains in Sichuan province during 2010 to 2013.

METHODS1.5 ml of plasma were collected from AIDS patients who had been receiving anti-retroviral treatment for over 6 months but still had a HIV-1 virus load of over 1 000 copies/ml from January 1, 2010 to December 31, 2013 in Sichuan province. Genetic analysis of the HIV-1 pol gene was performed using self-established method, and patients with a positive drug-resistant HIV-1 pol gene mutation were included. HIV-1 poly gene was successfully sequenced for a total of 1 213 patients. Drug resistance of different HIV-1 strains was compared with χ2 test or Fisher exact test.

RESULTS558 cases (46.0%) of the 1 213 successfully sequenced patients were infected by HIV-1-strains with drug-resistant mutations, including 327 cases (58.6%) infected by CRF01_AE strain, 126 (22.6%) by CRF07_BC strain, 46 (8.2%) by CRF08_BC strain, 33 (5.9%) by B strain, 4 (0.7%) by C strain, 1 (0.2%) by CRF02_AG strain, and 21 (3.8%) by unidentified strains. Drug-resistant mutation analysis revealed that L33, F116, L74, Q151, and T69 resistance mutations occurred only in the CRF01_AE strain, while A71, K43, and Q58 resistance mutations occurred only in the CRF07_BC strain; in nuclear nucleoside reverse transcriptase inhibitors (NRTIs) and non nucleoside reverse transcriptase inhibitors (NNRTIs), CRF01_AE subtype strains showed highly resistant rate were higher than CRF07_BC, CRF08_BC and B subtype strains, with the differences were statistically significant (P<0.05).

CONCLUSIONThe drug-resistant HIV-1 strains in Sichuan mainly included the CRF01_AE and CRF07_BC strains, which had different resistance mutations.

Estimation the postmortem interval(PMI)is an important subject in forensic medicine practice.Recent research has found that the DNA molecular would degrade immediately following death,and the quantity of DNA in nuclear would be decreasing along with the elapse of the time since death.Seven parameter of cell nuclear,including the area and integral optical density,were chosen and the changes of DNA content in the brain cells of 15 rats were determined at every one hour during 48 horus after death by the auto TV imange analyses system.The results showed that the degradation rate of DNA in nuclear has a certainty relationship with early PMI in rats and indicated that the determination of the quantity of DNA in nuclear is the major method to estimate the PMI.
