OBJECTIVETo observe the therapeutic efficacy and safety of gonadotropin-releasing hormone agonist (GnRHa) combined Wenshen Xiaozheng Decoction (WXD) in auxiliary treating endometriosis after laparoscopy.

METHODSOne hundred and thirty-four endometriosis patients with confirmative pathological diagnosis were assigned to three groups depending on whether they would receive adjuvant therapy or Chinese medicine treatment, i.e., the control group, the observation 1 group, and the observation 2 group. The 22 patients in the control group received no adjuvant therapy after laparoscopy. The 42 patients in the observation 1 group were treated with GnRHa 3.6 mg by subcutaneous injection starting from the 1st day to the 5th day of menstruation, once per 28 days. The 70 patients in the observation 2 group were treated with GnRHa 3.6 mg by subcutaneous injection in combination with WXD starting from the 1st day to the 5th day of menstruation, once per 28 days. They also took WXD for 7 doses, one cycle per every 28 days. The treatment lasted for three to six months. Serum levels of estradiol (E2), follicle-stimulating hormone (FSH), luteinizing hormone (LH), and cancer antigen 125 (CA125), as well as clinical efficacy, and adverse drug reactions were observed before and after treatment.

RESULTSThere was statistical difference in serum levels of E2, FSH, or LH between the control group and the observation 1 and 2 groups (P < 0.05). There was no statistical difference in serum levels of E2, FSH, or LH between the observation 1 group and the observation 2 group (P > 0.05). There was statistical difference in the clinical efficiency among the 3 groups (P < 0.05). There was statistical difference in the pre-post difference of CA125 levels among the three groups (P < 0.01). Compared with the control group, there was no statistical difference in the pre-post difference of CA125 levels between the observation 1 group and the observation 2 group (P > 0.05). No obvious adverse reaction occurred during the treatment.

CONCLUSIONSGnRHa combined WXD showed confirmative clinical efficacy in treating endometriosis after laparoscopy. It also could lower serum levels of E2, FSH, and LH levels. So it was an ideal solution for treatment of endometriosis.

This research explored the synergistic effects and the potential mechanisms of RCE-4 and various nonsteroidal anti-inflammatory drugs (NSAIDs) on the proliferation of cervical cancer Ca Ski cells. The MTT assay and CalcuSyn V2.0 software were used to detect cell proliferation and calculate the combination index (CI); the expression levels of various proteins were analyzed using Western blot assay; mitochondrial membrane potential (MMP) was assessed using JC-1 staining; acridine orange/ethidium bromide (AO/EB) double-fluorescence staining was used to detect the apoptosis of Ca Ski cells; a co-immunoprecipitation (Co-IP) assay was used to analyze the relative content of Bcl-2-Beclin 1 complex in Ca Ski cells. The results demonstrate that the combination of RCE-4 and NSAIDs increases the inhibition of Ca Ski cells compared to the single-RCE-4 group, and celecoxib provided the best synergistic effect among the four NSAIDs tested, with a CI of 0.32. The combination of RCE-4 and celecoxib significantly down-regulated the expression of cyclooxygenase-2 (COX-2) and nuclear transcription factor-κB (NF-κB), and promoted the expression of non-steroidal anti-inflammatory drugs activity gene-1 (NAG-1). In addition, autophagy induced by RCE-4 was markedly inhibited in combination with celecoxib, which was associated with down-regulation of the expression of microtubule-associated protein 3 (LC3)-II, Beclin 1, p62 and autophagy-related gene (ATG) 3/4B/5/7/14. RCE-4-induced apoptosis was significantly enhanced by altering the depolarization of mitochondrial membrane potential and the expression of B cell lymphoma-2 (Bcl-2), B cell lymphoma-xl (Bcl-xl), Bcl-2 associated X protein (Bax), Bcl-2/Bcl-xl-associated death promoter (Bad) and cleaved cysteinyl aspartate specific proteinase (cleaved-caspase) 3/7/9. Furthermore, the formation of the Bcl-2-Beclin 1 complex was significantly inhibited in Ca Ski cells treated with RCE-4 in combination with celecoxib. Taken together, this research shows that the combination of RCE-4 and celecoxib has a significant synergistic effect on the proliferation of Ca Ski cells by promoting apoptosis, inhibiting autophagy and disturbing the formation of the Bcl-2-Beclin 1 complex, which may be a novel strategy to increase the sensitivity of anti-cervical cancer drugs.

Objective To analyze epidemiological characteristics and changing trends of common respiratory infectious diseases among 6-19 year-old population in Shenzhen from 2013 to 2021, and to provide a reference for prevention and control. Methods Data of influenza, mumps and varicella reported cases among the population aged 6-19 years in Shenzhen from 2013 to 2021 were collected, and descriptive methods and Joinpoint regression model were used to analyze epidemiological characteristics and trends of incidences. Results Between 2013 and 2022 in Shenzhen, the average annual incidence rates of influenza, mumps, and varicella among the population aged 6-19 years were 961.44/100 000, 157.70/100 000, and 664.34/100 000 respectively. The incidence of influenza showed an upward trend in 10 years, with an annual percent change (APC) of 52.88% (P<0.05). The incidence of mumps and varicella both showed an 'up-down' trend, with an inflection point in 2019. The incidence APC of mumps were 11.51% and -43.49%, respectively (P>0.05), while the incidence APC of varicella were 28.88% and -50.03%, respectively (P<0.05), respectively. From the point of seasonal distribution, the incidence of three infectious diseases all showed bimodal distribution, with peaks in winter (December to January of the following year) and at the turn from spring to summer (April to June). The proportion of reported cases of three infectious diseases among people aged 6-<10 years old exceeded 60%. The proportion of varicella cases among people aged 10-<15 and 15-19 was on the rise. The incidence rate of influenza and varicella in people aged 15-19 years increased fastest, with APCs of 77.89% and 33.00%, respectively (both P<0.05). Conclusions The trend analysis based on Joinpoint regression model displayed that the reported incidence of influenza among people aged 6-19 years in Shenzhen during 2013-2022 showed an upward trend, and the incidence of varicella had an 'up-down' trend. Children aged 6-<10 years old are the main incidence group, and the prevention and control of infectious diseases in primary schools should be further promoted. Meanwhile, the rapid rise in the incidence of respiratory infectious diseases among people aged 15-19 years old and the increase in the proportion of varicella cases among people aged 10-19 years old suggest that intervention should be carried out to address the influential factors such as immunization gaps and concentrated accommodation in the older age group of minors.
