In the process of seeking new strategies to improve the efficacy of antidepressants,traditional Chinese medicine inter-vention has gradually revealed its unique prevention and treat-ment advantages.The dopamine reward system is closely in-volved in the pathological occurrence and development of depres-sion.Currently,research has mostly focused on the functional mechanism of a specific nucleus in the dopamine reward system,and there is less research focused on the functional mechanism of the neural circuit.In the current micro research on reward cir-cuits,the association between abnormal reward circuits and neg-ative emotions such as anxiety and depression has been widely recognized.Traditional Chinese medicine intervention can exert antidepressant effects by influencing reward circuits.This article provides a review on the loop mechanism of dopamine reward system involvement in depression and research on traditional Chinese medicine intervention.

Objective:To explore the effects of hypoxia on traumatic brain swelling (TBS) in rats with acute subdural hematoma (ASDH).Methods:Forty-five SD rats were divided into 5 groups according to the random number table method, with 9 rats in each group: sham surgery normal oxygen group which underwent sham surgical procedures and were placed in a closed container with ventilation, sham surgery hypoxia group which underwent sham surgical procedures and were placed in a closed container with oxygen volume fraction of 8% for hypoxia induction, ASDH normal oxygen group which made into the ASDH model and placed in a closed container with ventilation, ASDH hypoxia group were made into the ASDH models and placed in a closed container with oxygen volume fraction of 8% for hypoxia induction, and ASDH hypoxia+oxygen inhalation group which inhaled oxygen continuously with oxygen volume fraction of 40% after being made into the ASDH models and induced for hypoxia. Six rats were selected from each group immediately after the modeling and craniotomy was performed to observe the brain swelling during the surgery and evaluate the degree of TBS. Microvascular blood flow was observed by laser speckle imaging system before modeling, before craniotomy, and immediately after craniotomy. The remaining 3 rats in each group were killed directly after modeling and brain tissue specimens were collected. The expression levels of pericellular protein α-smooth muscle actin (α-SMA) and platelet-derived growth factor receptor-β (PDGFR-β) at 0, 30 and 60 minutes after modeling were detected through Western blot analysis. The expression levels of α-SMA, PDGFR-β and microvascular marker platelet-endothelial cell adhesion molecule 31 (CD31) at 0 minute after modeling were tested through immunofluorescent staining.Results:No brain bulge was observed in the sham surgery normal oxygen group. The height of brain bulge in sham surgery hypoxia group was 0.5(0.0, 1.0)mm, with no significant difference from that in the sham surgery normal oxygen group ( P>0.05); it was 2.2(2, 2.5)mm in the ASDH normal oxygen group, significantly higher than that in the sham surgery normal oxygen group and sham surgery hypoxia group ( P<0.01), it was 3.1(2.9, 3.2)mm in the ASDH hypoxia group, significantly higher than that in the sham surgery normal oxygen group, sham surgery hypoxia group and ASDH normal oxygen group ( P<0.01); it was 2.8(2.7, 2.9)mm in the ASDH hypoxia+oxygen inhalation group, not statistically different from that in the ASDH hypoxia group ( P>0.05), but significantly increased compared with that in the sham surgery normal oxygen group, sham surgery hypoxia group and ASDH normal oxygen group ( P<0.01). Before modeling, before craniotomy and after craniotomy, the microvascular blood flow was 224.2±49.7, 224.8±50.3, 225.1±50.3 respectively in the sham surgery normal oxygen group and 224.7±43.7, 220.9±45.9, 221.8±45.5 respectively in the sham surgery hypoxia group, with no significant difference between the two groups ( P>0.05); it was 226.5±52.7, 173.4±40.7, 172.0±40.7 respectively in the ASDH normal oxygen group, significantly decreased compared with that in the sham surgery normal oxygen group and sham surgery hypoxia group ( P<0.05); it was 225.7±46.4, 131.4±23.6 and 131.0±23.5 respectively in the ASDH hypoxia group, significantly decreased compared with that in the sham surgery normal oxygen group, sham surgery hypoxia group and ASDH normal oxygen group ( P<0.05); it was 226.2±56.1, 132.6±21.7 and 131.7±21.9 respectively in ASDH hypoxia+oxygen inhalation group, significantly decreased compared with that in the sham surgery normal oxygen group, sham surgery hypoxia group and ASDH normal oxygen group ( P<0.05), with no significant difference from that in the ASDH hypoxia group ( P>0.05). At 0, 30 and 60 minutes after modeling, the expression levels of α-SMA and PDGFR-β were 0.70±0.02, 0.67±0.01, 0.55±0.05 and 0.65±0.03, 0.56±0.03 and 0.59±0.02 respectively in the sham surgery normal oxygen group and were 0.63±0.04, 0.60±0.01 0.55±0.05 and 0.62±0.01, 0.51±0.01 and 0.60±0.02 respectively in the sham surgery hypoxia group, with no significant difference between the two groups ( P>0.05); they were 0.88±0.06, 0.87±0.05, 0.82±0.03 and 0.85±0.03, 0.85±0.03, 0.88±0.04 respectively in the ASDH normal oxygen group, significantly higher than those in the sham surgery normal oxygen group and sham surgery hypoxia group ( P<0.01); they were 1.19±0.08, 1.10±0.10, 0.97±0.04 and 1.04±0.06, 1.19±0.07, 1.27±0.08 respectively in the ASDH hypoxia group, significantly higher than those in sham surgery normal oxygen group, sham surgery hypoxia group and ASDH normal oxygen group ( P<0.05 or 0.01); they were 1.20±0.07, 1.10±0.04, 0.96±0.04 and 1.04±0.05, 1.15±0.11, 1.20±0.07 respectively in ASDH hypoxia+oxygen inhalation group, significantly higher than those in sham surgery normal oxygen group, sham surgery normal group and ASDH normal oxygen group ( P<0.01), but with no significant difference from those in ASDH hypoxia group ( P>0.05). At 0 minute after modeling, the fluorescence expression of α-SMA and PDGFR-β was weaker in the sham surgery normal oxygen group and the fluorescence expression of CD31 was stronger. There was no significant difference in the fluorescence expressions of α-SMA, PDGFR-β and CD31 between the sham surgery hypoxia group and sham surgery normal oxygen group. The fluorescence expressions of α-SMA and PDGFR-β in the ASDH normal oxygen group were stronger than those in the sham surgery normal oxygen group and sham surgery hypoxia group, while the fluorescence expression of CD31 was weaker. The fluorescence expressions of α-SMA and PDGFR-β in ASDH hypoxia group were stronger than those in the sham surgery normal oxygen group, sham surgery hypoxia group and ASDH normal oxygen group, while the fluorescence expression of CD31 was weaker. The fluorescence expressions of α-SMA and PDGFR-β in the ASDH hypoxia+oxygen inhalation group were stronger than those in the sham surgery normal oxygen group, sham surgery hypoxia group and ASDH normal oxygen group, while the fluorescence expression of CD31 was weaker, with no significant difference from the fluorescence expressions of α-SMA, PDGFR-β and CD31 in ASDH hypoxia group. Conclusions:Hypoxia in ASDH rats will stimulate pericytes contraction, which causes cerebral microcirculatory disturbance, thus leading to TBS. Short-term inhalation of oxygen of medium concentration cannot dilate pericytes or microcirculation vessels, with no obvious effect on improving the conditions of TBS.

Objective To analyze the genetic subtypes of human immunodeficiency virus (HIV) and the prevalence of pretreatment drug resistance in the newly reported HIV-infected men in Guangxi. Methods The stratified random sampling method was employed to select the newly reported HIV-infected men aged≥50 years old in 14 cities of Guangxi from January to June in 2020.The pol gene of HIV-1 was amplified by nested reverse transcription polymerase chain reaction and then sequenced.The mutation sites associated with drug resistance and the degree of drug resistance were then analyzed. Results A total of 615 HIV-infected men were included in the study.The genetic subtypes of CRF01_AE,CRF07_BC,and CRF08_BC accounted for 57.4% (353/615),17.1% (105/615),and 22.4% (138/615),respectively.The mutations associated with the resistance to nucleoside reverse transcriptase inhibitors (NRTI),non-nucleoside reverse transcriptase inhibitors (NNRTI),and protease inhibitors occurred in 8 (1.3%),18 (2.9%),and 0 patients,respectively.M184V (0.7%) and K103N (1.8%) were the mutations with the highest occurrence rates for the resistance to NRTIs and NNRTIs,respectively.Twenty-two (3.6%) patients were resistant to at least one type of inhibitors.Specifically,4 (0.7%),14 (2.3%),4 (0.7%),and 0 patients were resistant to NRTIs,NNRTIs,both NRTIs and NNRTIs,and protease inhibitors,respectively.The pretreatment resistance to NNRTIs had much higher frequency than that to NRTIs (2.9% vs.1.3%;χ2=3.929,P=0.047).The prevalence of pretreatment resistance to lamivudine,zidovudine,tenofovir,abacavir,rilpivirine,efavirenz,nevirapine,and lopinavir/ritonavir was 0.8%, 0.3%, 0.7%, 1.0%, 1.3%, 2.8%, 2.9%, and 0, respectively. Conclusions CRF01_AE,CRF07_BC,and CRF08_BC are the three major strains of HIV-infected men≥50 years old newly reported in Guangxi,2020,and the pretreatment drug resistance demonstrates low prevalence.
