The long-acting cabotegravir and rilpivirine injection regimen（CAB+RPV regimen）is the first approved long-acting antiretroviral therapy（ART）for HIV in China，administered once every two months. This regimen provides an innovative alternative to daily oral ART，benefiting virologically suppressed patients. Several large clinical-studies have shown that the CAB+RPV regimen achieves comparable virologic suppression and safety to daily oral regimens，while significantly enhancing patient satisfaction. Based on international and domestic HIV/AIDs guidelines and clinical evidence，this consensus offers expert recommendations on patient selection，clinical management，and key communication strategies for healthcare providers to support the effective use of this regimen，aiming to improve quality of life for people living with HIV and accumulate domestic clinical experience with this advanced treatment approach.

Objective To observe clinical effects of the modified nasopharyngeal airway tube combined with intubation soft lens in endotracheal intubation.Methods Two hundred patients who were to receive surgery were chosen as research subjects.With the knowledge and consent of the patients and following the signing of the letter of agreement,the patients were divided into 4 groups:group A,B,C and D,each consisting of 50 patients.For the patients of group A and B,endotracheal intubation was performed by high-qualified anesthesiologists (with the certificate of medical practitioner for over 5 years),while for the patients of group C and D,intubation was done by low-qualified ones (with the certificate of medical practitioner for less than 5 years).For the patients of group A and C,nasopharyngeal airway tube was placed through the approach of side nasal cavity following anesthesia induction,and then soft lens was used to complete endotracheal intubation via nasopharyngeal airway.For the patients of group B and D,soft lens intubation was performed directly through nasal cavity following anesthesia induction.Medical data,such as intubation time,number of intubation,first time of glottis exposure,cases of intubation failure,and adverse reactions or complications induced by intubation were recorded for further analysis.Results The intubation time of group A was shorter than that of group 13,and the time of group C was shorter than that of group D,and statistical significance could be seen,when comparisons were made between them(P ＜ 0.05).The success rate at the first try of intubation for group A and C were respectively 84％ and 82％,and the failure rate was all 2％,while for group B and D the success rate of intubation were respectively 50％ and 30％,and failure rates were respectively 10％ and 20％.Statistical significance could be noticed,when comparisons were made between the groups,i.e.between group A and B,between group C and D and also between group B and D (P ＜ 0.05).Conclusion Modified nasopharyngeal airway tube combined with intubation soft lens could obviously shorten endotracheal intubation time and increase the success rate of intubation.No significant differences could be noted in intubation time and failure rate,when the use of modified nasopharyngeal airway tube was combined with intubation soft lens by high-qualified and low-qualified anesthesiologists.

Objective To explore the distribution and characteristics of hepatitis B virus (HBV) genotype in the region in Guangxi with high incidence of primary liver cancer (PLC). Methods 103 pairs of samples from the sex- and age-matched members with HBsAg-positive from PLC-clustering families (the experimental group) and carcinoma-free families (control group) were collected. Nested polymerase chain reaction (PCR) and sequencing methods were applied for the analysis of HBV genotype. Results Four HBV genotypes: B, C, B/C and D, were detected, the percentages of them in the two groups were 31.1%, 63.1%, 1.9%, 1.9% and 30.1%, 55.3%, 6.8%, 2.9%, respectively, showed no significant differences (P > 0.05). HBeAg positive rates were significantly different between genotype C and B (P < 0.05), but no significant differences were showed in such factors as gender, age, ethnic group and HBV DNA level in them (P > 0.05). Conclusions The main genotypes were types B and C besides a small number of combined genotypes B/C and D in the regions of Guangxi with a high incidence of PLC. There may be few relationships between HBV genotypes and the high incidence of PLC for familial clustering in Guangxi.

Objective To explore the relationship between mutations in basic core promoter (BCP) of hepatitis B virus (HBV) and familial clustering of hepatocellular carcinoma (HCC) in Guangxi. Methods 153 pairs of members with HBsAg-positive were selected and matched from HCC high-incidence families and carcinoma-free families in Guangxi. The BCP genes were amplified and sequenced. Results The hotspot sites of the previous five mutations in BCP were T1762, A1764, G1775, V1753, G1803. In univariant analysis, HBV DNA≥105 copies/mL, T1762, A1764 and V1753 mutations were associated with the HCC high-incidence (P <0.05). The multivariate logistic analysis showed that HBV DNA≥105 copies/mL and A1764 were independent risk factors for it. Conclusion HBV DNA level, the mutations in BCP showed correlations with familial clustering of HCC in Guangxi.

Objective To investigate the expression of signal transducer and activator of transcription 3 (STAT3) in colorectal car- cinoma tissues and adenomatous polyp tissues, and analyze the relationship between the expression of STAT3 and its clinicopathological pa- rameters in colorectal carcinoma tissues. Methods The protein expressions of STAT3 were detected in 40 colorectal carcinoma tissues, 30 adenomatons polyp tissues and 30 normal colorectal mucosa tissues by MaxVisionTM immunohistochemistry, and the relationship with clinical data were analyzed. Results The STAT3 protein was located mainly in cytoplasm. Positive expression rates of STAT3 protein in colorectal carcinoma tissues, adenomatous polyp tissues and normal colorectal mucosa tissues were 80.0%, 56.7% and 30.0%, respectively. The ex- pression of STAT3 protein in colorectal carcinoma tissues was higher than that in edenomatous polyp tissues (P<0.05 ). Compared with normal colorectal mucosa tissues, the positive expression rates and intensities of STAT3 protein in colorectal carcinoma tissues and adenoma- tous polyp tissues were significantly higher(P<0.05 ) . It was found that overexpreesion of STAT3 protein was related te differentiation, Dukes stage and lymph node metastasis in colorectal carcinoma ( P < 0. 05 ), and no significant differences were found between STAT3 pro- tein expression and other factors such as serosa invasion, distant metastasis , age and gender( P<0.05 ). Conclusions The overexpres- sion of STAT3 protein may play an important role in the genesis and progression of colorectal cancer. In adenomatous polyp tissues, STAT3- positive cells may be potential pre-cancerous cells. Detection of STA'r3 is helpful in accessing the malignant degree and the biological behav- ior of colorectal cancer.
