Objective]The article summarizes the clinical experience of CHB by professor Wang Bangcai, the famous Zhejiang TCM physician. [Methods] From following professor Wang Bangcai clinical studies, summarize the experience and thoughts of treating CHB, and for two cases. [Results] Professor Wang Bangcai thinks the cause of CHB is the incubated epidemic pathogenic factor inside the body and the invasion of exogenous pathogenic factors. Its main pathogenesis is the insufficiency of healthy qi and the excess of exogenous pathogens. Insufficiency of healthy qi is the essential factor, while the accumulation of incubated epidemic pathogen and the disorder of liver and spleen is the subordinate factor. The course of the disease is generally long, the fight between healthy qi and pathogenic factors is always prolonged, and the insufficiency of healthy qi and the excess of exogenous pathogens usually both exist. Professor Wang emphasizes that strengthening healthy qi, eliminating pathogenic factors and regulating liver and spleen to comply with their nature characters are very important in order to defeat the incubated epidemic pathogen, as well as eliminating toxin inside the body and dispersing stagnant pathogens. The following two cases both have remarkable curative results. [Conclusion]Professor Wang Bangcai has original views on CHB about the etiology,pathogenesis and syndrome differentiation,which is worthy of in-depth study and understanding.

Objective:To investigate the clinical efficacy of a 1 064 nm picosecond laser combined with intense pulsed light in the treatment of melasma.Methods:From May to August 2022, ninety-two female patients with melasma were admitted to the Medical Cosmetology Center, Xi′an International Medical Center Hospital, aged 25-50 years, with an average age of (35.0±3.5) years. The were divided by random number table method. Forty-six cases were divided into laser combined group, which were treated with precise intense pulsed light combined with a 1 064 nm picosecond laser. Forty-six cases in the laser group were treated with a 1 064 nm picosecond laser. The area and severity score of melasma (MASI), VISIA score and clinical efficacy were evaluated.Results:The MASI scores of laser combined group were 12.58 (11.04, 13.99) before treatment, and the MASI scores of laser group were 13.16 (11.47, 14.14) before treatment. The MASI scores of laser combined group were 5.75 (3.79, 7.19), and the MASI scores of laser group were 7.15 (5.42, 5.85) after treatment. The MASI scores of the two groups were decreased compared with those before treatment, and the MASI score of the laser combined group was lower than that of the laser group. The difference was statistically significant ( Z=-4.05, P<0.01). The median VISIA scores of the laser combined group were (173.72±43.77), and the median VISIA scores of the laser group were (175.65±34.9) before treatment. The median VISIA scores of the laser combined group were (135.46±41.63), and the median VISIA scores ofthe laser group were (145.26±33.33) after treatment. The VISIA scores of the two groups were decreased compared with those before treatment. The scores of the laser combined group were lower than those of the laser group. The difference was statistically significant ( t=-2.52, P<0.05). The effective rate of the laser combined group (80.43%, 37/46) was higher than that of the laser group (69.56%, 22/46, P<0.05). Conclusions:The curative effect of 1 064 nm picosecond laser combined with precise intense pulsed light in the treatment of melasma is better than that of a 1 064 nm picosecond laser alone.

Objective:Evaluation of the efficacy and safety of ultra-picosecond 1 064 nm laser treatment for enlarged facial pores.Methods:From November 2022 to April 2023, 31 female patients with enlarged facial pores, aged between 28 and 52 (35.2±5.5) years old, were treated at the Medical Aesthetics Center of Xi′an International Medical Center Hospital. They received ultra-picosecond 1 064 nm laser fractional handpiece treatment once every 4 weeks for a total of 3 times. One month after the last treatment, facial pore changes were evaluated using facial pore scores and VISIA pore feature count absolute values, and adverse reactions were assessed.Results:All 31 patients completed the treatment. The facial pore scores before and after treatment were 4 (4, 5) and 2 (2, 3), respectively, indicating a statistically significant ( Z=-4.99, P<0.001) decrease in facial pore scores compared to before treatment. The absolute values of VISIA facial pore counts before and after treatment were 859 (829, 1147) and 652 (632, 731), respectively. The absolute value of VISIA pore count after treatment was lower than that before treatment, and the difference was statistically significant ( Z=-4.86, P<0.05 ). Conclusions:Ultra-picosecond laser can effectively improve enlarged facial pores without significant adverse reactions.

Excavating the quantitative trait locus (QTL) associated with rice cooking quality, analyzing candidate genes, and improving cooking quality-associated traits of rice varieties by genetic breeding can effectively improve the taste of rice. In this study, we used the indica rice HZ, the japonica rice Nekken2 and 120 recombinant inbred lines (RILs) populations constructed from them as experimental materials to measure the gelatinization temperature (GT), gel consistency (GC) and amylose content (AC) of rice at the maturity stage. We combined the high-density genetic map for QTL mapping. A total of 26 QTLs associated with rice cooking quality (1 QTL associated with GT, 13 QTLs associated with GC, and 12 QTLs associated with AC) were detected, among which the highest likelihood of odd (LOD) value reached 30.24. The expression levels of candidate genes in the localization interval were analyzed by quantitative real-time polymerase chain reaction (qRT-PCR), and it was found that the expression levels of six genes were significantly different from that in parents. It was speculated that the high expression of LOC_Os04g20270 and LOC_Os11g40100 may greatly increase the GC of rice, while the high expression of LOC_Os01g04920 and LOC_Os02g17500 and the low expression of LOC_Os03g02650 and LOC_Os05g25840 may reduce the AC. The results lay a molecular foundation for the cultivation of new high-quality rice varieties, and provide important genetic resources for revealing the molecular regulation mechanism of rice cooking quality.

Neurogenesis decline in hippocampal dentate gyrus (DG) participates in stress-induced depressive-like behaviors, but the underlying mechanism remains poorly understood. Here, we observed low-expression of NOD-like receptor family pyrin domain containing 6 (NLRP6) in hippocampus of stress-stimulated mice, being consistent with high corticosterone level. NLRP6 was found to be abundantly expressed in neural stem cells (NSCs) of DG. Both Nlrp6 knockout (Nlrp6^-/-) and NSC-conditional Nlrp6 knockout (Nlrp6CKO) mice were susceptible to stress, being more likely to develop depressive-like behaviors. Interestingly, NLRP6 was required for NSC proliferation in sustaining hippocampal neurogenesis and reinforcing stress resilience during growing up. Nlrp6 deficiency promoted esophageal cancer-related gene 4 (ECRG4) expression and caused mitochondrial dysfunction. Corticosterone as a stress factor significantly down-regulated NLRP6 expression, damaged mitochondrial function and suppressed cell proliferation in NSCs, which were blocked by Nlrp6 overexpression. ECRG4 knockdown reversed corticosterone-induced NSC mitochondrial function and cell proliferation disorders. Pioglitazone, a well-known clinical drug, up-regulated NLRP6 expression to inhibit ECRG4 expression in its protection against corticosterone-induced NSC mitochondrial dysfunction and proliferation restriction. In conclusion, this study demonstrates that NLRP6 is essential to maintain mitochondrial homeostasis and proliferation in NSCs, and identifies NLRP6 as a promising therapeutic target for hippocampal neurogenesis decline linked to depression.
