Objective To study a improved technique by releasing the orbicularis retaining ligament in orbicularis oculi muscle supension blepharoplasty. Release of the orbicularis retaining ligament could cut off the contact between orbitomalar skin and periosteum at inferior orbital rim, and carry the point of tightening orbitomalar skin in orbicularis oculi muscle supension blepharoplasty. Methods There were 409 patients with apparent orbitmalar fold. The methods of releasing orbicularis retaining ligament and orbital septum fixation were added to improve the orbicularis oculi muscle supension blepharoplasty. Results 409 cases were treated using this method over the past 3 years. All results were satisfactory. No complications were observed. Conclusion This improved method of orbicularis oculi muscle supension blepharoplasty is useful for orbitomalar skin rolling, especially for orbitmalar fold. The release allows effective redraping and upward mobilization of the orbicularis of the lower lid and the premalar soft tissues. This method is a simple, safe and effective procedure for the correction of tear trough deformity and well-demarcated lid/cheek junction in lower eyelid belpharoplasty. It is one of the best choices for lower eyelid blepharoplasty.

Objective To evaluate the effects of ultraviolet A (UVA) on autophagy in human skin fibroblasts (HSFs).Methods Cultured HSFs were randomly divided into chronic and acute UVA radiation groups.HSFs in the chronic UVA radiation groups were irradiated with UVA at 5,10 and 20 J/cm2 separately once a day for 4 consecutive days,with HSFs receiving no radiation serving as the chronic radiation control group;HSFs in the acute UVA radiation groups received a single session of radiation with 5,10,30 and 60 J/cm2 UVA separately,with HSFs receiving no radiation serving as the acute radiation control group.After additional culture for different durations,methyl thiazolyl tetrazolium (MTT) assay was performed to evaluate the proliferative activity of HSFs,monodansylcadaverin (MDC) staining to determine autophagy levels,and Western blot analysis to track the conversion of the microtubule-associated protein 1 light chain-3 (LC3)-Ⅰ to LC3-Ⅱ.Statistical analysis was carried out by using one-way analysis of variance followed by Students-Newman-Keuls (SNK) test for multiple-group comparisons and by the independent sample t test for two-group comparisons.Results The cellular proliferative activity significantly decreased in the 3 chronic radiation groups at 1 hour after the final UVA radiation compared with the chronic radiation control group (F =155.5,P ＜ 0.05),and in the 4 acute radiation groups at 1,6 and 12 hours after UVA radiation compared with the acute radiation control group (F =1 335,1 649,2 774,all P ＜ 0.05).MDC staining showed that the autophagy levels in HSFs significantly increased in the 3 chronic radiation groups after UVA radiation compared with the chronic radiation control group (F =748.62,P ＞ 0.05),but showed no significant changes in any of the acute radiation groups at 1,6 or 12 hours after UVA radiation compared with the acute radiation control group (F =0.014,0.004,0.002,all P ＞ 0.05).The ratio of LC3-Ⅱ to LC3-Ⅰ was significantly elevated in all the 3 chronic radiation groups at 1 hour after UVA radiation compared with the chronic radiation control group (t =9.002,21.772,18.33,all P ＜ 0.05),but experienced no obvious changes in any of the acute radiation groups at 1,6 or 12 hours after UVA radiation compared with the acute radiation control group (F =0.13,0.27,0.06,all P ＞ 0.05).Conclusion Chronic UVA radiation can upregulate autophagy levels in HSFs,but acute UVA radiation has no evident effects on it.

Objective To evaluate the effects of alpha-lipoic acid (α-LA)on autophagy in human skin fibroblasts (HSFs). Methods HSFs at passage 3 - 5 were divided into several groups to be cultured with α-LA at final concentrations of 0, 0.01, 0.05, 0.10, 0.15, 0.20 and 0.50 mmol/L for 4, 12 and 24 hours, respectively. Methyl thiazolyl tetrazolium(MTT)assay was performed to evaluate cellular proliferative activity, monodansylcadaverin(MDC)staining to determine autophagy levels, and Western blot to measure the expression of the microtubule-associated protein 1 light chain-3B(LC3-B). Results After incubation for 24 hours, there was a significant difference in the proliferative activity of HSFs among all the groups (F = 10.41, P < 0.05), while no significant differences were observed after incubation for either 4 or 12 hours (F = 2.85, 1.34, respectively, both P > 0.05). MDC staining also showed a significant difference in the percentage of autophagosome-positive cells among all the groups after 24-hour incubation (F = 8.03, P < 0.05), but no significant difference after either 4- or 12-hour incubation (F = 0.11, 0.10, respectively, both P > 0.05). Western blot revealed that the degree of conversion from LC3-Ⅰ to LC3-Ⅱ(LC3-Ⅱ/LC3-Ⅰratio)was significantly different among all the groups after 24-hour incubation (F = 37.49, P < 0.05), but similar after 4- and 12-hour incubation (F = 3.38, 2.13, respectively, both P > 0.05). Conclusion α-LA may inhibit basal autophagy in HSFs.

OBJECTIVETo investigate the effects of small interfering RNA (siRNA) targeting YAP on the proliferation and apoptosis of human periodontal ligament stem cells (hPDLSCs).

METHODSSynthesized sequences of siRNA were transfected into hPDLSCs by Lipofectamine™ 2000. The expression of YAP was identified by using real-time quantitative reverse transcription-polymerase chain reaction (RT-PCR) and Western blot analysis. Proliferation activity was detected by using cell counting kit-8 (CCK-8). Changes in the cell cycle and apoptosis rate were detected by using flow cytometry. Results were analyzed by using SPSS 19.0, and P < 0.05 was considered statistically significant.

RESULTSExpression of YAP mRNA and protein were significantly downregulated after 48 h of transfection (P < 0.001). No obvious difference was found in the expression levels of YAP protein between 48 and 72 h, thus indicating that siRNA could inhibit the expression of YAP persistently and effectively. Proliferation activity was inhibited, and apoptosis rate was increased. Cell cycle was changed as the proportion of G₁and S phases increased (P < 0.01) and G₂ phase decreased (P < 0.05).

CONCLUSIONKnocking down YAP gene by siRNA could inhibit proliferation activity, induce apoptosis, and change the cell cycle of hPDLSCs. Thus, YAP could regulate the proliferation and apoptosis of hPDLSCs.

Abstract On March 12, 2022, a case with Plasmodium vivax malaria was reported in the First Hospital of Jiaxing City. The case sought healthcare services due to persist, sharp distending pain of the brain and fever on February 25, 2022, and the symptoms showed no improvements following symptomatic treatment. Microscopy identified malaria parasites on March 12, and the case was definitively diagnosed as P. vivax malaria on March 13. The case was discharged from hospital on March 16 and relapsed on June 15. The case was a veteran from the China-Myanmar border, where malaria is highly prevalent, and had no history of travel after returning to Jiaxing City on October 2021. Based on epidemiological history and laboratory tests, the case was diagnosed as a cross-border mosquito-borne imported case of P. vivax malaria. The case was given treatment with mosquito vector isolation, and the case's family members, neighbors and colleagues were all tested negative for malaria parasites. There was no Anopheles sinensis detected in the case' residence; however, Anopheles was detected in the neighboring areas, indicating a risk of re-establishment. Returners from high-risk regions including borders and labor exporters are recommended to be included in malaria surveillance, and the sensitivity of malaria surveillance requires to be maintained and the diagnostic and treatment capability of malaria requires to be improved in medical institutions.

Objective:To investigate the effects and underlying mechanisms of phosphoinositide 3-kinase (PI3K)/protein kinase B (AKT)/NF-κB signaling pathway in human kidney-2(HK-2) cells of hyperuricemic nephropathy.Methods:HK-2 cells were cultured in vitro and randomly divided into control group and experimental group. The experimental group was induced by high uric acid (720 μmol/L) immersion for 48 h to establish a cell model of hyperuricemic nephropathy in vitro and subsequently divided into hyperuricemic group, overexpressed protease activated receptor 2 (PAR2) and knockdown PAR2 group. The expressions of PAR2, PI3K, AKT, NF-κB mRNA were measured by real-time PCR. The expressions of PAR2, PI3K, AKT and NF-κB protein were measured by Western blotting. The expressions of tumor necrosis factor-α (TNF-α), monocyte chemotactic protein-1 (MCP-1), interleukin-6 (IL-6), pro-interleukin-1β (pro-IL-1β), interleukin-1β (IL-1β) and transforming growth factor-β1 (TGF-β1) were detected by enzyme linked immunosorbent assay (ELISA). Results:(1) Compared with the control group, the expressions of PAR2, PI3K, AKT and NF-κB mRNA and protein in hyperuricemic group were significantly increased (all P<0.05), the expressions of TNF-α, MCP-1, IL-6, pro-IL-1β, IL-1β and TGF-β1 in the supernatant in hyperuricemic group were significantly increased (all P<0.01). (2) Compared with the hyperuricemic group, the expressions of PAR2, PI3K, AKT and NF-κB mRNA and protein in overexpressed PAR2 group were significantly increased (all P<0.05), the expressions of TNF-α, MCP-1, IL-6, IL-1β and TGF-β1 in the supernatant were significantly increased (all P<0.05). (3) Compared with the hyperuricemic group, the expression of PAR2, PI3K, AKT and NF-κB mRNA and protein in knockdown PAR2 group were significantly decreased (all P<0.05), the expressions of IL-6, pro-IL-1β, IL-1β and TGF-β1 in the supernatant were significantly decreased (all P<0.05). Conclusions:In the process of uric acid-induced HK-2 cell damage, uric acid significantly up-regulates the expression of PI3K/AKT/NF-κB signaling pathway by activating PAR2, leading to a marked increase in inflammatory damage. Knocking down PAR2 inhibits the expression of PI3K/AKT/NF-κB signaling pathway, which can effectively reduce the inflammatory damage of HK-2 cells.
