Background: Postherpetic neuralgia(PHN) is the most common complication of herpes zoster infection and affects patients' quality of life. Acupuncture therapy is regarded as a competitive method of treatment for analgesia. Objective: To summarize evidence from systematic reviews(SRs) and evaluate the effectiveness and safety of different acupuncture therapies for treating PHN. Methods: Eight electronic databases were searched from their inception to August 5, 2022, including 4 international electronic databases(PubMed, EMBASE, the Cochrane Library, and Web of Science) and 4 Chinese databases(Chinese Biomedical Database, China National Knowledge Infrastructure, VIP Database and Wanfang Database).Methodological quality was assessed by A Measurement Tool to Assess Systematic Reviews 2(AMSTAR 2).The Risk of Bias in Systematic Review(ROBIS) tool was used to assess the risk of bias in SRs. Evidence level was assessed by the Grading of Recommendations Assessment, Development, and Evaluation(GRADE)approach. Results: Totally, 7 SRs were included, including 128 studies and 9,792 patients. In AMSTAR 2, most of the SRs were of low or critically low levels since they had more than 1 critical deficiency. In ROBIS, 1 SR(14.29%)was rated as high risk, and the other 6(85.71%) were rated as low risk. In the GRADE system, 9 outcomes(28.13%)were valued as high level, 5(15.63%) as moderate level, 1(3.13%) as low, and 17(53.13%) as very low. In the effectiveness of acupuncture therapy, the group "moxibustion vs. original medical treatment" [mean difference(MD)=–1.44, 95% confidence interval(CI): –1.80 to –1.08, I2=99%, P<0.00001] was of the highest heterogeneity and the group "bloodletting vs. original medical treatment"(MD=–2.80, 95% CI: –3.14 to –2.46, I2=0, P<0.00001)was of the lowest heterogeneity. Six SRs have reported the safety of their studies and no serious events were shown in the treatment and control groups. Conclusions: Acupuncture therapy seems to be effective in treating PH

The preparation of nanometer γ-Fe2O3 through an electrochemical process was studied at room temperature, using a metal iron plate as sacrificing anode and a sheet of stainless steel as cathode, in non-aqueous mediate containing （Bu）4 NBr as support electrolyre and 2% （vol%） water. The powdery particles obtained were then calcined at 300 ℃. The products were characterized by IR, XRD, SEM, TEM and laser particle size analyser, indicating the fine particle is a pure nanometer γ-Fe2O3. The morphology is like coneshaped and their average size is 22.0 nm. Furthermore the VSM spectrum shows that the particle＇s coercivity （3.9 × 10^3 A/m） is rather small, presenting the excellent super-paramagnetism.

AIM:To test the effect of autophagy on inflammatory damage resulting from oxidative stress in adult retinal pigment epithelial cell line(ARPE-19).METHODS:ARPE-19 cells were pretreated with 200 and 600μmol/L hydrogen peroxide(H_(2)O_(2))at various time *** changes of cell morphology,cell viability,reactive oxygen species(ROS)level,autophagic activity,and the inflammatory cytokines(TNFα,IL-6,and TGFβ)were measured at baseline and after treatment with autophagy inducer rapamycin(Rapa)and suppressor wortmannin(Wort)or ***:The levels of ROS,cytokines(TNFα,IL-6,and TGFβ),and autophagic activity were significantly increased in ARPE-19 cells after pretreated with H2O2(all P<0.05)and IL-10 was significantly decreased(P<0.05).By upregulating autophagy,Rapa significantly reduced oxidative stress-induced secretion of pro-inflammatory factors(TNFα and IL-6)and ROS(all P<0.05),yet elevated the production of TGFβ(P<0.05).In contrast,suppression of autophagy through Wort or ATG5 knockdown reduced cell viability,increased cell apoptotic rate,and exacerbated the generation of ROS and inflammatory cytokines(TNFα,IL-6,and TGFβ;all P<0.05).CONCLUSION:Autophagy demonstrates a protective effect on ARPE-19 cell through mitigating oxidative damage and oxidative stress-induced inflammatory *** of autophagy may be a potential way for agerelated macular degeneration.

The suddenness, uncertainty, and randomness of rockbursts directly affect the safety of tunnel construction. The prediction of rockbursts is a fundamental aspect of mitigating or even eliminating rockburst hazards. To address the shortcomings of the current rockburst prediction models, which have a limited number of samples and rely on manual test results as the majority of their input features, this paper proposes rockburst prediction models based on multi-featured drilling parameters of rock drilling jumbo. Firstly, four original drilling parameters, namely hammer pressure (Ph), feed pressure (Pf), rotation pressure (Pr), and feed speed (VP), together with the rockburst grades, were collected from 1093 rockburst cases. Then, a feature expansion investigation was performed based on the four original drilling parameters to establish a drilling parameter feature system and a rockburst prediction database containing 42 features. Furthermore, rockburst prediction models based on multi-featured drilling parameters were developed using the extreme tree (ET) algorithm and Bayesian optimization. The models take drilling parameters as input parameters and rockburst grades as output parameters. The effects of Bayesian optimization and the number of drilling parameter features on the model performance were analyzed using the accuracy, precision, recall and F1 value of the prediction set as the model performance evaluation indices. The results show that the Bayesian optimized model with 42 drilling parameter features as inputs performs best, with an accuracy of 91.89%. Finally, the reliability of the models was validated through field tests.
