The combined application of ear acupuncture in the treatment of allergic rhinitis: A meta-analysis

Objective

Meta-analysis was used to evaluate the clinical efficacy of auricular acupressure in the treatment of allergic rhinitis.

Methods

Randomised controlled trials (RCTS) on the treatment of allergic rhinitis with ear acupuncture were searched by computer in PubMed, Cochrane Library, Embase、Web of Science、China National Knowledge Infrastructure (CNKI), Wanfang Database (Wanfang), VIP database, and China Biomedical Literature Service System (CBM). The search time was from the establishment of the database to September 18, 2022. Meta-analysis was performed using RevMan 5.4 software.

Results

A total of 15 papers with 1002 patients were included in the final study. ①Clinical efficiency: The clinical efficiency of ear acupuncture combined with control group was higher than that of control group, and the difference was statistically significant (P < 0.00001); ② Nasal symptom score: the effect of ear acupuncture combined with control group on allergic rhinitis on nasal symptoms was more obvious than that of control group, and the difference was statistically significant (P = 0.004); ③ Nasal itching symptom score: the efficacy of ear acupuncture combined with control group on allergic rhinitis on nasal itching symptom was significantly higher than that of control group, and the difference was statistically significant (P = 0.01). ④Sneeze symptom score: the effect of ear acupuncture combined with control group on allergic rhinitis on nasal itching symptom was more effective than that of control group, and the difference was statistically significant (P < 0.00001); ⑤Score of runny nose symptom: the effect of ear acupuncture combined with control group on allergic rhinitis on runny nose symptom was more obvious than that of control group, the difference was statistically significant (P = 0.004); ⑥Nasal congestion symptom scores: The effect of ear acupuncture combined with control group on allergic rhinitis on nasal congestion symptom was more obvious than that of control group, and the difference was statistically significant (P = 0.003). Conclusion: Ear acupuncture as an adjunctive therapy of allergic rhinitis can achieve better clinical efficacy.

Effects of microbial inoculant and additives on pile composting of cow manure

Composting is an effective method of recycling organic solid waste, and it is the key process linking planting with recycling. To explore the reuse of agricultural organic solid waste as a resource in the Yellow River Delta, the effects of microbial inoculant and different additives (calcium superphosphate, biochar, tomato straw, rice husk, and sugar residue) on pile composting of cow dung were studied to obtain the best composting conditions. The results showed that microbial inoculant and additives all played positive roles in the process of aerobic composting, and the experimental groups outperformed the control groups without any additives. For discussion, the microbial inoculant promoted rapid pile body heating more than the recovery materials alone, and the effects on aerobic composting were related to the organic matter of substrates and biochar. After being composted, all the materials were satisfactorily decomposed. Degradation of additives into humic acid might serve as electron shuttles to promote thorough organic matter decomposition. These results provide a scientific basis data for industrial composting of organic solid waste processed by on-site stacking, and provide a reference for researcher and practitioners for studying the applications of microbial inoculant on aerobic composting.

[Study and evaluation of preparation of silybin PLGA microspheres by stainless steel membrane emulsification technique]

OBJECTIVE

The aim of the present study was to prepare uniform-sized silybin loaded poly (lactic-co-glycolic acid) (PLGA) microspheres in study of silybin with stainless steel membrane.

METHOD

Silybin PLGA microspheres were prepared by stainless steel membrane emulsification. The preparation conditions were optimized by single-factor test and orthogonal experiment, and evaluating the mean diameters, the particle size distribution, drug loading, entrapment efficiency and morphology of microsphere.

RESULT

Prepared microspheres were round and surface was smooth. The mean diameter was (4.961 +/- 0.56) microm. The span was (1.75 +/- 0.18). The entrapment efficiency was (54.997 +/- 4.05)% and the average drug loading was (23.6 +/- 1.70)%.

CONCLUSION

The stainless steel membrane emulsification can be used to prepare the silybin PLGA microspheres. The mean diameters of the silybin PLGA microspheres can be controlled in certain level. Stainless steel membrane emulsification has great potentiality exploitation and utilization.

[Production and identification of anti-paraoxon monoclonal antibodies]

Paraoxon (E600) was conjugated to bovine serum albumin(BSA) or tachypleus tridentatus hemocyanin (TTH) by diazotization. Two hybridoma cell lines secreting monoclonal antibodies(McAb) against paraoxon have been established by fusing mouse myeloma cells and splenocytes from Balb/c mice immunized with E600-BSA. The chromosomes of the hybridoma cell 2B10 were analyzed. The immunoglobulin of the McAb was classified. The affinity and specificity of this antibody were determined. The hybridoma cells have fairly reserved the antibody-producing capacity after continuously growing or stored in liquid nitrogen for 10 weeks.

[Injury to urinary system in the operation of gynecology]

OBJECTIVE

To reduce the incidence of urinary system injury from gynecology operations.

METHODS

26 cases with urinary system injuries during gynecological operations were analyzed from 1982 to 1996.

RESULTS

The incidence of urinary injury in this hospital was 0.34%, and injuries occurred most frequently in the bladder. Among the 17 cases of bladder injuries, 12 occurred during tubal ligation, 3 during cesarean section, and 2 in myomectomy. There were 9 cases of ureter injuries, 6 cases occurred in radical hysterectomy for cervical cancer, 1 in cesarean section with hysterectomy, and 2 in hysterectomy with broad ligament leiomyoma.

CONCLUSIONS

This study demonstrated that it was important to be familiar with the regional anatomy, to operate strictly and separate those organs carefully in preventing the urinary system injury.

[A comparison between diltiazem SR and diltiazem HCL in the treatment of angina pectoris]

This study included 168 patients with angina pectoris, who were divided into two groups, the diltiazem SR (No. 88) group and diltiazem HCL (No. 80) group. The two groups were comparable in age and duration of coronary heart disease. The results were as follows: (1) The total clinical effect of diltiazem SR (94.3%) was slightly greater than that of diltiazem HCL (82.5%), the effect in ECG improvement was 53.3% and 53.4% respectively. (2) The rate of adverse effect was 12.5% in diltiazem SR group and 14.4% in diltiazem HCL group. It is concluded that the two different types of diltiazem have similar effect in the treatment of angina pectoris. However, it is more convenient to take diltiazem SR than diltiazem HCL as the former needs only twice a day.
