Abstract Postoperative urinary retention is a common complication after mixed hemorrhoid surgery, referring to the inability of urine in the bladder to be normally expelled, leading to urine retention. This condition not only prolongs the postoperative recovery time and increases medical costs, but may also cause problems such as urinary tract infections and bladder dysfunction. The pathogenesis of urinary retention after mixed hemorrhoid surgery is complex, involving multiple factors such as the type of surgery, anesthesia method, individual differences among patients, postoperative pain management and psychological stress. Although there are various clinical treatment methods, their efficacy varies among individuals. This article reviews relevant literature from 2018 to 2024, analyzing the etiology of urinary retention after mixed hemorrhoid surgery. It summarizes the intervention measures and mechanisms of non-pharmacological treatments, such as physical therapy and analgesic techniques, as well as pharmacological treatments, including anticholinesterase drugs, selective α-receptor blockers and analgesics drugs, so as to provide the reference for the prevention and treatment of urinary retention after mixed hemorrhoid surgery.

AlM:To evaluate the efficacy of combined pranoprofen eye drops and artificial tears on the treatment of mild to moderate dry eye syndrome after trabbeculectomy.METHODS:This prospective case control study included 63 cases (63 eyes) of patients with mild to moderate dry eye syndrome after trabbeculectomy in our hospital from November 2013 to June 2013. All subjects were randomly divided into two groups. Observation group was treated with combined pranoprofen eye drops and artificial tears and control group received simple artificial tears marking the eyes at 1, 2, 4wk. The patient's symptoms, signs, BUT, S▏t, and FL were observed before treatment and 1, 2, 4wk after treatment.RESULTS: After 2wk, the symptoms of observation group were improved, there was statistically significant difference (P<0. 05). FL difference of each group was statistically significant ( P<0. 05 ); After 4wk, symptoms and signs were improved. There was statistically significant difference ( P < 0. 05 ). The BUT of the observation group and corneal FL scores of two groups showed significant differences (P<0. 05). CONCLUSlON: Artificial tears joint pranoprofen eye drops has good curative effect in the treatment of mild to moderate dry eye syndrome after trabbeculectomy.

Objective To assess the effect and feasibility of group reminiscence therapy on depression in the elderly.Methods We searched the Cochrane Central Register of Controlled Trials (-2013),Medline (1982-2013),Embase (1974 2013),AMED (-2013),CINAHL(-2013),CMB (1994-2013),VIP,CNKI and Wanfang to collect the randomized controlled trials (RCTs) in which the group reminiscence therapy was used to treat depression in elderly patients.The studies were selected according to the inclusion and exclusion criteria by two reviewers,and the quality of included studies was evaluated according to Cochrane Handbook and performed meta analyses by using the Cochrane Collaboration's RevMan 5.2 software.Results A total of 10 RCTs involving 944 patients were included.The results of meta-analysis showed that as compared with conventional treatment,group reminiscence therapy on the basis of conventional treatment was more effective in decreasing depression score [MD=-4.86,95 ％ C I(-5.10,-4.65)].Compared with psychological counseling,group reminiscence therapy had more effect on decreasing depression score [MD=-9.34,95％ CI (-10.77,-7.91)].There was no significant difference in the dropout rate between group reminiscence therapy and other control treatments [RR=1.22,95％ CI (0.79-1.88)].The descriptive analysis showed that group reminiscence therapy was effective in alleviating the symptoms of depression.Conclusions Group reminiscence therapy can improve the symptoms of depression in elderly patients and conforms to the principle of economic benefit.However,the results should be interpreted with caution because of the low quality of the included studies.

Objective To investigate the effect of L-selectin in experimental allergic encephalomyelitis (EAE) of Wistar rats.Methods The rats were randomly divided into four groups;the normal group,the CFA group, the LMS group and the model group;The animal models were established in rats by immunization with myelin basic protein of spinal cord of guinea pig and complete Freund's adjuvant(CFA).The symptom of EAE was observed; pathological feature and myelin of brain and spinal were detected with HE stain and Loyez's stain respectively.The number of positive vessels of L-selectin expression was detected by immunohistochemistry.Results 100% experimental Wistar rats treated with MBP and levamisole developed EAE,but none of the other groups.The number of positive vessels of L-selectin expression was (31.86 ± 1.39) in model group, obviously higher than that of in the normal group (1.38 ±0.18) ,the CFA group( 1.50 ±0.27) and the LMS group(7.25 ±0.59) (all P <0.05) ;The inflammation cells were found around vessels and demyelination were seen in white matter of brain and spinal cords.Conclusion The expression of L-selectin should play an important role in EAE.

With the development of drug discovery, more and more candidate compounds need to be studied. Methods that can screen compound rapidly received significant attention. Parallel artificial membrane permeability assay (PAMPA) as a powerful tool has been applied to drug studies. It uses an artificial lipid membrane to mimic the barrier for drug permeability studies. This article introduces the establishment and characteristics of PAMPA, as well as its applications in screening compounds. It can be used as models (e.g. predicting the ability of compound in gastro-intestinal absorption, blood-brain barrier transportation and skin penetration) by changing the component of artificial lipid membrane. PAMPA has advantages in high throughput selection of valuable compound with low cost, versatile, low dose, and good reproducibility.

Objective Our purpose was to investigate the pathogenic gene mutation of a Han Chinese family with vitreous amyloidosis.Methods The 9 individuals(proband,1 affected member and 7 unaffected members) of the family were selected and their DNA was extracted from peripheral blood.The 4 exons of transthyretin(TTR) gene were amplified by polymerase chain reaction(PCR) technique.The amplified products of TTR gene were sequencing by Sanger technique.We also selected 100 unrelated healthy individual as the control group.Results By DNA sequencing,a heterozygous mutation was found in 4 of the 9 subjects from the family.The transition of adenine to cytosine(AAG ＞ ACG) was detectable in exon 2 of TTR,which changed the amino acid composition at codon 35 (Lys35Thr).This mutation did not presented in control group.Conclusion The heterozygosis mutation of TTR gene Lys35Thr should be a pathogenic mutation for the family with vitreous amyloidosis.

Objective To investigate the relationship between the gene polymorphisms of thromboxane A2 receptor (TXA2R) and cerebral infarction. Methods A genetic association study of one single nucleotide polymorphism (rs768963) in the human TXA2R gene was performed in 334 patients with cerebral infarction and 135 healthy controls by polymerase chain reaction-amplification and restriction fragment length polymorphism(PCR-RFLP) method. Results The levels of blood pressure,blood-fat and serum glucose were independent risk factors for cerebral infarction. No significant differences in the overall distribution of genotypes (T/T, T/C and C/C) were noted (P＞0.05); however,significant differences in T or C gene frequency of rs768963 of TXA 2R gene between patients with cerebral infarction and noninfarction controls were found (P＜0.05). Logistic regression analysis showed that no association between the mutant of rs768963 of TXA 2R gene and such factors as gender, age and levels of blood fat, blood pressure and serum glucose was noted. Conclusion The rs768963 of TXA 2R gene in human thromboxane A2 receptor may be a risk factor for cerebral infarction and patients carried C allele are much likely to have cerebral infarction.

1,2,3,4,6-penta-O-galloyl-D-glucose (PGG) is one of the main active compounds of Guizhi Fuling capsule. Molecularly imprinted polymers (MIP) have high affinity toward template molecules synthesized by molecularly imprinted technology for its specific combined sites, which can overcome the shortcoming of traditional separation methods, such as complex operation, low efficiency, using large quantity of solvent and environmental pollution. In this paper, surface molecularly imprinted polymer (SMIP) was prepared by surface imprinting with PGG as the template molecule. Its adsorption capacity was measured by the scatchard equation. The separation of PGG from Guizhi Fuling capsule at preparatived scale was achieved with molecularly imprinted polymer as stationary phase and the purity was 90.2% by HPLC. This method can be used to prepare PGG from Guizhi Fuling capsule with large capacity and is easy to operate. It provides a new method for efficient separation and purification for other natural products.
