Background: Viral hepatitis causes annual deaths of 1.4 million people. Antiviral therapy rarely cures the disease, and patients are usually required to maintain lifelong medication, leading to cumulative drug toxicity. Schisandrae Fructus (SF) is efficacious in the treatment of viral hepatitis. Objective: The systematic review and meta-analysis aim to examine the efficacy and safety of SF alone or in combination with specific and nonspecific treatments for treating viral hepatitis by analyzing the clinical trials performed up to date. Methods: An extensive literature was searched in 7 databases from inception to May 2023. Final outcomes were divided into the primary outcomes containing the total effective rate and virological responses, as well as the secondary outcomes containing liver biochemical functions and frequencies of adverse events. RevMan 5.3 and GRADE pro 3.6 software were used for meta-analysis and assessment of evidence quality. Subgroup analysis was conducted to explore the source of the heterogeneity. Results: Twenty-nine randomized controlled trials were included in the meta-analysis. SF treatment was comparable with western medicines or other traditional Chinese treatments in terms of primary and secondary outcomes. In combination with specific treatments with antiviral medicines, SF group reduced 18.45 U/L of alanine aminotransferase levels [weighted mean difference: 18.45, 95% confidence interval (CI): (16.12, 20.78), p < 0.000 01] and 8.37 U/L of aspartate aminotransferase levels [weighted mean difference: 8.37, 95% CI: (1.25, 15.48), p = 0.02], and it decreased the levels of hyaluronic acid (HA) [standard mean difference (SMD): 0.92, 95% CI: (0.58, 1.27), p < 0.000 01], laminin (LN) [SMD: 0.64, 95% CI: (0.38, 0.90), p < 0.000 01], and procollagen type III [SMD: 0.48, 95% CI: (0.28, 0.67), p < 0.000 01], while increasing the total effective rate by 24% [risk ratio: 1.24, 95% CI: (1.15, 1.32), p < 0.000 01]. There were no severe adverse events during treatment. Conclusions: SF was a potential adjuvant for antiviral therapy in restoring liver function. However, the poor quality of the included randomized controlled trials limited the recommendations. More long-term, randomized, and double-blind studies should be performed to assess the efficacy and safety of combination therapy.

Objective:To investigate the treatment strategies for vesicovaginal fistula(VVF)in women following cervical cancer radiotherapy.Methods:A retrospective analysis was performed on the clinical data of 33 female patients with post-radiotherapy VVF after cervical cancer treatment at Shanghai Sixth People’s Hospital between January 2020 and June 2024. The patients were categorized into three groups based on surgical approaches:Group A(11 patients):Underwent prone-position VVF repair. Mean age:(50.0±9.6)years;mean radiotherapy sessions:(22.6±2.2). All had simple VVF without concurrent intestinal or surrounding soft-tissue fistulas. Among them,1 patient previously received laparoscopic VVF repair,1 transvaginal VVF repair,and 2 gracilis muscle flap packing for VVF repair. One month prior to surgery,the average daily usage of urine pads was 16.7(12.8,25.7)pieces,and the quality of life(QOL)score stood at 4.0(4.0,5.0)points. Preoperative cystoscopy revealed that 8 cases had fistulas located in the trigonal region of the bladder,while 3 cases had fistulas on the posterior bladder wall. The diameter of the fistula openings,measured under a microscope,was 1.2(0.8,1.6)cm. Based on the Goh classification criteria for vesicovaginal fistulas,this group included 3 cases of type 1,4 cases of type 2,2 cases of type 3,and 2 cases of type 4;7 cases of type A and 4 cases of type B;as well as 3 cases of typeⅠ,7 cases of type Ⅱ,and 1 case of type Ⅲ.Group B(20 patients):Underwent gracilis muscle flap packing for VVF repair. Mean age:(58.6±8.8)years;mean radiotherapy sessions:(29.8±3.9). Three patients had concurrent rectovaginal fistulas and received colostomy for fecal diversion. History of previous interventions:3 had laparoscopic VVF repair,4 transvaginal VVF repair,and 1 both transvaginal and laparoscopic VVF repair. One month prior to surgery,the average daily usage of urine pads was 19.7(15.8,27.7)pieces,and the QOL score stood at 5.0(5.0,6.0)points. Preoperative cystoscopy revealed that 13 cases had fistulas located in the trigonal region of the bladder,while 7 cases had fistulas on the posterior bladder wall. The diameter of the fistula openings,measured under a microscope,was 1.8(1.0,3.2)cm. Based on the Goh classification criteria for vesicovaginal fistulas,this group included 4 cases of type 1,9 cases of type 2,3 cases of type 3,and 4 cases of type 4;6 cases of type A,11 cases of type B and 3 cases of type C;as well as 1 cases of type Ⅱ,and 19 case of type Ⅲ. Group C(2 patients):Underwent ureterocutaneous diversion. Ages:67 and 73 years;radiotherapy sessions:51 and 60,respectively. Both had concurrent rectovaginal fistulas and bladder soft-tissue fistulas. The patient presented with recurrent thigh abscesses accompanied by fever. One month prior to surgery,the daily usage of urine pads was 29 and 23 pieces,respectively,and the QOL score was 6 points. Cystoscopic examination revealed that the vesicovaginal fistulas were located in the trigone of the bladder,with diameters of 3 cm and 4 cm,respectively. Additionally,partial defects were noted in the ventral wall of the urethra,while no bladder soft tissue fistulas were detected. According to the Goh classification for vesicovaginal fistulas,both cases were categorized as type 4,type C,and type Ⅲ. For Groups A and B,urinary catheters were indwelled for 3 weeks postoperatively,then removed to assess spontaneous urination and incontinence. QOL was evaluated,with a minimum 6-month follow-up. For confirmed postoperative VVF recurrence,re-repair was performed 3?6 months later based on patient preference. For Group C,double-J stents were placed in the ureters,and stoma bags were applied 3 days postoperatively. Stents were replaced every 1?2 months,with QOL assessment. Successful fistula repair in Groups A and B was defined as the absence of vaginal leakage confirmed by cystoscopy after six months of the procedure with no vaginal leakage. For Group C,surgical success was determined by the resolution of perineal urinary leakage and improvement in QOL.Results:All 33 patients completed surgery successfully. Group A:Follow-up duration:16.3(9.6,24.6)months. Surgical repair succeeded in 7 patients,with unobstructed spontaneous urination and no vaginal incontinence. Four patients had VVF recurrence:2 refused further treatment,and 2 underwent repeat gracilis muscle flap packing. One was successfully repaired,while one recurrence case refused further treatment. Group B:Follow-up duration:17.0(9.5,24.8)months(8?32 months). Thirteen patients restored spontaneous urination without recurrence. Seven had recurrence:5 refused further surgery,and 2 underwent re-repair. One repair succeeded without incontinence,while one recurrence case refused treatment. Group C:Follow-up durations were 6 and 22 months. Perineum remained dry without incontinence(no urine pads needed),and no recurrence of thigh soft-tissue redness/infection occurred. QOL scores were 2 and 3,respectively.Conclusions:Post-radiotherapy VVF in women after cervical cancer presents complex and variable conditions. The primary goal of treatment should be to improve patients’ quality of life. Treatment approaches should be selected based on the complexity of urinary fistulas and local tissue conditions. In general,patients who are younger,have received lower doses of radiation therapy,present with smaller fistula diameters,have well-vascularized and elastic perifistular tissues,and have no concurrent tissue fistulas are candidates for prone-position VVF repair. Patients who do not meet the criteria for transvaginal repair,have a history of at least two previous repair attempts,or have concurrent vaginorectal fistulas require gracilis muscle flap packing for VVF repair. Patients with three or more types of concurrent tissue fistulas,extensive pale and inelastic perifistular tissues,and who are not amenable to repair surgery undergo ureterocutaneous diversion.

Various dynasties of herbs and prescription books recorded the specifications, processing, and clinical application of Schisandrae Chinensis Fructus. The clinical application of Schisandrae Chinensis Fructus mainly focuses on astringency, tonifying qi and generating fluids, nourishing the kidneys and calming the heart. There have been few reports on the exploration on textual study on other functions and usage precautions of Schisandrae Chinensis Fructus; at present, the classic prescriptions containing Schisandrae Chinensis Fructus do not clearly indicate their specific specifications and processing in the prescription composition. Textual study has found that different processed products of Schisandrae Chinensis Fructus have different clinical therapeutic effects. For raw use, it is more suitable to use light agents to bring adversely risen qi downward, steam to produce light agents to increase transparency, honey to produce leveling agents is better for moistening the lungs and nourishing yin, wine honey to produce leveling agents can supplement deficiency and promote blood circulation, wine to produce heavy agents can strengthen acid absorption. It is suggested further in-depth research on steamed products, honey products, and honey wine products to broaden clinical application options and improve the accuracy of clinical medication. The clinical application of Schisandrae Chinensis Fructus has different emphases and evolution in different dynasties. In the Tang Dynasty, Schisandrae Chinensis Fructus could reduce the qi of the upper, middle, and lower energizers, and eliminate deficiency heat; during the Five Dynasties period, Schisandrae Chinensis Fructus could nourish qi, improve eyesight, warm the middle, and bring adversely risen qi downward; During the Jin and Yuan dynasties, Schisandrae Chinensis Fructus was used to warm water and treat cholera, as well as to improve muscle function; in the Ming Dynasty, Schisandrae Chinensis Fructus was proposed to reduce qi and strengthen yin, treating the critical condition of yin and yang deficiency; during the Qing Dynasty, Schisandrae Chinensis Fructus could prevent summer heat, and external application to sores could astringent and invigorate the muscles. Schisandrae Sphenantherae Fructus has records of dispersing phlegm and fire, and dispelling wind pathogens. This article reviewed the relevant records of Schisandrae Chinensis Fructus in traditional Chinese herbs and prescriptions throughout history, summarized the efficacy characteristics of Schisandrae Chinensis Fructus under different processing methods, clinical applications under historical evolution, and main contraindications for use, proposed recommendations for the application of Schisandrae Chinensis Fructus in classic and commonly used prescriptions, which can provide scientific basis for the precise selection of different specifications and processed products of Schisandrae Chinensis Fructus and Schisandrae Sphenantherae Fructus, as well as scientific guidance for their rational application in drug development.

A valid, novel, and comprehensive evaluation method for assessing the quality of Magnolia officinalis leaves (MOLs) from different origins has been established based on multiwavelength fusion fingerprint, quantitative analysis, and antioxidant activity screening. The four wavelength fingerprints for MOL samples at 258, 266, 290, and 327 nm were collected by high performance liquid chromatography, and then data fusion was conducted. In addition, the content of multiple components was determined by high performance liquid chromatography at four wavelengths. 1, 1-Diphenyl-2-pyridyl hydrazine scavenging assay was applied to study in vitro antioxidant activity. The effective distinction of 18 batches of MOLs was realized based on hierarchical cluster analysis, principal component analysis, and orthogonal partial least squares discriminant analysis combined with multiwavelength fusion fingerprint. The orthogonal partial least squares discriminant analysis model exhibited huge advantages in distinguishing among different samples and screening three quality markers of the tested samples, including rutin, isoquercitrin, and chlorogenic acid. This established method of multitechnology fusion is simple, reliable, and efficient for the qualitative and quantitative bioactivity evaluation of MOLs. This study aims to investigate the development of new medicinal parts of traditional Chinese medicines (TCMs), so as to enhance the efficiency of utilizing TCM resources and promote the high-quality development of the TCM industry.
