[Clinical observational study on the treatment of oligozoospermia with Shizi Sanhua decoction combined with Nuoyu]

OBJECTIVE

To study the clinical therapeutic effect as well as drug effectiveness and safety of Shizi Sanhua decoction combined with Nuoyu in the treatment of oligozoospermia in men.

METHODS

102 patients with oligozoospermia diagnosed at Longhua Hospital of Shanghai University of Traditional Chinese Medicine from February 2022 to March 2023 were selected and randomly divided into 3 groups. The treatment group was treated with Shizi Sanhua Decoction + Nuoyu; the traditional Chinese medicine group was treated with Shizi Sanhua Decoction; and the Nuoyu nutrient group was treated with Nuoyu nutrient. A review assessment and record were made after one course of treatment (3 months).

RESULTS

A total of 102 patients completed the trial due to the treatment process. There were 34 cases in each of the traditional Chinese medicine group, the Nuoyu nutrient group, and the treatment group. Clinical efficacy: total effective rate of 52.94% in the traditional Chinese medicine group; 58.82% in the Nuoyu nutrient group; 82.35% in the treatment group. The clinical efficacy of the treatment group was better than that of the traditional Chinese medicine group and the Nuoyu nutrient group (P<0.05), which was statistically significant. Semen routine: the treatment group was better than the traditional Chinese medicine group and Nuoyu nutrient group in improving the total number of sperm and sperm concentration.

CONCLUSION

The semen concentration and forward sperm count of patients with oligozoospermia treated with Shizi Sanhua Decoction combined with Nuoyu improved more significantly, and the clinical efficacy was remarkable. And the clinical efficacy is not affected by age and disease duration. It can be popularized and applied as a treatment for oligozoospermia.

[Clinical value of (125)I radioactive seed implantation plus transcatheter arterial chemoembolization combined with radiofrequency ablation in treating patient with sub-capsular hepatocellular carcinoma]

Objective: To analyze the clinical efficacy and safety of (125)I radioactive seed implantation in the treatment of sub-capsular hepatocellular carcinoma (sub-HCC) with sequential radiofrequency ablation and transcatheter arterial chemoembolization (TACE). Methods: The clinical data of 76 cases with advanced HCC with sub-capsular nodules including 68 males and 8 females, with an average age of (58±9) years, ranging from 33 to 78 years, enrolled in Lishui Central Hospital from January 2010 to December 2016 were collected.The average maximum diameter of tumor is (5.7±2.3) cm, ranging from 3.1 cm to 12.0 cm.The patients were divided into TACE+ RFA group and (125)I + TACE+ RFA group with 38 cases in each group.The overall survival (OS) and progression free survival(PFS) were calculated.The clinical efficiency and adverse events were evaluated. Results: The disease control rate were 84.2%(32/38) in (125)I + TACE+ RFA group and 63.2% (24/38) in TACE+ RFA group, χ(2)=4.34, P= 0.04.The median PFS were 18 months in (125)I + TACE+ RFA group and 11 months in TACE+ RFA group, χ(2)=4.84, P=0.03.The FPS cumulative rate in (125)I + TACE+ RFA group were higher than that in TACE+ RFA group at 6 months (94.7%±3.6% vs 81.3%±6.4%, Z=24.1>2.58, P=0.00), 1 year (89.2%±5.1% vs 40.7%±8.3%, Z=13.3>2.58, P=0.00) and 2 year (55.9%±8.6% vs 29.6%±8.2%, Z=7.2>2.58, P=0.00). The median OS were 42 months in (125)I + TACE+ RFA group and 30 months in TACE+ RFA group, χ(2)=4.76, P=0.029.The survival cumulative rate in (125)I+ TACE+ RFA group were higher than that in TACE+ RFA group at 1 year (92.1%±4.4% vs 83.8%±6.1%, Z=23.5>2.58, P=0.00), 2 year (75.8%±7.0% vs 59.8%±8.4%, Z=12.43>2.58, P=0.00), 3 year (59.0%±8.2% vs 41.7%±8.9%, Z=8.3>2.58, P=0.00), 5 year (34.2%±8.2% vs 18.2%±8.1%, Z=5.5>2.58, P=0.00). In addition, there was no statistical difference in liver function and complications between TACE+ RFA group and (125)I+ TACE+ RFA group. Conclusion: (125)I radioactive seed implantation plus TACE combined with RFA treatment is an effective and safe treatment for sub-capsular hepatocellular carcinoma.

Cytokine production in vitro by macrophages of goats with caprine arthritis-encephalitis

The response of caprine macrophages to exposure to caprine arthritis-encephalitis virus (CAEV) and lipopolysaccharide (LPS) was investigated in female Nubian and Nubian crossbreed of goats. Macrophages were matured in vitro from monocytes isolated from blood of control and CAEV-infected goats and the concentrations of tumor necrosis factor (TNF-alpha) and interleukin-6 (IL-6) in culture supernatant after exposure of cells to LPS and virus were assayed. Though barely detectable in unstimulated cells, TNF-alpha and IL-6 levels showed peak values of 420 +/- 28 to 530 +/- 32 and 70 +/- 27 to 93 +/- 29, respectively, in supernatants of control goat cells [corrected], remaining high through 24 hrs. post treatment with LPS stimulation. Exposure of these control goat cells [corrected] to virus induced lower secretions (p<0.05) of the cytokines. The peak values occurred between 6 and 12 hrs. post treatment with LPS or virus. Cells prepared from virus-infected goats and treated with the mitogen or virus showed significantly (p<0.05) lower response than those from control goats. The present results suggest a dysregulation, possibly downregulation of the production of both cytokines in macrophages of goats chronically diseased by lentivirus infection.
