OBJECTIVE:
The research progress of new multifunctional bone cement in bone tumor therapy in recent years was reviewed, in order to provide help for the future research of anti-tumor bone cement.
METHODS:
The related literature on the treatment of bone tumors with new multifunctional bone cement at home and abroad in recent years was extensively reviewed and summarized.
RESULTS:
The new multifunctional bone cements include those with the functions of photothermotherapy, magnetic thermotherapy, chemoradiotherapy, and antibacterial after operation, which are discussed from the aspects of anti-tumor, drug controlled release, and cytotoxicity. Controlled drug release has been achieved in multifunctional bone cements by adjusting heat and pH or incorporating particles such as chitosan oligosaccharides and γ-cyclodextrin. At present, multifunctional bone cement with hyperthermia, radiotherapy, and chemotherapy has effectively inhibited the local recurrence and distant metastasis of bone tumors. Broadening the application of bone cement for photothermal and magnetic thermal therapy to deeper bone tumors, investigating more precise controlled release of drug-loaded bone cement, and introducing nanoparticles with both thermal conversion and intrinsic enzymatic activities into bone cement for synergistic anti-tumor therapy are promising research directions.
CONCLUSION
The new multifunctional bone cement inhibits bone tumor cells, promotes new bone formation in bone defects, and prevents incision infection after tumor resection. Certain progress has been made in anti-tumor, antibacterial, drug-controlled release, and reduction of cytotoxicity. Expanding the deeper application range of the new multifunctional bone cement, verifying the safety in clinical application, and focusing on the individualized treatment of the new multifunctional bone cement are the problems that need to be solved in the future.

This study aimed to systematically evaluate the efficacy and safety of different Chinese patent medicines in the treatment of idiopathic membranous nephropathy. The relevant randomized controlled trial(RCT) was retrieved from PubMed, EMbase, Cochrane Library, CNKI, SinoMed, Wanfang, and VIP with the time interval from database inception to December 2022. The Cochrane risk of bias assessment tool was employed to evaluate the quality of the included RCT, and Stata 15.0 and GEMTC to perform the Bayesian network Meta-analysis. Finally, 51 RCTs were included, involving 9 Chinese patent medicines and 3 591 patients. The results of network Meta-analysis showed that in terms of the total effective rate and the increase in plasma albumin, the top three interventions were Zhengqing Fengtongning Sustained Release Tablets + conventional western medicine, Bailing Capsules + conventional western medicine, and Tripterygium Glycosides Tablets + conventional western medicine. In terms of reducing 24-hour urine total protein, the top three interventions were Zhengqing Fengtongning Sustained Release Tablets + conventional western medicine, Shenfukang Capsules +conventional western medicine, and Huangkui Capsules + conventional western medicine. In terms of reducing serum creatinine, the top three interventions were Shenfukang Capsules + conventional western medicine, Bailing Capsules + conventional western medicine, and Zhengqing Fengtongning Sustained Release Tablets + conventional western medicine. In terms of safety, Chinese patent medicines combined with conventional western medicine had fewer adverse reactions than the control group. The results suggest that Chinese patent medicines combined with conventional western medicine can improve the therapeutic effect on idiopathic membranous nephropathy, and differentiated medications can be adopted according to the specific symptoms of patients in clinical treatment. Further validation needs to be carried out in the future with multi-center, large-sample, and high-quality RCT.

OBJECTIVE:
To prepare an injectable hydrogel/staple fiber composite loaded with combretastain A-4 disodium phosphate (CA4P) and doxorubicin (DOX) and evaluate its antitumor efficacy via intratumoral injection.
METHODS:
DOX-loaded PELA staple fibers (FDOX) were prepared using electro-spinning and cryo-cutting, and the drug distribution on the surface of the fibers was observed using a fluorescence microscope, and the encapsulation efficiency and loading capacity of FDOX were determined with a fluorospectro photometer. The fibers were then dispersed in CA4P-loaded PLGA-PEG-PLGA tri-block polymer solution at room temperature to obtain the hydrogel/staple fiber composite (GCA4P/FDOX). The thermo-sensitivity of this composite was determined by a test tube inverting method. An ultraviolet spectrophotometer and a fluorospectrophotometer were used to detect the release profile of CA4P and DOX, respectively. We observed in vivo gel formation of the composite after subcutaneous injection in mice. The in vitro cytotoxicity of GCA4P/FDOX composite in MCF-7 and 4T1 cells was assessed using cell Counting Kit-8 (CCK-8) reagent. In a mouse model bearing breast tumor 4T1 cell xenograft, we evaluated the antitumor efficacy of the composite by monitoring tumor growth within 30 days after intratumoral injection of the composite. HE staining, immunohistochemistry for Ki67 and immunofluorescence (TUNEL) assay were used for pathological examination of the tumor tissues 21 days after the treatments.
RESULTS:
The average length of FDOX was 4.0±1.3 μm, and its drug loading capacity was (2.69±0.35)% with an encapsulation efficiency of (89.70±0.12)%. DOX was well distributed on the surface of the fibers. When the temperature increased to 37 ℃, the composite rapidly solidified to form a gel in vitro. Drug release behavior test showed that CA4P was completely released from the composite in 5 days and 87% of DOX was released in 30 days. After subcutaneous injection, the composite solidified rapidly without degradation at 24 h after injection. After incubation with GCA4P/FDOX for 72 h, only 30.6% of MCF-7 cells and 28.9% of 4T1 cells were viable. In the tumor-bearing mice, the tumor volume was 771.9±76.9 mm3 in GCA4P/FDOX treatment group at 30 days. Pathological examination revealed obvious necrosis of the tumor tissues and tumor cell apoptosis induced by intratumoral injection of G4A4P/FDOX.
CONCLUSION
As an efficient dual drug delivery system, this hydrogel/staple fiber composite provides a new strategy for local combined chemotherapy of solid tumors.

In this study, insulin (insulin, INS)/Ca3PO4 complex and glucose oxidase (glucose oxidase, GOx)/Cu3(PO4)2 complex were prepared by coprecipitation method. The mineralized insulin (mineralized insulin, m-INS) showed irregular crystalline clusters, and the mineralized glucose oxidase (m-GOx) showed flower spherical morphology, with a diameter of about 1-2 μm. In vitro simulated release experiment showed that m-INS released INS as the pH value of the medium decreased. When the pH value was 4.5, the release amount reached 96.68%. The enzyme activity detection experiment showed that the enzyme activity stability of m-GOx was higher than that of free GOx. It still maintained high activity after 10 days at room temperature, while the activity of GOx was less than 60%. The glucose solution was prepared to simulate the state of normal blood glucose (5.6 mmol/L) and hyperglycemia (22.2 mmol/L). When m-INS and m-GOx were added to the glucose solution, the release amount of INS showed a significant glucose concentration dependence. The higher the glucose concentration, the greater the release amount and release rate of INS. Finally, m-INS, m-GOx and hyaluronic acid (HA) solution were mixed to prepare HA microneedle arrays loaded with m-INS and m-GOx. Type 1 diabetes mice were constructed to evaluate the effect of drug-loaded HA microarray on blood glucose control in diabetic rats. The results show that the HA microneedles loaded with m-INS/m-GOx could deliver drugs effectively. The average blood glucose concentration in diabetic rats dropped to about 7 mmol/L within 1 h, normal blood glucose concentration could be maintained for 10 h, and the overall blood glucose concentration was lower than the level before administration for 36 hours. Compared with HA microneedles loaded with INS only, m-ins microneedles showed better glucose tolerance, longer-lasting glucose control effect and less risk of hypoglycemia. Compared with other sustained-release systems, the preparation process of the core components in this study is simple, efficient, safe and effective, and has great commercial potential.

Chinese journal of integrative medicine 2022;28(10):909-917
OBJECTIVE:
To verrify the anti-tumor efficacy and toxicity between juglone (Jug) and Jug-loaded PLGA nanoparticles (Jug-PLGA-NPs).
METHODS:
Jug-PLGA-NPs were prepared by ultrasonic emulsification. The anti-tumor activity of Jug (2, 3, 4 µg/mL) and Jug-PLGA-NPs (Jug: 2, 3, 4 µg/mL) in vitro was measured by MTT assay and cell apoptosis analysis. The distribution, anti-tumor effect and biological safety in vivo was evaluated on A375 nude mice.
RESULTS:
With the advantage of good penetration and targeting properties, Jug-PLGA-NPs significantly inhibited proliferation and migration of melanoma cells both in vitro and in vivo (P<0.05 or P<0.01) with acceptable biocompatibility.
CONCLUSIONS
Jug can inhibit the growth of melanoma but is highly toxic. With the advantage of sustained release, tumor targeting, anti-tumor activity and acceptable biological safety, Jug-PLGA-NPs provide a new pharmaceutical form for future application of Jug.

OBJECTIVE:
To compare the clinical efficacy of acupoint catgut embedding and bupropion hydrochloride sustained-release tablets in the treatment of tobacco dependence.
METHODS:
A total of 100 patients with tobacco dependence who met the inclusion criteria were randomly divided into an acupoint catgut embedding group and a drug group, 50 cases in each group. In the acupoint catgut embedding group, acupoint catgut embedding was applied at Xinshu (BL 15), Shenmen (HT 7), Tianmei (Extra), Taichong (LR 3), the treatment was given once every 2 weeks for 4 times; The bupropion hydrochloride sustained-release tablets was orally administered in the drug group for 7 weeks, 150 mg each time, once a day for the first 3 days, twice daily from day 4 to day 7, and once a day after day 8. The Fagerström test for nicotine dependence (FTND) score before and after treatment, the 4th and 8th week smoking cessation rate, the continuous smoking cessation rate and efficacy, compliance rate and adverse reaction rate were compared in the two groups.
RESULTS:
A total of 100 patients were enrolled, and 97 patients completed the study (loss rate was 3%), including 49 cases in the acupoint catgut embedding group and 48 cases in the drug group. The FTND scores in the two groups were lower than those before treatment (both <0.05). There was no significant difference between the two groups after treatment (>0.05). At the 4th and the 8th week, the smoking cessation rate in the acupoint catgut embedding group was 40.8% (20/49) and 79.6% (39/49) respectively, the smoking cessation rate in the drug group was 41.7% (20/48) and 83.3% (40/48) respectively, the two groups were equally effective (both >0.05). The continuous smoking cessation rate in the acupoint embedding group was 40.8% (20/49), which was equivalent to 41.7% (20/48) in the drug group (>0.05). The rate of complete compliance in the acupoint embedding group was 61.2% (30/49), which was significantly better than 37.5% (18/48) in the drug group (<0.05). The adverse reaction rate in the acupoint catgut embedding group was 12.2% (6/49), which was significantly lower than 29.2% (16/48) in the drug group (<0.05).
CONCLUSION
Acupoint catgut embedding can effectively improve the symptoms of tobacco dependence after smoking cessation. Its curative effect is close to that of bupropion hydrochloride sustained-release tablets, and it has good clinical compliance and less adverse reactions.

Objective:
To study the therapeutic effect of Lamiophlomis Rotata Capsule (LRC) in the treatment of type ⅢB prostatitis.
METHODS:
We randomly divided 225 patients with type ⅢB prostatitis into an experimental group (n =125) and a control group (n =120), the former treated orally with LRC at 3 capsules tid while the latter with tamsulosin hydrochloride sustained-release capsules at 0.2 mg qd, both for 4 weeks. We compared the therapeutic effects between the two groups of patients based on the National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI) obtained before, immediately after and at 4 weeks after medication.
RESULTS:
A total of 120 patients completed the treatment in the experimental group, which showed remarkable decreases as compared with the baseline in the pain score (5.30 ± 1.23 vs 14.68 ± 1.51, P<0.05), quality of life (QoL) score (6.46 ± 0.93 vs 8.52 ± 1.05, P<0.05) and total NIH-CPSI score (17.50 ± 2.77 vs 27.99 ± 2.98, P<0.05) after 4 weeks of treatment, but no significant change in the urination symptoms score (7.41 ± 1.16 vs 7.16 ± 1.04, P>0.05). The experimental group achieved even markedly lower scores than the controls in the pain symptom (5.30 ± 1.23 vs 13.67 ± 1.49, P<0.05), QoL (6.46 ± 0.93 vs 7.47 ± 0.88, P<0.05) and total NIH-CPSI (17.50 ± 2.77 vs 25.77 ± 2.01, P<0.05) but a higher urination symptoms score than the latter after medication (7.16 ± 1.04 vs 5.68 ± 1.34, P<0.05). At 4 weeks after drug withdrawal, the experimental group also showed significantly lower scores of the pain symptom (7.23 ± 1.03), QoL (6.58 ± 0.87) and total NIH-CPSI (22.18 ± 2.03) than the baseline (all P<0.05) and those in the control group (14.14 ± 0.98, 8.12 ± 0.72 and 26.89 ± 1.67) (all P<0.05). Apart from dizziness in 2 of the patients, who gave up medication halfway, no other obvious adverse reactions were observed during the experiment.
CONCLUSIONS
Lamiophlomis Rotata Capsule deserves to be recommended for the treatment of type ⅢB prostatitis for its safety and effectiveness in reducing the pain and improving the life quality of the patients.

PURPOSE: The administration of recombinant human growth hormone in adults with growth hormone deficiency has been known to improve metabolic impairment and quality of life. Patients, however, have to tolerate daily injections of growth hormone. The efficacy, safety, and compliance of weekly administered sustained-release recombinant human growth hormone (SR-rhGH, Declage(TM)) supplement in patients with growth hormone deficiency were evaluated. MATERIALS AND METHODS: This trial is 12-week prospective, single-arm, open-label trial. Men and women aged > or =20 years with diagnosed growth hormone deficiency (caused by pituitary tumor, trauma and other pituitary diseases) were eligible for this study. Each subject was given 2 mg (6 IU) of SR-rhGH once a week, subcutaneously for 12 weeks. Efficacy and safety at baseline and within 30 days after the 12th injection were assessed and compared. Score of Assessment of Growth Hormone Deficiency in Adults (AGHDA score) for quality of life and serum IGF-1 level. RESULTS: The IGF-1 level of 108.67+/-74.03 ng/mL was increased to 129.01+/-68.37 ng/mL (p=0.0111) and the AGHDA QoL score was decreased from 9.80+/-6.51 to 7.55+/-5.76 (p<0.0001) at week 12 compared with those at baseline. Adverse events included pain, swelling, erythema, and warmth sensation at the administration site, but many adverse events gradually disappeared during the investigation. CONCLUSION: Weekly administered SR-rhGH for 12 weeks effectively increased IGF-1 level and improved the quality of life in patients with GH deficiency without serious adverse events.
