Phenyl-Extended Resorcin[4]arenes: Synthesis and Highly Efficient Iodine Adsorption.

The continuous exploration of new analogs of calixarenes and pillararenes unlocks infinite opportunities in supramolecular chemistry and materials. In this work, we introduce a new class of macrocycle, phenyl-extended resorcin[4]arenes (ExR4), a unique and innovative design that incorporates unsubstituted phenylene moieties into the resorcin[4]arene scaffold. Single-crystal analysis reveals a chair-like conformation for per-methylated ExR4 (Me-ExR4) and a twisted "figure-of-eight" shaped conformation for per-hydroxylated ExR4 (OH-ExR4). Notably, OH-ExR4 demonstrates exceptional adsorption capability toward I3- ions in an aqueous solution, with a rapid kinetic rate of 1.18×10-2 g·mg-1·min-1. Furthermore, OH-ExR4 shows excellent recyclability and potential as a stationary phase in column setups. The discovery of ExR4 opens up new avenues for constructing new macrocycles and inspires further research in functional adsorption materials for water pollutant removal.

[Efficacy of medicinal penetration on acupoint as adjunctive therapy on histiocytic necrotizing lymphadenitis of heat-toxin syndrome: a randomized controlled trial].

OBJECTIVE: To evaluate the clinical efficacy of medicinal penetration on acupoint combined with medication for histiocytic necrotizing lymphadenitis (HNL) of heat-toxin syndrome, and to explore the methods of improving the clinical effect. METHODS: A total of 72 cases with HNL with heat-toxin syndrome were randomly divided into an observation group and a control group, 36 cases in each group. The patients in the control group were treated with oral administration of prednisone tablets for 40 days (first 5 days: 10 mg, three times a day; since then, reduced by 5 mg every 7 days). In the observation group, on the basis of the medication in the control group, the patients were treated with acupoint application and ultrasonic drug penetration therapy, once a day for 14 days. The acupoints of Waiguan (TE 5), Fengchi (GB 20) of affected side and ashi points were selected. The changes of target lymph node swelling, visual analogue score (VAS), axillary temperature and total score of symptoms and signs were evaluated before treatment and 7, 14, 28 and 40 d into treatment; the changes of white blood cell (WBC), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and lactic dehydrogenase (LDH) were evaluated on 14 d and 40 d into treatment; the patients were followed-up for half a year. RESULTS: ① Fourteen days into treatment, the clinical cured rate in the observation group was 38.9% (14/36), which was superior to 16.7% (6/36) in the control group (P<0.01); the clinical cured rates were both 100% in the two groups on 40 d into treatment. ② The VAS score, axillary temperature and the total score 7 d into treatment, as well as node swelling, VAS score, axillary temperature and the total score 14, 28 and 40 d into treatment in the two groups were significantly improved (P<0.01); the total score and VAS score of 7 d into treatment, target lymph node swelling, VAS score and total score of 14 d into treatment in the observation group were significantly improved than those in the control group (P<0.01). ③ Compared before treatment, WBC, CRP, ESR in the two groups were significantly improved 14 d and 40 d into treatment (P<0.01), and LDH in the two groups were decreased 40 d into treatment (P<0.01), but there was no significant difference between the two groups (P>0.05). ④ The recurrence rate in the observation group was 5.6% (2/36), which was similar to 16.7% (6/36) in the control group (P>0.05). CONCLUSION: The medicinal penetration on acupoint as adjunctive treatment could effectively relieve the discomfort symptoms of HNL patients with syndrome of heat and toxin, improve the clinical cured rate, and provide the research direction for shortening the course of medication.

[Correlation between TCM syndrome types and clinical symptoms of benign prostatic hyperplasia with chronic prostatitis].

OBJECTIVE: To investigate the correlation between the syndrome types of traditional Chinese medicine (TCM) and clinical symptoms of benign prostatic hyperplasia (BPH) with chronic prostatitis (BPH-CP). METHODS: We selected 150 cases of BPH-CP in this study and divided them into 7 TCM syndrome types. Using univariate and multivariate logistic regression analyses, we studied the correlation of each TCM syndrome type with the age, disease course, prostate volume, postvoid residual urine volume (PVR), prostate-specific antigen (PSA) level, maximum urinary flow rate (Qmax), and International Prostate Symptoms Score (IPSS). RESULTS: Kidney-yin deficiency was correlated positively with the prostate volume but negatively with Qmax and IPSS; kidney-yang deficiency positively with the age and prostate volume but negatively with IPSS; the damp heat syndrome positively with the PSA level but negatively with the disease course, prostate volume and Qmax; the spleen-qi deficiency syndrome positively with the prostate volume but negatively with the disease course; liver-qi stagnation positively with the disease course but negatively with the age, prostate volume and PVR; the syndrome of qi stagnation and blood stasis positively with the disease course and IPSS but negatively with PVR; the syndrome of lung-heat and qi blockage positively with the age, Qmax and IPSS but negatively with the disease course. CONCLUSIONS: The TCM syndrome types of BPH-CP are closely correlated to their clinical symptoms. The analysis of the clinical objective indexes of BPH-CP can provide some reliable evidence for accurate identification of the TCM syndrome type of the disease.
