Journal of Preventive Medicine 2002;12(3):50-55
To study the preventive effects of zinc supplementation on malnutrition during the first months of life (5-7 months of age) in healthy Vietnamese children. Infants were divided into 2 groups: one received for 6 months a syrup containing 10mg of zinc, other group received a placebo. The results showed that, zinc level in all groups were higher than in placebo group. Zinc administration increased the growth velocity of weight and height compared with placebo, particularly in female. Growth factor-I (IGF-I) levels decreased from 26ng/mL to 25ng/mL for both groups, but increased by 10% in the zinc treated females.

Anti-HIV drugs still remain as the dominant role in the treatment of acquired immunodeficiency syndrome (AIDS), because no vaccine was found till today. Owing to structural diversity, few side effects, and abundant resources, natural compounds from traditional Chinese medicines and medicinal plants have unique advantages and good potential in prevention and treatment of AIDS. Many researchers have made great efforts in the field of anti-HIV natural compounds, and have found some natural compounds from traditional Chinese medicines with potent anti-HIV activities. These compounds can be classified into the following categories: alkaloids, coumarins, lignans, flavonoids, terpenoids, tannins, polysaccharides, proteins and peptides, and polyphenols. However, most of these researches are performed in vitro, and most natural compounds show weak anti-HIV activities and indefinite acting targets. In the paper, we reviewed some natural compounds derived from traditional Chinese medicines with potent anti-HIV activities in recent years.

Objective We characterized the clinical features of sporadic Creutzfeldt-Jakob disease(sCJD)in or?der to diagnose it at the early stage. Methods Seventeen patients with sCJD were enrolled in the study. The clinical data, symptoms at the early stage, result of auxiliary examinations and survival time were analyzed. Results The ratio of male to female was 1:1.83 and the average age of onset was 60 ± 8.8 years old. Most of them presented with walking unstable (82.4%)and hypomnesia (64.7%) as the initial symptom. The occurrence rate was 82.4%, 76.5%and 58.8%for myoclo?nus, colored-ribbon-shaped high signals in cerebral cortex and high signals in basal ganglia of MRI. Periodic synchro?nous discharge (PSD) of electroencephalography(EEG) was seen in 82.4% cases, while cerebrospinal fluid analysis re?vealed positive results for 14-3-3 protein in 70%cases. Twelve patients had been dead in our study. The median surviv?al time was 12±7.7 months. Conclusions sCJD is more frequently occurred in mid-aged and older without specific symp?toms in early stage and positive rate of high signals in cerebral cortex of MRI and PSD of EEG is high.

Using of clearing zones on pachyman agar medium, there are 217 plant endophytic actinomycetes, producing ?-1,3-glucanase were screened. 45.6% of the strains produced ?-1,3-glucanase, in which the strains from cucumber are up to 38. The percentages of endophytic actinomycetes from different hosts produceing ?-1,3-glucanases were different. The percentage of the strains in Rhizoma Polygonatum produced ?-1,3-glucanases is the highest, up to 88.9%. The Inhibited effects of plant endophytic actinomycetes which produced extracellular ?-1,3-glucanases on mycelium growth of Sclerotinia sclerotiorum were detected in vitro. Cucumber endophytic actinomycete gCLA4 strain was screened out from 99 isolates, which can strongly inhibit the growth of S. sclerotiorum. The optimal ?-1,3-glucanases fermentation conditions of strain gCLA4 were investigated, they were pachyman 0.2%, peptone as nitrogen, pH 7~8 for 5 days. The ?-1,3-glucanases of strain gCLA4 had some inhibiting efficiency on 13 plant pathogens, in which inhibiting efficiency to Botryosphaeria dothidea was the strongest.

Keratorefractive surgery changes the central corneal thickness (CCT) and corneal curvature, which could influence the Goldmann applanation tonometer (GAT) and non-contact tonometer (NCT) measurements of intraocular pressure (IOP), but not dynamic contour tonometer(DCT). During the procedure of LASIK, there is a transient rise of IOP, which increases the risks of optic nerve damage. Meanwhile, the presence of functioning filtering blebs may affect the choice and outcome of refractive surgery, or even becomes a contraindication of surgery. Steroids are typically used after keratorefractive surgery, which could lead to IOP elevation. Hence it is important to monitor IOP after LASIK and to be aware of inaccurate IOP readings due to corneal flap interface fluid. Treating patients with postoperative elevated IOP after keratorefractive surgery is similar to that for patients with glaucoma. This review will address the issues surrounding the safety, relevant complications and implications of keratorefractive surgeries on glaucoma and relevant diagnostic tests.

OBJECTIVETo study the effect of Zhibai Dihuang Pill (ZBDHP) on urokinase-type plasminogen activator (uPA) and sperm quality in ureaplasma urealyticum (Uu) infection infertile patients.
METHODSRecruited were 80 infertility patients with Uu infection at Andriatrics Clinics and Department of Reproduction, including 130 cases of positive Uu semen and 50 cases of negative Uu semen. Patients with positive Uu semen were randomly assigned to the observation group (72 cases) and the control group (58 cases) according to the visit sequence. All patients took antibiotics for 2 weeks. Patients in the observation group additionally took ZBDHP, 6 g each time, twice daily. Those in the control group additionally took Vit E (100 mg each time, twice per day) and ATP (40 mg each time, twice per day). The therapeutic course for all was 90 days. Semen parameters and uPA contents of the sperm membrane were detected and comparatively analyzed.
RESULTSThe sperm membrane uPA content, the sperm motility, the sperm viability, and the percentage of normal morphology sperm in Uu positive infected patients were lower than those in Uu negative infected patients with statistical difference (P < 0.05), but with no significant difference in the sperm density between the two groups (P > 0.05). There was no statistical difference in pre-treatment sperm membrane uPA contents and sperm parameters between the two groups (P > 0.05). Compared with before treatment in the same group, the sperm membrane uPA content, the sperm motility, the sperm viability, and the percentage of normal morphology sperm obviously increased in the two groups with statistical difference (P < 0.05). After treatment, the sperm membrane uPA content increased more obviously in the observation group, with statistical difference when compared with the control group (P < 0.05).
CONCLUSIONSInfection with Uu leads to decreased uPA content of sperm membrance and the sperm motility. ZBDHP could effectively treat Uu infected infertility possibly through fighting against Uu damaged sperm membrane and make the sperm membrane uPA content return to normal, and elevate the fertilizability of sperms.
